Abstract: Tools are provided having a variety of uses, such as to support or raise an object, or exert force against a structure. In preferred methods, the tools are particularly suitable for use by rescue or emergency personnel to raise a vehicle, to open a door, or so forth.

Abstract: An apparatus for affixation to the steering wheel of a vehicle in an accident. The apparatus blocks the air bag in the event of air bag deployment during a rescue operation, thereby shielding rescue workers and vehicle occupants from injury.

Abstract: Apparatus is provided which couples to one jaw of a pair of jaws of an expandable jaw power tool to remotely apply and distribute expansion power of the pair of power jaws when the jaws are actuated. A sleeve or collar is fitted over one of the jaws of the pair of power jaws, the sleeve adapted to receive and support one end of a threaded shaft, the other end of which supports a power or pressure distributing member. The threaded shaft screw-couples into a tapped hole in the sleeve and impinges upon one side of the jaw over which the sleeve is fitted, locking the sleeve on to the jaw. Thrust or expansion power, normally applied between the two jaws upon expansion, is applied between one jaw and the remote power or pressure distributing member coupled to the locked sleeve.

Abstract: Each jaw of a pair of jaws of an expandable jaw power tool are individually modified so as to accept a shaft supported in one jaw while passing through the other jaw of the same pair. The shaft includes an adjustable power distributing member which makes the depth of the jaws adjustable and makes greater use of the power stroke of the jaws, distributes the power or pressure output of the jaws over a wider area and makes an improved power tool, adjustable at the point of application of power stroke.
