Simpson, and Frederic Simpson, all of Preston, in the County of
Lancaster, Cotton Spinners and Manufacturers, for the Invention.
of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SIZING AND DRYING
YARNS FOR WEAVING."
Sealed the 2nd February 1869, and dated the 17th August 1868.
PROVISIONAL SPECIFICATION left by the said Charles John Simpson,
Walter Simpson, Arthur Simpson, and Frederic Simpson at the
Office of the Commissioners of Patents, with their Petition, on the
17th August 1868.
We, CHARLES JOHN SIMPSON, WALTER SIMPSON, ARTHUR SIMPSON,
and FREDERIC SIMPSON, all of Preston, in the County of Lancaster,
Cotton Spinners and Manufacturers, do hereby declare the nature of
our said Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
SIZING AND DRYING YARNS FOR WEAVING," to be as follows:-
This Invention relates to a novel combination and arrangement of
apparatus for. sizing and drying yarns for weaving, whereby the yarn

page_text: is better sized and is stronger than when sized with an equal quantity
of sizing used in the ordinary machines.
According to our Invention we employ one or two size troughs or
boxes, and place one of the two drying cylinders at present in use,
or an extra drying cylinder, above or between such trough or troughs,
so that the yarn after it leaves the trough or first trough may be
dried or partially dried by passing round the first drying cylinder
before it enters the trough again, or the second trough where it
receives an additional coat of size. From this second trough, or after
the yarn has passed through the trough the second time, the yarn
passes round the second drying cylinder situate at the end of the
machine, and on leaving this cylinder it is guided by means of guide
rollers over a revolving fan which greatly assists the drying process.
A presser or cleaner is caused to bear against the surface of the
first drying cylinder by the aid of a spring or otherwise in order to
maintain the surface of such cylinder perfectly clean.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles John Simpson, Walter Simpson, Arthur
Simpson, and Frederic Simpson in the Great Seal Patent Office on
the 16th February 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHARLES
JOHN SIMPSON, WALTER SIMPSON, ARTHUR SIMPSON, and FREDERIC
SIMPSON, all of Preston, in the County of Lancaster, Cotton Spinners
and Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of August, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Charles John Simpson, Walter
Simpson, Arthur Simpson, and Frederic Simpson, Her special license
that we, the said Charles John Simpson, Walter Simpson, Arthur
Simpson, and Frederic Simpson, our executors, administrators, and
assigns, or such others as we, the said Charles John Simpson, Walter
Simpson, Arthur Simpson, and Frederic Simpson, our executors, adminis-

page_text: trators; or 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 lawfully 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 "IMPROVEMENTS IN MACHINERY
OB APPARATUS FOR SIZING AND DRYING YARNS FOR WEAVING," upon the con-
dition (amongst others) that we, the said Charles John Simpson, Walter
Simpson, Arthur Simpson, and Frederic Simpson, our executors or
administrators, by an instrument in writing under our hands and
seals, or under the hand and seal of one of us, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Charles John Simpson, Walter
Simpson, Arthur Simpson, and Frederic Simpson, 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, reference being had to the accompanying
Drawings, and to the letters and figures marked thereon, that is to
say:-
Our said Invention relates to a novel combination and arrangement
of apparatus for sizing and drying yarns for weaving, whereby the yarn
is better sized and is stronger and smoother than when sized with an
equal quantity of sizing used in the ordinary machines, as the size is
thinner and strikes more into the core of the thread.
According to our Invention we employ one, two, or more size troughs
or boxes, and place one of the two drying cylinders at present in use,
or an extra drying cylinder, either above, or below, or between such
trough or troughs, so that the yarn after it leaves the trough or first
trough may be dried or partially dried by passing round the first drying
cylinder before it enters the trough again, or the second trough where it
receives an additional coat of size. From this second trough, or after the
yarn has passed through the trough the second time, the yarn passes
round the second drying cylinder situate at the end of the machine, and
on leaving this cylinder it is guided by means of guide rollers over a
revolving fan which greatly assists the drying process.
And in order that our said Invention may be fully understood we

page_text: shall refer to the Drawing annexed, which represents so much of a
yarn sizing and dressing machine as is sufficient to illustrate our said
Invention.
A is a portion of the main framing of the machine; B, one of the yarn
beams or rollers; C, the size trough which may be of the usual con-
struction. The warp or yarn a (indicated by a blue line in the Drawing)
after leaving the beams A is guided by one or more guide rollers D, D,
to the edge of the size trough into which it dips, the yarn being made to
pass under the immersing roller E, which may or may not be adjustable
in height as found desirable. As the under side of this roller is immersed
in the size it follows that the yarn takes up a certain amount of such
size, and as the yarn leaves the trough the superfluous size is squeezed
from it by causing the yarn to pass between the pair of squeezing
rollers F, F. From these rollers the yarn passes in the direction
indicated by the arrow round the drying cylinder G, whereby it is
dried preparatory to its receiving a second coating of size, whether such
second coating be effected by a second actual immersion in the trough
itself by passing under a second submerged or partially submerged
immersing roller like the first one E, or by simply passing between the
second pair of squeezing rollers F, F, the lower roller revolving in the
size and taking up sufficient thereof to coat the surface of the yarn as
it passes between the two rollers. After receiving its second coating
of size the yarn passes direct to the ordinary drying cylinder G³, on
leaving which it may or may not be subjected as found desirable to a
cooling current of air generated by the fan H; any convenient arrange-
ment of guide rollers I, I, may be adopted for directing the course of
the yarn after it leaves the second drying cylinder G¹.
It is immaterial to our Invention whether the yarn receives its full
supply of size from one and the same size trough as shown in our
Drawings, or from two separate and distinct troughs, provided always
that the yarn undergoes a drying process between the first and second
applications of the size thereto. The lower one of the two pairs of
squeezing rollers F and F derive each a uniform positive rotatory motion
from the bevil or other gearing K, K', as is well understood by those
conversant with this class of machinery, care being taken not to put any
unnecessary or unequal strain or tension upon the yarn. After leaving
the last one of the drying cylinders the yarn is received on to bcams
in the usual manner.
warp

page_text: It will be obvious that this construction of apparatus may also be
adapted for using (after the first sizing and drying) a different quality of
size or a lubricating material, such, for example, as grease of any kind,
which might be applied after the first sizing and drying process instead
of a second coating of size.
Having now described and particularly ascertained the nature of our
said Invention, and the manner in which the same is or may be used or
carried into effect, we would observe in conclusion that what we consider
to be novel and original, and therefore claim as the Invention secured
to us by the herein-before in part recited Letters Patent is, the con-
struction and use of machines for sizing and drying yarns or warps,
wherein the yarns or warps are subjected to two distinct sizing operations,
and are dried or partially dried between such sizing operations by passing
round an intermediate drying cylinder or its equivalent, substantially as
herein-before described.
In witness whereof, we, the said Charles John Simpson, Walter
Simpson, and Frederic Simpson, on behalf of ourselves and the
said Arthur Simpson, have to this our Specification set our hands
and seals, the Twelfth day of February, One thousand eight
hundred and sixty-nine.
