JACK FOR BOOTS OR SHOES. V

SPECIFICATION forming part of Letters Patent No. 764,335, dated July 5, 1904. Application filed November 27, 1903. Serial No. 182,758. (No model.)

To all whom it may concern:

Be it known that I, ZOTIQUE BEAUDRY, a citi- Zen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Jacks for Boots or Shoes, of which the following is a specification.

This invention relates to an improved jack for holding' boots and shoes, the same being particularly adapted for use in connection with machines for trimming, burnishing, or setting the edges of the soles and heels of said boots and shoes.

The object of the invention is to provide a vjack which can be readily adjusted to hold boots and shoes firmly in position to be operated upon, the device being so constructed that the shoe can be held with either the toe or the heel uppermost and adapted to hold said shoe so that it may be rotated or rocked into different positions.

The invention consists in the combination and arrangement of parts set forth in the following specification andv particularly pointed out in the claims thereof.

Referring to the drawings, Figure 1 is a side elevation of my improved jack with a shoe clamped thereto with the toe pointing upwardly, the same being illustrated fastened to a portion of a supporting-frame, said supporting-frame being broken away to save space in the drawings.` Fig. 2 is an enlarged section taken on line 2 2 of Fig. 1. Fig. 3 is a side elevation of a portion of the jack with the shoe-holder and the collar and arm to which it is connected shown separated. Fig. 4 is a side elevation of a portion of the jack with a shoe clamped thereto, the heelbeing uppermost. Fig. 5 is an enlarged section taken on line 5 5 of Fig. 1.

Like numerals refer to like parts throughout the several views of the drawings.

In `the drawings, 10 is a U-shaped jackframe fast to and supported upon a frame 11 of any suitable construction. The vertical arm 12 of the jack-frame has a shoe-support 13 rotatably mounted thereon, said shoe-support being provided with a cylindrical shank 14:, constructed to rotate in the upper end of the arm 12 and prevented from moving longitudinally therein by a screw 15, the inner end of which projects into a groove 16, liurovided in the shank 14. A rotatory clamp-slide 17, cylindrical in cross-section, is mounted to slide in ways 18, provided in the upper end of the vertical arm 19 of the ljack. A collar 2O is fast to the slide 17 between the arms 12 and 19 of the jack and is guarded from longitudinal motion upon said slide by a screw 21, the inner end of which bears against the slide 17.

In Figs. 1, 2, and 3 a fore-part holder 23 is mounted upon the slide 17 and is detachably connected to the collar 2() by a swing-plate 24, the left-hand end of which is supported upon the screw 21 and heldagainst the collar 20 by a spiral spring 25, which encircles said screw 21 and bears at one end against the plate 24 and at the other end against a washer 26, located beneath the head of said screw. A pin 27, fast to the fore-part shoe-holder 23, projects through a slot 28, provided in the plate 24C. The fm'e-part holder 23 is bored out to receive the cylindrical slide 17 and beyond the right-hand end of said slide to receive aspiral spring 29, one end of said spiral spring 29 bearing against the end of the slide 17, the other against the bottom of the recess 30 in the shoe-holder 23. The holder 23 is provided with a downwardly-extending arm 31, to the lower end of which is pivoted at 32 a lever constituting a heel-lwlder 33. The right-hand end of the heel-holder 33 is curved to lit and partially encircle the heel of a shoe 34, clamped to the support 13 by the fore-part holder 23, hereinafter described. The opw posite end of the heel-holder 33, at the left of the pivot 32, is provided with a segment 35,

havinga corrugated surface e6, which engages bell-crank lever 4:1 engages a forked bracket IOO 43, rotatably mounted upon the slide 17 said bell-crank` lever /projecting between the arms of said forked bracket and being rounded on its opposite edges to engage on the right thereof said bracket and on the left a frictionroll 44, journaled to rotate upon said bracket. The bracket 43 is fastened to the slide 17, in such a manner that said slide is free to rock in said bracket, by a set-screw 48, which projects at its inner end into a groove 9.9., formed in the periphery of the slide 17 The pressure of forcing the slide 17 `toward the right -in order to clamp a shoe to the shoe-holder is taken by a shoulder formed upon the slide 17 and bearing against the right-hand side of the forked bracket 43. r1`he screw 43 keeps the bracket 43 and slide 17 together when the slide 17 is being withdrawn from the shoe or moved toward the left. The horizontal arm of said bell-crank lever is pivotally connected to a treadle-rod 45, which extends downwardly and is connected to a suitable treadle. (Not shown in the drawings.) Said rod is depressed by the treadle and raised by a spiral spring 46, fast at one end to said rod 45 and at the other to the jack-frame 10.

When the shoe is removed from the machine, the fore-part holder 23, heel-holder 33, and collar 20, together with the depending arms 38 and 3l, assume the positions relatively to the jack-frame illustrated in Fig. 3, said collar and shoe-holder being forced apart by the action of the spiral spring 29, and thus disengaging the corrugated surfaces 36 and 37, allowing the heel-holder to drop into the position shown, with the pin 40 resting against the arm 31. ln placing the shoe in position for the edges of the sole to be operated upon, said shoe is placed in the machine in the position indicated in Fig. 1, with the toe uppermost and the fore-part holder bearing against the upper of the shoe midway between the toe and shank thereof. The heelholder is free to be rocked upon its pivot, as shown in Fig. 3, and is tipped upwardly until the right-hand end thereof firmly engages the heel of the shoe 34. The operator now places his foot upon the treadle and depresses the treadle-rod 45, rocking the bell-crank lever 41 upon its pivot and moving the slide 17 together with the collar 20 and its depending arm 38, toward the right, Fig. 1, until the corrugated surfaces 36 and 37 engage one with the other, and thus lock the heel-holder 33 firmly in position, while the shoe-holder 23 is brought to bear against the toe portion of the shoe. The shoe is now in position to have the edges of the sole trimmed or burnished, as the case may be, it being understood that the shoe-holder 23, heel-holder 33, arms 31 and 38, collar 20, and slide 17 are free to be rocked backward and forward, said slide 17 rocking in the bearing 18 and forked bracket 43 and the shoe-support 13 rocking with them. 1V hen it is desired to operate shoe-holder 23 is removed by springing the plate 24 outwardly until it disengages the pin 27 and slipping said holder off of the slide 17. A holder 47, Fig. 4, is then placed upon the slide v17 and is held thereon by the plate 24 and pin 27, the end of said holder 47 bearing against the inside of the heel of the shoe. Said shoe is clamped to the support 13 by means of the slide 17, as hereinbefore described.

It is evident that instead of the corrugated surface 37 a single tooth might be used without departing from the spirit of my invention, said tooth being constructed to engage the corrugated surface 36.

Having thus described my invention, what I claim, and desire by Letters Patent to secure, is-
