Year: 1869

page_text: LETTERS PATENT to Robert Caunce, of Mansfield, in the County
of Nottingham, Mill Manager, and Micah Gedling Bradley, and
Bernard Bradley, both of the Town of Nottingham, Cotton Doublers,
for the Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR TWISTING YARNS AND OTHER THREADS OF COTTON, WOOL, SILK, OR OTHER
FIBROUS SUBSTANCES.'
Scaled the 13th August 1869, and dated the 24th June 1869.
COMPLETE SPECIFICATION filed by the said Robert Caunce, Micah
Gedling Bradley, and Bernard Bradley at the Office of the Com-
missioners of Patents, with their Petition and Declaration, on the
24th June 1869, pursuant to the 9th Section of the Patent Law
Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, ROBERT
CAUNCE, of Mansfield, in the County of Nottingham, Mill Manager,
and MICAH GEDLING BRADLEY, and BERNARD BRADLEY, both of the
Town of Nottingham, Cotton Doublers, send greeting.
WHEREAS we are in possession of an Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR TWISTING YARNS AND OTHER THREADS OF COTTON,

page_text: WOOL, SILK, OR OTHER FIBROUS SUBSTANCES,'
," and have petitioned Her
Majesty to grant unto us, our executors, administrators, and assigns,
Her Royal Letters Patent for the same, and have made solemn
Declaration that we really believe ourselves to be the first and truc
Inventors thereof.
NOW KNOW YE, that we, the said Robert Caunce, Micah Gedling
Bradley, and Bernard Bradley, do hereby declare that the following
Complete Specification, under our hands and scals, fully describes and
ascertains the nature of the said Invention, and in what manner the
same is to be performed, in and by the following statement:-
According to the present Invention a tube of metal or other suitablo
substance is fixed in a stationary mail of the machine, called the collar
or bolster rail, such tube passing through a rail moving vertically for
the purpose of raising and lowering the bobbin that the thread may be
wound evenly upon it, the tube being of such a length as to reach nearly
to the top of the blade of the spindle, and of sufficient strength to form
a steady bearing for such spindle, which passes through it. The tube
may form a bearing along its whole length, or may have inserted into
it bushes of metal or other substances to form bearings along any part
of it. The tube forms on its outer surface an axle for the bobbin to
revolve upon, so that the bobbin and spindle are not in contact.
The advantages of this Invention arc,-
First. The steadiness of the spindle in working, on account of its
having a bearing near to the top of it.
Second. The "drag" or tension of the thread in work, being nearly
equal throughout the filling of the bobbin.
And, third. We are enabled to use a much larger bobbin than
usual, when required, with a given strength of spindle.
DESCRIPTION OF THE DRAWINGS ANNEXED.
In Drawing 1, "A, A," represents the tube fixed on the collar or
bolster rail "B," and passing through the moveable rail "C," and
reaching nearly to the top of the spindle; "D" represents the bobbin
resting on the moveable rail "C," with the tube passing through it; and
"E, E," represents the spindle passing through the collar or bolster
rail, the moveable rail, and the tube.

page_text: Drawing 2 represents the tube "C, C," with a method of fastening it
into the collar or bolster rail "B."
Drawing 3 represents the tube "A, A," with the spindle "E, E,"
passing through it, and with bushes or bearings "b, b," for the
spindle.
In witness whereof, we, the said Robert Caunce, Micah Gedling
Bradley, and Bernard Bradley, have hereunto set our hands
and seals, this Eighteenth day of June, in the year of our Lord
One thousand eight hundred and sixty-nine.
