UNITED STATES PATENT OFFICE.,

IMPROVEMENT IN SHOE-EDGE-TRIMMING MACHINES.
Specification forming part of Letters Patent No. 167,816, dated September 21, 1875; application filed July 10, 1875. Y
To all whom it may concern:
Be' it known thatwe, CHARLES J. ADDY and ESSEX S. ABBOTT, both of Boston, county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in a Sole-Edge-Trimming Machine, of which the following is a specification:
The nature of our invention consists in combining, with a suitable step or cutting block and guide, a vibrating cutter, said cutter vibrating nearly in a plane at right angles to the fece ofthe step or cutting-block.
The exact nature of our invention may be best understood by reference to the accompanying drawings and specification. v
Figure l is a plan'of our invention. Fig. 2 is a front elevation `of the same. Fig. 3 is a vertical section of the same. Fig. 4 shows the guide and cutting-block in. plan.
Let A represent the frame or table, to which the working parts are attached. B is the driving-pulley, which has attached to the end of its shaft a crank-pin, O, Figs. l and 3. D 'is a vibrating arm, pivoted on the trunnions D', asl shown. at Figs. 1 and 2. This arm D is made to vibrateby the crank-pin O, which acts in an oblong hole in the arm, as shown at Fig. 3. E is a cutting-knife, attached to the vibrating arm D. This knife E cuts against the step or cutting-block F, Figs. 3 and 4.. The cutting-block or step F is made stationary, and has a thin edge, which runs in the rand, H7 Figs. 1, 3, and 4, is a movable guide, made forked shape, as shown in Fig. 4, and having a band or plate of metal, K, at its front end. This plate K is made very smooth, and serves to form a guard to rest against the upper or vamp of the boot or shoe, and as this is m'ovable, by means of the bent lever L, the rod N, and the foot-lever '0, (see Fig. 3,) it can be adjusted by the action of the foot on the lever L, so that it may be brought into any desired position in relation to the step or cutting-block F. Thus the edge of the sole may be trimmed close to the vamp, or at any desired projection from it.
To use our machine we proceed as follows: The machine is started, and the guide K set at the desired point; then the boot or shoe isheld so-that the step or cutting-block F is in the rand, and the boot or shoe is moved along so as to present all -parts of the sole-edge to the action of the knife E. As the knife E CHARLES J. ADDY. ESSEX S. ABBOTT.
