ABSTRACT:
A pipe fitting apparatus for holding a pair of pipe fittings together such that the pipe fittings may be welded. The apparatus is designed for use by a single operator. The apparatus comprises a pair of handles interconnected by a conventional locking toggle apparatus and having first and second clamping jaws extending from the handles such that the first and second clamping jaws may be clampingly engaged with a first pipe fitting. A lower support extends from one of said clamping jaws and provides adjustable support for a lower portion of a second pipe fitting adjacent to the first pipe fitting. An upper support provides supporting engagement for a distal upper end of the second pipe fitting and includes an arm holder attached to one of the clamping jaws and a support arm slidably connected to the arm holder and which may be locked in a supporting position. The arm holder provides pivotation of the support arm in two axes so that the support arm may be moved as necessary to accommodate different sizes and shapes of fittings.
