Definitions

  • This invention relates to machines for use in the manufacture of boots and shoes and more particularly welted shoes, and it has for its object to provide means for removing surplus material at and adjacent to the rear ends of the welt and inseam.
  • An important feature ofthe invention consists in welt butting means constructed and arranged to be actuated transversely of the shoe for cutting the welt edgewise.
  • a further feature of the invention consists in means for holding the welt while it is being cut.
  • the holding means will comprise one or more clamping members for restraining the welt from displacement during the cutting operation.
  • holding means herein shown includes a member for yieldingly clamping the welt in the direction of the thickness of the welt while the knife is actuated in the direction of the width of the welt.
  • the illustrated machine is also provided with means for engaging shoe stock, at the inner edge of the welt while the cutter advances from the outer edge of the welt.
  • a further feature of the invention consists in a novel construction and arrangement of means for cutting the stitches and severing from the shoe bottom surplus stock to present a suitably even seat for the heel end of the outer sole.
  • cutter can be, and as herein shown are, formed as a single knife having an angular cutting edge.
  • a guard which shields the upper from injury by the cutters during their operation and protects the knife from engagement by the shoe while the latter is being positioned.
  • the guard is movable from a retracted position in which the placing of the shoe is conveniently effected into a position in the welt crease between the knife and the upper on the side edge of the shoe.
  • the guard plate determines the relation of the cutters to the bottom of the shoe.
  • the knife may conveniently be arranged to have sliding contact with the upper face of the guard.
  • the guard will be advanced manually from its retracted position to engagement with the shoe so that it can be correctly positioned in the welt crease without liability of injuring the shoe.
  • the cutters will preferably be actuated by power driven mecha nism.
  • a single manually controlled device with which the guards on the two sides of the machine are yieldingly connected is also operatively connected with the power mechanism for starting the latter by a continued movement.
  • the guard and the cutters are therefore caused to operate successively through the instrumentality of a single manually controlled means, the cutters being advanced and then retracted automatically by the power driven mechanism when the latter is rendered operative.
  • the guard is arranged for movement vertically to find automatically the level of the welt crease of the shoe which is in the machine, and the knife rests upon the guard so that the cutters are automatically positioned vertically for the height of each shoe.
  • the guard also serves as a presser for pushing the shoe stock inwardly to tighten the upper over the edge of the last and po sition the welt transversely of the shoe bottom. It is frequently found that the end portion of the welt is bent outwardly and the guard and presser force it into normal relation to the shoe bottom and to. the path of the cutter and hold it while it is being beveled.
  • Another feature of the invention consists in means for clearing from the shoe the surplus stock, including the severed butt end of the welt and any other material that may be cut oil by the knife.
  • the invention is shown as applied to a machine for tightening over a last the shoe stock at and adjacent to the rear ends of the welt, positioning the upper, counter and welt ends correctly and holding these parts of the shoe while the welt butts are cut off and the parts fastened by tacks and com pressed to level the heel portion of the shoe bottom preparatory to the sole laying operation.

  • the actuation of the driving shaft when the clutch is operated turns the shaft 85 and the crank 84 thereon to communicate motion to the last supporting spindle for raising the shoe against the wipers 60, whereby the shoe stock engaged by said pressers is compressed and leveled down upon the shoe bottom to form a seat for the outersole.
  • the spring 68 permits the abutment or bottom rest 66 to yield during the compressing operation so that the entire compressing force is received by the wipers 60.
  • the shaft 85 carries also a cam 140 for actuating a rod 142 that extends to a tack separating and delivering mechanism supported on the head of-the column.

ARTHUR L. RUSSELL, OF HYDE PARK, MASSACHUSETTS, ASSIGNO-R TO UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.
MACHINE FOR USE IN THE MANUFACTURE OF BOOTS AND SHOES.
To all whom it may concern:
Be it known that I, ARTHUR L. RUSSELL, a citizen of the United States, residing at Hyde Park, in the county of Norfolk and Commonwealth of Massachusetts, have invented certain Improvements in Machines for Use in the Manufacture of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.
This invention relates to machines for use in the manufacture of boots and shoes and more particularly welted shoes, and it has for its object to provide means for removing surplus material at and adjacent to the rear ends of the welt and inseam.
An important feature ofthe invention consists in welt butting means constructed and arranged to be actuated transversely of the shoe for cutting the welt edgewise.
