Abstract: An apparatus for a quick release mechanism in a railcar hand brake. The hand brake has a housing having a front casing with an inside wall of a predetermined size and shape, and a back plate. An operating shaft is rotatably mounted in the housing. The operating shaft includes a first end and a second end. The operating shaft further includes a ratchet wheel rotatable with the operating shaft intermediate the first and second ends thereof, and a release shaft rotatably mounted in the housing. The apparatus comprises a projection of a predetermined size and shape disposed substantially perpendicular to the ratchet wheel, and a flexible clamp of a predetermined size and shape mounted inside the housing.

Abstract: A quick release mechanism for a railcar hand brake comprises a release shaft having a first end and a second end. The first end includes a cavity of a predetermined size and shape. A release lever has a hub journaled on the first end of the release shaft. A stop of a predetermined size and shape is disposed on the circumference of the hub of the release lever and engageable with the cavity of the release shaft to rotate such release shaft to cause free release of the brakes. A projection of a predetermined size and shape is disposed on the second end of the release shaft. An attachment of a predetermined size and shape is mounted to an inside wall of a housing of such hand brake. A tension member has a first end and a second end. The first end is secured to the projection, and the second end is secured to the attachment whereby the tension member will return the release shaft to the brake application position.
