ABSTRACT:
The device automatically adjusts the slack in the brake linkage of railway vehicle during the braking process and has two telescoping rod members one of which is connected with a brake motor and the other is connected to the brake linkage. A nut, nonrotateably mounted on the brake linkage rod member, is threaded upon a rotateable spindle shaft which is axially moveable a limited distance within the brake motor rod member and is connected to this rod member by a control clutch. When the control clutch is stressed by torque, the control clutch member will become disengaged from the brake motor rod member to permit a relative adjustment between the two rod members to overcome any slack. When slack is overcome, a rotary clutch between the threaded spindle and the brake motor rod member will be engaged so that braking force can be transmitted between the rod members. A pretensioned spring stresses the brake motor rod member in the direction opposed to the braking force but does not exert any force upon the clutch control member.
