Abstract
Abstract A spray nozzle adapted to eject a radial spray around its entire periphery comprising a plastic nozzle element having an axial bore adapted to produce an axial jet and secured at its base in a metal supporting ring and a transverse deflector plate disposed in the path of the jet to deflect the same radially outwardly to form a 360* spray pattern. The deflector plate is formed by a plastic disc or liner shaped to the deflector surface and carried by a metal support element.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
85 words
A spray nozzle comprising a plastic element having a bore through which the spray liquid passes and having an inlet end and a discharge tip, a supporting ring of rigid material adapted to be attached to a coupling member and surrounding at least a portion of the outer surface of the plastic element, said plastic element and said supporting member having interlocked tongues and grooves for securing the plastic element in place, with the supporting ring having peripheral grooves into which said plastic is molded.
Claim 2
Dependent Claim
85 words
A spray nozzle comprising a plastic element having a bore through which the spray liquid passes and having an inlet end and a discharge tip, a supporting ring of rigid material adapted to be attached to a coupling member and surrounding at least a portion of the outer surface of the plastic element, said plastic element and said supporting member having interlocked tongues and grooves for securing the plastic element in place, with the supporting ring having peripheral grooves into which said plastic is molded.
Claim 3
Dependent Claim
20 words
A spray nozzle as set forth in claim 1 in which said grooves are undercut for securing said plastic therein.
Claim 4
Dependent Claim
