The sprayer comprises two main functioning units; namely, a flow control system incorporated in the chemical concentrate jar top closure and a spray nozzle integral with the closure for dispensing dilute solutions of fertilizer, pesticides and the like as supplied by the flow control system. The control system comprises an ejector for drawing concentrate from the reservoir jar and a pair of coaxial, independently rotatable valve elements, one, acting with fixed structure, serving to turn the water supply off or direct the water into the chemical concentrate jar or through the unit to the spray nozzle, the other, operating in conjunction with the first valve element, controlling by means of flow resistance in a labyrinth, desirably in conjunction with an orifice metering disc, proportionate feed from the jar of chemical concentrate to the main water stream. Proportionate feed may be accomplished without the flow resistance control by appropriate dimensioning of the ejector. The ejector is itself novel in that it is made of plastic material by injection with a single mold having a single core forming the entire length of the ejector passageway. The spray nozzle includes an adjustable, cam-controlled baffle for selectively achieving a downwardly or upwardly directed spread spray pattern or a jet stream.
In a hose-end sprayer comprising a chemical concentrate jar and a top closure having flow control means and a horizontal outlet snout therein and a spray nozzle supported thereby and connected through said snout with said flow control means for the flow of spray solution to said nozzle, the improvements comprising an open ended nozzle tube extending forwardly into said spray nozzle from said snout as an extension thereof, a hollow cylindrical hub extending forwardly from said snout, the inside diameter of said hub being greater than the outside diameter of said tube, a barrel mounted for rotation upon said hub, an elongated baffle longitudinally arranged within said barrel sidewise of said tube extended and hingedly secured to said barrel at a point intermediate the ends of said baffle, spring means for continuously urging said baffle out of line with said tube, upper and lower transverse cams secured within said barrel forwardly of the location at which said baffle is hingedly secured, said cams having substantially horizontal working faces defining chords of said barrel out of line with said tube, the arrangement being such that at one rotational position of said barrel said upper cam holds the forward portion of said baffle downwardly across the axis of said nozzle tube and at the opposite rotational position of said barrel said lower cam holds said forward portion of said baffle upwardly across the axis of said tube.
