Portable vice

Claim 1

A portable vice comprising: a. A C-shaped frame having an elongated main arm and a pair of legs extending perpendicularly from the opposite ends of the main arm, the legs being parallel with respect to each other; b. a fixed anvil mounted on the outermost extending end of one of the legs of said frame and disposed to face the other of the legs; c. an elongated screw threadably mounted between its ends on the outermost extending end of the other of the legs of said frame and transversely positioned thereon to provide an inner end of said screw extending toward said fixed anvil and an outer end of said screw extending away from said fixed anvil; d. a movable anvil carried on the inner end of said elongated screw and disposed to face said fixed anvil for demountably attaching said frame to a support structure positionable therebetween; and e. an auxiliary clamp means in which an elongated workpiece is releasably holdable, said clamp means fixidly mounted on the main arm of said frame and oriented thereon to position the longitudinal axis of the workpiece perpendicular to the longitudinal axis of said elongated screw adjacent to the outer end thereof in a non-intersecting offset relationship, the amount of offset being approximately equal to one-half the diameter of said screw plus one-half the thickness dimension of the workpiece so that when the workpiece is held by said clamp means it may also be supported on the outer end of said elongated screw.
