  • Surroumling the sleeve 90 is a sleeve 96 having an external boss 97 entered by an adjusting screw 98 which has a bearing in a block 99 pivoted atlOO in a wing 101 of the arm 71). As the screw extends nearly parallel with the slot 93, it serves to adjust the feeding finger pivot along such slot, while the pivotal mounting of the block 99 allows the screw to swing as much as may be necessary to permit the pivot to follow the curvature of slot 93.
  • both the nut 97 and the finger 78 are able to swing on the pivot sleeve 90. Adjust is freely permitted.
  • the finger is held up to the work by a spring 102 coiled about the sleeve )6 and secured thereto, one end being hooked under the finger.
  • I prefer to make the point. 78 of the finger separable from the body ot the finger in order that it may be removed for sharpening and replac ed without. the bother of removing the entire finger and of disasseml'iling all the parts associated with the finger in order to do so. Accordingly the point is a separate piece which is held. rcmovably upon the body of the finger by a steady pin 103 and a screw 104.

  • the pivot ot' the finger is adjusted in slot 93, no change of this position of the finger point occurs. however great the adjustment may be. but in the other limit of the feeding. which is the position shown in Fig. 7, a great change may be made in the position of the linger point.
  • the entire adjustment of the. finger occurs at. one end of its i'novement, that is, the c muncncenu-nt ot the movement.
  • ⁇ djaccnt to the feed linger and preferably arranged on opposite. sides thereof are two or more fingers 111 mounted upon pivot pins 112 supported from the table beneath the latter, which fingers are actuated by springs 113 so as to press the sheet or strip of stock against the plate 73 at points very close to the die.
  • '1hese fingers become useful when the end of the stock approaches the die, as they hold the last bit of stock in place. against the. block and prevent. the ends of the strips from dropping and being wasted.
  • the block is movable so that every part of its surface may be brought over the die to prevent uneven cutting away.
  • lvlovcmcnt for this purpose is produced in part automatically and in part by manual adjustment.
  • the automatic movement is a rotary one and may be called for convenience an indexing' movement.
  • l't is produced by a disk cam 11!. the shape of which is shown in Fig. 2, on the shaft 17 which acts upon a roll 115 carried by a lever 111i pivoted on a stud 1.17 and having an arm .118 connected by a link 1.19 with a pawl carrier .120 arranged to travel upon the periphery of the plate 1 previously mei-itioned, and embracing a circular line.
  • the pawl carrier has two pawls and 11231 separated by a distance which is a multiple of half the spacing of the teeth 1521. and which is adapted to enact with these teeth.
  • the amount o't movel'nent given to the pa 1 carrier is governed by a stop screw 12 1 carried by the lever 11S and adjustable thereon. This stop screw limits the amount by which the roll 115 follows the cam 11-1- to any desired extent and there by enables the indexing movement to be 'arrled from a minimum of half the-tooth spacing to a maximum of several times this amount. This indexing movement presents a fresh surface of the block to the die at each 'cut until one rotation has been completed.
  • the other adjustment of the block is occasioned by swinging the arm 7 about the stud 5 to cause the die to act against another circular zone of the blocks surface.
  • the hub 6 of the arm 7 is split and is provided with take-up screws 125 to draw the parts together, whereby the arm may be sew cured by clamping after each adjustment.
  • the pawl carrier 120 travels in a curved path in a horizontal plane while arm 118 moves in a vertical plane.
  • the link or connecting rod is engaged with the arm 118 by a horizontal pivot 126, ayoke 126, and a vertical pivot 126", while the connection between the link and 'pawl carrier is made through a yoke 127 having a vertical stud 128 journaled in the end of the link 119 and having lugs which straddle the pawl carrier and are pivoted thereto by horizontal studs 129.
  • the table and the feeding means are all. adjustable in unison vertically to a limited extent and are all carried by a slide 130, the table being secured upon a plate 131 on the top ,of
  • a bearing sleeve 81 which forms a part of the slide.
  • the latter is removably secured to the machine frame by bolts 132 passing into the body of the frame through slots 133 in the slide and having clamping heads overlying the edgesof .the slots.
  • the slide is guided by one edge of an angle piece 134 i which is secured to the body part of the machine frame and forms a portion thereof.
