HEEL-COMPRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 776,787, dated December 6, 1904.

Application filed August 29, 1902. Serial Nol21,4=73. (No model.)

To El/ZZ whrm't it Duty concern..-

Be it known that I, SANFORD D. LELAND, a citizen of the United States, residing at WVinchester, in the county of Middlesex and State 5 of Massachusetts, have invented an Improvement in Heel-Compressing Machin es,of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings in- IO dicating like parts in the several figures.

This invention relates to heel-compressing machines;v and its object is to provide an improved machine of this class.

An important feature of the invention consists in the combined feeding and ejecting mechanism. In the machine herein shown this mechanism is actuated to clamp a heelblank, carry the blank into position to be compressed, and simultaneously to push the 2 heel that was last operated upon out of the machine and then to unclamp the infed blank and leave it in position to be compressed.

Another feature of the invention consists in providing a compressing-mold comprising a breastplate and means to move said breastplate in the horizontal plane in which the heel is supported to cause it to cooperate with the usual side compressing-dies to compress the heel from front to rear as well as from side to 3 side.

A further feature of the invention consists in so connecting the several operating mechanisms with a single reciprocating table or head which supports one of the dies that said mechanisms are actuated by the movable head. The several mechanisms are preferably each so connected to the reciprocating head that its movement will be retarded or it will remain at rest during certain portions of 4 the movement of the head, and its movement will be accelerated or caused to take place during other portions of the movement of the head, so that said mechanisms will operate in suitable sequence and at predetermined periods in the cycle of operation of the machine. Still other features of the invention relate to the plate which normally forms the bottom of the mold, to the means for supporting it and securing it in position, and to the actuatinafter described, and claimed at the end of this specification.

A preferred form, of the present invention is illustrated in the accompanying drawings, in Which-- Figure 1 is a side elevation of the machine. Fig. 2 is a front elevation of the machine. Fig. 3 is a horizontal section on line 3 3 of Fig. 2, showing the heel-blank holder closed. Fig. a is a vertical section on line 4. {L of Fig. 3 and shows the relative position of the several parts when the reciprocating head is depressed. Fig. 5 is a similar view showing the relative position of the parts at a time when the reciprocating head has nearly completed its ascent. Fig. 6 is a detail view of the heel-blank holder, showing the holder open. Fig. 7 is a sectional view on line 7 7 of Fig. 3. Fig. 8 is a sectional View on line 8 8 of Fig. 6 and shows the same parts as are shown in Fig. 7, but in the position which they occupy when the heel-blank holder has been opened to release a blank. Fig. 9 is a detail View showing the controlling mechanism for the hcelblank holder as seen when looking toward the right-hand side of the machine. Fig. 10 is an enlarged detail view of the controller-cam shown in Fig. 9 as it appears when seen from the right-hand side of the machine. Fig. 11 is a detail view showing the connection between the breastplate and its actuator. Fig. 12 is a sectional view on dotted line 12 12, Fig. 11. Fig. 13 is a detail of the feeding-slide-actuating mechanism, and Fig.1 i a detail of the top-lift plate.

1 indicates the rigid framework of the machine, which supports the actuating mechan lsm.

2 indicates a head which is adapted to be vertically reciprocated in suitable guideways formed in the sides of the rigid frame and hereinafter referred to as the head or the reciprocating head of the machine.

3 indicates the driving-shaft, mounted in bearings in the rear portion of the frame of the machine and provided with suitable fast and loose pulleys. The driving-shaft carries a pinion 1, which engages with a gear 5 on a countershaft 6. The countershaft 6 carries a pinion '7, which engages with a gear 8 on the crank-shaft 9. A link 10 is connected to the crank-shaft 9 and also to a toggle composed of members 11 and 12. The toggle member 11 is pivoted at 13 to a rigid portion of the frame near its base. The other toggle member 12 is pivoted at 14: to the reciprocating head 2.

15 indicates a chute attached to the frame of the machine and adapted to conduct away the compressed heels as they are ejected from the compressing mechanism.

The reciprocating head supports a heelmold which comprises a top-lift plate 10, a breastplate 21, and laterally-movable side compressing-dies 22 22.

25 indicates a heel-seat die removably supported in the upper portion of the frame 1 in alinement with and in position to cooperate with the mold carried by the reciprocating head 2.

The side com pressing-dies 22 22 are removably supported in slides 26 26 and are held in place in said slides by pins 27 27, passed through interlocking ears in the side compressing-dies and the slides 26 26.

