THOMAS W. SOIITHARD, OF ROSES VALLEY, PENNSYLVANIA.

WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 299,866, dated June 3, 1884.

Application filed December 3, 1883. (No model.)

My invention relates to improvements in selfacting brakes, in which a sliding tongue enables the team to apply the brakes; and the objects of my improvements are, first, to provide a more substantial hound in which the tongue is free to slide or is made stationary at the will of the operator; second, to provide a suitable connection between the sliding tongue and rear brake, by which the objecti onable sliding circle is dispensed with; third, to provide a suitable connection between the rear and forward brakes, by which an equal pressure of both brakes is secured while going round a curve; and, fourth, to afford facilities for the proper adjustment of the brakes in respect to each other. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a top view of the entire wagon with brakes; Fig. 2, a detailed view of a vertical section of the entire wagon on the line 1 2, Fig. 1; and Fig. 3, an under view of a part of the wagon.

Similar letters refer to similar parts throughout the several views.

The facing P, made of two-inch band-iron extending back on the wooden braces h 7L and across at the rear end of the tongue T, with the straps S S S, (see Figs. 1 and 3,) make a more substantial hound, in which the tongue T may slide forward or back, or may be fastened by the pin a, applied as shown in Fig. 1, (or any other fastening,) when required to back the wagon, the rod 0, attached at one end to the tongue T, and atthe other end to the lever c, the upper end of said lever being connectedwith the wooden levers e e by the rod R, making the connection without a sliding circle, and securing the perfect action of the rear brake under all circumstances. The rod R extends beyond the rear brake, and is furnished with holes for the purpose of lengthening the wagon. A short rod or hook, Z, attached at one end to the rod 0* at the point designated by the letter L, Figs. 2 and 3, and at the other end to the bail b, which serves as a lever, and is connected with the brake-bar d by the rods f f, forms the connection and secures the action of the front brake.

One principal feature of the invention consists in the hook Z, corresponding in length with the distance from the joint 2' to the joint j on the rod 1', and being attached as shown above, operating as shown in Fig. 3, allowing a free action in turning, and at the same time securing an equal pressure of both brakes.

A wagon may be supplied with both or either of the brakes, at the option of the owner. If the front brake alone is used, it may be operated by a rod connecting the tongue T with the bail b, as shown by the dotted lines in Fig. 3.

I am aware that prior to my invention wagon-brakes have been made in which the team operates the brakes, by means of a sliding tongue and other connections. I therefore do not claim such a combination, broadly but What I do claim as my invention, and desire to secure by Letters Patent, is-

The combination, in a self-acting brake, of the rod 0', the lever c, the rod R, the hook Z, the bail I), and the rods f f, all substantially as described.

THOMAS IV. SOUTHARD.
