Patent ID: 7409893

Claim:
A method of installing a pipe coupling onto pipes and fittings, comprising the steps of: providing a tool having a handle; a knife portion extending from the handle, the knife portion having a tip end, the tip end having a first thread engaging edge, and a second thread engaging edge; placing the pipe coupling onto the pipes and fittings, the pipe coupling having a first set of flanges and a second set of flanges, each set of flanges having an aperture therethrough for receiving a bolt; installing a first bolt having a threaded end into the aperture on the first set of flanges and loosely connecting a first nut onto the threaded end of the first bolt; squeezing the second set of flanges of the pipe coupling together; inserting a second bolt having a threaded end into the aperture on the second set of flanges, wedging the tip end of the tool against the threaded end of the second bolt such that the first thread engaging edge and the second thread engaging edge engage the threads of the second bolt; releasing the second set of flanges thereby preventing the pipe coupling from springing open and the second bolt from coming out of the aperture on the second set of flanges; fastening the first nut on the first bolt; and fastening a second nut on the second bolt.
