IMPROVEMENTS IN MEANS OR APPARATUS EMPLOYED WHEN SPINNING WORSTED OR OTHER FIBRES
Year: 1869

page_text: LETTERS PATENT to Henry Kershaw, of Laister Dyke, near Bradford,
in the County of York, Worsted Spinner,. for the Invention of
"IMPROVEMENTS IN MEANS OR APPARATUS EMPLOYED WHEN SPINNING
WORSTED OR OTHER FIBRES."
Sealed the 3rd June 1870, and dated the 10th December 1869.
PROVISIONAL SPECIFICATION left by the said Henry Kershaw at the
Office of the Commissioners of Patents, with his Petition, on the
10th December 1869.
I, HENRY KERSHAW, of Laister Dyke, near Bradford, in the County
3 of York, Worsted Spinner, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MEANS OR APPARATUS EMPLOYED WHEN
SPINNING WORSTED OR OTHER FIBRES," to be as follows:-
The object of the Invention is to prevent the formation of what is
commonly called "double," that is when in the spinning of worsted or
other fibres one thread breaks in its passage to the spindle and becomes
connected with or "doubles" on to the thread passing to another spindle,

page_text: and this Invention relates particularly to preventing the formation of
such double by the breakage of the threads between the delivery rollers
and the eyes through which the threads pass in the top board or rail.
For this purpose I appy an open frame with vertical bars to stand up
between the threads to each pair of spindles, so that when a thread
breaks in its passage to the top board or rail it will be kept from joining
or "doubling" on to an adjoining one. By these frames being formed open
the threads may be better seen in their passage to the spindles. I prefer
that these open frames should stand up at a short distance from each
pot eye, say, half an inch to three quarters of an inch from such pot eye,
also that they may be capable of turning on horizontal or vertical hinge
joints so that any one may be turned down or on one side to facilitate
the operation of "piecing up" again. These open frames may also be
made to fold in two. Their shape may be varied.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Kershaw in the Great Seal Patent Office on
the 8th June 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
KERSHAW, of Laister Dyke, near Bradford, in the County of York,
Worsted Spinner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of December, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
third 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, administrators, and assigns,
or such others as I, the said Henry Kershaw, my executors, adminis-
trators, 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 WHEN SPINNING WORSTED OR OTHER FIBRES," upon the condition
(amongst others). that I, the said Henry Kershaw, my executors or

page_text: 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.
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 the Invention is to prevent the formation of what is
commonly called "double," that is when in the spinning of worsted or
other fibres one thread breaks in its passage to the spindle and becomes
connected with or "doubles" on to the thread passing to another spindle,
and this Invention relates particularly to preventing the formation of
such "double" by the breakage of the threads between the delivery
rollers and the eyes through which the threads pass in the top board or
rail. For this purpose I apply an open frame with bars to stand up
between the threads to each pair of spindles, so that when a thread
breaks in its passage to the top board or rail it will be kept from joining
or "doubling" on to an adjoining one. By these frames being formed
open the threads may be better seen in their passage to the spindles.
I prefer that these open frames should stand up at a short distance from
each pot eye, say, half an inch to three quarters of an inch from such pot
eye, also that they may be capable of turning on horizontal or vertical
hinge joints so that any one may be turned down or on one side to
facilitate the operation of "piecing up" again. These open frames may
also be made to fold in two.
But that the Invention may be fully understood I will, by the aid of
the accompanying Drawings, proceed to describe means pursued by me
in carrying the same into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a section of a top board or rail of a spinning frame
with one of my improved open guard frames applied thereto; Figures 2
and 3 show a front view and an unner side view of a portion of such ton

page_text: a, a, is the top board or rail, and 6 the ordinary pot eyes therein
through which the threads pass, and by which they are guided in passing
from the delivery rollers to the spindles of the flyers. c, c, are the
guard frames standing up between the eyes b. According to the
arrangement of guard c, shown by these Figures 1, 2, and 3, and by the
separate views of one of them at Figures 4 and 5 they are connected by a
hinge joint c¹ to a plate c³ so as to be capable of being turned down on
to the board or rail when required for facility of piecing of broken
threads or otherwise. The plates c³ are fastened to the top board or rail
by screwing or by other convenient means.
Figures 6 and 7 show by plan and side views a modification of the
above in which the guard plates c are each formed with a vertical
socket so as to be capable of turning vertically on pins standing up
from the top board or rail.
Figures 8 and 9 show another modification in which in addition to
the socket c³ on which it may turn the guard is also formed to fold one
part on the other by having a hinge joint at c. These particulars may
however be varied as may also the shape of the guards.
Having thus described my Invention and means which I adopt in
carrying the same into effect, I would have it understood that what I
claim is, the application of open frames to stand up from the top board
or rail between the threads in their passage from the delivery rollers to
the eyes in such board or rail in means or apparatus employed when
spinning worsted or other fibres, substantially as explained.
In witness whereof, I, the said Henry Kershaw, have hereunto set
my hand and seal, this Third day of June, in the year of our
Lord One thousand eight hundred and seventy.
