ABSTRACT:
An improved tool particularly suited for removing nuts and the like from a stud or similar retaining member. The tool includes a split housing having channels therein extending along perpendicular axes, and at least one cam follower pivotally mounted within the housing. A shaft is slidably positioned in one channel for linear movement along an axis. The shaft is threaded at one end and extends through the housing and has a rotating member coupled thereto which bears against the exterior of the housing. On the opposite end of the shaft a camming surface engages one end of the cam follower to cause movement of the follower in response to movement of the shaft. A cutting element is slidably positioned within a channel in the housing for linear movement along an axis perpendicular to the axis of the shaft. The cutting element is coupled to engage the opposite end of the cam follower for movement in response to movement of the follower. When the rotating member is turned, the shaft is linearly moved within the housing to cause pivotal movement of the follower and linear movement of the cutting element. By placing the cutting element adjacent the side of a nut and turning the rotating member, the cutting element may be forced to sever the nut for removal. Thereafter a socket, having extended inner surfaces, may be used to turn the nut for final removal.
