Fields, in the County of Middlesex, Gentleman, for the Invention
of "AN IMPROVED TEXTILE FABRIC APPLICABLE AS BLANKETS FOR PRINTING
PRESSES, AND FOR OTHER USEFUL PURPOSES."--A communication from
abroad by Jean Louis Delègue, of Paris, in the Empire of France.
Sealed the 23rd March 1869, and dated the 7th October 1868.
PROVISIONAL SPECIFICATION left by the said John Henry Johnson
at the Office of the Commissioners of Patents, with his Petition,
on the 7th October 1868..
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 for "AN IMPROVED TEXTILE FABRIC APPLICABLE AS BLANKETS FOR
PRINTING PRESSES, AND FOR OTHER USEFUL PURPOSES," a communication to me
from abroad by Jean Louis Delègue, of Paris, in the Empire of France,
to be as follows

page_text: presses, and may be applied to various other useful purposes; for
example, the novel fabric may be used in machines for printing woven
fabrics or textile materials either as a covering for the rollers or
blankets.
In manufacturing the improved fabric or blanket, to which the
Inventor distinguishes by the name of the Delègue blanket," a
warp of silk, spun floss silk, or cotton is used, such warp being worked
by a satin tweel mount, as is well understood by weavers; combined with
this warp there is a woollen weft also operated as for satin fabrics. The
fabric thus produced is to be coated on the satin warp side or face with a
solution of caoutchouc, so that the fabric presents a perfectly smooth and
pliable surface on one side. The other face remains without any finish
whatever, presenting the appearance of a fabric composed entirely of
wool. The improved "blanket " or fabric possesses considerable strength
and solidity, and has one of its faces as even and smooth as paper, whilst
by reason of the woolen warp visible only on one face considerable
elasticity or yielding in the direction of the thickness of the fabric is
obtained, rendering it specially applicable to printing machinery.
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 7th April 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HENRY JOHNSON, of 47, Lincoln's Inn Fields in the County of Mid-
dlesex, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of October, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-
second 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, adminis-
trators, 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,

page_text: the Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
TEXTILE FABRIC APPLICABLE AS BLANKETS FOR PRINTING PRESSES, AND FOR OTHER
USEFUL PURPOSES," a communication from abroad by Jean Louis Delègue,
of Paris, in the Empire of France, upon the condition (amongst
others) that I, the said John Henry Johnson, my executors or adminis-
trators by an instrument in writing under my hand and 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, that is to say:
The said Invention consists of a novel textile fabric which will be
found useful as a substitute for the ordinary blankets employed in
printing presses, and may be applied to various other useful purposes;
for example, the novel fabric may be used in machines for printing
woven fabrics or textile materials either as a covering for the rollers or
as blankets.
In manufacturing the improved fabric or blanket which the Inventor
distinguishes by the name of the "
Delègue blanket, a warp of silk, spun
floss silk, or cotton is used, such warp being worked by a satin tweel
mount as is well understood by weavers, combined with this warp there
is a woollen weft also operated as for satin fabrics. The fabric thus
produced is to be coated on the satin warp side or face with a solution
of caoutchouc, so that the fabric presents a perfectly smooth and pliable
surface on one side. The other face remains without any finish whatever,
presenting the appearance of a fabric composed entirely of wool. The
improved "blanket" or fabric possesses considerable strength and solidity,
and has one of its faces as even and smooth as paper, whilst by reason of
the woollen warp visible only on one face considerable elasticity or
yielding in the direction of the thickness of the fabric is obtained,
rendering it specially applicable to printing machinery.
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, I would observe in conclusion that what I
consider to be novel and original, and therefore claim as the Invention

page_text: secured to me by the herein-before in part recited Letters Patent is, the
peculiar construction of fabric as and for the purposes herein-before
described.
In witness whereof, I, the said John Henry Johnson, have to this
my Specification set my hand and seal, the Seventh day of April,
One thousand eight hundred and sixty-nine.
J. HENRY JOHNSON. (L.S.)
