PROVISIONAL SPECIFICATION.
Improvements in Air Moistening and Ventilating Apparatus.
We, EUGEN KLEINER, WALTER BOKMAYER & ANTON STEHLIK, all of
Mödling near Vienna, in the Empire of Austria Manufacturers, do hereby
declare the nature of this invention to be as follows :―
This invention consists in various improvements in the usual air-moistening
apparatus, which is combined with a ventilating arrangement, whereby the con-
sumption of water or liquid used in such apparatus is reduced to a minimum and a
powerful conveyance of air in the ventilating space is obtained, and a further object
of the improvement is to cause the air to be perfectly washed and the liquid finely
scattered without the formation of drops.
Our improved air moistening and ventilating apparatus consists of the following
essential parts :-
1. The suction chamber;
2. The moistening appliance;
3. An arrangement by which the suction of the air and its partial moistening
and washing are obtained by two water sprays, working against each other in a
diametrical direction;
4. The appliance of the nozzles or nose-pipes.
The improvements forming the subject matter of this invention are as
follows:-
-
The suction of the air is effected by two nozzles arranged concentrically in
reversed directions in the upper part of the apparatus and under the sprayer and
the spraying ring. The liquid is pressed through the nozzles and, by meeting,
becomes divided in such a way that a hollow cone of water or other liquid is formed
which enters rapidly into the upper part of the case and thus causes a powerful
sucking action.
By these arrangements, a great saving of the liquid, with a powerful conveyance
of air at an equal temperature at any season of the year, is obtained.

COMPLETE SPECIFICATION.
Improvements in Air Moistening and Ventilating Apparatus.
We, EUGEN KLEINER, WALTER BOKMAYER and ANTON STEHLIK all of
Mödling near Vienna, in the Empire of Austria, Manufacturers, 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 consists in various improvements in the usual air-moistening
apparatus (which is combined with a ventilating arrangement) whereby the con-
sumption of water or other liquid used in such apparatus is reduced to a minimum
and a powerful conveyance of air in the ventilating space, or the space to be filled
with moistened air, is obtained, and the liquid is also finely scattered without the
formation of drops in the space in question, and in which the air drawn into the
apparatus is forced to pass through a curtain or cone of water and is thereby not
merely washed but also saturated with moisture.
In order to attain these results in this air-moistening and ventilating apparatus,
we cause two streams of liquid, of preferably different thicknesses (diameters), to
.

page_text: play, under pressure, upon each other in exactly opposite directions for the purpose
of forming a hollow cone of water, whereby the air surrounding the apparatus is
not only powerfully drawn into the same but also a very fine pulverisation, as it
were, of the liquid is produced, and the air drawn in is saturated with the same.
In most of the moistening apparatus hitherto employed, the pulverisation of the
liquid takes place by means of sprayers which are provided with numerous openings,
mostly of the thickness of a hair in size, for the passage of the liquid, which
openings very soon become stopped up by the mineral impurities in the water and
the air, whereby the continuous effective action of the sprayer is considerably
impaired, and, further, these apparatus require constant supervision and cleansing.
The suction and pulverising nozzle employed in this apparatus has only two, and
proportionately large, discharge-openings for the liquid which is to be pulverised,
so that no stoppage can take place, or at least extremely rarely, because the
impurities in the liquid, even if they have not been already retained by the fine
ineshed filter sieve arranged in the supply pipe, can pass freely through the
openings.
By this means, the action of our apparatus remains constant and reliable, even
when working for weeks without any expensive supervision and cleaning, as, in
order to secure a faultless working of our apparatus, it suffices from time to time to
cleanse the filtering sieve box in the supply pipe, which can be done in a few
minutes and with little manipulation.
In order to allow of our invention being better understood, an air moistening and
ventilating apparatus, provided with the above named improvements, will now be
more particularly described, reference being made to the accompanying drawings,
in which :-
Figure 1 shows a vertical section of the apparatus on the line y of
Figure 3.
Figure 2 is a vertical section on the line de of Figure 3; and
Figure 3, a plan of the apparatus.
Figure 4 shows separately, and on a larger scale, the double nozzle employed
for drawing the air (of the room) into the apparatus.
This apparatus consists of preferably a globular case A with a cylindrical
neck, b, which ends in a flat cruciform shaped disc or shell D. This has + radial
discharge passages E for the exit of the mixture of air and moisture from the
apparatus, the spaces between each of the passages E are closed in by means of
plates. In the neck, there is placed a circular piece R with cross bars which
evenly divides the air, saturated with moisture passing, through the apparatus,
and allows the same to deposit, in the form of drops, any excess of moisture.
The point of a distributing cone G extends into the neck b, the base of which cone
lics in the plane of the cover of the shell D. The ends of a stirrup piece B are
bolted or riveted at two opposite points of the neck b, and this piece serves for
attaching the apparatus to the ceiling of the chamber which it is desired to
ventilate.
The case A has at its lower part a cylindrical projection c.
The device for drawing air into the apparatus and for spraying the liquid and
washing and saturating the air thus drawn in with the finely pulverised liquid is
arranged beneath the inserted ring R in a cylinder C penetrating sideways into the
case A.
This device consists of the two nozzles dd, Figure 4 (carried by the one bracket)
of preferably different diameters, to which the liquid is conveyed under pressure by
means of a pipe M, the liquid emerging from the two nozzle orifices in the form of
two jets of different diameters and in exactly opposite directions. Owing to these
jets of liquid acting in opposite directions upon each other, a hollow liquid cone or
curtain (shown in dotted lines in Figure 1) is formed, which vigorously draws the
air surrounding the apparatus into the same through the upper opening in the
cylinder C, which may be adjusted by means of the lid H. The air drawn in is
forced to traverse the cone of liquid on its way through the cylinder C into the

page_text: case A, by which means it is not only washed and freed from all impurities, but, on
its further course through the case A, is also saturated with the pulverised liquid
therein contained, and passes out of the apparatus in the finest subdivision through
the passages E into the chamber which is to be ventilated.
The liquid, on its way to the double nozzle d d', passes first through a filter
box S, Figure 2, placed in the supply tube and provided with a fine sieve.
The liquid which collects in the case A, in the form of drops, passes through a
valve i provided in the bottom plate J into the return pipe N and is thus removed
from the apparatus.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. An air-moistening and ventilating apparatus in which two jets of liquid, of
preferably different thicknesses (diameters), are caused to act upon each other in
opposite directions, so as to draw the surrounding air into the apparatus by means
of the formation of a liquid cone in the direction in which air is intended to
penetrate into the apparatus, and also in order to pulverise the liquid as finely as
possible, substantially as described.
2. An air-moistening and ventilating apparatus in which the air drawn into such
is forced through a liquid cone formed by means of two jets of liquid of preferably
different thicknesses (diameters) playing against one another in exactly opposite
directions, thereby washing the same and saturating it with liquid in a state of fine
subdivision, substantially as described.
3. In an air-moistening and ventilating apparatus, two nozzles d and d' carried
by the one bracket, the mouthpieces of said nozzles being preferably of different
diameters, and standing opposite one another in order to allow jets of liquid under
pressure to play upon one another in diametrically opposite directions for the
purpose of pulverising the liquid and producing a suction cone, substantially as
described and shown.
4. The general arrangement and construction of air-moistening and ventilating
apparatus substantially as hereinbefore described and shown.
