ALBION K. WASHBURN, OF EAST'BRIDGEWATER, MASSACHUSETTS.

HEEL-BREASTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 237,646, dated February 8, 1881. Application filed December 23, 1880. (N model.)

To all whom it may concern:

Be it known that I, ALBION K. WASHBURN, of East Bridgewater, in the county of Plymouth and State of Massachusetts, have invented a new and useful Machine for Breasting Heels of Boots and Shoes, of which the following is a specification.

My invention relates to that class of machines which are provided with adjustable the upper part of the machine.

Let A B represent the frame-work of the machine.

D is the shoe-holding part of the jack, being hung on a pivot at D, and is provided with an adjusting-screw, d, so that it can be adjusted to any required angle, thus enabling the operator to cut the heel at any inclination to the sole that he may require.

D is a block, to which the upper part, D, of thejackis pivoted, as shown in Figs. 1 and 3.

D is a rod extending from the jack to the swiveling boss E, Figs. and 2, the rod D being held in the block E by means of setscrews 0 e, so that the jack may be adjusted vertically to any desired height. The block E swivels on a pivot, E and is fastened, by the said pivot E to the stationary boss E, which is firmly affixed to the frameA B. (See Figs. 1 and 2.) By this method of attaching the jack-rod D to the frame I am enabled to swing the jack away from the machine in a plane parallel to the said machine, so that the boot or shoe may be easily put onto or taken from the jack.

H, Figs. 1 and 3, is a guide for the back of the heel of the boot or shoe, and is adjustable and held in place by a screw, h, which passes through a slot in theshank H of. the gage H, and fastens it to the projection H The projection H being fastened to the frame by an upright sliding piece, H which is adjustable vertically by means of a slot and a screw, H the screw H serves to hold the piece H to the frame A B.

L is a slide working in a frame, B, as shown in Figs. 1 and 3. This slide is drawn up bya tension spiral spring on the back of the machine, the spiral spring not being shown except at its upper end, S, Fig. 1. The slide L is drawn down against the tensivc action of the spiral spring S by means of the rod M and the foot-lever M, the foot-lever being pivoted at m, as shown in Fig. 1.

L is a projection from the slide L, and carries the cutting-knifeL and the safety-sole gage L, the knife and the gage being attached to the part L by means of screws N N, (see Figs. 1 and 3,) and are adjusted vertically by the screws T T. '(See Figs. 1 and 3.) This safety-gage L is to be so adjusted in relation to the knife L that it will come in contact with the surface of the sole at the time that the edge of the knife L? has completed its work of breasting the heel, and thus prevents the knife from doing any injury to the sole.

To use this device the operator places the boot or shoe on the jack D, with the back part of the heel against the gage H, and, holding it firmly in this position, presses down the footlever M, which action draws down the slide L and causes the knife L to out or breast the heel. Upon the operator removing his foot from the lever M the slide L and its parts are returned, by the action of the spring S, to their resting position, out of the way of the boot or shoe on the jack.

I claim as my invention 1. In a heel-breasting machine, the combination of the adjustable jack D l) and its rod D with the swiveling block E, substantially as described, and for the purpose set forth.

2. The combination of the gage H and its adjustable shank H with the adjustable projection H H whereby adjustment can be made in a lateral and vertical direction, substantial] y as described, and for the purpose set forth.

ALBION K. WASH BURN.
