SAMUEL B. LONG, OF SHELLSBURG, PENNSYLVANIA.

B RAKEf-SHOE.

SPECIFICATION forming part of Letters Patent No. 259,179, dated June 6, 1882.

Application filed April 17, 1882. (No model.)

To all whom it may concern 7 Be it known that I, SAMUEL B. LONG, of Shellsburg, in the county of Bedford and State of Pennsylvania, have invented certain new and useful Improvements in Brake-Shoes for Vehicles; and I do hereby declare. that the fol-' lowing is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective view of the brakeblock, with its shoe or rubber and clamp-bolts. Fig. 2 is a similar view of the block with the shoe removed, and Fig. 3 is a cross-section through the block and shoe.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to wagon-brakes; and it consists in an improved construction of the brake-block, to which the shoe-or rubber (which bears against the wheel in applying or setting the brake) is attached, having for its object to hold the shoe firmly at all times without slipping, while at the same time it can easily be removed, when required, for renewal.

In the accompanying drawings, A represents the brake-block, to the front side or face of which is secured by bolts B B an angleplate, 0, the face of which has a series of pro-. jecting teeth or sharp points, D D.

E E are clamp-bolts, which are inserted transversely through the brake-block parallel to each other, and nutted at their outer ends upon the back plate, F, of the brake-block.

G is the brake-shoe or rubber, which is held between the clamp-bolts E E, as clearly shown in the drawings. By tightening up the nuts of the latter the teeth or pointed projections D of face-plate G are forced into the wood of the rubber, thus holding it firmly in place and preventing its 'nioving either up or down, while the clamps, in conjunction with the teeth, prevent lateral or sidewise motion of the shoe upon the block. To detach or readjust the shoe, all that is necessary is to loosen the clampbolts, when the shoe will readily come oft without hammering. The shoe may be made simply from a flat piece of plank, of suitable length and thickness, shaped to lit between the clamps, and does not require to be out or shaped with tapering sides and face, as it is not wedged upon but clamped to the block A.

Iam aware that it is not new to construct detachable brake-shoes with clamps by which they are fastened upon the brake block or beam, or to make said block or beam with a notched or serrated face for the better attachment of the shoe; nor do I claim such construction, broadly; but
