ABSTRACT:
A self-aligning swivel caster for use on carts and the like, the caster being equipped with a member for locking and releasing the caster with respect to swivel movement. The locking and releasing member, which can selectively be oriented in an operative or an inoperative position, is friction and gravity actuated. The structural relationship of the caster and the member is such that automatic camming and actuation of the member occurs as the caster is swiveled from an unlocked position into a locked position or from a locked position into an unlocked position. During actuation of the locking and releasing member, the caster makes direct contact with the member until the member finally drops into the proper position to either restrict or facilitate further swivel movement of the caster.