A further feature of the invention consists in means for holding the welt while it is being cut. Preferably the holding means will comprise one or more clamping members for restraining the welt from displacement during the cutting operation. holding means herein shown includes a member for yieldingly clamping the welt in the direction of the thickness of the welt while the knife is actuated in the direction of the width of the welt. The illustrated machine is also provided with means for engaging shoe stock, at the inner edge of the welt while the cutter advances from the outer edge of the welt.
It frequently happens that the welt attaching stitches of. the inseam extend back of the point at which the welt is cut ofi or beveled and it is necessary to sever the stitches which connect the butt end before the surplus stock can be removed from the shoe.
A further feature of the invention consists in a novel construction and arrangement of means for cutting the stitches and severing from the shoe bottom surplus stock to present a suitably even seat for the heel end of the outer sole.
The welt beveling cutter and the stitch Specification of Letters Patent.

cutter can be, and as herein shown are, formed as a single knife having an angular cutting edge. Cooperating with the cutters is a guard which shields the upper from injury by the cutters during their operation and protects the knife from engagement by the shoe while the latter is being positioned. Preferably the guard is movable from a retracted position in which the placing of the shoe is conveniently effected into a position in the welt crease between the knife and the upper on the side edge of the shoe. The guard plate determines the relation of the cutters to the bottom of the shoe. The knife may conveniently be arranged to have sliding contact with the upper face of the guard. Preferably the guard will be advanced manually from its retracted position to engagement with the shoe so that it can be correctly positioned in the welt crease without liability of injuring the shoe. The cutters will preferably be actuated by power driven mecha nism. As herein shown a single manually controlled device with which the guards on the two sides of the machine are yieldingly connected is also operatively connected with the power mechanism for starting the latter by a continued movement. The guard and the cutters are therefore caused to operate successively through the instrumentality of a single manually controlled means, the cutters being advanced and then retracted automatically by the power driven mechanism when the latter is rendered operative. The guard is arranged for movement vertically to find automatically the level of the welt crease of the shoe which is in the machine, and the knife rests upon the guard so that the cutters are automatically positioned vertically for the height of each shoe. The guard also serves as a presser for pushing the shoe stock inwardly to tighten the upper over the edge of the last and po sition the welt transversely of the shoe bottom. It is frequently found that the end portion of the welt is bent outwardly and the guard and presser force it into normal relation to the shoe bottom and to. the path of the cutter and hold it while it is being beveled.
Another feature of the invention consists in means for clearing from the shoe the surplus stock, including the severed butt end of the welt and any other material that may be cut oil by the knife.
ills herein shown the device hereinbefore referred to as engaging the stock at. the inner side of the welt to hold it during the cutting operation. is arranged for moven'ient; outwardly to clear or drag away from the shoe bottom the surplus stock which has been cut oil". This leaves the shoe free and clear to receive the outersole.
The invention is shown as applied to a machine for tightening over a last the shoe stock at and adjacent to the rear ends of the welt, positioning the upper, counter and welt ends correctly and holding these parts of the shoe while the welt butts are cut off and the parts fastened by tacks and com pressed to level the heel portion of the shoe bottom preparatory to the sole laying operation.
Certain features of the invention are to be found in the combinations. which will be described. of the positioning. holding, securing and leveling means with the welt butting and stitc cutting means.
Other features of the invention, including certain details of constriiiction and combinations of parts will be explained in connec- 5 tion with the following description of a preferred construction embodying the invention and will then be particularly pointed out in the claims.
Figure 1 of the drawings is a side elevation of the machine; Fig. 2 is a perspective view shmving many of the operating parts; Fig. 3 is a transverse section showing parts pzn'ticnlarly concerned with this invention; Fig. 1 is a perspective view of the stitch cutting and welt butting and removing devices; Fig. 5 is a plan view of the knife; Fig. 6 is a perspective view of the rear portion of a shoe showing the work of the machine.