The slides 26 are provided with beveled faces 26, and the breastplate 21 is provided with beveled faces 21, cooperating with the similar faces on the slides 26. The faces 21 are provided with undercut grooves 21, while the faces 26 are provided with ribs or lugs 26 shaped to be guided in the grooves 21, whereby when the slides 26 are moved to open or close the sides of the mold the breastplate 21 will also be moved to open or close the front of the mold. This arrangement insures that the members 21 22 22 of the mold shall be actuated simultaneously.

The side compressing-dies and breastplate are actuated to close and open the mold to compress the heel laterally and thereafter to move the slides 26 and force the breastplate 21 and the side compressing-dies 22 22 together to close the mold. The links 30 are slotted at 30 at their connection with the pivot-pins 32 to permit the links to slide with relation to said pivot-pins and allow for lost motion, so that the slides 26 are moved toward and from each other during a portion only of each reciprocation of the head 2.

The pivot-pins 32 are provided with eccentric portions 33 where they pass through the slots 30 in the links 30. Said pivot-pins are adapted to be turned to adjust said eccentric portions in the slots to vary the amount of lost motion. The means shown for adjusting the pivot-pins 32, which project through to the front face of the machine-frame, comprises crank-arms 34, mounted on the squared ends 35 of the pivot-pins. The crank-arms 34 are adapted to be held in adjusted position by means of clamping-nuts 36. (See Fig. 2.)

The direct and positive connection which is provided between the links 30 and the molds 26 requires a minimum of parts and avoids the loose movement between these parts, which has been an objectionable feature of prior constructions, in which dust and pieces of leather were liable to accumulate between the members and interfere with the accurate closing of the mold.

The lost motion connection between the links and frame allows the closing of the mold to be deferred until the latter portion of the rise of the head, and it is also desirable that the mold be opened to release the compressed heel during the first portion of the descent of the reciprocating head in order that as long a period as possible may be provided in which to remove the compressed heel and to feed in an uncompressed blank, as will hereinafter be more fully described, and for this purpose the slotted links 30 are provided with extensions 30, (see Figs. 2 and 3,)on which are mounted rolls 30, and the frame 1 is provided with projections or cams 1, having approximately plane faces 1 and curved faces 1". The cams are engaged by the said rolls 30 as the links are rocked by the head 2 and control the longitudinal movement or lost motion of the links with relation to the pins 32. During the first portion of the rise of the head the slotted links move outwardly on their pivot-pins 32 the length of the slots 30 and are simultaneously rocked on said pivot-pins, so that the rolls 30 pass over the curved face 1 of the cam, and as the upward movement of the head is completed the rolls are carried downwardly outside of the cams 1. At the end of the rise of the head when the mold has been closed the links 30 are in the position shown in dotted lines in Fig. 2. When the head'begins to descend, the rolls are retained behind pivot-pins 32 until a sufficient portion of the descent of the head has taken place to have caused the mold to be opened. At that time the links will have been rocked far enough from the dotted-line position shown in Fig. 2 g to bring the rolls opposite the curved faces of the. cams l, and in the further descent of the head the rolls move over the faces 1, and the slotted links 30 are permitted to slide with relation to the pivot-pins 32 without further opening the mold, and the machine will come to rest with the parts in the full-line positions shown in Figs. 2 and 3. This mechanism for governing the time at which the lost motion may take place insures that the mold shall be opened during the first portion of the descent of the head and shall be closed during the last portion of the rise of the head by causing the lost motion to take place during a period of the downward reciprocating movement of the head different from the period of the upward movement during which it occurs.

It is undesirable that the parts of the mold be separated by the full throw of the links, because that would open the mold wider than is necessary for the removal of the compressed heel and the insertion of the blank next to be operated upon, so that the blank would be liable to get out of position before being inclosed by the mold. Such extra movement would also occasion unnecessary wear on the parts. In the present machine the lost-motion connection between the upper ends of the links 30 and the pivot-pins 82 in the frame is provided for the purpose of permitting the parts of the mold to be separated less than the full throw of the links. The outward movement of the parts of the mold may be limited by the contact of the slides 26 with the sides of the frame 1, as shown in Fig. 2. After the dies have reached the limit of'their opening movement the slotted links slide with relation to their pivot-pins 32 during the remaining portion of the descent of the head,said lost-motion connection permitting the parts of the mold to remain at rest.

hen the reciprocating head 2. is rising, the lost-motion connection of the links 30 to the pivot-pins 32 permits the links to slide with relation to the said pivot-pins, leaving the parts of the mold separated during the first portion of the rise of the head. After the lost motion has been exhausted the links are actuated during the remainder of the rise of the head and move the slides 26 to close the mold. It will thus be seen that the closing and opening movements of the mold take place respectively during the last portion of the rise of the head and the first portion of its descent, so that the mold remains open between its compressing operations during a considerable portion of the cycle of the machines operations to permit the removalof a compressed heel and the insertion of a blank.

