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.
