Improved Means or Apparatus for Moistening the Atmosphere of
Work-rooms and other like Places.
We NICHOLAS SIIN, Engineer and Sergius JutscHкOW, Merchant both of Tour
Soukharew, Moscow, in the Empire of Russia do hereby declare the nature of our
said Invention to be as follows:-
This Invention relating to means for moistening the atmosphere of work rooms and
other like places consists in improved combinations and arrangements of apparatus as
hereinafter described supplying water in the form of spray in such a manner that the
entering air is effectually moistened and the degree of moisture in the room or other
like place is enabled to he regulated as required.
The introduction of moist air into inhabited places is commonly connected with
the provision for heating and ventilating hut this cannot conveniently be arranged in
practice when it is necessary to maintain a certain regular amount of moisture ir
places such as mills for spinning for example. In the first place the air in the se
places must be moister than in ordinary dwellings; secondly, the moisture requires
to be equally distributed and, thirdly, means must be provided for readily augmenting
or diminishing the amount of moisture in the air or atmosphere of the room in
accordance with the requirements of the work
It is the object of our present invention to provide a pneumatic air moistening
apparatus whereby it is rendered possible to supply any work room or other like
place with an atmosphere moistened in a suitable manner as hereinafter described.
Fresh air taken from outside the building and passed through a series of copper
distributing pipes is supplied in a compressed condition by a compressing apparatus
of any suitable construction driven by steam or other motive power. This compressed
air is conducted to air pipes suspended from the ceilings or otherwise suitably
supported in the rooms being arranged according to the plan of the building. Below
or in proximity to these air pipes there is placed a corresponding series of water
pipes supported by suitable collars and brackets and arranged parallel with the air
pipes. These water pipes are connected with any suitable source of pure filtered
water such as small tanks supplied in turn from a main or central reservoir for
example.
To this system of combined air and water pipes there are attached, at suitable
intervals, according to the requirements of the building pulverisers or spray producers
of any suitable construction which enable the compressed air to inject the water into
the atmosphere of the room in the form of spray. A form of spray producer suitable
for this purpose is constructed with a pipe or nozzle which communicates through an
open tube with the water supply pipe corresponding with each water nozzle there is
an air nozzle communicating with the air supply pipe through a cock.
The air compressing apparatus being set in action the compressed air enters the air
supply pipes and when the air cocks in the spray producers are opened the water is
drawn out of the water nozzle the lower end of which is immersed in the water in
the open tube hereinbefore referred to and is blown off in a fine spray which by its
evaporation rapidly and effectually moistens the air or atmosphere of the room By
augmenting or diminishing the pressure of the air supplied by the compressing
apparatus it is easy to increase or diminish the amount of water or moisture in the
atmosphere and as this pressure depends solely on the speed of the compressing
apparatus it is evident that there is every facility for controlling or regulating the
action of this pneumatic moistening apparatus and maintaining the requisite amount
of moisture in the atmosphere of the rooms.
Regarding the equal distribution of the moisture in the rooms this is obtained

page_text: with facility and effectually, with this pneumatic moistening apparatus by arranging.
any suitable number of the spray producers distributed about the building.
In case it were required to reduce the amount of moisture in any particular part
of the building this can be effected by simply shutting a suitable number of the air
cocks. "To increase the moisture on the other hand in any given place it is merely
necessary to increase the number of spray producers in operation at the corresponding
part of the apparatus.
The pulverisation of the water by means of compressed air is so complete that the
water is evaporated before it has the time to descend to the floor which together with
the machinery is consequently left perfectly dry and clean. At the same time as it
moistens the air the apparatus also contributes to lower the temperature as the
pulverised water or spray absorbs heat in evaporating.

COMPLETE SPECIFICATION.
Improved Means or Apparatus for Moistening the Atmosphere of
Work-roo rs and other like Places.
We NICHOLAS SIMIN, Engineer, and SERGIUS JUTSCHкOW, Merchant, both of Tour
Soukharew, Moscow, in the Empire of Russia, 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 relating to means for moistening the atmosphere of work rooms and
other like places consists of improved combinations and arrangements of apparatus as
hereinafter described for supplying water in the form of spray in such a manner that
the air is effectually moistened and the degree of moisture in the room or other like
place is enabled to be regulated as required.
The maintenance of a sufficiently moist atmosphere in work rooms and other
inhabited spaces frequently requires careful consideration on the part of persons
entrusted with the superintendance of the work or having to look after the accomodation
or dwellings provided for work people.
The introduction of-moist air into inhabited places is commonly connected with the
provision for heating and ventilating but this cannot conveniently be arranged in
practice when it is necessary to maintain a certain regular amount of moisture in
places such as mills for spinning for example. In the first place the air in these
places must be moister than in ordinary dwellings, secondly the moisture requires to
be equally distributed and, thirdly, means must be provided for readily augmenting
or diminishing the amount of moisture in the air or.
r. atmosphere of the room in
accordance with the requirements of the work. The spinning of combed wool for
example is almost impossible without artificially moistening the atmosphere. The
manufacture of spun cotton, especially of the higher numbers of thread is also
attended with much difficulty unless means are provided for artificially moistening
the air.
With the object of moistening the air recourse has been had to a great variety of
contrivances ranging from most simple expedients to highly complicated apparatus.
The simple contrivances are such as sprinkling the floor "with water, supplying water
in open channels or conduits formed in the floor and hanging up wetted cloths or
sheets but all these methods contribute to make the rooms-dirty and are dispensed with
if possible. Other improved but more complicated moistening arrangements exist,
each of which presents advantages combined with certain defects.
Taking into consideration all the disadvantages inherent to the existing methods of
moistening the atmosphere of rooms it is the object of our present. invention to
provide a system which is free from all these defects and by means of the pneumatic
air moistening apparatus herematter described it is rendered possible to provide

