IMPROVEMENTS IN FASTENING FLYERS UPON SPINDLES
Year: 1862

page_text: LETTERS PATENT to Richard Stuart and Graham Stuart, Spindle and
Flyer Manufacturers, and Henry Hill, Book-keeper, all of Sheffield, in
the County of York, for the Invention of "IMPROVEMENTS IN FASTENING
FLYERS UPON SPINDLES."
Sealed the 17th October 1862, and dated the 19th April 1862.
PROVISIONAL SPECIFICATION left by the said Richard Stuart, Graham
Stuart, and Henry Hill at the Office of the Commissioners of Patents,.
with their Petition, on the 19th April 1862.
We, RICHARD STUART and GRAHAM STUART, Spindle and Flyer Manu-
facturers, and HENRY HILL, Book-keeper, all of Sheffield, in the County of
York, do hereby declare the nature of the said Invention for "IMPROVEMENTS.
IN FASTENING FLYERS UPON SPINDLES," to be as follows:-
Our Invention consists in forming a deep spiral groove in the top or head
of the spindle, whether the top or head be made tapered or not, and whether
with or without a shoulder, and in fixing inside the tube from which the flyer
legs extend a stud or projection to enter the groove in the spindle top or head..
We sometimes make a different shaped groove, but in all cases of such shape,,
that by being taken into by a pin or stud inside the flyer tube, a sufficiently
secure fastening is made to keep the flyer on the spindle. Again, we some-
times reverse the groove and stud, that is, we make the groove in the flyer

page_text: tube, and form the pin or projection on the spindle top or head. The great
advantages resulting from the means of fastening above described consist in
the facility thereby afforded of "doffing" or taking off and replacing the flyers,
and the time saved as compared with the ordinary means of fastening.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Stuart, Graham Stuart, and Henry Hill in the Great
Seal Patent Office on the 18th October 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, RICHARD
STUART and GRAHAM STUART, Spindle and Flyer Manufacturers, and HENRY
HILL, Book-keeper, all of Sheffield, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of April, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Richard Stuart, Graham Stuart, and Henry Hill, Her special licence, that
we, the said Richard Stuart; Graham Stuart, and Henry Hill; 'our executors,
administrators, and assigns, or such others as we, the said Richard Stuart,
Graham Stuart, and Henry Hill, 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 Man, an Invention
for "IMPROVEMENTS IN FASTENING FLYERS UPON SPINDLES," upon the condition
(amongst others) that we, the said Richard Stuart, Graham Stuart, and Henry
Hill, or one of us, our executors or administrators, by an instrument in writing
under our, or their, or one of our or 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 immediately after the
date of the said Letters Patent.
NOW KNOW YE, that we, the said Richard Stuart, Graham Stuart, and.
Henry Hill, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, reference being had to the Drawings
hereunto annexed, that is to say:-
Our Invention consists in forming a deep spiral groove in the top or head

page_text: of the spindle, whether the top or head be made tapered or not, and whether
with or without a shoulder, and in fixing inside the tube from which the flyer
legs extend a stud or projection to enter the groove in the spindle top or head.
We sometimes make a different shaped groove, but in all cases of such shape,
that by being taken into by a pin or stud inside the flyer tube, a sufficiently
secure fastening is made to keep the flyer on the spindle.
Figure 1 of the accompanying Drawings is a view of a spindle with the top
or head thereof tapered, and with a spiral groove formed therein. Figure 2
is a view of a flyer with the tube in section, fastened upon a spindle. a is the
spiral groove in the spindle, and 6 is the stud in the tube of the flyer. To
secure the flyer to the spindle, place the tube over the tapered head, the stud
6 then enters the groove a, and travels to the end thereof, from which it
cannot be released until the flyer is turned by the hand in a contrary direction
to that in which it and the spindle revolve. Figure 3 is a view of a spindle
in which the top or head is made straight instead of being tapered, and with
a shoulder below for the flyer tube to rest. The flyer is fastened to the spindle
in a similar manner to that before described.
Sometimes we reverse the groove and stud, that is, we make the groove in
the flyer tube, and form the pin or projection on the spindle top or head. The
great advantages arising from the means of fastening above described
consist in the facility thereby afforded of "doffing or taking off and
replacing the flyers, and the time saved in that operation as compared with the
ordinary means of fastening.
And having now described the nature of our said Invention, and in what
manner the same is to be performed, we declare that we claim fastening
flyers upon spindles by means of a single spiral groove and stud as herein-before
described.
In witness whereof, we, the said Richard Stuart, and Graham Stuart,
have hereunto set our hands and seals, this Sixteenth day of October
One thousand eight hundred and sixty-two..
RICHARD STUART. (L.s.)
GRAHAM STUART. (L.S.)
