Abstract
Abstract A fire hose nozzle of the high constant gallonage class positions a cylindrical stream pattern sleeve for reciprocal motion around and about a beveled discharge orifice in the nozzle which includes a centrally positioned baffle. A rotatable dial on the nozzle has a cam channel therein engaging a detent on the cylindrical sleeve for imparting reciprocal motion thereto, the cam channel being so formed that rotation of the same to predetermined positions locates the pattern forming sleeve so as to provide a straight stream, narrow fog or wide fog patterns as desired.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
107 words
A nozzle having a body defining a conduit having an inlet end and an outlet end, a sleeve telescopically positioned about said body having a stream forming portion extending beyond said outlet end, a circular baffle carried by said body and positioned adjacent said outlet end thereof, said body and sleeve including co-acting means to cause relative longitudinal movement, said means including a perpendicular pivot on said body extending outwardly through a longitudinally extending slot in said sleeve, a cam body rotably mounted on said perpendicular pivot, a cam channel in said cam body adjacent said sleeve and a detent on said sleeve engaging said cam channel.
Claim 2
Dependent Claim
107 words
A nozzle having a body defining a conduit having an inlet end and an outlet end, a sleeve telescopically positioned about said body having a stream forming portion extending beyond said outlet end, a circular baffle carried by said body and positioned adjacent said outlet end thereof, said body and sleeve including co-acting means to cause relative longitudinal movement, said means including a perpendicular pivot on said body extending outwardly through a longitudinally extending slot in said sleeve, a cam body rotably mounted on said perpendicular pivot, a cam channel in said cam body adjacent said sleeve and a detent on said sleeve engaging said cam channel.
Claim 3
Dependent Claim
31 words
The nozzle of claim 1 and wherein the cam channel is of irregular configuration so as to move the sleeve in different degrees relative to said rotation of said cam body.
Claim 4
Dependent Claim
35 words
The nozzle of claim 1 wherein said channel has depressions therein therealong, and a spring urged ball in said detent registers with said depressions to hold said cam body in predetermined relation to said detent.
Claim 5
Dependent Claim
25 words
The nozzle of claim 1 and wherein said outlet end of said body has an annular bevel extending inwardly to an area of smaller diamer.
Claim 6
Dependent Claim
23 words
The nozzle of claim 4 and wherein said circular baffle is of larger diameter than said area of smaller diameter in said body.
Claim 7
Dependent Claim
18 words
The nozzle of claim 1 and wherein said baffle is carried on a web centrally of said body.
Claim 8
Dependent Claim
27 words
The nozzle of claim 1 wherein indicia on said cam body corresponds with predetermined positions of said sleeve relative to said body and the resultant discharge pattern.
Claim 9
Dependent Claim
40 words
The nozzle of claim 1 wherein said cam body is circular and an indicia carrying flanged cap is positioned thereover and secured thereto so that rotary motion imparted said cap and body will move said sleeve longitudinally of said body.
