BASOOM R. WELOH, OF WOLF CREEK, PENNSYLVANIA.

VEHICLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 258,514, dated May 23, 1882.

Application filed April 3, 1882. (No model.)

To all whom it may concern Be it known that I, BASCOM R. WELoH, a citizen of the United States, residing at Wolf Creek P. 0., in the county of Mercer and State of Pennsylvania, have invented new and useful Improvements in Brakes for Vehicles, of which the following is a specification.

This invention relates to that class of brakes for wagons or other vehicles in which a bail supported upon a bar that crosses the hounds is employed in connection with the brake mechanism.

The objects of my invention are to insure certainty and readiness of action on the part of the brake mechanism; to obviate unsteadiness of movement; to diminish friction, and to generally improve the said mechanism. These objects I attain by means of the construction and combination of devices illustrated in the annexed drawings, in which- Figure 1 represents a top or plan view of my invention in position on the reach and hounds of a vehicle;.Fig. 2, a perspective view of the brake mechanism detached from the vehicle; and Fig. 3, a sectional perspective view of part of the hounds and the crossbar supporting the brake-bail, to illustrate one of the eyebolts in which the bail rocks.

The letter A indicates the reach, and B the hounds, that are secured to the rear axle. O, as usual. A grooved cross-bar, D, is bolted at its ends to the hounds, and arocking-bail, E, is arranged within the groove of this bar, and retained therein by means of eyebolts F, the straight portion of the bail passing through the eyes of these bolts, which are employed for the purpose of bolting the grooved bar upon the hounds. A brake-bar, Gr, carrying suitable brake-shoes at its ends, is arranged below the hounds, the length of this bar being such that its ends project out at the outer sides of the hounds, as shown. The bent or crank-shaped ends of the bail connect with the brake-bar by means of eyebolts g, which pass through the brake, whereby the latter will be supported, and, while free to be moved backward or forward below the bounds, it will be incapable of any endwise shift.

H H indicate the draw-rods, which pass through the brake-bar, and are secured thereto by nuts fitted upon the rods and tightened up against opposite sides of the brake-rod. These draw-rods connect at their opposite ends with arms 6 upon a rock-bar, I, that is mounted upon the hounds and retained thereon by suitable boxes, eyes, or other appropriate bearings. The ends of the rock-bar extend beyond the outer sides of the hounds, and to an arm, 1', upon either one of said ends, is connected the brake-rod K, which will be connected in any suitable way with the brake-lever employed for operating the brake mechanism. By vibrating this lever in one direction to apply the brakes a partial axial rotation will be given to the rock-bar, which will in turn operate the draw-rods, and hence move the brake-bar toward it, so as to throw the brake-shoes upon the wheels, the bail turning in its grooved bearin g in the crossbar during this operation, thereby steadying the brake-bar and also guiding the same.

It will be seen that the connection of the bail with the brake-bar will prevent any endwise movement on the part of the brake-bar, and also any lateral .strain upon the drawrods, the parts moving easily and steadily, and at the same time there will be no strain upon the bail, it being arranged with relation to the wheels so that the brake-shoes carried by the brake-bar will bear upon the wheels at the proper moment.

Having thus described my invention, what I claim is 1. In a brake mechanism, the combination of the cross-bar D, swinging bail E, supported thereby and having downward-bent ends, the brake-bar suspended from the bent ends of the bail, the cranked rock-bar I, a draw-bar connecting the crank of the rockbar with the brake-bar, and a brake-rod for rocking the rock-bar, substantially as described.

2. The combination, in a brake for vehicles, of the grooved cross-bar D, secured to the hounds, with the rocking bail E, arranged within the groove of said bar, and retained therein by eyebolts securing the grooved bar to the hounds, the brake-bar G, carrying the brake-shoes and connected with the crankshaped ends of the hail, the draw-rods rigidly In testimony whereof I have hereunto set secured to the brake-bar, and also connected my hand in the presence of two subscribing to arms upon a rock-bar that has its bearings witnesses.

upon the hounds, and" the rod connected with BASCOM RAYN WELGH. an arm upon the rock-bar, and also connected \Vitnesses:

with the operating-lever, substantially as de- H. B. BOWSER,