  • a hand lever 135 pivoted at 136 and connected with the slide by a link 137. It is for the purpose of permitting this adjustment that the telescopic shaft drive and flexible coupling are provided for the shaft 181.
  • the bearin .138 which supports the telescopic shaft as a swivel mounting at 139 upon the machine.
  • The. feed may be made inoperative by a latch 140 hung on a pivot 141 at the side of the'frame and adapted toengage a tooth 142 on a collar 143 which issecured to thesleeve 86 of the telescopic driving shaft.
  • the shaft and the collar 143 may be turned far the direction of feeding to cause the latch to engage the tooth 141.
  • These parts then hold the'finger somewhat beyond the most advanced position given it hy the cam' 82, whence the'cam; may rotate 1dly the invention is limited only to the principles of construction and operation of which the construction shown herein is one exemplificatiop. All changes and modifications coming within the language of. the annexed claims are included under my invention. It is within the scope of the invention to make the dies double and to have the strips or sheets of stock sufliciently wide to overlie the double die, whereby two complete lifts or other articles may be cut at one operation.
  • the parts of the double die 1 are the reverse ofone another, so that a pair of similar but opposite articles maybe out at one operation.
  • a feature of great importance in the present invention is that they block is above the die and is relatively stationary, while the die in cutting moves back and forth across. the line in which the stockis fed.

or die having a cutting edge of the desired outline.
The pan-titular machine illustrated in the accompanying tlrawings and particularly described in the following specification, which is one embodiment in practical form of my invention, is designed to cut lifts or pieces, to be used in the manufacture of boot and shoe heels, from sheets or strips of leather, leather board or like material, but the principles of the invention areequally applicable to cutting out other articles from the same or similar stock.
The principles in which the invention consists are discussed and explained in connection with the following detailed descrip- 'tion of the particular form of means of carrying the invention into effect which I have shown for illustration herein.
In the drawings, Figure 1 represents the machine referred to, in' front elevation, a part of thesame being shown in section. Fig. 2 is a side elevation of the machine. Fig. 3 is a sectional elevation on line 33 of Fig. 2, she-wing a detail. Fig. 1 is a plan view of the guiding and supporting means for the stock. Fig. is a cross section on line 5--.5 of Fig. 1. Fig. 6 is an elevation onan enlarged scale of the stockfceding means: the supporting table and cutting diobeing shown in section. Fig. 7

Fig. 11 is a sectional view on line 1111 of Fig. 1. i Fi 12 is a plan viewof the die and its holder.
Like reference characters indicate the same parts in all the views.
1 indicates a supporting frame on the upper part of which is a post or head 2 hav- "of the post 9.
ing vertically alincd separated hearings or sockets 3, -l' in which is fixed a pin 5 surrounded by a split sleeve (3 which is one end of a horizontally extending arm 7, the other end of which has a bearing 8 containing rotatably a shaft or post 9 to which a cutting block 10 is secured. This block constitutes the bed or abutment which sustains thestock or material against the thrust of the die when the heel lifts or other articles are being out. .It is prefl-n'ahly made of wood, but maybe of any other material having the essential qualities of firmly supporting the material and of not injuring the cutting edge of the die. It is cylindrical in form and is secured coaxially with the post.
9, the securing means being conveniently clamp-screws 11 which pass through lugs 12 embracing the block at one end' and carried by a plate 13 which is fastened by bolts 14 to a flange 15 in the lower end Rising from the arm 8 and overlying the post 9 is a goose-neck 16' having an aperture coaxial with the post 9 through which extends a screw 17 which has a threaded engagement with the post as shown in Fig. 1. A hand wheel 18 issecured to the end of the screw and rests on the upper side of the goose-neck, being ro tatable thereon as the screw is fully rotatable within the goose-neck. The post 9 is also freely rotatable within the bearing 8, sothat it may be turned more or less from time to time as will be hereinafter described. A block 19 which fits the threads of the. screw 17 is set into a passage in the side of post 9 and'is pressed against the screw by a spring 20 which abuts a ainst a screw 21 threaded into the outer end of the passage. The function of this block is to act as a friction device preventing relative rotation of the postand screw when the. block is .indexed as hereinafter described, but permitting the screw to be turned relatively to the post for adjusting the height of the block.
