In Great Britain October 22, 1932 81 Claims.

This invention relates to machines for operating on shoe uppers to impart to each upper, or to a portion thereof, the shape that it is to have in the finished shoe. In prior United States Letters Patent No.,1,897,037, granted on February 14, 1933 upon an application of mine, there was disclosed a machine constructed to operate upon a previously untensioned upper to tension it over a last and to work the forepart of the upper into lasted relation to the last and to an insole on the last. Among its objects, the present invention has particularly in view certain improvements in a machine organization of the general character there disclosed, and it is accordingly herein illustrated as applied to such an organization; but it is to be understood that in various novel aspects the invention is not thus limited in its applicability.

In one aspect, the invention provides novel means for applying a binder to an upper around an end of a shoe to hold the upper in lasted position. In the illustrative machine the marginal portion of the upper around the toe is wiped into lasted position against a lip on the insole by toe-embracing wipers; and for the purpose in view the construction herein shown comprises grippers that grip a wire binder at the opposite sides of the shoe and are moved relatively to the wipers, in response to the operative movement of the wipers, to pull the binder tight- 1y against the margin of the upper. As further herein illustrated, the wipers are provided at their wiping edges with a groove to receive the binder, and prior to the operation of the machine the operator places the binder in this groove and in the above-mentioned grippers which are located beyond the rear ends of the wipers.

Further novel features of the invention are to be recognized in the combination of binder-applying means and means for fastening the binder to the shoe, and also in details of the fastening means. As herein illustrated, the binder is fastened by staples driven in notches located at the wiping edges of the wipers, but it is to be understood that the invention is not limited to the use of staples nor to means for driving the fastenings in that relation to the wipers. In the construction shown, similarly to the disclosure of the above-mentioned Letters Patent, the wipers are extended lengthwise of the shoe to wipe the upper into lasted position substantially as far rearwardly as the ball line of the shoe; and to fasten the binder there are driven at each side of the shoe bottom a pair of staples located respectively near the toe tip line and at the ball of the shoe.. For greater security in the holding of the binder, the invention provides means for driving staples the legs of which diverge from each other toward their work-penetrating ends and are spaced from each other near their cross- 5 bars by distances less than the diameter of the binder to cause them to clamp the binder between them as they are driven; and in this aspect of the invention a novel method also is to be recognized. The fastenings are driven, in the illusl0 trative machine, from guides that are movable relatively to the wipers both heightwise and laterally of the shoe into fastening-inserting positions; and in accordance with a further feature of the invention these guides are so constructed 15 and operated that they press the binder against the upper prior to the driving of the fastenings. In accordance with still other features novel means are provided for operating and controlling the guides for the fastenings and for operating and controlling the drivers that drive the fastenings.

The machine disclosed in the above-mentioned Letters Patent included'grippers arranged to grip the marginal portion of the upper outspread at the opposite sides of the toe and movable inwardly toward the last in response to the pull of the upper-thereon in the upper-shaping operation. The present invention provides additional grippers for similarly controlling the upper farther rearwardly than the toe portion, these grippers in the construction shown being arranged to grip the upper in locations slightly nearer the toe than the ball line. A feature of the invention also is to be recognized in novel details of construction of these grippers and of their operating and controlling means.

The above and other features of the invention, including also novel means for clamping the upper about the forepart and novel means for positioning the upper relatively to the upper-shaping means, will now be more particularly described by reference to the accompanying drawings and pointed out in the claims.

Similarly to the disclosure of the above-mentioned Letters Patent, the machine in which the invention is herein illustrated as embodied comprises two sets of operating instrumentalities arranged side by side on a common base I for operating respectively on right and left shoes. For an understanding of the invention, however, it is necessary to refer only to one of these sets of instrumentalities, and accordingly portions only of that set which is located at the right-hand side of the machine are herein shown and will be described in detail.

In general similarity to the disclosure of the above-mentioned Letters Patent, there are provided, for supporting the last in the course of the operation of the machine and for pressing the upper against portions of the last, two inflatable pads 3 which engage the upper underneath and along the sides of the last at the rear of the toe portion and a pad 5 which engages the upper under the toe end of the last, the several pads being mounted on a support 6 that is movable downwardly against the resistance of a spring (not shown). For depressing the last and forcing it into the upper there is provided a downwardly swinging arm 1 which carries a block 9 pivoted at H on the arm to permit relative movement between it and the arm in responseto resistance of the support 6 and its spring to downward movement of the last so as to impart to the last a lengthwise upper-stretching movement, as fully disclosed in said Letters Patent. The block 9 carries a toe plate l3 (Fig. 2) arranged to engage the toe end of the insole on the last and a presser foot [5 arranged to engage the insole at the waist portion of the shoe. Similarly also to one form of construction disclosed in the earlier Letters Patent, the block 9 carries a toe-end abutment ll arranged to engage the toe-end face of the last to assist in imparting to the last its lengthwise movement. In general similarity likewise to the earlier machine, there are provided clamp members I8 which clamp the marginal portion of the toe end of the upper outspread upon toe-embracing wipers 2i so as to tension the upper over the last both lengthwise and heightwise thereof in response to the movement of the last, and grippers [9 (Figs. 2 and 3) which grip the margin of the upper outspread over the wipers near the ends of the tip line to'assist in tensioning the upper, these grippers being mounted for inward swinging movements toward the last against spring resistance about pivots 25 extending lengthwise of the last and supported on brackets 21 that are secured to the head of the machine near the front of the latter. In the construction herein shown, as more particularly hereinafter described, there are further provided two additional grippers 23 arranged to grip the margin of the upper at or near the ball of the shoe, these grippers being utilized in place of the members H4 shown in the previously mentioned Letters Patent as arranged to clamp portions of the margin of the upper upon the wipers.

