To all who??? it 22mg, concern:

Be it known that 1, Louis A. Cnscrmm', a citizen of the United States, residing at Beverly, in the county of Essex and State of lvlassachusetts, have invented certain Improvements in Machines for Operating on Shoe Parts, 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 operating on blanks foriuse in the manufacture of boots and shoes, particularly to machines for treating heels before they are attached to shoes. Although the invention, in its broader aspects, is applicable to the treatment of shoe blanks in general, such, for example, as blanks which. are used for parts of shoe bottoms, the invention herein shown by way of exemplification as adapted for effecting operations similar to those performed by the machine disclosed in my prior co-pending application Serial No. 152,-

391, filed March 3, 1917, in which is described and claimed an automatic machlne organized to breast a heel by first removing a thick chip from the heel breast and then again treating the heel to remove a thin chip or to make a finishing out. By reason of the fact that these cuts are both made upon the heel by successive operations of a single knife more time is necessarily consumed in the heel breasting than is the case where the heel is treated by a single cut.

It is an object of this invention to provide an improved automatic machine for breasting heels which will impart a roughing cut and a finishing cut to each heel, retaining in. this and other respects important advantages characteristic of the machine shown in the said application, but which will effect these successive operations upon a heel as rapidly as the heel bros-sting operation can be effected by machines of the type which make a single out only.

A feature of the invention consists in a work support and a plurality of cutting cs constructed ant, arranged for relative reciproea oryinovement in the same direction to cause the edges to act successively to remove material from a face of the work. Thus one cutting edge continues the action of the other and the first action may be a roughing cut and the second a finishing cut. As'shown herein a heel is operated upon and the cutting edges act to remove material successively from the heel breast irst by a roughing and then by a finishing cut. Obviously other shoe blanks or shoe bottom parts may be similarly treated.

Another feature of the invention consists in a support for shoe bottom blanks arranged for movement from station to station and reciprocating stock removing cutters operating to remove stock from the blank at each of the successive stations, the organization being such that the blank is presented'to the second cutter in position to have further material removed from it. Preferably and as shown the stock removing cutters are relatively displaced to cause successive portions of stock to be removed from the blank while the position of the blank relatively to its support and the planes of reciprocation of the cutters remain un changed.

In the illustrated construction, the two cutting edges are shown as knives operated by a single operating means and therefore a roughing cut is imparted to one heel by one knife while another heel is being given a finishing cut by another knife, the machine having a heel carrier co-operating with these knives and between which and the knives there is relative movement to effect successive operations of the knives upon the same portion of the heel. As shown herein, the carrier moves to bring a heel first into the field of operation of one knife and then moves to bring the same heel into the field of operation of another knife.

In a machine such as that of my prior application above mentioned, in which one knife makes two cuts, the single edge may become too dull to give a satisfactory finishing out while it may still be capable of co tinuing to make satisfactory roughing cuts for some considerable time. hen, however, as illustrated, a roughing cut and a finishing out are performed by two distinct knives, the roughing knife may remain serviceable for its purpose after it would possibly have become too dull for finishing, and the finishing knife, being reserved for a com iarativel Y li ht out ma remain ser viceable for a longer time than if it were used also for the heavy roughing out.

In another broad aspect, features of the invention are to be recognized in an organization including a series of tools such as cutting tools for performing distinct operations upon heel blanks or the like, with means for taking the blanks automatically from a source of supply such as a magazine and presenting them sequentially to the tools for their operation on the blanks. Preferably the blanks are successively presented by intermittent movement at a series of operating stations at each of which a tool is located and the tools operate simultaneously on separate heels and successively upon the same heel. In the illustrated embodiment of the invention the machine is provided with a plurality of heel carriers co-operating with a plurality of knives, the knives and carriers being constructed and arranged for relative movement to effect operation of one knife on a heel on one carrier and another knife on a heel on another carrier. Preferably, and as shown, two knives are provided which operate simultaneously upon heels on separate carriers, one knife removing a thick chip from one heel while the other knife removes a thin chip from the other heel, the carriers being then advanced so that the heel from which the thick chip was removed will be in position to be treated by the other knife and a thin chip removed, another heel on another carrier being presented for operation of the knife which removes a thick chip. Four such carriers are shown herein arranged in an endless series, although other numbers and arrangements of carriers may be provided without departing from the invention. In the construction shown, a heel is fed to one carrier while a heel on the second car rier is receiving a roughing cut, a heel on the third carrier is receiving a finishing cut, and a heel on the fourth carrier is being removed from the machine.

