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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
109 words
In a nozzle assembly of the character described, a body having passageways for flow of separate fluids therethrough, a nozzle or stem mounted in said body and having parallel passageways communicating with said first-named passageways, said stem having a conical surface at its upper end, said second-named passageways terminating at said conical surface, said stem having spaces offset inwardly from said terminal ends of said second-named passageways, but in communication with said terminal ends, and a cap mounted on said stem and having a conical lower surface seated on said first-named conical surface, and effective to cause fluids emerging from said second-named passageways to be diverted into said spaces.
Claim 2
Dependent Claim
109 words
In a nozzle assembly of the character described, a body having passageways for flow of separate fluids therethrough, a nozzle or stem mounted in said body and having parallel passageways communicating with said first-named passageways, said stem having a conical surface at its upper end, said second-named passageways terminating at said conical surface, said stem having spaces offset inwardly from said terminal ends of said second-named passageways, but in communication with said terminal ends, and a cap mounted on said stem and having a conical lower surface seated on said first-named conical surface, and effective to cause fluids emerging from said second-named passageways to be diverted into said spaces.
Claim 3
Dependent Claim
22 words
A nozzle assembly, as defined in claim 1, including means secured to said body for maintaining said cap in said seated position.
Claim 4
Dependent Claim
39 words
A nozzle assembly, as defined in claim 2, wherein said stem is milled at its upper end to provide a plurality of said spaces, which are non-communicating with each other, and said cap is effective to prevent such communication.
Claim 5
Dependent Claim
94 words
In a nozzle assembly of the character described, a nozzle stem having passageways for flow of separate fluids therethrough, said stem having a conical surface at its upper end, said passageways terminating at said conical surface, said stem having spaces offset inwardly from said terminal ends of said passageways, but in communication with said terminal ends, and a cap mounted on said stem and having a conical lower surface seated on said first-named conical surface, and effective to cause fluids emerging from said terminal ends of said passageways to be diverted into said spaces.
Claim 6
Dependent Claim
94 words
In a nozzle assembly of the character described, a nozzle stem having passageways for flow of separate fluids therethrough, said stem having a conical surface at its upper end, said passageways terminating at said conical surface, said stem having spaces offset inwardly from said terminal ends of said passageways, but in communication with said terminal ends, and a cap mounted on said stem and having a conical lower surface seated on said first-named conical surface, and effective to cause fluids emerging from said terminal ends of said passageways to be diverted into said spaces.
Claim 7
Dependent Claim
20 words
A nozzle assembly, as defined in claim 4, including means for securing said cap in seated position on said stem.
Claim 8
Dependent Claim
39 words
A nozzle assembly, as defined in claim 5, wherein said stem is milled at its upper end to provide a plurality of said spaces, which are non-communicating with each other, and said cap is effective to prevent such communication.
