Abstract

The present invention discloses a hand brake mechanism having a gravity based release hold mechanism with a visual indicator to prevent unwanted application of the railcar brakes and indicate such release hold condition. The release hold mechanism comprises a gravity based member pivotally linked to a release shaft preventing reverse rotation of the release shaft causing an unintended take-up of the chain. A detent retaining device disposed within the railcar hand brake housing further provides improve reliability of the operation. The gravity based member incorporates an indicator portion having a reflective coating to indicate such release hold position of the railcar hand brake.

Description

technical field [0001] The present invention mainly relates to a manual braking device for railway vehicles, in particular to a manual braking device with a quick release mechanism. Background technique [0002] Railroad vehicle manual braking devices are widely known to those skilled in the art. The device usually consists of a relatively large, rotatable handwheel mounted on and in the vertical plane of an axis which, through a gear train, rotates the chain drum to wind the chain, which is mounted on From the chain drum to the far end of the hand brake of a railway vehicle. When the handwheel rotates in a certain direction, the brake system is activated, and the rotation of the handwheel shaft in the opposite direction is stopped by a pawl engaged on the ratchet wheel of the handwheel shaft. [0003] These manual braking devices may also include a clutch that facilitates gradual release of the brakes. When the handwheel is turned clockwise (as viewed from the front of t...
