SOLE LAYING ANDROUNDI'NG MACHINE:

iSPEGIFiCATION forming part of Letters Patent No. 698,257, dated April 22, 1902.

Application filed November 23, 190i). Serial N 0. 37,413- (No model.)

To all whom it may concern: 1 Be it known that I, WALTER H.- CLARK, a

citizen'of the United States, residing at North Marshfield, county of Plymouth, State of Massachusetts, have inventedan Improvementin Sole Laying and Rounding Machines, of which the following description, in connection with the accompanying drawings, is aspecification, like numerals on the drawings representing like parts. I

This invention relates to shoe machinery;

. and it comprises a machine capable of performing the functions ordinarily accom plished by a sole-molding machine, a solerounding machine, a sole-laying machine;

and a channeling-machinep It is the common practice in the manufacture of shoes to round or shape the sole of the shoe according to a certain patternand mold the same between dies to give it the proper shape before it is applied to the shoe.

This necessitates handling the sole-blank several times in putting it through'the various operations and also necessitates several diEerent types of machines.

It is the object of my invention to provide a single machine which will mold the sole to the last by pressing the sole-blank between a former and the last, and this operation also results in laying the sole or attaching it to the shoe. For this purpose both the soleblank and the shoe have applied to their coni tacting faces a coating of suitable adhesive,

and the pressure employed in pressing the sole-blank between the former and last al'so serves to attach said sole-blank to the shoe.

While the sole-blank is thus clamped be-' tween the former and the last on the jack, the sole is rounded or shaped to the last, and

to accomplish this I provide my machine with a suitable knife, mounted on a carriage,'and

suitable mechanismis provided for causing the knife-carriage to travel around theshoe, the knifebeingguided in its movement by and means to bring the former and last to gether, so that a sole-blank may be placed on the former and clamped between thesame and the-shoe on the last, to thereby mold the sole-blank and at the same time attach it to the shoe, combinedwith a knife-carriage having yieldinglymounted thereon a knife to cut the sole to the proper shape, and means 'to guide the knife in its movement, so that it will follow the shape of the last. I have therefore provided a single machine by means of which a sole can be molded, attached to the shoe, rounded, and channeled in asingle series'of operationsand without any handling of the sole. I can therefore dispense with the various different machines now used for these various operations and substitute therefor my sin'gle'machine.

Figure 1 shows in elevation my improved machine. Fig. 2 is an end view thereof. Fig.

3 is a planview. Fig. lis a section on the line a; m, Fig. 1. I Fig. 5 is a detail showing the clutch-operating mechanism. Figs. 6, 7, and 8 are views of the knife-carriage. Fig. 9 is a detail showing the guide-plate for the knife-carriage. Fig. 10 shows the formers, and Fig. 11 is a detail hereinafter described.

The frame of the machine is designated by 3, and this may be of any suitable construction, it having at its upper end the guides 4:, on which the former 5 and its support is mounted for vertical movement, as hereinafter described.

The upper ends of the guides 4 have mounted'thereo'n' the cross-head 6, which supports the heel and toe pieces 7 and 8 of the jack, as usual in devices of, this class. In this con struction, however, instead of having the jack rigidly carried by the cross-head I have supported the same yieldingly thereon, the heel and toe pieces 7and 8 of the jack having their'shanks mounted fervertical sliding movement in holders 9 10, which holders have ahorizontal sliding movement in

slots

11 and 12 in said cross-head.

The-purpose of mounting the

holders

9 and 10 in slots is so that the distance between the position, the adjusting device'in this instance being shown as a suitable pivotally-mounted disk 13, having the links 14 pivotally connected thereto and to the

holders

9 and 10. By turning the disk 13 by means of the thumbpiece 15 it will be obvious that the distance between the heel and toe pieces of the jack may be varied at will.

Coiled springs 16 surround the shanks of the heel and toe pieces, the said springs abutting at one end against a shoulder 17 on said shanks and at the other end against the holder through which the shanks of the heel and toe pieces of the jack pass.

Suitable means made rigid with the upper ends of the heel and toe pieces of the jacksuch, for instance, as pins 1Sserve to hold the said heel and toe pieces in the

holders

9 and 10.

