  • Patent number: 4873899
    Abstract: An adjustable ratchet wrench (10) for turning a shaft (12) having a key (14). The ratchet wrench (10) includes a socket element (22) received within the head (18) of the wrench. The socket element (22) has an inner diameter (24) in which a key receiving slot (27) is formed. The socket element (22) is operatively connected to the head (18) by a ratchet mechanism (28). The inner diameter (24) of the socket element (22) is effectively modified by positioning a crescent block (38) within the inner diameter (24) of the socket element (22). The crescent block may take the form of a jaw (39) or a bushing (52). The jaw may include one or two jaws which are shifted radially by an adjustment screw (45) relative to the socket element (22). The bushing (52) includes a retention mechanism (56, 57) for securing it within the inner diameter (24) of the socket element (22).
