PROVISIONAL SPECIFICATION.
. An Apparatus for Moistening Air.
I, WILLIAM WINSHIP WARDLE, of No. 32, Somerfield Road, Finsbury Park in
the County of Middlesex, Engineer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to simple apparatus for moistening air in factories and other
places where humidity is required.
Through the bottom of a shallow basin or open vessel I pass an air nozzle, or
several such nozzles, each surrounded by a tube which reaches a little above the top
of the nozzle and not quite to the bottom of the vessel, and on this tube I fix a
thimble-shaped piece of muslin or gauze, which may be fine wire gauze. I keep the
vessel charged with water to a level below the top of the air nozzle, and through
the nozzle I send a current of air under moderate pressure. This air current
induces a flow of water up the annular space surrounding the nozzle and breaks up
the water into fine spray which is sent through the meshes of the muslin or gauze,
the heavier drops being arrested and trickling down the muslin to the water in the
vessel.

COMPLETE SPECIFICATION.
An Apparatus for Moistening Air.
1, WILLIAM WINSHIP WARDLE, of No. 32, Somerfield Road, Finsbury Park,
in the County of Middlesex, 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 :-
My invention relates to simple apparatus for moistening air in factories and other
places where humidity is required.
Through the bottom of a shallow basin or open vessel I pass an air nozzle, or
several such nozzles, each surrounded by a tube which reaches a little above the
top of the nozzle and not quite to the bottom of the vessel, and on this tube I fix a
thimble-shaped piece of muslin or gauze, which may be fine wire gauze. I keep the
vessel charged with water to a level below the top of the air nozzle, and through
the nozzle I send a current of air under moderate pressure. This air current induces
a flow of water up the annular space surrounding the nozzle and breaks up the
water into fine spray which is sent through the meshes of the muslin or gauze,
the heavier drops being arrested and trickling down the muslin to the water in the
vessel.
Fig. 1 of the accompanying drawing is a section of air moistening apparatus
according to my
invention;
Figs. 2 and 3 are respectively transverse and longitudinal sections shewing one
form of multiple apparatus.
In all these figures similar letter of, reference are employed to indicate corre-
sponding parts.
A is a pipe or channel supplying air under a moderate pressure to a nozzle N or
to a number of such nozzles, which project above the surface of water W kept in a
basin or vessel B at an approximately constant level. As shewn in Fig. 1, the
nozzle N is surrounded by a tube T which dips into the water W, and which is

page_text: shewn to have a cap C of porous fabric such as muslin or gauze fixed on it. In Figs. 2
and 3 the porous cap C is shewn fixed directly on the nozzle N without tube T.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I claim :-
Apparatus for moistening air consisting of a nozzle standing up in a basin or
body of water with its mouth slightly above the water level, and provided with a
porous cap, so arranged that a current of air passing through the nozzle draws
water up, breaks it into spray and becomes mingled with it, substantially as
described.
