IMPROVEMENTS IN MACHINES FOR SPINNING AND DOUBLING.
Year: 1861

page_text: LETTERS PATENT to William Kay, of Bolton-le-Moors, in the County of
Lancaster, Cashier, and Isaac Kay, of Lever Bridge, near Bolton-le-
Moors, aforesaid, Doubler, for the Invention of "IMPROVEMENTS IN
MACHINES FOR SPINNING AND DOUBLING.".
PROVISIONAL SPECIFICATION left by the said William Kay and Isaac
Kay at the Office of the Commissioners of Patents, with their Petition,
on the 27th May 1861.
We, WILLIAM KAY, of Bolton-le-Moors, in the County of Lancaster,
Cashier, and ISAAC KAY, of Lever Bridge, near Bolton-le-Moors, aforesaid,
Doubler, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINES FOR SPINNING AND DOUBLING," to be as follows:-
The object of our Invention is to arrest the progress of the yarn or thread
when it breaks between the rollers and the bobbin or spindle on to which it
is wound.
In performing our Invention the yarn or thread passes over a rail or other
suitable instrument, and under the weighted end of a tumbler lever; the
other end of this lever is held in position by the yarn or thread, consequently
as long as the yarn or thread passes forward to the bobbin or spindle the
weighted end of the lever is held above the rail, but as soon as the yarn or
thread breaks, the lever changes its position, and the sliver or yarn is caught

page_text: between the lever and the rail. The lever is so accurately balanced, that if a
single yarn passes between the rollers instead of a double yarn, the single
yarn being too weak to hold the lever down allows the weighted end to drop
on the rail, and thus stops the supply. By means of these improvements a
great saving in waste is effected, as the lapping of the yarn or thread on the
rollers is entirely or to a great extent avoided.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Kay and Isaac Kay in the Great Seal Patent
Office on the 26th November 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
KAY, of Bolton-le-Moors, in the County of Lancaster, Cashier, and ISAAC
KAY, of Lever Bridge, near Bolton-le-Moors, aforesaid, "Doubler, --send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh-day-of-May, -in-the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fourth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto us, the said William Kay and Isaac Kay, Her special licence that we,
the said William Kay and Isaac Kay, our executors, administrators, and
assigns, or such others as we, the said William Kay and Isaac Kay, 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 MACHINES
POR SPINNING AND DOUBLING," upon the condition (amongst others) that we,
the said William Kay and Isaac Kay, 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 William Kay and Isaac Kay, 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 (that is to say) :-

page_text: The object of our Invention is to arrest the progress of the yarn or thread
when it breaks between the rollers and the bobbin or spindle on to which it
is wound.
In performing our Invention the yarn or thread passes over a rail or other
suitable instrument, and under the weighted end of a tumbler lever, the other
end of this lever is held in position by the yarn or thread, consequently as
long as the yarn or thread passes forward to the bobbin or spindle the
weighted end of the lever is held above the rail, but as soon as the yarn or
thread breaks the lever changes its position, and the sliver or yarn is caught
between the lever and the rail. The lever is so accurately balanced that if a.
single yarn passes between the rollers instead of a double yarn, the single
yarn being too weak to hold the lever down allows the weighted end to drop.
on the rail, and thus stops the supply. By means of these improvements a.
great saving in waste is effected, as the lapping of the yarn or thread on the
rollers is entirely or to a great extent avoided.
And in order that our Invention may be fully understood and readily
carried into effect, we will proceed to describe the accompanying Sheet of
Drawings, reference being had to the figures and letters marked thereon.
Fig. 1 is a section through part of an ordinary doubling frame to which our
improvements are applied, and Fig. 2 is a plan of the same.
a is the trough containing the liquid through which the single yarns,
indicated by the lines b, are drawn; c, the rail to which the glass guides d
are attached; e, the cap bar; f, the lower roller; g, the top roller; and h, the
bobbin on to which the doubled yarn is wound. These parts, and the others
requisite to complete the frame, are made in the usual manner. To the rail c
is fixed the rail i, the upper edge of which is made, by preference, bevelled;
to the rail c are fixed studs for the tumbler levers ; to hinge upon; the lower
edge of these levers have bevelled recesses corresponding to the bevelled edge
of the rail i, and to the upper end of the tumbler levers are fixed the wires k,
which are taken over the cap bar c, and terminate in a spout l. The full lines
in Fig. 1 represent the double yarn passing through the spout ?, which is placed
between the roller f and the spindle m, the double yarn holding the weighted
end of the tumbler lever j above the two single yarns which are passing over
the rail i. As soon as the doubled yaru breaks, the spout. being no longer
held in position by the doubled yarn, is raised by the descent of the tumbler
lever j, which then drops on to the rail i, and arrests the progress of the
single yarns, thereby preventing the lapping of the yarn on to the rollers,
which in machines of the ordinary construction causes a considerable amount
of waste. The tumbler lever j is so accurately balanced, that if a single yarn

page_text: passes between the rollers f and g, instead of a double yarn, the single yarn
being too weak to hold the spout 7 down, allows the weighted lever j to drop
on to the rail i, and thus stops the supply.
This improved combination of parts for, arresting the progress of the yarn
when it breaks between the drawing rollers and the bobbin or spindle is also
applicable to the machines for spinning called "throstles," and the requisite
modification in the details will readily suggest themselves to any mechanic
conversant with this class of machinery.
Having thus stated the nature of our Invention, and described the manner
of performing the same, we declare that we claim the improved combination
of parts for arresting the progress of the yarn or thread when it breaks between
the rollers and the bobbins or spindles of spinning and doubling machines, as
shewn and described.
In witness whereof, we, the said William Kay and Isaac Kay, have
hereunto set our hands and seals, the Twenty-second day of November,
--in the year of our Lord One thousand eight hundred and sixty-one.
