Abstract (en)
In combination with a hand brake system for a railway vehicle including first and second spaced-apart brake beams. First and second transfer levers are pivotally connected at a point intermediate the ends thereof to a respective one of the first and second brake beams. First and second force-transmitting members are interconnected between corresponding arms of the first and second transfer levers. Such first force-transmitting member including a brake actuator device operable in response to the supply of fluid pressure thereto for increasing the length of the first force-transmitting member, to accordingly increase the spaced-apart distance between the first and second brake beams. A transfer link is connected to the first transfer lever so as to be arcuately movable therewith in a plane parallel to the plane of rotation of the first transfer lever. The improvement comprises a thrust block (110) disposed on the first brake beam. The thrust block (110) having a pin member (104) disposed therein. There is an actuating lever (100) having a pivotal connection at a location intermediate the ends thereof with the transfer link closely adjacent one end of the actuating lever (100) there is an arcuate portion (106') rotateably engageable with the pin member (104) and being adapted to receive a hand brake force. <IMAGE>
