IMPROVEMENTS IN THE AUTOMATIC ELEVATION OF TEXTILE MATTERS IN REVOLVING COILERS OF SPINNING MACHINES
Year: 1871

page_text: LETTERS PATENT to Ernest Bazin, of No. 73, Rue Taitbout, Paris,
Civil Engineer, for the Invention of "IMPROVEMENTS IN THE AUTOMATIC
ELEVATION OF TEXTILE MATTERS IN REVOLVING COILERS OF SPINNING
MACHINES."
Scaled the 22nd December 1871, and dated the 26th June 1871.
PROVISIONAL SPECIFICATION left by the said Ernest Bazin at the
Office of the Commissioners of Patents, with his Petition, on the
26th June 1871.
I, ERNEST BAZIN, of No. 73, Ruo Taitbout, Paris, Civil Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE AUTOMATIC ELEVATION OF TEXTILE MATTERS IN REVOLVING COILERS OF
SPINNING MACHINES," to be as follows :—
One of the chief drawbacks to the employment of revolving coilers in
spinning machines has been the action of the centrifugal force common
to all bodies gifted with a quick rotary motion, causing an inevitable

page_text: breakage of the thread stored in the coiler, which occurs as the coiler
empties itself on account of the increasing length of the thread.
The object of this Invention is to obviate this defect, which may be
effected in two ways :—
1st. By annulling the effect of the centrifugal force on the thread.
The coiler which consists of two cylinders one within the other, the
inner one being pierced with holes for the passage of impurities, has
the thread wound round a solid or hollow central shaft fixed to the
stationary bottom of the coiler in eccentric circles. The automatic
rising of the movable plate or bottom is caused by a spiral spring.
beneath it, whose fulcrum is the solid or immovable bottom of the
coiler, so that as the thread is payed out the bottom rises maintaining
a regular equidistant delivery from the head or cover of the coiler.
2ndly. By utilizing the centrifugal force for raising the movable
bottom by aid of a jointed lever similar in form to the lazy-tongs,
connected in the centre by sockets capable of moving up and down the
central shaft in the interior of the coiler. To the lower socket is articu-
lated a double elbow lever, to each end of which a counterpoise is
attached of sufficient weight to admit of the development of the levers
increasing by aid of the centrifugal force as the coiler empties.
The Invention therefor consists in raising the thread automatically
either by means of a spiral spring [the thread passing round the
internal central shaft of the coiler in eccentric circles] and annulling
the centrifugal force. Or by utilizing it by aid of the jointed lever
and counterbalances for raising the movable bottom of the coiler as
before described.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Ernest Bazin in the Great Seal Patent Office
on the 23rd December 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ERNEST 30
BAZIN, of No. 78, Rue Taitbout, Paris, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of June, in the year

page_text: 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 Ernest Bazin, Her special licence that
I; the said Ernest Bazin, my executors, administrators, and assigns, or
5 such others as I, the said Ernest Bazin, 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 THE AUTOMATIC
ELEVATION OF TEXTILE MATTERS IN REVOLVING COILERS OF SPINNING MACHINES,"
upon the condition (amongst others) that I, the said Ernest Bazin,
my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Ernest Bazin, 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 :—
One of the chief drawbacks to the employment of revolving coilers in
spinning machines has been the action of the centrifugal force common
to all bodies gifted with a quick rotary motion, causing an inevitable
breakage of the thread stored in the coiler, which occurs as the coiler
empties itself on account of the increasing length of the thread.
My improvements remedy this evil, and henceforth render the em-
ployment of revolving coilers not only practicable and useful but
constitute a real progress in spinning hemp, flax, and all textile matters
in general.
I attain this result in two ways, first, in combating and annulling the
dangers of the centrifugal force, and secondly by employing the force
for effecting the automatic ascension of the textile matter, which latter
is in both cases always paid out at the same height whether the coiler
is completely or partially charged.

page_text: plate bearing the textile matters in the two manners already described,
that is to say, either by the suppression of the centrifugal force or
by its utilization in the manner and for the purposes herein described
and illustrated in the accompanying Drawings.
In witness whereof, I, the said Ernest Bazin, have hereunto set
my hand and seal, this Eighteenth day of December, in the
year of our Lord One thousand eight hundred and seventy-one.
