IMPROVE- MENTS IN SPINNING
Year: 1877

page_text: LETTERS PATENT to Joseph Bottomley, of Buttershaw, near Bradford, in the
County of York, Spinner and Manufacturer, for the Invention of "IMPROVE-
MENTS IN SPINNING."
Sealed the 27th October 1877, and dated the 14th August 1877.
PROVISIONAL SPECIFICATION left by the said Joseph Bottomley at the
Office of the Commissioners of Patents on the 14th August 1877.
JOSEPH BOTTOMLEY, of Buttershaw, near Bradford, in the County of York,
Spinner and Manufacturer. "IMPROVEMENTS IN SPINNING."
The object of this Invention is to prevent the strong hairs or "kemps" in mohair
or other yarns becoming entangled with the spun thread during the process of
spinning, thus producing a smoother yarn; and further, to prevent such strong hairs
or kemps getting under the bottom of the bobbins or spools upon which the fabric
is being spun, and thereby preventing the detrimental interference with the drag.
accomplish the above object in the following manner :-I form in the bobbin
upon which the yarn is to be spun two recesses, one in the top flange on the under
side, the other on the bottom flange on the top side, and in the spool for weaving a
recess is formed on the top side of the bottom and only flange.
I claim the recessing or the formation of a recess in the flanges of bobbins, top or
bottom, and of the bottom of spools, substantially in the manner herein described.

JOSEPH BOTTOMLEY, of Buttershaw, near Bradford, in the County of York,
Spinner and Manufacturer. "IMPROVEMENTS IN SPINNING."
The object of this Invention is to prevent the strong hairs or "kemps" in mohair
or other yarns becoming entangled with the spun thread during the process of
spinning, thus producing a smoother yarn; and further, to prevent such strong
hairs or kemps getting under the bottom of the bobbins upon which the fibre is
being spun, and thereby preventing the detrimental interference with the drag.
I accomplish the above object in the following manner:-I form in the bobbin
upon which the yarn is to be spun two recesses, one in the top flange on the under
side, the other on the bottom flange on the top side. The lifter I make to traverse
the thread into these recesses.
I claim the recessing or the formation of a recess in the flanges of bobbins, top
or bottom, used in the spinning of all fibrous substances, substantially in the manner
herein described.
In order to enable my improvements to be more readily understood I will proceed
to describe the accompanying Drawings, in which,―
T
Figure 1 represents an elevation of such portions of a spinning frame, as are
sufficient to illustrate my Invention.
1
Figure 2 shews the bobbin hitherto in use compared with my improved bobbin
when full.
A is the ordinary bobbin empty; B is the ordinary bobbin full, shewing the long
hairs or "kemps" near to the top and bottom flanges. On reference to Figure 2 it
will be readily understood that the long hairs underneath the top flange lash the
down thread x which is being spun, constantly breaking down the thread, and
when not breaking it down making it rougher, or causing the same to snarl, it
thereby deliteriously affecting the regularity of thickness and strength of the
yarn.
The long hairs on the bottom of the bobbin wrap round the revolving spindle and
detrimentally affect the drag. So far I have described the ordinary bobbin' in
common use with a view to shew its disadvantages.
C shews my improved bobbin with the recesses in the top and bottom flanges;
D shews my improved bobbin full, without the long hairs at the top and bottom of
the flanges.
!
The rim of the recess, top and bottom, prevents the centrifugal force of the
bobbin throwing out the long hairs, and prevents their formation: Thus by the
use of iny Invention the lashing of the thread that is being spun is prevented,
enabling the frames to be run at a much higher speed, and the yarn produced is
much smoother and more regular in thickness; it is also stronger, and the weight
and natural lustre of the same is better preserved after the operation of genapping
or finishing.
Having thus described my said Invention, and the manner in which the same is
or may be performed, I have to state that I do not restrict myself to the precise
details herein shewn on the Drawings, but that what I believe to be novel and
original, and claim as the Invention secured to me by the herein-before in part
recited Letters Patent is, the arranging and formation of a recess in the top and

page_text: bottom flanges of spinning bobbins, substantially in the manner herein-before
described, and illustrated by the accompanying Drawings.
In witness whereof, I, the said Joseph Bottomley, have hereunto set my
hand and seal, this Seventh day of February, in the year of our Lord One
thousand eight hundred and seventy-eight.
Signed, sealed, and delivered by the
said Joseph Bottomley in the
presence of
JOHN WAUGH,
Engineer and Patent Agent,
Bradford.
