JACK FOR BOOTS AND SHOES.

SPECIFICATION forming part of Letters Patent No. 336.489, dated February 16, 1886.

Application filed November 5, 1885. Serial No. 181,893. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY T. MoRsE, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Jacks, of which the following is a specification.

My invention relates to lastingjacks; and it consists in improvements in such jacks, whereby they are rendered more convenient for use and simple and compact in construction, and at the same time made strong and free from liability of breakage, all as hereinafter described, and subsequently pointed out in the claims.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of my improved jack. Fig. 2 represents a section on line or m, Fig. 1.

The same letters of reference indicate the same parts in all the figures.

In carrying out my invention I construct the body of the jack in two partsviz., a

' spherical base or ball, a, and a frame, I), having asocket in its lower portion to receive and turn upon a boss, d, formed upon the ball a. A bolt, a, passing through a portion of the frame 2) into the boss d, serves to clamp the frame and ball tightly together when it is not desirable to permit the frame to turn freely on the boss. The ball a is supported by a base, 6, cast or otherwise formed in one piece, as shown, adapted to be affixed to a bench or other suitable support. Said base presents a concave surface or socket, which conforms to the periphery of a portion of the ball. On said base are ears f, to which is pivoted a clamping-lever, 9, one end of which is formed to bear on the ball at a point above its center. Said socket on the side opposite the ears and lever is provided with a projection, c, which projection extends upward above the center of the base and but a short distance therearound. By this construction an open space is left at each side of the base, which permits the frame to be turned to any position .from a vertical to a horizontal on either side,'thus bringing directly upward any part of the sides, toe, or heel of the shoe, and when once the frame and shoe thereon are moved to the desired position the ball can be firmly clamped in the base by pressing the clamping-lever against it. The action of the clamping-lever being on the ball above its center, operates to It represents a cam pivoted to the earsf 6c and bearing against the clamping-lever 9. On said cam is formed a lever, 2', whereby the cam may be turned either to press and hold the clamping-lever against the ball, thus confining the ball and firmly supporting the frame b, or

to release said lever and permit the removal of the ball from the base.

it represents the rest, which supports the toe portion of the last, and Z represents the spindle, which enters the socket on the rear portion of the last. The toe-rest 7c is formed on a straight shank, 7a, which is fitted to slide in agroove, m, formed in one side of the frame I). Said groove is inclined, as shown in Fig. 1, so that the movement of the shank k in it will not only move the toe-rest toward or, from the heel-spindle, and thus adapt said rest to shorter or longer lasts, but will also adjust the toe-rest vertically, so that when it is moved toward the spindle it will at the same time be depressed sufficiently to conform to the height of the last to be supported, and when moved away from the spindle it will b correspondingly raised.

To secure the shank It at any point to which it may be thus adjusted, I provide a clamp or plate, 0, formed at its upper end, 0, to project over the upper edge of said shank, as shown in Fig. 2, and having a slot, 19, through which passes a bolt, q, whereby the plate 0 is secured to the frame I), said slot and bolt permit-ting the plate to move vertically.

1- represents a cam pivoted to cars on the lower end of the plate 0, and formed to bear against a part of the frame I) under the plate 0. Said cam has a handle, r,whereby it may be turned, so as to draw the plate 0 down wardly, and thus cause it tobind the toe-rest shank or to loosen said plate so that the shank may be moved. The spindle Z is attached to a block, 15, which is pivoted at u to the frame I), and is normally pressed by a spring, 1), so that the spindle Z has a tendency to swing toward the toe-rest, and thus press the toe of the last against said rest. The spring 12 is constructed to act by contracting, and is attached a assess at one end to an arm, 26, on the block it, and at the other end to the frame 1), suitable openings being formed in the arm and frame for the reception of the spring. The spring may be attached to the frame, so as to bear against the block 15, as shown by dotted lines, instead of being secured to the arm t, in which case said arm may be omitted.

It will be seen that the operator can, by means of the ball a, socketed base 6, and clamp g, secure the jack at any desired inclination or in a horizontal position at either side of the base, and can rotate the frame I) on the boss (I, so as to cause the last to stand in any desired direction.

These capabilities of adjustment, together with the simultaneous longitudinal and vertical adj ustability of the toe-rest, enable the operator to put the last in almost any position desired, and make the jack very convenient.

The construction is simple and compact and of such nature and the form is such as to make the jack strong and free from liability to breakage.

I do not limit myself to all the details of construction herein shown, but may modify the samein some minor particulars. For example, a screw or other clamping device may be used, instead of the clamping-lever g and cam h, to hold the ball.

I claim- 1. The combination of the frame I), having lastsupports at its upper end, the ball swiveled to the lower end of the frame, so that the frame can rotate independently, the fixed socketed base provided with a projection, e, and ears f, opposite said projection, open spaces at both sides of the base, which permit the frame to be adjusted in any position from a vertical to a horizontal, and adjustable clamping mechanism connected with the ears f,-as set forth.

2. The combination of the frame b, having last-support at its upper end, the ball swiveled to the lower end of the frame, so that the frame can rotate independently, the fixed socket'ed base provided with the projection 6, open spaces at both sides of the basewhich permit the frame to be adjusted in any position from a vertical to a horizontal, and adjustable clamping mechanism, substantially as described, arranged to bear on the ball at a point above its center, as set forth.

3. The combination of the frame having the last-supports, the ball swiveled to the lower end of the frame, so that the frame may rotate independently,the clamping-bolt c, whereby the frame may be made fast to the ball, the socketed base,and mechanism, substantially as described, for locking the ball to the base, as set forth.

4. The combination, with the frame I), having an inclinedgrooveorguide, m, the spindle Z, supported by said frame, the shank 7c, having the toe-rest k, and fitted to slide in said groove, and thus effect the simultaneous longitudinal and vertical adjustment of the toerest, and means for securing said shank in any position to which it may be adjusted, as set forth.

5. The combination of thejack having the last-supports Z k, and the ball a, the socketed base 6, the pivoted clamping-lever g, and the cam h, and its lever i. as set forth.

In testimony whereof I have signed my name to this specification, in the presence oftwo sub scribing-witnesses, this 2d day of November, 1885.

HENRY T. MORSE.
