ABSTRACT:
The pneumatic greasing system is a grease delivery system specially designed to accommodate the standard commercial grease cartridges already on the market. In order to accomplish this the present invention comprises a cylindrical barrel comprising a cylindrical chute shaped to receive common cartridges. Either end of said barrel is attached to funnel shaped members that in turn have outlets. Inserted within said barrel is a circular disc comprising a rubber O-ring attached to its circumference. In one embodiment the grease is driven from the barrel by pressurized air impacting said disc. In a second embodiment the grease is driven from the barrel by suction applied by a pump against the surface of said disc.
