ABSTRACT:
An improved cone brake is disclosed having a lever which selectively moves a brake shoe into engagement with a brake drum to prevent rotation of a shaft. Cam faces on the lever and brake are configured to ensure that the brake shoe is guided smoothly and accurately into engagement with the brake drum. The disclosed brake shoe cam face may be used with levers moving in either direction of rotation about an axis of rotation of the shaft. This increases the versatility of the brake shoe. In another feature, a casing for the brake includes a slot which receives an anti-rotation key from the brake shoe. The brake shoe and lever are mounted on a portion of the brake drum to reduce the axial length of the brake. The overall construction is relatively simple and ensures that the cone brake is actuated and guided properly and smoothly to stop rotation of the shaft.
