Patent ID: 7232167

Claim:
A cam-action pipe puller for pulling and extracting a pipe from and through a conduit comprising a plurality of grasping members each having an outer serrated surface formed to engage a portion of the inner side of the pipe so as to enable the pipe pulling and extracting apparatus to pull and extract the pipe, and pulling and extracting apparatus having a top cap having a diameter enabling the top cap to slidably move along the inner side of the pipe and having retainer means for engaging a lower end of the grasping members and guiding the pipe pulling and extracting apparatus into the pipe as the pipe pulling and extracting apparatus is initially inserted into the pipe with a top diameter of the grasping members greater than the inside diameter of the pipe thereby preventing further entry of the grasping members into the pipe and for releasing the lower ends of the grasping members after being further inserted into the pipe so that the grasping members top diameter is less than the pipe inside diameter thereby enabling the pipe puller to slidably move along the inner sides of pipe and having a cam for expanding the released ends of the grasping members to engage the inner side of the pipe when subsequently pulled outward from the pipe to pull and extract the pipe.
