ABSTRACT:
A self aligning clamp for fixturing two items of unequal thickness together in a stationary relationship in a vice device prior to joining the items together by welding or the like is disclosed. The self aligning clamping device has a fixed rigid lower jaw adapted to receive an underside of the two items of unequal thickness together in a stationary co-planar relationship, the lower jaw being disposed transversely to the vice device and further having a lower region adapted for releasable communication with a lower extent of the vice device, each jaw still further having a solid cylindrical shape for urging continuous, rigid, unbending contact communication with the upper side of each item. Further the clamping device has a swivel having paired, spaced apart, downwardly disposed jaws adapted to receive an upper side of the two items of unequal thickness together in a stationary non-planar relationship, each downwardly disposed jaw being oriented above the lower jaw and being disposed parallel to the vice device. The swivel further has an aperture in a middle region adapted for threadable, rivetable communication with an upper extent of the vice device, and each jaw still further has a solid cylindrical shape for urging continuous, rigid, unbending contact communication with the upper side of each item.