From the above description it will be seen that my jack is mounted for vertical movement in the cross-head 6 and has a yielding connection therewith, the purpose of which will be hereinafter described, the springs serving to normally hold the jack in its lowermost position, but allowing it to yield when pressure is applied thereto. In this embodiment of my invention the former is rigidly mounted on a vertically-moving support and is held against motion relative to the support, and suitable means are provided for raising and lowering the former, whereby a soleblank may be placed on the former when in its lowermost position and the former then carried up against the last, clamping the sole between the same and the last and at the same time molding the sole to fit the last. The support for the former is designated by 20, and the former is shown at 5 and has its upper face properly shaped to form one of the die members for molding the sole-blank, the last acting as the opposing die member, as stated above. Preferably the working face of the former-has a facing of rubber or other yielding material 5, from becoming bruised in the molding. The support 20 has the lugs 22, which aresleeved over the uprights 4, by means of which construction the support and former are properly guided in their vertical movements. As shown, the support 20 has rising therefrom and rigidly secured thereto pillars or posts 27 28, on which is fixedly mounted a plate 29, forming part of the guideway for the knifecarriage, as hereinafter described, the said plate having rigid and preferably integral therewith the lugs 30 31, on which the former 5 is supported.

As seen in Fig. 10 and in dotted lines in Fig. 9, the former has approximately the which prevents the sole from the lugs 30 31, whereby either a right or left former may be used. One convenient way of accomplishing this is to make the upper ends of the lugs 30 31 with square portions 31, which set into suitable sockets in the bottom of the former, as seen in dotted lines in Fig. 1, though I wish it understood that any other suitable way of detachably securing the former to its support may be employed, if desired.

The former and its support are given their vertical movement by means of eccentrics 35, mounted on the counter-shaft 36, the links 34, connected to the eccentric-straps, being pivotally connected to the support 20. (See Fig. 1.) The counter-shaft 3G is geared to the main shaft 39 by means of the gears 40 41, which are fast on the counter and main shafts, respectively, and, as seen in Figs. 2 and 4, the gear 41 on the main shaft is one-half the size of the gear 40 on the counter-shaft, wherebya complete rotation of the main shaft will turn the counter-shaft 36 through onehalf a rotation. The main shaft 39 is driven by means of the continuously-running beltpulley 37, which is loosely mounted upon the said shaft, suitable clutch mechanism operating to clutch the pulley to the shaft when it is desired to rotate the same. The clutch comprises the collar 43, having the clutch projections 44 on one face, which cooperate with corresponding recesses on the hub of the driving-pulley 37, the said collar 43 being feathered to the shaft 39, and the spring 49, which surrounds the shaft 39, and is confined between a portion of the frame and said collar, tends to throw the clutch members into engagement. The collar 43, which constitutes the movable clutch member,is normally held out of engagement with the pulley 37 by means of cam-lug 45, integral with said colcollar, which is engaged by an offset arm 48, connected to an actuating-lever 46, pivotally mounted in any suitable way to the frame, as at 47. When the lever 46 is depressed by any suitable means, the offset arm 48 is disengaged from the cam-lug 45,when the spring 49,which surrounds the shaft 39, operates to give the collar a longitudinal movement, thereby cansing the engagement of the clutch projections and the consequent rotation of the shaft 39. l Vhen the main shaft has made a complete revolution and the counter-shaft consequently a half-revolution, the cam-lug 45, moving in the direction of the arrow in Fig. 5, contacts with the inside of the offset arm 48, and thereby moves the collar 43 longitudinally on the shaft, compresses the spring 49, and disengages the clutch members. Asuitable spring, such as 50, serves to raise the operating-lever 46, after the same has been depressed, sufficiently to bring the offset arm 48 into the path of the cam-lug 45. t

As illustrated in the drawings, the offset arm 43 is mounted upon a separate lever 51, which is pivotally mounted on the frame, and the said lever is connected by means of a link ICC 6 tach the same to the shoe.- In order to prevent Q r the former is beingraise d' to '"lay the'sole', l'

have provided suitable clamping-mechanism between the cross-head and the guides 4, which clutch mechanism which may be thrown-into operation by simply depressingva lever and which is automatically disengaged when the counter-shaft has made a half-revolution.

