WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 410,631, dated September 10, 1889.

Application fil d May 6, 1889. Serial No. 309,770. (No model.)

To all whom, it may concern.-

Be it known that 1, WILLIAM W. ATTE- BERRY, a citizen of the United States, residing at Chesterfield, in the county of Macoupin and State of Illinois, have invented a new and useful iVagon-Brake, of which the following is a specification.

This invention relates to wagon-brakes; and it has for its object to construct a device of this class which shall possess superior advantages in point of simplicity, durability, and efficiency.

lVith these ends in view the invention consists in the improved construction and arrangement of parts which will be hereinafter fully described, and particularly pointed out in the claims In the drawings hereto annexed, Figure 1 is a top view of a vehicle running-gear provided with my improi'ed brake attachment, parts of the same having been broken away for the purpose of showing the construction more clearly. Fig. 2 is a bottom view. Fig. 3 is a longitudinal vertical sectional view. Fig. 4 is a transverse section.

The same letters refer to the same parts in all the figures.

A and B designate the front and rear axles, which are mounted in the usual manner upon wheels 0.

D designates the reach or coupling-pole, which is adjustable longitudinally by means of a bolt E, passing through the said couplingpole and through a plate F, connecting the front ends of the rear hounds G G.

H is the king-bolt, which connects the front bolster pivot-ally with the front axle and the front end of the coupling-bolt. The rear end of the latter extends through a recess in the under side of the rear bolster.

The front hounds, between the front ends of which the tongue is to be mounted, are arranged in the usual manner between the front axle and sand-board, and the rear ends of said front hounds are connected in the usual manner by means of cross-bars I and J, arranged, respectively, above and below the reach.

K designates a plate, which is bolted or otherwise firmly secured upon the plate F and the front ends of the rear hounds G. Said plate is provided at each end with a downwardly-extending loop or bracket L, in which the brake-bar M is arranged to slide longitudinally, as shown. The said brake-bar is provided at each end with the brake-shoes N N, adapted to bear against the rear wheels of the vehicle. The brake-bar M is provided with downwardly-extending pins or studs 0 0, adapted to retain the said brake-bar in position in the brackets L and prevent it from being displaced laterally.

Secured centrally to the rear side of the brake-bar M is a block P, to which is attached a leaf-spring Q, the ends of which bear against the rear sides of the loops or brackets L L, thereby serving to force the said brake-bar normally in a forward direction.

Mounted pivotally upon the under side of the rear axle B are two levers R R, the outer ends of which are connected with the brakebar M by means of rods S S. The bolts T '1, upon which said levers are mounted, are c011- nected with the under sides of the rear hounds G by means of brace-rods U, whereby the said bolts are prevented from being displaced by the strain incident to the operation of the device.

V is a rod arranged to slide longitudinally in suitable bearings \V, attached to the reach or coupling-pole, and the rear end of said rod is provided with an upwardly-extending flange or bracket X, having a transverse slot Y, through which extends a plate Z, which is connected adjustably to the said rod D by means of screws or bolts to. The said plate Z is also provided with a collar 1'), encircling the sliding rod V, and serving to connect the said plate and rod more firmly together. The rear end of the plate Z is provided with a T-head c, the ends of which are connected by means of links (I d with the inner e nds of the levers R R.

J ournaled in suitable bearings upon the front side of the axle A is a rock-shaft e, the inner end of which has an arm or crank 00, which is connected by a chain g with the front end of the longitudinally-slidin g rod V.

The outer end of the rock-shaft c is pro vided with a lever f, by means of which the brake mechanism may be operated either by the hand or foot of the driver of the vehicle.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood.

It will be seen that by operating the rockshaft 6 by means of the lever f the sliding rod V will be moved in a forward direction, thereby, through the intermediate mechanism, moving the inner ends or arms of the levers R in a forward direction and forcing the outer ends or arms of said levers, together with the brake-bar M, which is connected to said outer arms, in a rearward direction, and thus forcing the brake-shoes at the ends of the brakebar M into contact with the rims of the hind wheels of the vehicle. As soon as the pressure' upon the brake-lever f is released, the

pressure of the leaf-spring Q, attached to the block E upon the rear side of the brake-bar M, serves to restore the latter to its normal position.

The construction of my improved wagonbrake is exceedingly simple, and it will be found certain and effective in its operation.

By connecting the crank upon the rock-' shaft journaled upon the front axle to the operating-rod V by means of a chain, as herein described, the front axle may turn in the usual manner without interfering with the successful operation of the brake mechanism. Having thus described my invention, I

claim- 1. In a Wagon-brake, the combination, with the running-gear, of a plate mounted upon.

the front ends of therear hounds and having downwardly-extending brackets or hangers, the brake-bar arranged to slide longitudinally in said brackets and having downwardly-extending guide-studs, a block secured centrally to the rear side of the brake-bar, a spring secured to the rear side of said block and bearing against the rear ends of said brackets or hangers and to force the brake-bar normally in a forward direction, levers pivoted to the under side of the rear axle, rods connecting the outer ends or arms of said levers with the ends of the brake-bar, a longitudinally-sliding rod mounted in bearings attached to the reach, links connecting the rear end of said sliding rod with the inner ends of the levers, a rock-shaft mounted in bearings attached to the front axle and having a crank at its inner end connected by the chain with the 1011- gitudinally-sliding rod, and an operating-lever at the outer end of said rock-shaft, substantially as and for the purpose set forth.

2. In a wagon-brake, the combination of the longitudinally-sliding brake-bar, a spring arranged to force the said brake-bar normally in a forward direction, levers pivoted to the under side of the rear axle, rods connecting the outer ends or arms of said levers With the longitudinally-sliding brake-bar, a longitudinally-sliding rod mounted in bearings attached to the reach of the running-gear and having at its rear end an upturned flange provided with the transverse slot, a plate extending through the said slot and having a ring encircling the longitudinally-sliding rod, bolts connecting the said plate adjustably with the lon gitudin ally-slidin g rod, links connecting the rear end of said adjustable plate with the inner ends or arms of the brake-operating levers, and a rock-shaft journaled in bearings attached to the front axle and having an operatingdever at its outer end and provided at its inner end with a crank connected by a chain with the longitudinallysliding rod, substantially as herein set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

WILLIAM IV. ATTEBERRY.
