Year: 1869

page_text: LETTERS PATENT to John Bottomley, of Bradford, in the County of
York, Agent, and Sidney Emsley, of Oakenshaw Mills, Low Moor,
near Bradford, aforesaid, Worsted Spinner, for the Invention of
IMPROVEMENTS IN SPINNING FIBROUS SUBSTANCES.
Scaled the 20th May 1870, and dated the 22nd November 1869.
PROVISIONAL SPECIFICATION left by the said John Bottomley and
Sidney Emsley at the Office of the Commissioners of Patents, with
their Petition, on the 22nd November 1869.
We, JOHN BOTTOMLEY, of Bradford, in the County of York, Agent,
and SIDNEY EMSLEY, of Oakenshaw Mills, Low Moor, near Bradford,
aforesaid, Worsted Spinner, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN SPINNING FIBROUS SUBSTANCES," to be as
follows:-
This Invention consists in what we call double spinning, that is,
spinning a roving of fibrous substance around a previously spun thread,

page_text: and the object is to obtain lustrous yarns from a combination of lustrous
and non-lustrous fibrous substances, for which purpose wo pass a thread
or threads of worsted or woollen yarn betwixt the drawing rollers of the
ordinary spinning frame without giving any further draught or elongation
thereto, and simultaneously we pass a roving or rovings of mahair, alpaca,
silk, or other lustrous fibrous substance between the back or feed rollers,
and thence betwixt the drawing rollers, which draw or clongate the same
in the usual manner, and which is then spun along with and upon the
surface of the worsted or woollen yarn.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Bottomley and Sidney Emsley in the Great
Seal Patent Office on the 21st May 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, JOHN
BOTTOMLEY, of Bradford, in the County of York, Agent, and SIDNEY
EMSLEY, of Oakenshaw Mills, Low Moor, near Bradford, aforesaid,
Worsted Spinner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Twenty-second day of November, 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 suc-
cessors, give and grant unto us, the said John Bottomley and Sidney
Emsley, Her special licence that we, the said John Bottomley and
Sidney Emsley, our executors, administrators, and assigns, or such
others as we, 'the said John Bottomley and Sidney Emsley, our exe-
cutors, 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 SPINNING FIBROUS SUBSTANCES," upon the condition (amongst others)
that we,
the said John Bottomley and Sidney Emsley, our executors or

page_text: administrators, by an instrument in writing under our, 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 Scal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that we, the said John Bottomley and Sidney
Emsley, 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) :-
This Invention consists in what we call double spinning, that is,
spinning a roving of fibrous substance around a previously spun thread,
and the object is to obtain lustrous yarns from a combination of lustrous
and non-lustrous fibrous substances, for which purpose we pass a thread
or threads of worsted or woollen yarn betwixt the drawing rollers of
the ordinary spinning frame without giving any further draught or
elongation thereto, and simultaneously we pass a roving or rovings of
mohair, alpaca, silk, or other lustrous fibrous substance between the
back or feed rollers, and thence betwixt the drawing rollers, which draw
or elongate the same in the usual manner, and which lustrous yarn is
then spun along with and upon the surface of the worsted or woollen or
non-lustrous yarn.
By this improvement we can utilize or economise yarns spun of
lustrous fibres, and yet produce more lustrous textile fabrics from such
yarns than heretofore, and we also produce a "fullness in the cloth or
fabric not obtainable by the ordinary methods of spinning.
In carrying this Invention into practical operation it will be observed
that we may employ any ordinary spinning machinery suitable for
effecting the object or purpose in manner as herein-before set forth,
that is, for the spinning a roving of lustrous fibres around a previously
spun thread or yarn of non-lustrous fibres.
Having thus described the nature of our said Invention and the
manner in which the same is or may be, performed or carried into.
practice, we would have it understood that what we claim as our Inven-

page_text: tion is, the method of producing lustrous yarns by spinning a roving of
lustrous fibres around a yarn or yarns of non-lustrous fibres.
In witness whereof, we, the said John Bottomley and Sidney
Emsley, have hereunto set our hands and seals, this Eighteenth
day of May, in the year of our Lord One thousand eight
hundred and seventy.
Signed, sealed, and delivered by the
within-named John Bottomley and
Sidney Emsley, in the presence of
EDWARD TASKER.