Still further features of the invention are to be recognized in an organization including a plurality of blank carriers preferably arranged for intermittent movement in a horizontal plane, a plurality of operating means located at various positions of rest of the carriers for operating upon the blanks, a magazine for blanks, and mechanism for transferring a blank from the magazine and locating the blank in predetermined position on each of the carriers as as they are presented in turn. Preferably and as shown the transferring mechanism acts to orient the blank, that is, to predeterinine its rotational position about a vertical axis passing through the blank, and also acts positively to predetermine its longitudinal position on the carrier.

Further features of the invention consist in novel heel supplying mechanism co-operating with the heel carrying means and comprising a heel magazine, and heel feeding means, relatively constructed and arranged so that the magazine overhangs the carrying means and the lowermost heel in the magazine is positively pushed by the feeding means on to the carrier but only partially from beneath the stack of heels in the magazine, and the carrier then carries the heel to the breasting means. The heel being fed is, therefore, frictionally engaged by the heels above it during its movement to the carrier. The heel is consequently constantly under control and no opportunity is afforded for the heel to become misplaced relatively to the feeding means or the carrier. Preferably the heel is clamped to its carrier before the carrier moves the heel to the breasting means.

It is desirable, though not essential, that the heels in the stack be held from descent while the lowermost heel is being fed into the machine, and during the retraction of the feeding members, and a further feature of the invention consists in means having this function. In the construction shown herein the heel next to the lowermost one is forced against the far side of the magazine, thus enabling the heel next to the one at the bottom of the stack to sustain the weight of those above it while the mechanism referred to above feeds the bottom or lowermost heel to one of the carriers, clamps the heel on the carrier, moves the carrier and clamped heel from under the overhanging portion of the stack and allows the stack of heels to drop to bring the next heel in front of the feeding members. Preferably means is provided for positively sustaining one end of the heel next to the lowermost one.

A further feature of the invention consists in improved means for ejecting a heel from the machine after it has been operated upon and comprises means by which power to effect ejection of the heel is stored up while the heel is being operated upon by the machine and is released to effect ejection of the heel after the work upon it is completed. As shown herein, a spring is arranged to be engaged and put under tension by a heel when it is inserted in the machine, the spring being held under tension until the heel has been subjected to the successive cutting operations after which it is released and expels the heel from its carrier. Furthermore, contact of the heel with the spring, while it is being fed into the machine, acts to steady the heel and prevents lateral displacement of the heel on its carrier.

A further feature of the invention consists in an organization comprising means for holding a blank or heel in one of a series of movable carriers to which the heel is fed while the carrier is at rest, with means oper ated by movement or the carrier for releasing the holding means. As shown the hold ing means is a clamp which acts independently of movement of the carrier to hold the blank or heel in the position in which it is presented to the carrier and during the successive operations thereon and is afterward released, tor example, by movement of the carrier to permit removal of the heel, for example by the ejecting means above mentioned.

Considering the above noted clamping and ejecting mechanism more broadly, entures of the invention are to be recogniv in tne combination of a blank support, means for presenting a blank on tie i, rt, means for moving the support through a plurz l of positions at which operations are performed on the supported blank, together with a clamping member ii'iovable into ongagement with the blank to hold it on the support and means situated diii'erent posi tions on the support for controlling the engagement 01 the blank with the clamping member and its release therefrom.

l Vhile the invention is herein shown and described as embodied in a machine for breasting heels, it will be clearly apparent that the invention is not limited in its application to such a machine ant that var" features of the-invention are ad bodiment in machines for otl These and other features the invention and various novel combinations will appear more fully from the following detailed do scription when read in con ection with the accompanying drawings and will be pointed out in the appended claims.

hine en VliYW 03 T 1361383118111 Referring to 1 m the drawings, the incicates the frame of nun'ieral 2 chine. In a in effect integral vertical shaft tati ng table or spider i tour heel carrying plates 10, 11 Each of these plates or i 1'3 and 1e. 5 is pivoted to the spider 8 near its outer end. at 12 its rear end has downwardly directed log 14. The lugs 14. rest on collar 16' threaded on the shaft 6. The vertical position of the collar 16 on the shaft determines adjustably the relation of the up er surfaces of the carriers 1O, 11, 13 and 15 to a horizontal plane. This adjustment of the carriers determines the angle between the breast face of the heel and its "tread lace wh .1 the breast end is cut oil by vertically moving knives to be described.

