To all whom it may concern:

Be it known that I, WARREN FRASIER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvanla, have invented certain Improvements in Heel-Breasting Machines, of which the following descripdrawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates, to heel breasting machines and is herein shown embodied in a machine which is intended to breast heels after they have been attached to boots or shoes.

The object of the invention is to provide a machine which is adapted to breast heels quickly and accurately without danger of cutting the soles of the boots or shoes.

With this object in view, the present invention in one aspect contemplates the provision in a heel breast-inn machine of a reciprocating breasting knife arranged to be driven the same dlsta-nce at each stroke and mechanism for clamping a shoe in working position with its heel so arranged in the path of the breasting knife that the latter will properly breast the heel but will not out into the shank of the boot or shoe. In the preferred embodiment of the invention there is I provided a support for sustaining a shoe with its heel in the path of the breasting knife which is arranged for movement in the line of movement of the knife to bring the shoe into Operative relation with said knife. A stop arranged to be engaged by the tread surface of the heel serves to limit movement of the shoe toward the knife and position the shoe with its shank just beyond the range of the knife so that the heel may be breasted without cutting the shank of the shoe. With this arrangement the shoe may be firmly clamped between the shoe support and the stop and in proper relation to the breasting knife before the latter is actuated to breast the heel, which is advantageous in that it insures that the heel will. be more accurately breasted than would be the case if the shoe were loosely sustained upon a jack or shoe support in the breasting operation. The stop which is engaged by the tread surface of the heel is preferably arranged for adjustment in a direction substantially parallel with the line of movementof the range of the knife. Preferably a there.

is provided means for visually indicating the proper adjustments of the stop to respectively suit the standard heights ployed shoes.

' The invention further contemplates the provision of means for moving the shoe support in the line of movement of the knife which is so constructed and arran ed that while the operator may readily e ect any desired movement of the shoe support the latter will remain in any of its positions and is adapted to rigidly resist the thrust of the knife in the breasting operation.

The invention further includes novel combinations of ing and holding the shoe comprising a sup port movable toward and from position un der the knife and toward and from the knife 1n a vertical direction, means for clamping the shoe and means for arresting its movement toward the knife. Preferably, and as shown, the clamping and positioning means comprises a heel engaging member mounted yieldingly for movement with and by the shoe when raised toward the knife and a rigid adjustable stop whereby movement of the shoe toward the knife is limited.

.Other features of the invention will be hereinafter described in the specification and pointed out in the claims.

In the drawings,-Figure 1 is a side elevation of a machine embodying the present in in the manufacture of boots and of heels 'em-' vention; Fig. 2 is a rear view of a portion of the machine shown in Fig. 1; Fig. 3 is a detail view of the last post; Fig. 4 is a view in front elevation, with parts broken away, of the machine shown in Fig. 1; Fig. 5 is a detail view showing the means for limiting the upward movement of the stop.

Referring to the drawings a driving shaft 2 is mounted on the frame 4 and provlded at one end with a driving pulley 6 adapted to be operatively connected to said shaft to impart a rotary movement thereto.

A knife carrier 8, reciprocating vertically in guideways 9, is arranged to be driven the same distance at each stroke. A convenient mechanism for transmitting motion to the knife carrier comprises a crank 10 on one end of the shaft and a link 12 connectingsaid crank to said carrier. A spring 14 having its upper end attached to the frame 4 and its lower end to the carrier 8 may serve to counterbalance the weight of the carrier. A knife 16 is adjustably clamped in a laterally projecting portion of the carrier 8 by the set screws 18. The upper end of the knife bears against the screws 20 which are threaded through a block 22 rigidly secured to or integral with the carrier 8.

A post 24, adapted to sustain a shoe support, is pivoted about a horizontal axis at 26 and arranged for limited swinging movement aboutsaid pivot, the extent of movement being determined by the play of the projection 28 in the depression 30. The post 24 carries a vertically adjustable rod 32 provided with arms 34 and 36 carrying respectively a pin 38 to enter the opening in the heel of a last and a toe rest 40 for sustaining the toe of a last. With this construction it will be seen that the shoe support is adapted to have a swinging movement about the pivot 26 between an outer inclined position in which it may receive a shoe and an inner position in which it may sustain said shoe with its heel properly located in the path of the breasting knife. The rod 32 telescopes within the post 24 and is splined therein as by means of a longitudinal slot 41 in the rod and a plate 43 extending into said slot and secured in the top of the post. A pinion 42 is supported upon the top of the post 24 and has threaded engagement with'the rod 32 so that rotation of the pinion will effect longitudinal movement of the rod. Upward movement of the pinion 42 is restrained by means of fingers 44 secured to the post and provided with projections extending into a eripheral groove 46 formed in the hub of t e pinion. A segmental rack 48 meshes with the pinion and is rigidly secured to a hand lever 50 pivoted to the post at 52 so that by moving said lever the operator may actuate the pinion and raise or lower the shoe support. A stop, herein shown. as a fiat plate 54, is arranged to be engaged by the tread surface of the heel to limit movement of the shoe toward the breasting knife. The plate 54 is arranged for vertical adjustment in order that shoes provided with heels of different heights may be positioned in proper relation with the breasting knife. A holder 56 is mounted in guideways in the frame 4 and the plate 54 is ivoted on said holder to permit it to be ad usted to bring it in para lelism with the face of the work. A set screw 60 serves to hold said plate from movement on the holder away from the work and a spring 59 may be employed to hold said plate against the set screw.

