HEEL-COMPRESSING MACHINE. 7

Specification of Letters Patent.

Patented July 21, 1914.

Application filed July 23, 1907. Serial No. 385,146.

To all whom it may concern v Be it known that I, EDWARD ERICKSON, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Heel- Compressing Machines, of which the following is a specification.

This invention relates to heel-compressing machines, and its objects are manifold.

The principal object of the invention is to compress all parts of a heel simultaneously and this is accomplished by providing complemental tread and heel seat dies, complemental side or edge dies, and a breast die, all of which are so constructed and arranged as to be actuated by a movement of a reciprocatory head. Of these elements especial importance is given to the side and breast dies which utilize the power of the machine most advantageously in compressing the heel from front to rear.

Another novel feature is the utilization of a pair of compressing members as a heel carrier which not only places a heel in compressing position but which subsequently takes the place of an ejector, by removing the heel to a discharge openingthrough which it may gravitate to a suitable receptacle. Other novel features in the construction and operation of the invention are hereinafter described and claimed, and illustrated on the accompanying drawings forming a partof this specification of which,

Figure 1 is a front elevation of a compressing machine constructed in accordance with the invention. Fig. 2 is a right side elevation thereof. Fig. 3 is a plan view in section of the power-transmitting mechanism. Figs. 4, 5 and 6 are details of the clutch-controlling mechanism. Fig. 7 is a vertical section on a larger scale of the compressing mechanism in normal or receiving position. Fig. 8 is a similar view of the same mechanism in compressing position. Figs. 9 and 10 are plan views, partly in section, of the same mechanism as it appears respectively in Figs. 7 and 8. Fig. 11 is a front elevation partly in section of the mechanism as it appears in Figs. 8 and 10.-

Before proceeding to the description of the machine it should be understood that the names and terms employed therein are not intended to limit the invention, but are solely for the purpose of designating the several elements and their functions.

The same reference characters indicate The said support and vcrosshead are provided, as usual, with a pair of cooperative compressing members, hereinafter described, between which a'heel is to be compressed. The support or bed, as it will be hereinafter termed, is supported by and between the upstanding sides 12, 12, which are formed on the bases 14, 14, of the frame. The crosshead 20, as illustrated, is above the bed 10, though the order might be reversed, and its ends, which have guiding flanges 15, 15, extend through slots in the sides 12, 12 in which the ends have sliding bearing. Cylindrical projections 16, 16 formed on the ends of the head 20 are connected respectively by links 17, 17 to a crank shaft 18 suitably journaled in hearings in the base portions 14, 14 of the frame. The head 20 is moved toward and from the bed 10 by r0- tating the shaft 18, and in order to properly rotate the shaft the machine is provided with a convenient form of power-transmitting mechanism hereinafter described.

As previously stated the bed 10 and head:

20 are provided with cooperative compressmg members. These members may be individually termed a tread die 19 and heel seat die 21, inasmuch as the former enga es and flattens the tread of a heel, and the" latter engages and forms that surface of The tread die 19 is in realnot absolutely necessary, it-is preferable to have the die 19 stationary'and the die 21 movable, and they are therefore mounted movable toward and from the support.

respectively on the bed and head as clearly shown in Figs. 7, 8 and 11. The member 19 is immovaloly installed in a depression in the bed so that its work-engaging surface lies flush with that of the bed. The member 21, however, is adjustably mounted byreason of being afiixed to a die seat 22" having flanges 23 by which it is clamped to the head. Prior to clamping the die seat 22 in place, it may be provided with a heel seat die of any desired size or shape having dowel holes. to receive the dowel pins 24:, and a screw thread hole by which it may be drawn up to the seat with a screw 25 set into the seat. The whole may then be slipped into a depression in the head, and clamped in the correct position by the screws 20 and clamping strips 23 which overlap the flanges 23. In Figs. 1, 7, 8 and 10 it will be seen that there is a nose 26 which is a compressing member in itself for it is adapted to engage the breast of a heel 100. The nose 26, hereinafter termed a breast die, is of greater depth than a heel, and so the tread die 19 is provided with an aperture 27 to receive the breast die so that the heel seat die may approach as closely as necessary to the tread die. The heel seat die is of convex form so as to shape a heel in conformity with the heel seat of a shoe, and it will be seen in Figs. 7 and 8 that the median line of the work-engaging face thereof is inclined relatively to the head. The sliding bearing which the head has in the sides 12 of the frame, guides the head so that it moves perpendicularly toward and from the bed 10, and so the median line of the heel seat die and also the surface of the tread die 19, is inclined relatively to the direction in which the die moves. The

work-engaging surface of the breast die and the back face 4L6 thereof are also inclined to their direction of movement, all of which is hereinafter explained.