The column 52 of the machine has support for a treadle 4 connected by means of a rod 5 and intermediate devices with rack bars 6. These rack bars actuate a series of like d.e vices at each side of the shoe. The bars engage pinions 8 arranged to turn shafts 10, each irovided with a screw-threaded portion 12 which receives a sleeve 1% loosely mounted on the iim'ardly projecting arm of a bell crank 15. The bell crank is arranged to turn about an axis 16 lined in the head of the column and its forward end is pivotally connected to a sleeve 18 adapted to slide on a rod 90. he rod is connected at its inner end to a heel embracing band 26 arranged to extend around. the heel portion of the shoe. The band is provided at with a. shoe engaging pad which with the hand constitutes the back stop for the shoe which is to be operated upon in the machine. The band provided near its front ends with extended pads 36 for engaging the sides of the shoe at and adjacent to the front ends of the heel stiffener.
The shaft 10 has toothed engagement at its forward end with rack teeth on the sliding carrier it) which movable transversely of the machine in suitable guideways formed in the head of the column. The carrier 41:0 has tongue and groove connection with a block that is arranged for adjustment inwardly and outwardly, and pivotally supports an endwise acting presser 4st which is slotted to embrace a stud 15 which acts through the spring 46 for yieldingly actuating the presser. This presser provided at its inner end with a thin plate or blade 50 which may be formed to engage the shoe stock with a wiping action at and adjacent to the edge of the last and to enter the crease between the upper and the outwardly projecting sole-attaching flange or welt of the shoe. The presser n is arranged for pivotal movement about the stud 4.5 and is supported from below by an adjustable stop while the blade 50 may also rest upon and be guided by the upper edge of the pad 5-36 toward position to engage the shoe under the welt. The blade is supported in inclined position so that it will readily slide up the side of the shoe and find the welt crease without any attention from the operator. The carrier 1 :0 also supports on its lower inner edge a wiper GO beveled at its front end and preferably corrugated on its lower face and adapted to move inwardly over the welt and the inseam to assist the presser blades 50 in tightening the shoe stock over the edge of the last.
A spindle (35 supports the shoe against an abutment 66 depending from the machine in position to engage the heel portion of the shoe bottom. This abutment may be arranged to yield upwardly against the tension of a moderately stilt spring 68. The spindle is shown as pivoted at 70 to a rack bar 72 and adapted to swing outwardly into the dotted-line position shown in Fig. 1 to facilitate the application and removal of the shoe. The rack bar 72 extends through a member 7 1 guided in the side of the column 2 and is engaged by a toothed lever pivoted to the member 74: by which the spindle and the shoe may be manually up lifted to present the shoe in position to be operated upon after it has been swung from the dotted-line position into the full-line position shown in, Fig. 1. The lever 75 has a, pawl for engaging a ratchet 7G to hold the lever in adjusted position. The member T41: has connection through the link 78 with the upwardly projecting arm of a bell crank lever 80, said arm and link forming a toggle.
The bell. crank 80 is pivoted to a bracket extending from the column of the machine and at its rear end is connected by a rod 82 with a crank 84 on a shaft 85, which is mounted in suitable bearings in the head of the column and is driven through gears 86 and 88 from the driving shaft 90, on which runs loosely a pulley 92. A clutch bolt 94 extends from a collar 95 fast on the driving shaft through the gear 88 and into the hub of the otherwise loose pulley 92. The clutch bolt has a pin 96 extending through a slot in the collar 95 into position to be engaged by the inclined face of a clutch controlling clevice 98. This controlling device is pivotally mounted on a stud 99, which also supports a lever 100 that carries a tilting bar 102, having on its inner end a shoulder 104 adapted to be held by the spring 103 in engagement with the device 98 and withdraw that device from the stud 96 when the lever 100 is rocked. The collar 95 has a stud 106 arranged to engage the inner end of the tilting bar 102 after the machine is started and swing the shoulder 104 downwardly away from the controlling device 98 to permit the spring 108 to return said device into position to engage the stud 96 when the driving shaft has completed one revolution. Any other usual form of one revolution clutch mechanism may be substituted for that described.
The lever 100 above referred to as the actuator for the clutch controlling device is connected by a rod 110 to a block 112 arranged for sliding movement in a frame 114, which constitutes one member of the connection between the treadle rod 5 and the rack bars 6 earlier referred to. This frame 114 has the slide bar 115 arranged for endwise adjustment by a screw and slot at 116 and formed at its upper end for engagement with the tails of pawls 118 carried by the block 112. This plate 115 holds the pawls out of engagement with a series of ratchet teeth formed on the frame 114 until the frame has been moved downwardly with relation to the block 112 and to said pawls far enough to release the latter. A spring 120 thereupon throws the pawls into engagement with the ratchet teeth and the frame and the pawls then form a connection between the treadle rod and the clutch rod 110 by which the latter and the clutch are actuated from the treadle. A spring 122 is arranged to sustain the weight of the block 112 and raise it after it has been depressed by the engagement of the pawls with the frame 114. The upper end of the frame 114 is formed with laterally projecting arms yieldingly connected with the rack bars 6 by the rods 125 and springs 126, one only of which is shown in Fig. 2.
