Abstract
A handable clamp such as a vice grip, carrying a pair of interlocking arcuate-faced extension jaws, one of which is laterally projecting on both sides of clamp jaws and formed with parallel-sided tongues and guide slots spaced apart by aliquot distances, whereby selection of a pair of such walls as guides for saw blade will enable severance of chosen arc-length of clamped ring. The thus-matching butt-ends of the ring can then be secured together to form a ring of smaller size. The projecting jaw tongue and slot pattern is reproduced with indicia on associated reference surface, such as a decal, to indicate position of particular pairs of cuts corresponding to chosen arc length.
Claims5
A composite clamp assembly comprising a clamp having a pair of adjustable clamp jaws and means for functionally opening and closing same, each clamp jaw carrying an extension jaw having clamp faces of corresponding transverse arcuate curvature and disposed in position to clamp an arcuate segment of a workpiece such as a ring therebetween, one extension jaw consisting of an arcuate surfaced plate laterally projecting beyond one of said clamp jaws, such projecting portion being characterized by at least one longitudinal tongue forming an open-ended guide slot having mutually parallel side walls extending adjacent a side of the clamp jaw, each side of said slot and of said tongue thus forming guide walls jointly defining different arc lengths of a clamped workpiece, the width of said slot and of said tongue corresponding to aliquot parts of an arcuate unit distance, whereby a desired arc length of a clamped workpiece may be severed by making cuts along a selected pair of said guide walls as by moving a juxtaposed sawblade therealong, said clamp assembly including interlocking means for preventing lateral displacement of one extension jaw relative to the other when in functional engagement.
