IMPROVEMENT IN BRAKE-SHOES.

Specification forming part ofV Letters Patent No. 150,677, dated May 12, 1874; application filed y March 13, 1874.

To all whom it may concern Be it known that I, HENRY G. DEERING, of Hope Valley, Na pa county, State of California, have invented an Improvement in Securing Shoes to Brake-Blocks; and I do hereby declare the following description and accompanyin g drawings are sufcient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvement without further invention or experiment.

My invention relates to a simple and con venient device for securing shoes vto bra-kebloclrs, by which the shoe can be renewed with little trouble when it becomes worn out, and which secures the shoe so permanently that it cannot be lost or detached by accident. lt further consists of an improvement in securing the block to the brake-bar.

In ordery to more fully illustrate and explain my invention, reference is had to the accompanying drawing, forming a part of this speciiicat-ion, in which- Figure 1 is a perspective view of my invention. Fig. 2 is a section.

A is the brake-block. On the face ot' this block I provide, at each corner of .one end, a

post or block, b, which is as high as the thiclrness of the shoe to be used. C C are narrow plates or bars otl metal, having a portion, d, at one end equal in length to the height of the posts d, bent at right angles to the main portion of the bar. rIhe end of this bent portion d I then secure by a hinge or suitable joint to the corner ot' the block opposite the posts l, so that when the bars are closed down the end ot' the longer portion of the bar will rest upon the end of the posts, as represented at Figs. 1 and 2, and thus support the long portion of the bars G parallel with the face of the block. The extremity ot' thebars C which rests upon the posts b is slotred, as shown at e. A rod, f, passes through a hole in each corner of the block on which the posts b are formed, and the end which projects through the ends of the posts is bent over, as at g, so as to form a button or head. rEhe opposite end of the vrod is provided with screwthreads, and anut, h, is screwed down upon it on the backside of the block. The shoe I can be made of wood, leather, or other suitable material, and is of a proper thickness to be clamped down by the bars C when they are closed upon the posts b. A portion of each corner of one end of the shoe-piece I corresponding with the posts b is removed, so

that it will fit down upon the face of the block. Y

The clamps or bars G are then closed down, so as to clamp the opposite edges of the shoe. The button or head ot' each of the rods f is then passed through the slots e, and turned, so as to button upon the plate. The button is then drawn down upon the plate by the nut h, so as to irmly clamp and retain the shoe in place. The space between the bars C provides a bearing for the rim of the wheel when the brake is applied. l

lo replace an old shoe with a new one,- the buttons g are loosened and turned, so as to release the clamps. The block can then be removed and a new one inserted. The bars C should be made of steel, but any metal will answer. L is the hole. through the'block A through which the brake-bar passes, in order to support the block in position.

My improvement in securing the block on this bar consists in the employment of a set.- screw, m, which passes down through the back of the block, so that when it is turned down its end will press against the brake-bar inside of the hole L, and thus secure it by frictional contact.

By the above-described arrangement, I provide a cheap, simple, and convenient brake block, which can be used upon any class ot' land vehicles. f

Having thus described my invention, what I claim, and desire to secure by Letters Pat ent, is-

1. The block A, with its post b, and provided with the hinged clamps C, having slots e, in combination with the screw-rods j', with heads g and thumb-nut h, substantially as and for the purpose described.

2. The block A, having the hole L for the insertion of the brakebar, in combination with the screw m, substantially as and for the purpose described. y

In witness whereof I hereunto set my hand and seal.
