Abstract
Abstract In a railway freight car brake system, the brake system is transferred from one side of the center sill to the other side by means of transverse brake levers which are fulcrumed in the center sill webs. The levers pass through respective openings in the center sill webs and the openings may be provided with center sill reinforcement. Conventional fastening means, such as simple pin connections, may be used to connect the levers to either the center sill webs and/or to the center sill reinforcement. With this arrangement extensive prior art bracketing is avoided, and the transverse levers may be shorter. As a result there is less danger of the lever bottoming out in the center sill openings when the brakes are applied.