On the shaft 6 below the frame a is pinned a tour toothed ratchet plate 20 (Fig. 3) below which is rotatably mounted on the shaft 6 a lever 22 carrying at one end a pawl 24: engaging the teeth or" the ratchet and at the other end being connected by a link 26 pivoted to a block 27 journaled in the upper end of an arm 28 (Fig. 1). The arm 28 is pinned to a rock shaft 30 journaled in the frame 2 and having pinned to its opposite end another arm 32 which carries a cam roll engaging a cam path 34 in the inner face of a wheel 36 to which power is applied to drive the machine. The cam path 8 L will act through the mechanism described to rotate the plate 20 and the table 8 one-fourth of a revolution at each rotation of the wheel 36 as will be readily understood.

To maintain the table 8 exactly in the position into which it is brought by action 01 the pawl 24, an indexing pin 40 is provided which has a conical lower end adapted to engage similarly shaped holes 4:2 in the ratchet plate 20. In the position shown in Fig. 1, the pin 40 is held raised against a spring 44. by a bell crank lever pivoted at 3:6 and having one arm connected at 8 to the pin 40 and another arm positioned to be engaged by the upper end of the arm 28. As the arm 28 is moved outwardly by its cam to cause rotation of the plate 20, the arm 50 is released, allowing the pin 40 to be depressed by its spring 4% toward the plate 20 but by reason of the cam shape of the end of the arm 50 the pin 40 is not allowed to engage the plate until the plate has moved enough to bring the adjacent hole 42 out of alignment with the pin. Therefore, the pin will rest on the upper surface of the plate 20 and snap into the next indexing hole 42 when the limit of the throw of the pawl 24: for a given movement thereof is reached, holding the plate indexed during the return movement of the pawl to engage the next tooth of the ratchet 20, and being released only when the end of that movement is approached.

Guided for vertical movement in the frame 2 is a cross head 66 shaped in cross section as shown in Fig. 2 which is reciprocated by a crank 62 (Fig. 1) on a shaft 64- which carries the drive wheel 36. The crank 62 is connected to the cross head by a connecting rod 66.

The cross head 60 carries two breasting knives 67, 68, shown in section in Fig. 2, one being in position to breast a heel 0n the carrier '11 and the other in position to breast, at the same time, a heel on the can rier 13. The knives 67 68, are arranged at slightly different distances from the center of the shaft 6 so that while the knife 67 is effecting a first or roughing cut on a heel on the carrier 11 the knife 68 is effecting a second or light finishing out upon the heel on the carrier 13. In the next position of the table 8, the heel on the carrier 11 already breasted once will receive a finishing cut from the knife 68.

Mechanism is provided for feedin heels one by one from a stack of heels to t e carriers 10, 11, 13 and 15. The magazine containing the stack of heels comprises vertically arranged angle bars 70, 72 for engaging the corners of the heels at the breast ends. The bars 70, 72 are arranged for ad justment to accommodate heels of different widths by means of slots in horizontal projections 7% from the bars engaged by cap screws 76. The curved sides of the heels near their opposite ends are engaged by cylindrical bars 78, mounted on arms 82 which have split clamps 84L engaging posts 86 set in the frame 4. The clamps 84: provide for adjustment of the bars 78, 80 for different sizes of heels and also for vertical adjustment of the bars 78, 80 on the posts 86 for different heights of heels. [The magazine constitutes means for presenting a heel in position to be fed to one of the carriers. The feeding means will now be de scribed.

Beneath the bars 70, 72, and in position to engage the lowermost heel of the stack, are arranged feeding fingers 90, 92, pivoted at 94, 96 respectively to a plate 98 and interconneoted at 100 for equal and opposite movement. The heel engaging ends of the fingers 90, 92 are notched to engage the, breast corners of the lowermost heel and may be set for heels of different widths by means of a thumb head 102 on a screw 104i extending loosely through an outward eX- tension. 93 on the finger 92 and threaded into a stud 105 mounted in a lug on an outward extension 91 of the finger 90.

