than` the distahe. between the boss: 7 and,

coiled spring lines at 46 in Fig. 1. To facilitate said adjustment laterally projecting ears 16 and 17 are formed on the base-plate 1-3, and the rear hinge-lug 15 is likewise lobed at 18, as best shown in Figs. 1 and 4, so that said projections may be conveniently grasped and the required movement effected by the operators hand. rlhe base and press frame being rigid, and the point where pressure 1s applied to the last 10 being above and between the hinged supports 14 and 15, prevents longitudinal play between the die and last members relatively, such as occurs 1n the absence of this rigidity and direct central bearing. This insures a firm and accurate setting of the toe-plate.

Stop shoulders 19 and 20, best shown in Fig. 4, are formed on the lower edge of the hinge-lug 15 to limit the lateral rocking of the last, or anvil member, by abutting against the girder rib 3. The base-bar 12 is preferably reduced in height at its rear end; and carries here a wing-like stop-lug 21 projecting horizontally rearward and offset to the side, opposite to that in which the'last swings,'in a cylindrical curve substantially concentric with the shaft 8; its median edge 22 being parallel with the said, shaft,vr and adapted to cofoperate with the stop 19V and locking means hereinafter described to hold the last member in its upright'position.

Above and adjacent tothe wing 21 a bearing lug 23 juts out from the standard 2, from which point the standard rises vertically at its front, and sup-ports a pressure head 24 bracketed out therefrom to overhang the last nose 13, and provided with a bearing in which a ram or plunger 25 may reciprocate vertically Means for reti-acting and normally supporting the ram at the top' of its stroke comprise a rod 26 vertically disposed in bearing holes through the head bracket 24 and lug 23, with its upper end 27 bent at right angles 'and inserted in an aperture drilled horizontally part way through the ram 25 near its top; and a 28 encircling said rod and compressed between the lug 23 and a stoppin 29 fixed to the rod. Another stop-pin 3() abuts against the bottom of the bracket 24 to limit the upward travel of the rod and ram; but stop collars may be substituted in place of the pins 29 and 30 if desired.

Then the ram 25 is depressed the lower endv of the retractor rod 26 is projected beneath the lug 23, and interlocks with the edge 22 of the stop-wing 21, so that the last member 10 cannot be tilted from its upright position while'a toe-plate is being set. But should the last member be inclined, as shown by dotted lines in Fig. 3, or ,merely tilted ay little from its normal operative position, then the upper face of the stop-wing-21 is` interposed beneath the rod 26, and prevents.

depfeSOn oftheram mechanism. Thus a.

toe-plate cannot be driven without locking the last in its upright position.

For depressing the ram 25 Various known devices are more or less adaptable; but a simple hand-lever 31 is preferred, having a curved cam surface at 32 eccentric or involute to its fulcrum pin 33, and mounted between branches 34 of a forked standard rising from the head bracket 24. The pin 33 is set somewhat forward of the aXis of the ram 25, and the head of the ram is engaged by the cam 32, and forced down las the lever 31 is swung backward and downward to the position shown in Fig. 2. A stqp-lug 35 on the lever 31 abuts against a pair of projections 36 on the respective forks 34, and holds the lever poised as in Fig. 1 when the device is at rest.-

The lower end of the ram 25 is chamfered olf somewhat as at 37, and hollowed out to form a die concavity approximately fitting the convex crown of a toe-plate 38. The toeplate shownv herein is circular in contour, as in Fig. 10,and has three prong-like claws o r tangs 39 bent at right angles to the plane of its edges; but oblong, ovoid and other shapes are made, and can be set by this machine without more than slight changes, if required, in the die end of the ram.

The lower part of the ram shaft 25 is turned to 'a smallerl diameter than its body, so that an abrupt shoulder is formed at 40, and a collar 41 is slidably mounted thereon against the thrust of a helical spring 45 in compression between the collar and the said shoulder. Gripping fingers 42 of small spring wire, at least three of them, are fixedly secured in the lower edge of the collar 41, extend downward along and somewhat below the die end of the ram, and terminate in loops 43. Balls, or heads of other shape can be substituted in place of the said loops, but loops are more readily formed and easily adjusted. pair of short pins 44 driven into the ram shaft, one on each side of the front wire finger 42, serve as a stop beneath the slip-collar 41, and keep it from turning on the ram shaft.v l

To operate the device, a toe-plate 33 is pushed up against the die end 37 of the ram, the wires 42 springing easily outward to receive the plate and snapping back to hold it against the die asin Fig. 7. The last member 10 being tilted as shown in dotted lines in Fig. 3, a shoe 46 is readily slipped over it', whereupon the last. is raised to its upright position, and locked therein by the lower end of the rod 26 directly as the ram begins to be depressed by the hand -lever 31.

As the ram descends the last member "10 to- 12 'may be shifted slightly endwise to prop-- erly place the toe-plate on the sole of the shoe, and then the toe-plate is driven hard -into the sole -as shown in Fig. 8. lVhen the looped ends 43 of the spring lingers strike llO the sole of the shoe 46, they are forced outward by the toe-plate and release it, While the ram descends through the slip-collar tl, thereby compressing the spring 45, Which restores the gripper to its normal position when the ram is retracted.

I further point out and distinctly claim as my inventionl. A toe-plate setter for shoes comprising a retiirn-bentand -laterally oscillable anvil member, and a pressing device having a ram adapted to be reciprocated in opposition to the anvil member, the ram being provid-ed with means for interlocking With the anvil member.

2. A toc-plate setter for shoes comprising a return-bent and laterally oscillable anvil member, a pressing device having a ram adapted to 'be reciprocated in opposition to the anvil member, and a connection to said pressing device adapted to engage said anvil member and to lock the latter on the approach thereto of the ram.

3.