The cross-head 6 is also mountedfor vertical motion on the guides 4, the downward mo tion of the cross-head being, givento the same by the rods 60,conneetedto fears 38 at the: ends of said cross he'ad and also connected to the cross-piece 61, the said cross-piece being operated by means of the foot-lever 62, which is connected thereto by the link 63. The upward motion of "the cross-head is de- ,rived from the springs 64, whi'chsurround the guides '4 and abut atone end against collars or similar abutments 65, fixed on the rods,- and at their other end against the under side of the cross-head 6;

The operation of'the parts thus far" 'de-' scribed is as follows: A last'having a shoe lasted thereon, to which shoe an insole is at-;

tached, as shown at 66 in Fig. l, is'placed on the jack and a sole-blank 170, which has not been either molded or roun'ded', is placed ontheformer 5, thesole-blank and the bottom of the shoe both havinga coating of suitable'adhesive applied thereto, as usual, and

the former and shoe are then brought to-' gether and sufficient pressure-applied to mold the sole and attach it to the shoe by the same operation. This is accomplished by first depressing the-lever 62, which through the links operate to depress the cross-head 6, and thereby bring theshoe on the jack in contact with the former 5. Thelever 46 is then depressed, allowing the spring 49 to cause the clutch'members to engage, whereby the shaft '36 is given a half-rotation, asabove described, and the support 20, and consequently the former-5, is raised to its extremevupper position, this operation causing the jack with the last applied thereto to yield vertically against the action of'the springs'l6, I would herere-v mark that the'said springs 16 areof su lficient strength so that the pressure applied to the sole through the jack is'suftlcient to mold'the same to the proper shape and toproperly atthe cross-head (i from yield'ingupward while clamping mechanismisfso eonstru'cted'as to admit of a free down-wardmovement" of v the cross-head,butto automaticallylock the cross- ['65 head from upward motion As shown in Fig. 1, the links 60 areattached tothe ears 38 on th'e' sleeves 70, which surround the upper influence of the springs 64 when it is desired terns corresponding to the various sizes and to'accomplish this-I claim the same broadly.

'to the shape of the last is accomplishedis' as to the-directionjof movement of thecarriage,

"erating means for thecarriage comprises the ends of the guides 4, the sleeves '70 being in: I tegral with the cross-head '6, as seen in Fig. 11. Each sleeve isprovidedwith a radial slot 69, in which is pivotally mounted a spring pressedfriction-dog"71, having a nose-72, which bites against the guide 4, and thus prevents the sleeve from moving upward, but allows the free downwardmovement thereof." 7

By releasing the nose 72 by means of'thel v handle on the lever it willbe evident that the cross-head can move upwardunder the to remove the shoe frorn'the-jack. While the 80. Y shoe is pressed against thefornier to thereby mold the sole-blank and attach the'sanie'to the shoe, a suitable knife isthrownin oper ation to round the sole,the knife moving completely around the shoe'and being guided 83 I I in its movements by the last, whereby-the knife operates to round the sole to the shape of' the last. At the'same'time that theisole isrounded a channeling-knife operates tocut- I the'usual channel in the bottom of 'the sole. 9o. Heretofore one common practice has been to round the soletoa pattern before'thesame s I is applied to the shoe; but this'pra'ctice has I necessitated the use'ofright-and-left patv shapes of lasts. With'my mechanism,'where in the rounding of the soleis accomplished I while the sole is clamped'between theformer and the shoe,the sole is rounded to the shape o of the last and no patterns are lrequiredfroo This'I regard as an important feature of "my I invention, and as I believe thatI am thefirst' 1 The means whereby this roundingof'the sole I I follows: A suitable guide-plate 23,-having lugs 24, which are'sleeved OVerFthQuprights' 4, is carried by the-'support2Qfor the fqrmer, v

and the said guide-plate 23 has a" suitable I central opening which contains the 'i'plate'29', above described, the plate 219; and innerwall of the openingin the guid'e plateg23 forming between them a guideway 84 for the knifecarriage 105, presently to be-describedJ As seen in Fig. 9, thisguideway 84 has the generalshapeof a shoe sole, but' is so coni I structed thatit can be used"in"roundihgf I either right or left soles, The carriage 105, on which: is .ryieldably supported; a knife, rests on the guideE- plate 231andis moved around the shoe'by mechanism herein-after described,ithe said carriage being guidedfinitsj movement by the guideway 84, while the knife, which is'supportedon said carriage 'forslid ing movementin adirection atright angles -1 2'5 is guided b'yithe last,andfits movementflo erates to out or round the sole to the sha 'of the last, as hereinafter'described'. I 'Iheop- "1 3 sprocket-chain'85,arranged onth'e under side J I of thetplat'e 23 andcarryingsuitable lugs 86, 1"

