SPECIFICATION forming part of Letters Patent No. 425,304, dated April 8, 1890.

Application filed'l'imnary 30, 1890. Serial No. 338,602. (No model.)

To all whom, it may concern.-

Be it known that 1, JAMES A. ORIswELL, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in RailwayBrake-Shoes; and I do 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 of reference marked thereomwhich form a part of this specification.

Figure 1 of the drawings is a representation of the invention and is a perspective view. Fig. 2 is a vertical section, and Fig. 3 is a ma view.

This invention has relation to certain improvements in railwaybrake-shoes and it consists of the novel combination and construction of parts, as will appear from the following description and accompanying illustration.

In the drawings, A is the shoe proper,which is of the usual construction in its general outline, being concave-convex, and having upon its convex or outer surface, at the lower end, an eye stud or knee a; but at the upper end of this shoe,upon the same surface, is provided a hook I), curved or pointed downward and outward, the purpose of which will appear farther on.

B is the box, conforming in its general contour to the shoe A, and having its inner concave surface or face presented to the convexity of the shoe, and in its lower end a slot 0, which receives the eye stud or knee (1, of the shoe, and in its upper end a slot (I, which receives and permits the engagement of the hook I) of the shoe therewith. The slot (Z, which sufficiently indents the box to prevent lateral displacement of the engaging hook, terminates upon the outer side of the box into a recess d, whose sides flare downward, the bottom (1 of which recess forms a fulcrum for said hook. The outer or upper surface of one of the end pieces of the box B is also recessed, as at its side walls, flaring outward, said recess forming an extension of the recess (1' to permit the same to remain intact at that point when the pattern is removed from the sand,

while by means of the recess (1 the hook I) is allowed to have slight lateral play. .The slotc terminates upon the inner side of the box 13 into a recess 0', whose sides flare upward or reversely to the flare of the sides of the recess d, which permits the core of sand to occupy a position in the upper part of the flask of the mold as the cope is removed. The inner face orsurface of the upper part of the box I3 is formed with a slight central longitudinal ridge or bearing 6, which rests or bears upon the shoe A, thus permitting the box to rock thereon and conform to the tread of the oar-wheel. The box B is provided with the usual socket f to receive its carrying-bar, and with a central hole or aperture for the bolt securing it to said bar.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The brake-shoe consisting .of the shoe proper, having an eye stud or knee and a hook, and a box having upon its inner surface or face a central longitudinal ridge or hearing, and means for fastening said knee or stud to said box, substantially as specified.

2. The brake-shoe consisting of the shoe proper, having a hook and an eye-stud, and the box having end slots, one terminating into a recess whose bottom serves as a fulcrum for said hook, said box having upon its inner surface a central longitudinal ridge or bearing, and means for connecting the lower ends of said shoe and box together, substantially as set forth.

3. The brakeshoe consisting of the shoe proper, provided with the hook at one end, and the box provided upon its inner surface with a central longitudinal ridge or bearing and at its ends slots, one terminating into a recess upon the outer side of the shoe, and the other slot terminating into a recess upon the inner surface of the box, and means'for connecting the lower ends of said box and shoe together, substantially as set forth.

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

JAMES A. CRISINELL.
