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.

Abstract: A backpack sprayer having a tank with a filling opening at the top thereof and a pressure chamber therein is provided with filtering apparatus for preventing particles in the fluid in the tank from entering an inlet port of the pressure chamber located near the bottom of the tank when suction generated by a pump that depends from the bottom of the pressure chamber causes fluid in the tank to flow through the inlet port into the pressure chamber. The fluid pressurized by the pump flows through an outlet port from the pressure chamber for spraying when a valve in the nozzle at the end of a hose communicating with the outlet port is actuated by an operator. The filtering apparatus is provided by a filter in a frame removably captured in a fixture projecting outwardly from the outside of the pressure chamber on opposite sides of the inlet port. A handle extends from the frame upwardly along the outside of the pressure chamber a sufficient distance to be accessed manually when the hand of the operator extends through the filling opening of the tank. The filter prevents particles, such as sediment, in the liquid at the bottom of the tank from flowing into the pressure chamber and pump mechanism thereof thereby preventing clogging of the pump mechanism and interfering with operation of the sprayer. The filter may be manually removed from the fixture for cleaning and then replaced. The need to totally disassemble the sprayer for cleaning is thereby substantially eliminated.

Abstract translation: 具有在其顶部具有填充开口的罐和其中的压力室的背包式喷雾器设置有过滤装置，用于防止罐中的流体中的颗粒进入位于罐底部附近的压力室的入口，当 由泵产生的从压力室底部引起的抽吸使得罐中的流体流过入口进入压力室。 当由操作者致动当与出口连通的软管端部处的喷嘴中的阀门时，由泵加压的流体流过来自用于喷射的压力室的出口。 过滤装置由可移除地捕获在从入口的相对侧上的从压力室外部向外突出的固定件中的过滤器提供。 当操作者的手延伸穿过罐的填充开口时，把手从框架向上延伸到足够的距离以便手动地接近压力室的外部。 过滤器防止在罐底部的液体中的颗粒（例如沉积物）流入压力室和泵机构，从而防止泵机构的堵塞并干扰喷雾器的操作。 过滤器可以从夹具手动移除，以进行清洁，然后更换。 从而基本上消除了完全拆卸用于清洁的喷雾器的需要。

Abstract: A backpack spray apparatus for applying insecticides and fertilizers comprises a large tank in which is mounted a pressure vessel. A pumping assembly is connected with the bottom portion of the pressure vessel and also with the bottom portion of the container tank. It consists of a double-acting piston assembly, a valve, and passages to connect a portion of the cylinder chamber above the piston assembly to the pressure vessel and to the container tank, so that upon reciprocation of the piston there is pumping of liquid from the container tank to the pressure vessel. There is also a connection between the portion of the cylinder chamber below the piston assembly and the lower portion of the container tank, so that upon reciprocation of the piston assembly there is pumping of the liquid back and forth. An operator-actuated handle reciprocates the piston assembly. There is no diaphragm associated with the pumping assembly--all pumping being done by the pumping assembly. Any liquid that leaks from the piston assembly does not drop onto the operator or the earth but instead joins liquid being pumped back and forth as above indicated.

Abstract: Sprayer apparatus with a molded container having a back-support panel for abutting relation with the back of a user while being carried, the container having attached, at the lower end thereof, a stand formed of bent tubing for supporting the container in a vertical position on a surface. A pressure vessel is centrally disposed within the container, with the lower portion of the pressure vessel having a threaded coupling fitting opening communicating with inlet and outlet passages. A fitting is threadably received within this opening, the fitting having passages communicating with the container and pressure vessel. A support plate is configured for detachably slidably securing directly to the lower part of the stand for support of a motor operated pump and battery, with the battery disposed inwardly relative to the bend of the stand, and the motor-pump outwardly thereof. Flexible tubing interconnects the pump and fitting. The motor-pump assembly is thus attached at the lowest part of the apparatus for stability, with the center of gravity of the motor-pump assembly generally centrally located relative to the lateral dimensin of the apparatus, and generally in line with the longitudinal centerline of the container. The assembly of support plate, battery, pump, motor and fitting is arranged as a unitary retrofit package to update the manual pump assembly of an existing sprayer, thus converting the manual sprayer into a motorized sprayer.

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 portable motorized fluid sprayer device is described, having a fluid tank and a pump manifold configured to pump fluid from the tank and into a connected fluid conveying structure (e.g., a hose, wand, nozzle, handle and/or similar structures). The manifold may include an electric motor, a gear pump, a controller, and a battery. Additionally, the fluid sprayer device may allow for spraying fluid with consistent pressure, recirculation of fluid within the tank, a gear pump for spraying or suctioning fluid from the fluid conveying structure, a safety lever, the ability to separate the pump manifold from the fluid tank, and other features.
