PROVEMENTS IN MACHINERY OR APPARATUS FOR SIZEING AND OTHERWISE
Sealed the 18th December 1852, and dated the 20th October 1852.
PROVISIONAL SPECIFICATION left by the said William Harrison
at the Office of the Commissioners of Patents, with his Petition,
on the 20th October 1852.
I, WILLIAM HARRISON, of Blackburn, in the County of Lancaster,
Machinist, do hereby declare the nature of the said Invention for
" CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SIZEING AND
OTHERWISE PREPARING COTTON, WOOL, FLAX, AND OTHER WARPS FOR
WEAVING," to be as follows, viz. :-
In so arranging & working certain machinery that two or more
warps of yain may be effectually sized, dried, and wound on weavers
beams by one machine at the same operation, whether the yarn upon
cach beam be required of the same or dissimilar "counts," and in the

page_text: manner of marking or dividing cach warp into the same or dissimilar
lengths, and in using one or more "wraiths" for dividing the threads
as they pass through the machine.
These improvements I propose to introduce to the well-known
sizcing machine, described in Specification of Patent granted to
William Henry Hornby and William Kenworthy, both of Blackburn,
manufacturers, for "Certain Improvements in Machinery or Apparatus
for Sizeing and otherwise Preparing Cotton, Wool, Flax, and other
Warps for Weaving," and dated at Westminster the 26th day of
September, A.D. 1839, and as improved by addition of the Invention
of John Harrison, of Blackburn, in the county aforesaid, & described
in Specification of Patent granted to him for "Certain Improvements
in the Manufacture of Textile Fabrics, and in Preparing Yarns &
Threads for Weaving," & dated at Westminster the 27th day of May,
AD 1851
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Harrison in the Great Seal Patent
Office, on the 20th April 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
WILLIAM HARRISON, of Blackburn, in the County of Lancaster,
Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of October, in the

Patent.
NOW KNOW YE, that I, the said William Harrison, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement (that is to say):
.
The nature of my Invention consists in certain improvements upon
machinery or apparatus for sizeing and otherwise preparing threads or
warps for weaving, which is described in the Specification of a Patent
granted to William Henry Hornby and William Kenworthy, both of
Blackburn, in the county of Lancaster, bearing date the Twenty-sixth
September, One thousand eight hundred and thirty-nine, and also in
the Specification of a Patent granted to John Harrison, of Blackburn..
in the county aforesaid, and bearing date the Twenty-seventh day of
May, One thousand eight hundred and fifty-one, which machine or
apparatus is well known, and commonly called the "Tapo Leg" Sizeing
Machine, and upon other machines acting in a similar manner; which
improvements enable me to effectually size, dry, mark, and beam two
warps ready for weaving in one machine at the same time. As my
improvements consist principally in the addition to certain parts of this
description of sizeing machine of duplicates of those parts, I have not
thought it necessary to give detailed Drawings of the machine as
improved by the addition of my Invention, but shall be able to render
myself clearly understood by the assistance of, and by reference to, a
section of certain parts of the machine which is hereunto annexed,
which shews partly a sectional side elevation of the operating parts of
a machine with my improvements added, but divested of all-the details
so as to render it more easily understood.. It will be obvious to those

