Abstract

A multi-purpose hand tool having novel structure that allows it to partially function in the manner of a revolver. It has a multi-chamber revolver-like cylinder which revolves and holds various sizes of screw drivers, Phillips head drivers, Allen wrenches, sockets, screw starters, etc. The tool has a primary shaft whose rear end is connected to the drive shaft of a D.C. electric motor mounted in the rear body assembly. The drive shaft passes through an aligned bore hole in the front body assembly that is mounted immediately behind the revolver-like cylinder. The rear body assembly is mounted in a track formed along the top edge of the handle assembly so that the rear body assembly may be reciprocally moved rearward to disengage the primary shaft from one driver tool to the next driver tool that the user desires to place on the end of the primary shaft. The front body assembly has been designed so it may be used in conjunction with the revolver-like cylinder in a manual operation by removing the front body assembly and attaching a ratchet handle assembly to its rear end. Various auxiliary assemblies can be detachably mounted to the hand tool.

A multi-purpose hand tool comprising:

an elongated rear body assembly having a longitudinally extending axis, said rear body assembly having a front end, a rear end, a top surface and a bottom surface, a compartment is formed in said rear body assembly and a D. C. electric motor is mounted therein and it has at least one drive shaft extending from one of its ends;
an elongated primary shaft having a predetermined length and having a front end and a rear end;
means for connecting said driveshaft to the rear end of said primary shaft so that said primary shaft can be rotated;
a handle assembly having a rear body assembly mounting portion and a handle portion, said rear body assembly having means on its bottom surface that mates with means on the top surface of the rear body assembly portion of said handle assembly that allows said rear body assembly to be reciprocally slid along the top surface of said mounting portion which allows the front end of said primary shaft to be withdrawn rearwardly from said revolver-like cylinder;
a front body assembly having a front wall, a rear wall, a top wall, and a pair of laterally spaced side walls, a bore hole extending from said front wall to said rear wall and being of a diameter such that said primary shaft freely passes therethrough;
means for detachably securing said front body assembly to the front end of said rear body assembly;
a revolver-like cylinder having a longitudinally extending axis, said cylinder having a front face and rear face, said cylinder having a first set of recesses formed in its front face that align with apertures in said rear face, said first set of recesses having longitudinally extending axes that are parallel to each other, said first set of recesses having their axes on a first common radius, said first common radius being substantially equal to the lateral distance from the longitudinal axis of said primary shaft to the axis of said cylinder;
and
means for rotatably connecting said cylinder to the front wall of said front body assembly.
