SHOE-PRESSING DEVICE.

Application `filed July 2,

ture adapted to be heated for themore effective compacting and adhering of the rubberized shoe parts. Y.

Of the accompanying drawings:

Fig. 1 is a side elevation of the improved device in its preferred form and a lasted shoe in place therein, parts beingr sectloned and broken away.

Fig. 2 is a plan view of the sole-press1ng structure and adjacent parts.

Referring to the drawings, is a ram cylinder in which is mounted a ram 11 carrying on its top a plate 12 which supportsl the sole-pressing members. Rising integrally from one side' of the cylinder 10 1s a bracket 13 of which the upper end portion extends laterally over the cylinder and has pivoted thereon at 14 an L-shaped holddown member 15 of which one arm is adapted to bear upon the toe portion of a shoe 16 mounted upon a last 17 and of which the other arm is adapted to bear upon the shank of the last to hol-d the last and shoe against the upward pressure of the sole-pressing members when the latter are raised by the ram.

The sole-pressing structure comprises a heel-pressing block 18 and a toe-pressing block 19 each mounted with a ball-andsocket connection upon a hollow stud A20 mounted in and projecting upward from a plate 21 which is secured upon the upper face of the plate 12 by screws 22, 22. A screw 23 has its head in the hollow stud and is screwed into the under side of the block, 18 or 19, theupper end wall of the stud being apertured to accommodate the screw with substantial tolerance so as to permit ball-and-socket movement of the block upon the stud and a compression spring 24 is interposed between the plate 21 and the block to maintain the latter with its shaped upper face in substantially complemental 192.6. Serial No. 120,137.

relation to the toe portion, or the heel portio-n., as the case 'may be, of a shoe placed upon the sole-pressing structure without substantial pressure. The heel-pressing block 18 and ithe toe-pressing block 19 are thus adapted to be pressed against the work without yielding as a whole with relation to the plate 21, but are adapted to turn upon their respective studs 20 to .fit against the work and apply subsantially equal pressure thereto throughout their extent.

The 'sole-pressing .structure between the heel-pressing block -18 and the toe-pressing block 19 comprises several sectional- pressing blocks 25, 26, 27, 28, 29, each formed in its 'lower face with a cylindrical recess such as the recess l30 in which slidably lits a vertically aperturedand counterbored stud 31. A screw 32 in each stud retains the block thereon While permitting sliding vertical movement of the block, and a` compression spring 33 is interposed between the plate 21 and each of these intermediate blocks, to press the block firmly against the Work notwithstanding such non-conformity as ma occur between the adjacent face of the worl; and the group of blocks as a whole. p

The several blocks are held in spaced relation by lateral studs- 34, 34 projecting from one block into contact with the adjacent block, thestuds thus being adapted to hold the several blocks against rotary movement about their respective studs 31. i

The several blocks and adjacent parts obviously are preferably ot rigid and heat conductive material and they may be heated in any' suitable manner in order to provide a more effective compacting and adhering of the parts of the shoe, as by mounting an electrical heating elementV 35 under the plate 12. y p

In the operation of the device, the ram 11 being lowered, the work is placed upon the so as to press the work with substantial uniformity throughout their extent.

The intermediate blocks 25 to 29 are perf.

mitted bythe springs 33 to yield individually, so as to conform asu group to the contour of the Work, and yet to apply adequate pressure locally to their respective parts of the Work.

When the pressure has been maintainedfor u suicient time to eiect the desired result upon the Work the ram is lowered, the work removed, and the operation as described is repeated.

My invention is susceptible of modification within its scope' and I do not 'wholly limit my claim to the specific construction shown.

I claim:

A shoe-pressing device comprising a plu-v rality oflocks of rigid material adapted concurrently to press respective adjacent parts of the Work and' means for pressing the work against the blocks, yielding back ing means for the blocks permitting one to yield with relationv to another under 'the