The plate 98 upon which. the feeding fingers 90, 92 are mounted is carried on a reciprocating slide 106 1). Relative adjustment between the slide 106 and the plate 98 for different lengths of heels is effected by a thumb head 108 on a rod 110 threaded into the slide 106 and having flange 112 engaging a recess in the plate 98. The slide 106 is reciprocated positively by a link 114 connected tothe slide and to one arm 116 of a rock shaft 118 journaled in the frame 4 and having another arin 120, the end of which is bifurcated to embrace a block 122 pivoted to the cross head 60.

which are the 90, 92, below and which the slide 106 and plate 98 travel The outer end of the plate I mil away to adi'nit the pivots fi t, of the lingers during their inward veins-lit.

Since the lowermost heel is pushed only partially from beneath the stack, its front or breast portion is held frictionally by the weight of the heels in the stack, l ll; enough of the heel projects so that a vp, to e described, may engage the top race of tne heel and hold it upon the carrier as e carrier moves from beneath the stack. in this construction the heel is un ler control at all times and no chance is .en for the heel to be knocked about by the quick action of the feeding fingers and becoming misplaced upon the carrier t to it is clamped in position. Since the feeding fingers engage both breast corners of the heel, it has tendency to rotate in the plane of t movement of translation from presented position to a predetermined position in the machine but also the position of orientation of the heel or the direction of its longitudinal median line is determined.

It is desirable, although not essential, that the stack of heels be held from descent while the fingers are pushing inwardly the lowermost heel and returning to their outer position.

Mechanism for this purpose is shown in Figs. 1 and 2. A vertical rock shaft 130 journaled in the frame t carries an i 132 having a pointed projection 1% ada ted to engage at times the heel in the stack next to the lowermost one and hold the stack oi heels from descending in the mar zine. The arm 132 is connected to the si t 130 by a split clamp 136 to permit vert'cal adjustment of the projection 134: for different heights of heels. The shaft 130 is pro vided below the slide 106 with an arm 13S carrying a roll 139 which engages a cam 1 10 on the slide. When the parts are in the position shown in the drawings, the cam 140 presses on the roll 139 and rocks the shaft 130 to hold the projection 184 out of engagement with the heel. When the slide moves inwardly the roll 189 is released and the shaft 130 is rocked by a spring 142 (Fig. 2) to cause the projection to engage the heel next to the lowermost one to hold that heel and those above it from descent while the lowermost heel is being pushed over the carrier 10. At the inner end of each of the carriers 10, 11, 18, 15 is arranged a leaf spring 150 having its upper end slotted at 151 and secured by a cap screw 152 to a frame 154 secured to the vertical shaft 6. By means of the slots 151 and the screws 152 the springs may be adjusted vertically and in and out in the direction of the length of the heel, and are set so that they will be engaged by the heels pushed against them and compressed inwardly. By engagement with the end of the heel as it is pushed upon one of the carriers the at tendant spring 150 frictionally holds that end of the heel from lateral movement until it is clamped upon the carrier.

It is necessary to hold the heels clamped against the carriers after their insertion to prevent their being thrust out by the compressed springs 150 and also to hold them firmly during the subsequent breasting operations performed upon them. For this purpose there is mounted for vertical movement over each of the carriers 10, 11, 13, 15, a plunger 160. The plungers are all similar in construction and are splined to prevent rotation of them in their mountings. The portions of the frame 154 which guide the plungers for their vertical movement are re cessed to accommodate collars 162 clamped to the plungers and between each collar 162 and an adjustable sleeve 165 threaded into the upper portion of the guiding frame 154 (Fig. 4) is a stiff spring 164, and on the lower end of each plunger 160 is a clamping plate 166 which is forced against the heel, when permitted to do so, by its spring 164. The plunger at the left of Fig. 1 is shown in clamping position holding a heel on the carrier 18. The collars 162 engage the frame 154 to prevent excess movement of the plungers when no heels are under them. When each carrier 10, 11, 13, 15 reaches the position of carrier 15 in Fig. 1, it is necessary to release the clamping plate 166 and allow the heel to be ejected by reaction of the compressed spring 150. To effect this, the collars 162 are provided with rolls 170 which ride on a stationary cam 172 mounted on a depending portion 174 of the frame 2. The rise of the cam 172 is shown in Fig. 1 as acting when the carrier 13 passes to the posit-ion of carrier 15.