In the construction herein shown, for purposes of the present invention, there are two swinging brackets 29, one at each side of the shoe, which serve as carriers for staple-inserting mechanisms hereinafter described, each of these brackets being mounted to swing downwardly and inwardly about a pivot 3i extending lengthwise of the shoe and secured to the front face of the bracket 21, the pivot being located near the upper end of the bracket and at the inner side thereof, i. e., the side which is nearer the shoe. Each of the swinging brackets 29 has mounted in it at its outer. side a rotatable pin 33 extending lengthwise of the shoe, and on this pin is pivotally mounted a short depending link 35 connected at its lower end'to the upper end of a vertical rack bar 31 slidable vertically in a fixed guideway 39 in the bracket 21. Each rack bar 31 is engaged at its lower end by a. pinion 4| (Fig. l) which also meshes with a horizontal rack bar 43 extending lengthwise of the shoe. The two horizontal rack bars 43 are connected together by pinions 45 secured to the opposite ends of a rotatable shaft 41 mounted in fixed bearings and extending laterally of the shoe, so that movement of one rack bar 43 causes a similar movement in the same direction to be imparted to the other rack bar. One of the rack bars 43 is connected at its rear end by a link 49 to the upper end of a cam-operated lever (not shown). By the operation of this lever accordingly swinging movements are imparted to the two opposite brackets 29, the lower end portions of which are thus swung toward and from each other as well as downwardly and upwardly.

The above-mentioned rotatable pin 33 in each of the swinging brackets 29 has freely pivoted on it a pair of short inwardly extending arms 5| which are pivotally connected at their inner ends, by pivot pins 53 extending lengthwise of the shoe, to the upper ends of a pair of staple and driverguiding tubes 55. These tubes are spaced apart lengthwise of the shoe and extend downwardly and rearwardly (i. e., away from the front of the machine) at an angle of about 10 to the vertical (Fig. 1). The tubes 55 have formed on them at their front and rear sides flat guiding faces 57 (Figs. 3 and 6) which are received between guiding faces provided on inwardly extending lower portions 59 of the swinging bracket 29. Substantially horizontal springs 6i (one of which is shown in Fig. 3) extending laterally of the machine are connected at their inner ends to the lower portions of. the tubes 55 and at their outer ends to hooks fixed in the bracket 29, the springs thus serving to urge the tubes outwardly along the guiding faces on the bracket until they abut against adjustable stop screws 63 threaded substantially horizontally into the portions 59 of the bracket. A pair of upwardly extending rods 85 lying one behind the other, one for each of the previously mentioned inwardly extending arms 5!, are pivoted at their lower ends to pins 6'! on sides of these trunnion bearings and nuts I8 on the upper ends of the rods 85 and serve to urge the arms 5| and the driver-guiding tubes 55 downwardly until they are arrested by contact of the arms 5| with adjustable stop screws I5 positioned below the arms and mounted as hereinafter described.

