OUTSOLE TRIMMING AND CHANNELING MACHINE.`

Application led August 1, 1913.

To atl 'Lo/0m it may concern i "le it known that I, FELIX E. VALois, a citizen of the United States, residing at Haverhill, county of Essex, State of Massachusetts, have invented a certain ne and useful Improvement in Outsole Trimming and Channeling Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to that class of machines which are employed in boot and slice factories to trim olf the protruding edge of the outsole of a boot or shoe while on the last, and to cut the groove or channel in which the stitching is laid. The machine is employed in the manufacture of welt shoes and is of the type ordinarily known as a rough rounder and channeler but the devices hereinafter' described improve the operation of theinachine to such an extent Ithat a relatively smooth edge is pro` duced and therefore the machine is not properly termed. a rough rounder.

Herctofore, in machines of this class so far as known to me it has been customary to employ an automatic feed mechanism by which the work is advanced at a predetermined rate of speed to the trimming and channeling knives. The `speed of the feed depends solely on the speed at which the machine is run and the operator has no control over it except by changing the speed of rotation of the machine. It results therefore that the mach-ine is speeded to feed the shoeforwardat a rate which will enable a poor or slow workman to use it and a rapid andskilled workman can do no more work on it than a slow workman. In the machine embodying my invention no feeding means is employed, and the operator feeds the shoe through the machine by hand, 'at whatever speed he finds convenient. It therefore results that the machine is adapted for use by both rapid and slow workmen without any change or modificationand; inpractice it is found possible to run the machine at a speed far in excess of that of any `(rt-her machine of this type, so far as known to me. `lt is also particularly adapted to difficult work`r because the workman may feed the shoe as slowly as is neces Specification of Letters Patent.

controlV of the operator, but without requiring special attention or care on his part. No adjustment is required for different sizes of slices, except that the position of the socalledlinger grips on the flexible connection will ordinarily be varied according to the different sizes of shoes.

The machine automatically forms an edge having anamount of Baltimore which is proportioned to the length of the edge to which `it is applied. i

The mechanism described herein by means of which the production of the Baltimore edge is controlled by the operator is believed to be wholly novel, andto be applicable to various `kinds of machines, such for instance as outsole sewing machines for guiding the working instrumentalities thereof.` Therefore in the succeeding claims I have claimed it broadly and independently of ther working `instrumentalities of the outsole trimming machine shown and described herein.

During its passage through the machine vents the shoe being fed forward so fast that the trimming knife will skip, since the feed stop and guide will not permit the shoe to be fed farther than the end of the preceding cutinadc by the trimming knife, and therefore makes `it possible to feed the work by hand instead of by automatic feed- ,ing mechanism, ashas heretofore ordinarily been done. Since the shoe is guided by the feed stop and guide which engages the edge ofthe sole as well as by the crease guide which rests on the upper, no bunch or ir` regularity is made in the sole when the operating instrumentalities pass by the seam of the tip.` T believe that the feed stop and guide is also capable of useful apq'ilicationy to nuichines having automatic feeds. While I have described the machine embodying` my invention as constructed without an automatic feed, I do not limit myself to this construction as an automatic feed may be easily applied to the machine and will in no way interfere with the operation of the other parts of the machine. As automatic feeds areold and well known in the shoe machinery art, it has not been thought necessary to show or describe the same in detail in the present specification.

The trimming knife is given an exceedingly rapid reciprocation and therefore makes a great many more cuts for a given distance than machines of this kind have ordinarily made and by this means the edge of the sole is trimmed vperfectly smooth.

In the machine shown in the drawings herein, the channel knife and hammer are withdrawn to enable the operator to insert or remove the work by the action of a pedal and the position of the channel knife relatively to the edge of the outsole as well as the position of the trimming knife during the operation on the shank and the produc tion of a Scotch edge are both controlled by another pedal, but the two pedals are not in use simultaneously, and therefore may both be conveniently operated by the workmans left foot.

