  • Patent number: 7857239
    Abstract: A self-propelled and self-contained shrouded walking boom unit including a small tank and pump mounted on the unit. The unit also has a small transmission and DC drive which makes the unit self-propelled. The configuration is such that the operator walks in front of the spray applicator system with the spray being applied behind the operator. The operator steers the applicator and controls the spray from a handle attached to a single front steering wheel.

  • Patent number: 7063273
    Abstract: A spray delivery system including a sectional boom attachable to a vehicle. The boom includes first and second movable arms and a fixed arm, each arm housing a plurality of spray nozzles. Each arm can include a frame having openings so that the arms are light-weight and so that the nozzles housed in the frames for protection can spray through the openings in the bottom surface of the frame. The movable arms include an operation position and a retracted position and the arms each include a drift shroud covering to prevent wind from interfering with the application of spray from nozzles. The drift shrouds can include windows that align with the openings in the frame such that an operator can see the spray from the nozzle from the operator's seat in the vehicle.

  • Patent number: 5468183
    Abstract: An operator enclosure (12) for a commercial sprayer (10). A preferred enclosure (12) includes glass panels (30,32,34) only in the upper portion of the enclosure such that a fairly large gap is formed between the lower edges of the glass panels (30,32,34) and the chassis (16) of the sprayer (10). This gap enhances ventilation of the operator cab, particularly when the cab is pressurized by means of a blower-powered air cleaning system.

  • Patent number: 5433380
    Abstract: An injection type chemical sprayer (30) including interior and exterior cleaning systems. The interior cleaning system can include a rinsing nozzle (58) located within the concentrated chemical tank (52). Rinsing nozzle (58) can be selectively connected to the pressure side of a spray pump (34). The chemical rinsate can be dispensed by means of a rinsate pump (64) in combination with a rinsate nozzle (66). Following the rinsing operation, the concentrated chemical tank (52) can be reconnected to an injection pump (56), and then the concentrated chemical tank (52) can be filled with clean water which is then pumped through the injection system to completely flush it of the chemical being injected. System (30) also preferably includes an exterior cleaning system which can include a spray gun (60) selectively connected to the pressure side of the spray pump (34).