Staple drivers 'I'I (Fig. 6) comprising rods each I of awidth slightly greater than the length of the head or crossbar of a staple to be driven are located in driver-guiding passages in the tubes 55, and the two, staple drivers at each side extend downwardly from the lower ends of a pair of driver bars 18 which are slidable in the tubes 55 and are connected together at their upper ends by a leaf spring 8| (Fig. 1) which serves normally to maintain the lower ends of the two drivers 11 at the same height and yet allows them to settle firmly against the work independently of each other at the end of their staple-driving movements. The upper ends of the two bars I8 at each side are also connected to ball-shaped opposite ends of a short link or rocker 88 on the central portion of which is swiveled a sleeve 85. An upwardly extending operating rod 81 for the two staple drivers is connected at its lower end by a transverse pivot to the sleeve 85 and is connected at its upper end to the forward end of a pivoted forwardly extending spring-operated arm 88. A second rod 8| is also connected at its upper end to the driver-operating arm 88 and is connected 'at its lower end. to an arm 83 which is freely pivoted at 85 (Fig. 3) to the swinging bracket 28. By reason of the pivotal connection between the arm 83 and the bracket 28, the bracket can swing about its pivot 3| without exercising any pulling action on the rod 9 I. The rod 9| is driven downwardly by the arm 89 in company with the driver bars I8, and at the end of its downward movement a screw 91 carried by the arm 93 is arranged substantially to contact with the upper face of the bracket 29, so that when this bracket is later swung outwardly and upwardly about its pivot 3| after the staple-driving operation through the action of the previously described rack and pinion mechanism, it serves through the rod 9| to raise the driver-operating arm 89 against the resistance of a torsion spring 89 which operates the arm. The arm 89 is held in its upraised position by a pawl I88 until it is released by the pawl to effect the staple-driving operation in the next cycle of the machine. The pawl is controlled by a cable I82 by which it is connected to cam-operated mechanism (not shown) A staple carrier or magazine IN is securedto each driver-guiding tube 55 nearthe lower end thereof and comprises a metal staple-supporting strip I83 (Figs. 3 and 6) which extends rearwardly and upwardly. The inner end of this strip leads into the driver-guiding passage in the tube 55 substantially at the forward side of the passage (i. e., the side nearer the operator) and near the lower end of the passage so that the staples may pass from the strip directly into the passage. A plurality of unconnected U-shaped staples I84 formed of relatively fine round wire are placed in a row upon each staple-supporting strip I83 by the operator, with the work-penetrating ends of thestaples hanging downwardly. A staple-feeding member I85, which is freely movable along an easily removable rod I88 having a head I 81 secured in place in the magazine by a bayonet joint, straddles the strip I88 and is urged inwardly toward the driver passage by a a spring I88 which surrounds the removable rod, the member I85 engaging the outer end of the row of staples to urge them along the supporting strip until the staple at the inner end of the row actually lies within the driver passage in the tube 55. Thelegs of the staples, as formed in a conventional staple-forming machine, usually diverge somewhat toward their work-penetrating ends", and in order that this fact may not hinder the entry of the staples into the driver guiding passage, the width of which is but little greater than the lengths of the crossbars of the staples, each passage is widened close to the end of the staple-supporting strip I88. Just below the position where the staples enter the passage the sides of the widened portion thereof incline toward each other until the distance between them is but little greater than the length of the staple crossbar. The front and rear walls of the driver-guiding passage are spaced apart a distance substantially equal to the thickness of a single staple. The above-mentioned inwardly Inclined sides of the driver-guiding passage serve by engaging the lower ends of the legs of each staple fed into the passage, to maintain the staple in a position opposite the end of the strip I88 until it is forced downwardly by the descent of the staple driver. 1

A face on each staple" magazine |8| extends over the top of the staple-supporting strip I83 and serves to maintain the row of staples correctly seated on the supporting strip. It will be understood that there is no-separating member to separate from the row of staples a staple which is to be driven; the row of staples is simply pushed inwardly by pressure of the member I85 on its outer end until the leading staple is ar-'- rested by contact with the rear wall of the driverguiding passage in the path of the driver, the

latter being of such limited thickness as on its descent to engage only the crossbar of the leading staple. The staple-supporting strips I83 lead into the driver-guiding passages in such directions that the staples are fed into the passages with their crossbars extending widthwise of the machine or of the shoe. The strips associated with the driver-guiding tubes that are nearest the end of the toe of the shoe are moreover, inclined inwardly toward each other more than the strips associated with the other tubes, as indicated in Fig. 2, so that the crossbars of the staples when driven extend in substantially perpendicular relation to the inwardly curving side edges of the toe portion of the shoe bottom. The crossbars of all the staples, therefore, lie, when they are driven, transversely of the shoe in planes substantially perpendicular to the portions of the side edges of the shoe bottom that are nearest to them, so that the staple legs may reliably straddle the end portions of a binder wire applied around the toe end of the shoe in a manner now to be described.

It will be understood that the previously mentioned wipers 2| are arranged to wipe the marginal portion of the upper materials inwardlyagainst the lip of the insole around the toe and along the sides of the forepart after the last has been forced into the upper. The wipers 2| in the positioned by the operator in the groove in the wipers. Each gripper comprises a pair of gripping fingers or levers III, I I1 (Figs. 4, 5 and 8) extending laterally of the machine and freely pivoted between their opposite end portions on a vertical pin I I9, the two pins I I9 being secured in lugs projecting forwardly from the forward ends of carrier plates I20 to which the wipers are secured and by movements of which they are operated. Located between. the outer ends of each pair of gripping fingers is a compression spring I2 I which tends to urge their inner ends together so that the end of the binder wire may be gripped firmly between serrated Jaws provided on their inner ends. The outer end of each finger I I! has a tension spring I23 connected to it which pulls rearwardly on the finger and normally maintains its outer end portion in contact with a fixed vertical pin I25 on the machine frame, as shown in Fig. 4. As the wipers are moved forwardly and inwardly to operate on the upper, the outer ends of the fingers I I! are at first held against the fixed pins I23 by the springs I23 and the grippers, therefore, are swung about their pivot pins II9 which advance with the wipers. Accordingly the jaws on the inner ends of the fingers move forward more rapidly than the wipers and thus pull on the ends of the binder wire to draw it forwardly along the groove II I in the wipers and to pull it tightly around the upstanding marginal portion of the upper forced by the wipers against the lip of the insole. If the wipers continue their movements after the gripping fingers have drawn the wire tightly against the upper, the fingers are moved bodily with them, the outer ends of the fingers I I! being carried away from the pins I25 against the resistance of the springs I23 which are thereby rendered effective to pull the binder still more tightly against the upper, as shown in Fig. 5. This construction and arrangement permits the uppers of shoes of various sizes to be operated upon by the machine without the necessity of changing the wipers, the longitudinal tension applied to the binder wire by the grippers causing the wire to accommodate itself to the shape of the insole lip of each shoe operated upon and therefore to force the margin of the upper hard against the lip all around the portion of the shoe on which the wire acts.