In the drawings, Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is a front elevation of the machine. Fig. 3 is a top plan view. Fig. -e is a side view of the crease-guide, hammer, channel knife, trimming knife, and feed stop and guide showing the relative position of the various parts during the operation upon a shoe. Fig. 5 is a view of the working instrumentalities of the machine. In this View the machine is about to begin to trim the shank of a right shoe, having just completed the production of the Baltimore edge. Fig. 6 is a detail of the channel knife actuating mechanism. Fig. 7 is a section on line 7 7 Fig. 3 looking in the direction of the arrows. Fig. 8 is a detail showing the relations between the trimming knife and hammer. Fig. 9 is a view of 'a modification showing mechanism for moving the feed stop and guide during the trimming of the sole.

The principal working instrumentalities of the machine consist in the trimming knife 11, which trims the edge of the sole, the channel knife 12 which cuts the channel in the bottom of the shoe; the anvil 13 (see Fig. 2) against which the trimming knife operates; the hammer 14- by means of which .the stock is held stationary during the cutting movement of the channel knife, and the welt and sole are compressed and flattened; the feed stop and guide 15 (see Fig. 2) the functions of which are hereinafter fully set forth; and the crease guide 16 by the movements of which the width of the edge of the shoe is determined.

To enable the following description to be more readily understood the operation of the working instrumentalities 'of the ma- L11/asse chine will be shortly outlined. The shoe is inserted between the crease guide 16, the anvil 13 and the hammer 14, and then the hammer' advances and clamps and compresses or beats the sole and welt against the crease guide. The hammer then remains stationary in this position momentarily. During this time, the channel knife 12 makes its cutting movement by swinging in a horizontal plane. At the same time, the trimming knife 11 makes a cut through the edge of the sole. lVhen the hammer has moved back and released the work the operator moves it forward for a short distance limited by the feed stop and guide 15. The shoe rests against the crease guide 16 at the cutting point and the newly trimmed edge engages the under side of the feed stop and guide 15 while the upper side of said feed stop and guide is engaged by the under edge of the trimmings. The width of the edge is controlled by the crease guide 16 which rests against the upper, therefore as the shoe is filled by the last, the shape of the edge of the shoe is determined by the shape of the last. In the machines shown herein, the formation of the Baltimore edge isalso controlled by the position of the crease guide 16. As long as the crease guide 16 remains stationary, an edge of even width z'. e. Scotch edge is formed, but if the crease guide is pushed down gradually a Baltimore edge is produced. The crease guide is moved by a treadle to produce the Scotch edge and to produce the Baltimore edge it is moved by a train of mechanism actuated by a chain to which is attached a finger grip or medal which is seized by the hand of the operator and held firmly against the bottom of the shoe so that as the shoe progresses through the machine, the chain or other flexible member is pulled out and the crease guide given a corresponding movement up or down as the case may be, thereby varying,

the width of edge and forming the Balti more edge.

rllhe anvil 13 is secured to the frame A of the machine and is stationary and rigid and affords a bearing against which the trimming knife cuts.

At B is shown the driving shaft of the machine. On the shaft B is an eccentric 17 surrounded by an eccentric strap 18. The eccentric strap 18 is forked at its forward end, as is shown in Fig. 3, the two fork members being designated 181 and 182 respectively. y y

The hammer 1&1 is pushed forward against the work by the member 182, there being a heavy spring 19 interposed so that when the pressure exerted on the work by the hammer reaches a predetermined amount, the spring will yield and injury will not be done to the work, nor will the machine be strained; The eccentric strap actuates the trimming knife 11, being; pivotally secured to it by a pin 22 which extends through both members of the work. The trimming knife 1l is secured by the bolt 20 to the forward end of the knife bar Q1, being adjustable thereon by means of the said bolt 20.

