ABSTRACT:
A split socket ratchet wrench is provided. The wrench has an elongate handle terminating at jaws at the head end of the wrench. The jaws receive a rotatable split socket and ratchet wheel rotatable therein. A manually actuable pawl has extending projections engageable with the ratchet teeth. A separate cable spool at the handle end of the wrench is fitted with a torsion spring. A cable or filament extends between the cable spool and the ratchet wheel. As the socket is rotated, it carries with it the cable which is spooled around a hub of the socket. When the wrench is disengaged from the nut, the pawl can be released and the cable spool will rewind returning the socket to the normal "open" position at which point a registry stop on the socket prevents the socket from rewinding past the open position. A separate locking device senses when the cable spool is completely payed out and prevents the mechanic from further turning the socket.
