Patented Sept. 5, 1916.

Application filed February 2, 1916. Serial No. 75,825.

Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Upper- Forming Machines, of which the following description, in connection with the accompanying drawings, is a specification, like referencecharacters on the drawings indicating like parts in the several figures.

This invention relates to upper shaping machines and isherein shown as embodied, for the purpose of explanation, in a machine of the type shown in my prior application, Ser. No. 728,183, filed Opt? 28, 1912, for shaping the assembled upper materials, including the heel stiflener, of the rear portion of a shoe.

The object of this present invention is to provide means by which to perfect the shaping of upper materials both as to the contour produced and as to'the permanence of the shape, whereby the subsequent lasting operation can be performed more expeditiously and also a more perfect product insured when the shoe is completed.

It is contemplated that some portions of this invention will be found to be also applicable to lasting machinery.

A very important feature of this invention consists in a molding machine having novel means for turning a sole attaching flange and shaping the flange. It has heretofore been proposed to turn a flange, either inwardly as in McKay and welt work or outwardly as in stitch-down work, and to shape it by pressure applied perpendicularly to the flange. In accordance with an important portion of this invention mechanism is provided to shape the flange by a plurality of rubbing movements directed alternately 1nwardly and then outwardly on the flange after the flange has been turned. It has heretofore been proposed to repeat flange turning movements by closing and then fully opening heel seat wipers an indefin1te plurality of times as set forth 1n United States Letters Patent No. 1,130,142, granted March 2, 1915, on application of James Cavanagh. The present invention is an im-- provement thereover inthat, among other things, the flange shaping and setting movements which follow the flange turning operation produce a square edge around the heel seat. -For this purpose the rubbing movements are preferably so limited in their backward stroke that the wipers do not uncover the line of bend but make short forward and backward rubbing strokes while remaining continuously in pressing engagement with the flange. As shown, the mechanism is constructed and arranged to effect automatically a plurality of short recipro-v cations of the flange setting means and at the will of the operator to make a full length stroke back to starting position.

A further feature of the invention consists in improved means for drawing out the stock of a sole attaching flange. The opera: tion of smoothly shaping an upper to either end portion of a last is largely concerned with redistributing the stock to transform a substantially straight sheet of material into a pocket-shaped heel or toe covering which shall be as free as possible from wrinkles and plaits. Ihave found that by repeatedly rubbing an inturned flange under pressure which increases as the rubbing proceeds inwardly the stock of the flange is extended or lengthened inwardly, or in the direction of the width of the flange, and simultaneously the wrinkles and plaits are smoothed out to a large extent so as to form,

for example, a satisfactory heel'seat. In the illustrated embodiment of the invention the increased pressure employed as the wipers advance is obtained, or is accentuated, by forming the seat face of an inside former in a plane at an angle to the plane in which the wipers move. The inside former is supported by a stiff spring which permits the former to yield downwardly. This movement of the former may advantageously be sufficient to cause it to travel down and up slightly in rubbing contact with the inner side of the upper, which is held by the outside former. This movement of the inside former eflects an ironing or smoothing and shaping of the foot engaging surface of the upper materials.

Another feature of the invention consists in novel outside forming means.

The foregoing and other features of the invention including certain combinations of parts and more important details of construction will now'be described in connection with the accompanying drawings and will then be pointed out in the claims, ex-

cept the novel method herein disclosed 119 which is claimed in co-pending application Ser. No. 62,041,'filed Nov. 17, 1915.

Fig. 2 is a vertical longitudinal section through apart of the machine and shows shoe upper materials being operated upon. Fig. 3 is a plan view on a larger scale in a plane below the heel seat wipers and above the outside formen' Fig. 4 shows the outside former in perspective view. Fig. 5 is, aplan view showing the inside former advanced to work receiving :position and illustrating the heel seat wiper operating mechanism. Fig. 6 is a perspec-,

tive view of the heel seat wiper operating mechanism. Fig. 7 is a sectional detail of the clutch of said operating mechanism.

