Clamp and press for joining dual pipes

Claim 1

A clamp for gripping one pipe only of a multiple side-by-side pipe assembly comprising a pair of pivotally connected bowlforming bodies with registering complementary cavities of sufficient diametral expanse to encompass the pipe assembly, a plurality of wedging slips in said cavities, at least first and second sets of registering complementary recesses in the inner surfaces of said slips receiving individual pipes of said assembly, and gripping teeth in the surfaces of said first set of recesses, the outer surfaces of said slips and the mating surfaces of said bowl cavities being inclined to the axis of the Bowl cavities whereby, upon application of opposed longitudinal forces to said clamp and a pipe in said first recesses, said teeth will be forced radially inwardly to grip the pipe therein, there being sufficient clearance between said second slip recesses and the pipe therein to accommodate the radial wedging movement of said slips without binding of said slips against said latter pipe, and means for securing together said body bowls.
