DEFINITION

Classification: 248/288.51

Including mechanically actuated tension or locking member:

(under subclass 288.31) Ball and socket bracket comprising manually actuated means for maintaining a force on one component of the joint, usually for either taking up wear or for regulating the friction between a plurality of relatively movable components.

(1) Note. The force may be sufficiently great as to lock the components against movement or merely sufficient to cause resistance to motion.
