Improvements in Humidifiers.
I, HORMUSJEB SORABJEE BATLIWALLA, of Humum Street, Bombay, India,
Cotton Manufacturer and Merchant, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement.―
My said invention relates to improvements in humidifiers Its object 18 to
provide a cheap and simple means of moistening or humidifying the air in textile
and other factories without injuring the health of the operatives
This
My said invention consists of an open continuous metallic channel suspended
at a convenient height in the factory and passing round or through it
channel is kept full of water and is inclined so that water will flow through it
and evaporation from its surface will communicate the desired amount of humidity
to the air in the factory The evaporation may be accelerated by means about
to be described
Fig 1 in the accompanying drawing represents in plan the four sides of a
room near to which is suspended by brackets or suspension rods the channel c
fed from the cistern a by means of the pump h The trough o1 channel c is
inclined so that the water shall flow in the direction of the arrows to the cistern a
minus the amount lost by evaporation
An open water gauge of glass is attached to the cistern a as shown at e which
may be graduated in gallons or other measure to indicate the loss by evapora-
tion. A suitable strainer 18 attached at the suction end of the pump to prevent
the passage of fibres or other dirt which may be carried in by the water
In order to increase the rate of evaporation when required light rollers f
covered with felt or other porous substances are suspended at intervals in the
channel as shown in cross section in Fig 2 and in longitudinal section in Fig 3
These rollers f are made to revolve either by direct driving from the nearest
shaft or by the force of the curent in the channel The evaporating surface
may thus be augmented to any requied degree
Evaporation may also be increased by placing a finely perforated steam pipe
at one or more places at the bottom of the channel or at the bottom of the cistern
These will heat the water and promote evaporation
The water supply may if convenient be taken from the overflow of the con-
denser and be allowed to run into the mill tank.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same 18 to be performed I declare that what
I claim 18:-
1 In a humidifier the use of an open suspended inclined continuous channel c
along which water flows by gravity so as to allow of evaporation for the purpose
of humidifying the air of a room substantially as set forth and shown
b
2 A circulating humidifying apparatus consisting of the combination of the
cistern a the pump 6 and the inclined channel c foi returning the water to the
cistern substantially as set forth and shown

page_text: 3 In the channel of a humidifier rollers f covered with porous material which
revolve while suspended in the water either by means of the current or by inde-
pendent driving for increasing the evaporation area substantially as and for
the purpose set forth and shown
4 In a humidifier the use of perforated steam pipes for heating the water to
increase evaporation substantially as set forth and shown
