' IMPROVEMENT m HEEL-AND EDG E POLISHINGMACHITNES FOR BOOTS AND SHOES. I

V Specification forming part of Letters Patent No. 174,23 1, dated February 29, 1876 application filed I January 3,1876.

To all whom it may concern Be it known that I, LEoPoLDGRAF, of

Newark, in the county-of Essex and State of for the sole-are operated by one and the same driving-shaft, in such manner that bfb'th operations may be carried on at the same p The invention also consists of a simpler and better contrivanceof the gear by which the polishers are operated; also of' an arrangement for obtaining a better action of the polishers, and a higher speed of them for a given speed of the driving-shaft than heretofore obtained; also of an improved contrivance for gaging the polishers to edges of different thicknesses, and also of an improved shape of the clamp-frame for holding the shoe, all as hereinafter described.

Figure 1 is aside elevation of my improved machine. Figs. 2 and 3are elevations of the two ends. Fig. 4. is a horizontal section taken 7 online as a; of Fig. 1. Fig. 5 is a sectional elevation taken on line y y, and Fig. 6 is a section on line 2 z of Fig. 1. t v

Similar letters of reference indicate corresponding parts.

A is the driving-shaft, which is mounted in the standards B above the top 0 of the frame, and has a short crank at each end working in a sliding box, .-D, fitted in a slotted-polisher carrier, E, which swings on a pivot, F, in the top of the standard B, and carries a polisher,

G or H, at its lower end.

The polisher may be rigidly'attached to the carrier, as at G, but I prefer to fix it on a pivot, I, inthe lower end of the carrier and connect it' by an arm, J, and rod or bar, K.

with a stationary object at L, so' that 'it is made to rock on its pivot I at the same time that it swings, thus increasing the speed of .the polishing surface, and alsoobtaining a better action on account of the small circle of the face of the polisher which may be used in such arrangement, and which gives better results than when made on a largecircle to correspond with the radius of the carrier.

M is an adjustable gauge combined with the polisher and ..fixed to slide along its face for gaging it to soles of different thicknesses, being fitted to slide forward and backwardon the pivot I, on which it also swings, to correspondwith the swinging of the polisher. It has a forked projection, N, embracing the stud T, to' cause it to turn on pivot I, and it has a spring, 0, to push it back and a camblock, P, acting on the projection N to push it forward, and'the cam-block is connected to a hand-lever, Q, forworking it.

It is a rest for the hands of the attendant to bear against when holding the toe of the sole up to the polisherby hand, to enable him to hold the shoe steadier than he could without it.

For polishing the edges of the soles the [boots or shoes will preferably be held by hand,

but for polishing the heels they will be held in a clamp, S, which is connected by the ball and socket joint U, fixed in the vibrating frame W so as to be pressed back to make the bottom of the heel press'firmly against Y the lip y of the polisher. The frame vibrates to raise the heel up to the polisher and lower it away again, and the'ba-r V is pressed back by the weighted-lever a acting on it through the toggle-piece d and bell-crank b. The I weighted-lever on also raises the boot or shoe up against the polisher. and holds it there while being polished and the foot-lever 0 brings it down again. I

f is a sole-plate fitted on one of the bars of the clamp-frame for the sole of the shoe to have a fair bearing on when clamped in the frame.

Havingthus described my invention, I claim as new and desire to secure by Letters Patent 1. A polisher, pivoted at lower end of its 3. Thegagc.
