Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
230 words
A side discharge liquid spray nozzle comprising a body with a rear end and a front end and having an external plain groove extending across the body from side to side thereof, the body having an air supply passage therein which leads forwardly from the rear end of the body toward the front end thereof to one side of the bottom of the groove and discharges across the bottom of the groove to the opposite side thereof, said air supply passage having means to supply thereto a gaseous medium under positive pressure, the body also having a liquid supply passage therein which leads rearwardly from the front end of the body toward the rear end thereof to one side of the bottom of the groove and discharges across the bottom of the groove to the opposite sides thereof, the groove having the bottom thereof extending transversely of the air supply passage and liquid supply passage and at right angles thereto and of uniform cross-section from end to end of the groove, the groove having at least one side which curves outward from the supply passages, said air supply passage and said liquid supply passage terminating at a point opposing one another at the bottom of the groove causing air and liquid discharged from the passages into the groove to impinge one on the other and emerge in a spray pattern.
Claim 2
Dependent Claim
230 words
A side discharge liquid spray nozzle comprising a body with a rear end and a front end and having an external plain groove extending across the body from side to side thereof, the body having an air supply passage therein which leads forwardly from the rear end of the body toward the front end thereof to one side of the bottom of the groove and discharges across the bottom of the groove to the opposite side thereof, said air supply passage having means to supply thereto a gaseous medium under positive pressure, the body also having a liquid supply passage therein which leads rearwardly from the front end of the body toward the rear end thereof to one side of the bottom of the groove and discharges across the bottom of the groove to the opposite sides thereof, the groove having the bottom thereof extending transversely of the air supply passage and liquid supply passage and at right angles thereto and of uniform cross-section from end to end of the groove, the groove having at least one side which curves outward from the supply passages, said air supply passage and said liquid supply passage terminating at a point opposing one another at the bottom of the groove causing air and liquid discharged from the passages into the groove to impinge one on the other and emerge in a spray pattern.
Claim 3
Dependent Claim
35 words
A side discharge liquid spray nozzle as in claim 1 wherein the external plain groove is of substantially uniform cross-section and is in substantially a straight line which is substantially perpendicular to said supply passages.
Claim 4
Dependent Claim
34 words
A side discharge liquid spray nozzle as in claim 1 wherein the external plain groove is of substantially uniform cross-section and wherein the ends of the groove curve toward one end of the nozzle.
Claim 5
Dependent Claim
225 words
In a side discharge liquid spray nozzle comprising a body with a rear end and a front end and having an external plain groove extending across the body from side to side thereof, the body having liquid supply passage therein which leads rearwardly from the front end of the body toward the rear end thereof to one side of the bottom of the groove and discharges across the bottom of the groove to the opposite side thereof, the groove having the bottom thereof extending transversely of the liquid supply passage and at right angles thereto and of uniform cross-section from end to end of the groove, the improvement comprising an air supply passage therein which leads forwardly from the rear end of the body to the front end thereof to one side of the bottom of the groove and discharges across the bottom of the groove to the opposite side thereof, the groove having at least one side which curves outward from the supply passages, said air supply passage having means to supply thereto a gaseous medium under positive pressure, said air supply passage and said liquid supply passage terminating at a point opposing one another at the bottom of the groove causing air and liquid discharged from the passages into the groove to impinge one on the other and emerge in a spray pattern.
Claim 6
Dependent Claim
225 words
In a side discharge liquid spray nozzle comprising a body with a rear end and a front end and having an external plain groove extending across the body from side to side thereof, the body having liquid supply passage therein which leads rearwardly from the front end of the body toward the rear end thereof to one side of the bottom of the groove and discharges across the bottom of the groove to the opposite side thereof, the groove having the bottom thereof extending transversely of the liquid supply passage and at right angles thereto and of uniform cross-section from end to end of the groove, the improvement comprising an air supply passage therein which leads forwardly from the rear end of the body to the front end thereof to one side of the bottom of the groove and discharges across the bottom of the groove to the opposite side thereof, the groove having at least one side which curves outward from the supply passages, said air supply passage having means to supply thereto a gaseous medium under positive pressure, said air supply passage and said liquid supply passage terminating at a point opposing one another at the bottom of the groove causing air and liquid discharged from the passages into the groove to impinge one on the other and emerge in a spray pattern.
Claim 7

35 words
A side discharge liquid spray nozzle as in claim 4 wherein the external plain groove is of substantially uniform cross-section and is in substantially a straight line which is substantially perpendicular to said supply passages.
Claim 8
Dependent Claim
34 words
A side discharge liquid spray nozzle as in claim 4 wherein the external plain groove is of substantially uniform cross-section and wherein the ends of the groove curve toward one end of the nozzle.
