Clamping wrench
Patent
·
OSTI ID:5878487
The wrench comprises two longitudinal members, a main member and a clamping member, which are hinged about a pivot pin in the head of the wrench. The head of each member is cut so that it essentially provides a semicircular wall. These walls, when the wrench is in the closed position, form a circular orifice in the head of the wrench. Through a wall of one of the semicircular cutouts projects a spring loaded ratchet pin, the projecting end of which is beveled so that the wrench will ratchet in one direction. A pin is provided to lock the wrench in closed position and a set screw is utilized to hold the locking pin tight. The wrench may be used as a conventional hand-held wrench but it is sufficiently strong to be used as an impact wrench which can be hit with a sledge hammer. One object of the invention is to solve the problem of tools being dropped down a borehole when a cable is being worked on in position above the hole. Another object of the invention is to provide a device for tightening portions of a cablehead or downhole instrument together without requiring leveragable elements which project beyond the surface of the cable itself.
