Abstract
In combination with a railway car hand brake, there is an apparatus for sensing the hand brake release comprising a housing and a mounting mechanism for attaching the housing to a cover of such hand brake. An actuating mechanism is disposed in the housing. A sleeve member is disposed on the actuating mechanism and includes a flange. A flexible connecting mechanism engages the sleeve member and a winding gear portion of the hand brake. A sensing mechanism is disposed in the housing and aligned with the actuating mechanism. A securement mechanism is disposed on the sensing mechanism and mounted on the cover of the hand brake. A compression member is disposed in the housing and engages the flange of the sleeve member, whereby an electrical or magnetic signal will be received from the actuating mechanism by the sensing mechanism.
