JAMES O CONNOR, OF JACKSON, MISSOURI.

BRAKE-SHOE.

SPECIFICATION forming part of Letters Patent No. 284,052, dated August 28, 1883.

Application filed April 19, 1883. (No model.)

To ctZ whom it may concern.-

Be it known that I, JAMEs O CONNOR, a citizen of the United States of America, residing at Jackson, in the county of Cape Girardeau and State of Missouri, have invented certain new and useful Improvements in Brake-Shoes i'or Vagons and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The object of this invention is to secure an adjustable wagon -brake shoe, whereby the brake-lock may be removed when worn out, and which will securely hold the same in place; and it consists in the construction and arrangement of the parts, as will be hereinafter more fully set forth, and pointed out in the claim.

In the annexed drawings, which illustrate my invention, Figure 1 is a perspective view showing the same applied to the brake-bar of the wagon. Fig. 2 is a plan view. Fig. 3 is a detailed perspective view of one of the side arms or wings detached.

A represents the brake-bar of a wagon, the front edge of which is cut away on a slant, as shown. To this brake-bar,opposite the wheel, are pivoted two wings or clamping-jaws, B B, which have upper and lower projecting arms, a, which embrace the brake-beam,and which are united to the same by a vertical bolt which passes through suitable perforations in the aforesaid wings and the brake-bar. By means of these bolts the jaws which hold the block in place are allowed a pivotal movement. These jaws are preferably provided on their inner surfaces, where they come in contact with the brace-blocks, with serrations, and the proj ecting portions of said jaws are beveled, so as to correspond with the cut-away portion of the brake-beam on the inner edge, and with the periphery of the wheel on the outer edge. The upper and lower portions of the embracing-arms are connected by a vertical wall; 0, which forms the inner portion of the jaws. These jaws are perforated at a suitable point for the reception of a bolt, E, by means of which the jaws can be drawn together, so as to hold the brake-blocks securely in place. To attach a brake-block within these jaws, all that is necessary is to cut in said brace-blocks a transverse slot of sufficient size to pass over the bolt E, after which the bolt can be tightened and the jaws firmly compressed upon the same.

It is evident that the transverse slot in the brakeblock will prevent the same from being displaced vertically, while the serrated edges will prevent a lateral displacement. The walls 0 of the jaws, at their exterior portion, are provided with raised projections, which bring the nut at the end of the bolt'E beyond the upper and lower wings, so as to afi'ord easy access thereto with a wrench.

By the device hereinbefore described Iprovide the means whereby a brake-block may be readily attached to a brake-bar and re moved therefrom when worn out.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- As a means for attaching a brake block or shoe to the brake-bar, the pivoted jaws embracing the upper and lower edges of the brake-bar, and provided with a central wall,

with vertical serrations and inclined edges and perforations for the reception of a transverse bolt adapted to be used in connection with the brake block or shoe, having a transverse slot which embraces said bolt, substantially as shown, whereby vertical and lateral displacement of the block is prevented.

In testimony whereof I aflix my signature in presence of two witnesses.

JAMES OGONNOR.
