Abstract:
An apparatus and a method of extracting buried lead water supply pipe with minimal excavation and which allows removal and containment of the lead pipe. The extraction apparatus includes a frame having an upwardly extending mast, a guide pulley mounted on the frame, and a pulling apparatus mounted on the mast. A take-up spool is mounted on the mast between the guide pulley and pulling apparatus and positioned to force a pipe pulling cable into a non-linear path between the guide pulley and the pulling apparatus. Extracted pipe is pulled into the non-linear path until the pipe is fully extracted from the ground. Multiple spiral loops around the take-up spool by the pulling cable may be necessary to fully contain the extracted pipe. Following extraction, the pipe may be unspooled from the take-up spool, the pulling cable removed for re-use, and the pipe may then be sent for disposal.

Claim (Index 4):
The pipe extraction apparatus of  claim 3 , wherein the height adjusting mechanism includes a telescoping portion disposed in the mast enabling spacing between the base frame and a distal end of the mast to be adjusted.
