IMPROVEMENTS IN THE MANUFACTURE OF TWIST LACE IN TWIST LACE OR BOBBIN NET MACHINERY
Year: 1860

page_text: LETTERS PATENT to Moritz Jacoby, of Nottingham, for the Invention of
"IMPROVEMENTS IN THE MANUFACTURE OF TWIST LACE IN TWIST LACE OR
BOBBIN NET MACHINERY."
Sealed the 7th November 1861, and dated the 21st August 1860.
PROVISIONAL SPECIFICATION left by the said Moritz Jacoby at the
Office of the Commissioners of Patents, with his Petition, on the
21st August 1860.
I, MORITZ JACOBY, of Nottingham, do hereby declare the nature of the
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF TWIST LACE IN TWIST
LACE OR BOBBIN NET MACHINERY," to be as follows:--
This Invention has for its object improvements in the manufacture of twist
lace in twist lace or bobbin net machinery, and consists in producing a peculiar
combination of meshes, weavings, and edges or heads, with a view to obtain
better imitations by twist lace machinery of the Valenciennes laces produced
on the pillow by hand. For these purposes the ground of each breadth of
lace is composed of meshes, the pillars and crossings of which are each
composed of two bobbin threads and two warp threads, which in the pillars
are plaited or worked together, and which in the weavings or finings in the
body of the lace are all caused to act as warp threads, and they are wefted or
shot by two or more extra independent warp threads in making each spot or

page_text: piece of weaving, which two or more warp threads are worked into the pillars
of the ground of the lace, though they may, if desired, be so worked as to
admit of being cut away between the succeeding spots or pieces of weavings,
though in place of the two or more extra warp threads two or more of the
ordinary warp threads might be used. The weaving in the body of the lace
might also be produced by one or more carriage threads, or may be by a
carriage and warp thread conjointly shooting through several independent warp
threads, which warp threads can be worked in the lace if the pattern admits
it, or clipped off where not wanted. But I make no claim to the production
of the net and weaving or fining separately, as above described. The
peculiarity of my Invention consists in combining such net and weaving or
fining (in the body of the lace) with what may be called Valenciennes edges
or heads, such edges or heads to consist in each case of several independent
warp threads, which are caused to be shot or wefted. with one or more bobbin
threads, or it may be with a bobbin thread and independent warp thread
conjointly, the purls being produced as heretofore, and in producing by this
combination an article by twist lace or bobbin net machinery very similar to
Valenciennes laces produced on pillow by hand.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Moritz Jacoby in the Great Seal Patent Office on the
20th February 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME; I,. MORITZ
JACOBY,. of Nottingham, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of August, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did,, for Herself, Her heirs and successors, give and grant unto
me, the, said, Moritz Jacoby, Her special licence that I, the said Moritz
Jacoby, my executors, administrators, and assigns, or such others, as I,
the said Moritz Jacoby, my executors, 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 "IMPROVE-
MENTS IN THE MANUFACTURE OF TWIST LACE IN TWIST LACE OR BOBBIN NET
MACHINERY," upon the condition (amongst others) that I, the said Moritz

page_text: .
Jacoby, my executors or administrators, by an instrument in writing under
my, 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 I, the said Moritz Jacoby, do hereby declare
the nature of the said Invention, and in what manner the sanie is to be
performed, to be particularly described and ascertained in and by the fol-
lowing statement thereof, that is to say :-
This Invention has for its object iniprovements in the manufacture of twist
Jace in twist lace or bobbin net machinery, and consists in producing a peculiar
combination of meshes, weavings, and edges or heads, with a view to obtain
better imitations by twist lace machinery of the Valenciennes laces produced
on the pillow by hand. For these purposes the ground of each breadth of
lace is composed of meshes, the pillars and crossings of which are each
composed of two bobbin threads and two warp threads, which in the pillars are
plaited or worked together, and which in the weavings or finings in the body
of the lace are all caused to act as warp threads, and they are wefted or shot
by two or more extra independent warp threads in making each spot or piece
of weaving, which two or more warp threads are worked into the pillars of the
ground of the lace, though they may, if desired, be so worked as to admit of
being cut away between the succeeding spots or pieces of weavings, though in
place of the two or more extra warp threads two or more of the ordinary warp
threads might be used. The weaving in the body of the lace might also be
produced by one or more carriage threads, or may be by a carriage and warp
thread conjointly shooting through several independent warp threads, which
warp threads can be worked in the lace if the pattern admits it, or clipped off
where not wanted. But I make no claim to the production of the net and
weaving or fining separately, as above described, the peculiarity of my Inven-
tion consisting in combining such net and weaving or fining (in the body of
the lace) with what may be called Valenciennes edges or heads, such edges or
heads to consist in each case of several independent warp threads; which are
caused to be shot or wefted with one or more bobbin threads, or it may be
with a bobbin thread and an independent warp thread conjointly, the purls
being produced as heretofore.
In carrying out the Invention it is preferred to employ two bobbin or
carriage threads, which, in addition to wefting the extra warp threads forming
the edges, are also caused to twist with each other, as was 'fully described in

page_text: the Specification of a former Patent granted to myself, James Redgate, and
Joseph Stone, dated 7th June 1860. (No. 1406), but the wefting may be
performed with other threads, as above stated. By this combination an
article is produced by twist lace or bobbin net machinery very similar to
Valenciennes laces produced on pillow by hand.
In witness whereof, I, the said Moritz Jacoby, have hereunto set my
hand and seal, this Nineteenth day of February, in the year of our
Lord One thousand eight hundred and sixty-one.
MORITZ JACOBY.
