IMPROVEMENTS IN MEANS OR APPARATUS EMPLOYED IN SPINNING WORSTED AND OTHER FIBRES
Year: 1868

page_text: LETTERS PATENT to Henry Kershaw, of Laister Dyke, near Bradford,
in the County of York, for the Invention of "IMPROVEMENTS IN
MEANS OR APPARATUS EMPLOYED IN SPINNING WORSTED AND OTHER
FIBRES."
Sealed the 5th September 1868, and dated the 13th March 1868.
PROVISIONAL SPECIFICATION left by the said Henry Kershaw at
the Office of the Commissioners of Patents, with his Petition, on
the 13th March 1868.
I, HENRY KERSHAW, of Laister Dyke, near Bradford, in the County
of York, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MEANS OR APPARATUS EMPLOYED IN SPINNING WORSTED AND
OTHER FIBRES," to be as follows:-
The object of these improvements is to prevent what is commonly
called " double," or when a thread breaks in its passage from the
delivery rollers to the flyers of the spinning frame, its uniting to
and twisting with the
with the thread to another flyer below the top
rail. For this purpose I apply under the top rail and between each
pair of spindles a guard extending downwards by preference a much
shorter distance than those ordinarily used, say to just below the top

page_text: of the spindle and inclined to a considerable angle from the front
thereof towards the lowest point, and then horizontally or nearly so
to the back point where it may be level with the back of the under
side of the top board to ensure the broken thread running to the lowest
part of such guard and becoming broken. These guards may be
formed of metal plates or by the cutting away of the under side of the top
board or guide rail, or otherwise.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Kershaw in the Great Seal Patent Office
on the 12th September 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
KERSHAW, of Laister Dyke, near Bradford, in the County of York,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of March, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Kershaw, Her special
licence, that I, the said Henry Kershaw, my executors, adminis-
trators, and assigns, or such others as I, the said Henry Kershaw,
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 MEANS OR APPARATUS EMPLOYED IN SPINNING WORSTED
AND OTHER FIBRES," upon the condition (amongst others)" that I, the
said Henry Kershaw, 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 immediately after the date of the said
Letters Patent.

page_text: NOW KNOW YE, that I, the said Henry Kershaw, do hereby declare
the nature of the 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, that is to say:-
The object of these improvements is to prevent what is commonly
called "double," or when a thread breaks in its passage from the
delivery rollers to or through the flyers of the spinning frame and by
its end becoming loose unites with the thread, passing to another flyer
below the top rail to prevent this loose thread from continuing to twist
with such other thread. For this purpose under the top rail between
each pair of spindles and by preference about half an inch from the
centre of each spindle I apply a guard extending downwards a much
shorter distance than the guards ordinarily used, say to just below the
top of the spindle or other part applied thereto, and in form inclined
at the front edge to a considerable angle from the front of such top
rail towards the lowest part thereof, and then horizontal or nearly so to
the back point where it may be level with the back of the under side
of the top board.
The Drawing Figure 1 shows a front view; Figure 2, a section; and
Figure 3, an under side view of a portion of a top rail of a spinning
frame with guards a applied thereto according to my improvements;
Figures 4 and 5 shew a side and end view of one of the guards
separately full size. These guards a are, as shown, formed of metal,
but they may be formed of other suitable material. It will be seen
that at the front edge they are inclined at a¹ to a considerable angle
from the upper part of them to the under side or edge a² thereof in
order that any loose ends of threads, such as referred to, may when
they cross from passing to one spindle to the thread of another be
more readily carried down such incline and broken by passing under
the bottom edge thereof, whilst such loose ends of threads which become
connected with threads to other spindles by passing at once under
such guards will be broken thereby in like manner. The pot eyes to
guide the threads to the spindles are indicated at b, b. The position
of the guard a and line of cutting away of the front edge a¹ and under
side a² thereof may be somewhat varied.
Having thus described my Invention and means which I adopt in
carrying the same into effect, I would have it understood that what

page_text: I claim is, the application of guards a formed and applied substantially
as described.
In witness whereof, I, the said Henry Kershaw, have hereunto
set my hand and seal, this Ninth day of September, in the year
of our Lord One thousand eight hundred and sixty-eight.
HENRY KERSHAW. (L.S.)