' Fig. 8 is a plan view of the wiper mechanism.v

The illustrative machine has a driving shaft 1 continuously rotated from a pulley 2 and operating through speed reducing gears to turn the cam shaft 4. The shaft 4 has a cam operating through aswinging bar 5 and a link 6 and suitable adjustable connections to slide the work support horizontally between work receiving and work shaping positions in a guideway formed for it in the frame of the machine. support comprises a column 8 the foot of which has a horizontal bearing in the guideway of the machine frame and the upright portion of which has bearings for a two-part plunger 10 between the members of which is located a stiff compression spring 12. The upper end of the plunger 10 supports the inside former 15. This former has the general shape 'of the heel portion of a last, being somewhat narrower than the corresponding portion of the last and having its curvatures exaggerated for the purpose of overmolding the work in anticipation of more or less re-action of the molded work after it is withdrawn from the molding mechanism. A depending lug 14 is rigidly bolted to the front face of the former 15 and has a sliding fit in a portion of the column 8 to assist .in holding the former securely against angular movement relatively to the column 8.

For elevating the inside former there is provided in the frame of the machine a sliding member 16 supported by aQtoggle 17 which is arranged to be straightened by a connection with a lever 18 that is fulcrumed at 19 and has on its upper end a roll standing in a track of a cam on the'cam shaft 4. When the column 8 has been -moved to carry the inside former into position for the upper materials to be operated upon, the plunger 10 willbe over the sliding member 16 in position to be elevated by the straightening of the toggle 17.

side former which is shownin dotted lines in Fig. 1 and more fully in Figs. 2, 3 and 4 to comprise four sections including two front sections 25 and two rear sections 26 connected to the respective side sections by links 27. Each of the rear sections 26 is separately pivoted to the head of a plunger 28, the rear end of which slides in a. yoke 30. v The plunger isencircled by a 'spring""32 -which presses the former forwardly with relation to the yoke but allows it to yield backwardly to a limited extent as the inside former is drawn rearwardly into the outside former. A pin and slot connection between the yoke 30 and plunso ger 28 limits the forward movement effected by the spring 32. The yoke 30 has at opposite ends push bars 34, which act through yielding links 35 to press the end members 25 of the outside former forwardly and inwardly. The members of the plate of the machine, and the push bars 34 are guided against the lateral walls of said recess so that forward movement ofsaid push bars against the links .35 affects both a forward and an inward pressure upon the front ends of the formers 25. The former members 25 and 26 are also operated upon at the corners of the heel by spring plungers 36, 37 which are carried in blocks 38 that are movable in arc-shaped guideways 39 formed in the lower face of the recess that contains the outside formers. The cross-head 30 is operated by a rod 40 that is connected with one member of a toggle 42, see Fig. 1. A link 43 depending from the toggle carries a roll running in 10 opening and slightly retracting the members of the outside former for receiving w the work and for reversely moving them to embrace shoe upper materials carried by the inside former after said former has been drawn into the machine. The outside former isshown as provided with a continuous lining 45 that bridges the joint; 1 tough hard sole leather has been found to make a good lining for the outside former. The hning is confined in place by supporting-clips 46, Fig. 4, applied to the lower 2 sides of members 25 and by spring clips 48 mounted on the frontends of the former members 25. These clips permit the slight relative longitudinal movement that occurs between the lining and the members of the former as the former is opened'and closed and maintains the lining seated against the 'rear members 26 of the former.

In addition to the outside former above described the machine is provided with tends around the rear portion of the heel.

The plate 50 is mounted on a slide bar 52 and a spring 54 holds it normally pressed forward beyond the adjacent portion of the outside former as shown in Fig. 2.

The head plate of the machine frame is provided with bearings for heel seat wipers which are overlapped and confined against upward displacement by a cap plate 62. The wipers may be of any suitable construction but are preferably of the two-part type shown in my prior application Ser. N 0. 36,736, filed June 28, 1915 in which their construction is claimed. It is sufficient here to describe that each wiper comprises a rear end member indicated at 60 in Figs. 2 and 5 and a side member 64. The rear member 60 is provided with a cam slot in which stands a stationary stud as shown by dotted lines in Fig. 5. The outer edge of member 60 is curved in an arc and bears against an edge wall of the recess in which the wipers slide. Each wiper member 60 is connected by a link to the cross-head of an operatingrod 65. The described arrangement is such that the wiper member 60 receives, in response to the forward movement of the rod 65, a combined advancing and closing movement over the rear end of the heel seat. The side member 64 has a sliding connection with the rear end member by which the member 64 is caused to partake of the closing movement of member 60. A fixed stud 66, however, projects into a transverse slot in the member 62, restrainingmember 64 from partaking of the advancing movement of the member 60 and causing its acting edge to swing inwardly and backwardly over the shank and the front part of the heel seat.

