Improvements in Atomizers for Spraying Liquids applicable also
for Fire-extinction,
I, CHRISTIAN ALBERT JENSEN, of No. 77, Chancery Lane, in the County of
Middlesex, Chartered Patent Agent, do hereby declare the nature of this inven-
tion, a communication to me from abroad by Otto Schütz and Alexander Pfund,
both of No. 11, Corso. Brescia, Turin, in the Kingdom of Italy, Engine-fitters, to
be as follows: -
The atomisers used hitherto for moistening the air do not allow of regulating
the outflow of the water and they are so complicated and imperfect that an
efficient moistening of the surrounding air can not be obtained, nor can they be
used as fire-extinguishing devices.
The subject of the present invention is an atomiser in which the outflowing
spray can be regulated by means of two or more orifices, which can be shifted
to more or less coincide one. with regard to the other. It is obvious that by
suitably adjusting these orifices an exact regulation can be obtained.
The atomiser is provided with four adjustable exit orifices corresponding to
four jets of water. The water is supplied through a supply pipe, to which the
whole apparatus may be attached. This pipe terminates at its lower end in a
bell provided with four lateral openings. The bell is enclosed in a casing having
also four openings. The casing may be turned slightly round the bell by means
of a lever the outer end of which meshes with a screw which is mounted in suitable
bearings. By turning this screw, for instance by means of a suitably arranged
sprocket wheel and chain, the orifices can be adjusted with such minuteness that
a very fine spray-jet will be obtained.
In order to uniformly distribute these four jets a ring is provided, surrounding
the orifices at a suitable distance. This ring is made preferably in the form of
a double ring and is provided with curved faces on which the jets strike and from
which the water rebounds, being thereby finely and uniformly distributed. The
inner ring and the outer ring have holes which may or may not coincide with
each other.
When these holes are adjusted in such a way that the outer holes coincide
entirely with the inner ones, four strong jets stream out, having however another
direction than that of the fine jets aforesaid. These jets, namely, do not strike
then against the faces but stream out through the openings or holes in the double
ring.
Besides this the ring is provided with curves or cut out parts for the purpose
of allowing the, full jets to stream out below the ring if desired. It will be
seen that by these means an efficient besprinkling of the room-will be obtained.
The apparatus can be easily cleaned when it is used for fire-extinguishing
purposes. To this end a cap is let down which catches up the jets, so that all
parts of the apparatus are thoroughly washed. The cap is screwed and is mounted
on a screw, so that by turning it, it can be let down. The cap may have of
course various forms, it may for instance be funnel shaped, by which when it is

page_text: raised, the air is conducted to the spray jets in order to obtain a very complete
dispersion of these jets.
The lower part of the apparatus is formed of a funnel serving to lead off the
water.
-
According to a modification as shewn there are curved faces from which the
jets rebound; these faces being preferably carried by spiral springs. The said
faces are enclosed by funnels serving to produce an efficient distribution of the
spray. Apart from these modifications the construction of the apparatus does not
materially differ from that of the apparatus first described.

