I, GEORGES DELERART, of 60, Rue du Long Pot, Fives Lille (Nord), France,
Cotton Spinner, do hereby declare the nature of this invention to be as follow
This invention relates to apparatus for moistening au in apartments especially
those of factories in which operations on textile materials are carried on.
The apparatus comprises a fan or blower by which a curient of air is directe.
horizontally along the surface of water which may, when requned, be heated and
which preferably is the distilled water resulting from the condensation of steam
employed for the heating The water is contained in a shallow trough and the
air may be blown along it either from one end of the trough or in both directions
trom the middle of the trough, which is preferably situated at one side of the
apartment Along the opposite side of the apartment is arranged an an conduur,
having openings provided with valves at intervals along it. This conduit 18 con-
nected to the suction of the fan or blower so that air is drawn from the apartment
through the valved openings in quantities of each which can be regulated as
desired The conduit also communicates with the outer air by a passage governel
by a valve, so that, when desired, air can be drawn in from the outside to supply
the fan or blower
When it 18 desirable to increase the surface for moistening the an, I employ a
hollow cylinder open at each end and partly immersed in the water of the trough
in which it is caused to revolve so that its outer and inner surfaces are always wet
The air passing along these surfaces as well as that of the water in the trough
takes up moisture to an amount depending on the temperature and the extent of
the wet surface thus exposed to the air current
Several cylinders may be employed in this manner. Instead of a cylinder an
endless apron of suitable porous fabric may pass 1ound a pair of revolving rollers
partly immersed in the water so as to be kept constantly moistened, while the air
is blown along the moistened surfaces
Otherwise a stationary porous fabric may be arranged on a framing somewhat
like a roof, the edges of the fabric dipping in water so that the tabine becomes
moistened by capillary attraction, and gives off moisture to the air which is blown
along its inner and outer surfaces
The conduit having valved openings may be dispensed with, fresh air drawn
from the atmosphere being blown upon the water in the trough or along the
moistened surfaces
Air moistened in the manner described is especially applicable for conditioning
cotton yarn particularly after its treatment with steain as described in the
Specification No 18,347 of 1897

page_text: 1, GEORGES DELERART, of 60, Rue du Long Pot, Fives Lille, (Nord), France,
Cotton Spinner, 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 moistening air in apartments, especially
those of factores in which operations on textile materials are carried on.
Hitherto air has been moistened by evaporation of water, or by putting water in
rapid movement and blowing in the water particles By the former process no
uniform moistening throughout the apartment can be effected, as the layers of moist
an over the water surface become only very slowly diffused. When the latter process
18 employed, some portions of the atmosphere are too moist while others are not
moistened at all.
These objections are obviated by the present invention, according to which
differences of piessuie can be produced as desired at different places so as to diffuse
the moisture uniformly, as will be described with reference to the accompanying
diawings.
Fig 1 a plan of an apartment in which the apparatus is fitted. Fig 2 is a
longitudinal section drawn to an enlarged scale of the moistening appliance.
R is a long shallow tough in which water is maintained at constant level. The
water is warmed by steam passed in regular quantity through a pipe r. The
water of condensation is passed through a steam trap E and into the trough which
thus always receives a supply of distilled water
U is a centrifugal fan, having its suction connected by a pipe T with a pipe A,
which can have valves opened at various places a along its length The moisten-
ng appliance R 18 most advantageously situated at the wall opposite to A. The
an diawn in through the pipes A and T is sent by a pipe T into a distributor S
placed above the water trough at about the middle of its length.
From S two branches e terminating in flat horizontal nozzles discharge the air just
over the surface of the water, along which the air is caused to flow horizontally by
extensions d of the upper sides of the branches c.
The pipe A which extends the whole width of the apartment besides having the
valved openings a has also a valved opening X to the outer air, by which more or
less air can be drawn in, along with that drawn from the apartment
The moistening appliance R may be situated at any place in the apartment, but
the situation of the exhaust pipe depends on that of the trough.
When the fan 18 worked the air discharged flows over the surface of the warmed
water in the trough R, and being charged with moisture is diffused through the
apartment towards the pipe A where the pressure is somewhat reduced.
As this reduction of pressure can be caused at various places by opening more or
less some of the valves a, the streams of moistened air can be so directed as to give
uniform moistening throughout the apartment
The supply of distilled water to the trough R prevents the calcareous deposit
which would result from the use of undistilled water. As more distilled water is
always supplied than is evaporated, the trough R is provided with an overflow the
level of the water being therefore maintained constant so as just to touch the lower
edges of the air outflow branches c
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is: :-
Apparatus for uniformly moistening air in an apartment, comprising a fan, its

page_text: suction and discharge pipes so arranged that the air delivered by the fan is caused
to flow along the surface of water automatically supplied by condensation of steam
that heats it, and that by adjustment of openings to the suction pipe A. the
moistened air is 80 diffused that the air throughout the apartment 18 uniformly
moistened.
