JAMES R. BARRON, OF BARROINVALE, PENNSYLVANIA.

WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 615,128, dated November 29, 1898.

Application filed August 20, 1897. Serial No. 648,949. (No model.)

To all whom, it may cOnccPn:

Be it known that I, JAMES R. BARRON, residing at Barronvale, in the county of Somerset and State of Pennsylvania, have invented certain new and useful Improvements in Wagon-Brakes, of which the following is a specification.

My invention relates to improvements in wagon-brakes; and it has for its object to provide a simple construction and arrangement of brakes on wagons by which when they are applied to the wheels the wheels will have a tendency to further apply the brakes, so that the momentum of the wagon and load will be used in braking.

My invention consists of a rock-shaft suitably j ournaled to the running-gear at the rear part of the wagon and connected by a rod with the brake-lever at the front part of the wagon, by which it is rocked to apply the brakes. The rock shaft has arms either formed integral or otherwise secured to it, the free ends of which are bent to form right-angle extensions which project over the rear wheels, and they each have journaled thereon a roller which as the shaft is rocked is brought to bear upon the wheels. The rock-shaft is also provided with arms which project inwardly therefrom and engage the under side of the axle for the purpose of limiting the backward movement of the brake-shoes.

My invention also consists of certain other details of novel construction, which will be hereinafter more fully described, and specifically pointed out in the claims.

In order that my invention may be fully understood, I will proceed to describe the same with reference to the accompanying drawings, in which- Figure 1 is a view of a wagon having my brake applied thereto. Fig. 2 is a detail bottom plan view of the rear part of the runninggear, showing the rock-shaft journaled thereto. Fig. 3 is a detail perspective view of the rock-shaft and the brake-rollers applied thereto. Fig. 4c is also a detail perspective View and shows a modification in the form of rockshaft, and Fig. 5 is a detail perspective View of the plate in which the rock-shaft is journaled. Fig. 6 is a detail longitudinal sectional view.

In the said drawings, A represents the wagon-body, B the running-gear thereof, and G the rear axle, carrying the wheels 0, to which I preferably attach the brake-rollers. To the running-gear B and at the rear end thereof I secure the plates E, having the sleeve E at the end thereof, in which the rock-shaft F is journaled. The rock-shaft, Fig. 3, has the rods or arms G secured to the ends thereof, and their free ends are bent at right angles, so as to have the ends project over the wheels. The brake-rollers II are journaled in these extensions. To one of the rods G, I secure one end of the rod I, the other end of which is connected with the brake-lever I, which is pivoted at the front of the wagonbody and operated in connection with the usual rack-segment and pawl.

J J are short arms secured or formed with the arms G. The arms J J project inwardly from rock-shaft F and engage the under side of the axle for the purpose of limiting the backward movement of the brake-shoes.

As will be seen, the rock-shaft and rods are so arranged as to have the rollers when applied bear upon the rear wheels at a point to the rear of the axle, so that when they are applied the rotary movement of the rear wheels will tend to force the arms forwardly, and in this manner the momentum of the load and of the wagon will be utilized to apply the brakes.

In Fig. l I have shown a modification in the form of brake-arms employed. In this form the rods or arms G are formed integral with the rock-shaft and the rollers are jourat right angles, so as to throw the rollers over the rear wheels.

what I claim as new, and desire to secure by Letters Patent, is

1. In a wagon-brake, the combination of a rock-shaft journaled at the rear of the axle, brake-arms carried by said shaft, brake-shoes carried by the arms and adapted to engage the levers, and arms carried by the rock-shaft and adapted to engage the under side of the axle for the purpose of limiting the backward movement of the brake-shoes, substantially as set forth.

2. In a wagon-brake, the combination of straps carried by the running-gear at the rear naled on the ends of the arms, which are bent Having thus fully described my invention,