Improvements in; Atomizers for Spraying Liquids, applicable also
for Fire-extinction.
I, CHRISTIAN ALBERT JENSEN, of No. 77, Chancery Lane, in the County of
Middlesex, Chartered Patent Agent, do hereby declare the nature of this inven-
tion, (a communication to me from abroad by Otto Schütz and Alexander Pfund,
both late of No. 11, Corso Brescia, Turin, in the Kingdom of Italy, but now of
No. 133, Wilmersdorfer Strasse, Charlottenburg, near Berlin, in the German
Empire, Engine-fitters) and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:-
The atomizers used hitherto for moistening the air do not allow of regulating
the outflow of the water and they are so complicated and imperfect that an
efficient moistening of the surrounding air can not be obtained, nor can they be
used as fire-extinguishing devices.
The subject of the present invention is an atomizer, in which the outflowing
spray can be regulated by means of two or more orifices which can be shifted to
more or less coincide one with the other. It is obvious that by suitably adjusting
these orifices an exact regulation can be obtained.
The new atomizer is represented in the accompanying drawing,
Fig. 1 being a vertical section of the apparatus and
Fig. 2 a horizontal section on the line 2-2 of Fig. 1.
Fig. 3 is a somewhat modified form of the atomiser in elevation.
Fig. 4 is a detail in elevation and
Fig. 5 represents a modification partly in elevation and partly in section.
The atomizer is provided with four adjustable exit orifices corresponding to
four jets of water. The water is, as shown in Figures 1 and 2, supplied through
a supply pipe h, to which the whole apparatus may be attached. This pipe
terminates at its lower end in a bell provided with four lateral openings. The
hell is enclosed and fits in a casing having also four openings a.
The casing may
be turned slightly round the bell by means of a lever i the outer end of which
takes into the thread of a screw k (Fig. 2) which is mounted in suitable bearings.
By turning this screw, for instance as shown by means of a suitably arranged
sprocket wheel and chain, the orifices can be adjusted with such a minuteness
that a very fine spray-jet will be obtained.
In order to uniformly distribute these four jets a ring 61 is provided. sur-
rounding the orifices at a suitable distance. This ring is made preferably in the
form of a double ring and is provided with curved faces c on which the jets strike

page_text: and from which the water rebounds (see Fig. 4 shewing the developed inner ring)
being thereby finely and uniformly distributed. The curved surfaces care
portions of the metal ring 6 and are made by stamping out portions of the metal.
The inner ring and the outer ring have holes which may or may not coincide
with each other.
When these holes are adjusted in such a way that the outer holes coincide
entirely with the inner ones, four strong jets stream out having however another
direction than that of the fine jets. These jets, namely, do not then strike
against the faces c but stream out through the openings or holes d of the double
ring bb (see Fig. 3, shewing the completed outer ring). Besides this the double
ring is provided with curves or cut out parts for the purpose of allowing the
full jets to stream out below the ring if desired. It will be seen that by these
means an efficient besprinkling of the room will be obtained.
The apparatus can be easily cleaned when it is used for fire-extinguishing pur-
poses. To this end a cap e Fig. 1 is let down which catches up the jets, so that
all parts of the apparatus are thoroughly washed. The cap is screwed and is
mounted on a screw surrounding the pipe h so that by turning it, it can be let
down. The cap may of course be made in various forms, it may for instance be
funnel-shaped, by which, when it is raised, the air is conducted to the spray jets
in order to obtain a very complete dispersion of these jets. The bottom m of the
cape slides down together with the latter until it touches the top of the ring 6, 61
when the cap continues to fall alone. When the apparatus is used as an atomizer
the cap is let down and retains the spray within the apparatus.
The lower part of the apparatus consists of a funnel 7 serving to carry off
the water.
According to a modification and as shewn in Fig. 5 there are curved faces f
from which the jets rebound; these faces being preferably carried by helical
springs. The said faces f are enclosed by funnels g serving to produce an efficient
distribution of the spray. Apart from these modifications the construction of
the apparatus does not materially differ from that of the apparatus shewn in
Figs. 1 and 2.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I claim
as the invention communicated to me is:-
._
1. An atomizer consisting of a supply pipe, a distributor having openings which
may be adjusted with relation to each other, and a pair of rings extending about
the distributor and adjacent to each other and having openings, said rings being
adjustable in relation to each other to vary the openings of the two rings in
relation to each other and also in relation to the openings in the distributor, said
rings when adjusted remaining in position until manually changed.
2. In an atomizer the combination of the distributor having the openings, the
ring surrounding the same and having perforations and curves ', the funnel Z
below the ring and distributor and the cover movable towards and from the
funnel 7, substantially as described and shewn.
3. The constructions of atomizers as described and shewn on the drawing.
