Improvements in Humidifiers.

page_text: We JAMES THOMPSON of Morarji Goculdas Mills, residing at Parel, Bombay,.
India, Mechanical Engineer, and VISHNOO VAMANA SOHONI, of Zaubas Wadi,
Thakurdwar Girgaum, Bombay, India, Mechanical Engineer, do hereby declare
the nature of this invention to be as follows:-
Our said invention relates to improvements in the apparatus known as humidifiers
and used for imparting additional moisture to the air in rooms such as for example
in textile factories.
In its main features our said invention consists of a spray producing apparatus
connected by air and water pipes to a common reservoir from which the water
supply and also the air for the spray apparatus issue at the same pressure. Tho-
air and water may be forced directly into the common reservoir or they may be
first forced into storage reservoirs from which the flow of air and water to the
common reservoir may be controlled by reducing valves, float valves, or other like
means for controlling the working pressure.in the common reservoir.
The spray producing apparatus consists of a chamber surrounding a water nozzle
the orifice of which is cone shaped. The air is admitted to the said chamber which
is closed by a cap containing a cone in line with that of the water nozzle. The air-
and water meet in the cone of the water nozzle and in passing through the cone of
the cap the rush of air breaks up and carries with it the water. On issuing from
the outer cone of the cap the expansion of the air separates the particles of water
and by preventing their coalescence into drops obviates a serious defect to which
some forms of Lumidifiers are liable. As will be well understood such spray
producing devices may discharge directly into the room or into an air supply shaft
as may be most convenient.

Improvements in Humidifiers.
We JAMES THOMPSON of Morarji Goculdas Mills, residing at Parel, Bombay,.
India, Mechanical Engineer, and VISHNOO VAMANA SOHONI, of Zaubas Wadi,
Thakurddwar Girgaum, Bombay, India, Mechanical 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 :-
Our said invention relates to improvements in the apparatus known as humidifiers.
and used for imparting additional moisture to the air in rooms such as for example:
in textile factories.

page_text: In its main features our said invention consists of a spray producing apparatus.
to which air and water are supplied from a common closed roservoir whence they
issue at the same pressure.
The accompanying drawing which is an elevation partly in section is hereinafter
referred to for the purpose of more clearly describing the invention.
K is a closed receptacle or reservoir whence the air and water for the spray
producing apparatus issue. Air is introduced to the reservoir through the pipe K'
either directly from an air compressor or from an air vessel B. In the latter
Arrangement the air may be pumped into the vessel B at a pressure of for example
35 to 40 pounds or more on the square inch. A reducing valve G is interposed
between the air vessel B and the air and water reservoir K for the purpose of
reducing the pressure in the latter to about 15 or 20 pounds per square inch which
we find to be a suitable working pressure. Water is supplied to the reservoir K
from a suitable source having a head or pressure sufficient to feed the water
against the internal pressure in the reservoir K. A ball float valve or other
like device may be used for keeping the height of the water within suitable
limits.
C and D are respectively water and air mains provided with cocks E and F. On
the latter cocks being opened air will flow along the main D while water will pass
through the strainer C and along the main C.
The cocks E and F are connected by branch pipes C' D' (indicated by dotted
lines in the drawing) to the spray producing apparatus.
By the arrangement just described the air and water will reach the spray
producing apparatus at the saine pressure.
n
The spray producing apparatus consists of a casing A which forms a chamber e
round a water nozzle c having a hollow conical outlet. The chamber e is closed by
a cap a baving a conical aperture in line with that of the water nozzle. The air
reaching the chamber e through the air inlet d meets the water in the conical
outlet of the water nozzle and in passing through the coue of the cap the rush of
air breaks up and carries with it the water. As it issues from the conical aperture
of the cap the expansion of the air separates the particles of water and by
preventing their coalescence into drops obviates a serious defect to which some
forms of humidifiers are liable.
Any desired number of spray producing apparatus may be supplied by the
maius CD aud they may be so arranged as to discharge directly into the room or
into an air supply shaft as may be most convenient.
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. In a spray producing apparatus the combination of a water nozzle having a
conical outlet with au outlet for the air and water having a conical aperture in line
with that of the water nozzle substantially as set forth and shown.
2. The combination with a spray producing apparatus of a closed air and water
reservoir communicating there with for obtaining and maintaining an equal pressure
of the air and water substantially as set forth and shown.
3. The combination of the reservoir K the water mains C D the branch
pipes C D the coned water nozzle c the air chamber e and the coned cap a
substantially as and for the purpose set forth and showu.
