CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR POLISHING AND FINISHING YARNS OR THREADS
Year: 1856

page_text: LETTERS PATENT to William IIunt, of Tonge, near Middleton, in the
County of Lancaster, Silk Manufacturer, for the Invention of "CERTAIN
IMPROVEMENTS IN MACHINERY OR APPARATUS FOR POLISHING AND FINISHING
YARNS OR THREADS."
Sealed the 16th December 1856, and dated the 19th June 1856.
PROVISIONAL SPECIFICATION left by the said William Hunt at the
Office of the Commissioners of Patents, with his Petition, on the 19th
June 1856.
I, WILLIAM HUNT, of Tonge, near Middleton, in the County of Lancaster,
Silk Manufacturer, do hereby declare the nature of my said Invention for
"CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR POLISHING AND
FINISHING YARNS OR THREADS," to be as follows:-
These improvements apply to a certain novel arrangement of mechanism
for polishing and finishing yarn, threads, &c. in the hank; and consist in
passing the yarn or thread, when in a wet or previously sized state, over and
around a suitable arrangement of revolving rollers, stationary rods or beams,
and steam chests or tanks. The stationary rods or beams are covered with
cloth, felt, or other soft substance, which lays the fibres of the yarn or thread
as it passes over the cloth, &c. The bank of yarn is (simultaneously with

page_text: the laying of the fibre) dried and polished by passing over the revolving
rollers and steam chests. This apparatus is so arranged, that the inside and
outside surfaces of the thread are alike polished and finished by passing over
the combination of rollers, covered rods, and steam chests.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Hunt in the Great Seal Patent Office on the
19th December 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HUNT, of Tonge, near Middleton, in the County of Lancaster, Silk Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of June, in the year of our Lord
One thousand eight hundred and fifty-six, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Hunt, Her especial licence that I, the said William Hunt, my
executors, administrators, and assigns, or such others as I, the said William
Hunt, 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 "CERTAIN IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR POLISHING AND FINISHING YARNS OR THREADS,"
upon the condition, amongst others, that I, the said William Hunt, 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
Offico within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said William IIunt, 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 Drawings (that is to say) :-
These improvements apply to a certain novel arrangement of mechanism
for polishing and finishing yarns, threads, &c. in the hank; and consists in

page_text: passing the yarn or thread, when in a wet or previously sized state, over and
around a suitable arrangement of revolving rollers, stationary rods or beams,
and steam chests or tanks. The stationary rods or beams are covered with
cloth, or felt, or other soft substance, which lays the fibres of the yarn or
thread as it passes over the cloth, felt, &c. The hank of yarn is (simul-
taneously with the laying of the fibre) dried and polished by passing over
the revolving rollers and steam chests. This apparatus is so arranged, that
the inside and outside surfaces of the thread are alike polished and finished
by passing over the combination of rollers, covered rods, and steam chests.
In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawings, made upon a scale of
about one inch and a half to a foot, and having similar letters of reference
inarked upon corresponding parts of the mechanism throughout all the Figures
shewn.
Fig. 1 is a sectional elevation of the apparatus employed for polishing and
finishing yarns or threads; Fig. 2 is a front elevation, shewing the method
of supporting the felt, cloth, &c., and the yarn passing over the same; Fig. 3
is an end view, shewing the position of the rollers and heated cylinders,
which are so arranged that both the inside and outside surfaces of the hank
of yarn may be equally well finished; Fig. 4 is a sectional view of the bars
or rods, covered with cloth, felt, or other soft substance, shewn about half the
real size, and in their relative position to the rollers.
In Fig. 1, a, a, are the driving rollers, over and around which the hanks
of yarn or thread & pass; c, c, are the heated chests or cylinders, upon which
are placed the stationary rods or bars d, d, covered with felt, cloth, &c.
It will be seen, upon reference to the Drawings, that the Invention is applied
to a polishing and finishing machine. The bank of yarn being placed upon the
outer surfaces of the driving rollers, and at any portion of its endless length,
it presses against the stationary cloth or felt bar d, and upon the heated
cylinder c, as it passes downwards; by this means the inside surfaces of the
hank of yarn is polished; and when passing upwards, it presses upon similar
stationary felt bars and heated cylinders, and thus the outer surfaces of the
threads become similarly polished and finished.
Having now described the nature and object of my said Invention, together
with the manner of performing the same, I would remark, in conclusion,
that I claim the novel application, employment, and use of stationary bars or
rods, covered with felt, cloth, flannel, or other soft substance, to be placed
upon the heated cylinders, so as to polish and dry the thread on both sides

page_text: as it passes around the distending rollers. Without wishing to confine myself
to the application of the covered bars or rods, the exact description of
machinery herein shown as my Invention is equally applicable to other kinds
of machinery for finishing and polishing yarns or threads in the hank.
In witness whereof, I, the said William Hunt, have hereunto set my
hand and seal, this Eighteenth day of December, in the year of our
Lord One thousand eight hundred and fifty-six.
Signed, scaled, and delivered by the said
William Hunt, in the presence of
LEWIS CLEM, BIRCH.
WILLIAM HUNT. (L.S.)
