Abstract
A ratchet system includes a 'T' shaped stop-engaging member mounted in a plane perpendicular to a rotating spindle and parallel to a circular carrier member having stop members mounted on the periphrey and rotating with the spindle. The stem of the 'T' member is rotatable mounted in a housing surrounding the spindle and upon selective rotation, the ends of the 'T' member cross-bar engage the stop members to prevent rotation in a selected direction. The 'T' cross-bar transmits the engagement force directly to a recess in the inner wall of the housing. A hand-actuated knob assembly located outside the housing is connected to the 'T' member stem by a resilient bushing which provides a restoring force to return the 'T' member to a stop engagement position following defection by stop members traveling in a direction counter to that intended to be prohibited.
