Patent Solicitors, 6, Lord Street, Liverpool and 6, Bank Street, Manchester both in
the County of Lancaster, 1-18, New Street, Birmingham in the County of Warwick,
and 322, High Holborn in the County of Middlesex, Civil Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to the construction of nozzles for firemen's and garden-hose
pipes, and it has for its object to provide a nozzle for hose pipes which shall be simple
in operation, economical, light in weight, and adapted to deliver the water in a
hollow-conical or funnel-shaped unbroken sheet, which will serve as a protection for
the firemen against smoke and heat and for wetting wide areas; or in a solid stream
so as to discharge a large volume and compact body of water in a short time for the
purpose of inundating the fire; or in both a hollow-conical or funnel-shaped and
unbroken sheet and a solid stream simultaneously to produce both of the above named
effects at the same time.
The invention consists, first, in a hose-pipe nozzle comprising a coupling or pipe
provided with a cock or valve, á tubular jet nozzle pipe supported within the mouth
of a hollow-conical spreading nozzle, and an adjustable spreading disk mounted in the
tubular jet nozzle.
Second, in a bore-pipe nozzle comprising a coupling or pipe provided with a cock.
or valve, a tubular jet nozzle placed within the mouth of a hollow-conical spreading
nozzle, an adjustable spreading disk mounted on the said tubular jet nozzle, and a
cap or plug fitted to the said jet nozzle to close the same.

A communication by ROBERT' H. ARMSTRONG, of 1210 Jefferson Avenue, Brooklyn,
in the County and State of New York, United States of America, Gentleman.
I, 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, 118 New Street, Birmingham, in the County of Warwick,
and 322, High Holborn, in the County of Middlesex, Civil Engineer, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
.
This invention relates to lie construction of nozzles for firemen's and garden-hose

page_text: pipes, and it has for its object, to provide a nozzle for hose pipes which shall be simple-
in operation, economical, light in weight, and adapted to deliver the water in a
hollow conical or funnel-shaped unbroken sheet which will serve as a protection for
the firemen against smoke and heat and for wetting wide areas; or in a solid stream
so as to discharge a large volume and compact body of water in a short time for the
purpose of inundating the fire; or in both a hollow conical or funnel-shaped and
unbroken sheet and a solid stream simultaneously to produce both of the above named
effects at the same time.
The invention consists, first, in a hose pipe nozzle, comprising a coupling or pipe
provided with a cock or valve, a tubular jet nozzle pipe supported within the mouth
of a hollow conical spreading nozzle and an adjustable spreading disk mounted in the
tubular jet nozzle.
Second: In a hose-pipe nozzle comprising a coupling of pipe provided with a
cock or valve, a tubular jet nozzle placed within the mouth of a hollow conical
spreading nozzle, an adjustable spreading disk mounted on the said tubular jet
nozzle and a cap or plug fitted to the said jet nozzle to close, the same.
In the accompanying drawing
Fig. 1 represents a side view of this improved nozzle ;
Fig. 2 a longitudinal section of the same taken transversely through the cock and
Fig. 3 a transverse section of the nozzle.
Referring to the drawing, A is the hose pipe provided with a cock B of the
usual or any desirable form suitable to the kind of hose with which the nozzle is
used. N is the hollow conical spreading nozzle which is made of a bell-shape, the
sides flaring outward at any suitable angle, and having a straight inner part or end a
which is screw-threaded in part to adapt it to make a screw connection with the hose
coupling. In this straight part also is a spider formed of two bars d, d, projecting
towards each other from opposite sides of the walls of the part a. Between these
arms the lower end of a tubular jet nozzle N' is secured in any suitable way. This
tubular jet nozzle is centrally fixed and projects a measurable distance beyond the
outer end of the bell-shaped nozzle, and it is screw-threaded exteriorly from its
extreme outer end to a point a short distance within the bell-shaped nozzle. D is a
spherical faced disk which is screwed on over the tubular jet nozzle with its spherical
face inside or towards the interior of the bell-shaped nozzle.
This disk may be
adjusted towards and from the end of the nozzle N and its diameter is slightly greater
than that of the nozzle so that when screwed home it will seat itself against the edge
thereof and close it, or, by securing it outward a continuous annular opening or
issue w is formed which may be reduced to a mere line adapted to deliver a thin spray,
or enlarged sufficiently to deliver a hollow stream of considerable volume. The inner
face of the disk being spherical it serves as a deflector by which the water is caused
to issue from the opening w in a broad circular or conical sheet of a diameter
depending on the pressure, and which sheet forms a protecting shield between the
hoseman and the fire, and which cools the air and drives the smoke and heat before
him. The jet nozzle N' on the other hand delivers a solid stream which can be played
on the point where a great volume of water is requisite to extinguish the fire. Where
the entire force and volume of water is required to fight the fire from a distance, as
from the outside of a house, for instance, the disk can be screwed down so as to
entirely close the nozzle N and all the water sent through the tubular jet nozzle, but
when the fire is being fought at close quarters and in a confined space, the nozzle N
can be opened and both the solid stream and the conical sheet or spray employed, in
order that the hoseman may be protected and enabled to manipulate the water in the
most effective manner.
The tubular nozzle N' may also be closed by means of a screw plug p which is adapted
to screw into the outer end of said nozzle (which is interiorally threaded for the purpose)
and the conical sheet spraying nozzle used alone. This may be of advantage when it
is desired to wet a large surface quickly and no great volume is required, and is
particularly advantageous where the nozzle is to be used with a garden hose or for a
fountain.

page_text: The screw plug p when removed, can be screwed for safety into a threaded socket s
in the enlarged part of the pipe. To retain the disk in the place to which it is
adjusted a set nut t may be screwed on the conical nozzle N'. To prevent injury to
the nozzle in case it should fall, a rubber gasket G may be placed around the nozzle N
near its mouth and on the outside so that when it drops, this being the heaviest part,
the rubber will take the blow and protect the nozzle.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :-
In a hose-pipe nozzle, the combination of a hose-pipe provided with a cock or valve,
a tubular jet nozzle suitably supported inside the mouth of the hose-pipe and within
the mouth of a hollow conical spreading nozzle, a cap or plug to close the same, and
an adjustable spreading disk mounted on the said tubular jet nozzle, whereby a
continuous circular exit or issue may be opened between the disk and the mouth of
the hose-pipe through which an unbroken conical or funnel-shaped sheet of water
may be discharged, while the solid stream through the tubular vent-pipe is shut off by
the cap or plug, substantially as specified.
