page_text: LETTERS PATENT to Thomas Craven, Manager of a Mill, and Matthew
Pickles, Overlooker, both of Birstall, in the County of York, for the
Invention of "IMPROVEMENTS IN WEAVING."
PROVISIONAL SPECIFICATION left by the said Thomas Craven and">
Matthew Pickles at the Office of the Commissioners of Patents, with
their Petition, on-the-20th-October 1855..
We,.
.THOMAS CRAVEN, Manager of a Mill, and MATTHEW PICKLES, Over-
looker, both of Birstall, in the County of York, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN WEAVING" to be as follows:-.
In using a second harness to the jacquard action in such manner, that, in
addition to the portion of the warp raised or depressed for ordinary figure..
weaving, any thread or threads may be raised or dropped by the jacquard
action in connexion with the half heald usually employed in gauze weaving;
and in the application of this arrangement to the production of a floated figure
on a cross gauze ground in any fabric, such floated figure having hitherto been
only produced loosely on the surface, whereas by this Invention it would be
woven into the fabric.

by the said Thomas Craven and Matthew Pickles in the Great Seal
Patent Office on the 18th April 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wе, THOMAS

WHEREAS Her most Excellent Majesty Queen Victoria; by Her Letters
Patent, bearing date the Twentieth day of October," in the year of our Lord
One thousand eight hundred and fifty-five, in the nineteenth year of Her

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 WEAVING,"
upon the condition (amongst others) that we, the said Thomas Craven and
Matthew Pickles, our executors or 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
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 Thomas Craven and Matthew Pickles,
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:
The object of our Invention is the production of a floated pattern in gauze
by a modification of the mounting of the ordinary jacquard loom. "It consists
in using a second harness to the jacquard action in such a manner, that, in
addition to the portion of the warp- raised or depressed for ordinary figure
weaving, any thread or threads, may be raised or dropped by the jacquard
action in connection with the half heald usually employed in gauze weaving;
and in the application of this arrangement to the production of a floated figure
on a cross gauze ground in any fabric, such floated figure having hitherto been

page_text: only produced loosely on the surface, whereas by this Invention it is woven
into the fabric.
In place of the standards and half healds commonly used in gauze weaving,
we employ a second harness and one half heald, the warp threads being drawn
through loops or mails in such second harness, and thus raised or dropped in
any required number by the usual action of the pattern cards, or other means
in use for raising and depressing the threads necessary for weaving figured
goods. The half heald is used in the ordinary mode employed in gauze
weaving to produce the cross shed, every loop or mail in such half heald passing
through a loop or mail in the harness, and having the next warp thread passing
through its loop or mail.
The effect of the foregoing arrangement is, that as any of the warp
threads are depressed, the weft is floated over them, and the required pattern
produced.
Having now fully described our said Invention, what we claim under the
above in part recited Letters Patent is, the production of a floated pattern
on a gauze ground in the jacquard loom in such a manner that the pattern
thus produced, is completely woven into the fabric, the same being effected
substantially in the mode herein-before set forth.
In witness whereof, we, the said Thomas Craven and Matthew Pickles,
have hereunto set our hands and seals, this Fifteenth day of April,
in the year of our Lord One thousand eight hundred and fifty-six.

TOTO
MATTHEW PICKLES. (L.S.)
