Patent ID: 6993949

Claim:
A grooving tool for forming a groove in a sidewall of a pipe circumferentially around said pipe, said grooving tool being capable of engaging a power drive unit for power operation thereof and a hand crank for manual operation, said grooving tool comprising: a housing; a grooving roller mounted on said housing and rotatable about a first axis, said grooving roller having a raised circumferential surface portion engageable with said sidewall for forming said groove; a back-up roller mounted on said housing adjacent to said grooving roller, said back-up roller being rotatable about a second axis, one of said grooving roller and said back-up roller being movable toward and away from the other of said rollers for positioning said sidewall between said rollers and forcibly engaging said rollers with said sidewall on opposite sides of said sidewall; a first shaft attached to one of said grooving and back-up rollers, said first shaft being engageable with said power drive unit, rotation of said power drive unit causing said first shaft and said one roller to rotate; a second shaft rotatably mounted on said housing, said second shaft being engageable with said hand crank; and a transmission mounted on said housing, said transmission extending between said first and said second shafts such that rotation of said second shaft causes rotation of said first shaft thereby rotating said one roller, rotation of said one roller by one of said power drive unit and said hand crank causing relative rotation between said pipe and said rollers for forming said groove.