The combined heel-carrying and compressing mechanism, h ereinbefore mentioned, comprises primarily a pair of compressible dies 30, 30 adapted to engage the side and rear edges of a heel. These dies are movable in unison to and from the point of compression between the tread die 19 and heel seat die 21, and are also movable toward and. from each other so as to be adapted to compress the sides and rear of the heel. Vhile their principal function is that of compressing, they are instrumental, by reason of their unitary movement toward and from the point of compression, in acting as a carrier for carrying a heel to and from the said point. In order to utilize the dies 30, 30 as a heel carrier they are preferably mounted on a carriage 31 which is mounted so as to move back and forth in guides 32 on a receiving table 33. A convenient method of mounting the dies 30, 30 so that they shall be compressible is to pivot them on the car riage. In the form herein illustrated, they are provided with ears 34: which fit snugly in a recess in the carriage and which are pivoted on astud 35 common to both. See Figs. 7 and 8. Each member 30 constitutes a half-die, and both together form an orifice which in plan view conforms to the plan of the shape to which the heel is to be compressed. The method by which the be inserted between the point of compression.

members 30 are mounted makes it a simple matter to substitute others designed to give to a heel a different shape or size. A spring 36 occupying pockets 37, 37 formed in the inner faces of the members 30 near the pivot 35, serves to normally separate the members on a line corresponding to the median line of a heel (see Fig. 9). By reason of so mounting the die members they are adapted to receive a heel blank from above, and by reason of separating them and enlarging the passage between them a heel is free to gravitate therethrough unless supported by other means. For the purpose of supporting a heel in the dies, the carriage is provided with a plate 38, and means adapted to cause the plate to alternately cover and uncover the passage through the dies. A convenient method of accomplishing this end is to utilize the movement of the carriage toward and from the point of compression. The plate 38 lies between the carriage and the table 33 and is adapted to have sliding contact with each. The plate is frictionally connected to the carriage by a stud 39 extending through a slot 1O formed in the plate parallel to the direction of travel of the carriage. The stud has a head 4L1 overlapping the sides of the slot 10, and drawn toward the plate by a spring 42 compressed between the carriage and a nut and washer 1-3 on the other end of the stud. By this means the plate is frictionally clamped with yielding tension against the carriage, so that it is adapted to either move with it or permit movement of the carriage relatively thereto within the limits of the slot. A friction washer may or may not head 11 and the plate 38.

The operation of the carrying and compressing mechanism is as follows. \Vhen the machine is in a state of rest, the said mechanism is as illustrated by Figs. 1, 2, 7 and. 9. Referring now to Figs. 7 and 9, it will be seen that the head 20 bearing the heel seat die 21 and breast die 26, is relatively distant from the tread die 19, and that the compressible members 30, 30 of the heel carrier are in receiving position, also relatively distant from the tread die and The dies 30, 30 are here separated by the spring 36 so that their rear shoulders abut against the carriage as shown in Fig. 9. A heel 100, placed tread first into the passage between the dies 30, 30 in this position, is supported therein by the plate 38 which now underlies the passage. The power-transmitting mechanism, hereinafter described, is then brought into operation so as to advance the heel carrier toward the point of compression, and to actuate the several compressing members. As the carriage 31 and die members 30, 30 advance, the plate 38, by reason of its fric tional connection with the carriage also advances, still supporting. the heel in the dies.

On their way to the point of compression,

latter to push the heel from the now stationary plate 38 to the inclined work-engaging face of the tread die 19, the stud .39 meanwhile advancing in the slot 40 of the. plate. Having arrived at the point of com pression the heel is tilted by the tread die so that the median line of the former is inclined to the movable work-engaging dies and to their directions of movement. By reference to Figs. 8 and 10 it will be seen that the plate 38 is now retracted relatively to the opening in the dies 30,30.

After the last named dies arrive at the.

point of compression the slowly approaching heel seat die 21 and breast die 26 enter between the former dies, and engage respectively the top 6 and breast c of the heel.

I By reason of the inclination of the workengaging face ofthe breast die, it crowds the heel toward the rear of the dies 30,30, thereby. compressing the breast 0 and rear 4% oftheheel. The rear face 46 of the breast die is also inclined to its direction of movement but oppositely to the work-engaging face thereof. This face 46 is adapted to engagethe inner faces ofprojecting portions 45, 45 formed on the, dies 30, 30 and so to slightly wedge the side dies forward and restrain the dies against tendency to retro-i grade movement, due to the pressure exerted on the heel by the breast die.