The knife bar 21 is not notched on the side `next the hammer, as shown at a, and the said notch is engaged by a projection Y) on the adjacent side of the hammer 14. The length of the projection b is less than the length of the notch a, and the spring 19 which is interposed between the fork member 182 and the hammer 14: holds the ham' mer in its extreme forward position with the shoulder of the projection l against the forward end of the notch a except when the nose of the han'nner is in contact with the sole of the shoe, at which time the hammer is pushed back for al distance determined by the thickness of the stock. From the fore-` going it will be seen that the trimming knife and the hammer reciprocate together', except for the relative motion occurring just as the trimming knife passes through the stock, during which time thc hammer is stationary and clamps the stock firmly against the crease guide 16. l

The trimming knife bar 21 carries on its underside a stud 23 for a cam roll 241A. `This cam roll 2d actuates the channel knife bar holder and the channel knife bar in the following manner: The channel. knife bar 25, to which the channel knife 12 is adjustably secured by the screw 36, is mounted on. a lever .27 which for convenience l callthe channel `knife bar holder. Said channel knife bary 25 issupported on the holder by means of a horizontal pivot 2S for a purpose to be hereinafter more fully explained.

The holder 2T has an arm c extending rearwardly, which is pi'votcd at to the frame of the machine, and on which the holder is swung by the movement of the trin'nning knife. Secured to the top of the knife bar holder 27 is a plate 30, see also Fig. 7, in which is a cam groove 31. `The cam roll 524i, secured to the under side of the trimming knife bar movesfin the cam groove 31 and as the trimming knife bar 21 moves forward and back the holder 97 and consequently the channel knife bar 25. is swung about the pivot 29 thereby giving' to the channel knife the properly timed movement in a horizontal plane to cut the channel. The cutting movement of the channel. knife l'. c. the .movement toward the right as seen` in Fig. 6, is timed to occur while the trimming knife is making its cut and the stock is held stationary between the nose of the hammer 14- and the crease guide 16.

The channel knife 12 is raised and lowered to vary the position of the channel with regard to the edge of the shoe in the following manner: As previously s .ated

the channel. knife bar 25 is supported in the knife bar `holder 27 on the horizontal pivot f2.8. The groove (Z in the knife bar holder `within which the channel knife bar holder received is deep enough to allow the channel knife bar to swing in a vertical plane the requisite amount. The downward movement of the knife is limited by an adjustable stop which consists of a bolt 301 in a lug .32 on the front end of the channel knife bar holder. The lock nut` 33 serves to render permanent the adjustment of the bolt 530.1. 'lo the rear end of the channel knife bar 25 is secured a link Bil which .is itself also secured lto the treadle connection 255 operated by a `trcadle 6G which l call the control treadle. To permit the channel knife bar `to swing the requisite amount, the rear edge of the plate 30 is cut away on the under side as shown at Elli. rl"he rear end of the channel knife bar is engaged by a spring 3T which tends to hold thcknife bar down on the stop bolt 301., so that when the parts are in their normal position c. at rest, the channel knife is in its lowest position `and which is the position which it occupies when operating upon the shank of thc shoe where it is desirable to have thc channel cut at a distance from thc edge of the shoeto enable the outsole sewing machine to operate successfully. .As the operator moves the shoe through themachini and reaches the point between thc ball and the shank he depresscs the treadle and this brings the channel knife bar to the edge of the shoe so that from` then on the channel is cut in proper `position around the sole of the shoe. Then the knife again reachcsthc point between the ball and the shank thctreadlc is .re-` leased so that along the shank the channel is cut at a distance from the edge of the shoe. The spring l? jjrreviously referred to also tends to hold thc channel knife bar` as far forward as possible so that the knife will cut the channel to the full depth for which the knife set. The depth of the channel is varied by changing the position of the knife 12 on the knife bar 25 b v means of the screw 2G. The tension on thc spring 37 is adjustable by means of the adjusting screw 91 having its head on the hack side of the machine.