page_text: acquainted with the principle of the "Tape Leg" Sizeing Machine,
and the mode in which it operates, that within certain limits it is not
a matter of any consequence what number of threads are operated
apon at the same time, as an ordinary machine will as effectually size,
dry, mark, and beam four thousand threads as it will one thousand.
Now, taking advantage of this fact, I put through the macliine a
number of threads equal to two warps, and by providing suitable
apparatus for separating, marking,' and beaming, I am enabled to size
and prepare two warps in the same machine, and at the same time it
will be obvious from the foregoing and from what will herein-after be
explained than more than two warps may be prepared for weaving at
the same time and in the same machine; for instance, such warps that
have only a small number of threads each.
The threads coming
Having now given a general idea of my Invention, I will now pro-
ceed to explain the particular manner in which I carry it into effect.
A, A, A, A, (see the Drawing annexed hereto) represent four warp
beams (though I do not confine myself to that number), upon. which
are wound the threads to be formed into one warp A', A', A', A', are
beams containing the threads for the other warp.
from the beams (A) first referred to are shewn in red; those intended
to form the other warp from the beams A¹, are shewn in the blue lines.
Some of the threads are passed over rollers at B, for the purpose of
keeping them separated; all the threads come together at the comb or
wraith c; they next pass through two sets of healds (el and c), each
warp to its own set of healds; and as in ordinary machines there are
but one set of healds, it is necessary to add another set, with a duplicate
of the apparatus for moving them, &c. After passing through the
healds I place a wood bar D, so as to separate the two warps, and
enable the operator or workman to know in which warp to piece any
thread which may break in coming off the warp beams. After leaving
the bar D, the threads pass over the wood roller E, and comb or wraith
E', and brass roller F, over which they descend into the box G, con-
taining size passing in the size round a fluted roller H, and from thence
between a pair of rollers I, I, which squeeze out the superfluous size;
ánd then to another pair of squeezing rollers J; J; which squeeze

page_text: .
out any remaining superfluous size. After passing through the last:
squeezing rollers J, J, I divide the threads of the two, warps, that is:
separate the two warps by means of a flat rod so that they will not
get "baked" together in passing round the drying cylinders .K,. ',:
the threads being acted upon by the brush K, before arriving at the.
drying cylinder K. 'In coming from the drying cylinders. the warps
pass round the roller L, and then to the roller M, and afterwards. pass
round the roller N, and round another tin roller O, they are here'.
separated, and from thence the lower warp (the red) passes as in the
ordinary machine when sizing one warp to the beam P, passing in its
course over the place of the marker (1), and through the wraith or
comb (2), and over the hollow pipe or shaft 3. The upper warp (the
blue) is (as before named) separated from the lower part at the roller
O, and passes over a marker (1), through a wraith. or comb (2ª), over.
an hollow shaft or pipe (3), and on to a beam (R), all of which, are
duplicate parts of the ordinary machine which have to be added. .
place the beam (R) in a convenient position above the beam (P), and
impart motion to it through a series of toothed wheels from the cones
by a strap (4) and pullies (5, 5), arranging the strap to work over a
friction pulley (6) fixed on the end of a bar (7); and provided with-an
adjusting screw (8), which enables me to put any required degree of
tension on the strap so as to make it adhere more or less to the pulley
(5) driving the beam (R), and thus put the required tension on the
threads in winding upon the beam. It will be clear that any dissimi-
larity in the counts of the yarn or number of threads in the warps will
not be of any consequence, and that the marking of the warps into
cuts or portions of similar or dissimilar lengths may be readily accom-
plished, as the shaft which gives motion to the marker (1) so as to
lift it at the proper time, or when a certain length has passed, requires
only to be continued to the other marker (1"), which will only require
the proper change wheel to make it mark each time that the length
required to be marked off has passed. As the details of the different
apparatus which I have named as the improvements by which my
Invention is carried into effect are well known, and as any ordinary
mechanic would be able to apply them, having the description and

page_text: instructions already herein given before him, I do not consider it neces-
sary to go further into detail.
I have now fully described my Invention, and in what manner it.
may be carried into effect, but do not claim as my Invention any of
the parts separately considered, nor do I confine myself to the details;
but what I claim as my Invention is, the combination of the apparatus
or parts herein-before described to form a machine which will prepare
the threads of two or more warps for weaving at the same time and at
one operation, so long as the peculiar mode of operating is maintained.
In witness whereof, I, the said William Harrison, have here-
unto set my hand and seal, this Nineteenth day of April, One
thousand eight hundred and fifty-three.
WILLIAM HARRISON. (L.S.)
Signed, sealed, and delivered,
being first duly stamped,
in the presence of