page_text: any work room or other like place with an atmosphere moistened to any de-ired
degree.
And in order that our said Invention may be fully understood we shall now proceed
more particularly to describe the same and for that purpose shall refer to the several
figures on the annexed sheet of drawings the same letters of reference indicating
corresponding parts in all the figures.
Figures 1, 2 and 3 of the accompanying drawings illustrate in longitudinal
transverse and horizontal section respectively an example of a mill fitted with
apparatus for moistening the atmosphere according to this invention.
Figures 4 and 5 drawn to a larger scale represent in plan and in elevation
respectively, the elevation being partly in section, the construction of a spray producing
apparatus hereinafter described.
Fresh air taken from outside the building is passed in a compressed condition
through a series of distributing pipes (preferably of copper) by a compressing
apparatus A Figures 1 and 3 of any suitable construction driven by steam or other
motive power. This compressed air is conducted to the air pipes B which are
suspended from the ceilings of the rooms, being arranged according to the plan of the
building. Below or in proximity to these air pipes there is placed a corresponding
series of water pipes supported by collars and brackets and arrange parallel with
the air pipes B as indicated in Figure 4. These water pipes are supplied with
preferably pure filtered water from sinall tanks & Figure 1 supplied in turn from a
main or central reservoir D Figure 1 or other suitable source.
To this system of combined air and water pipes there are attached, at suitable
intervals, according to the requirements of the building, pulverisers or spray producers
of any suitable construction such for example as that illustrated drawn to a larger
scale in Figures 4 and 5 which enables the compressed air to inject the water into the
atmosphere of the room in the form of spray. This spray producer is constructed with
a pipe or nozzle e which communicates through an open tube with the water supply
pipe C as represented in Figure 5.
Corresponding with each water nozzle there is an air nozzle g communicating with
the air supply pipe B through a cock h.
The air compressing apparatus being set in action, the compressed air enters the air
supply pipes B and when the cocks h in the spray producers are opened the water is
drawn out of the water nozzle e the lower end of which is immersed in the
water in the open tube and is blown off in a fine spray which by its evaporation
rapidly and effectually moistens the air. By augmenting or diminishing the
pressure of the air supplied by the compressing apparatus it is easy to increase
or diminish the amount of water or moisture in the atmosphere and as this
pressure depends solely on the speed of the compressing apparatus it is evident
that there is every facility for controlling or regulating the action of this
pneumatic moistening apparatus and maintaining the requisite amount of moisture
in the atmosphere of the rooms.
Regarding the equal distribution of the moisture in the rooms this is obtained with
facility and effectually with this pneumatic moistening apparatus by arranging any
suitable number of the spray producers distributed about the building as in the
example illustrated in Figures 1, 2 and 3.
In case it were required to reduce the amount of moisture in any particular
part of the building this can be effected by simply shutting a suitable number of
the air cocks h.
To increase the moisture on the other hand in any given place it is merely
necessary to increase the number of spray producers in operation at the corresponding
part of the apparatus.
The pulverisation of the water by means of compressed air is so complete that the
water is evaporated before it has the time to descend to the floor which together with
the machinery is consequently left perfectly dry and clean.
This improved system of supplying moist air presents numerous advantages such
for example as the following.

page_text: 1. Simplicity of construction and facility-for-controlling or regulating the action.
2. Absence of any moving parts of mechanism apart from the preparatory air
compressing apparatus.
3. Equal distribution of the moisture throughout the place to be moi-tened.
4. Facility for increasing, reducing and regulating the degree of moisture at will.
At the same time as it muistens the air the apparatus also contributes to lower-the
temperature as the pulverised water or spray-absorbs heat in evaporating, this is of
great importance in spinning rooms When a strong blast or artificial ventilation is
employed with the object of purifying and cooling the atmosphere the quantity of
water supplied must bo increased in proportion.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed, wo declare that what we
claim is :-
1. Moistening the air supplied in work rooms and other places by means of water
conveyed to the sad rooms or places by water pipes and drawn or extracted therefrom
by means of pulverisers or spray producers of any suitable construction by the action of
compressed air delivered through air pipes in such a manner as to reduce the water
to a fine state of division or spray which enters the room or place along with the air
and moistens the atmosphere to the required extent substantially as herein before
described with reference to the accompanying drawings.
2. The general combinations and arrangement of air and water supply pipes and
spray producers constituting the improved means or apparatus for supplying moist
air in work rooms and other like places substantially as herein before described with
reference, to the accompanying drawings.
