Abstract
Abstract A handknob mounted on a heel plate and splined to a pinion meshing with a rack is permitted to rotate in one direction by a ratchet mechanism to permit the heel plate to be moved forwardly along the rack, and the hand-knob and pinion are normally prevented from rotation in the opposite direction by the ratchet mechanism to prevent the heel plate from moving rearwardly along the rack. When the knob is manually lifted, the ratchet mechanism is disengaged to permit the heel plate to be moved rearwardly along the rack.
