IMPROVEMENT IN HEEL-TRIMMING MACHINES.

Specification formingpart of Letters Patent No. 135,745, dated February 11, 1873.

To all whom it may concern:

Be it known that I, CHARLES J. Annv, of Boston, in the county of Su'ol'k and State of Massachusetts, have invented a certain new and useful Improvement in Heel-Trimming Machines, of which the following is la specifi* cation:

Nature and uObject of the Invention.

-to any desired pattern.

Description of the Drawing.

Figure is an elevation of my machine. Fig. 2 1s a perspective view of the same. Fig. 3 is a front elevation of a part of the same.

General Description.

A B O represent the frame to which the several parts of the machine are attached. K Kl K2 is a slide workin g vertically on the upright A. This slide K has arms K1 K2, Fig. 3, which serve as housings for the swinging fra-me G1 G2, Fig. 3. G, Figs. l and 2, is a quill extending from the swinging frame G1 G2, and serves as a housing for I the shaft for the cutting or burnishing wheel H. As this wheel H is hung upon the swinging frame G1 G2, which, in its turn, is hung upon the verticallysliding frame K, it is evident that it is free to move up and down, and also that its shaft may be inclined at any angle. G4 is a link rigidly attached to the swinging frame G1 G2,

.and connected, by a pin, G5, to the slotted arm N, so that the pin G5 becomes a second center, about which the swing frame Gl G2 swings as the slidingframe K is moved up and down. I

the wheel H by means of the disk E and pin E, Fig. l. The pin E presses through a slot in the disk, so that, though the relative positions of the two disks may change, one will always drive the other. k1 is a weighted lever, having a fulcrum at It, and serves to operate the sliding frame K, and through it and the swinging frame G1 G2 the cutting-wheel H. 7a4 is a footlever which, operating through the link 7a3, moves the lever k1. The weight k2 on the lever k1 serves to throw up the cutting-wheel H when not in use. The cutting action of the wheel H is limited and regulated by the moving guidel Z1 l2, Fig. 3. This guide has a rack on its under side which engages with the pinion L, Fig. 3. The slide K, the motion of which governs the cutting action of the wheel H, is provided with a pin, K3, which rests, when the machine is in action, upon the sliding guide l l1 l2, and, as the guide l l1 l2 is moved by the action of the heel-piece M, it will limit the motion of the cutter a-nd cause it to cut the heel into the proper shape, the exact shape being govern ed by the guide lll l2. The angle of the edge of the heel is automat ically regulated by themotion of the arm G1 G? as the shoe revolves.

I claim as my inventionl. The combination of the cutter H, the arm G1 G2, and the sliding frame K, substantially as described, and for the purpose set forth.

2. In a heel-trimming machine, the sliding guide Z Z1 l2, operating, in combina-tion with the cutter H, substantially as described, and for the purpose set forth.