The top-lift plate is connected with a post 41 by a bayonet-joint and may be detached from the post by raising it above the side compressing-dies and then turning it on i til it extends at right angles to its normal po sition. The post preferably is forked at its lower end and rests upon the end of a lever 120, (see Figs. t and 5,) which prevents the post from rotating and therefore from becoming detached from the top-lift plate. It is found to be unnecessary to connect the lever to the depending post 41, because the top-lift plate and post are of such weight that they ordinarily descend readily by gravity, and it is moreover found in practice to be advantageous to omit any positive connection between the lever and depending post, because it is the practice to vary the vertical position of the top-lift plate by means of washers w to adapt the machine for compressing blanks of different thicknesses. The lever 120 is a bell-crank lever mounted on a rock-shaft 121, which is journaled in the reciprocating head, and the second arm 122 of the lever is provided with a roll 123, standing in a cam-path 124, formed in the side of the plate 125, supported on the machine-frame. A pivoted latch 126 extends obliquely across the cam-path and is held in this position by a weight 127, acting on the pivot which carries the latch. The latch divides the path 124 into two courses, the lefthand one of which, viewing Figs. 4 and 5, is followed by the roll 123 as said roll moves downwardly with the head 2. This left-hand course, as will be seen from the drawings, comprises a short upper portion through I which the roll moves while the head and mold descend a distance suificient to withdraw the compressed heel from contact with the heelseat die and to permit the side compressingdies to open slightly for relieving the pressure 05 on the sides of the heel, as shown in Fig. 5. The roll then engages the upper portion of the latch and is deflected into the inclined portion of the left-hand course, thereby effecting a turning'of the lever during the first portion 110 of the descent of the head. This turning movement takes place in the direction for raising the top-lift plate relatively to the side compressing-dies, while the head and dies descend until the compressed heel on the top- 15 lift plate is discharged from between the side compressing dies and occupies a position above the upper face of said dies, as shown in Fig. 4:. The course followed by the roll during the last part of the descent of the head I2 is straight and permits the top-lift plate to move in unison with the head and the mold. Near the end of this latter part of the descent of the head the roll 123 comes into contact with the lower portion of the latch, which is pushed I 5 aside as the roll passes it and then is rocked back to its normal position by the weight 127 When the reciprocating head begins to rise, the roll preferably travels first for avery short distance through a straight portion at the bot- I3 tom of the cam-path to permit of the opening of the clamp of the feeding and ejecting mechanism which has been actuated to remove a compressed heel from the top-lift plate and to bring a blank into position thereon. Thereafter the roll is deflected to the right by the lower portion of the latch and while passing through the inclined portion of the right-hand course of the cam-path effects a turning of the lever 120 in the direction for restoring the top-lift plate to its normal position (shown in Fig. 5) below the surface of the side compressing-dies. It is to be noted that the relative upward movement of the top-lift plate during the first portion of the descent of the side compressing-dies discharges the compressed heel promptlyinto position to be ejected from the machine and that the relative downward movement of the top-lift plate during the first portion of the rise of the head enables the blank to be lowered into position to be compressed by the movable side compressing-dies while said dies are yet openwide to receive the blank. In the machine herein shown as embodying the invention there is a lost-motion connection between the side compressing-dies and their actuating mechanism.so that the dies open only far enough to receive the blank readily and the dies remain open to their full extent while the top-lift plate is lowered to its normal position at the bottom of the mold. In that type of machine in which the dies open very wide many of the advantages of this invention, however, would be obtained by lowering the top-lift plate to normal position during the first portion of the closing of the dies and while they were yet open wide enough to receive the blank readily. Therefore by the expression open approximately to their full extent I mean open wide enough to receive the blank freely.

The reciprocating head 2 has a forward extension 2 (seen in Figs. 1, 2, and 3.) which constitutes a table or support for a feeding and ejecting mechanism, which comprises among its parts the slide 60, movable on suitable guides on the table. Heel -blank grasping arms 61 61 are pivotally mounted on the slide 60 and are provided with roughened faces 61 by which to engage the blank.