For operating the wipers the rod 65'is connected with a strap that embraces an eccentric 72 which is loose on a counter-shaft 75. The counter-shaft is not dependent upon the cam shaft 4 but is continuously operated by a bevel gear connection from the main driving shaft 1 as shown in Fig. 1. l A clutch shown in Figs. 6 and 7 is arranged to cause the eccentric to be'operated from the counter-shaft 75. The clutch comprises a sleeve 76 pinned to the shaft and pro.- vided on its interior surface with shoulders adapted to be engaged by a clutch bolt 78 carried by the hub of the eccentric, when the bolt is turned by its spring 79 into a position to project tangentially from said hub. The clutch bolt has an upstanding stud 80 which is adapted to be engaged by a clutch con-' of position for engagement with the shoulders 0n the sleeve 76. The clutch controller is carried by a lever 84 the front end of which is in position to be engaged by a plate 85 carried by a vertical bar 86, the lower end of which has a connection, shown in Fig. 1, with a roll standing in a track in the side face of a cam carried on the cam shaft 4.

The operation of the cam shaft is controlled by a starting treadle through a suitable one-revolution clutch and brake mechanism described in my prior applica tion Ser. No. 728,183. 7

The described arrangement is such that when the cam shaft is started in response to pressure on treadle 90 the column 8, carrying the inside former 15 with-the work arranged around it, and preferably held under tension longitudinally of the shoe, is drawn back into the outside former, engaging first with the plate 50 to press the upper materials inwardly or forwardly at and adjacent .to the upper edge of. the heel stiffenen' After the inside former has been seated back against the outside former the. inside former is elevated by straightening of toggle 17 and then the outside former is closed by the straightening of its toggle 42 after which the slide bar 86 is drawn downwardly to rocklever 84 and release the clutch bolt 8 that controls the 'countershaft 75. Thereupon the eccentric 72 commences to turn and the wipers are closed for bending the margin of the upper materials inwardly over the heel seat face of former 15 for turning the soleattaching flange of the upper. The clutch controlled by the starting treadle 9O is so constructed and arranged as to bring I the cam shaft automatically to rest with the work clamped between the inside and outside formers and with the inside former upraised. The cam track operating the slide 86 is so formed that the slide and its plate 85 are in lowered position when the cam shaft comes to rest and therefore the clutch controller 84 is upraised leaving'the wiper reciprocating mechanism in continuous operation by reason of its direct COIlIlGCtlOIl to' the driving shaft 1. 0

The wipers make their flange turning movement, by which they bend the margin of the upper materials over the heel. seat face of the former, from a fully retracted position. The connemion between the operating rod 65 and the eccentric strap 70' preferably comprises a lost motion whlch,

when operative, causes a shortening of the backward movement of the wipers so that they are not fully withdrawn from over the heel seat but their movement terminates with the edge of the wipers inside the edge of the rear end of the heel seat. For the purpose of obtaining this lost motion the rod 65 has a sliding engagement with its bearing 92 in the eccentric strap member and is provided with adjustable stop nuts 93 and a collar 94 spaced apart a distance greater than the length of the bearing 92. From the collar 94 projects laterally a stud "95 adapted to be engaged by an upwardly faced hook 96 that is carried by the bearing 92. The hook 96 is provided with a laterally projecting stud which extends under the plate 85, previously identified, and

when the plate .85 is lowered it engages the stud on hook 96 and disengages'the hook from stud 95 and holds it out of engagement with the stud during thenperiod in which the cam shaft is at rest; :,While the hook is held depressed the lost motion between the bearings 92 and the-nuts 93"is operative so that the backward movement of the wipers is shortened to terminate inside the edge of the heel seat as above described; This arrangement provides for giving to the wipers a short reciprocation continuously in contact with the heel seat flange for repeatedly rubbing the flange'first inwardly and. then outwardly. When it is desired to discontinue the rubbing of the flange the starting treadle 90 'is again depressed whereupon the cam controlling ele-' vation of the -inside former. depresses'the former to relieve drag of the wipers over the shaped flangeand the cam controlling the slide bar and plate85 effects a lifting of the, plate 85, thereby releasing the book 96 and allowing it to reengage the stud 95 so that at the next complete rotation of the counter-shaft 75 the wipers will be fully retracted for uncovering the work. Elevation of plate 85 also releases lever 84 whereupon the controller 82 will operate the clutch bolt 78 to discontinue wiper movement with the wipers fully retracted. Also projection thereof above the tread face ofthe inside former 15 so that a sole attach- -ing flange of the desired width will be produced by the operation of the machine. The

