Improvements in Air-moisteners.
I, ERNST SCHNEIDER, Contractor, of Innere Johannisstrasse, No. 6, Chemnitz,
in the Kingdom of Saxony, do hereby declare the nature of this invention to be
as follows:-
Among the various kinds of air moisteners hitherto known, the best effect and
the finest water spray have been obtained by those in which the water in the
shape of very thin jets is projected against an abutment surface and then broken
up into a fine spray. These appliances, however, have the drawback, that the
fine outlet orifices are soon clogged by the impurities contained in the water.
This has led to the design of air moisteners in which small water jets are
spread out into a water cone, and the latter is directed against a cylindrical abut-
ment or dispersing surface. In this case, however, the water which has not been
broken up into a fine spray will accumulate on the abutment surface, in con-
sequence of which the subsequently arriving particles of water unite more or
less with the water, already on the surface, instead of being further subdivided,
and the efficiency of such apparatus is much reduced.
To avoid this defect, I intercept the cone of water with one or more cylindrical
gratings, which acts as an abutment or dispersing surface for a portion of the conical
water jet, while the remainder passes through the grating and strikes against
a pin cylindrical surface, or against a grate-like surface arranged behind the
grate mentioned above in such a manner that the bars of the second or outer grate
correspond with the interstices of the first or inner grate.
I prefer, to admit the water at high pressure, through a nozzle situated in the
vertical axis of the apparatus, so that the jet strikes downward against convex
or conical surface which spreads the water out into a cone. The conical spray then
meets the cylindrical grating, where a portion is finely dispersed by the bars
of the grating, while the remainder passes between the bars and strikes against
a second grating or against a cylindrical casing co-axial with the surface of the
cylindrical grate.
The conical water jet flowing downward draws air through the upper end of the
cylindrical casing, which air is then charged with fine particles of water, driven
downward, and then gradually deflected sideways by a conoidal or roof shaped core.
The heavy drops of water collect in a basin placed underneath the said core,
and may be drawn off through a small discharge pipe.
The apparatus may be modified by causing the air to flow upward, or by placing
the axis of the apparatus horizontally instead of vertically. The cylindrical grates
may be adjustable in the direction of their axes, in order to disperse the water
more or less, and the sheet metal deflecting core mentioned above may also be
adjustable in the direction of its axis, to regulate the area of the air outlet. In-
stead of discharging the moistened air horizontally all round the cylindrical
casing, it may be directed into diametrically opposite channels, which thus produce

page_text: two horizontal or slightly inclined moist air currents, in which case the deflecting
surface or core must be shaped accordingly.

Improvements in Air-moisteners.
I, ERNST SCHNEIDER, Contractor, of Innere Johannisstrasse, No. 6, Chemnitz,
in the Kingdom of Saxony, 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:-
Among the various kinds of air moisteners hitherto known, the best effect and
the finest spray of water have been obtained by those in which the water in the
shape of very thin jets is projected against an abutment surface and then broken
up into a fine spray. These appliances, however, have the drawback, that the
fine outlet orifices are soon clogged by the impurities contained in the water.
This has led to the design of air moisteners in which small water jets are
spread out into a water cone, and the latter is directed against a cylindrical abut-
ment or
dispersing surface. In this case, however, the water which has not been
broken up into a fine spray will accumulate on the abutment surface, in con-
sequence of which the subsequently arriving particles of water unite more or
less with the water already on the surface, instead of being further subdivided,
and the efficiency of such apparatus is much reduced.
To avoid this defect, I intercept the cone of water with a cylindrical
grating which acts as an abutment or dispersing surface for a portion of the conical
water jet, while the remainder passes through the grating and strikes against
a plain cylindrical surface, or against a grate-like surface arranged behind the
grate mentioned above in such a manner that the bars of the second or outer grate
correspond with the interstices of the first or inner grate.
In the accompanying drawings, Fig. 1 is a vertical section of an air moistener
embodying my invention.
Fig. 3 is one half of a horizontal section of the same and Fig. 2 is a modifica-
tion of Fig. 3, showing an air moistener with two concentric gratings.
Figs. 4 and 5 represent a modification of the lower part of the air moistener
on a larger scale.
The water is admitted at high pressure through a nozzle a situated in the
vertical axis of the apparatus, so that the jet strikes downward against a convex
or conical surface b, which spreads the water out into a conc. The conical spray
then meets the cylindrical grating e, where a portion is finely dispersed by the
bars of the grating, while the remainder passes between the bars and strikes
against a second grating (Fig. 2) or against a cylindrical casing, co-axial with
the surface of the cylindrical grate (Fig. 3).
The conical water jet flowing downward draws air through the upper end of
the cylindrical casing, as indicated by the arrows in Fig. 1, which air is then
charged with fine particles of water, driven downward, and then gradually deflected
sideways by a conoidal base e. The heavy drops of water collect in a conical tray f
placed underneath the said base, and may be drawn off through a central open-
ing g leading to a small discharge pipe not shown in the drawing.
The apparatus may be modified by causing the air to flow upward, or by placing
the axis of the apparatus horizontally, instead of vertically. The cylindrical

page_text: grates may be made adjustable in the direction of their axes, in oiler to more or
less disperse the water, and the sheet metal deflecting base e may also be adjust-
able in the direction of its axis, as indicated by Fig. 4, to regulate the area of
the air outlet. Instead of discharging the moistened air horizontally all round
the cylindrical casing, as in Fig. 1, it may be directed into two diametrically
opposite channels, which thus produce two horisontal or slightly inclined moist air
currents, in which case the deflecting surface or base e and the receiving tray
must be shaped accordingly.
This modification is illustrated by Figs. 4 and 5, where r, represents the
receiving tray. The said tray may be fixed to the outer casing d, as assumed in
Fig. 4, or to a few vertical rails h, extending downward from the baseplate or
frame i, as indicated in Fig. 1.
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:
1. In an air moistener comprising in its construction a device for producing a
conical
spray
of water, a cylindrical abutment or deflecting plate, and one or more
cylindrical grates e adapted to divide and partly disperse the said conical spray
of water before it meets the said abutment or deflecting plate, substantially as
and for the purpose described.
2. An air moistener containing a roof-shaped base or guide plate e adapted to
direct the vertical air current into a pair of approximately horizontal channels r,,
placed diametrically opposite to each other, substantially as described.
3. An air moistener having a roof-shaped and vertically adjustable base or
guide plate e adapted to divert the vertical air current into two diametrically
opposite outlet channels r, r, substantially as described.
