Abstract: A conventional liquid spray gun having a compressed air supply equipped with a liquid, e.g. paint, container for supplying the liquid to be sprayed onto a target surface. The container has a closed bottom, an open top and a cylindrical sidewall. A removable cover is attached over the open top of the container, and the cover has a pair of apertures extending through it, one of which holds a proximal end of a rigid tube whose distal end extends to a point close to the container's bottom. Slidingly mounted on the rigid tube is a generally circular, movable plunger whose periphery engages the cylindrical sidewall of the container. Pressurized air injected through the second aperture in the cover forces the plunger against the liquid's surface and causes the liquid to flow through the lumen of the rigid tube to the liquid inlet port of the spray gun.

Abstract: A hand-held, battery powered liquid applicator (10) having an on-board reservoir (15). An electric motor drives a piston (20) in the reservoir via a pinion gear member (70) and rack gear (28). A gear shifter (68) may disengage the pinion gear member (70) from the rack gear (28). A battery compartment (78) may have a door (88) has recess to enable a user to grasp a dry cell located farthest from the door. The rack gear (28) may have modified profile teeth at the end of travel to allow the pinion gear member (70) to slip when the piston (20) is urged past the end of travel. The piston (20) may have a length substantially equal to a characteristic length of the reservoir (15). Liquid may be drawn into the reservoir by powered or manual retraction of the piston and liquid may be delivered from the reservoir to an applicator head by powered or manual motion of the piston into the reservoir.
