Abstract
A device and method for coupling a pipe and a fitting. The device includes a pipe holder for releasably gripping a pipe, a fitting retainer for releasably retaining a pipe fitting substantially coaxially with a pipe in the pipe holder, and means for driving together the pipe holder and the fitting retainer along a longitudinal axis in a relative motion between them. The device may optionally slide a reinforcing sleeve along the pipe to cover the end of the pipe on the fitting.
Claims22
A device for coupling a pipe and a fitting, the device comprising
- a pipe holder for releasably gripping a pipe;
- a fitting retainer, for releasably holding a pipe fitting substantially co-axially with a pipe in said pipe holder;
- and
- a drive mechanism for driving together said pipe holder and said fitting retainer in a relative motion between them for coupling a pipe in said pipe holder to a fitting in said fitting retainer.

A method for coupling a pipe and a fitting, the method comprising:
- providing a pipe holder for gripping a pipe;
- providing a pipe fitting retainer for holding a fitting substantially coaxially with a pipe in said pipe holder;
- driving together said pipe holder and said fitting retainer in relative motion therebetween;
- and
- causing said pipe holder to retract when said pipe holder reaches a first pre-selected distance from said fitting retainer.
A method for coupling a pipe and a fitting, the method comprising:
- gripping a pipe by a pipe holder;
- retaining a pipe fitting by a fitting retainer;
- driving together said pipe holder and fitting retainer substantially along a common longitudinal axis in a relative motion between them until said pipe engages said fitting to form a joint;
- and
- retracting said pipe holder from said pipe.
