PROVISIONAL SPECIFICATION left by the said Thomas Wright and Isaac
Fox at the Office of the Commissioners of Patents on the 1st September
1877.
THOMAS WRIGHT and ISAAC Fox, both of the Town and County of the Town of
Nottingham, Lace Manufacturers, "IMPROVEMENTS IN THE MANUFACTURE OF
FABRICS IN TWIST LACE MACHINERY."
This Invention has for its object improvements in the manufacture of fabrics in
twist lace machinery, and relates to improved production of weaving in connection,
or not, with other classes of fabric.
For this purpose we employ various combinations of warp and bobbin threads,
using some of the warp threads as "corders," and others as traversing threads, and
causing the traversing threads to traverse any desired and convenient number of
gaits" in the one direction and then in the other, and causing them to be bound
or united with the "corders" and bobbin threads by the twisting together of the
bobbin threads and "corders."
"
In some cases we dispense with the "corders" and employ only bobbin threads
and traversing threads to weave together. We arrange the traversing threads in
groups to weave bands of any desired width, or we arrange them in regular suc-
cession across the width of the fabric to produce weaving of any desired width, or
a number of bands may be joined together to produce any desired width of fabric.
Thus, supposing the traversing threads are caused to cover eight carriages we use
sixteen bars and traversing threads, and we reduce or increase the number of bars
and traversing threads by two for each carriage, less or more, over which such
Price &d71

page_text: traversing threads are caused to work; and where it is desired to produce a more
solid fabric we use a double quantity of traversing threads, arranged in two sets,
one set to work in the front and the other at the back of "corders," the one set
moving one motion after the other set, the "corders" being by preference placed
between the two sets of traversing threads.
In producing weaving according to the arrangements last above described the
individual threads of each set of traversing threads move two motions after each
other, and as one set moves intermediate of the other set a traversing thread is
caused to act in combination with and be connected to each bobbin thread at every
motion of the machine.
In some cases we employ four or more traversing threads to work from one
carriage to the next and back again, using a number of motions proportionate to
the number of traversing threads, causing such threads to follow each other at
every motion of the machine. In this arrangement "corders" may or may not be
used, as most desirable.
In some cases we move each traversing thread one motion after another across
two carriages, working as one, at each extremity of such thread's action, using
'corders" or not.
"
Our improved weaving can be produced in different patterns, according as the
bars and threads are arranged, and can be made in different widths and thicknesses
to suit various purposes, whilst it can be produced in combination with other classes
of fabric as may be desired.
Our improved fabric may be embroidered or ornamented by the aid of additional
threads, as is well understood; or open-work can be made in connection with it.

THOMAS WRIGHT and ISAAC Fox, both of the Town and County of the Town of
Nottingham, Lace Manufacturers. "IMPROVEMENTS IN THE MANUFACTURE OF
FABRICS IN TWIST LACE MACHINERY."
This Invention has for its object improvements in the manufacture of fabrics in
twist lace machinery, and relates to improved production of weaving in connection,
or not, with other classes of fabric.
For this purpose we employ various combinations of warp and bobbin threads,
using some of the warp threads as corders, and others as traversing threads, and
causing the traversing threads to traverse any desired and convenient number of
'gaits" in the one direction and then in the other, and causing them to be bound
or united with the "corders" and bobbin threads by the twisting together of the
bobbin threads and "corders."

In some cases we dispense with the "corders" and employ only bobbin threads
and traversing threads to weave together. We arrange the traversing threads in
groups to weave bands of any desired width, or we arrange them in regular suc-
cession across the width of the fabric to produce weaving of any desired width, or a
number of bands may be joined together to produce any desired width of fabric.
Thus, supposing the traversing threads are caused to cover eight carriages, we use
sixteen bars and traversing threads, and we reduce or increase the number of bars
and traversing threads by two for each carriage, less or more, over which such
traversing threads are caused to work; and where it is desired to produce a more
solid fabric we use a double quantity of traversing threads, arranged in two sets,
one set to work in the front and the other at the back of "corders," the one set
moving one motion after the other set, the "corders" being by preference placed
between the two sets of traversing threads.
In producing weaving according to the arrangement last above described the
individual threads of each set of traversing threads move two motions after each
other, and as the one set moves intermediate of the other set a traversing thread is
caused to act in combination with and be connected to each bobbin thread at every
motion of the machine.
In some cases we employ four or more traversing threads to work from one
carriage to the next, and back again, using a number of motions proportionate to
the number of traversing threads, causing such threads to follow each other at every
motion of the machine. In this arrangement "corders" may or may not be used
as most desirable.
In some cases we move each traversing thread one motion after another across
two carriages, working as one, at each extremity of such thread's action, using
"corders" or not.
Our improved weaving can be produced in different patterns, according as the
bars and threads are arranged, and can be made in different widths and thicknesses
to suit various purposes, whilst it can be produced in combination with other classes
of fabric, as may be desired.
Our improved fabric may be embroidered or ornamented by the aid of additional
threads, as is well understood; or open work can be made in connection with it.
And in order that our Invention may be more clearly understood we will proceed
to describe some examples of the mode in which we carry the same into effect.
We will now describe the arrangement of bars and threads for a band of weaving
covering eight carriages, counting the bars in the machine as the back bar being
No. 1. We take the first eight bars and use them one to a carriage as corders, .
twisting every motion of the machine one gait, as is understood by any lace
draughtsman. We then take the next sixteen bars, all being at the samo dead
stop, and move the first bar from dead stop up one gait on the front motion; we

page_text: move it up one more gait the next front motion, and every front motion we move
one more gait till we have covered the whole of the eight carriages, and return
back as we went upwards by falling onė gait every front motion till we come to
dead stop. The second bar we move from dead stop two motions after No. 1 bar,
and No. 3 bar works just the same, only two motions later, and so on with the
whole sixteen bars, which just the number it will take to produce a band covering
eight carriages. It will take 4 bars to cover two carriages, and two extra for every
carriage added.
In some cases we use four warp threads to one bobbin thread, either with corders
or without them.
This method of weaving is also adapted for solid fabrics, such as towels, the
necessary thickness being obtained by using a double quantity of weaving threads,
one set in the front, and another set in the back, moving one motion after the front
ones. By this arrangement we can get a fine or coarse weaving, according to the
thickness of cotton we use, or the quality we work it up.
These arrangements of bars and threads can be varied and extended, according to
the extent or limit of the article or fabric we wish to manufacture.
Having thus described the nature of our said Invention, and the mode in which
we carry the same into effect, we would have it understood that what we claim is,
the production of a woven fabric, in conjunction or not with other fabrics, made on
lace machines, by means of a series of threads which traverse any required distance
backwards and forwards, one after another, at every motion, or two motions, of the
machine over one or more carriages or weft threads, another series of threads
traversing at the same time in a similar manner in an opposite direction; all of
which traversing threads are woven or bound together by the bobbin or weft
threads, with or without "corders," in manner substantially as herein described.
In witness whereof, we, the said Thomas Wright and Isaac Fox, have here-
unto set our hands and seals, this Twenty-seventh day of February, in the
year of our Lord One thousand eight hundred and seventy-eight.
