Abstract
Abstract Nozzle assemblies are provided which are effective for atomizing and mixing different or unlike fluids, and for combining the mixtures with solids and the like. The nozzle assemblies project the fluids, in the form of sprays or jets, which combine or mix at points or areas spaced forwardly of the nozzles, whereby clogging of the nozzles is avoided, and the separate fluids are prevented from contaminating each other within the nozzles or other parts of the assemblies. Nozzles of special or unique design are provided, which have an improved atomizing action.

Claim 1
Independent Claim
162 words
In a nozzle assembly of the character described, a body, a nozzle stem mounted in said body and having an axis and a plurality of passageways parallel with the axis of said nozzle and spaced equidistantly from said axis, said stem terminating at one end in a seat comprising a flat circular central portion, and a conical portion extending from the periphery of said circular portion to the external surface of said stem, said passageways extending to the conical portion of said seat, a cap or head seated on said seat, and provided with ports extending therethrough and communicating with said passageways, said ports being inclined toward each other, whereby to project fluids passing therethrough toward a common point or area spaced forwardly of said axis and substantially in alignment with said axis, and a ring or collar threadedly secured to said body and provided with a flange engaging said cap or head for retaining said cap or head in seated position.
