IM- PROVEMENTS IN THE TREATMENT OR PREPARATION OF YARNS FOR WEAVING, AND IN MACHINERY OR APPARATUS CONNECTED THEREWITH.
Year: 1870

page_text: LETTERS PATENT to Samuel Howard Stott, of Rochdale, in the
County of Lancaster, Cotton Spinner, for the Invention of "IM-
PROVEMENTS IN THE TREATMENT OR PREPARATION OF YARNS FOR WEAVING,
AND IN MACHINERY OR APPARATUS CONNECTED THEREWITH.'
"
PROVISIONAL SPECIFICATION left by the said Samuel Howard Stott
at the Office of the Commissioners of Patents, with his Petition, on
the 5th March 1870.
I, SAMUEL HOWARD STOTT, of Rochdale, in the County of Lancaster,
Cotton Spinner, do hereby declare the nature of the said Invention for
“IMPROVEMENTS IN THE TREATMENT OR PREPARATION OF YARNS FOR WEAVING, AND
IN MACHINERY OR APPARATUS CONNECTED THEREWITH," to be as follows:-
My Invention consists in imparting to yarns for weaving a certain
amount of moisture after they have been sized and dried by the ordinary
apparatus, and also in conveying to them a second amount of thickening
or a softening matter, such as size, china clay or fatty substances. I
propose to use simple moisture when the yarns have already received a

page_text: heavy sizing, but when such treatment has been comparatively light I
use china clay or other such substance,
To illustrate the method in which my Invention is proposed to be
carried out I will suppose that the yarns have been sized in the machine
known as the "slasher," Upon passing from the steam cylinder they
are separated as usual by the cross rods, and after this pass a revolving
brush placed in connection with a trough, which contains the water,
stiffening or softening matter. The said yarns are then wound upon
the usual drum. In the above-mentioned trough I propose to place a
revolving agitator to keep the solution stirred.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Howard Stott in the Great Seal Patent
Office on the 5th September 1870,
TO ALL TO WHOM THESE PRESENTS SHALL COME, Į, SAMUEL
HOWARD STOTT, of Rochdale, in the County of Lancaster, Cotton
Spinner, send greeting,
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of March, in the year of
our Lord One thousand eight hundred and seventy, in the thirty.
fourth year of Her reign did, for Herself, Her heirs and successors,
give and grant unto me, the said Samuel Howard Stott, Her special
license that I, the said Samuel Howard Stott, my executors, adminis-
trators, and assigns, or such others as I, the said Samuel Howard
Stott, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 In-
vention for "IMPROVEMENTS IN THE TREATMENT OR PREPARATION OF YARNS FOR
WEAVING, AND IN MACHINERY OR APPARATUS CONNECTED THEREWITH,” upon
the condition, amongst others, that I, the said Samuel Howard Stott, by
an instrument in writing under my hand and seal, 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.

page_text: NOW KNOW YE, that I, the said Samuel Howard Stott, 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, and accompanying Drawing, that is to
say:
My Invention consists in imparting to yarns for weaving a certain
amount of moisture after they have been sized and dried by the ordinary
apparatus, and also after such ordinary treatment conveying to them a
second amount of thickening or a softening matter, such as size, china
clay, or fatty substances.
"
The accompanying Drawing represents in section the apparatus I
employ for this purpose. The yarns to be treated according to my Inven-
tion are represented by the blue line proceeding at a from the usual cross
rods, by which they divided divided in the "slasher or other ordinary
machine used in place thereof. These yarns then pass over a roller c
across & trough & over another roller & and from thence are wound upon
the drum e which usually receives them from the "slasher" or other such
machine. The trough 6 is partly filled with the moistening, thickening,
or softening substance, and within it is a revolving brush f mounted in
bearings fixed to the inside of the trough. Beneath this brush is a
revolving agitator g also turning in inside bearings, and the two shafts
are geared together by toothed wheels h, i. As the yarns are drawn
forward by the drum e they pass over the revolving brush f, which
conveys to them a certain amount of moistening, thickening, or softening
matter, and with this second treatment they are wound upon the drum e.
The substance to be placed in the trough 6 will depend upon the nature
and first treatment of the yarns. For fine yarns it may be desirable
to damp them with water only, while for others a mixture of water
and china clay, size, or other usual thickening matters may be
employed. With water only I find that the said yarns are rendered
softer, and are therefore in a better condition for weaving, but with
other such substances as aforesaid added an extra thickening as well as
softening is imparted, and this may also be attained by the use of fatty
matters, which when used I-prefer to place in the trough with water, a
small amount then clings to the brush and effects the desired object.
In order to regulate the quantity of material conveyed to the yarns by the
brushf, the said brush may be caused to revolve by driving it at a suitable
speed, and this driving may be effected by gearing with the wheel h,

page_text: or by any other ordinary convenient means, so that any quantity of
material may be carried up from the trough according to the nature of
the yarns and the effect desired to be produced. I also regulate the
operation by rendering the rollers c, d, capable of adjustment, so that
they may raise and lower the yarns and cause them to bear more or less 5
on the brush f. Whatever substances may be placed in the trough the
revolving agitator g keeps them uniformly mixed.
Having thus described and ascertained the nature of my said Inven-
tion, and the manner in which the same is to be performed, I desire it to
be understood that I claim as secured to me under the above in part 1
récited Letters Patent, imparting moistening, thickening, or softening
matters to yarns for weaving after they have been sized and dried by
ordinary processes, also the apparatus for that purpose substantially as
described.
In witness whereof, I, the said Samuel Howard Stott, have here- 1
unto set my hand and scal, this Thirty-first day of August, in
the year of our Lord One thousand eight hundred and seventy.