Both the driver-guiding tubes 55 at each side of the shoe are arranged to be swung inwardly over the wipers toward the shoe by inward swinging movement of the bracket 29 associated therewith preparatory to the stapling of the binder wire to the shoe, the tubes being carried downwardly toward the bottom of the shoe during their inward swinging movements by reason of the position of the pivot 3| about which the bracket swings. To permit the lower ends of the tubes to be carried into positions for driving the staples in proper relation to the binder wire so as to fasten the wire firmly to the shoe, there are provided notches I21 in the edges of the wipers to receive the ends of the tubes. as shown in Figs. 4, 5 and 8, so that the lower ends of the tubes may descend into direct contact with the wire. The lower ends of the tubes have short depending lips I29 (Fig. 3) arranged to abut against the outer side of the wire at the end of the inward swinging movements of the tubes and thus to insure that the staples will straddle the wire correctly, the wire having already been pulled tightly against the upper. The portions of the wipers near their inner edges across which the lower ends of the tubes 5! swing in moving into their staple-inserting positions are beveled inwardly and downwardly toward the notches I21, so that the lower ends of the tubes may descend somewhat below the upper face of the wipers as they approach the shoe upper and the binder wire.

The driver-guiding tubes 35, urged downwardly by the springs II which act as described on the arms 5| connected to the tubes, would come into contact with and scrape across the upper face of the wipers soon after the beginning of the swinging movements of the brackets 29 if there were no means to prevent this. In order to avoid such wear on the tubes and the wipers as might result from this scraping action, there is provided means for preventing the lower ends of the tubes from coming into contact with the wipers until they have reached positions close to the edges of the wipers and are over the above-mentioned beveled portions. To this end, the adjustable stop screws I5 against which the two tube-supporting arms 5| at each side of the shoe are urged downwardly by the springs II are mounted in inwardly extending lugs I33 formed on an arm I34 (Fig. 1) which is fast on the previously mentioned rotatable pin 33, and there is also fast on this pin at its rear end an upwardly extending lever I35 provided at its upper end with a cam roll I38 in engagement with a stationary outwardly sloping cam member I31 fast on the machine head. As each bracket 29 swings downwardly and inwardly about its pivot 3I, the roll I36 is carried downwardly along the cam member I31 which accordingly acts on the lever I35 to swing the lugs I33 upwardly and thus to maintain the lower ends of the tubes 55 out of contact with the wipers until they are near the edges of the wipers. When the tubes reach these positions the roll I 36 leaves the cam member I31 and thus permits the tubes to be forced by the springs II downwardly against the beveled portions of the wipers, so that the lips I29 on the tubes can drop oif the inner edges of the wipers into the notches I21 outside of the binder wire, further downward and inward movements of the tubes being then stopped by the wire which is pressed downward and inward against the upper by the pressure of the tubes thereon.

The machine herein shown is further provided with a flexible clamping device I 39 (Figs. 2 and 4) which serves, similarly to the toe band shown in the previously mentioned Letters Patent, to wipe the upper upwardly about the toe end of the last in the downward .novement of the last and thereafter to clamp the upper against the last near the edge of the insole. As herein illustrated this device comprises a strip of leather I40 supported on a plurality of interconnected curved metal links arranged to extend along the edge of the shoe bottom. Pivotally connected together by a vertical pin I located beneath the meeting line of the wipers 2| are two links I43 curved to extend from the center of the extreme toe end of the shoe to points just beyond the corners of the toe, i. e., Jusbbeyond the localities where the curvature of the sides of the forepart merges with the curvature across the end of the toe. Connected by vertical pivots to the links I43 are comparatively long links I45 which extend approximately to the ball line of the shoe, and connected by vertical pivots to the links I45 are shorter links I41 which are curved to extend inwardly along the sides of the shoe beyond the ball line and somewhat beyond the portions of the wipers 2I that operate in effective wiping engagement with the upper. The pin i 4I that connects the links I53 is fixed against movement lengthwise of the shoe. The

forward ends of the links I41 have pivotally connected to them the forward ends of rearwardly extending horizontal toggle links I49 the rear ends of which are pivotally connected to other horizontal toggle links I5I mounted on fixed vertical pivots E53. Rearwardly extending horizontal links I55 are connected at their forward ends to the toggle links l5! by pivot pins I56, and the rear ends of these links I55 are connected to camoperated mechanism (not shown) by which, before the wipers 2I are operated to wipe the margin of the upper over the insole, straightening movements are imparted to the toggles M9, I5I. By such movements of the toggles the links I01 are swung inwardly toward the sides of the shoe and are also moved bodily in directions toward the heel end of the shoe to pull on the other links 8 43, I45 and cause them to close in tightly around the forepart of the shoe and thus to press the upper against and shape it to the sides of the last. By

