Patent ID: 7673860

Claim:
A clamp comprising: a plurality of clamping assemblies, a first of said clamping assemblies comprising two opposing clamping jaws that have first-shaped clamping surfaces, said clamping jaws being movably mounted on support structure for movement towards and away from each other; and a second of said clamping assemblies comprising two opposing clamping jaws that have second-shaped clamping surfaces which are shaped differently than said first-shaped clamping surfaces and which are movably mounted on support structure for movement towards and away from each other, wherein said second-shaped clamping surfaces comprise non-parallel clamping surfaces such that two workpieces clamped between said non-parallel clamping surfaces are fixed at a non-parallel angle with respect to each of said opposing jaws, wherein said non-parallel opposing clamping jaws comprise a first jaw including a V-shape channel and second jaw including X-shape channels, and wherein each of said clamping jaws of said clamping assemblies are actuated along a threaded shaft wherein rotation of said threaded shaft moves said clamping jaws linearly along said threaded shaft.
