Improvements in Apparatus for Supplying Moistened Air to Weaving
Sheds and other Enclosures.
WC, WILLIAM CHRISTOPHER WOOD, of Brinscall Hall, near Chorley, in the
County of Lancaster, Calico Printer, and WILLIAM Bracewell, of Brinscall,
near Chorley, in the County of Lancaster, Engineer, do hereby declare the
nature of this invention to be as follows:-
Now our invention has for its object, the better distribution of .moistened
atmosphere, in weaving sheds and other enclosures, and consists of an improved
arrangement to act in combination with our patented apparatus for which Her
Majesty's Letters Patent were granted to us on the 2nd of March 1887 and
numbered 3208, and our invention consists in causing the atmosphere, which has
been moistened and propelled, by a jet of steam or other elastic fluid under
pressure in our apparatus, as described in the Specification of the Patent herein-
before referred to, to be carried within pipes in any direction or distance as
required.
To carry out our invention, we provide a mixing chamber, the same being in
combination with the distributing plate of our patented apparatus as herein before
referred to.
The mixing chamber being of a circular form, and having upon its outer
periphery four or any other number of branches, so arranged that metal pipes are
connected to the said branches, and thereby the moistened atmosphere is carried in
and to any required distance in the pipes, within the weaving shed or other
enclosure.
The metal distributing pipes being parallel and circular in form, and having
upon their outer periphery oblong apertures, so placed at given distances as to
allow for the exit of the moistened atmosphere.
Each aperture being provided with an adjustable metal slide so that the
admission of the moistened atmosphere can be regulated to. any desired extent,
within the enclosure.
Each branch in connection with the mixing chamber, being provided upon the
upper side with a perforated pipe, so arranged with small holes, that a shower of
water, can fall within the branches, as a means of further cooling the already
moistened atmosphere before passing within and out of the distributing pipes.

Improvements in Apparatus for Supplying Moistened Air to Weaving
Sheds and other Enclosures.
We, WILLIAM CHRISTOPHER Wood, of Brinscall Hall, near Chorley, in the
County of Lancaster, Manufacturer, and 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 par-
ticularly described and ascertained in and by the following statement :—
This invention relates to improvements in the construction and arrangement of
the apparatus for which Letters Patent have been granted to us No. 3208 of 1887
and is designed with the object of providing a better distribution of the moistened
air throughout the weaving shed or other structure in which it is placed.
It consists essentially in the combination with the apparatus described in the
Specification of our former Patent (No. 3208 of 1887) of a closed mixing chamber
provided with one two or more branches to which distributing pipes are con-
nected whereby the moistened air may be carried to any desired part of the
shed or enclosure and of the application thereto of perforated water pipes for the
purpose when required of further cooling the moistened air.
The invention will be fully described with reference to the accompanying
drawings in which the apparatus is shown as applied to a weaving shed and to a
yarn cellar.
Fig. 1, sectional elevation of vertical apparatus.
Fig. 2, sectional plan of same on line a-y.
Fig. 3, sectional elevation of horizontal apparatus.
The apparatus is constructed with a metallic or other outer casing A, prefer-
ably perforated porous perforated pipes B, open at both ends through which the
inlet current of air flows; a compound nozzle C, through which a jet of steam
or air or other fluid under pressure issues, and mixing with the air induces a
current of air through the perforated porous pipes, and in the case of steam or
water also moistens it; and a conical distributing plate D in the way described in
the Specification of our former Patent (No. 3208 of 1887).
Referring more particularly to Figs. 1 and 2.
To the lower or outlet end of the metallic casing A in connection with the
distributing plate D we attach a closed mixing chamber E. The chamber E we
prefer to make of cylindrical form and we attach to its periphery one two or more
preferably four branch pipes F. The branch pipes F have connected to them
distributing pipes G, which extend from the apparatus in any desired direction
and to any distance. By the distributing pipes G the moistened air is carried
from the apparatus to any place throughout the weaving shed or other structure
thus giving it a general action throughout the enclosure instead of merely a
local action at one part thereof. The distributing pipes G are provided at
intervals with apertures g at any given distance apart to allow for the free exit of
the moistened air. The openings g are preferably oblong in shape and are each
covered by a metal or other slide H whereby the admission of the air can be
regulated as desired.
Referring to Fig. 3. the apparatus is here shown horizontal as applied to
yarn cellars the distributing plate of conical shape is dispensed with and the
branch pipe F proceeds from the end of the cylindrical chamber E and is con-
centric therewith and to the end of the branch pipe the distributing pipe G, fitted
with apertures g and slides H, as above described is attached.
In cach of the branch pipes F near the upper side may be placed a per-
forated pipe or pipes I with small holes through which a fine spray or shower of
water may be delivered when it is desired to further cool or moisten the air as it
passes into the pipes for distribution.

page_text: J is the steam pipe which communicates with the compound nozzle C and K is
a waste pipe to carry away any water which may condense and run down in
the interior of the apparatus.
In operation a jet of steam issues through the nozzle C where it is intimately
mixed with the air which passes in through the apertures formed in the sides
of the nozzle C and in addition induces a current of fresh air to enter at the
top and pass down through the porous perforated pipe B. The current of air
thus propelled forward impinges upon the conical distributing plate D in the
chamber E where it is thoroughly intermixed with the steam and all particles
equally moistened thereby. The force of the current of air and the impact
against the sides of the conical distributing plate D (which are preferably flat
opposite the branch pipes F) cause it to flow down the branch pipes F from
which it is distributed as may be required by the distribution pipes G and
apertures g in any part of the enclosure.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we wish it to be
understood that we are aware of the Specification of Letters Patent No. 3265
of 1890 granted to Benjamin Ormerod, John Frost Davies and William
Haythornthwaite, and that we do not claim anything described and claimed therein;
but we declare that what we claim is :-
1. In an apparatus for supplying moistened air to weaving sheds and like.
structures the combination with porous perforated pipes and compound nozzle
through which a jet of steam issues and by which a current of air is moistened
and propelled (as described in Specification of Patent No. 3208 of 1887) of a mixing
chamber E and branch pipes F to which the distributing pipes G are connected
substantially as described.
2. An apparatus for supplying moistened air to weaving sheds and other structures
having the several parts constructed and arranged (with or without the per-
forated water pipes I) substantially as described and shown with reference to-
Figs. 1 and 2.
3. An apparatus for supplying moistened air to structures or enclosures having
the several parts constructed and arranged to operate horizontally substantially as
described and shown with reference to Fig. 3.
