l. H ER D. Car-Brakes.
Patented May 5,1874.
UNITED STATEs JAMES BERD, OF JACKSONVILLE, OREGON.
vIMPROVEMENT IN CAR-BRAKES.
Specification forming part of Letters Patent No. 150,417, dated May 5, 1874; application led April 18, 1874.
To all whom it may concern:
Be it known that I, J AMEs HERE, of Jacksonville, in the county of Jackson and State ot Oregon, have invented a new and Improved Mode of Applying Brakes to the Wheels of Railway and Street Gars; and I do hereby de- Clare that the following is a full and exact description thereof, reference being had to the accompanying diagrams, and the letters of reference marked thereon.
My invention relates to that class of carbrakes, which are operated by means ot' a friction-disk secured on a supplementary axle. about which the brake-chain is wound when fthe disk is brought into contact with a friction-disk secured to the car-axle; and consists in providing one end of the supplementary axle with a laterally-moving bearing, that the position of the friction-disk may be regulated by means of a rod attached to the movable end of the supplementary axle and the hand-lever.
Figure 1 represents an under view of the car, and Fig. 2 a side elevation of the same.
y tached to a horizontal shaft, B, and has a movable bearing at the pulley end O, and stationary bearing at the other end G. As soon as the friction-pulleys are thrown into gear by moving the lever E, the motion of the'carwheels, either going forward or backward,
tightening the brakes K K on the car-wheels.
The lever E extends to the top of the car, and is worked by the brakeman, by means of a cord, F, and two pulleys, one of which is on the lever, and the otheron the top of the car, as shown in Diagram No. 1. This cord F may be connected with all the brakes on the train, and can be operated from any part of the train.
This improvement can be applied to the ordinary brakes now in use.
When the brakes are to be put on,thc brakeman with a very slight exertion pulls the cord F attached to the lever E, which throws the friction-pulleys into gear, the motion of the car-wheels throws the brakes on, as above eX- plained, and the friction ceases. When the brakes are to be taken oftl the brakeman simply slackens the cord F, and the strain on the shaft B, by means of the chain, pulls the friction-pulleys out of gear.
What I claim as my invention is The combination, with the car-axles and wheels y z, of the grooved and centrally-ilanged friction-pulley A, the shaft B with frictionpulley A', and movable and stationary bearings O G, lever E, rod H, lever J, chains a b, pulley D, end brake-blocks KK, all constructed to operate substantially as set forth.
