2059633 9101853 PCTABS00003 An adjustable ratchet wrench has a housing (24) carried by a handle (20). The housing has a generally cylindrical chamber which carries a disc (42) which in turn supports three equidistantly spaced jaws (26). The mounting disc (42) is connected to the handle (20) by a ratchet assembly (30) whose setting determines the direction in which the tool may be used to turn the nut or other workpiece. The housing (24) also carries a cam disc (74) that engages the jaws (26) and opens and closes them depending upon the direction in which it is rotated. A second ratchet mechanism (32) determines the direction in which the cam disc (74) may be rotated with respect to the mounting disc (42) so as to open and close the jaws (26).