To permit the hammer 14 and the channel. knife 12 to bc drawn back to allow the insertion of the work, the following 1ncchanism isprovidcd: At 3S is shown a .rock shaft provided. with rearwardly extending lever 39 to which is attached the treadlc crmncction -Il-O operated by a treadle 67 which .may be termed the starting treadle. The rock shaft 38 is provided with two fingers 41 and 42. lVhen the lstarting treadle is pressed down the finger 4].. en-

gages a small pin 43 ou the side of the churn;

nel lmife bar and slides the channel knife bar back on the pivot 2S, which is in a slot 44 in the channel knife bar. The channel knife bar is held back as long as the treadle is depressed. rock shaft 38 contacts with the mushroom head of snap pin 40. The inner end of said snap pin 46 at times enters a shallow groove 47 in the side of the hammer 14. When the starting treadle is depressed, the finger 42 moves out of engagement with the mushroom head 45 of the snap pin 40 so that the pin snaps into the groove in the hammer when the hammer is next drawn back by the eccentric strap. rlhereafter and as long as the starting treadle is depressed the ha-.nmer cannot move forward beyond a predetermined position because the end of the snap pin engages the rear end of the groove 47. As soon as the starting treadle 67 is released, a spring 48 restores the finger 42 to its original position and pulls out the snap pin 4G so that thereafter the hammer may move forward and engage the work.

T he mechanism by which the position of the shoe relatively to that of the trimming knife is varied and by which the width of the edge z'. c. the Scotch edgeof Baltimore edge is produced, will now be described.

it 15 is shown a stationary member which l term for convenience the feed stop and guide. This feed stop and guide is secured to the frame of the machine and is adjustable vertically by means of the screws 49 so that its position although normally stationary maybe changed slightly as required. The feed stop and guide 15, see particularly Fig. 5 has a .horizontal finger which is conveniently eval in cross section and engages the underside of the trimmings which is cut olf by the trimming knife. It also preferably engages the trimmed edge of the shoe and is located as close as possible to the trimming knife 11. At 16 is shown the vertically movable crease guide, the face f of which rests against the upper on the last. I term this member for convenience the crease guide but it will be understood that it may rest against the upper in which case it might be termed the last guide. From Figs. 2 and it will be seen that the crease guide 16 is slotted and surrounds the anvil 13, being guided between the head of the machine, which is shown at A. and a front plate 51 secnred to the head. The crease guide 16 is normally held in its highest position by means of a spring 52 contained in a hole in the plate 51 and engaging a lug on the top of the crease guide` The upward movement of the crease guide is limited by a stop bolt 54 in a lug 55 on the head A of the machine, the usual locknut 56 being provided.'-0n the back of the crease guide 16 is a stud 57 on which is a roll 58,

rlhe other finger 42 on` the 1,11a,eee

60, the rear end Vof which passes through a hole 62 in the frame of the machine, said hole being enlarged to permit the front end of the shaft 60 to be raised and lowered without binding. At 63 is shown a slide pin the lower end of which rests on the shaft 60. The forward end of a pressing lever 64 rests on the upper end of the pin 63 while the rear end of the pressing lever is pivoted at G5 to the frame of the machine. The pressing lever 64 is moved down when required by the operator by means of the contro-l treadle 66 and link 67. The treadle 66 is the one previously described which controls the vertical position of the channel knife 12. A spring G8 is interposed between the link 67 and the pressing lever 64 so that after the pressing lever has reached the limit of its downward movement, the treadle may continue to move the rear end of the channel knife down.

0n the shaft 60 is located a small rimmed pulley 69 around which is wrapped a chain or other flexible connection 70. The two ends 701 and 702 -of the flexible connections pass over a two-grooved pulley 71 which is mounted on a stud 72 on a boss on the front corner of the cover 7 3 which serves in part to guide the hammer 14. The two ends 701 and 702 of the flexible member pass through a hole 704 in the front end of the channel knife lbar and have secured to them two finger grips or medals 7 5 and 76 respectively. The'finger grip 75 is marked L and the grip 76 is marked R to indicate which grip is to be used on the right shoe and which on the left. lThe hole 74 in the channel knife bar 25 is of oval cross section as is seen in Fig. 1, and is flared somewhat on the left hand side of the channel bar, as is seen in Fig. 2. lt is also divided by a small partition 92, said partition being located near the right hand side face of the channel knife bar. The grips or medals are each tapered slightly as shown at g and are of such a size that they may enter the flaring hole 74 for a. short distance. Therefore whenever the operator draws one finger grip away from the hole 7 4 and the other finger grip is drawn back into the flaring hole 74, the grip 'will be in vertical position with its flat face substantially parallel to the sole of the shoe and closely adjacent to it, so that the workman may conveniently seize the finger grip with its fore finger holding the fingerl grip against the bottom of the shoe. The parts 1 Ier treadle, as frequently happens.

