page_text: LETTERS PATENT to John Henry Johnson, of 47, Lincoln's Inn Fields,
in the County of Middlesex, Gentleman, for the Invention of "IMPROVE.
MENTS IN THE TREATMENT OF YARNS INTENDED TO BE PRINTED."-A com-
munication from abroad by Charles Aubry, of Paris, in the Empire of
France.
Sealed the 17th December 1867, and dated the 19th June 1867.
PROVISIONAL SPECIFICATION left by the said John Henry Johnson at
the Office of the Commissioners of Patents, with his Petition, on the
19th June 1867.
I, JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of
Middlesex, Gentleman, do hereby declare the nature of the said Invention of
"IMPROVEMENTS IN THE TREATMENT OF YARNS INTENDED TO BE PRINTED," a com-
munication to me from abroad by Charles Aubry, of Paris, in the Empire of
France, to be as follows:-
This Invention relates to a mode of treating yarns of silk, wool, cotton, or
other fibrous material intended to be printed, and consists in weaving such
yarns into a temporary loose fabric by combining therewith warp threads of
cotton or other suitable material, such warp threads being by preference in
pairs at wide intervals, the yarn to be printed forming the weft of the tem-
porary fabric; the yarns so treated or woven into a temporary fabric are then
printed whilst still in the form of a fabric by any of the well known methods.

page_text: After having been printed, washed, and dried, the weft of the fabric is
separated or divided into hanks or skeins, to facilitate which operation the
warp threads are cut and drawn out; each portion forming a hank or skein
is pushed on to a pair of wooden or metal rods or pins, such rods or pins being
passed into the bends or loops of the yarn formed over the selvage cords or
threads, and in order to facilitate such insertion of the rods or pins the shedding
of the warp is so arranged that the warp thread on each side of the fabric
which is nearest to the selvage cord or thread must always be elevated or
depressed in company with the adjoining selvage cord or thread; by this
means the weft which passes, say, over the last outer warp thread will also pass
over the selvage cord or thread, and vice versa. The banks or skeins having
been thus separated and placed upon pins is wound off therefrom either in
the form of cops or on to bobbins, according as it is intended to be subsequently
used as weft or warp, suitable guide eyes being employed for guiding the yarn
properly from the skein to the cop or bobbin...
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Henry Johnson in the Great Seal Patent Office on the
18th December 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of Middlesex,
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of June, in the year of our Lord One
thousand eight, hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
John Henry Johnson, Her special license, that I, the said John Henry
Johnson, my executors, administrators, and assigns, or such others as I, the
said John Henry Johnson, my executors, administrators, or 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 "IMPROVE-
MENTS IN THE TREATMENT OF YARNS INTENDED TO BE PRINTED," a communication
to me from abroad by Charles Aubry, of Paris, in the Empire of France,
upon the condition (amongst others) that 1, the said John Henry Johnson,
my executors or administrators, by an instrument in writing under my hand and.

page_text: seal, 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 John Henry Johnson, 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, reference being had to the accompanying Diagram, and to
the letters and figures marked thereon, that is to say :-
The said Invention relates to a mode of treating yarns of silk, wool, cotton,
and other fibrous materials intended to be printed, and consists in weaving
such yarns into a temporary loose fabric by combining therewith warp threads
of cotton or other suitable material, such warp threads being disposed by
preference in pairs at wide intervals, the yarns to be printed forming the weft
of the temporary fabric; yarns so treated or woven into a temporary fabric
may then be printed or otherwise treated with coloring matter while. stilli
forming the weft of such fabric. After having been printed or otherwise
treated with coloring matter the, weft of the temporary fabric is separated or
divided into hanks or skeins, to facilitate which operation the warp..threads
are cut and drawn out. Each length or portion of the said temporary fabric
forming a hank or skein may be pushed on to a pair of wooden or metal rods
or pins, such rods or pins being passed into the bends or loops of the yarn
formed over the selvage cord, which may be either single or double (but I
prefer double) and the next inner cord or thread of the warp, which thread
for the sake of distinction I term the "loop thread" marked a' on the accom-
panying Diagram. In order to insure the ready opening of such bends or
loops in the yarn when inserting the before-mentioned rods or pins therein, the
shedding of the warp of the temporary fabric is so arranged that the loop
thread or warp thread a¹ which is nearest to the selvage cord or cords shall
always be elevated or depressed, as the case may be, in company with the said
selvage cord or cords, the two selvage cords a and the cord or loop thread a¹
in fact rising and falling in the weaving together. By this means the weft
which passes over the selvage cord or cords will also pass over the cord or
loop thread a', and vice versa.
In the Diagram before referred to I have represented only one edge of the
temporary fabric, the selvage cord being represented as composed of a double
thread, but it may be single if desired. The several warp threads a and the
particular one called the loop thread marked a' all pass through the same.
heddle, whilst those marked 6 pass through another heddle, consequently

page_text: during the operation of shedding the selvage cord (whether one or more be
used together) and the next.inner, warp thread or "loop thread" a¹ will
always be together either at the top or bottom of the shed, and thus an open
bend or loop without any crossing of the weft c between will be produced
over the selvage and the next inner warp thread or "loop thread" a'. The
temporary fabric having been separated into hanks or skeins, such hanks or
skeins may be then wound either in the form of other hanks, or of cops, or on
to bobbins, according as the yarn is intended to be subsequently used as weft
or warp.
Having now described and particularly ascertained the nature of the said
Invention, and. the manner in which the same is or may be used or carried
into effect, what I claim as the Invention secured to me by the herein-before
in part recited Letters Patent is, the making of a temporary fabric, in the
manner aforesaid, for the purpose of being printed or otherwise treated with
coloring matter, and subsequently brought into a suitable form for weaving
into permanent fabrics.
In witness whereof, I, the said John Henry Johnson, have to this my
Specification set my hand and seal, this Eighteenth day of December,
One thousand eight hundred and sixty-seven.
