Improvements in Means or Appliances for Ventilating and Supplying
Moistened and Heated or Cooled Air in Weaving and Spinning
Factories and other Enclosures.
I, WILLIAM BRACEWELL of Brinscall, near Chorley in the County of
Lancaster Engineer do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in means or appliances for ventilating and
supplying moistened and heated or cooled air, in such places as weaving and
spinning factories, but is also applicable to other workrooms and buildings.
The object of my invention is to supply an interchange of air, either cooled or
moistened as desired.
In weaving and spinning factories it is very desireable to maintain an uniform
temperature, combined with a proportionate amount of moisture as a means of
assisting in the manipulation of cotton and other goods, and also for ventilating
purposes, for the benefit of the workers employed therein.
To carry out my invention I construct a longitudinal generating chamber of a
large diameter and circular form, in the which a dense and saturated atmosphere is
produced, and made ready for propulsion within a long horizontal tube, placed in
the centre of the shed or building, requireing to be ventilated, and in direct com-
munication with the generating chamber.
At an acute angle from the horizontal tube I carry consecutively other tubes of
a smaller diameter, so as to easily receive the moist or cooled atmosphere, when
passing in a direct current along the main horizontal tube.
One end of the generating chamber is open to the outside atmosphere, so that
the force of the current established in the generating chamber will create an
induced current of fresh air to enter therein.
The propulsion of the current within the generating chamber is established by a
Schield's fan or other pressure blower, having a circular pipe from the blower to
the chamber entrance.
The pipe having an enlarged end with a conical nozzel attached thereto for the
emission of air under pressure.
When a moist atmosphere is required I provide the cularged end of the blower
pipe within the generating chamber, with a conical jet, actuated by steam, so that a
combination of the propelling current from the blower with the jet of steam, is
established before the same is delivered from the conical nozzel of the blower
pipe.
The two being concentric with each other so that if desired, they can be worked
seperately or in combination, for the purpose of inducing a current of air from the
outer atmosphere, and propelling the same within the generating chamber.
The generating chamber is also supplied with a coil of copper pipes, to be either
heated by steam or cooled by water passing through the same as desired, for the
purpose of heating or cooling the air when passing through the chamber.
By this means I claim to heat, cool; or moisten a current of air, intermixed with
fresh atmospheric air, to be used seperately or in combination as desired.

Improvements in Means or Appliances for Ventilating and Supplying
Moistened and Heated or Cooled Air in Weaving and Spinning
Factories and other Enclosures.
1, WILLIAM BRACEWELL of Brinscall near Chorley in the County of
Lancaster 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 improvements in means or appliances for ventilating and
supplying moistened and heated or cooled air, in such places as weaving and
spinning factories and is also applicable for the ventilation of steam ships or
schools or other public buildings, when an interchange of fresh air is required.
The object of my invention is to generate and supply an interchange of air to
the afore mentioned places, provision being made by my arrangement for the air to
be either moistened or heated or cooled as desired.
In spinning and weaving factories it is very desireable to maintain an uniform
temperature, combined with a proportionate amount of moisture, as a means for
assisting in the manipulation of cotton and other goods, it being also requisite that
a system of ventilation should be established for the benefit of the workpeople
employed therein, whereby a free interchange of fresh air can be delivered into the
several workrooms.
The following is a description of this invention in such clear and distinct
language as to enable anyone skilled in the art to which it belongs to put the same
into practice, reference being had to the annexed sheet of drawings which makes a
part of this Specification and to the letters and figures of reference marked thereon,
like figures and letters being used to denote the same and corresponding parts
throughout the drawings.
Figure 1 is a part sectional elevation of this invention, and to carry out the same I
construct a longitudinal generating chamber C, the same being of a large diameter
and circular in form, the inner portion consisting of a porous pipe B, the same
being supported upon hangers "e," and placed concentric with the chamber" C,"
over the porous tube " B," I carry pipes "a," arranged with perforations for
sprinkling the porous tubes B with water, and in connection therewith I form
a perforated metal tube "G," the same being made in two sections, each section
consisting of a bell mouthed tube, the bell mouthed ends being bolted together, so
as to form a larger diameter in the centre of the tube, from pipes "a," a shower of
water (either hot or cold as desired), is made to fall upon the metal tube "G"
thereby distributing itself through the whole area of the tube.
The water from pipes "a," "," being made either hot or cold, so as to regulate
the temperature of the air when passing through the chamber C. by this means a
moistened, cooled or heated atmosphere is made ready for distribution.
The propulsion of the current of air within the generating chamber "C" is
established by a Schield's fan "S," or other pressure blower, having a circular
pipe P, for the conveyance of air from the blower S to the chamber C.
The pipe "P" is constructed with an enlarged end H, having a conical nozzel
attached thereto for the exit of the air when under pressure, the force of the
current from the blower S, being sufficient to establish an induced current of fresh
air from the outer atmosphere along the connecting trunk A, the combination of
the two currents being forced through and around the metal tube G, aud along the
generating chamber C, being thereby moistened cooled or heated, and prepared for
delivery along the tubes D.
All surplus condense water being carried away by tap "b."
In combination with the blower S I arrange trunk R. the same being in direct

page_text: communication with the outer atmosphere so that if desired to be worked alone a
pure atmosphere may be delivered along the tubes D.
When a moistened and heated atmosphere is required, the current of air when
passing along the pipe P from blower S becomes intermixed with steam issuing
from the jet L, being regulated in quantity by the steam tap O.
The jet L is placed concentric with the enlarged end H of blower pipe P so that
if desired the force of steam from the jet L, would if used alone be sufficient to
establish a current of air from the conical end of pipe H and thereby induce a
current of fresh air to enter the pipe A, the whole being propelled along the
pipe D.
Figure 2 describes the arrangement of this invention when used as a means for
the distribution of either moistened or heated or cooled air, within a weaving or
spinning factory.
The central pipe D having branch tubes E, placed at an acute angle from the
main central tube D, so that the conditioned air may have a free circulation within
the whole of the building. Oblong outlets "t being provided for the exit of the
air from each pipe.
"
The whole of the tubes D and E, are placed equidistant betwixt the floor and
the ceiling.
When it is desired to establish an exhaust current, to work in combination with
the propelled currents, I insert fans F along the ceiling, as a means for removing
any foul atmosphere.
Figure 3, describes the arrangement of pipes D when carried around the ceiling
of a room, the pipes D having moulded strips for ornamentation, being provided
with oblong outlets "t" in the pipe for the emission of air within the room the
whole being in combination and connection with generating chamber C and blower
pipe P.
Figure 4 describes the arrangement of this invention when pipes D are carried
along the side walls of schools or other public buildings or steam ships sides, the
whole of the pipes D, when placed in position, being in connection with chamber C
and pipe P, oblong outlets being made in each pipe for the exit of the air.
Fig. 5. shows an elevation of " G," when detached from the tube "C."
Having now fully described the nature of this my invention I wish it to be
understood that what I claim is :-
1. The arrangement, use and application of the method, substantially as herein
described, for the production and propulsion of an heated, cooled, or moistened
atmosphere, to be generated seperately or in combination as desired.
2. For carrying out the method herein before described, the construction and
arrangement of apparatus, substantially as described and illustrated by the accom-
panying drawings.
