box or chest is partially filled with size, the hanks are placed on pins
fixed in movable cross bars, the cross bars and hanks thereon are then
distended by stretching bars at right angles thereto so as to keep the
hanks of yarn tight on the pins whilst under the process of sizing.
lid or cover is placed on the chest or box, and steam discharged therein
through a pipe for the purpose of boiling the size. The steam box or
chest may be constructed having partitions or separate compartments,
so that yarn of a color may be sized always in one particular com-
partment, and the size becoming colored may be used only for its
corresponding color of yarn. The yarn is after drying removed to the
winding frame, and we prefer to use the cop winding frame" to the
ordinary hank winder," the first-mentioned being readily adapted
to bank winding by placing creels thereon to the cross rails. The
bobbins containing the yarn is now removed to the warping mill, and
in lieu of being beamed on an ordinary yarn beam is wound on what
we term fancy beams"
(the latter beans being used for purposes
herein-after mentioned), these of which two or more are received on
a cross shaft of the warp mill, and motion is imparted to the " fancy
beamis
by the frictional contact of the periphery of pullies fixed on
the cylinder shaft of the mill. The fancy beams are removed from
the shaft of the warping mill to the loom and are there placed upon a
shaft extending across the back of the loom over the ordinary back bearer.
The cross shaft is supported by standards fixed to the side frames of the
loom. Below the fancy beam shaft is a lever with sliding or adjustable
weight, the said shaft and lever are connected by straps. We thus
obtain an independent weighting motion for the fancy beams, the yarn
from which is passed down to and under guides so as to bring it into
the same level or plane as that from the ordinary beam along with
which it is woven.
It will be evident that by the process and apparatus above described
we entirely dispense with the tape sizing machine for sizing the fancy
yarn, and by the apparatus employed for beaming and the apparatus con-
nected with the loom we are enabled to produce pieces or goods having
colored or fancy selvedges or stripes, or in cross or check goods we
can employ various colors, and also that our fancy yarn being separate
and having a distinct weighting motion from that of the ordinary
beam we are enabled to use yarn of any count," vary it ever so much;

consequent on beaming, warping, and sizing with various colored and
counts of yarn as heretofore practised.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Duckworth, William Greenwood, James
Pearson, and John Langtree in the Great Seal Patent Office on the
10th December 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ROBERT
DUCKWORTH, Gentleman, WILLIAM GREENWOOD, Cotton Manufacturer,
JAMES PEARSON, Overlooker, and JOHN LANGTREE, Manager, all of
Blackburn, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of June, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Robert Duckworth, William Greenwood,
James Pearson, and John Langtree, Her special licence that we, the
said Robert Duckworth, William Greenwood, James Pearson, and John
Langtree, our executors, administrators, and assigns, or such others as
we, the said Robert Duckworth, William Greenwood, James Pearson,
and John Langtree, our executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and law-
fully might make, use, exercise, and vend, within the United Kingdom,
of Great Britain and Ireland, the Channel Islands, and Isle of Man,
an Invention for "IMPROVED APPARATUS OR APPLIANCES TO BE EMPLOYED FOR
SIZING AND WARPING YARNB AND FOR WEAVING," upon the condition
(amongst others) that we, the said Robert Duckworth, William Green-
wood, James Pearson, and John Langtree, our executors or adminis-
trators, by an instrument in writing under our, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be performed,
and cause the saine to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.

page_text: NOW KNOW YE, that we, the said Robert Duckworth, William
Greenwood, James Pearson, and John Langtree, do hereby declare the
nature of our said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement:-
"
"
This Invention relates to apparatus for sizing colored or fancy yarn
separate from the general body or plain yarn employed in producing
cloth, and consists in sizing and beaming (by apparatus herein-after
described) such yarn on separate or fancy beams," and in employing
such beams on the loom with a separate or distinct weighting or
letting off" motion from that employed in connection with the yarn
on the ordinary yarn or weavers' beam, whereby we are enabled to
size, beam, and weave yarn of varying counts without the damage
and loss occasioned by unequal strain consequent on use of apparatus
heretofore employed for such purposes.

In the Provisional Specification which we caused to be filed we
describe construction and use of a steam box or chest is partially
filled with size, the hauks are placed on pins fixed in movable cross
bars, the cross bars and hanks thereon are then distended by
stretching bars at right angles thereto so as to keep the hanks of
yarn tight on the pins whilst under the process of sizing. A lid
or cover is placed on the chest or box, and steam discharged therein
through a pipe for the purpose of boiling the size.

The steam box
or chest may be constructed having partitions or separate com-
partments, so that yarn of a color may be sized always in one
particular compartment, and the size becoming colored may be used
I only for its corresponding color of yarn. The yarn is after drying
"removed to the winding frame, and we prefer to use the cop winding
frame to the ordinary hank winder,' the first-mentioned being
readily adapted to hank winding by placing creels thereon to the
cross rails."

Since filing the Specification aforesaid we find such parts not to be of
such utility as at the time of filing the said Provisional Specification
we verily believed them to be, we are therefore desirous of disclaiming,
and do hereby disclaim such part of the Specification aforesaid.
Such being the nature and object of this our said Invention we will
now proceed to describe the same fully, and in order that our Invention

page_text: may be clearly understood we have hereunto annexed a Sheet of Drawings
illustrative thereof, and have marked the same with figures and letters of
reference.
"
The fancy yarn is wound by a winding machine of ordinary con-
struction on bobbins, which are afterwards placed upon a creel similar
to those used with a warping mill, and such yarn is passed through
boiling size and over a steam drying cylinder, and from thence to a
mumber of small beams (herein-before termed fancy beams) placed
on a shaft, similar to that shewn in the Drawings, near the drying
cylinder. This apparatus is similar in construction to an ordinary sizing
machine." The fancy beams are removed from the shaft of the sizing
machine and placed on a cross shaft A (see Drawings, Figure 1 and 2).
At the back of the loom A', A', are fancy beams; the shaft carrying
these is supported by standards or bearings B, B. a, a, are set screws
for securing fancy beams. On the shaft at C is shewn a weight lever,
the cord D from which is passed round the neck of the fancy beam,
and the other end thereof is secured to one of the guides E. These
guides are for the purpose of twining or diverting the yarn from the
beams A to the same line or plane as the yarn from the ordinary
beani F.
ordinary.
The yarn passes on over the back bearer G to the healds as
"
By the use of apparatus above described it will be evident we obviate
the difficulty of sizing yarn of various counts as heretofore practised,
on one general or "weavers' beam and obtain a separate and inde-
pendent weighting motion for the fancy yarn, this enabling us to use
fancy yarn of counts varying from that on the ordinary yarn beam.
without the damage thereto occasioned by unequal strain or tension
thereon, and further, the use of the "fancy beams" in weaving afford
great facility for introducing change of color or pattern in the piece
by changing the fancy beams or by having yarn of varying color wound
on one beam, as shewn at Figure 3.
Having thus fully described and ascertained the nature and particulars
of this our said Invention, together with the manner in which the
same is to be or may be performed, or carried into practical effect,
we would have it distinctly understood that what we qlaim as our
Invention is, the use and employment of the "fancy beams" connected
with the sizing machine in the manner and for the purpose herein
described.

page_text: We also claim the fancy beams applied to the loom together with
the weighting apparatus and guides, in the manner and for the purpose
herein described and illustrated in the Drawings.
In witness whereof, we, the said Robert Duckworth, William
Greenwood, James Pearson, and John Langtree, have hereunto
set our hands and seals, this Eighth day of December, in the
year of our Lord One thousand eight hundred and sixty-nine.