Simultaneously with the cooperation of the compression members 19, 21 and 26, the dies 30, 30 are closed by suitable means so 'aEIS to shape the side edges and rear portion of the heel. The means for accomplishing this may be of any preferred form, that illustrated'having a pair of sliding pressure blOCKS 51, 51mounted on the bed lO and connected to the head 20 so as to be actuated (Fig. 11) and are connected by pivoting studs 53 to ltoggleulinks 54, 54 which in turn are pivotallyconnected by studsv 55, 55 to brackets 56, 56 formed on thehead. By reason of this connection the head, as it approaches and leaves the bed, causes. the blocks to alternately approach and ,recede relatively to each other. As shown in Fig. 11 the heel seat die 21 is of just such size as to. be admitted between the side dies 30, 30 when the latter are closed. In practice thesev three members are. preferably combined in sets varying collectively in size and style, and are attached or detached as a whole. l/Vhen the head 20 again recedes from the bed the carriage 31, together with the dies 30, 30 and plate 38, is retracted to. its former receiving position shown in Fig. 7. The plate 38 being retracted relatively to the passage between the, dies 30, 30 again moves in unison therewith and the latter, being now released and separated, retracts the compressed heel by means of the projecting portions 45, 45 of the dies. Continued movement of the carriage causes the plate to uncover the discharge opening 44 in the table 33, and causes the portions 45, 45 to move the heel to the said opening through which it is now free to gravitate. See Fig. -7. It is immaterial what becomes of the heel but it may be presumed that it drops into a receptacle (not shown) below the table. Before the carriage reaches its former receiving position the plate 38 engages another stop which arrests its movement and returns it to its former position relatively to the carriage and dies 30, 30.;

This stop is shown as consisting of a pair, of

screws 48 set into thefront edge of the table 33. See Fig. 10.

The description has so farcovered a complete cycle of movements of the'compressing and carrying mechanisms, and while the mechanism for actuating the former forms no part of the invention, a brief description will make it somewhat clearer. The crank shaft 18 which effects the reciprocation of; the head 20, also effects that of the carriage 31. For this purpose the shaft is provided with a path cam 60 whose path is occupied by a roll 61 mounted on a lever 62. One end of the lever is pivoted on a fixed shaft 63 mounted in the two base portions 14, 14, and the other end, which is connectedto the carriage 31, has two forked extensions 64, 64 each formed with a radial slot 65. The carriage 31 has two bosses. or arms 66,- 66 which extend through slots 67', 67 formed in the table, and which are connected by a rod or shaft'68' which passes through the slots in the'extensions 64, 64. Thezlever 62 is oscillated by the cam 60 so as to reciprocate the. carriage in correct relation to the reciprocation of the head 20.

Rotation of the shaft is effected by a, gear 70 affixed to. the'cam 60 and driven by, a pinion 71 afiixedvupon a countershaft 72.

&

See Fig. 3. bearings 73 in the bases 14;, 1 1 and is provided with a gear 74 which is driven by a pinion 7 5 affixed upon the primary power shaft. 76 also journaled in bases 14, let by bearings 77, 77 The shaft 76 is provided with a continuously rotating loose pulley 7 8 having an annular internally tapered friction ring 79, and with a tight conical clutch member 80 adapted to have frictional driving engagement with said ring. The shaft 76 is also provided with a tight momentum wheel 81, and a controller 82 adapted to be manually actuated so as to force the loose pulley with its ring 79 into engagement with the tight member 80. Figs. 3, at and 6 illustrate a cylindrical. cam member 83 which surrounds the shaft 76 and which is pinned or otherwise secured to a fixed support such as the bearing 77. The member 88 has inclined end faces 84 which are adapted to cooperate with correspondingly inclined faces 85 formed on one end of the controller 82. The controller also has a segment of gear teeth 86 which intermesh with a gear segment 87 affixed to one end of a rock shaft 88 journa'led in bearings in the bases 14, 14:. The arm of the segment is pivotally connected to one :end of a link 89 whose other end is pivotally connected to a hand lever 90 pivotally mounted on one end of the shaft 63 and held thereon by a collar 91. The lever 90is adapted to be manually actuated so as to cause the segment to oscillate the controller 82. When the controller is oscillated in one direction it is caused, by its engagement with the inclined faces 84 0f the member 83, to more endwise on the shaft 76, and to engage the hub of the loose pulley 78 and force the ring 79 of the latter into driving relation with the cone member 80. In order to hold the parts in this relation, the hand lever is provided with a spring-pressed latch 92 which engages a toothed sector 93 secured to the frame 12. The rock shaft 88 may be provided with an arm 94 and a spring 95 connected thereto so as to exert on the rock shaft a tendency to return the controlling means to inoperative position. The rock shaft may also be provided with an arm 96 carrying a stud 97 and brake shoe 98 thereon adapted to engage the periphery of the momentum wheel 81 when the controlling means is in inoperative position.

In Figs. 1 and 2, the journals of the crank shaft 18, are shown as having removable lower caps 99 formed with screw-threaded shanks 101. The latter are provided with -nuts 102 which have suitable seats in the base portions 14, ltand which are adapted to lock the caps against their journal boxes in the frame.
