  • Pipe puller
    Patent number: 4483561
    Abstract: A pipe puller for pulling pipe from a stack of pipes is disclosed. The puller has an elongated handle and two spaced parallel legs extending from the handle. One leg is longer than the other. A stop plate is attached to the distal end of the longer leg so that when the shorter leg is inserted into the end of a flanged pipe, the stop plate engages and is disposed behind the flange on the pipe so that the pipe puller forms a convenient handle by which the pipe can be pulled from the stack of pipes.