' the construction shown the upper is accordingly shaped closely to the last by the clamping means from the end of the toe to locations somewhat at the rear of the ball line of the shoe where the sides of the shoe slope inwardly toward the waist portion and, as above explained, somewhat rearwardly of the locations where the wipers are effective on the upper.

The grippers 23 already referred to as utilized in place of the upper-clamping members H4 shown in the earlier Letters Patent are shown in Figs. 1 to 5, inclusive, and one of them with its controlling mechanism is also shown in greater detail in Fig. 9. Each gripper comprises an upper jaw I51 and a lower jaw I59 arranged to rest on the upper face of the underlying wiper ZI, the upper jaw being movable downwardly to grip the margin of the upper outspread upon the lower jaw. The two jaws are so controlled, as hereinafter explained, as to permit them to be pulled inwardly toward the sides of the last by the action of the upper thereon as the last is being forced downwardly into theupper and as the wipers H are advancing and closing 'over the insole. The lower jaw I59 is connected at its outer end by a pivot pin IBI to an upstanding bifurcated lever I 63 the lower end of which is mounted on fixed coaxial pivot pins of which one is shown at I65 in Figs. 1 and 9. The upper jaw I51 is pivoted at I61 to the lower jaw and has a curved tail piece I69 which is engaged by a roll I1I carried by a slide I12 movable inwardly and outwardly. along the lower jaw, theslide I12 being connected by a link I13 to the upper end of a second upstanding-bifurcated lever I15. The lever I15 carries about midway of its length a pin I11 the ends of which extend through slots I19 formed in bushings I80 that are freely rotatable in the lever I63, and by this means the lever I15 is supported on the lever I63 against downward movement. A pair of inwardly extending arms I8I formed on the bushings I80 carry between them a trunnion member I83 through i 5 which extends one end of a rod I85 the other end of which is secured to a member I81 embracing the pin I11. A spring I89 surrounding the rod I85 and hearing at its opposite ends on the members I83 and I81 normally positions the lever I15 in such relation to the lever I63 that the pin I11 is at the outer or right-hand ends (Fig. 9) of the slots I19. The lower bifurcated end of the lever I15 is connected by pivot pins I9I to links I93 (see also Fig. 2) which are pivotally connected to the upper end of one arm of a bell-crank lever I95. The two bellcrank levers I95 at the opposite sides of the structure are coupled together by a link I91. One of these bell-crank levers has a rod I99 connected to it through which operative movements are imparted to both the levers bycam-operated mechanism (not shown), this mechanism being maintained in its normal position by a spring When the upstanding arms of the bell-crank levers 595 are swung inwardly toward each other at the proper time in the cycle of the machine,-

the levers 515 are swungabout the pins I11 whereby they are fulcrumed on the levers I63, their upper ends moving outwardly and acting through the rolls ill to swing the upper gripper jaws l51 toward the lower jaws I59 to grip the upper. When the upper jaws have gripped the upper firmly, any continued swinging of the bellcrank levers H95 causes the levers I15 to swing about their connections with the links 913 by reason of the resistance of the gripped upper to their further swinging movements about the pins 511, and as the levers are thus swung about their connections with the links I13 the pins I11 are carried inwardly along the slots I19 against the resistances of the springs I89. Each lever I15 is further provided with an inwardly extending arm 2M to the inner end of which is pivoted a rod 203 which extends downwardly through a hole in a fixed lug 205 (Fig. 2). A spring 201 encircling this rod bears at its lower end against the lug 205 and at its upper end against a nut 209 adjustably threaded on the rod. The spring 201 accordingly tends at all times to swing the lever I15 in an outward direction about its connection with the link I93, and when the pin I11 is at the outer ends of the slots I19, as it is in-- itially, the spring 201 tends also to swing the lever- I63 outwardly through the action of the fulcrum pin I11 on this lever. Such outward swinging movements of both levers I15 and I63 are adjustably limited by a stop screw 208 which is threaded in an ear on the lever I63 and bears on a lug 209 (Fig. 2) on the head of the machine. By means of the screws 208 the opposite grip-- pers 23 may accordingly be adjusted toward and from each other. When the levers I15 have been swung to close the two grippers on the upper and the pins I11 have been carried inwardly away from the outer ends of the slots I19, as above described, the springs 201 still tend to impart outward swinging movements to the levers I15; and by reason of the connections established at this time through the closed gripper jaws between the upper ends of the levers I15 and the levers I63 springs 201 still tend also to force the levers I63 outwardly and maintain the screws 208 in contact with the lugs 209. It is accordingly against the resistance of the springs 201 that the grippers may be pulled inwardly toward each other by the upper in the manner previously described as the last is forced downwardly into the upper and as the wipers are thereafter closed inwardly over the insole.

