摘要： An adjustable die assembly having a ring structure with a clear central aperture for locating the ring structure along an axial length of a rod to have threads repaired or cut, and having a plurality of thread cutting chaser inserts connected to tool blocks which are slidable radially on said ring, each tool block connected to a threaded adjustment shaft, threaded into said ring for adjusting the radial position of each chaser insert. Alternatively, each threaded adjustment rod can be provided with a pinion gear, and a rim gear can be in mesh with each pinion gear, and a gear device can be provided for turning the rim gear to simultaneously adjust all chasers radially.

摘要： A tool for rotating a rod is provided which is formed of three members. A first member is formed as a sleeve and has an internal opening size to receive the rod. This sleeve has a tapered, portion which is placed over the rod. A second member, which may also be in the form of a sleeve slips onto the first sleeve and engages against the tapered portion. A third member sleeve is axially fixed to one of the first and second members and engages against the other of the members. A mechanical arrangement is provided to selectively urge the third sleeve apart from the other members against which it engages in order to move the second member and the first member relative to one another along the tapered surfaces to collapse the end of the first member engaging the rod to increase the gripping force of the first member with the rod. The first member has a shaped contour for receiving a torque applying device, such as a wrench, so that the first member can be rotated, thus rotating the rod.

摘要： A wrench socket that has a driven end for receiving a driving wrench in an internal or female drive opening, a driving end for engaging a threaded fastener to transmit a driving torque to the fastener and an intermediate external or male drive surface area which can be engaged by a second driving wrench. A removable retaining member is provided to assure that the second wrench is held on the socket, and a series of sockets may be provided which have various sized driving ends, but all have identical sized female drive openings and identical sized male drive surface areas so that only a single sized first wrench or a single sized second wrench need to used to drive a range of sizes of threaded fasteners. The driving end can be in any form, such as a castellated opening, a female hex-shaped opening or a male hex-shaped projection.
