An apparatus for quick release mechanism in a railcar hand brake (10). The hand brake has a housing (11) having a front casing (14) with an inside wall (12), and a back plate (13). An operating shaft (20) is rotatably mounted in the housing. The operating shaft includes a first end (21) and a second end (22). The operating shaft (20) further includes a ratchet wheel (23) rotatable with the operating shaft intermediate the first and second ends thereof, and a release shaft (40) rotatably mounted in the housing. The apparatus comprises a projection (24) disposed substantially perpendicular to the ratchet wheel (23), and a flexible clamp (30) mounted inside the housing (11). A member (41) is disposed substantially perpendicular to, and about the circumference of the release shaft (40), having a first element (42) disposed on the member wherein the first element interposes with the flexible clamp (30) when the release shaft (40) is rotated to achieve and maintain full brake release, and a second element (43) disposed on the member (41) and engageable with the projection (24) when the operating shaft (40) is rotated to disengage the first element (42) from the flexible clamp (30) to allow for brake application. |
