PROVISIONAL SPECIFICATION.
An Improved System for Moistening the Air of Weaving Factories
.
and other Places where a Damp Atmosphere is Necessary.
ROBERT HAMILTON NEILL of Rosebank Weaving Factory Belfast Ireland Merchant
do hereby declare the nature of this invention to be as follows :-
•
In weaving factories for linen and other goods it is often desirable to have a moist
atmosphere to keep the yarn in good working condition. The ordinary method
adopted to obtain this moisture is to blow jets of steam into the room and these are
apt to become hurtful to the workers especially during warin weather.
The object of this invention is to remedy this objectionable practice and to obtain
the required moisture at less expense and at a lower temperature.
This object is attained by this my improved system for moistening the air of weaving
factories and other places where a damp atmosphere is necessary which consists in
collecting the humid air produced by the cooling of the discharge water from the
steam engines and conducting it by means of air propellers and perforated tubes to
those parts of the room where the humid air is required.
By this system of moistening air in manufactories a by-product or waste is employed
for a useful purpose and a better result obtained than heretofore.

COMPLETE SPECIFICATION.
An Improved System for Moistening the Air of Weaving Factories
and other Places where a Damp Atmosphere is Necessary.
ROBERT HAMILTON NKILL of Rosebank Weaving Factory Belfast Ireland Merchant
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:-
In weaving factories for linen and other goods it is often desirable to have a moist
atmosphere to keep the yarn in good working condition the ordinary method adopted
to obtain this moisture is to blow jets of steam into the room and these are apt to
become hurtful to the workers especially during warm weather.
The object of this invention is to remedy this objectionable practice and to obtain
the required moisture at less expense and at a lower temperature.
This object is attained by this my improved system for moistening the air of
weaving factories and other places where a damp atanosphere is necessary which
consists in collecting the humid air produced by the cooling of the discharge water
from the steam engines and conducting it by means of air propellors and perforated
tubes to those parts of the room where the humid air is required.
The means employed for this purpose will be understood from the following descrip-
tion reference being made to the drawing herewith in which the same figures and
letters of reference are used to indicate the same or like parts.
:
Fig. 1 is a section of so much of an ordinary factory for weaving linen goods with
the means employed for moistening the air fully illustrated.
Fig. 2 is a plan view of same.
Figs. 3 and 4 are enlarged views of tubes employed.
To collect the humid air produced by the cooling of the discharge water from
steam engines the ordinary apparatus (a) for breaking up the water into small streams
1
Sa-m
chamber (a) from which the

page_text: saturated or humid air is drawn by a fan (b) or air propeller and conducted thence to
the desired place by means of tubes (d) made of wood or other suitable nonconducting
material for heat in the sides of these tubes (d) openings (d') are made at convenient
distances these openings can be closed at will by sliding doors (d³).
The tubes (d) should have a slight fall from the inlet end so as to discharge any
water that may be caused by condensation-away from the inlet end.
In cases where the condensing water is impure or unsuitable for the purpose of
moistening the air to be used in a work room the air may be saturated by passing
clean water heated slightly so as to give off vapour over the apparatus (a) for breaking
it into small streams as it descends in the collecting chamber (c).
By this system of moistening air by vapour at a low temperature a by product
or waste is employed for a useful purpose and a better result obtained than
heretofore.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
1 claim is,
The combination of apparatus forming the system herein described for moistening
air at a low temperature for weaving factories and other places where a damp
atmosphere is necessary.
