Abstract
A toothless ratchet and clutch mechanisms chararacterized by substantially continuous engagement of the rachet wheel, thus allowing the mechanism to operate even under very limited-space conditions. Also, a biasing mechanism for the stem of the socket driver of the rachet or clutch, which eliminates backlash, if the stem is undersized as compared to the socket cavity which receives the stem.
