Abstract
Abstract ABSTRACT OF THE DISCLOSURE The nozzle includes a sleeve and a hollow body concentrically disposed within the sleeve. A hollow cylindrical baffle housing is coaxially maintained within the body by vanes which extend between the housing outer wall and the body inner wall. Formed on the outer wall of the body is a thread which mates with a thread on the inner wall of the sleeve to permit rotation of the sleeve relative to the body between two stop positions. A baffle is secured to the baffle housing and is provided with a head which, as the sleeve is rotated toward the first stop position, approaches a baffle seat formed on the sleeve and thereby diminishes the quantity of liquid discharging from the nozzle. The sleeve is prevented from being rotted beyond the second stop position by two alternative modes: the female thread at its trailing edge is provided with an end wall which is disposed normal to the adjacent side walls of the thread and which, when the leading edge of the male thread is advanced into contact therewith prevents further advance of the male thread. Alternatively, the trailing edge of the male thread is provided with an enlarged portion which jams in the female thread when the sleeve is in the second stop position and prevents further rotation of the sleeve.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
134 words
A nozzle comprising a hollow body; a sleeve disposed about said body and having a thread formed on its inner wall which mates with a thread formed on the outer wall of said body to permit rotation of said sleeve relative to said body between first and second stop positions; a baffle secured to said body and having a head which, as the sleeve is rotated toward the first stop position, approaches a baffle seat formed on the said sleeve and thereby diminishes the quantity of liquid discharging from said nozzle; and stop means integral with the thread of one of said sleeve and said body and abutting against the other said thread when said sleeve is rotated to the second stop position to prevent further rotation of said sleeve in the same direction.
Claim 2
Dependent Claim
134 words
A nozzle comprising a hollow body; a sleeve disposed about said body and having a thread formed on its inner wall which mates with a thread formed on the outer wall of said body to permit rotation of said sleeve relative to said body between first and second stop positions; a baffle secured to said body and having a head which, as the sleeve is rotated toward the first stop position, approaches a baffle seat formed on the said sleeve and thereby diminishes the quantity of liquid discharging from said nozzle; and stop means integral with the thread of one of said sleeve and said body and abutting against the other said thread when said sleeve is rotated to the second stop position to prevent further rotation of said sleeve in the same direction.
Claim 3
Dependent Claim
192 words
A nozzle comprising a hollow body; a sleeve disposed about said body and having a baffle seat, one of said sleeve and said body having a female thread formed in its inner and outer wall respectively for mating with a male thread formed on the respective inner and outer wall of the other of said sleeve and body to permit rotation of said sleeve relative to said body between upstream and downstream stop positions, said female thread having spaced helically extending side walls which terminate at an end wall at the trailing edge of the thread, said end wall being disposed generally normal to said side walls adjacent thereto and abutting against the leading edge of the said male thread when said sleeve is at the upstream stop position, and preventing further upstream rotation of said sleeve said male and female threads throughout their extents between the upstream and downstream stop positions having uniform cross-sections and a baffle secured to said body and having a head which, as the sleeve is rotated toward the downstream stop position, approaches said baffle seat and thereby diminishes the quantity of liquid discharging from said nozzle.
Claim 4
Dependent Claim
192 words
A nozzle comprising a hollow body; a sleeve disposed about said body and having a baffle seat, one of said sleeve and said body having a female thread formed in its inner and outer wall respectively for mating with a male thread formed on the respective inner and outer wall of the other of said sleeve and body to permit rotation of said sleeve relative to said body between upstream and downstream stop positions, said female thread having spaced helically extending side walls which terminate at an end wall at the trailing edge of the thread, said end wall being disposed generally normal to said side walls adjacent thereto and abutting against the leading edge of the said male thread when said sleeve is at the upstream stop position, and preventing further upstream rotation of said sleeve said male and female threads throughout their extents between the upstream and downstream stop positions having uniform cross-sections and a baffle secured to said body and having a head which, as the sleeve is rotated toward the downstream stop position, approaches said baffle seat and thereby diminishes the quantity of liquid discharging from said nozzle.
Claim 5
Dependent Claim
149 words
A nozzle comprising a hollow body; a sleeve disposed about said body and having a baffle seat, one of said sleeve and said body having a female thread formed in its inner and outer wall respectively for mating with a male thread formed on the respective inner and outer wall of the other of said sleeve and body to permit rotation of said sleeve relative to said body between upstream and downstream stop positions, said male thread having at its trailing portion an enlarged member which contacts the leading portion of the female thread when said sleeve is at the upstream stop position and thereby prevents further upstream rotation of said sleeve; and a baffle secured to said body and having a head, which as the sleeve is rotated toward the downstream stop position, approaches said baffle seat and thereby diminishes the quantity of liquid discharging from said nozzle.
Claim 6
Dependent Claim
149 words
A nozzle comprising a hollow body; a sleeve disposed about said body and having a baffle seat, one of said sleeve and said body having a female thread formed in its inner and outer wall respectively for mating with a male thread formed on the respective inner and outer wall of the other of said sleeve and body to permit rotation of said sleeve relative to said body between upstream and downstream stop positions, said male thread having at its trailing portion an enlarged member which contacts the leading portion of the female thread when said sleeve is at the upstream stop position and thereby prevents further upstream rotation of said sleeve; and a baffle secured to said body and having a head, which as the sleeve is rotated toward the downstream stop position, approaches said baffle seat and thereby diminishes the quantity of liquid discharging from said nozzle.
Claim 7
Dependent Claim
57 words
The nozzle as claimed in claims 1, 2 or 3 wherein said baffle is secured to said body by means of a hollow cylindrical baffle housing coaxially maintained within said body by three only vanes disposed equi-distantly about said housing and extending radially between the outer wall of said housing and the inner wall of said body.
Claim 8
Dependent Claim
76 words
The nozzle as claimed in claims 1, 2 or 3 wherein said baffle is secured to said body by means of a hollow cylindrical baffle housing coaxially maintained within said body by three only vanes disposed equidistantly about said housing and extending radially between the outer wall of said housing and the inner wall of said body, the length of each said vane being not less than about 1/3 of the total length of said body.
Claim 9
Dependent Claim
73 words
The nozzle as claimed in claims 1, 2 or 3 wherein said sleeve is provided at its outlet end with an annular wall from which extend a plurality of spaced radially disposed teeth each having a length measured on a line which extends radially and normally from the longitudinal axis of said sleeve, which length is at least 10% of the length of the radius of the outer circumference of said annular wall.