' out with the shoe and the cam shaft 60 will be rotated an amount determined by the length of the flexible connection. The length of the flexible connection may be ad- `justed by some suitable means as for instance by the thumb screw 93 which moves the sleeve 94 on which the two-grooved pulley 7l is mounted. The rotation of the cam shaft in one direction pushes down the cam roll 58 and therefore the crease guide 16 and increases the Width of the edge left on the sole by the trimmingknife. The rotation of the camshaft 60 in the other direction allows the crease guide 1G to be raised by the spring 52 and therefore the width of Ithe edge is progressively diminished.

f The grips `75 and 7 6 arepreferably conf cave on both` sides and are also knurled or roughened at h. as Will be seen in FigpZ so that the operator may hold the grip `immovably in place against the sole of the shoe.

As Will be seen from the drawings, the cam roll 58 is located beneaththe cam 59 and when the pressing lever G4 :is at its lowest position the collar 80 so stops its further movement and supports the pressure of the operators foot in case he stands on the This arrangement is a great advantagebecause there can never be any undue pressure put on the cam shaft 60 or intermediate parts.`

The collar 80 is adjustable vertically on the pin 63 which is screw threaded there being a set screw 95 to hold it in place when once adjusted. The position of this collar determines the width of the Scotch edge. .Also it starts the next shoe in the right position to begin the Baltimore edge having` finished the Baltimore edge on the preceding shoe.

At 110 is shown heating means asa gas burner by means of which the crease guide 16 may be heated to iron the portion of the upper with which it contacts. Small wrinkles frequently occur at the toe and elsewhere whichmay be thus ironed out easily especially iftheshoe is not fed forward too fast or if it is drawn back and fed forward once or twice as may be easily done since the feeding is done by hand.

The operation of my machine is as foll lows Assuming that the right shoe is the lirst one to be trimmed, the machine begins at the heel end of the inside of the shank, works along the shank, then along the inside of the ball, then around the toe along the outside of theball, and finally along the shank to its heel end. The machine is then in position to `begin the operation `on the left shoe. This takes place in the reverse order. To insert the work the operator depresses the channel knife bar 25 by the action of the `linger lll which engages the pin 'till The depression of the treadle also allows thesnap pin i6 to catch the hammer l.l on its next backward movement and prevents the hann'ner advancing while the` work is being put in place. The work is then inserted with the upper at the heel end of the shank, against the crease guide 16, the welt and sole being on the back side of the crease guide lll and the anvil 13. The starting trcadle is then released. The hammer` let-compresses the welt and sole against` the anvil. and clamps the work in stationaryV position. lVhile the shoe is stationary the channel knife moves horizontally and makes y the firstcut of the channel which. isat a distance from the edge of the shank. At the same timethe trimming knife cuts through the edge of the sole. 'lhe next rotation of the machine withdraws the trimming knife and the hammer so that the operator can feed the shoe forward. `He `then moves the shoe forward for a distance depending on his skill` and the character of the work, but which is less than the width of the`trim ming knife, since the feed stopyand guide prevents it being advanced farther.' This feed nlovcment which in the machine shown in the drawings is produced Wholly by hand, takes place while the channel knife is swinging back to its original position preparatory to making the next cut. After the shoe has been fed forward the hammer and trimming knife again ad ance and the channel knife makes the succeeding cut, this cyele.of movement being rapidly repeated. As soon as the first cut has been made the feed stop and guide passes into the space between the trimmings and the edge of the sole and thereafter thefeed stop and guide plays an important part in the guiding of the fed too fast. The feed stop and guide and the crease form two points of support `for the work, the former being stationary and the latter being movable. `While the feed of this shoe forward as herein described, is a step-bystep motion it is in actual operai tion apparently continuous, because the ma-y chine makes a very quick succession of move ments, and the work is fed forwardbvhand at substantially a uniform rate. l lt may be stopped at any` point withoutnjury tothe work and may be advanced slowly or rapidly without producing anappreciable difference in the quality of the work. When the working instrumcntalities have reached the end of the shank which isalso the beginning of the ball, the operator depresscs the other treadle 6G, and thisraises the channel knife 1l, swinging it on thepivot 28, and brings the channel closer to `theedge ofthe sole. The depression ofthe treaclle shoe as well as by preventing it being iso l l pressed as the shoeis advancing. The op also pulls down the presser' lever 64 and the pin 63 until the collar 80 strikes the top of the head. rlhis swings down the end of the cam shaft 60 and lowers the crease guide against the pressure of the spring 52 for an amount determined by the position of the collar 80. Thereafter, as long as the lparts remain in the position described the trimming knife will sever the sole at a uniform distance from the upper and will form the so-called Scotch edge along the inside balland toe of the shoe, to the point where the Baltimore edge is to begin. The transition from the shank edge to the Scotch edge will be gradual because the treadle is deerator then continues to advance the shoe,