The clamp 166 over the carrier 10 should be held raised as shown in Fig. 1 until the heel is inserted beneath. it and should then be allowed to descend to hold the heel before it is moved to the next position where it is breasted. Thus to operate the clamp, mechanism best shown in Figs. 4 and 5 is provided. Referring to Fig. 4, the depending portion 174 of the frame is provided with ways 180 in which a slotted slide 182 is guided. The slot of the slide embraces a fixed block 184 connected by a tension spring 186 to the lower portion of the slide 182. On the lower end of the slide 182 is an outwardly extending projection 188, the upper face of which, when in the position shown, forms a continuation of the acting face of the cam 172. The roll 17 0 of the plunger which is over the carrier in the position of the carrier 10 rests on the projection 188, the slide and projection being at that time upheld by a latch 190 which engages a projection on the upper end of the slide 182, as shown in Fig. 5. The latch 190 is pivoted to the part 174 at 192 and is held in latching position by a spring 194. On the latch 190 is an arm 196 which is engaged by one end of an unlatching lever 198 pivoted at 200 to the frame 2 and carrying at its opposite end a slotted link 202. In the slot of the link 202 is arranged a pin 204 extending between lugs 206 on the cross head 60. lVhen the cross head descends, the pin 204 engages the end of the slot in the link 202 and operates the lever 198 to release the latch 190, allowing the slide 182 and projection 188 to descend under the impulse of the plunger spring 164 which overcomes the weaker spring 186, the clamp 166 on the plunger then engaging the heel on the carrier 10 while the carrier travels to the shown position of the carrier 11 and under the first breasting knife 67.

During this movement, the r0 1 170 passes off the projection 188 and the slide 182 is returned by its spring 186 to raised position against a stop 181 where it is again locked as soon as the cross head 60 starts to ascend and before the roll 170 of the next plunger arrives over it.

The mechanism of the machine has now been sufficiently described so that its operation will readily be understood, and such a description will now be given with reference to the passage of a single heel through the machine, it being understood that a similar operation is performed upon each heel as heels are fed in turn to the carriers 10, 11 18 and 15. Supposing the magazine 70, 72, 78, 80 to be filled with heels and the machine started. The cross head 60 begins to descend and the block 122, through the connections described, operates the slide 106 to carry the fingers 90, 92 against the lowermost heel in the stack and push it inwardly over the carrier 10 and against the spring 150. Early in the same movement, the cam 14-0 allows the spring 1&2 to force the point 134 against the heel next to the lowermost one, thereby pushing it against the inner guides 78, 80 of the magazine and holding up the stack of heels above it until. the finges are again retracted, whereupon the point 13a is withdrawn and the stack of heels drops to bring the next heel in front of the fingers 90, 92. During the descent of the cross head 60, the pin. 204% hits the end of the slot in the link 2052, operating the lever 198 to unlatch the slide 182 and allow the spring 16-1 of the plunger over the carrier 10 to operate and clamp the heel upon the carrier 10. During the return of the cross head the table 8 is rotated by the means described 0ne-fourth of a revolution, and the heel clamped on the carrier 10 is brought under the knife 67 which, upon the nerd; descent of the cross head 60, removes a thick chip from the breast end of the heel as the first or roughing cut. The cross head again ascends and the heel is brought to the third posit-ion. under the second breasting knife 68, Where, upon the next descent of the cross head, a thin finishing chip is removed from'the breast. Upon the next ascent of the cross head, the heel is moved to its fourth position, during which movement the roll 170 engages the rise of the cam 1'72, which unclainps the heel and allows the spring 150 behind the heel to react and eject the heel from the machine. it will be understood, of course, that in the meantime heels have been fed in turn to the carriers 11, 13 and 1C, and that while one heel is receiving a rough cut by the knife 6? another heel is receiving a finishing cut by the knife 68 so that there is no loss of time as in my prior machines Where a single knife makes successive cuts upon the same heel.
