Abstract: There is disclosed a grease gun including a chamber with a cap on one end and head on the other end. Inside the head is a cavity which may receive grease from the chamber. Part of the cavity forms a cylinder in which reciprocates a piston. The piston in turn operates a ratchet on its upward stroke, as grease fills the cylinder. The ratchet turns a rod on which is threaded a follower. The rotation of the rod moves the follower towards the head and forces grease into the cavity and thus into the cylinder. On the downward stroke, the piston is disengaged from the ratchet and forces grease out of the cavity into a discharge conduit. Valves control movement in and out of the cavity. The ratchet is rotatably mounted outside of the chamber. Also, the grease gun preferably includes a split nut threaded on the rod adjacent the follower and a shoulder adjacent the cap and oriented to split the split nut on engagement with the split nut. A setting ring is used to reset the split nut.

Abstract: A single stroke pressure viscous liquid pump for discharging highly viscous and filled, abrasive liquids under pressure sufficient for spray coating a surface with such liquids. The device includes an upright liquid tank having an open upper end positioned atop a base plate of a frame in coaxial alignment spaced directly beneath a pressure cylinder which includes an axially movable ram having a piston at its lower end. The piston is sized to sealingly engage the inner surface of the tank whereby downward axial force generated by the ram is transmitted directly against the upper surface of the liquid within the tank. A discharge outlet near the bottom of the tank is connectable to a conduit and liquid spray nozzle for spray application of the pressurized liquid discharged from the tank outlet. Only a single downstroke of the ram is required at a very slow feed rate to empty the tank of liquid, thus eliminating virtually all heat buildup.

The fixed handle has a widened portion intermediate the ends thereof.

Abstract: A viscous-material dispensing gun is presented which has a front material receiving portion and a rear drive portion. The front of the gun is loaded with viscous material and snapped into place by means of a locking collar and pins. The front conical portion of the gun is attached by thumbscrews.