which'pass upthrough the guideway84 and" o r f areguided'in'their{movement thereby, the I lugs having attached thereto the carriage 105 for the knife. The sprocket chain passes around the sprocket-Wheels 88, which are mounted for turning movement upon the posts 27 28, which connect the plate 29to the support 20. One of the sprocket-wheels 88 has integral therewith a bevel-gear 80, meshing with bevel-gear 90 on the short shaft 91, suitablyjournaled on the support 20, and the said shaft carries at its outer end a bevel-gear 92, which meshes with a corresponding gear 93 on the vertical shaft 9 1, the said shaft 91 being geared to the driving-shaft 95 by a suitable system of gearing, such gearing in this embodiment of myinvention being shown as a bevel-gear 96 on the lower end of shaft 94, which meshes with a corresponding gear at the end of a short counter-shaft 07, suitably journaled in the frame ries at one end the bevel-gear 98,which meshes in turn with the gear 99, fast on the shaft05. A loose driving-pulley 100 is carried by the shaft 95 and is adapted to be clutched thereto by any suitable clutch mechanism ,such clutch mechanism being shown in Fig. l as a friction-clutch 101. A rock-shaft 103, suitably mounted on the frame of the machine, has at one end the fork 101, which engages a groove in the movable clutch member, and the said rock-shaft carries at its opposite end the treadle 102, by means of-which the clutch members can be brought into engagement. Any suitable means (not shown) may be employed to cause the disengagement of the clutch when the said treadle is released. With the driving mechanism thus described it will be obvious that whenever the clutch 101 is thrown into engagement the sprocket-wheels 88 will be revolved,thereby carrying the knifecarriage around the shoe, this movement of the knife-carriage operating to both round the sole and to channel the same, as hereinafter described.

In order to allow of the requisite vertical movement of the former-support 20, I make the shaft 9a a two-part shaft, the upper part 90' telescoping in the lower part 04, this arrangemeut allowing the support with the gearing thereon to be raised or lowered without breaking the operative connection between the drive-shaft and the sprocket-chain. The two parts of the

shaft

90 and 91 may be connected together in any suitable way, so that the rotation of the shaft 91 will drive 90', and, as illustrated, the shaft 00' carries the pin 91, which plays in a slot 92" in the shaft 94:.

By this construction the two parts of the shaft 'inay have arelative longitudinal movement,

but are locked togetherso as to rotate in unison.

Referring now to Figs. 6, 7, and 8, which show in detail a suitable form of sole rounding and channeling mechanism, 105 is the carriage to which the posts or lugs 80, carried by the sprocket-chain 85, are rigidly connected, the said carriage being supported for sliding movement on the top of the guide- The shaft 97 carplate 23 and being guided in its movement by the guideWay-S L, as previously explained. This carriage 105 has yieldably mounted thereon both a rounding-knife and a channeling-knife, and for this purpose it is provided with a suitable guideway 100, in which is mounted for sliding movement in a direction radial to the path of travel of the carriage a spring-pressed slide 100, the said slide having the flanges 177, which play in suitable grooves in the base 105 (see Fig. 8) and being held in its operative position by means of the springs 121, which are fast at one end to the base 105 of the carriage and at the other end to the slide. (See Fig. 7.) The inner end of the slide carries a suitable knife 107, provided with a cutting edge 107, the said knife having a limited turning motion about a vertical axis in order that the knife may accommodate itself to the curvature of the sole as the carriage passes around the shoe. As illustrated, the knife-head 108 has the cylindrical projection 109, which sets in a suitable socketin the slide 100, as shown in dotted lines in Fig. 8, and the said projection 109 has a radially-projecting pin 111 screwed therein, which pin projects through and plays in a slot 110.in the slide 106, this pin serving to limit the turning motion of the knife, as will be obvious, and also preventing the knife from being withdrawn.

