RAILWAY CAR BRAKE RIGGING FULCRUM LEVER MOUNTING

摘要

RAILWAY CAR BRAKE RIGGING FULCRUM LEVER MOUNTING The upper end of a railway car live brake lever between the axles of a car truck is pivotally connected to one end of a link that extends across the top of the adjacent axle and is pivotally connected to the lower end of a vertical fulcrum lever. The central portion of the fulcrum lever is provided with a circular opening, the wall of which is convex from side to side of the lever and forms an arc of a circle. A rigid supporting member for the fulcrum lever projects laterally from one side of the center sill of the car and has a hook at its outer end extending through the lever opening and curved away from the live lever. The hook forms an arc of a circle and has a circular cross section, the radius of the inside of the hook being substantially the same as the radius of said wall arc. The inside diameter of the lever opening is only slightly greater than the diameter of the hook in cross section, and the upper end of the fulcrum lever is formed for connection to a device for rocking that lever around the hook.
