Abstract

A picture framer'"'"'s tool of the type used to drive brads into picture frames shown in U.S. Pat. No. 4,763,825 is modified so that it may also be used as a clamp. The tool has two jaws, namely an inner adjustably positioned along a sleeve and a second jaw on the outer end of a rod reciprocable within the sleeve and extending beyond the outer end of said sleeve. The tool has a lever pivoted on a handle which causes the rod to reciprocate. One improvement is the provision of a wing screw or other fastener on the handle which engages the rod so that it is fixed in position. Another improvement is the provision of attachments for each jaw, one of which may be spring-loaded. Attachments include hammer heads, points, swivels and the like.

Claims

1. A combination picture framing and clamp tool comprising a handle fixed to a sleeve extending therefrom, said handle being formed with a bore aligned with said sleeve, a rod reciprocable in said bore and sleeve and extending out beyond said sleeve, manually operable means on said handle to cause reciprocation of said rod within said sleeve and bore to cause movement of said rod toward and away from said handle in minute increments, a normally fixed first jaw on said sleeve, a movable second jaw on said rod opposed to said first jaw, and rod restraining means on said handle to engage said rod to restrain movement of said rod relative to said handle at any position of adjustment of said second jaw relative to said first jaw, said restraining means comprising a first screw threaded into said handle and bearing against said rod at a first position and a second screw threaded into said handle and bearing against said rod at a second position opposite said first position.

2. A tool according to claim 1 in which said first jaw is adjustably positionable along said sleeve.

3. A combined picture framing and clamp tool comprising a handle fixed to a sleeve extending therefrom, said handle being formed with a bore aligned with said sleeve a rod reciprocable in said bore and sleeve and extending out beyond said sleeve, manually operable means on said handle to cause reciprocation of said rod within said sleeve and bore to cause movement of said rod toward and away from said handle in minute increments, a normally fixed first jaw on said sleeve, a movable second jaw on said rod opposed to said first jaw, and rod restraining means on said handle to engage said rod to restrain movement of said rod relative to said handle at any position of adjustment of said second jaw relative to said first jaw, in which said first and second jaws are formed with opposed outward extending anvils, at least one said anvil being formed with a hole and which further comprises a plurality of fittings selectively positionable in said hole and means to secure one of said fittings in said hole, said hole being formed with a threaded counterbore, said fitting comprising a head extendable through said second hole, a collar behind said head to engage the bottom of said counterbore and a shank on the end of said fitting opposite said head, said last-mentioned means comprising a threaded second sleeve threaded into said counterbore, a spring, and a nut on the outer end of said second sleeve, said spring bearing against said nut and said shank to resiliently bias said head outward of said jaw.
