IMPROVEMENTS IN THE PREPARATION OF WEFT YARN TO BE USED IN THE MANUFACTURE OF CARPETS AND OTHER PILE
Year: 1857

page_text: LETTERS PATENT to John Brinton, of Kidderminster, in the County of
Worcester, Carpet Manufacturer, and James Crabtree, of the same Place,
Mechanic, for the Invention of "IMPROVEMENTS IN THE PREPARATION OF
WEFT YARN TO BE USED IN THE MANUFACTURE OF CARPETS AND OTHER PILE
Sealed the 1st June 1858, and dated the 5th December 1857.
PROVISIONAL SPECIFICATION left by the said John Brinton and James
Crabtree at the Office of the Commissioners of Patents, with their
Petition, on the 5th December 1857.
We, JOHN BRINTON, of Kidderminster, in the County of Worcester, Carpet
Manufacturer, and JAMES CRABTREE, of the same Place, Mechanic, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE PRE-
PARATION OF WEPT YARN TO BE USED IN THE MANUFACTURE OF CARPETS AND OTHER
PILE FABRICS," to be as follows:-
Heretofore the general method of treating weft yarn for use in the manu
facture of carpets and other pile fabrics has been to wind the same from the
swifts, first, on to bobbins, and then saturate the same while on the bobbins
in a stiffening preparation or sizing, and when this has been done to wind the
yarn from the bobbins into the required form of cops or pirns. Now, by our
improvements we wind the yarn direct from the swift into a cop or pirn, and.

page_text: in so doing cause it to pass through suitable sizing or other saturating liquid
aided by rollers, by which the yarn becomes moro uniformly saturated before
being formed on to the spools. The trough is provided with a jacket for steam
to keep the saturating liquid hot, and the rollers for conducting the yarn
through the saturating liquid are carried by frames turning on axes and so
arranged that so soon as a yarn breaks, the rollers conducting the same will
immediately rise out of the liquid in order to avoid the necessity for the
operator putting his hands therein. There is also a rubber to prevent too
much liquid being taken by the thread. The details may be varied.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Brinton and James Crabtree in the Great Seal
Patent Office on the 5th June 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
BRINTON, of Kidderminster, in the County of Worcester, Carpet Manufacturer,
and JAMES CRABTREE, of the same Place, Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of December, in the year of our Lord One
thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said John Brinton and James Crabtree, Her special licence that we,
the said John Brinton and James Crabtree, our exécutors, administrators,
and assigns, or such others as we, the said John Brinton and James Crab-
tree, 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 lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Mau, an Invention for "IMPROVEMENTS IN THE PREPARA-
TION OF WEPT YARN TO BE USED IN THE MANUFACTURE OF CARPETS AND OTHER
PILE FABRICS," upon the condition (amongst others) that we, the said John
Brinton and James Crabtree, our exccutors or administrators, by an instrument
in writing under our or their hands and seals, or under the hand and senl
of one of us or them, 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 we, the said John Brinton and James Crabtrec,
do hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to bo particularly described and ascertained
in and by the following statement thereof, that is to say :-
Heretofore, the general method of treating weft yarn for use in the manu-
facture of carpets and other pile fabrics has been to wind the same from the
swifts, first, on to bobbins, and then saturate the same while on the bobbins
in a stiffening preparation or sizeing, and when this has been done to wind
the from the bobbins into the required form of cops or pirns.
yarn
Now, by our improvements we wind the yarn direct from the swift into a
cop or pirn, and in so doing cause it to pass through suitable sizeing or other
saturating liquid aided by rollers, by which the yarn becomes more uniformly
saturated before being formed on to the spools. The trough is provided with
a à jacket for steam to keep the saturating liquid hot, and the rollers for con-
ducting the yarn through the saturating liquid are carried by frames turning.
on axes, and so arranged that so soon as a yarn breaks the rollers conducting
the same can be immediately lifted out of the liquid in order to avoid the
necessity for the operator putting his hands therein. There is also a rubber`
to prevent too much liquid being taken by the thread. The details may be
varied.
But that the nature of these our improvements, and in what manner we
carry the same into effect, may be fully understood, we will proceed to describe
the Drawing annexed.
DESCRIPTION OF THE DRAWING.
The Drawing shows a sectional view, to a reduced scale, of parts of apparatus
for winding yarn on to cops or pirns adapted according to our Invention.
And we would bere state that the arrangements generally of winding machines
being well understood, we have not thought it necessary to show an entiro
machine, but only those modifications which we employ to effect our improve-
ments.
a is the swift from which the yarn is to be drawn. The arms of these
swifts we prefer to make of hoop iron, though they may be made of tin as is
the ordinary practice, and the manner in which they are constructed forms no
part of our Invention. Each yarn as it passes from a swift a, passes up over
a guide b, carried by one end of a lever c, and thence under a roller d im-
mersed in the liquid contained in the trough e, and up over the guide roller f.
carried by the cup or guide g which acts in forming or shaping the cop or
pirn. The lever c turns upon an axis of motion c', and at its other end is

page_text: formed forked, so as to embrace the neck h' of the boss of the pinion h,
which when in contact, with the pinion i, affixed upon the axis i', is capable
of receiving motion therefrom; but when the yarn becomes entangled or
otherwise unduly acted upon, and the tendency is to depress the guide b, the
forked end of the lever c will be elevated, and thereby raise the pinion h from
contact with the pinion i to stop the motion thereof. The boss of the pinion
h carries the spindle j, which passes through and carries round with it the
cop or pirn k. is a bar or rod which is made to rise and fall with the guido
f by being connected to it, and which serves to preserve a uniform tension
upon the thread or yarn during the formation of the cop. The trough e may
be supplied simply with sizeing, or with dyeing, or other liquid, and to prevent
the necessity for putting the hands into this liquid cach roller d is carried
by one end of a lever d', which turns upon the axis c', and at its other end is
formed with a projection d to rest upon that end of the lever c. m is a bar
covered with cloth or other suitable material so placed that the yarn by rubbing
thereon may have the superfluous liquid taken from the trough c, removed
from it. The trough è is capable of being heated by steam applied to the
jacket el. n, n, are parts of the main framing; o are hooks, which, when
required, are capable of taking on to the outer end of the levers c, to hold the
pinions out of gear with the pinions i.
Having thus described our Invention, and the best means we are acquainted
with for carrying the samo into effect, we would have it understood that we
do not confine ourselves to the precise details shown and described, so long as
weft yarn for the manufacture of carpets is conducted direct from the swifts
through suitable saturating liquid to the cops or pirus substantially as
explained.
In witness whereof, we, the said John Brinton and James Crabtree,
have hereunto set our hands and seals, this First day of June in
the
year of our Lord One thousand eight hundred and fifty-eight.
