Abstract: A bung tool has a cylindrical body with a four-armed drive portion projecting from one end thereof and a six-armed drive portion projecting from the opposite end thereof, respectively for engagement with different types of bungs. A drive member reciprocates in a square cross-section axial bore through the body, being manually moveable by a handle which projects radially through a slot in the body. The drive lug of an associated drive lever is receivable in the opposite ends of the bore for respectively driving the two drive portions. The drive member reciprocates among two recessed positions respectively spaced from the opposite ends of the bore to allow insertion of the drive lug therein and a drive position projecting from one of the drive portions for driving engagement with a bung cap.

Abstract: A tool includes a solid block body unitary with a plurality of equidistantly spaced-apart blades which project from the body in the same direction, each blade having flat planar opposed faces with the faces of all of the blades being parallel to one another. The faces of each blade are chamfered at the distal ends thereof and are spaced apart by a pair of opposed parallel side surfaces, each inclined to the planes of the faces at an angle which approximates the complement of the helix angle of an associated spring, to facilitate insertion of the blades between the spring convolutions when the spring is extended, to maintain it in its extended condition.