In the machine shown upon the drawings the holder 56 is adapted to be moved into its different adjustments by a treadle 58. The connection shown between the treadle and the holder comprises a rod 61 adjustably connected to a lever 62 which" is connected to theholder by a device to be presently described. A spring 64 tends to hold the treadle 58 in a raised position. The connection between the rod '61 and lever 62 is adapted to permit a yielding pressure to be applied to the holder to move it downwardly. That shown comprises a sleeve 66 loosely mounted on the rod 61, a collar 68 connected to the lever 62 and adapted to be clamped on the sleeve 66, a spring-pressed washer 70 on the'rod 61 and bearing on the sleeve 66 and a nut 72 threaded on the rod 61 below the sleeve. With this arrangement it will be seen that the spring 64 tends to move the holder 56 to its highest position. The connection between the lever 62 and holder 56 is preferably such as to permit the holder to be moved manually away from the work support when desired. It may comprise toggle arms 74, one of which is provided with a handle 76, gravity tending to hold said toggle in closed position. The breaking movement of the toggle will obviously cause the holder to be moved away from the work support.

In order to'secure the plate 54 in its different adjustments to correspond with heels of different heights, adjustable means are provided to limit the upward movement of the holder. In the construction herein shown a triangular recess formed in the frame of the machine opposite the holder and opening downwardly is provided with a series of horizontal shoulders 78 arranged at equal intervals along its oppositely inclined sides. An equal number of openings 80 are formed in the holder 56, each of which is in alinement with one of the shoulders 78 so that a pin 82, if inserted in any one of the openin s, is adapted to engage the corresponding s oulder and limit the upward movement of the plate 54. The openings 80 in the holder are so positioned with relation to the shoulders 78 as to sustain the pin in the positions respectively corresponding with those required for the heights of the standard sizes of heels that are commonly employed in the manufacture of boots and shoes. Graduations to indicate the proper openings for the pin for different heights of heels are respectively arranged on the frame of the machine opposite the corresponding shoulders for said openings, as shown in Fig. 5.

Mechanism to start and automatically stop the rotation of the main shaft so that the crank is rotated through one revolution and the knife carrier is moved down and then up is arranged to be controlled by the treadle 58. Any suitable mechanism adapted to impart a single rotation to the main shaft may be employed and as the same 1s well-known in this art it is not particularly described in this application.

Preliminary to the use of the machine, the operator depresses the treadle so that the. holder is lowered a sutficient distance to enable the pin 82 to be inserted in the proper opening to correspond with the height of heel to be breasted. Upon the re lease of the treadle the holder moves upwardly until the pin strikes the shoulder which is in alinement with the opening that has been selected, when the upward movement of the holder is arrested. The plate 54 carried by the holder is now suitably located to position the shoe which is to be operated upon in proper relation to' the breasting knife so that the heel will be breasted without cutting the shank of the shoe.

In the use of the machine shown, the last which carries the shoe is placed upon the shoe support when the latter is in its outer inclined position. The shoe support is then swung inwardly to position the heel of the shoe in the path of the breasting knife and the shoe is raised by means of the lever 50 so that the tread of the heel strikes the plate 54, and said heel is firmly clamped be? tween said plate and the last. The treadle is then depressed to start the machine, it be: ing understood that the yielding connectionbetween the rod 61 and lever 62 permits this movement of the treadle'even though the plate 54 remains stationary, whereupon the shaft 2 rotates through one revolution and actuates the knife to breast the heel. As the position of the plate 54 has been adjusted to position the shoe with its shank just beyond the range of the breast ing knife, it will be seen that the heel will be breasted without cutting the shank of the shoe. Upon the completion of the breasting operation, the lever 50 is again actuated to unclamp the shoe when the latter may be removed in the usual way, leaving the machine in condition to receive another shoe.

By employing a stop arranged to be engaged by the tread surface of the heel to limit movement of the shoe toward the breasting knife and position the shoe in suitable relation with said knife, it will be seen. that variations in the heights of the different lasts employed to support the shoes does not prevent the shoes from being properly positioned with relation to the breasting knife as might otherwise be the case.

It will be seen that in the machine described although movement may be easily imparted to the shoe support by the hand lever 50 to bring a shoe into and out of operative relation with the knife the fact that this movement is transmitted through a pinion which has threaded engagement with the supporting rod of the shoe support obviates any liability of the shoe support yielding to the thrust of the knife in the breasting operation.

The novel work support, herein described but not claimed, is covered by a divisional application, Serial No. 531,798, filed Decemher 7, 1909.
