Abstract:
A release holding mechanism for a railcar hand brake includes a release shaft rotatably mounted in the housing. A quick release handle is rigidly secured to an external end of the release shaft for rotation therewith and manually rotatable into a release position to initiate the quick release of the railcar brake application. A release lever cooperates with a driving mechanism of the hand brake to effect quick release of the railcar brake application. A release ratchet wheel is mounted for rotation with the driving mechanism. A release pawl operably engages the release ratchet wheel when the driving mechanism rotated for releasing the brake application. A gravity weighted member is disposed on and rigidly secured to the release lever for maintaining the release pawl, due to gravity, in a disengaged position relative to the release ratchet wheel when the driving mechanism is manually operable for effecting the brake application.
