Improvements in Spray Diffusing Apparatus.
I EMIL HEINRICH CONRAD OEHLMANN of 7 Gentbiner Strasse, Berlin in
the German Empire, 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 apparatus for producing or diffusing sprays of water
for air humidifying and ventilating purposes and consists in the use and arrange-
ment of mouthpieces to the water supply pipes with one or more pairs of nozzles,
the mouths of the two nozzles in each pair being placed near to and facing each
other and on the same axis so that the jets of water issuing from said nozzles meet
each other and break up into fine spray, one of the nozzles being cup shaped or
conically recessed so that the spray becomes spread or diffused in the shape of a
hollow cone.
On the drawing appended hereunto
Fig. 1 shows a side view and Fig. 2 a section of my improved spray diffusing
mouth piece with one pair of nozzles ;
Fig. 3 a mouth piece with two pairs of nozzles ;
Fig. 4 the application of the same to an air humidifying apparatus.
My improvement consists in the combination in one mouthpiece attached to the
water supply pipe of one or more pairs of nozzles a 6 having the same axis, one of
which nozzles is formed with a cup shaped or conical enlargement or recess c the
mouths or openings of said nozzles being placed at such a distance from each other
that the jets of water under pressure issuing from them encounter each other and
break up into spray inside this recess c and become mixed and finely divided and
the spray issues from said recess in the shape of a hollow cone corresponding to
the shape of said recess.
In Figs. 1 and 2 a mouthpiece with one pair spray producing and diffusing
nozzles is shewn, the mouthpiece consisting of a pipe n connected to the supply
pipe and divided into two branches leading to the nozzles a b. Fig. 3 shows an
arrangement of a mouthpiece with two pairs of nozzles, the pipe o connected
to the water main dividing into three branches, the central one of which is formed
with a tee piece d at the end into which two nozzles are screwed, as shewn. This
arrangement produces a greater effect than the one shewn by Figs. 1 and 2. for
the same size of supply pipe. Several of such spray diffusers or mouthpieces may
be applied to an air humidifying apparatus. The nozzles may be cleaned after
removal of the screw plugs e.
Fig. 4 shows the application of the improved spray diffusers to an air humidifying
apparatus. Into the casing A a pipe f communicating with the outside is inserted,
in which the diffuser or mouth piece B is fixed in a suitable manner. The casing is
contracted towards the top and carries an adjustable cover plate g and inclined
baffle plates h. The mouth piece k of the casing A is surmounted by a conical
enlargement. The strength of the air current is regulated in the known manner
by adjusting the height of the cover plate g. The water under pressure is supplied
through pipe and the waste water removed through the drain pipe m.
The improved mouthpieces may be arranged in a variety of ways in humidifying
and ventilating apparatus, the one shewn and described with reference to Fig. 4
being only an instance of such application.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.
Firstly in humidifying and ventilating apparatus the use and arrangement of

page_text: spray diffusing mouth pieces connected to the water mains and having one or more
pairs of nozzles, the two nozzles of each pair being placed conaxially opposite
each other and one of them being formed with a cup or conical recess substantially
as herein before described and illustrated by the drawings.
Secondly, the construction of spray producing or diffusing mouthpieces with one
or more pairs of nozzles placed conaxially opposite each other, one of each pair
being formed with a cup or conical recess substantially as hereinbefore described
and illustrated by the drawings.
Dated this 28th day of September 1892.
