ABSTRACT:
Disclosed is a grease gun comprising a tubular casing having a grease pump attachment at one end and a cover at the other end which fits internally against the casing rim. A draw rod extends into the casing through the cover and carries an internal pressure collar with a compression spring acting between the cover and the pressure collar. A small section opening is provided in the casing at the pump attachment end for the expulsion of air from the casing. The draw rod can be clamped in position with respect to the cover by a clamping device and the design of the cover is such that when the draw rod is clamped in position and then pushed inwardly of the casing, movement of the cover in the casing is facilitated.