' the inside former.

height gage is herein shown as mounted on a fixed portion of the machine frame in position to be over the rear edge of the inside former when said former occupies its work receiving position, Fig. 1. The gage is pivoted to adapt it to be swung backwardly by the operator to get it out of the way when he is putting the upper materials around The gage swings back into operative position by gravity as soon as it is free to do so. The inside former will preferably be maintained hot by an 9 electric heating unit so that the upper materials are subjected to the action of heat while they are being shaped, it being found by experience that the application of heat to the upper materials facilitates the successful "operation of the shaping means on the work.

In the use of the machine the upper materials, properly prepared and assembled together and usually including a heel stiffener, are passed rearwardly over the inside for mer 15 when the former occupies the posi-; tion shown in Fig? 1, the gage 97 being readily pressed back out of the way' by the turned for drawing the inside former into the outside former, then elevating the inside former, and then closing the outside former to jack the shoe. It may be here stated that vertical movement of the inside former is not absolutely essential and good results can beobtained inthis machine without. the

use of the elevating mechanism. The stop clutch controlled by the treadle brings the cam shaft to rest with the work under shaping pressure but before this occurs the rotation of the cam shaft acts through the slide 86 and connected parts to close that clutch which connects the continuously running shaft 75 with the wiper, and it isthe movement of the eccentric 72 on said shaft which effects the advance of the wipers to turn in the heel seat flange. The plate 85 on the slide 86 continues the clutch closed while the cam shaft is at rest so that the wipers are reciprocated repeatedly and effect a multitude of outward andinward rubbing movements over the inturned flange; The plate 85 on the slide 86 also holds'the hook 96, Fig. 6, out of engagement with the plunger 65 and thereby renders operative the lost motion between the plunger and the eccentric 72. This lost motion shortens the outward movement of the wipers over the heel seat flange and causes that movement to terminate inside the edge of the rear end of the heel seat so that during their repeated rubbing movements over the flange the wipers remain in continuous shaping engagement with the flange. The wipers 64 effect, in their closing movement, a gathering of the stock from the forepart of the heel and from the shank inwardly and slightly backwardly and then in their repeated movements the wipers operate'to effect the shaping of this rearwardly gathered stock into the'heelseat flange. This serves to hold the sides of the upper close together-at the shank.

As the wipers advance in their closing movement they move inwardly over an incline 98 on the rear end of the tread face of the inside former, traveling in a plane slightly inclined therefore to the underlying portion of the flange supporting surface, and are caused to bite into' the stock of the flange and rub it in a manner to reduce its.

thickness and extend the width of the flange inwardly. As the wipers ride inwardly over the incline on the inside former the former is slightly depressed, the spring 12 yielding to permit such action, andwhen the wipers move outwardly, the spring returns the former to elevated position as far as permitted by the controlling member 14. This action of thev wipers therefore produces a short up and down movementof the inside former within the upper and in rubbing engagement with the inner face of the upper materials. This movement of the former effects a smoothing and shaping of the inner face of the upper materials, and each time the former rises it applies molding pressure to the upper materials at and adjacentto the line on which the flange was turned in wardly.

The operator uses his judgment as to the length of time during which the work should be subjected to the repeated rubbing movements of the shaping instrumentalities and then again depresses the treadle 90. This results in the rotation of the cam shaft to elevate the slide 86 and allowthe hook 96 to reengage the plunger 65 preparatory to making a complete retraction of the wipers to their starting position. The elevation of the slide 86 also allows the wiper clutch to be opened at the next complete rotation of the shaft, the said clutch being arranged, of course, to be opened at the end of the retraction of the wipers. The rotation of the cam shaft unjacks the shoe and restores all of the upper shaping instrumentalities to then starting positions, returning theinside former to the position shown in Fig. 1'pre paratory to the removal of the shaped upper therefrom and the application of a fresh piece of work.
