Year: 1852

shaw, near Leeds, for bis Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF YARNS AND FABRICS WHEN COTTON WOOL AND SILK
ARE EMPLOYED," bearing date at Westminster, the Thirty-first day of
July, One thousand eight hundred and fifty-two, and to which a
Specification was duly inrolled.
DISCLAIMER AND MEMORANDUM OF ALTERATION proposed
to be entered by the said William 'Ackroyd, pursuant to the Statutes in
that case made and provided.
In the said Specification I, the said William Ackroyd, did describe the
Invention to consist of a certain manufacture of yarns of wool and cotton
combined, and also to consist of a certain manufacture of yarns. of. wool and
silk combined; and I have since been advised that so much of the Invention
as consisted of combining wool and silk was not new, for which reason I wish
to disclaim, and I do hereby disclaim, the words "and silk" in the title; and
to make the same. read correctly after such Disclaimer, I alter the title by
introducing the word.." and "after the word.cotton and before the-word-wool.
And for the same reason I wish to disclaim, and I do hereby disclaim, the
following parts of my said Specification, that is.to say, the words "or wool and
silk," also the paragraph:"In like manner may. wool and silk waste be
employed together, they being first-mixed and then combed together or combed
separately and mixed by the subsequent-processes of preparing for spinning;"
also the words: "and also that it is not new to combine wool and silk when
manufacturing yarns;" and also the words: "also wool and silk." And in
order to correct an error in the following paragraph in the Specification,
videlicet, "From the above description it will be seen that the object of the

page_text: Invention is to obtain mixed fibres of the kinds above mentioned, with a view
to make yards and weave fabrics thereof," I strike out the word "yards," and
introduce the word yarns..

ACKROYD, of Birkenshaw, near Leeds, send greeting.
COME, I, WILLIAM
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Thirty-first day of
July (One thousand eight hundred and fifty-two), in the sixteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Ackroyd, my exors, adññors, and assigns, Her special
licence, full power, sole privilege and authority, that I, the said William
Ackroyd, my exors, aduiors, and assigns, or such others as I, the said William
Ackroyd, my exors, adiñors, or assigns, should at any time agree with, and
no others, from time to time and at all times during the term of years therein
expressed, should and lawfully might make, use, exercise, and vend, within
England, Wales, and the Town of Berwick-upon-Tweed, my Invention of
"IMPROVEMENTS IN THE MANUFACTURE OF YARNS AND FABRICS WHEN COTTON,
WOOL, AND SILK ARE EMPLOYED;" in which said Letters Patent is contained a
proviso, that I, the said William Ackroyd, shall cause a particular description
of the nature of my said Invention, and in what manner the same is to be
performed, by an instrument in writing under my hand and seal, to be
inrolled in Her Majesty's High Court of Chancery within six calendar months
next and immediately after the date of the said in part recited Letters Patent,
as in and by the same, reference being thereunto had, will more fully and at
large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Ackroyd, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, that is to say:
The improvements consist in combining cotton and wool, or wool and silk,
when they have been combed; or combining them uncombed and then combing
them, and the use of these, so combed and combined, in the manufacture of
fabrics.
In order that my Invention may be most fully understood and readily
carried into effect, I will proceed to describe the means pursued by me when
cotton, and wool are to be combined. I employ them of as nearly as may be
of the like staple or length of fibre, and I can mix them either before or after
combing them; I prefer to mix them before they are combed (and this may
be done by carding them together or separate), and then to feed the carded
fibres together into a combing machine, and I cause them to be combed
together.
The act of combing (whether they have been previously carded together
or not), and the subsequent processes of preparing for spinning, will more-
intimately blend the two descriptions of fibres, or the wool only may be
combed, and carded cotton combined or mixed therewith, in preparing them
for spinning.
The relative quantities of the wool and cotton may be greatly varied, and
the effects producible by different mixtures will also greatly vary, particularly
if the yarns or fabrics made therefrom be dyed or printed, as different effects
of colour will result than when using all cotton, or all wool, and the manu-
facturer will cause the one class of fibre to predominate, or the other, according
as he wishes the yarns and fabrics more nearly to approach in character and
appearance yarns or fabrics made wholly of the one or other fibre.
In like manner may wool and silk waste be employed together, they being
first mixed and then combed together, or combed separately and mixed by the
subsequent processes of preparing for spinning.
I would remark, that I am aware that it is not new to combine cotton
and wool, and also that it is not new to combine wool and silk, when manu--
facturing yarns; the novelty of my Invention consists in employing such fibres
in combination only when they are subjected to the process of combing either
before or after mixing.
From the above description it will be seen that the object of the Invention
is to obtain mixed fibres of the kinds above mentioned with a view to make
yards and weave fabrics thereof, such mixed fibres being placed longitudinally

page_text: side by side by the act of combing, whether such combing is performed after or
before mixing, and they will be suitable for spinning into yarns in like manner
to what combed wool is now spun, and such yarn may then be woven into
fabrics, either alone (both in respect to warp and weft) or with other yarn in
the warp or weft; by which means peculiar fabrics may be produced, par-
taking more or less of the particular fibre which is most or least largely used
in the yarn, and the one or other fibre may be used in quantity in each
case, according as it is desired that the yarn should partake more or less of
the character of the one or the other fibre.
Having thus described the nature of my Invention and the manner of
performing the same, I would have it understood that I do not confine myself
to the details, so long as the peculiar character of my Invention be retained.
But what I claim is, the preparing cotton and wool, also wool and silk, by
combining them before or after combing them, and causing such fibres so
combined to be spun and woven in fabrics.
In witness whereof, I, the said William Ackroyd, have hereunto set my
hand and seal, this Twenty-eighth day of January, in the year of our
Lord One thousand eight hundred and fifty-threc.
