ABSTRACT:
A brake cylinder comprises a brake actuator device having a fluid operable piston and a coaxial adjoining hand brake operable device for axial actuation of a coaxial tubular push rod, there being a slack adjuster for selectively adjusting the retraction of the push rod. An actuating rod is connected to the piston and the actuating rod is selectively connected and disconnected from the internal periphery of the push rod by locking rollers selectively cooperating with a wedge shaped annulus disposed between the actuator rod and the inner periphery of the push rod. Slack adjustment is permitted by axial travel of the push rod beyond free travel limits as permitted by a friction sleeve connection between the outer periphery of the push rod and the brake cylinder housing. In a modification, the locking device is provided for a fluid spread brake cylinder that is adapted by levers to be connected to a conventional freight brake rigging to be used, for example, for hand brake applications.
