page_text: I, FRANK MOORE of 15 Richard Street Cornwall Road Lambeth in the county
of Surrey 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:-
:
The object of my invention is to produce a nozzle by which one two or three or
more jets or streams of water or other liquid can be produced and ejected at pleasure
and shut off when required very simply quickly and easily and this my improved
nozzle is applicable with all fire engines hydrants hoses pipes and other similar
appliances for whatever purposes the same may be used but it is more especially
applicable with portable fire extinguishers which are now so continually and
increasingly coming into general use.
In order the more clearly to explain my invention I refer to the accompanying
drawing in which I have shewn one of these my improved nozzles as fitted to
deliver one or two or three jets or streams of water or other liquid.
Figure 1. is an elevation and Figure 2 is a longitudinal section of this nozzle.
The other figures shew different parts of this nozzle as will hereafter be fully
detailed!
.
On the end of a pipe hose branch or other similar appliance A is screwed or
otherwise' secured' a cap B' the top or end of which is closed and the face C thereof
is turned or made a true flat face. In this face C and through the closed top or
end of the cap B'are formed three apertures D E and F'as shewn in Figure 4 which
is a plan of the said face C. A ring or collar H is passed up over and round this
cap B and an internal flange H¹ on the lower edge of the said ring or collar H
engages'a shoulder formed' therefor round the top or end' of the said cap B. Into this
ring or collar H is screwed or otherwise secured the nozzle K in which are formed
or which consists of three passages L for the liquid which is to be ejected which
passages L may either be parallel with each other as shewn in the drawing or may
diverge from or converge to each other and may be of the same diameter throughout
also as shewn in the drawing or may be tapered or may be otherwise arranged and
formed as I may deem expedient in each particular case but the lower or entrance
mouths of these passages L in the base of the said nozzle K in all cases are so

page_text: arranged and formed as duly to correspond or to communicate with the aforesaid
apertures D E and F as is hereafter more particularly explained and as is shewn in
Figure 3 which is a plan of the underside of the said nozzle K. A central stud or
pivot is made on the underside of the nozzle K or as in this case where there are
three jets or streams a projecting collar L¹ is formed round the central passage L
which can enter a central socket in the face C of the cap B or as in this case
where there are three jets or streams the central aperture E in the said face C is
made large enough to receive the said collar L' or the pivot may be formed on the
cap and the socket in the nozzle as may be desired. The base of the nozzle K is
and must be circular to screw into or fit the ring or collar H but the upper part of
the said nozzle K. may be formed in any convenient style' and shape when the
whole apparatus is made as shewn in the drawing preferably as shewn in Figure 5
which is a transverse section taken at a. b. in Figure 2. When the ring or collar H
is passed into position the nozzle K is screwed thereinto until the base of the said
nozzle K on which also is turned or made a true flat face is in contact with the
face C of the cap B when a set screw M is passed through the said ring or collar H
into a recess made therefor in the said nozzle K or in other usual or convenient
manner the said nozzle K is firmly and tightly fixed and secured in position in and
to the said ring or collar. H. Thus the nozzle K with the ring or collar H can
obviously be turned round on the cap B as desired being assisted and regulated in such
revolution by the central pivot- L1 and to render such movement the easier of
accomplishment the outside of the said ring or collar H can be roughed or be
otherwise treated to enable the operator to obtain a firm grasp thereon.
In Figures 6. 7 and 8 I have shewn diagrams of the various positions of the two
meeting faces of the nozzle and the cap hereinbefore described to produce the
desired effect of delivering one and two and three jets or streams of water or other
liquid as may be desired.
In Figure 6 the passages L coincide with--and are opposite to the apertures
DE and F and therefore three jets are delivered. This position is also shewn in
Figure 2.
When the nozzle K is turned into the position indicated in Figure 7 the aperture D
is no longer coincident with and opposite to the one passage L but the central
aperture E still coincides with and is opposite to the central passage L as obviously
when the apparatus is made as shewn in the drawing and as described must always
be the case as the projecting mouth L¹ of the central passage L constitutes the
pivot on which the said nozzle K turns and the elongated aperture F is so formed
as to be still coincident with and opposite to the third passage L and therefore only
two jets are delivered.
When the nozzle K is turned into the position indicated in Figure 8 the central
aperture E as aforesaid still coincides with and is opposite to the central passage L
but the other apertures D and F are not coincident with and opposite to the other
passages L and therefore only one jet is delivered.
Thus and in this manner the number of jets or streams that issue from this nozzle
can be increased or diminished at will without interfering with the antecedent
flow of the liquid or disconnecting the nozzle from the tube or pipe or other
appliance through which the liquid is delivered into this nozzle as is desired.
In like manner I can fit as indeed is sufficiently obvious any other number of
apertures and passages in the nozzle producing a corresponding number of jets but
I always preferably use an odd number so that the central passage and aperture
inay form the central pivot and socket as is herein before described and as is shewn
in the drawing.
It is also very obvious that I do not limit myself to the exact shapes and
proportions and details of construction as shewn in the drawing for all the several
parts of this nozzle may be made of such shapes and proportions and be so fitted
and connected together as may be expedient or desirable or convenient in each
particular case.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The arrangement of apparatus substantially as herein before described and as
shewn for delivering one or more jets or streams at will through a nozzle.
2. The combination of the nozzle K with passages L the cap B with apertures
DE and F and the ring or collar H with flange H¹ substantially as and for the
purpose herein before described and declared.
