Abstract: A backpack sprayer system includes a mounting bracket having a battery receiving fixture. A first tank is mounted to the mounting bracket and holds a diluent. A second tank is mounted to the mounting bracket and holds a liquid concentrate. The second tank is selectively, individually removable from the mounting bracket. A mixing manifold is mounted to the mounting bracket and has a first inlet fitting to receive a fixed amount of diluent and a second inlet to receive an adjustable amount of liquid concentrate. The diluent and concentrate are combined to form a mixed solution with the mixing manifold including a mixed solution outlet. A positive displacement pump is mounted to the mounting bracket and has a suction port coupled to the mixed solution outlet and a pressure port coupled with a spray device. A control unit is mounted on the mounting bracket and receives power from the battery.

Abstract: A sprayer system includes a diluent tank, a mounting bracket mounted to the diluent tank and a concentrate tank mounted to the mounting bracket and diluent tank. A mixing manifold is mounted to the mounting bracket and has a first inlet fitting to receive a fixed amount of diluent and a second inlet to receive a liquid concentrate. The diluent and concentrate are then combined to form a mixed solution. The mixing manifold includes an outlet. A positive displacement pump is mounted to the mounting bracket and has a suction port fluidly coupled to the mixed solution outlet. A pressure port may fluidly couple with a spray device. The second tank may be separable from the first tank and mounting bracket without requiring removal of the mixing manifold or positive displacement pump.

Abstract: A dosing cap for dispensing a measured dose of material includes a housing, a sealing member and a biasing member. The housing has an inlet end residing within a container and receives the material. An outlet end dispenses the material. A dosage region is interposed between the inlet end and outlet end. The sealing member is received within the housing. The sealing member includes a first seal proximate the inlet end to selectively open or close the inlet end and a second seal proximate the outlet end to selectively open or close the outlet end. When the biasing member is unbiased, the inlet end is open, the outlet orifice is closed and the dosage region is charged with material. When the biasing member is compressed, the sealing member is biased so that the inlet end is closed and the outlet orifice is open whereby the material is dispensed.

Abstract: A fluid injection device includes a housing and a valve stem. The housing includes an inlet arm having an inlet orifice for receiving a feeder fluid. An outlet arm has an outlet orifice to discharge a mixed fluid. A venturi tube is between the inlet and outlet arms. The inlet arm, veturi tube and outlet arm define a nonlinear fluid pathway where the venturi tube redefines a portion of the nonlinear fluid pathway as a constricted fluid pathway. A diverter port is used to divert a portion of the feeder fluid from the inlet arm into the container and an injection port is used to receive product from the container. A valve arm is collinearly aligned with the venturi tube and the valve stem is positioned within the valve arm and adjusts the volume of the constricted fluid pathway.

Abstract: A walk from behind, also called a push or cart sprayer having an assembly of wheeled frame and a tank. The frame has a rearward extending handle which enables the assembly to be pushed along a path. The tank has a connected boom assembly including a pivotal boom arm along the front of the tank with a distal spray nozzle, and a mechanism enabling the boom arm to be pivoted to the sides of the tank where the nozzle sprays away from the path, to the side of the path, so that possible toxic or corrosive spraying liquid cannot be stepped upon by the operator pushing the sprayer, thereby enhancing safety of operation. The boom arm is also pivotal to the front of the tank, such as useful when the cart sprayer is towed.

Abstract: A hand-held spreader is provided having a housing with a compartment for particulate material, a chamber below the compartment having a bottom wall with a circular aperture, an impeller mounted for rotation in the chamber along such bottom wall responsive to a hand crank, a discharge opening, and a path along which the particulate material passes into the chamber for discharge via the discharge opening. The impeller has an outer circular periphery proximal to and extending over an outer edge of the aperture to form a gap between the impeller and the bottom wall of the chamber that seals the gap from the particulate material larger than the gap from entering under the impeller and risking obstruction of impeller rotation. Any particulate material that enters the gap passes downward through the aperture to enable self-cleaning of particulate material that would otherwise collect under the impeller in the chamber.
