IMPROVEMENT IN WAGON-BRAKES.

Specification forming part of Letters Patent No. 142,579, dated September 9, 1873; application filed March 29, 1873.

To all whom it may concern:

Be it known that I, WM. F. OSBORN, of Burlington, in the county of Coffey and State of Kansas, have invented a new and valuable Improvement in Wagon-Brakes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is arepresentation of a plan "iew of my wagon-brake. Fig. 2 is a sectional view of the same.

This invention has relation to automatic brakes for wagons; and it consists in the construction and novel arrangement of the brakebars and front bolster, of the slotted sliding coupling pole or reach and the connectingbars, as hereinafter described. The object of the present invention is to provide a convenient arrangement of the parts of awagon-bed, whereby the brakes will be applied to both front and hind wheels simultaneously, when actuated by the moving forward of the carriage or wagon bodyover the front bolster.

1n the accompanying drawings, the letters A A indicate the brake-bars, one being arranged behind the fore wheels, and the other before the hind wheels. B indicates the rear bolster, and b the rear hounds. G designates the front bolster, provided with the anti-friction rollers a and the front hounds c. D represents the coupling pole or reach slotted at 01, near its front end, the coupling-bolt epassin g from the front bolster through this slot. The

rear brake is connected with the rear hounds by brackets h, and similar brackets k, attached to the front hounds on their under sides, suspend them from the front brake, which is connected by rods z with the reach. E designates connecting-rods extending from the front bolster to the rear brake. F is a lever, the lower end of which extends downward in front of the coupling-pole when it is desired to back the wagon. This lever is attached to the front bolster.

It is apparent that when the wagon is goin g down grade the body, which is secured to the rear bolster, will ride forward, the coupling-pin of the front bolster passing backward in the slot of the reach. 7 The front brake will be drawn forward in its bearings by the forward movement of the reach against the front wheels, while the rear brake will be pushed backward by the rods E against the rear wheels.

What I claim as new, and desireto secure by Letters Patent, is-

The combination of the bar A, connected to the reach by the rods 2, the bar A, connected to the bolster by the rods E, the reach I), and bolster O, the whole adapted to lock the fore wheels and the hind wheels at the same time,

substantially as set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

WVILLIAM FAIROHILD OSBORN.