ing instrumentalities further includes at each side thereof a shoe-upper positioning device by use of which insurance may be afforded that the upper is correctly positioned relatively to the means that operates thereon and relatively to the last positioned by the toe plate I3, the presser foot I5 and the toe-end abutment II. Each device comprises, as shown in Figs. 4, 5, and 10, a horizontal upperengaging member or plate 2 having a rear edge arranged to extend in a direction substantially perpendicular to the curvature of the edge of the last bottom in the region of the tip line of the upper. The member 2i I lies just above the upper face of the underlying wiper 2i, and when the parts are in starting positions its rear edge is close to the front side of the gripper I9. u The member is secured at its outer end to a forwardly extending threaded stem 2I3 mounted in bearings in a bracket 2 I 5 which is fixed to the forward end of the wiper-carrying plate I 20 that is located at the same side of the structure. 'The stem 2I3 is keyed to the bracket2i5 to maintain the member 2I'I in a fixed horizontal plane just above the plane of the wipers, and a nut 2i? threaded on the forward end of the stem and mounted within a bifurcated portion 2I9 of the bracket 2I5 may be rotated to adjust the member 2II forwardly and rearwardly for shoes of different sizes, the forward end of the stem being provided with graduations to facilitate the proper adjustment. On the rear edge of the member 2 there is an upstanding ridge 22I (Fig. 10) arranged to abut against the edge of the toe cap or tip of the shoe upper when the upper is pulled forwardly toward the operator. In order to hold the upper pressed downwardly against the member 2I I to insure proper contact between the ridge HI and the edge of the toe cap, there is provided over each member 2 a member 223. This member is secured at its outer end to a fixed portion 224 (Fig. 10) of the machine frame, and between its outer end and its inner end the member is formed as a fiat resilient strip which normally forces the inner end portion of the member down upon the underlying member 2i I. In order to lift the inner end of the member 223 so as to permit the margin of the upper to be inserted between it and the member 2| I, there is provided a rotatable cam member 225 in engagement with the lower face of the resilient strip portion of the member 223. The cam member 225 is formed on the rear end of a sleeve 22! (Figs. 4 and 5) which surrounds the stem 2I3, and clamped on the forward end of this sleeve is a short outwardly extending arm 229. The two arms 229 at the opposite sides of the structure are connected by cables 230 to a single treadle (not shown) by depression of which the sleeves 227 may be turned to lift the members 223 to receive the upper. The two members 2 may be so positioned that when the last is forced into the upper the tip line of the upper will extend across the last at right angles to the median line of the forepart of the last, thus insuring that the opposite ends of the tip line will lie at equal distances from the end of the toe of the finished shoe. Adjustment of the members 2II may be effected by the nuts 2 I 1 to determine with great precision the direction in which the tip line extends. It will be understood that by such adjustment the members 2 will not be carried away from beneath the members 223.

As above stated, the members M I are carried I by brackets 2|! which are secured to the wiper- In the machine herein shownthe set of operatcarrying plates I 20 and accordingly move with the wipers when the latter are operated, while the members 223 are secured to the frame and do not move with the wipers. As the wipers are operated, the members 2 are carried away from beneath the members 223, the upper having already been correctly positioned and having been thereafter firmly gripped by the grippers I9 and 23 and also clamped by the clamping-device I89. To permit the members 2i I to be returned to their initial positions beneath the members 222 in the return of the wipers to their starting positions, the forward ends of the members 223 are inclined upwardly so that the ridges 22! on the members 2 will pass readily beneath the members 223.

As previously stated, the staples are preferably formed of round wire, and as illustrated the legs of each staple in locations adjacent to the head or crossbar are separated from each other a distance less than the diameter of the binder wire. Since the legs normally diverge from each other, they readily straddle the binder wire when they are driven, and as they are forced into the work the portions of the legs near the crossbar bind against the sides of the wire, as shown in Fig. '7. and wedge it firmly against the work, the crossbar remaining actually out of contact with the wire at the end of the staple-driving operation. If the legs near the crossbar were separated from each other a distance as great as or greater than the diameter of the wire, it would be necessary, in order to secure the wire properly, that the staple be driven far enough into the work for the crossbar to bear firmly against the wire, which would necessitate a very precise adjustment of the length of stroke of the staple driver to insure that the crossbar would be forced with sufficient firmness against the wire without causing it either to shear through the wire or to be crushed against the latter. The use of staples formed as illustrated not only obviates the necessity for such precise adjustment of the stroke of the staple drivers, but also results in the holding of the binder wire more firmly against the upper than would ordinarily be the case if it were pressed against the upper merely by the crossbars of the staples. Since the staples are made of round wire of relatively small diameter, there is but little danger that the needle of the inseam-sewing machine, if it happens to strike a staple, will either break the latter or be broken by it. As illustrated, the work-penetrating ends of the stapie legs are blunt, so that the end portions of the 6 legs are more firmly gripped by the wood of the last than they would be if they were sharpened, and are also less likely be deflected out of their normal paths as they are driven into the work.

