Improvements in Nozzles or Sprinklers, Applicable for Attachment
to Hose Pipes for Discharging Water in Jets or Spray or for
Cutting off the Discharge Completely.

I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool & 6 Bank Street, Manchester, both
in the County of Lancaster and 323 High Holborn in the County of Middlesex,
Civil Engineer, do hereby declare the nature of this invention to be as follows:-
-
This invention has for its object a nozzle or sprinkler for attachment to hose pipes,
for discharging either a stream or jet of water, or for discharging a round or crown
shaped spray, either coarse or fine, whichever is desired.
.
The main part or shell is provided with a conical plug or cone capable of revolving
therein, and on the same axis. The conical seating of said plug has two ports
or openings preferably on opposite sides, one of which leads to a chamber in
one end of the plug, and the other one leads through said chamber by a pipe
or channel, which terminates in an orifice of suitable shape. At the end of the
said pipe a collar is provided, adapted to the end of the aforesaid chamber in such
a way as to leave an annular opening of suitable width between the inside periphery
of the chamber, and the outside periphery of the collar. It will be therefore under-
stood that one of the ports on the seating of the plug or valve communicates with a
central orifice of circular or other shape, while the other communicates with an
annular orifice.
The seating in the shell or main portion of the apparatus is provided with one port
to which water from the hose pipe is supplied. The plug is inserted into the conical
seating of the base or shell, and secured by means of a screw and washer resting on
an annular shoulder forming part of the shell, but in a manner which does not prevent
the free rotation of the plug.
The mode of action is as follows:-
By rotating the plug once, its ports will coincide with the port in the conical seating
of the shell, by rotating it further the other port will coincide with the port in the
shell, or by a further rotation none of the ports will coincide with each other. Partial
rotation will therefore either permit liquid to pass out through the chamber and
through the annular orifice, producing an annular ribbon or crown spray, through the
tube producing a full stream or a central spray, or an entire cut off, whichever is
preferred. The strength or volume of the current may, of course, be adjusted.
As a modification, the nozzle or sprinkler may consist of a hollow main part having
a rose attached thereto a fixed interior bushing provided with openings to communicate
with the main part and the rose, a nozzle provided with means to communicate with
the main part and the rose said nozzle being adapted to turn axially in the bushing,

may have a rose, a bushing secured into the main part, and having a sido, and other

[, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E. of the Agency for Foreign
Patent Solicitors 6 Lord Street, Liverpool and 6 Bank Street Manchester both in
the County of Lancaster and 323 High Holborn in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention and in what manuer he
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
This invention has for its object a nozzle or sprinkler for attachment to hose pipes,
for discharging either a stream or jet of water, or a round or crown shaped spray,
either coarse or fine, whichever is desired.
In the accompanying drawings
Figure 1 shows a vertical section through one form of the improved nozzle.
Figure 2 is a cross section on line
arrows.
Figure 3 is a plan.
Figure 1 looking in the direction of the
Like letters indicate corresponding parts in all the Figures.
A nozzle constructed according to this invention consists of two main parts, a
shell A and a barrel B.
This shell A is hollow and provided with suitable means of attachment to a hose
pipe or the like, such as an internal screw a. Deponding within the said shell A
and preferably cast in one therewith is a conical seating A in which rests the lower
end or plug B of the barrel B.
The conical plug B' is provided in its sides with two openings or ports 6 6', either
of which may be caused to register with a corresponding port a' in the conical
seating A', by turning the plug B' within the shell A.
One of the ports 6 leads to a chamber C near the top of the barrel B, while the
other port communicates with a pipe C, which passes through the centre of said
chamber and projects slightly above the top of same. The pipe is preferably
fastened in place by being screwed into the bottom of the chamber (and its outer
end terminates in a jet orifice of suitable shape.
Near the outer end of the said pipe C¹, a cap plate or collar c is provided, adapted
to the end of the aforesaid chamber C in such a way as to leave an annular opening c
of suitable width between the inside periphery of the chamber and the outside
periphery of the collar. It will be therefore understood that one of the ports blon
the plug or valve communicates with a central orifice of circular or other shape,
while the other communicates with an annular orifice ².
The port a¹ in the conical seating A' communicates with the water supply. The
plug is secured in the seating by means of a screw E and spring washer e resting
on an annular shoulder forming the bottom of the seating, but in a manner which
does not prevent the free rotation of the plug.
The mode of action is as follows:-
By rotating the plug a certain distance, one of its ports b will coincide with the
ports a' in the conical seating of the shell; by rotating it further, the other ports b¹
will coincide with the port in the shell, or by a further rotation, none of the ports
will coincide with each other. Partial rotation will therefore either permit liquid
to pass out through the chamber and through the annular orifice producing an
annular ribbon, or crown spray; through the tube producing a full stream; or a
central spray, or an entire cut off, whichever is preferred. The strength or volume of
the current may, of course, be adjusted.

page_text: As a modification, the nozzle or sprinkler may consist of a hollow main part having
a rose attached thereto, a fixed interior bushing or conical seat provided with openings
to communicate with the water supply and the chamber surmounted by the rose, a
central nozzle provided with means to communicate with the main part and the rose,
suid nozzle being adapted to turn axially in the bushing, so as to shut off the water
or conduct it to the nozzle or to the rose in a similar manner to the above described
nozzle.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, as communicated to me by my
foreign correspondents, I declare that what I claim is :-
1. A hose nozzle consisting of a shell or main part, a conical seating A¹ depending
within it, having an opening a', a barrel having a chamber C, a tube leading through
said chamber, a conical plug at its lower end closely fitting seating A', openings in
said plug adapted to register with openings a', and leading to said chamber and said
tube, and a cap plate engaging said tube which closes said chamber with the
exception of a narrow circular opening surrounding said cap plate, substantially as
described.
2. The shell and conical seating having opening a' in combination with the
barrel having chamber C, central tube C₁, plug B, engaging within the conical
seating, and provided with openings and b, the latter being widened at its central
portion for the purpose set forth, and a cap plate nearly closing the outer end of said
chamber, whereby partial rotation of the barrel will permit water to pass out either
through the chamber producing a circular ribbon spray, through the tube producing
a full stream or a central spray, or will effect a perfect cut off, substantially as
described.