In order to support the under side of the sole as the knife is traveling around the same, I have provided the guide-support 113, this being shown in the nature of a block having the projection 114, seated in a suitable recess in the slide 100, and preferably I employ a spring 115 in the bottom of the recess, which serves to maintain the guide-support against the under side of the solo. The guide 113 carries at its upper end the roll 116, which bears against the under side of the sole and serves to support the same as it is being cut into shape. As stated above, the last operates as a pattern-surface to give the proper shape to the sole, and this is accomplished by means of a guide-Wheel 117, which is mounted for turning movement upon an arm 118, pivotally mounted, as at 119, on the slide 100. A suitable spring serves to hold the lever 118 in its operative position. Referring to Fig. 6, it will be seen that the said guidewheel is cone-shaped, and in operation the conical surface thereof rests on the top of the sole, while the base of the cone abuts against the shoe on the last, the springs 121 serving to hold the guide-wheel in constant contact with the shoe as the carriage is propelled around the shoe. i

The dotted lines in Fig. 6 show the position of the sole and shoe-upper relative to the knife-carriage, and, as illustrated, the sole during the rounding process rests upon the guide-1011116, and the spring 120 serves to clamp the sole between the guide-wheel 117 and the guide-roll. Suitable guides 123 rising from the slide 100 and disposed on oppo- IIO site sides of the lever 118 serve to hold the said lever against lateral movement.

From the above description it will be seen that as the clutch 101 is thrownin operation the bevel gear-wheel S9'will be driven through the mechanism above described to thereby rotate the sprocket-wheels and sprocket-chain 85, the said sprocket-chain, through the lugs 86, propelling the knife-carriage around the shoe and the guideway 84 guiding the carriage in its movement. The knife 107 being carried on the slide 106 has a movement independent from the carriage, and, as stated above, the springs 121 serveto keep the slide toward the inner end of the carriage, and thus maintain the constant contact of the guidewheel 117 with the shoe-upper on the last, and hence as the knife-carriage travels around the shoe the guide-wheel follows exactly the shape of the last, and therefore gives to the slide 106, upon which the knife 107 is mounted, requisite movement relative to the carriage to round the sole exactly to the shape of the last. With my machine, therefore, it is not necessary to provide special patternsurfaces or templets for use in rounding the sole, as the last itself performs this function. Then the knife-carriage has passed completely around the shoe, the foot-treadle 102 may be released to cause the disengagement of the clutch members 100 101, and thereby stop the movement of the knife-carriage.

In placing a shoe upon the jack or removing it therefrom and in placing the sole-blank upon the former it is necessary to move the knife and guide-wheel out of the way of the sole, and this is accomplished by means of the lever 130, which is pivoted at one end to the knife-carriage, as at 131, and bears intermediate its length against the uprights 132, to which the lever 118 is pivoted. By moving the lever to the right in Fig. 'Zit will be evident that the slide 106 will be retracted against the action of the springs 121, thereby way of the shoeor its sole.

screw 133.

Any suitable means may be employed to hold the lever in its retracted position, and

in Figs. 6 and 7 I have illustrated the springcatch 133, which engages the lever and holds it retracted. I have also provided means whereby the sole is channeled at the same time that it is rounded, this being done by the channeling-knife 134, which is also yieldably supported on the carriage, preferably by mounting it upon the guide-support 113, which-is supported on the slide 106. purpose the said guide-support has the ofiset portion 135, in which the shank 136 of the said channeling-knife is adj ustably mounted and held in its adjusted position by the set- The knife will of course be so adjusted that its cutting edge 138 will be slightly above the top of the roll 116, and, as illustrated, the outside edge of the knife is in substantially the'same plane as the cutting edge of the rounding-knife 107, whereby the chanthe slot 141 in the slide 106.

For this nel will be cut in the sole from the outside edge thereof.

It is essential that the channeling-knife have a slight turning movement on a vertical axis to accommodate itself to the turning movement of the knife-carriage in passing around the sole, and this may be accomplished in any suitable way. As illustrated, the shank 114 of the guide-support 113 is provided with a radially-projecting pin 140, which plays in The slot is slightly wider than the pin, thus allowing for the necessary turning movement of the channeling-knife. It will be obvious, of course, that other ways of providing for this turning movement may be usedinstead of that shown.

As stated above, the jack which supports the last is yieldingly mounted, this construction being made necessary, because'in using the knife carriage in connection with the former for rounding the sole it is necessary that the former and knife have a definite relative position to each other, and therefore instead of making the former yieldinglymounted I have made my jack vertically yieldable. From the above description it will be seen that I have combined in a single machine mechanism which is adapted to mold a soleblank between the former and a last and at the same time attach the same to the shoe, and while the sole is thus clamped between the former and shoe mechanism is set in operation which rounds the sole, using the last as a pattern.

' Simultaneously with the rounding of the sole the sole is channeled, and all these operations are performed upon the shoe without taking the same from the machine.

Various modifications may be made in the structure of my device without departing from the spirit of the invention, and I therefore reserve the right to make such changes as come within the scope of the claims.