In the operation of the machine, the operator firsttakes a fiexible binder wire or hinder II3 which has been bent approximately to the shape of the toe portion of the lip of a welt shoe insole and tucks it into the groove III in the edges of the wipers 2I so that it lies somewhat back of the edges of the wipers, placing the end portions of the wire within the grippers H5, III which he opens by pressing on the outer ends of the fingers H5. The operator then depresses the treadle connected to the upper-clamping members 223 to lift these members away from the upper-positioning members 2, and presents a shoe upper, including a .toe box and a heel-end counter, upside down with the margin of the forepart of the upper outspread over the wipers 2| and with the portion of the margin around the extreme toe end extending beneath the clamp members I8. Portions of the margin of the upper located slightly nearer the end of the toe than the tip line are also presented between the open jaws of the grippers I9, and portions thereof located slightly nearer the toe than the ball line are presented between the open jawsof the grippers 23. As the upper is thus presented, portions of the margin located slightly farther from the end of the toe than the tip line lie between the members 2 and 223. The operator next releases the treadle that controls the members 223, whereupon these members by their resiliency press the upper down against the members 2| I. He then pulls the upper bodily toward him until such movement of the upper is arrested by contact of the ridges 22| on the members 2 with the edge of the toe cap at the opposite side margins of the upper. Having thus positioned the upper correctly in the machine the operator depresses the starting treadle to start the power operation of the machine. As more fully disclosed in the previously mentioned Letters Patent, the arm '8 is thereupon swung part way downward, carrying with it the pivoted block 9 on which are the toe plate 83 and the presser foot t5, the clamp members it are moved downwardly to clamp the upper against the wipers and the grippers W are closed on the upper. At substantially the same time also the grippers 23 are closed to grip the upper. At the conclusion of these several operations the machine comes automatically to a stop.

While the machine is thus at rest the operator takes a last having a welt shoe insole thereon and presents the last to the machine with the toe-end face of the last against the abutment I1 and the insole against the toe plate it and the presser foot l5, the toe plate fitting snugly against the inner side of the insole lip around the toe end and the presser foot i5 engaging the insole at the waist portion of the shoe between the portions of the lip located at the opposite sides of the insole.

Thereafter, while holding the last in the position thus determined, the operator pulls the heel end of the upper up into the correct position about the heel end of the last, and he then again depresses the starting treadle. The arm'l is thereupon swung farther downward and forces the last downward into the forepart of the upper, effecting at the same time an upwiping of the upper about the toe by the clamping device I39. As the last is thus forced downwardly, a pull heightwise of the last is exerted upon the upper by reason of the fact that its margin is clamped on the wipers by the clamp members I8 and is gripped by the grippers I9 and 23, the margin of the upper being partially withdrawn from between the clamp members and the wipers, and the grippers being pulled by the upper somewhat inwardly toward the sides of the last against the resistance of their controlling springs. In the course or the downward movement of the last, moreover, the pads 3 and 5 that underlie the last are depressed against the resistance of their supporting spring, and by reason of the yielding resistance of the'pads to the downward movement of the last the block 9 acts through the members I3, I5 and I1, in consequence of relative turning movement between the block and the arm I, to impart to the last a lengthwise movement forwardly toward the operator and thus to stretch the upper lengthwise, as fully described in the previously mentioned Letters Patent.

When the last arrives in its lowest position, in proper relation to the wipers 2| for the latter to wipe the margin of the upper materials inwardly over the insole, the pads 3 are inflated to press the upper closely against the sides of the last between the toe portion and the heel portion thereof. At substantially the same time the links I55 are operated and act through the toggles I49, |5| to close the forward links I41 of the clamping device I39 inwardly toward the sides 01 the shoe and to force them also toward the heel end of the shoe, thereby pulling the other links 3 and I45 more tightly about the forepart of the shoe, the links I41 acting to press the upper hard against the last in locations somewhat farther from the toe than the ball line. "As the machine continues its pperation, the wipers 2| are advanced and closed to wipe the margin of the upper materials over the feather and against the lip of the insole, the wipers at the same time carrying the binder wire H3 inwardly toward the lip. In this operation the wire is drawn tightly against the upstanding margin of the upper around the toe end and along the sides of the forepart by'reason of the fact that the portions of the spring-controlled grippers Hi5, iii which holdthe ends of the wire are advanced lengthwise oi the shoe faster than the wipers. In the course of the movement of the wipers the margin of the upper is drawn out from under the clamp members I8, and the grippers I9 and 23 are moved farther inwardly by the pull of the upper upon them. Substantially at the time whenv the wipers complete their inward wiping movement the clamp members I8 are lifted and the grippers l9 and 23 are opened and returned to their starting positions. While the wipers are then holding the upper pressed closely against the lip of the insole the arm I is raised a little to permit the spring which supports the pads 3 and 5 to press the shoe upward more firmly against the lower faces of the wipers.

