ABSTRACT:
A series of pipe manipulating tools having an elongated handle and a pipe engaging portion that grips a pipe when a force in a single direction is applied to the handle. A pipe engaging portion of a first pipe rotating tool has a first pivotally mounted arcuate jaw with a hand grip secured thereto, and a second arcuate jaw fixedly mounted to the handle. A spring biases the jaw members into clamping engagement with a pipe during use. Pipe engaging portions of second, third, fourth, and fifth pipe turning tools each have an arcuate member fixed to a handle, and at least one engagement tooth fixed at an end of the arcuate member for engaging a hook-receiving recess or protrusion on a bell end of an irrigation pipe. A pipe engaging portion of a sixth pipe tool includes an engagement tooth extending axially from a handle to engage a groove recess on a bell end of an irrigation pipe. The sixth pipe tool can be used to pull apart irrigation pipelines without gripping the bell end of the pipe by hand. A pipe engaging portion of a seventh pipe tool includes a U-shaped engagement member for pulling and lifting pipe that does not have a groove recess on the bell end. An eighth pipe tool is provided for lifting a male end of a pipe to facilitate alignment of the pipe ends during a connecting procedure.
