Abstract

Abstract An atomizing nozzle of the type used for discharging liquid agricultural chemicals into the air blast of an orchard sprayer, and including a discharge bell, or spinner cone, having external air vanes to spin the cone and centrifugally disperse the spray. The spray solution is directed into the cone by a fixed conduit and spray nozzle which are externally located with respect to the cone and its rotary mounting structure in order to eliminate internal flow passages from which the incoming spray solution might escape and cause corrosion or blockage to impair the operation of the nozzle.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 101 words
For use in an air blast orchard sprayer, a nozzle comprising a hollow nozzle cone extended at its apex by an outer cylindrical spinner body carrying spinner blades, a fixed shaft projecting from the center of a cup shaped part of a fixed support, for rotatably supporting said nozzle, said spinner body having a circular end face provided with spiral grooves extending from the center to the periphery thereof, vent holes being provided into said cup shaped part, and a nozzle supply tube external of said spinner body positioned so as to direct fluid into the apex of said nozzle cone.
Claim 2
Dependent Claim 101 words
For use in an air blast orchard sprayer, a nozzle comprising a hollow nozzle cone extended at its apex by an outer cylindrical spinner body carrying spinner blades, a fixed shaft projecting from the center of a cup shaped part of a fixed support, for rotatably supporting said nozzle, said spinner body having a circular end face provided with spiral grooves extending from the center to the periphery thereof, vent holes being provided into said cup shaped part, and a nozzle supply tube external of said spinner body positioned so as to direct fluid into the apex of said nozzle cone.
Claim 3
Dependent Claim 176 words
A spinning nozzle for an air blast sprayer comprising a support having a threaded shank for affixing one end of the support to a liquid supply manifold, said shank including an internal passage communicating with the manifold, an axle shaft extending axially from the other end of said support, a spinner cone having a body portion mounted on said axle shaft for free rotation, said spinner cone having an outwardly open end directed away from said axle shaft and outwardly extending spinner blades on said body portion for rotating said spinner cone in the air blast, said body portion having an end face confronting said support, said face being provided with slinger grooves radiating from said axle shaft to disperse liquid from said face by centrifugal force, and an exterior tube connected to said passage and terminating within the open end of said spinner cone, said tube having a streamlined section to minimize turbulence of the air blast and providing the only supply of liquid for centrifugal dispersion by said spinner cone into the air blast.
Claim 4
Dependent Claim 176 words
A spinning nozzle for an air blast sprayer comprising a support having a threaded shank for affixing one end of the support to a liquid supply manifold, said shank including an internal passage communicating with the manifold, an axle shaft extending axially from the other end of said support, a spinner cone having a body portion mounted on said axle shaft for free rotation, said spinner cone having an outwardly open end directed away from said axle shaft and outwardly extending spinner blades on said body portion for rotating said spinner cone in the air blast, said body portion having an end face confronting said support, said face being provided with slinger grooves radiating from said axle shaft to disperse liquid from said face by centrifugal force, and an exterior tube connected to said passage and terminating within the open end of said spinner cone, said tube having a streamlined section to minimize turbulence of the air blast and providing the only supply of liquid for centrifugal dispersion by said spinner cone into the air blast.
Claim 5
Dependent Claim 156 words
For use in an air blast orchard sprayer, a spinning nozzle assembly comprising a hollow open-ended spinner cone for distributing spray liquid outwardly thereof from its open end and having externally thereof at its closed apex end generally radially extending air-driven blades, a support disposed adjacent said cone apex end, a fixed shaft projecting from said support toward and rotatably journaled within said cone at its closed apex thereby to permit free rotation of said cone on said support when an air blast impinges against said blades, and a single supply passage for spray liquid comprising a tube carried by said support extending externally therefrom outside of saiD spinner cone and terminating in a reversely bent portion defining a discharge orifice disposed within the open end of said cone, whereby said spray liquid is discharged from said tube solely within said air-driven spinning cone for distribution outwardly therefrom and away from the rotatable shaft mounting therefor.
Claim 6
Dependent Claim 156 words
For use in an air blast orchard sprayer, a spinning nozzle assembly comprising a hollow open-ended spinner cone for distributing spray liquid outwardly thereof from its open end and having externally thereof at its closed apex end generally radially extending air-driven blades, a support disposed adjacent said cone apex end, a fixed shaft projecting from said support toward and rotatably journaled within said cone at its closed apex thereby to permit free rotation of said cone on said support when an air blast impinges against said blades, and a single supply passage for spray liquid comprising a tube carried by said support extending externally therefrom outside of saiD spinner cone and terminating in a reversely bent portion defining a discharge orifice disposed within the open end of said cone, whereby said spray liquid is discharged from said tube solely within said air-driven spinning cone for distribution outwardly therefrom and away from the rotatable shaft mounting therefor.
Claim 7
Dependent Claim 20 words
The spinning nozzle assembly of claim 3 further including a screw-threaded portion of said tube which defines said discharge orifice.
