Abstract

A vise-like C-clamp with adjusting screw and wherein two elongated square bars are fixedly attached to one jaw thereof and the clamping end of the adjusting screw whereby a pair of gripping heads may be selected from a group of variously shaped heads and oppositely and interchangeably arranged on each of the bars. The clamp may be hand held or adjustably mounted in a supporting base for gripping and positioning variously shaped work pieces in horizontal, vertical, and angularly held positions while work is performed thereon.

Claims

1. A vise-like C-clamp for gripping variously regularly and irregularly shaped elongated work pieces therein comprising a shank with laterally extending arms at the opposing ends thereof, one of said arms having a fixed flattened clamping jaw, and the other of said arms formed with boss means supporting adjusting screw means therein, said screw means having clamping head means on an inner end thereof opposing said fixed clamping jaw, a pair of elongated generally square-shaped bar means extending transversely of and fixedly secured to said clamping head means and said jaw, said bar means being generally parallel and in alinement with each other, a pair of generally square-shaped tubular gripping head means spacedly sleevably and removably arranged on each of said bar means and each formed with clamping surfaces for interfitting and coacting with contoured work pieces to be clamped therein and therebetween whereby adjustment of said screw means moves said bar means and said gripping means thereon relative to the other of said bar means on said fixed clamping jaw to effect clamping of a work piece therebetween, at least one pair of said gripping head means formed with generally V-shaped clamping cavities and flat clamping surfaces on opposing sides of the square tubing means thereof, retaining means arranged on the ends of said bar means for preventing displacement of said gripping head means, and flat base means for supporting said C-clamp including spaced apart flat parallel plate means having bent flat base flanges secureable to said flat base surface whereby said plate means is upstanding therefrom, said shank being insertable between said plate means, and said shank and plate means being apertured to receive locking pin means therethrough to selectively retain and support said C-clamp in generally horizontal, angled, and vertical positions.

2. In a device according to claim 1, wherein at least one pair of said gripping head means is formed with generally triangularly-shaped clamping portions on one side of said square tubing means and flat clamping surfaces on opposing sides thereof.

3. In a device according to claim 1, wherein at least one pair of said gripping head means is formed with generally V-shaped clamping cavities on opposing sides of the square tubing means thereof.

4. In a device according to claim 1, wherein said pairs of gripping head means are interchangeably, selectively, and removably oppositely sleevably arranged on said bar means for gripping and clamping contoured work pieces therebetween, with said gripping heads being arranged in three differently formed pairs, with one pair including V-shaped clamping cavities and flat clamping surfaces on opposing sides of the tubing means thereof, a second pair including generally triangular-shaped clamping portions on one side of said tubing means, and a third pair including V-shaped clamping cavities on opposing sides of said tubing means, with the pairs to be sleeved on said bars being selected from said three pairs and arranged in opposing relation according to the particular contoured work piece to be clamped therebetween.

5. In a device according to claim 1, wherein said C-clamp is removably and adjustably supported between spaced apart flat parallel base plates mounted on and upstanding from flat base supporting surface means, said C-clamp being adjustable to horizontal, angled, and vertical positions in said base plates.
