Year: 1868

page_text: LETTERS PATENT to William Brailsford and Joseph Gadsby, both
of the Town and County of the Town of Nottingham, Draughts-
men, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF
LACE MADE ON BOBBIN NET OR TWIST LACE MACHINES, AND IN THE
MACHINERY OR APPARATUS EMPLOYED THEREIN."
Sealed the 9th April 1869, and dated the 12th October 1868.
PROVISIONAL SPECIFICATION left by the said William Brailsford
and Joseph Gadsby at the Office of the Commissioners of Patents,
with their Petition, on the 12th October 1868.
We, WILLIAM BRAILSFORD and JOSEPH GADSBY, both of the Town
and County of the Town of Nottingham, Draughtsmen, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE MANU-
FACTURE OF LACE MADE ON BOBBIN NET OR TWIST LACE MACHINES, AND IN
THE MACHINERY OR APPARATUS EMPLOYED THEREIN," to be as follows:-
Our Invention consists in manufacturing on single tier machines
employed in the manufacture of bobbin net or twist lace an embroidered
traversed warp net, the pillars of which are each made with one bobbin

page_text: thread and one warp thread, while the crossings are made with two warp
threads, the warp threads traversing the width of the breadth being
made if desired to traverse, the whole width of the machine.
When
the warp threads arrive, at the extremities of the breadths the left-hand
back warp thread is place in the front and the right-hand front warp
thread is placed in the back when making right twist net, but when
we make reverse twist net the left-hand front warp thread is placed
in the back and the right-hand back warp thread is placed in the
front; thus we produce a perfect net with all the crossings bound
down in like manner to the hand-made Brussels lace.
The machinery or apparatus we employ to carry out our Invention
consists, firstly, of two open stump bars or their equivalents, having a
stump for each gate; secondly, we employ two other bars, one to push
the threads out of the front stump bar into the back stump bar, the
other bar to push the threads out of the back stump bar into the front
stump bar; we also employ two other bars or instruments, one to bring
the left-hand back warp threads into the front, the other instrument to
take the right-hand front warp threads into the back when making the
right twist, or vice versa when making the reverse twist; the required
number of warp threads being wound on each bobbin or spole, the
bobbins or spoles are then placed on an endless band, chain, or circular
disc made to revolve at the required rate of speed to produce the fabric.
We
propose to make other. meshes of fabric than the above described
with the machinery or apparatus herein mentioned.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Brailsford and Joseph Gadsby in the
Great Seal Patent Office on the 12th April 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
BRAILSFORD and JOSEPH GADSBY, both of the Town and County of
the Town of Nottingham, Draughtsmen, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent; bearing date the Twelfth 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 us, the said William Brailsford and Joseph Gadsby,

page_text: Her special licence that we, the said William Brailsford and Joseph
Gadsby, our executors, administrators, and assigns, or such others as we,
the said William Brailsford and Joseph Gadsby, our executors, adminis-
trators, 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 "IMPROVEMENTS IN THE
MANUFACTURE OF LACE MADE ON BOBBIN NET OR TWIST LACE MACHINES, AND
IN THE MACHINERY OR APPARATUS EMPLOYED THEREIN," upon the condition
(amongst others) that we, the said William Brailsford and Joseph
Gadsby, 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 William Brailsford and Joseph
Gadsby, 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 thereof, reference
being had to the accompanying Drawings and to the letters and figures
marked thereon, that is to say:-
Our Invention consists in manufacturing on single tier machines
employed in the manufacture of bobbin net or twist lace an embroidered
traverse warp net the pillars of which are each made with one bobbin
thread and one warp thread, while the crossings are made with two warp
threads, the warp threads traversing the width of the breadth; being made
and if desired to traverse the whole width of the machine. When the
warp threads arrive at the extremities of the breadths the left-hand
back warp thread is placed in the front and the right-hand front
warp thread is placed in the back; thus we proceed when making
right twist net; but when we are making reverse twist net the left-
hand front warp thread is placed in the back and the right-hand
back warp thread is placed in the front; thus we are enabled to produce
a perfect net with all the crossings bound down in like manner to that
of the hand-made "Brussels" lace.
The machinery or apparatus which we employ to carry out our

page_text: Invention consists, firstly, of two open stump bars or their equivalents
having a stump for each gate; secondly, we employ two other bars, one
to push the threads out of the front stump bar into the back stump
bar the other bar to push the threads out of the back stump bar
into the front stump bar; we also employ two other bars or instruments, 5
one to bring the left-hand back warp threads into the front, the other
bar or instrument to take the right-hand front warp threads into the
back when making the right twist, or vice versa when making the
reverse twist; the required number of warp threads being wound on
each bobbin or spool, the bobbins or spools are then placed on an 1
endless band, chain, or circular disc, which band, chain, or disc
is made to revolve at the required speed to produce the fabric.
We propose to make other meshes of fabric than the above described
with the machinery or apparatus herein mentioned.
Having thus stated the nature of the said Invention, we now proceed 1
more particularly to describe the manner of performing the same with
reference to the accompanying Drawings.
DESCRIPTION OF THE DRAWINGS.
In Figure 1, A is the back stump bar; B, the front stump bar; C,
the back pusher bar; D, the front pusher bar; E is the bar or instrument a
employed to bring the left-hand back warp thread to the front; H
is a plate employed to keep the warp threads divided at the left-hand
extremity of the breadth; I, I, are warp threads.
In Figure 2, A is the back stump bar; B is the front stump bar; O
is the back pusher bar; D, the front pusher bar; F is the bar or instrument
employed to take the right-hand front warp thread to the back; G is
a plate employed to keep the warp threads divided at the right-hand
extremity of the breadth; and I, I, are warp threads.
Figure 3 exhibits the back pusher bar C pushing the back warp
threads into the front stump bar.
Figure 4 shows the front pusher bar D pushing the front warp threads
into the back stump bar.
Figure 5 represents a plan of the back stump bar A.
Figure 6 exhibits a plan of the front stump bar B.

page_text: Figure 7 shows a plan of the plate H, and Figure 8 a plan of the
plate G.
Figure 9 represents an endless band with bobbins to contain the
warp threads.
In making other meshes of lace we propose acting upon the threads
by the employment of instruments known as selectors or jacks.
Having now described the nature of our said Invention, and in
what manner the same may be performed, we declare that we claim,-
First. The improved mode of manufacturing lace on bobbin net
or twist lace machines herein-before described.
Second. The arrangement and combination of parts constituting
the improved machinery or apparatus, substantially as above described.
In witness whereof, we, the said William Brailsford and Joseph
Gadsby, have hereunto set our hands and seals, this Tenth day of
April, in the year of our Lord One thousand eight hundred and
sixty-nine.
