Specification of Letters Patent.

Application filed March 14, 1912. Serial No. 683,759.

, tion, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to shoe supports and has for its object to provide a support having improved facilities for presenting the shoe held by it in position to be operated upon.

The invention is herein embodied in a support for holding a lasted and soled shoe in position for the shank to be beaten at each lateral edge downwardly upon the bottom of the last which is at such times within the shoe, the purpose of the operation being to conform the shank of the shoe bottom to the transverse curvature of the last bottom and to compact the materials of the shoe bottom so that in appearance they will present a minimum of thickness. The beating machine illustrated is an adaptation of the machine shown in United States Letters Patent No. 768,560 granted August 23, 190% on my application and in which the operation of the machine is dependent upon the maintenance of continuous contact between the work and the beating tool. One of the problems to be considered in the contemplated use of a beating machine is the reduction of the transmission of vibration through the shoe and support to the treadle upon which the operator must maintain his foot.

One of the features of this invention is found in the construction and arrangement of the connections between the treadle and the jack spindle. The main features of the curvature of the shoe bottom in the shank at either edge and-another valuable charac teristic of the shoe holder is the provision for the heel clasp and the toe clasp each to turn independently about substantially identical axes that extend lengthwise of the shoe Patented Dec.22,11914t.

for adaptation of the clasps to the shape of the shoe. These and other features of the invention will now be described in connection with the drawings and then be particularly pointed out in the claims.

Figure l is a side elevation of a machine in which this invention is embodied; and Fig. 1 is a detail of the treadle connection; Fig. 2 is a perspective view of the shoe holder; Fig. 3 is a vertical longitudinal section of the heel clasp; Fig. 4 is a similar section of the toe clasp.

The column or frame has bearings for the jack spindle 2 the lower end of which is sustained by a toggle 4t, 5 The member 5 being pivoted to the column at 6 and having a horizontal arm 8 is in effect a bell crank or spindle lifting rocker. Underlying the arm 8 is the arm 9 of a rock shaft 11 the other arm 10 of which overlies the rear arm of treadle 12. A spring 15 approximately balances the weight of the jack while a stop 13 limits the extent to which the spindle may be pressed down when a shoe on its last is placed in the holder. The described leverage between the treadle and the spindle affords ample advantage for holding the shoe up to the pounding tool 100 which is rapidly reciprocated by impulses from a rotary actuator as described in United States Letters Patent No. 768,560, and at the same time said leverage connections absorb the vibrations of the shoe holder sufficiently so that there is not an objectionable motion of the treadle upon which the operator must hold his foot while a shoe is being pounded. A spring 16 is confined on the spindle between collars 17, 18, the latter of which is adjustable to vary the compression of the spring. Upon the upper end of the spindle shoe holder upon the table within the limits of the hole in the table. The float has roll- . ers 26, 27, 26 between which is confined and guided the arc-shaped foot 30 of the shoe holder, the same being curved substantially parallel with the curvature of the shank, see Fig. l, of a standard shape of last so that the beating point on the shank is maintained in approximately the same vertical relation to tool 100 as the beating progresses along the shank.

The heel clasp post 32 is secured upon one end of the foot 30 and the toe clasp post l0 upon the other end, each post being made adjustable for the length of the shoe. lhe heel clasp comprises a back plate 34 having .a horizontal stem 35 which is confined but free to turn in a socket in the post. On its lower edge the back plate is formed as an are curved about the stem and rests on a similarly curved shelf formed on the front side of the post to assist in sustaining the weight of the heel clasp and the shoe so that the stem 35 can turn freely. Wing blocks or plates 36 are confined in a transverse guideway in the front face of the plate by acap 38. The forwardly extending padded wings of these blocks 36, which are downwardly and inwardly inclined to form a seat for the heel constitute the heel sustaining members of the shoe holder and they are adjustable from and toward each other by the screw rod 39 for wide and narrow shoes.

The toe post 620 has on the rear side an arc-shaped guide rib curved about an flXlS substantially corresponding with the stem 35 and on which slides a block 42 in which is clamped for vertical adjustment the stem of a toe rest -15 that has limited turning movement on its stem about a transverse pivot 44. The toe post also pivotally supports at 48 the toe abutment 50 which has a thickly padded back face and is movable in a dlrection to engage over the toe end of a'shoe and clamp it down upon the toe rest with suliicient security to retain the shoe firmly in the holder- A handle lever 52 is pivoted on the front side of the abutment by which to lift it into clamping engagement with the toe of the shoe and a spring pressed pawl on the abutment is arranged to engage ratchet teeth in the toe block to lock the abutment in operative position. The head of the pawl is located under the handle lever 52, downward pressure upon winch first lifts the point of the pawl and then swings the abutment to free the shoe. The weight of the handle'lever holds the point of the pawl normally raised but the pivot for the pawl is so located that after the abutment has been clamped down upon the toe by the use of the lever 52 the pawl spring causes the pawl to engage the ratchet teeth and the pressure caused by the reaction of the work maintains the engagement after the handle has been released. A spring 56 returns the abutment to an upraised position after the shoe has been removed. The location oi the pivotal connection between the abutment 50 and the toe post 40 is such that the abutment can clamp shoes of several sizes without resorting to adjustment of the toe post or the heel post on the foot 30.

In the use contemplated in the drawings a lasted and soled shoe, with the last in it, will be dropped into the heel clasp, pushed back, and then pressed down upon the toe rest, the abutment being swung aside for this latter purpose. The handle 52 will then be lifted to clamp the abutment against the toe of the shoe, the direction of movement of the abutment serving to clamp the shoe backwardly into the heel clasp as well as downwardly upon the toe rest and the pawl 54 will lock the abutment while the handle is upraiscd. While the shoe is being applied to the holder the holder will have occupied a position on table 20 most emote from the tool 100. The holder will now be moved across toward the tool and the treadle pressed down to lift the shoe into the field of action of the tool 100 and maintain it there. The operator then tips the shoe by a movement of the foot 30 in its guide 26, 27, 26 and slides the holder on table 20 to present one side of the shank to the tool and then turns the holder around on the table and similarly presents the other side of the shank. Downward pressure on handle 52 will release pawl 54: and tip back the abutment to allow the shoe to be removed. The connections between the spindle 2 and the treadle 12 prevent objectionable jarring of the treadle by reason of the vibration of the tool.