' swinging it properly to trim the toe of the shoe and to form a Scotch edge around the toe. If no Baltimore edge is to be formed on thev shoe the treadle is held down until the beginning of the shank is reached on the outside of the shoe when the treadle is released and the parts return to the shank trimmingl position as seen in Fig. 5. If a Baltimore edge is to be formed on the shoe', thefollowing operation occurs. As soon as the operator has turned the toe of the shoe, he seizes the medal marker R, which is the medal then in horizontal position, with one end in the hole 74. The operator then holds the medal firmlyv against the toe of the shoe with his forefinger as is indicated in Fig. 5, and continues to feed the shoe forward until the beginning of the shank is reached. The movement of the shoe from the toe to the beginning of the shank draws out the flexible connection 70, revolves the cam 59, and progressively depresses the crease guide for an amount determined by the shape of the cam. rlhis operation continues until the end of the flexible connection is reached because the other medal has brought up against the socket in the channel knife bar. The operator then releases the treadle and the shank trimming operation takes place 4in the usual manner, completing the operation on the right shoe.

It will be seen that when the right shoe is trimmed the parts are left with the cam in the position which it occupies at the end of the formation of the Baltimore edge. rlhis is the correct position to begin the formation of the Baltimore edge on the left shoe, this shoe being trimmed in the reverse direction. It' will therefore be seen that the machine is particularly adapted to trim rights and lefts alternately but that if circum# stances require a succession of rights or lefts they can. be trimmed by pulling the proper medal out after each shoe is trimmed to restore the cam 59 to the proper starting position.

The amount of Baltimore edge given to the shoe is determined by the shape of the cam. The particular shape of the Baltimore edge is also determined by the slope of the cam. If a gradual Baltimore edge is re-k quired the cam will be given a substantially uniform slope7 but it may be given an abrupt f slope at any point where it is desired to form a relatively large Baltimore edge. The mechanism described forms the Baltimore edge in proportion to the length of the flexible connection which is pulled out. Thus if the cam gives a Baltimore edge of a quarter of an inch on a shoe in which the Baltimore edge extends for a distance of four inches along the edge of the sole, it will give a Baltimore edge of three-quarters of a quarter inch on a shoe having a Baltimore edge eX- tending along three vinches of the sole. By this means the amount of the Baltimore edge is proportioned to the length of the sole.

In Fig. 9 there is shown a modification of my invention. In this form the feed stop and guide 111 is-vertically movable bymeans of the two treadles 112 and 113, and the chains 114 and 115. 4 The extreme top and bottom positions areadj usted by screw stops 116 and 117, and the springs `11S and 119` tend to hold the feed stop in its central position. By this arrangement the Baltimore edge may be produced Ieven if the crease guide is held stationary, since the feed stop and guide will then be slightly higher or lower than the trimming knife and each cut will therefore be slightly above or below the preceding cut.
