PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Moistening the Air of Weaving
Factories and other Places where a Damp Atmosphere is necessary.
ROBERT HAMILTON NEILL of Rosebank Weaving Fuctory Belfast Ireland,
Merchant do hereby declare the nature of this invention to lie as follows:-
These improvements in apparatus for moistening the air of weaving factories
and other places where a damp atmosphere is necessary relate to the system for
which Letters Patent No. 16423-1888 were granted to the present applicant and
consist in an improved arrangement and simpler form of moistening chamber
wherein a peculiar arrangement of valves for admitting air into the chamber is
adopted and the arrangement of fan or air propellor for drawing the moistened
air from the chamber and forcing it to the distributing tubes.
The moistening chamber is made of wood or iron and made air and water tight
excopt at the orifices for inlet and outlet of water and air.
Water at a suitable temperature is admitted into a trough at the top of the
chamber this trough is perforated on its underside and the water falls like rain to
the bottom of the chamber whence it is pumped up again by a circulating pump.
At.one end of the chamber are a series of valves swinging inwards by which the
amount of air admitted can be controlled.
The opening to the fan is situated as high as convenient so that the air in
passing through the chamber is mado sufficiently humid for the purpose and it
is found that a much smaller chamber is sufficient for this purpose than was
originally employed so that a more compact and convenient arrangement of
chamber is practicable than was formerly used.
By preference a fan with simple square blades is employed as being capable of
developing sufficient pressure to force the air through the distributing tubes.
For convenience of regulating the distribution of the humid air in the room
levers are attached to the sliding doors in the distributing tubes these levers are
so arranged that they can be moved by the attendant without the use of ladders.

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
These improvements in apparatus for moistening the air of weaving factories
aud other places where a damp atmosphere is necessary relate to the system for
which Letters Patent No. 16423-1888 were granted to the present applicant and
consist in an improved arrangement and simpler form of moistening chamber
wherein a peculiar arrangement of valves for admitting air into the chamber is
adopted and the arrangement of fan or air propellor for drawing the moistened
air from the chamber and forcing it to the distributing tubes.
The manner in which these improvements are carried out will be understood
by reference to the accompanying drawing in which the apparatus for moistening
the air is illustrated.
Fig. 1, is a sectional elevation of the chamber with fau and circulating pump
attached and shewn as carried upon brackets attached to a wall.
Fig. 2, is a sectional side view of the chamber, and
Fig. 3, is a plan of the fan.
The arrows on the drawing indicate the direction of the various currents of
air, water, and steam, where the latter is employed.
The moistening chamber (a) is made of wood or iron and made air and water
tight except at the orifices for iulet and outlet of water and air. Water at a
suitable temperature is admitted into a trough (b) at the top of the chamber (a)
this trough (b) is perforated on its underside and the water falls like rain to the
bottom of the chamber (a) whence it is pumped up again by a circulating
pump (c).
Al one side of the chamber (a) are a series of valves (a) swinging inwards and
by which the amount of air admitted can be controlled.
The opening to the fun () is situated as high as convenient so that the air in
passing through the chamber (a) is made sufficiently humid for the purpose and
it is found that a much smaller chamber is sufficient for this purpose than was
originally employed so that a more compact and convenient arrangement of
chamber is practicable than was formerly used.
By preference a fan (d) with simple square blades is employed as being
capable of developing sufficient pressure to force the air through the distributing
tubes.
For convenience of regulating the distribution of the humid air in the room,
levers are attached to the sliding doors in the distributing tubes these levers are
so arranged that they can be moved by the attendant without the use of ladders.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is :-
The apparatus described and illustrated for moistening the air of weaving
factories and other places where a damp atmosphere is necessary.
