Abstract: A handle of a hand impact tool includes a pair of axial passages defined therein and a first row of axially spaced transverse openings defined in an outer periphery thereof and communicated with one of the axial passages. A second row of axially spaced transverse openings are defined in the outer periphery and communicates with the other axial passage. The axial passages are located in upper and lower end portions of the handle and are semi-circular or crescent in cross section. When hammering an object, the handle deforms not only in the axial direction but also in the radial direction due to provision of the transverse openings to effectively absorb shock resulting from hammering.

Abstract: A combination torque wrench and positioning assembly are used to provide the torque wrench function to both make up/break out pipe stands and to service drill string. While serving to make up/break out pipe stands, the wrench is positioned over and used in conjunction with a rotary or powered mouse-hole. When servicing drill string, the wrench is positioned over the drill bore rotary table. The combination of the present apparatus allows the rapid make up of pipe stands having individually torqued connections, eliminates the need for top drive torquing, and reduces the need for tongs and spin chains to handle drill pipe.

Abstract: A combined bottle opener and stopper comprises a metal plate with side edges bent downward and inwardly. Opening is performed with the use of a conventional pry off method. Opened bottles are closed with a rubber pad attached to the bottom of a recess on the inner face of the plate. The opener-stopper has three bent edges which have different heights with the difference corresponding to the pitch of the thread on a threaded bottle neck. For temporary closing the bottle, i.e., with beer or carbonated water, the device is screwed onto the threaded bottle neck as a nut until the rubber pad is tightly pressed to the upper face of the bottle to hermetically close the latter. For closing bottles with nonthreaded bottle necks, the device is moved onto the bottle neck by guiding the convergent bent edges over the neck in a direction transverse to the bottle's axis until the device is fixed tightly on the bottle due to convergence of the bent edges with the rubber pad, thereby to seal the bottle's opening.

Abstract: A driving device includes a hollow holding member having one portion that has a retaining section formed on an intermediate section of an inner periphery thereof.

Abstract: A ratchet wrench is designed to prevent overshooting and unintended switching of drive direction. The ratchet wrench has a wing member 44, which is biased by a spring 58 through a bushing pin 56, wherein an elastic member 66 formed of an elastic material, such as rubber, is incorporated into an axial internal space of the spring 58. Thereby, it is possible to strengthen a pressing force in a direction of holding engagement between a pawl of the wing member 44 and an internal gear 30 of an oscillating member 26. Thereby, in the case where a force is exerted on the wing member 44, in a direction tending to release the engagement between the pawl 46 of the wing member 44 and the internal gear 30 of the oscillating member 26, the spring 58 and of the elastic member 66 exert a reaction force, and the elastic member 66 functions as a stopper to prevent overshooting.