6 indicates an abutment on the front end of the slide 60, which is adapted to engage the breast of the heel-blank. The arms 61 61 and the abutment 6 L constitute a clamp for embracing and holding a heel-blank (see Fig. 3) while it is being fed into position on the toplift plate 40 and beneath the heel-seat die 25.

The free ends of the arms 61 are provided with abutments or shoulders 66 66 to contact with and push a compressed heel off from the top-lift plate and out of the machine when the slide is moved forward from the position shown in Fig. 5 to the position shown in Fig. 4 to feed an uncompressed heel-blank into position to be compressed.

The adjacent faces of the arms 61 61 oppo site their pivotal connections to the slide 60 are formed as interlocking segmental gears 61. One of said arms has an extension 67, the end of which lies between two lugs 68 and 69 on the slide 60. The lug 68 is soeketed and receives a spring-pressed bolt 7 O, which acts to hold the extension 67 normally against the lug 69 and the arms 61 closed together for clamping a heel-blank. The lug 69 is formed with a channel extending parallel with the spring-pressed bolt to receive asliding block 71, which is adapted to be moved to force the extension 67 of the arm 61 to the left in Figs. 3 and 6 to separate the arms 61 and release a heel-blank.

7 5 indicates a cam-plate supported on a slide 76, vertically movable in suitable ways formed in the side of the table or extension 2 of the reciprocating head 2. (See Fig. 1.) The slide 76 is supported by a pivotal connection at 7 7 with one arm,7 8, of a bell-crank lever fulcrumed at 79 on the reciprocating head 2. (See Fig. 9.) The other arm, 80, of the bell-crank lever is provided with a roll 81, which is received in a cam-groove 82 in a plate 83, attached to the frame of the machine.

The plate 83 is provided with a movable latch 84, located in the cam-groove 82. The latch 84c is fast on a rock-shaft having an arm 85, to which is attached a weight 86. The weight 86 normally holds the rock-shaft in such position that the latch 84 extends across the cam-groove in the position shown in full lines in Fig. 10, but permits the latch to be moved into the position shown in dotted lines in said figure.

The movable latch 84 divides the camgroove 82 into two paths, which are indicated by the arrows in Fig. 10. l/Vhen the reciprocating head 2 is rising, the roll on the arm 80 of the bell-crank lever moves in the path indicated by the arrows in the right-hand portion, Fig. 10, of the groove 82, and when the head is descending the roll moves in the path indicated by the arrows in the left-hand portion of the cam-groove therefor. This cam-groove therefore causes the bell-crank lever, pivoted at 79 to the reciprocating head, to impart to the cam-plate 75 a movement independent of the movement of the head 2 during the first portion of the rise of said head and again during the first portion of the descent of said head, while permitting the cam-plate 75 to move in unison with the head 2 during the latter parts of the upward and the downward movements of the head.

The cam-plate 75 is moved downward with relation to the dies, as above described, as soon as the head begins to rise and 'actuates the sliding block 71 to open the clamp and release a heel-blank, which has been fed into position to be compressed, and thereafter said cam-plate moving with the reciprocating head holds the clamp open during the retraction of the feeding-slide to position for receiving another blank. The acting face of the cam-plate 75 extends parallel with the feeding-slide 60 and of a length somewhat greater than the extent of movement of the slide. The said face of the cam-plate comprises a lower beveled portion and an upper vertical portion. (Shown best in Figs. 7 and 8.) The plate is moved with relation to the feeding-slide 60 from the position shown in Fig. 7 to the position shown in Fig. 8 to engage the sliding block 71 and open the clamp. This movement takes place while the feeding-slide is in the advanced position shown in Figs. 3 and 6. The slide is thereafterretracted to bring the clamp into receiving position, and the vertical face of the plate 75 remains in engagement with the corresponding face of the block 71 during the retraction of the slide and holds the clamp open ready to receive the heel-hlank next to be fed.

The slide 60 is provided on its lower side with ears supporting a roll 93.

94: indicates a bell-crank lever pivoted at 95 in the table or extension 2 of the head 2. The upper arm of the lever 94 comprises two parts 941: and 94 pivotally connected together at 94. The two parts 942 and 9e" are held normally rigid by a shear-pin 94, and the upper part 9a is forked to engage the roll 93 on the slide 60. If, however, the feeding-slide meets an obstruction which prevents its normal movement taking place, the shear-pin 94" will be severed and the partsQ i and 94" will flex, as shown in Fig. 13, and prevent breaking the machine.

