JAMES MUTTON, OF FRISCO, UTAH TERRITORY.

CAR=BRAKE.

friPECIPICATICN forming part of Letters Patent No. 392,745, dated November 13, 1888.

Application filed July 16, 1888. Serial No. 280,105. (No model.)

To ctZZ whom, it may concern:

Be it known that I, JAMES hIUTTON, of Frisco, in the countyof Beaver and Territory of Utah, have invented a new and Improved Oar-Brake, of which the following is a full, clear, and exact description.

My invention relates to an improvement in car-brakes, and has for its object to provide a simple and effective means whereby, in the event of a collision, or when the train is brought to a stand, the brake will be auto matically applied to the wheels.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a partial bottom plan view of a car having my improvement applied. Fig. 2 is a longitudinal section on line 00 x of Fig. 1, and Fig. 3 is a partial transverse section on line y 3 of Fig. 1.

In carrying out the invention a transverse beam, 10, is attached to thelongitudinal floortimbers 11 of the car, which beam is adapted to project vertically downward at the rear of the draw-bar 12 and in front of the axle 18, near the latter. At the rear of the transverse beam 10, and in front of the axle, short bars 14 are secured to the floor-beams, one at each side of the car, as best shown in Fig. 3.

From the short transverse bars 14 a rectangular strap-yoke, 15, is loosely suspended extending below the bar and having secured to its under side a brakeshoe, 16, which shoe is adapted to engage the wheels, as best shown in Fig. 2. The brake-shoes 16 are normally held in contact with the wheels through the me dium of a'spring, 17, preferably elliptical,

which spring has a bearing respectively upon the inner face of the'under horizontal section of the yoke and against the under surface of the short transverse bars 14:, as best shown in Fig. 3.

Between the draw bar and the transverse beam 10, and parallel with the latter, a revoluble shaft, 18, is journaled provided with a central eye, 19, the said eye being connected with the draw-bar, which draw bar is adapted to be reciprocated by a chain or rope, 20, and the said shaft-eye is likewise connected by a similar chain or rope. 21, with a vertical ro tary brakeshaft, 22, held in hearings to pro ject above the sill and provided with theusual hand-wheel, as best shown in Fig. 2.

One end of a lever, 23, is attached to the upper end of the yoke 15 and fulcrumed upon the transverse beam 10, the other end of said lever being secured by a rope or chain to the rotary shaft 18, as best shown in Figs. 1 and 2.

It is evident that when the cars are coupled and drawn ahead, the draw-bar, when pulled out, will turn the shaft 18, and the latter acting upon the lever will raise the brake-shoes. As soon as the cars stop traveling the drawbar returns to its normal position and the springs 17 act and apply the brakes. In backing the brake is reversed by manipulating the brakeshaft 22.

A wear-plate, 24, is attached to the transverse beam 10, upon which the yoke and brake shoe slide. The spring encircling the drawbar may be dispensed with if desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination,with a sliding draw-bar and a rotary shaft attachedto the same, of a spri ng-actnated vertical]yreciprocating yoke, a brake'shoe attached to said yoke at its bottom, and a lever attached to said shaft and to the top of the yoke, substantially as shown and described, whereby the shoe is held upon the wheels of a car when at rest and disengaged when in motion, as set forth.

2. The combination, with a sliding drawbar, a rotary shaft attached to the same, the axle, and a transverse beam intervening the axle and shaft,of a springactuatedl verticallyreciprocating yoke, a brake-shoe attached to the under side of the yoke, a lever fulcrumed upon said beam and connected at one end with the upper end of the yoke, and aflexible connection between said lever and the roller of averticalbrakeshaft,substantially as shown and described.

3. The combination, with a sliding drawbar, a rotary shaft attached to the same, the

axle, a transverse beam intervening the axle and shaft, and a Vertical brake shaft; of a spring-actuated vertically-reciprocating yoke, 21 brake-shoe attached to the under side of the yoke, a lever fulcrumed upon said beam and united at one end to the upper face of the yoke,

and a flexible connection between the lever and rotary shaft and between the rotary shaft and the roller of the brakeshaft, snbstantiall y as shown and described.

JAMES MUTTON.
