Irrigation sprinkler nozzle
First Claim
1. An irrigation sprinkler nozzle of the type including a nozzle housing having a range nozzle portion formed by a generally cylindrical converging passageway adapted to project a columnated water stream outwardly over a relatively long distance, and a spreader nozzle portion disposed vertically below said range nozzle portion and adapted to project a water spray outwardly over a relatively short distance, said spreader nozzle portion comprising:
- an elongated chamber formed in said housing below said range nozzle passageway, said chamber having a generally rectangular cross-section defined by spaced top and bottom generally horizontally disposed walls, and laterally spaced generally vertical side walls;
water inlet means formed in said housing upstream of said range nozzle passageway for directing water into one end of said chamber; and
water outlet means at an end of said chamber remote from said one end for producing a generally vertically oriented fan shaped spray of relatively narrow lateral width, said water outlet means being oriented such that an upper portion of said fan shaped spray intercepts said stream from said range nozzle.

Abstract
An irrigation sprinkler nozzle comprising a nozzle body having a range nozzle passage therethrough and a spreader nozzle disposed therebelow, the spreader nozzle being formed by a generally rectangular cross-sectional chamber having a generally rectangular cross-sectional outlet orifice, the chamber and outlet orifice being oriented with their long dimensions extending in a generally lateral direction substantially horizontal with the ground, the outlet orifice being laterally but not vertically smaller in size than the size of the chamber so that a vertically oriented fan-shaped spray pattern is produced by water projected from the outlet orifice.

7. An irrigation sprinkler nozzle of the type including a nozzle housing having a range nozzle portion formed by a generally converging passageway leading to a range nozzle outlet and adapted to project a water stream outwardly over a relatively long distance, and a spreader nozzle portion disposed below said range nozzle portion and adapted to project a water spray outwardly over a relatively shorter distance, said spreader nozzle portion comprising:
-
an elongated chamber formed in said housing, said chamber having a generally rectangular shaped cross-section defined by vertically spaced top and bottom walls and laterally spaced side walls; water inlet means formed in said housing upstream of said range nozzle outlet for directing water into one end of said chamber; water outlet means at an end of said chamber remote from said one end, said outlet means having a generally rectangular shaped outlet opening of a cross-sectional size larger than the cross-sectional size of said inlet means, said outlet opening being formed by vertically spaced upper and lower walls coextensive with said vertically spaced top and bottom walls, and laterally spaced generally vertically directed end walls disposed laterally inwardly of said laterally spaced side walls, whereby water flowing from said inlet means to said outlet through said chamber is laterally but not vertically constricted as it passes through said outlet opening to produce a generally vertically oriented fan shaped spray. - View Dependent Claims (8, 9, 10)
