A brake mechanism for activating the brake rigging of a railway car, the bra ke mechanism comprising a shaft having axial splines formed on one end thereof, a handle rotatably coupled to the shaft so that the handle is rotationally fixed to t he shaft in a first direction and rotates relative to the shaft in an opposite second direction. A first gear is connected to the railway car brake rigging, a second gear is in operative engagement with the shaft splines, and a clutch is operatively disposed between the first gear a nd the second gear, the clutch having a coupler for rotationally coupling the first gear and the second gear and at least one spring operatively disposed intermediate the first gear and the second gear for biasing the coupler into engagement with the second gear. The coupler is moveable between a first position in which the first gear is rotationally coupled to the second gear, and a second position in which the first gear rotates with respect to the second gear. |