The, cutting element is av die 22 beneath the block, of which the cutting edge extends 25 a to fall'l'nto a receptacle. The carriage itsel't flat top 27 of a carriage 28 which recipro-- cates vertically and has guiding flanges 29 contained in guide ways 30, formed on thefront part of the machine frame and being of any usual or desired form. The top part 27 of the carriage has ribs 31 at opposite edges between which the plate 23 fits, and
on which are retaining strips 32 overlying the edges of the plate. Thus the dieholding plate is removable from the carriage, and plates equipped with dies of different sizes and forms may be readily substituted for one another. A locking pin 33 passes through one of the ribs 31 into a hole in the plate 23 and is retained therein by a spring 34 which is a strip of spring steel fastened at one end to the rib 31 and engaged near its free end with the pin. This v pin insures retention of the die-holding plate upon the carriage and placing of any of such plate in the proper position; As shown in Fig. 11, both the die supporting plate and the top plate of the carriage are apertured in line with the hollow interior of the die to allow the pieces cut by the die is so made as to allow the pieces to fall away without obstruction, its central part 35 between the cut flanges 29 being inclined backward. Stiifening webs 36 extending forwardly are provided on each side of the inclined central "part.
The operating means-by which the die carriage is reciprocated consist of" a lever 37 pivoted upon a stud 38 between lugs 39 of the frame, having a forked end 40 emv51 and fed beneath the block 10 close to the 1 under side thereof. On the table is a guide 52 (see Fig. 4) which engages one edge of thestock and positions the same relatively to the die. Preferably guide 52 is adjust-- able so'that the edge of the-stock, may be 'brought more orless close to the periphery of the die,-and' for this purpose it is mounted pivotally upon a stud 53 rising from the table, and is adjusted by; means of a screw 54;held rota-tably in the lug 55 on the table and threaded into ablock 56, which is pivotally mounted upon theguide. v A head 57 is secured on the screw to enable thesame to be easilyturned between the thumb and finger-of the operator. Y
The particular 1nacl1ine. illustrated is designed to act'upon strips-of stock having :1
therefrom, although the invention, is not limited in allits aspects to this feature. Therefore I provide a com'plemental guiding 'means adapted to engage the opposite edge of the strip from that engaged by guide 52, and to hold the strip incontact with said guide, such means consisting of arms 58 and 59 pi'voted at 60 and 61, respectively, upon a plate 62 supported on the table. The arms have alined projecting portions adapted to engage the edge of the strip, which are pressed toward the latter by springs 63 and 64 arranged asshown in Fig. 401* in equiv alent manner. 'Stops 65 and 66 are provided to limit the amount by which these springs may move the guiding arms. The plate 62 is adjustable on the table and has slots 67 extending in the direction of adjustment through which clamping screws (38 extend such screws being threaded into the table and having heads adapted to bind the plate to the table in anyvwcll known manner. An adjusting scre 69 having a head 70 is journaled in a bearing 71 in the table and threaded through a part 72 of the plate. By .this means the guide arms 58 and 59 may be adjusted to accommodate strips of various widths, and the yielding mode of mounting the arms adapts the latter to accommodate themselvesto irregularities in the width of the strips. On the guide 52'is mounted a plate 73 of which one end extends under the block and has a lateral pro- ,jection 74 extending across more than the entire width of the strip. Theguide arms 58 and 59 carry, respectively, plates 75 and 7 6 which overlie the edge of the strip en-' gaged with ,saidarms. These strips cause the advancing end of the strip to pass un der the block without interfering therewith and also prevent any part of the strip from buckling and escaping from guiding elements.
-'The feeding meansconsists of a pointed etween the The ends of the plates.
under whichthe strip first passes are preferfinger 78 carried by anarm-79-on a shaft 80 which is held in a bearing 81 and is moved oscillatively by a cam.82 having an axially 'ofiset cam face 83, as shown in Fig. 1.- The cam element acts on a roll carried by an arm 84 (.see'Fig. 2) afiixed to a telescopic shaft consisting of a key-coupled rod 85 and sleeve 86, which latter is connected with the shaft v 80 bya universal joint 87 Themotion pro- I arm.
duced thereby swings the arm 79 and finger 78 from right to left as viewed in Figs. 1, t5,
and 7 causing the point of me finger to enterfixed part of the machine.
