IMPROVEMENTS. IN. THE MANUFACTURE OF WARP. LACE
Year: 1859

page_text: LETTERS PATENT to Thomas Herbert; of the firm of Thomas Herbert
and Company,. of Nottingham, and Edward: Whitaker, also of Notting-
ham; for the Invention of "IMPROVEMENTS. IN. THE MANUFACTURE OF WARP.
LACE."
Sealed the 8th July. 1859, and dated. the 13th. January 1859..
PROVISIONAL SPECIFICATION left by the said Thomas Herbert and
Edward Whitaker at the Office of the Commissioners of Patents, with
their Petition, on the 13th January 1859.
We, THOMAS HERBERT, of the firm of Thomas Herbert and Company, of
Nottingham, and EDWARD WHITAKER, also of Nottingham,. do hereby declare
the nature of the Invention for "IMPROVEMENTS IN THE MANUFACTURE OF WARP
LACE," to be as follows:-
This Invention has for its object improvements in the manufacture of warp
lace. For these purposes three warp threads work with a needle, two of
which are called twisting threads, and one a pillar thread, and in the working
of the machine one of the twisting threads is caused to lap over a needle, and
the other twisting thread is caused to traverse under the same, and both
threads are caused to rise up and to pass back over the same needle, by which
means the first-mentioned twisting thread will be unlapped from the needle,
and the second-mentioned twisting thread will be lapped on the needle, and

page_text: the two twisting threads will be twisted together. The pillar thread is then
caused to lap on the needle, and its lapping is pressed under the beard of the
needle;
but the lapping of the twisting thread is knocked over with the
previous loop of the pillar thread. In making purl edges in this manner,
and also at times in other parts of a breadth of lace, longitudinal threads
are laid in in such manner as to pass between the twists of the twisting
threads, by which means the several pairs of the twisting threads will be held
together even when pillar threads have been withdrawn.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Herbert and Edward Whitaker in the Great Seal
Patent Office on the 13th July 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
HERBERT, of the firm of Thomas Herbert and Company, of Nottingham, and
EDWARD WHITAKER, also of Nottingham, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of January, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-second year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Thomas Herbert and Edward Whitaker, Her, special licence that
we, the said Thomas Herbert and Edward Whitaker, our executors, admini-
strators, and assigns, or such others.-as we, the said Thomas Herbert and
Edward Whitaker, our executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 MANUFACTURE OF WARP LACE," upon the condition (amongst
others) that we, the said Thomas Herbert and Edward Whitaker, our
executors or administrators, by an instrument in writing under our or their
hands and seals, or under the hand and seal of one of us or them, 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 Herbert and Edward
Whitaker, do hereby declare the nature of the said Invention, and in what

page_text: manner the same is to be performed, to be particularly described and
ascertained in and by the following statement thereof, that is to say:-
This Invention has for its object improvements in the manufacture of warp
lace. For these purposes three warp threads work with a needle, two of
which are called twisting threads and one a pillar thread, and in the working
of the machine one of the twisting threads is caused to lap over a needle, and
the other twisting thread is caused to traverse under the same, and both
threads are caused to rise up and to pass back over the same needle, by which
means the first-mentioned twisting thread will be unlapped from the needle,
and the second-mentioned twisting thread will be lapped on the needle," and
the two twisting threads will be twisted together. The pillar thread is then
caused to lap on the needle, and its lapping is pressed under the beard of the
needle, but the lapping of the twisting thread is knocked over with the
previous loop of the pillar thread. In making purl edges in this manner, and
also at times in other parts of a breadth of lace, longitudinal threads are laid
in such manner as to pass between the twists of the twisting threads, by which
means the several pairs of the twisting threads will be held together even
when pillar threads have been withdrawn."
.
.
Having thus stated the nature of our said Invention, we will proceed
more fully to describe the manner of performing the same.
In carrying out the Invention, there will require to be at least three guide
bars; but where it is desired to have a mixture of the peculiar work produced
according to the Invention, and other descriptions of work in the same breadth
of lace, and also where it is desired that the same threads should be at one
time caused to work according to the Invention, and at another time to make
other descriptions of work, then it will be necessary to employ a proportionably
large number of guide bars, or to have the guides independent of each other,
using suitable cuts of wheels or jacquard or other pattern surfaces to actuate
the guide bars and the independent guides, as are well understood.
And in
arranging the pattern of work to be produced, such cuts of wheels or pattern
surfaces are to be so prepared that they will for the time the sets of three
threads (working with any of the needles) are to be actuated according to
our Invention, cause such sets of three threads to be working with their
needles in such manner that two of each set of the threads (which, for
distinction, we call twisting threads,) shall work with the other, or what we
call the pillar thread in the following manner, that is to say:-One of the
twisting threads shall be caused to lap over a needle, and the other twisting
thread shall be caused to traverse under the same needle, and that then both
of the twisting threads shall be caused to rise up and pass back over the same

page_text: needle, by which the first-mentioned twisting thread will be unlapped from the
needle, and the second-mentioned twisting thread will be lapped on the needle,
and the two twisting threads will be twisted together. The pillar or third thread
is then to be lapped on to the same needle, and its lapping is to be pressed
under the beard of the needle; but the lapping of the twisting thread is to be
knocked over with the previous loop of the pillar thread. In this manner
may the two threads selected to be the twisting: threads of each needle be
caused to act for a time, and then such two threads and the pillar threads of
any of the needles may for a time be caused to be actuated to produce other
descriptions of work, such as are well understood when making warp fabrics
with three threads to each needle. When making purl edges by actuating the
threads as above described, longitudinal threads may be introduced or laid in
the work, as is well understood, and similar longitudinal threads may be laid
into the other parts when working as above described, which will admit of the
pillar threads being removed when the other classes of work combined with that
made according to our Invention will admit of such pillar threads being
withdrawn.
In witness whereof, we, the said Thomas Herbert and Edward Whitaker;
have hereunto set our hands and seals, this Ninth day of July,
in the year of our Lord One thousand eight hundred and fifty-
nine.
THOMAS HERDERI.