The actuation of the driving shaft when the clutch is operated turns the shaft 85 and the crank 84 thereon to communicate motion to the last supporting spindle for raising the shoe against the wipers 60, whereby the shoe stock engaged by said pressers is compressed and leveled down upon the shoe bottom to form a seat for the outersole. The spring 68 permits the abutment or bottom rest 66 to yield during the compressing operation so that the entire compressing force is received by the wipers 60. The shaft 85 carries also a cam 140 for actuating a rod 142 that extends to a tack separating and delivering mechanism supported on the head of-the column. This mechanism may be of any suitable construction adapted to supply a plurality of tacks to the conductors 144 at each operation of the machine. The tack supplying mechanism is timed to deliver the tacks from the conductors into the driver passages when the carrier 40 occupies its retracted position away from the shoe. The driver passages terminate in suitable tack holders mounted in a block 152 detachably secured to the carrier. The drivers 150 are carried by a bar 155 which is guided in thecarrier 40 and provided on its upper end with a roll for making contact with the driving head 156. This driving head is connected by a link 158 with a crank 160 on the shaft 90'. This crank is set to actuate the drivers for inserting tacks into shoe stock while the stock is under compression between the last bottom and the wipers 60. The wipers 60 are recessed to permit tacks to be driven through them and may be connected to the carriers 40 as indicated at 63 in Fig. 2 to permit them to rock laterally for adjusting themselves to the surface of the work.
The pressers 44 are each connected with a bell crank 176 that is pivotally connected at 174 with the block40 and has a lower arm that engages an extension 177 on the carrier 44. The upper arm of the bell crank is connected to a rod 17 2 which extends up Wardly and is guided in the nailing head 156. The collar 178" is adjustable on the rod and is positioned to be engaged by the nailing head for slightly retracting the presser blades 50 fro-m the welt crease as the shoe is raised to compress the stock against the wipers, so that the blades will not prevent the crease being closed tightly by the compressing operation. The parts are relatively timed so that the blades hold the shoe stock in its tightened condition until sufficient pressure has been applied so that it is held by the wipers and it is necessary to withdraw the blades only slightly to avoid obstruction to the compression of the stock of the inseam.
The carrier 40 is grooved in its rear side as shown in Figs. 3 and 4 to receive a knife block 1 adjustably connectedby a pin and slot at 3 to a lever 7 which is fulcrumed on the carrier at 9 and is connected by a link 11 to a block that is attached to and moves with the driver bar 155 to reciprocate automatically the knife block in time relation with the driver. The knife 17 is formed as shown in Fi 4tand to present a horizontal stitch cutting blade and an inclined welt butting or beveling blade. The knife rests at its inner end upon the upper face of the presser plate 50, which engages the stitches in the inseam crease, to he supported and guided by that plate which constitutes a guard to prevent the knife from injuring the upper. The vertical position of the plate varies, as has been exl'ilained, and the knife is therefore arranged to spring up with the blade, being seemed to its block by the single screw 19 and the stud 21 and having a relatively narrow shank. lVhile the stitch cutting blade and the welt butting blade might be formed separately, their formation in a single knife both insures a continuous cutting edge for completely severing the surplus portion of the weltfrom the shoe and also gives to the knife sufficient transverse rigidity to insure the maintenance of its form. The blades are each formed, as shown best in the plan view, to present a slanting edge. the stitch cutting blade severing the stitches progressivet; and the welt beveling blade engaging first the upper portion of the welt and by its form tending to hold the welt down as the cutting progresses. To assist in holding the welt the wiper (it) has a companion block (31 that is yieldingly connected to the wiper 0 to subject the surplus end portion of the welt to a yielding holding pressure during the welt butting operation and thereby insure a clean cut and an even bevel. The welt which is damp or in temper at the time it is sewed to the shoe is yet in condition to cut easily at the time the shoe reaches the welt lmtting and, of course, it cuts easier by passing the knife cdgewise through the we t than if the knife cut down upon the welt as has been heretofore propos The knife not only bevels the welt and severs any stitches that may extend back of the welt; butting point but also preferably advances inwardly beyond the inseam to plane olf any upstanding portion of the upper or inner-sole lips that may project into its path whereby an even seat for the heel portion of the outersole is produced. For removing the surplus stock after it is severed the clearer is yieldingly carried by the wiper (30 to slide inwardly over the welt and then drop down behind it into position to pull out the surplus stock that has been cut otli as the wipers are retracted after the compressing, cutting and tacking operations. The clearer 23, while occupying its innermost position, serves the additional purpose of means to ei'igagc the welt or the inner side of the betwecn-substance adjacent to the welt, and. resist inward displacement of the welt by the cutter 17. The clamp 61 may be fastened directly to the clearer 23.
