NITED STATES CHARLES A. MILLENER, OF DESERONTO, ONTARIO, CANADA.

CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 275,930, dated April 17, 1883.

' Application filed February 21, 1883. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES A. MILLENER, of Deseronto, in the county of Hastings and Dominion of Canada, haveinvented anew and useful Improvement in Railroad-(Jar Brakes,

' of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation, partly in section, of my improvement shown as applied to a train of freight-cars. Fig. 2 is-a plan view of a car-truck to which my improvement has been applied. Fig. 3 is a front elevation of a car to which my improvement has been applied, the friction-bar being shown in section.

The object of this invention is to utilize the momentum of cars to apply the brakes.

A represents the wheels, B the axles, and O the bodies, of a train of cars.

D are the brake-bars, which are provided with shoes E, and are supported from the carbodies in the ordinary manner.

To the brake-bars D are attached the ends of rods or chains F, the other ends of which are attached to bars G. The bars Gr rest upon rollers H, placed upon and rigidly secured to the axles 13.

Above the rollers H are placed rollers I, which are pivoted to the lower ends of bars J, the upper ends of which are hinged to the carbodies or truck-frames in such positions that the rollers I, when lowered, will be above and a little in the rear of the rollers H, so that when the roller I is lowered its weight will press the bar G down upon the roller H, and the said bar will be drawn forward by the friction of the rollers H I, and the momentum of the car will be made to apply the brake; or the roller I may be hung in a frame perpendicularly over the caraxle, and by means of a lever attached to it and extending to one 1 side of the car be operated by the rope in a similar manner to that already described. By

this construction the friction of the rollers H I upon the bar G will tend to draw the roller I downward and forward, and cause the said roller to clamp the bar G against the roller H more firmly, and cause the brake to be pressed against the wheels with an increasing force.

K is a rope or chain which passes around pulleys L, pivoted to the journals of the rollers H, or to the bars J. The rope or chain K passes over guide-pulleys M, pivoted to the carbodies 0, and is attached at its rear end to a wheel and axle, N, placed in the caboose O, and at its forward end to a similar wheel and axle placed upon the engine,so that the brake can be applied and withdrawn by the engineer, or by a brakeman in the caboose. The wheel and axle N is provided with a ratchet-wheel and paw], P, for holding the rollers I in place when raised from the friction-bars G, and which is released to allow the rollers I to drop when the brake is to be applied.

Having thus described my invention,I claim as new and desire to secure by Letters Patent 1. A railroad-car brake constructed substantially as herein shown and described, andconsisting of the rollers attached to or formed of the car-axles, the rollers suspended from the car-bodies, and the friction-bars connected with the brake-bars, whereby the movement of the cars is made to apply the brakes, as set forth. 2. In a railroad-car brake, the combination, with the car-axle B, the car-body G, and the brake-bar D, of the rollers H I, the hinged bars J, the friction-bars Gr, and the chains F, substantially as herein shown and described, whereby the movement of the car is made to apply the brake, as set forth.

3. The combination of the bars G, connected with the brake-shoe bars, the rollers H, fast on axle, and the pressure-rolls I, arranged on pivoted arms, whereby a brake may be applied to the axle, as described.
