WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 295,008, dated March 11, 1884.

Application filed December 15,1883. (No model.) I

To (LZZ whom, it may concern.-

Be it known that I, JAMES HOOKING, a citizen of the United States, residing at Denton, in the countyof Lancaster andState of Nebraska, have invented certain new and useful Improvements in Wagon-Brakes, of which the following is'a description,

Figure 1 is a vertical longitudinal section through the brake mechanism, and Fig. 2 is a plan view of the same.

My invention relates to that form of wagonbrake in which the brake-shoes are automatically applied to the wheels by the back thrust The object of my invention is to provide alight and strong construction of gearing for this purpose, which is easily applied, which permits the wagon to be lengthened or shortened, and which can be applied either automatically or by hand, and which will also operate when the wagon is in the act of turning, as well as when it is straight; and to these ends it consists in a peculiar construction and arrangement of parts, which I will now proceed to describe.

In the drawings,A is a sliding cuff or sleeve, which is arranged loosely upon the reduced end of the tongue, and is adapted to slide rectilinearly thereon. This cuff has aprojecting staple or shoulder, a, on its underside, against which bears the usual connection of the neck-yoke.

B is a rod connected to this cuff, and run ning along the top of the tongue, and kept in position thereon by staples c 0.

D is a boX-frame,which forms a part of rod B, and through which box-frame the doubletree D runs. From the box-frame D the rod B is extended backward as a flat bar, B, which at its rear end, carries a horizontal grooved wheel, F. G G are two other grooved wheels,

arranged one upon each side of the wheel F, and mounted upon plate H just above the horizontal pivot of the tongue.

H is an iron plate running between the hounds, to hold the wheels G.

I is an iron chain running around wheels F G G and between wheels K K K, and attached to the head-piece of extensionrod L. The grooved wheels Kare set in the bolster, and

5c the king-bolt passesthrough the middle one.

L L is the extension-rod,inade in two pieces, with perforated ends, connected by bolts, so as to be lengthened or shortened as the reach is lengthened or shortened. This extension-bar is'jointed tothe brakebars N N. The rod L is guided in its longitudinal movement by straps M. The brake-bars are jointed at S on bolts, which are carried on the ends of wooden tableQ, straps or keepers B being used to hold the bolts S steady.

l? is a spiral spring which connects one of the brake-cars to the wagon-frame, and serves to remove the brakes from the-wheel after they have been applied. 0 O are two iron straps to prevent levers N N from rising when the brakes are put on.

In the operation of the brake as thus described,when the team is stopped, the pull of I the neck-yoke on cuff A drives it back with rod B B and forces pulley F to the rear. 7c This draws the chain I and pulls the extension-bar L L forward, and by deflecting levers N applies the brakes. Then,when the strain of the neck-yoke is no longer 011 the cuff, spring P pulls the levers or brake-bars N away from the wheels X, draws back the chain I and extensionbar LL, and pushes the rod B and cuff A forward again. To keep fromapplying the brakes in backing, the section B of the bar has a slot in it, and to said bar is attached a dog, E, that may be forced by the foot of the driver down to engage with ratchet-teeth d in the bar below. To apply or remove the brakes at will, also, I make one of the brakebars N longer than the other, and attach to it a pull-rod, T, which connects with a handlever,V, having a locking-banV, that engages with a notched curved bar, V. This device permits the brakes to be applied by hand, and also may be used in theplace of the dog E to lock the brakes so that they cannot be applied.

NV is a link on top of lever V, to hold the lockof the chain and the location of the wheels G permit the brakes to be applied when the front wheels are standing at an angle or the wagon is going around a curve,and permit the tongue also to be raised or lowered without friction or strain. lhe extension-rod L L also permits the wagon-reach to be lengthened for hauling hay or lumber.

Having thus described niyinvention, what I l Wheels G G, and the. backlash-rod B B, carrying wheel F, adapted to bear against the chain, as and for the purpose described.

2. The combination of the sliding cuffA, rod B B, bearing wheel F, the wheels G G, chain 1, wheels K K K, extension-rod L L, brakelevers N N, and spring 1?, substantially as and for the purpose described.
