IMPROVEMENT IN WAGON-BRAKE.

The Schedule-referred to in'these Letters Ratent and making part of the same.

To 'all whom it may concern: I 7

Be it known that I, J OHN T. BENNETT, of Lenora, in the courity of Fillmore, and State of Minnesota, have invented a new and improved Wagon-Brake and Look; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a longitudinal section of a wagon, provided with my improved braking and locking-attachments.

Figure 2 is a top .view of the same. Similar letters of reference indicate like parts. The object of this invention is to providea more simple and efi'ective arrangement of devices for braking wagons than those heretofore in use; and

The invention'consists in the particular combina tion and arrangement of the several parts, as will be hereinafter set forth.

In the drawingsa is a brake-bar, bearing the brake-shoes b b aflixed thereto .as shown.

This brake-bar slides to and fro in guideplates d, afiixed to the upper side of the longitudinal ports 0 c .of the houndsc f, c f: I

When moved forward, to apply the brake-shoes to the hind wheels, the baris actuated against the resistance of coiled splings e, coiled around rods g, projecting from the bar as shown. a

As the spring is thus compressed, these rods protrude through holes in the rear vertical parts of the guide-plates, as shown, which holes serve to guide the .rods and keep them in proper line.

The 4 braking-movement of the bar is obtained through the agency of the team in holding back and the mechanism conducing to this purpose; the-first part of whichv consists of connecting-rods, .h t, and cord m, arranged under the reach-pole and tongue, and connecting a sliding band, j, on the reach-pole k, with the neck-yoke l, as shown.

The cord 'm passes over a grooved pulley, 0, located in a mortise on the tongue near the end of the same.

Aplate, 01, arranged as shown, confines the moveas shown, and having their proximate ends slotted to work on a stud arising from the sliding band j.-

The other ends of these levers are connected by rods or links q q, with the bar a.

When the, wagon is descending a deolivity, the action of the team in holding back will draw, through I the agency of the cord, rods, and levers, as described, the brake-shoes against the hind wheels,and thus accomplish the braking of the same.

As'soon as .the team begins to draw, the springs actuate the bar back, thus relieving the wheels from the contact of the brake-shoes. I

When the wagon is to be backed, the lever-handle 'r is pushed forward. I

This lever-handle is aflixed to a shaft 3, having hooked arms, t t, of the requisite length to catch under the bar a, and the said arms are so arranged on the said shaft that when the levexs handle is pushed forward, the hooked parts of the arms will catch against the rear side of the bar, and prevent it from yielding to the action of the team,

The shaft s'has suitable hearings on the hounds as shown.

u is a bar, pivoted at u to the under side of the reach-pole k, andprovided with an iron-shod point 10. It is attached by a cord, 1;, to the arms t. Its oflice is to lock the wagon to rest the team when ascending long or steep hills.

Having thus described my invention, I-claim as new, and desire to secure by Letters Patent-