While the upper is held as above described by the wipers and the binder wire, the swinging brackets 29 which carry the staple-inserting devices are swung downwardly and inwardly about their pivots 3| through. the rack and pinion mechanism hereinbefore described. When the I lower ends of the driver-guiding tubes 55 approach near the edges of the wipers, after having been held upwardly out of contact with the wipers by the stationary cam members I31, they are released by these members and are forced downwardly by the springs II into contact with the wipers. In their further inward movements they may then engage that portion of the margin of the upper that extends upwardly above the wipers and push it inwardly, the depending lips I29 at the lower ends of the tubes then coming into contact with the binder wire' lying against the margin of .the upper in the notches I21 at the edges of the wipers. By the lips I29 the tubes are accordingly positioned in the proper relation to the wire for the driving of the staples. The tubes, as they engage the wire, are carried inwardly out of contact with the wipers and are pressed downward in the notches I21 by the springs II so as to press the binder wire firmly down upon the margin of the upper over the feather of the insole. When the brackets 29 have finished their swinging movements, the pawls I00 are withdrawn from their holding relation to the arms 89, whereupon these varms are operated by the springs to impart to the staple drivers their stapledriving movements. It will be understood that tions of the legs and firmly held thereby against the upper at the end of the staple-driving operation. Two staples are thus driven at each side of the forepart, the positions of the staple-guiding tubes being such that in operating on a shoe of medium size the staple at each side which is nearer the end of the toe is driven in a location at or near the tip line, while the other staple at each side is driven in a location at or near the ball line. The staples, as willbe evident, are driven in directions inclined inwardly from the sides of the shoe and also forwardly toward the end of the toe.

After the staples have been driven as above described, the brackets 29 are swung outwardly to their starting positions by reverse movement of their operating mechanism. In such return movements of the brackets the cam rolls 536 are engaged by outwardly and upwardly sloping lower faces of the cam members 531, so that these members act to lift the arms 5! and the tubes 55. Since, however, the cam members are not immediately effective to lift the tubes out of the notches E2! in the wipers so as to clear the edges of the wipers, and since the tubes cannot swing outwardly with the brackets 29 until their lower ends are clear of the edges of the wipers, the springs 8! yield during the initial portion oi the outward swinging movements of the brackets and the tubes remain substantially stationary. As soon as the lower ends of the tubes are lifted above the wipers the springs 66 pull them outwardly into contact with the stop screws 63. The outward swinging movements of the brackets 29 serve through the rods 9| to lift the driver-operating arms 89 against the resistances of the springs 99 and to retract the staple drivers to their normal positions, the arms 89 being thereafter-retained in their upraised positions by the pawls H30.

After the staple-inserting devices have been returned to their starting positions the wipers 2! remain for a predetermined time in holding relation to the margin of the upper during a dwell in the cycle of operations of the machine, and then the machine is automatically started into operation again in the manner disclosed in the previously mentioned Letters Patent. As the wipers are retracted they leave the binder wire in upper-holding position. After the machine has finally come to a stop the operator releases the ends of the binder wire from the grippers ii 5, ill by opening these grippers, and then removes the shoe from the machine. Thereafter the shoe may, for example, be subjected successively to the operations of a heel-seat lasting machine and a combined welt-sewing and sidelasting machine, as further suggested in the above-mentioned Letters Patent.

Although, as above stated, the-inward movements of the staple-guiding tubes normally terminate with their lower ends in contact with the binder wire in the notches I21 at the edges of the wipers, it may happen that when the same wipers are used for lasting shoes of different sizes or styles the portions of the, wipers where the notches that are farthest from the end of the toe are located will under some conditions not press the upper closely inward against the lip of the insole. Under these conditions the stapleguiding tubes that are located farthest from the end of the toe may, upon contact with the binder wire, carry it inwardly beyond the edges of the wipers and force it firmly inward and downward against the marginal portion or the upper, at the same time acting through the binder wire to force these portions of the upper firmly against the feather and the lip of the insole. Substantial insurance is accordingly afiorded that even under these conditions the binder wire will be properly positioned and fastened to the shoe. Furthermore, as the grippers which grip the ends of the wire are carried outwardly away from the shoe by the opening movements ofthe wipers, they serve to bend the end portions of the wire more or less about the staples located substantially at the ball of the shoe and thus further insure that in case the staples have not been driven far enough into the shoe to grip the wire securely, the wire will nevertheless be held tightly against the upper around the forepart by the staples.
