Abstract: A bottomless, rectangular, elongated box type housing has a center section, a first outer section, and a second outer section. The center section is attached to a first section of the first outer section and a first section of the second outer section by hinges, which permit the first outer section and the second outer section to rotate rearwardly in a horizontal plane. A pin passes through apertures in gussets on the center section and the first section, thereby securing the first outer section in a forwardly extended position. Likewise, a pin passes through apertures in gussets on the center section and the second outer section, thereby holding the second outer section in a forwardly extended position. A hinge permits a second section of the first outer section to pivot vertically relative to the first section of the first outer section. Likewise, a hinge permits a second section of the second outer section to pivot vertically relative to the first section of the second outer section.

Abstract: An improved drift free spraying apparatus adapted for movement in connection with a vehicle and having a spray bar mounted within a bottomless, rectangular, box-type housing in communication with a fluid pump and reservoir assembly and adapted for emitting fluid in a mist configuration upon the surface to be sprayed through nozzles provided in the spray bar, the improvement comprising an elongated, bottomless, rectangular, box-type housing having first and second outer sections hingedly attached to a center section, an individual spray bar mounted within each section, means coupled to each spray bar for individual control of the emitting fluid to the spray bar, and means coupled to the first and second outer sections for selectively raising and lowering each section.

Abstract: A towable spraying device for attachment to a tractor, truck, or the like, for drift free spraying of chemicals such as herbicides and pesticides in a confined area in any wind condition. An elongated surface engaging spray housing is provided for attachment to a towing vehicle and includes an inner tubular member having a plurality of nozzles thereon for dispensing spray therefrom between fore and aft, elongated flexible baffles constructed upon the housing. The flexible baffles comprise lower portions of the fore and aft wall sections of the housing which permit same to engage and glide over rough terrain while substantially confining the spray therein. Spray such as insecticides can therein be applied to foliage and other ground surfaces in a controlled manner wherein extraneous contamination must be prevented.
