Abstract: A setting tool for screwing a threaded rod into a receiving material includes a work driver formed by a sleeve-like member. A retainer part is secured within one end of the sleeve-like member for holding the threaded rod while it is inserted. The end of the threaded rod located in the retainer part bears against a piston positioned within the sleeve-like member. A hydraulic medium holds the piston against the end of the threaded rod so that the rod is held in the work driver. After a threaded rod has been set, the rod can be removed from the retainer part by relieving the pressure of the hydraulic medium acting on the piston. The pressure is built-up as the threaded rod is screwed into the receiving material. The pressure is released by opening a valve connected to the space in the sleeve-like member containing the piston and hydraulic medium.

A means for releasing the abutting and locking means from the mounted stud is provided, upon which when the device is rotated, the device is unthreaded from the mounted stud. The abutting and locking means may be a cylinder with a chamfered end or other shape. The device may be rotatably driven by a conventional pneumatic source or by hand through a conventional socket or open-ended wrench.

Abstract: A chuck attachable to a drill powered by a reversible motor, is adapted for use in driving lag rods into wooden supports and has an axial bore extending therethrough which is partly threaded from one end to receive the machine-threaded end of a lag rod. A plug member is screwed into the threaded end of the bore of the chuck and has a formation enabling it to be so turned as to be seated at the inner end of the threads for engagement by the extremity of the machine threaded end of the lag rod. In order to so reduce the frictional engagement between the plug member and the extremity of the lag rod, the area of the engaged extremities is limited thus to ensure the release of the lag rod when the motor is reversed after the lag rod has been driven into the support to a desired extent.

Abstract: A tool mounting and demounting assembly for a drilling machine includes a cylindrical support mounted on a rotatable drill shaft into which a tool holder can be inserted. The tool holder has a groove which is engagable by a hook of a tongue mounted on the cylindrical support. A collar surrounding the cylindrical support can be biased to a position which forces the hooks inward so as to engage the groove for mounting a tool. A tool support holds the tool holder along an axis coaxial with that of the drill shaft so that the cylindrical support can be lowered onto the tool holder. The surface of the tool support engages and raises the collar for releasing the hooks from the groove so as to permit the demounting of a tool.
