EMPTY-LOAD BRAKING APPARATUS

摘要

Empty-load braking apparatus for a railway car in which the cylinder of the fluid operable cylinder and piston means which actuates the brakes is slidably mounted and movement of the cylinder upon actuation of the brakes is opposed by a spring with a lightly loaded car. With a heavily loaded car, a pawl controlled by load responsive means on the car limits the movement of the cylinder so that a greater braking force is applied.
