ABSTRACT:
Disclosed is an apparatus and method for connecting a fitting to a side wall of a pipe. The apparatus includes a frame comprising two ring clamps for mounting the frame on the pipe. Guide rods extend perpendicularly and outwardly of the pipe. A base plate is slidably mounted on the guide rods for movement relative to the pipe. A receiving member on the base plate is adapted to receive the fitting to be joined to the pipe. A top bar is fixedly attached between the ends of the guide rods remote from the rings. A threaded shaft is positioned with one end attached to the receiving member and with its second end passing through the top bar. Within the top bar are means for selectively engaging the threaded shaft so that the shaft may be translated through the top bar by turning the shaft. Alternatively, the shaft may be disengaged from the top bar whereby the shaft may be moved freely through the top bar. In operation, the threaded shaft, and thus the receiving member and fitting attached thereto, may be advanced toward the pipe during the joining of the fitting to the pipe by pushing the threaded shaft through the top bar when the threaded shaft is not engaged with the top bar or by turning the threaded shaft when the threaded shaft is engaged with the top bar.
