Abstract
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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
380 words
A multi-purpose hand tool comprising: an elongated primary tubular sleeve having a predetermined length, said tubular sleeve having a front end and a rear end; an elongated primary shaft having a longitudinally extending axis and being of a predetermined length that is greater than the length of said tubular sleeve, said primary shaft having a front end and a rear end; means for supporting said shaft within said primary tubular sleeve so that the primary shaft may rotate and travel axially whenever so desired; a support member having a top end and a bottom end, the top end of said support member being attached to the forward end of said primary tubular sleeve with said support member extending laterally therefrom; a cylinder having a longitudinally extending axis, said cylinder having a front face and a rear face; means for rotatably connecting said cylinder to said support member about said cylinder's longitudinal axis intermediate the top and bottom end of said support member, said cylinder's axis being parallel to the axis of said primary tubular sleeve; said cylinder having a plurality of recesses formed in its front face that align with apertures in said rear face, said recesses having longitudinally extending axes that are parallel to each other, said recesses having their axes on a common radius, said radius being substantially equal to the lateral distance from the longitudinal axis of said primary shaft to the axis of said cylinder; means for detachably securing a female socket having a tool head in each recess of said cylinder; and means for positively positioning the axes of the apertures in the rear face of said cylinder in alignment with the longitudinal axis of said primary shaft when said cylinder is rotated comprising a roller having an axis substantially perpendicular to the axis of said cylinder, means for rotatably mounting said roller to said support member and adjacent the bottom end of said support member and adjacent the rear face of said cylinder so that said roller travels along the rear face of said cylinder as it is rotated about its axis, a portion of the circumference of said roller being captured sequentially in said respective apertures on the rear surface of said cylinder to positively align a desired female socket with primary shaft.
Claim 2
Dependent Claim