Adjustn'ient of the finger to secure di1l'erent extents of feeding movement, but without altering the position of the finger at the end of feeding movement, however great the extent of such movement. may be, accomplished by mounting the finger T8 movably upon the arm 79. This finger is journaled upon a sleeve 90, shown in Fig. 8, having a flange or head 91-aml surrounding 'a pin 92 which passes through a slot 93 in the arm 79 and has a head 94- on the oppo site side of the arm from flange 91. A nut 95 is screwed on the pin 92 and serves to force the flange 9t and head 91 toward one another or to release them, sothat the pivot may be placed and secured at any point within the limits of slot 93. Surroumling the sleeve 90 is a sleeve 96 having an external boss 97 entered by an adjusting screw 98 which has a bearing in a block 99 pivoted atlOO in a wing 101 of the arm 71). As the screw extends nearly parallel with the slot 93, it serves to adjust the feeding finger pivot along such slot, while the pivotal mounting of the block 99 allows the screw to swing as much as may be necessary to permit the pivot to follow the curvature of slot 93. As both the nut 97 and the finger 78 are able to swing on the pivot sleeve 90. adjustment is freely permitted. The finger is held up to the work by a spring 102 coiled about the sleeve )6 and secured thereto, one end being hooked under the finger. I prefer to make the point. 78 of the finger separable from the body ot the finger in order that it may be removed for sharpening and replac ed without. the bother of removing the entire finger and of disasseml'iling all the parts associated with the finger in order to do so. Accordingly the point is a separate piece which is held. rcmovably upon the body of the finger by a steady pin 103 and a screw 104. l have shown associated with the finger a means for preventing the point from pcnctrating too far into the stockfsnch means con'iprising an arm 105 adjustably mounted on'the finger by means of a screw 10G passing into the finger through a slot 107 in the Such arm carries on its outer end a roll 108 designed to run on the under side ot the table beside a slot 109 in the latter thrmigh which the linger point projects to engage the work. This arm is not an important part of the invention and may be omitted without detriment. In one form of the invention which 1 have put into practice the arm is omitted and the finger allowed to enter the stock as r'ar as it will. When no stock is present the finger makes contact with a hardened steel strip 110011 the under side of plate 73.
In order that. the finger may be so adjusted as to vary the extent of feeding atwhich feeding ceases, 1' make the slot 93 on a curve of which the radius is equal to the distance between the point of the finger and the pivot. thereof", and the position of the groove in the arm 79 is such that when the arm and finger are at the end of the feeding movement the center of curvature of the slot. is at the point of the finger. Thus, when the pivot ot' the finger is adjusted in slot 93, no change of this position of the finger point occurs. however great the adjustment may be. but in the other limit of the feeding. which is the position shown in Fig. 7, a great change may be made in the position of the linger point. Thus it may be said that the entire adjustment of the. finger occurs at. one end of its i'novement, that is, the c muncncenu-nt ot the movement.
\djaccnt to the feed linger and preferably arranged on opposite. sides thereof are two or more fingers 111 mounted upon pivot pins 112 supported from the table beneath the latter, which fingers are actuated by springs 113 so as to press the sheet or strip of stock against the plate 73 at points very close to the die. '1hese fingers become useful when the end of the stock approaches the die, as they hold the last bit of stock in place. against the. block and prevent. the ends of the strips from dropping and being wasted.