In the use of the machine a shoe, which may have been previously lasted and welted, may be applied to the spindle 65 as indicated in dotted lines in Fig. 1. The shoe is swung into the full-line position, during which movement it is thrust into the heel embracing band and stopped against the pad 35. The pad. together with the band will have been positioned by suitable adjusting devices so that the shoe will be stopped with the end portions of the welt and the other portions of the shoe in suitable relation to the knives 17 and the other operating devices. hen the shoe has been properly positioned the treadle 1 is depressed and through the rack bars (3 rotates the shafts 10. These shafts through the devices connected with them first move the pads 36 against the sides of the shoe, firmly clamping the shoe stock against the sides of the last. The presser blades 50 are also actuated inwardly to engage the shoe stock in the welt crease, exerting their inward pressure against the upper and the welt and finally against the inseam to force the welt and the inseam inwardly toward the middle of the last, tightening the upper and stiffener over the edge of the lastand holding it: under tension. The two wipers (30 move inwardly with the presser blades and by the engagement of their roughened surface with the upper face of the welt assist in tightening the shoe stock over the edge of the last and holding it, particularly the welt, in proper relation to the last bottom and against displacement during the cutting and other operations, the clamps 61 resting yieldingly on the welt with just sufficient pressure to hold it against displacement by the cutting knives.
If desired, the treadle may be moved up and down to press the stock into place and position the welt accurately by repeated movements of the described devices engaging the shoe. To enable such repeated movement of the treadle to be effected without liability of actuating the clutch a sliding stop 199 may be arranged, as shown in Figs. 1 and 2, to stand normally under the carrier 114 and prevent the treadle being depressed far enough to disturb the clutch. This stop device is arranged to be readily withdrawn against the tension of its spring 198 when the stock has been forced into position to be compressed and secured. A final or further depression of the treadle serves to move downwardly the carrier 11st and when the plate 115 slides off the tails of the pawls 118 the pawls engage the ratchet teeth 011 the carrier and through the described connections cause the clutch controlling device 98 to be withdrawn from the path of the pin 96, whereupon the clutch bolt is automatically thrown into engagement with the continuously rotating pulley 92 and the shafts 90 and 85 are caused to make one complete revolution and are then arrested by the clutch controlling device. In this rotation of the shafts the crank 84; effects the elevation of the heel spindle, thus forcing the shoe upwardly against the wipers 60 and compressing the stock covered by the wipers against the bottom face of the last. While the stock is held' under compression the crank 160 effects the depression of the driver bars and thereby the actuation of the knives 17 for butting the welt, cutting the inseam stitches back of the bottom point and planing off any projecting portions of the stock so that an even heel seat will be made. The driving of the tacks will be effected while the cutters are operating, the tacks being inserted by pressure rather than by impact. It will be noted that the wipers 60 act at and adjacent to the location of the heel breast. By compressing this stock a firm seat is made for the heel breast. The yielding connections 125, 126 between the treadle and the rack bars 6 permit the final depression of the treadle for operating the clutch. As the parts are retracted to their starting positions the clearers 23 dislodge from the shoe the surplus stock that has been cut off by the knives. The blades 50 extend between the cutting edges of the knives and the shoe upper at all times except when the knives are advanced to do their work and at that time the blades form guards and guides that prevent injury of the upper by the knives on the side of the shoe and in the crease as will be seen from the drawings.
