ABSTRACT:
A multi-purpose hand tool having novel structure which allows it to partially function in the manner of a revolver. It has a ten or twelve chamber cylinder which revolves and holds various sizes of screwdriver, Phillips head drivers, Allen wrenches, sockets, screw starters, etc. The tool has a primary shaft that is journaled within a tubular sleeve and the shaft has a handle mounted on its one end and a male socket head formed on its forward end. The drive shaft may be sequentially driven forward to engage one of the tool heads in one of the chambers of the cylinder with further forward motion causing the tool head to exit the front of the chamber where it can be used to tighten or loosen a fastener. The drive shaft can be operated by hand, hand ratchet, an electric drill with an adapter, or by a battery powered electric motor mounted in the handle housing. To change tool heads, it is merely necessary to withdraw the drive shaft thereby depositing the tool head in its cylinder chamber and rotating the cylinder to the chamber containing the next desired tool head. the operation of moving the drive shaft forwardly again will result in the next tool head being positioned on the forward end of the drive shaft. A hollow support handle may be used to store additional tool heads and adapters therefore. An auxiliary handle having flashlight structure can also be attached to the housing of the tool.