The lower arm of the lever 94 is provided with the roll 96. (See Fig. 4.)

97 indicates a link pivotally connected to the frame 1 at 98 and slotted at its upper end at 100 to receive the roll 96. The slot 100 forms a lost-motion connection between the link 97 and the lever 94:. During the first part of the rise of the reciprocating head the roll 96 travels in the slot and the lever 94 is not actuated to move the feeding-slide 60. During the latter part of the rise of the head 2 the roll comes to the end of the slot, and thereafter the lever 94 is actuated to move the slide in the direction to retract the blankholder from the mold. When the head 2 begins to descend, the roll 96 again travels the length of the slot without actuating the lever 94 or causing the slide 60 to be moved, giving ample time for the workman to insert a heelblank into the clamp; but after the roll reaches the lower end of the slot the lever 94: is actuated to move. the feeding-slide 6O forward to present the blank to the compressing-dies.

The driving-shaft 3 is provided with fast and loose pulleys C and 1) and with a flywheel E.

F indicates a belt-shifter carried on a lengthwise-movable rod Gr, upon which is also carried a brake H in position to engage the flywheel and stop the machine when the belt is shifted onto the loose pulley. The rodG is actuated by a rock-shaft K, having one arm, K, engaged therewith and the other arm, K provided with a handle within convenient reach of the operator. The rock-shaft K is also provided with foot-treadles X: 7 1, by means of which it can be actuated in either direction to start or stop the machine by the foot of the operator. These parts constitute a very effective starting and stopping mechanism, which renders the machine completely under the control of the operator at all times.

The operation of the machine is as follows: When the reciprocating head 2 is in its lower position, the several parts of the mechanism occupy the position shown in Figs. 1, 2, 3, and 4, a heel-blank having been fed onto the toplift plate, as indicated in Figs. 3 and 4, and being still held in the grasp of the clamp. WV hen the machine is started, the head 2 begins to rise. The clamp is immediately opened to release the heel-blank by the cam-plate 75, which for this purpose is held approximately stationary with relationto the machine-frame by the cam 82, while the head rises. When the clamp has been opened sufficiently to releasethe heel-blank, the cam 12 1- becomes operative for holding the top-lift plate approximately stationary with relation to the frame of the machine, while the side compressing-dies and breastplate, which at this time are drawn back, rise around the heel-blank, which is supported on the top-lift plate. In the continued rise of the head 2 the arms 61 of the feeding and ejecting mechanism are further separated by the continued movement of the cam-plate 75 to present a clear space between the mold and the heel-seat die 25, and said arms are held in this separated position during the first portion of the rise of the head 2 and during the subsequent retraction of the feeding and ejecting mechanism. The links 30 for actuating the slides 26 move with relation to their pivot-pins 82, and this lost motion permits the side compressingdies and breastplate to remain separated until said parts have risen and surrounded the heel. As the links are moved outward with relation to their pivots 32 the rolls 30 are carried back of the cams 1, as indicated in dotted lines, Fig. 2. During the last half of the rise of the reciprocating head 2 the side compressing-diesand breastplate are moved to close the mold, and the heel which is in the mold between the top-lift plate and the heel-seat die is compressed both laterally and vertically. The feeding and ejecting mechanism is also retracted into position to have a new heel-blank put into the heel-clamp during the last half of the rise of the head.

During the first part of the descent of the reciprocating head 2 the side compressingdies are drawn apart by the links 30, acted upon by the cams 1, and the breastplate is also moved back by its connection with the slides 26. As soon as the dies have been separated sufiiciently to relieve pressure upon the heel the arm 120 of the rock-shaft 121 is actuated by the cam 124 to raise the top-lift plate with relation to the side compressingdies, or, in other words, to hold the top-lift plate approximately stationary with relation to the frame of the machine while the side compressing-dies descend, whereby the compressed heel comes to occupy a position above the side compressing-dies, from whenceit may be ejected. The cam-plate 75 is held stationary while the head descends to permit the arms 61 to close the clamp around the new heel-blank which has been put into the clamp by the workman after the retraction of the feeding-slide. During the latter part of the descent of the head the feeding-slide is moved forward, carries the blank held in the clamp into position over the top-lift plate, and simultaneously with the feeding in of the new blank the abutments 66 on the arms 61 strike against and push off from the top-lift plate the heel which has been compressed, the compressed heel falling into the chute 15.