The block is movable so that every part of its surface may be brought over the die to prevent uneven cutting away. lvlovcmcnt for this purpose is produced in part automatically and in part by manual adjustment. The automatic movement is a rotary one and may be called for convenience an indexing' movement. l't is produced by a disk cam 11!. the shape of which is shown in Fig. 2, on the shaft 17 which acts upon a roll 115 carried by a lever 111i pivoted on a stud 1.17 and having an arm .118 connected by a link 1.19 with a pawl carrier .120 arranged to travel upon the periphery of the plate 1 previously mei-itioned, and embracing a circular line. oi" ratchet teeth 12.1 on said plate. The pawl carrier has two pawls and 11231 separated by a distance which is a multiple of half the spacing of the teeth 1521. and which is adapted to enact with these teeth. The amount o't movel'nent given to the pa 1 carrier is governed by a stop screw 12 1 carried by the lever 11S and adjustable thereon. This stop screw limits the amount by which the roll 115 follows the cam 11-1- to any desired extent and there by enables the indexing movement to be 'arrled from a minimum of half the-tooth spacing to a maximum of several times this amount. This indexing movement presents a fresh surface of the block to the die at each 'cut until one rotation has been completed. The other adjustment of the block is occasioned by swinging the arm 7 about the stud 5 to cause the die to act against another circular zone of the blocks surface. The hub 6 of the arm 7 is split and is provided with take-up screws 125 to draw the parts together, whereby the arm may be sew cured by clamping after each adjustment.
It will be noted thatthe pawl carrier 120 travels in a curved path in a horizontal plane while arm 118 moves in a vertical plane. To permit these movements, the link or connecting rod is engaged with the arm 118 by a horizontal pivot 126, ayoke 126, and a vertical pivot 126", while the connection between the link and 'pawl carrier is made through a yoke 127 having a vertical stud 128 journaled in the end of the link 119 and having lugs which straddle the pawl carrier and are pivoted thereto by horizontal studs 129.
The table and the feeding means are all. adjustable in unison vertically to a limited extent and are all carried by a slide 130, the table being secured upon a plate 131 on the top ,of
the slide, and the shaft 80 upon which the. feeding finger is supported being contained in a bearing sleeve 81 which forms a part of the slide. The latter is removably secured to the machine frame by bolts 132 passing into the body of the frame through slots 133 in the slide and having clamping heads overlying the edgesof .the slots. The slide is guided by one edge of an angle piece 134 i which is secured to the body part of the machine frame and forms a portion thereof. When the clamping bolts 132 are -released the slide and all parts carried thereby may be raised by means of a hand lever 135 pivoted at 136 and connected with the slide by a link 137. It is for the purpose of permitting this adjustment that the telescopic shaft drive and flexible coupling are provided for the shaft 181. The bearin .138 which supports the telescopic shaft as a swivel mounting at 139 upon the machine.

By lifting a handle 144' on the arm 79 the shaft and the collar 143 may be turned far the direction of feeding to cause the latch to engage the tooth 141. These parts then hold the'finger somewhat beyond the most advanced position given it hy the cam' 82, whence the'cam; may rotate 1dly the invention is limited only to the principles of construction and operation of which the construction shown herein is one exemplificatiop. All changes and modifications coming within the language of. the annexed claims are included under my invention. It is within the scope of the invention to make the dies double and to have the strips or sheets of stock sufliciently wide to overlie the double die, whereby two complete lifts or other articles may be cut at one operation. The parts of the double die 1 are the reverse ofone another, so that a pair of similar but opposite articles maybe out at one operation.
A feature of great importance in the present invention is that they block is above the die and is relatively stationary, while the die in cutting moves back and forth across. the line in which the stockis fed. As a result of this arrangement it frees itself of the stock, and the scraps do not rest upon or adhere to the block in such a way as to interfere with subsequent operations. Thescrap which passes beyond. the die falls into -an inclined guide way 150 bywhich it is led away to one side. Some of the scrap falls beside the die, and in order to prevent it. from dropping into the receptacle placed beneath the carriage toreceive complete ,articles,I provide deflector plates 151 and 152,v the former of these is fastened to the front edge of the die-holding plate 23, and
rises on an upward and rearward slant, having a hole to receive the die. The latter is secured under theforward edge of the carriage top plate and ex' ynds forwardly therefrom on an incline. These deflectors are shown only in Fig. 11, being omitted from Figs. 1'and-2 for the sake of clearness. The
edged cut-ting die and cooperating cutting members may be considered as typical of any two cooperating or complemental cut-.
ting members, and therefore I do not limit my invention or the scopeofall of my claims to the particular type of die'andcutting block her e shown.- Anycomplemental cutting members capable of forming articles in the nature of heel liftsand the like from sheets of leather, leather board,.or equivalent material are within the intended scope of the broader claims hereinafter following.
