Abstract: A hose end spray head apparatus includes a spread head body and a hose coupling. The spray head body includes a mixing body and a spray outlet arm formed as a unitary construction. The spray outlet arm extends outwardly from the mixing body and includes a spray bore to discharge a mixed fluid. The spray bore communicates with atmosphere via a first radial sidewall bore and a first offset top surface bore. An axial bottom surface bore extends from the bottom surface to the spray bore and is draws product from a container so as to inject the product into the spray bore. A second radial sidewall bore is configured to communicate an open interior of the container with atmosphere. The hose coupling is secured to the mixing body and mounts to a fluid supply to form the mixed fluid which is discharged through the spray bore.

Abstract: A dual chamber backpack sprayer system includes first, second and third tanks, and a pump unit. The first tank includes a first tank housing defining an open internal volume configured to hold a diluent therein. The second tank is dimensioned to be received within the internal volume of the first tank and is configured to hold a pressurized fluid therein. The third tank includes a third tank housing configured to hold a liquid concentrate therein. The pump unit is fluidly coupled to the first tank, the second tank and the third tank. The pump unit is configured to receive the diluent from the first tank and the liquid concentrate from the third tank to produce a mixed fluid. The mixed fluid is delivered to the second tank as the pressurized fluid.

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 spreader having a hopper for particulate material with discharge openings over two separate different areas along the hopper bottom, a pair of wheels upon separate drive shafts mounted for rotation to a lower frame which supports the hopper, and a rear frame extending from the hopper to provide a pair of handles. Two rotatable shafts with agitator elements are mounted over each of the different hopper areas. Each of the agitator shafts are coupled for rotation by different ones of the drive shafts. Two gates with openings are disposed below the hopper each along different ones of the areas dividing the hopper bottom. Each gate is movable to close and open the openings of the hopper in the area associated with the gate. A pair of controllers are provided each coupled to a different one of the two gates to independently move the gates between open and close positions.

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 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 spreader includes a frame having wheels mounted on an axle. A gear assembly on the axle is coupled with a shaft. A hopper is mounted on the frame and holds particulate that empties through an opening within the bottom wall. An impeller is mounted on the shaft and receives the particulate emptied from the hopper. A controlled-release assembly is mounted about the shaft and includes a drive housing secured to the hopper. The drive housing has a funnel opening to dispense the particulate therethrough. A transfer wheel within the drive housing is rotatably coupled to the shaft. When the shaft is rotating, the transfer wheel rotates whereby the particulate is delivered to the funnel. When the shaft is stationary, the transfer wheel is stationary whereby particulate is not delivered to the funnel.
