Abstract
Abstract A spray nozzle apparatus and a method of making a spray nozzle in which a variety of nozzle sizes can be made using several common components. The nozzle head has a threaded base for attachment to a water line which base has an opening passing therethrough for mounting removable nozzle inserts therein with retainer rings. A water-deflecting portion is removably mounted to the base so that a curved portion thereon will deflect water at a predetermined angle. The curved deflector is attached to the base with a single screw and a pair of positioning studs.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
171 words
A spray nozzle comprising in combination: a threaded base for attachment to a water line, and having an opening therethrough and a plurality of bores therein; a removable nozzle insert mounted in said opening through said base with a retainer ring and having an opening therethrough of a predetermined size, and an exterior of predetermined size and shape for fitting into the opening through the threaded base; a removably mounted water-deflector member, having a curved water deflecting surface and having attaching means for attaching said water-deflector to said base, said attaching means having at least one insert attached to said water-deflector member and protruding into one of said plurality of bores in said threaded base, whereby an easily assembled spray nozzle is provided; and a flow control member mounted adjacent said removable nozzle insert retainer ring in said opening in said threaded base, said flow control member being a flexible member which under increased pressure is flexed into said nozzle insert retainer ring to reduce the passageway through said retainer ring.
Claim 2
Dependent Claim
171 words
A spray nozzle comprising in combination: a threaded base for attachment to a water line, and having an opening therethrough and a plurality of bores therein; a removable nozzle insert mounted in said opening through said base with a retainer ring and having an opening therethrough of a predetermined size, and an exterior of predetermined size and shape for fitting into the opening through the threaded base; a removably mounted water-deflector member, having a curved water deflecting surface and having attaching means for attaching said water-deflector to said base, said attaching means having at least one insert attached to said water-deflector member and protruding into one of said plurality of bores in said threaded base, whereby an easily assembled spray nozzle is provided; and a flow control member mounted adjacent said removable nozzle insert retainer ring in said opening in said threaded base, said flow control member being a flexible member which under increased pressure is flexed into said nozzle insert retainer ring to reduce the passageway through said retainer ring.
Claim 3
Dependent Claim
27 words
The apparatus in accordance with claim 1, in which said removable nozzle insert is positioned over an O-ring for sealing said nozzle insert in said threaded base.
Claim 4
Dependent Claim
27 words
The apparatus in accordance with claim 2, in which said threaded base removable nozzle insert and removably mounted water deflector member are formed of a polymer material.
Claim 5
Dependent Claim
35 words
The apparatus in accordance with claim 3, in which said threaded base and said removably mounted water-deflector are of one color and said nozzle insert and retainer ring are of a second size, identifying color.
Claim 6
Dependent Claim
23 words
The apparatus in accordance with claim 4, in which said removably mounted water-deflector member has an open top covered with a disc-shaped cap.

Claim 8
Independent Claim
117 words
The method of making a spray nozzle comprising the steps of: molding a threaded base having an opening therethrough and a plurality of bores extending into one end thereof; inserting a nozzle insert of predetermined size in said opening through said threaded base; locking said nozzle insert in said threaded base with a retainer ring press-fitted thereover; molding a water-deflector of predetermined shape, including the molding of said water-deflector with a pair of protruding studs positioned in a predetermined position for inserting into a pair of said bores in said threaded base, and screwing a threaded member through said curved deflector member into a third bore in said base; and attaching said molded water-deflector to said base.
Claim 9
Independent Claim
117 words
The method of making a spray nozzle comprising the steps of: molding a threaded base having an opening therethrough and a plurality of bores extending into one end thereof; inserting a nozzle insert of predetermined size in said opening through said threaded base; locking said nozzle insert in said threaded base with a retainer ring press-fitted thereover; molding a water-deflector of predetermined shape, including the molding of said water-deflector with a pair of protruding studs positioned in a predetermined position for inserting into a pair of said bores in said threaded base, and screwing a threaded member through said curved deflector member into a third bore in said base; and attaching said molded water-deflector to said base.
Claim 10
Dependent Claim
23 words
The method in accordance with claim 7, including the step of pressure-fitting a disc cover over the top of said water deflector member.
Claim 11
Dependent Claim
37 words
The method in accordance with claim 7, including the step of inserting an O-ring in said opening through said base prior to inserting said nozzle insert for sealing said nozzle insert in said opening through said base.
Claim 12
Dependent Claim
37 words
The method in accordance with claim 9, in which a color coded disc retainer ring and nozzle insert are assembled onto said water deflector member for indicating the size of the nozzle insert inserted into said base.
