ADD-ON UNIDIRECTIONAL BRAKE

摘要

A unidirectional brake is provided for addition to a caster of conventional construction having a wheel mounted to an axle for rotation, which axle is mounted in a yoke. The add-on unidirectional brake includes a pair of mounting brackets adapted to be mounted to opposite sides of the caster by means cooperating with the axle. The legs of a U-shaped bail member are mounted to the mounting brackets by hooks at the ends of the legs, which hooks extend inwardly through holes in the mounting brackets. When the brackets are in place and the caster is in an upright position, the legs extend rearwardly from the mounting brackets and the bight rests in contact with the periphery of the caster wheel and the hooks on the ends of the legs of the U-shaped bail member cooperate with the yoke to form stop means to limit movement of the brackets during rearward rotation of the wheel. The unidirectional brake of the present invention has particular application to the front casters of a tow line conveyor truck.
