Abstract: A portable wall and ceiling texture machine applicator is housed in a relatively small cabinet mounted on relatively large rear wheels for easy pulling up stairs and on swivel front casters for easy steering. A first material delivery system includes a variable speed pump which delivers particulate texture material at a selected flow rate which enables a creative application of texture.

Abstract: A stripper applicator employs a positive displacement gear pump to spray high viscosity stripper materials. The gear pump is driven at a reduced speed by an electric motor. A pressure relief valve is inserted in the outlet port of the gear pump to adjust the delivery pressure of the liquid. A large diameter suction line draws the liquid from a container to the pump without priming, and a dump line returns overflow liquid from the relief valve to the container. The stripper applicator is capable of delivering 1.5 gallons per minute of liquid at relatively low pressure to the delivery hose, which terminates in a spray gun. The electric motor and gear pump are mounted to a portable and light weight chassis.

Abstract: A hydraulic circuit and a wheeled self-propelled moveable frame provides a one-way feed of water under pressure selectively bearing a liquid soap or a liquid rinse chemical via a wind up hose mounted on a spool via a drive motor to axle to belt to clutch to shaft on the moveable frame through a multi-way directional valve to a water powered drive motor for driving the moveable frame forward and reverse relative to an open end of a vehicle body and said spool. A water cylinder changes the angle of inclination of a floor nozzle tube rotatable about its axis horizontally at the front of the moveable frame and bears a series of longitudinally spaced nozzles, when the machine travel reverses towards the open end of the vehicle body. The multi-way directional valve changes the water flow direction upon impact of a sensor operatively coupled thereto and projecting forwardly of the front of the wheeled self-propelled moveable frame.

Abstract: A spraying apparatus utilizes pressurized gas to spray liquid contained in a large replaceable or refillable cartridge. The cartridge is positioned within a casing which provides a pressure chamber, and a source of pressurized gas is attached to the casing to pressurize the chamber. The top of the cartridge communicates with the chamber so that the liquid is also pressurized. A tube extends from above the level of the liquid in the cartridge to the bottom of the cartridge and is attached to a valve. An opening is provided in the tube adjacent to the bottom of the cartridge, and the diameter of the tube is reduced above the opening to restrict the flow of gas through the tube and to create a pressure differential in the tube. When the valve is open, pressurized gas flows through the tube, and, since the pressure of the gas inside the tube at the opening is less than the pressure of the liquid, liquid flows through the opening, mixes with the gas within the tube, and flows through the valve.
