PEGGlNG-JACK.

SPECIFICATION forming part of Letters Patent No. 372,278, dated October 25, 1887.

(No model.)

To aZZ whom/it may concern.-

Be it known that I, FRANK W. STONE, of Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Boot or Shoe Jacks, of which the following. taken in connection wit-h the accompanying drawings, is aspecification.

This invention relates to mechanisms for holding boots or shoes while the same are being manufactured; and the nature of this in vention is fully described and specifically claimed hereinafter.

Referring to the drawings, Figure 1 is a rear elevation of my improved jack mechanism. Fig. 2 is a sectional elevation of the same.

The last A is supported by a toe-rest, B, and heel-block E, and the toe-rest and heelblock themselves are connected, as represented, with a supporting-block, F. The last is lifted at the toe to put on the shoe, and is drawn back to and held upon the toe-rest by spring a, arranged as shown in Fig. 2. The

' block F has its tang socketed in ahub, H,and

is adapted to permitbeing turned about. The hub H is provided with a flange, b, and is hinged at the point e to a ring,f,'which is secured by screws to the top of post S. The jack mechanism is thus mounted upon the hub H, and the hubis adapted to be tilted on the hinge e, and connected with the hub is a link or lever, a, which travels up and down between the clamps m, and in the clamp is asst-screw, h, that may be turned inward against the link it and clamp it firmly, thus securing the jack mechanism while tilted orinclined onits hinge e at any desired angle. This jack mechanism is designed specifically for usein making shoes by hand, so called, in which practice it is very useful to have the jack mechanism inclined, as set forth.

I am aware that it is not new to support a pegging-jack upon a pivoted base, whereby it may be tilted, and I do notbroadl y claim this.

What I do claim is- In combination, a supporting-standard, S, a hub, H, having a flange hinged to the top of said post, the said hub having asocket, a lastsupporting bracket provided with a tang adapted to enter the socket of the hub and to have movement therein, and a curved link or L guide, n, with clamping mechanism therefor, whereby the last may not onlybe swung upon its tang as a pivot, but may also be inclined by reason of the hinged part H, and its guiding-link, substantially as described.
