LETTERS PATENT to Henry Kershaw, of Laister Dyke, near Bradford,
in the County of York, Worsted Spinner, for the Invention of “Iм-
PROVEMENTS IN MEANS OR APPARATUS EMPLOYED IN SPINNING WORSTED AND
OTHER FIRDS"
PROVISIONAL SPECIFICATION left by the said Henry Kershaw at the
Office of the Commissioners of Patents, with his Petition, on the
14th February 1873.
I, HENRY KERSHAW, of Laister Dyke, near Bradford, in the County
of York, Worsted Spinner, 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
In the spinning process the yarns often break between the feed roller
and the spinning spindle, when the broken yarn in flying round generally
catches on to the unbroken yarn, passing to a neighboring spindle,
and runs on with it, by which what is called "double" or irregular yarn
is produced.

page_text: Various means have been adopted by myself and others to remedy this
evil, and my present Invention has for its object to remedy it by
extending the tubular guides or eyes, through which the yarn passes, in
the top board or rail upwards, so as to form a continuous tubular guard
of small diameter to an extent of, say about half an inch, but this may
be less or more above such board or rail, and inclined towards the feed
roller.
These extensions may be obtained by extensions of the ordinary pot
eyes, or by additional pieces of tubes applied above them, and of the
same or different material. Brass, pot ware, glass, or other material
may be used, and they have a slit or opening to each extending down-
wards, corresponding with that to the eye for the free passage of the
thread thereto, when desired by the operator.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Kershaw in the Great Seal Patent Office
on the 11th August 1873.
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 Fourteenth day of February, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Kershaw, Her special license
that 1, the said Henry Kershaw, my executors, administrators, 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 adminis-
trators, by an instrument in writing under my, or their, or one of

page_text: 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 :—
In the spinning process the yarns often break between the feed roller
and the spinning spindle, when the broken yarn hanging from the feed
means will drop on the top board, and owing to there being no pro-
tection to the yarns just above the top board, such yarn frequently
catches on to the unbroken yarn, passing through the top board to a
neighbouring spindle, and runs on with it, by which what is called
"double" or irregular yarn is produced.
Various means have been adopted by myself and others to remedy
this evil, and my present Invention has for its object to remedy it by
extending the tubular guides or eyes through which the yarn passes in
the top board or rail upwards, so as to form a continuous tubular guard
of small diameter to an extent of say about half an inch, but this may
be less or more above such board or rail and inclined towards the feed
roller or otherwise.
These extensions may be obtained by extensions of the ordinary pot
eyes or by additional pieces of tubes applied above them, and of the
same or different material. Brass, pot ware, glass, or other material may
be used, and they have a slit or opening to each, extending downwards,
corresponding with that to the eye for the free passage of the thread
thereto when desired by the operator.
But that the Invention may be fully understood, I will by the aid
of the accompanying Drawing proceed to describe means pursued by
me in carrying the same into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews by a sectional view, Figure 2 by a front view, and

page_text: In this case a is the rail and 6 an ordinary pot eye thereto for the pur-
pose of guiding the yarn to be spun in its passage from the feed rollers
to the spinning spindle; c is the slit or passage to the opening in the
pot eye, and d is the extension guide, which according to my Invention
is extended upwards above the pot eye or opening thereof, so that in the
event of the yarn breaking, that which hangs from the feed roller may
be prevented by such extension tubes from at once passing along the
top of such rail to take hold of the thread passing to an adjoining
spindle; d¹ is the opening for the passage of yarn to the interior of the
tube d.
Figures 4, 5, and 6, shew a slight modification of the improvements
in which the pot eye is applied in the upper part of tube d at d², and in
which a slight variation of the form of the parts.is indicated, but such
may be varied, and if desired the whole of the tube d may be formed of
pot ware, glass, or other such material.
Having thus described my Invention, and means which I adopt in
carrying the same into effect, I would have it understood that I do not
confine myself to the precise arrangement or form of parts as shewn
and described, as the same may be varied without departing from the
peculiar character of the Invention, but what I do claim is the improve-
ments in means or apparatus employed in spinning worsted and other
fibres by the use of tubular extension guides substantially as described.
In witness whereof, I, the said Henry Kershaw, have hereunto set
my hand and seal, this Eighth day of August, in the year of our
Lord One thousand eight hundred and seventy-three.
