Year: 1871

page_text: LETTERS PATENT to Thomas Knowles, of Blackburn, in the County
of Lancaster, Cotton Manufacturer, for the Invention of " IMPROVE-
MENTS IN MACHINERY TO BE EMPLOYED FOR SIZING YARN."
Sealed the 26th May 1871, and dated the 4th April 1871.
PROVISIONAL SPECIFICATION left by the said Thomas Knowles at
the Office of the Commissioners of Patents, with his Petition, on the
4th April 1871.
I, THOMAS KNOWLES, of Blackburn, in the County of Lancaster,
Cotton Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MACHINERY TO BE EMPLOYED FOR SIZING YARN," to be as
follows:-
"
This Invention has for its object the construction of such machines so
as to avoid the damage to the yarn nearest the flanges of the unsized
"SOW
yarn beams during its passage from such beams to the " or sizing
box by frictional contact and rubbing against the flanges of the beams,
and to prevent "twirling" and breakage of the yarn by the "opening"
rods after.sizing.

page_text: I employ on such machines a guide or conducting roller attached by
brackets to the lower rail (or other part) of the framework of the
machine in connection with each pair of unsized beams, or a roller may
be used for each beam, the yarn passes from the beam under the guide
or conducting roller to the sow or sizing box direct and independant of
the yarn from the other beams so that rubbing against the flanges of
the corresponding beams and crowding and "twirling" of the yarn is
prevented and moro uniform tension on the whole of the yarn is
secured.
'
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Knowles in the Great Seal Patent Office
on the 19th August 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, THOMAS
KNOWLES, of Blackburn, in the County of Lancaster, Cotton Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of April, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Thomas Knowles, Her special
licence that I, the said Thomas Knowles, my executors, adminis-
trators, and assigns, or such others as I, the said Thomas Knowles, my
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 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 TO BE EMPLOYED FOR SIZING YARN," upon the condition
(amongst others) that I, the said Thomas Knowles, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and scals, 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 Scal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Thomas Knowles, 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 :-
This Invention has for its object the construction of such machines so
as to avoid the damage to the yarn nearest the flanges of the unsized
yarn beam during its passage from such beams to the "sow" or sizing
box by frictional contact and rubbing against the flanges of the beams,
and to prevent "twirling" and breakage of the yarn by the "opening'
rods after sizing.
I employ on such machines a guide or conducting roller attached
by brackets to the lower rail (or other part) of the framework of the
machine in connection with each pair of unsized beams, or a roller
may be used for each beam, the yarn passes from the beam under the
guide or conducting roller to the sow or sizing box direct and inde-
pendent of the yarn from the other beams, so that rubbing against the
flanges of the corresponding beams and crowding and "twirling" of the
yarn is prevented and more uniform tension on the whole of the yarn is
secured.
Such being the nature and object of this our said Invention, we will
now proceed to describe the same in detail, and in order that the same
may be distinctly understood, I have hereunto annexed two Sheets of
Drawings illustrative thercof, and have marked the same with Figures
and letters of reference, the same letter referring to the same part in the
various views or Figures.
Figure 1, Sheet 1, is a side elevation of part of a sizing machine, with
my improvements attached; Figure 2 is a plan view of the same;
Figure 3 (Sheet 2) is sectional elevation shewing beams and guide
roller, and at Figure 4 is detail of fixing or support for guide
rollers.
At A, A, A, is shewn "guide rollers" supported by the brackets B, B, B,
which are secured to the lower rail of frame C of the machine. In the
Drawing one guide roller is shewn in conjunction with each pair of
yarn beams E, E, (yet any number of guide rollers may be employed.)
The yarn F passes from each beam under the guide rollers A, to the sow
or sizing box G direct and independent of the yarn from the beams so
that yarn is prevented rubbing against the flanges of the corresponding

page_text: beams and crowding and "twirling" of the yarn is prevented and more
uniform tension on the whole of the yarn is secured.
Having thus fully described and ascertained the nature and particulars
of this my said Invention, together with the manner in which the
same is to be or may be performed or carried into practical effect, I
would have it distinctly understood that I claim as my Invention the
application, employment, and use of the guide rollers A, in the manner
and for the purpose herein fully described and illustrated in the
Drawings.
In witness whereof, I, the said Thomas Knowles, have here-
unto set my hand and seal, this Fourteenth day of August,
in the year of our Lord One thousand eight hundred and seventy-
one
Witness,
GEO. H. HOLT,
Clerk to Mr. Brierley.
