Patent abstract
A tube extraction device which facilitates the removal of a tube from a tube hole in a drum. The tube extraction device comprises a housing which is mounted over an exterior surface of the drum. The housing has an opening which receives a removed part of the tube. A wedge having a slanted face and a bottom edge is slidably mounted in the housing. At least one side thrusting ram and at least one drive down ram are slidably mounted in the housing. The side thrusting ram laterally moves the wedge so that the slanted face indents the tube inwardly, while the drive down ram drives the wedge down into the tube so that the tube collapses in the tube hole.
