    Abstract: A portable backpack sprayer for spraying liquid chemicals such as pesticides, fungicides, and fertilizers having a large storage tank in which is mounted a pressure vessel. A manually actuated pumping assembly is connected with the bottom portion of the pressure vessel and also with the bottom portion of the tank. The pumping assembly comprises a reciprocating piston to draw liquid from the storage tank and pressurize it within the pressure vessel. The operator may discharge the pressurized liquid using a hose and a control valve affixed to the pressure vessel. The pumping assembly further comprises a double-walled piston and a leak barrier to collect any liquid that may leak from the piston. The reciprocating action of the piston is utilized to return the leaked liquid to the storage tank via a return siphon.

    Abstract: A portable, self-contained unit for the application of textured wall and ceiling covering material comprises a pressure tank adapted to be charged from an external source or by a manually actuatable pump incorporated in the tank. A pressure line containing a regulator connects the tank to an applicator gun having a longitudinally displaceable nozzle which directs the pressurized air across the bottom of a hopper containing textured material. Various tips for the gun are available to control the amount and texture of the material applied.

    Abstract: A sprayer attachment for a hand-supported power tool comprises a motion converting mechanism, a pumping mechanism, a spray assembly and a housing. The motion converting mechanism has an input shaft. The pumping mechanism is driven by the motion converting mechanism. The spray assembly is fluidly coupled to the pumping mechanism. The housing assembly couples the motion converting mechanism, the pumping mechanism and the spray assembly. The sprayer attachment may further comprise an anti-rotation bracket extending from the housing. The sprayer attachment may further be coupled to a handheld power tool, such as a cordless drill or a reciprocating saw, with the anti-rotation bracket.

    Abstract: A back pack sprayer apparatus for spraying liquids. The apparatus includes an integrally molded structure having an upper tank portion and a lower frame portion. A support stand can be connected to the molded structure, the support stand defining a supporting plane when the apparatus is in an upright position on the ground. The molded structure can have a front side defining a compound curve having an upper concave curve configured to receive an operator's back, and a lower convex curve terminating in a lowermost distal end forming a rearward angle of at least about 20 degrees with an axis normal to the supporting plane. The apparatus can include a pump, a hose, and a sprayer. A cover can be attached to the lower frame portion concealing the pump. The apparatus can include peripheral flanges and a lower drip rail which can help prevent liquid from contacting an operator.
