UNITED STATES PATENT OFFICE.

RICHARD RABY, OF YORK, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO HENRY GETZ, OF SAME PLACE.

WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 444,318, dated January 6, 1891.

Application filed June 9, 1890. $en'al No. 354,783. (No model.)

To all whom, it may concern:

Be it known that I, RICHARD RABY, of York, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in VVagon-Brakes; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forminga partof this specification, and to the letters of reference marked thereon.

My invention relates to improvements in that class of wagon-brakes in which the brakeshoes are secured to arms pivoted beneath the body of the wagon in such manner as that when the brakes are 01f the said shoes are withdrawn under the Wagon-body practically out of view, so as to offer no obstruction in getting into or out of the wagon.

My special improvement consists in the particular construction of the brake-levers to which the shoes are connected and their mode of connection to the wagon-body, and in the general combination of parts which go to make up the braking appliance as a whole, as will be hereinafter described.

Referring to the accompanying drawings, Figure 1 represents a side view of a wagon provided with my improved brake appliance. Fig. 2 is a bottom plan view of the same, showing the brakes cit; and Fig. 3, a similar view showing the brakes on.

Similar letters of reference in the several figures indicate the same parts.

The letter A represents the wagon-body, B the front axle provided with wheels B; and C the rear axle provided with wheels C, as usual.

D D represent the brake-shoes; E E, the levers to which the brake-shoes are attached; F, links connecting the inner or shorter arms of the levers E to arms G G of a rock-shaft H, which is mounted in bearings on the bottom of the wagon and has an arm or crank I on its outer end, to which is connected a rod K, that is jointed at its other end to a lever or handle L, that is adapted to engage with a toothed locking-plate M in the usual manner.

Each of the levers E is formed of a single piece of Wrought-iron bent at E to form the pivoting portion, and having a long arm E turned down at its ends to receive and support the brake-shoe, and having the short arm E formed into an eye or loop E for the attachment of the link F. By thus constructing the levers E they are enabled to be made both light and strong. Especially is the bend ing of them at E to receive the pivoting screws or bolts S an important feature, as a larger and stronger bearing is thereby afforded than if the metal were perforated,while there is no sacrifice in strength.

\Vhen the brakes are not in use, they 00- cupy the position shown in Fig. 2, and, as will be seen, are entirely out of the way of and offer no obstructions to persons getting on or off the wagon; but when it becomes necessary to apply the brakes the lever L is pressed forward, which causes the rock-shaft II to be rocked and the levers E, through the links F, to be'turned, so that the brake-shoes carried by their outer ends will be forced against the tires of the rear wheels, as shown in Fig. 3.

I claim as my invention In a wagon-brake, the pivoted levers E, having the bent portions E, the long arms E with bent end to receive the shoes, and the short arms formed with the loops E in combination with the links F, the rock-shaft II, having the arms G G and the crank-arm I, the rod K, and the operating lever or handle L, substantially as described.

RICHARD BABY.
