I, EMILE DAVENIÈRE, of Calais, France; Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to an improved manufacture of woven fabrics on lace-
machines known as "Leavers" machines, which fabrics have a texture similar to
those obtained on weaving looms, and which may have open work or embroidery
formed therein.
The fabrics are produced by four sets of threads namely "weft threads," "fixing
threads," "consolidating threads," and "bobbin threads." By means of these threads
a variety of different textures may be produced, either with or without open work.
For enabling this improved manufacture to be readily understood I have shewn on
the accompanying drawings seven combinations allowing the production of several
kinds of fabrics, and also seven examples shewing the positions that the threads take
in the fabric.
Figs. 1 and 2 shew a draught of two threads per bobbin thread, namely one weft
thread and one fixing thread.
The weft thread No. 4 travels two gates, connects to the threads of bobbins 1 and 2
in passing beneath them when rising and over them when falling. The weft thread
No. 1 travels two gates and connects with the bobbin threads 2 and 3 in passing
under them when rising and over them when falling.
The fixing thread No. 3 is to the right of bobbin thread 1, under weft thread 4;
it travels one gate displaces to the left in passing under bobbin thread 1 when falling
and rising; it thus avoids the weft thread 4, passing over the weft thread 1, so that
the fixing thread 3 is placed above the weft thread 4.
The fixing thread No. 2 is to the right of bobbin thread 2 above weft thread 1,
travels 1 gate, displaces to the left below the bobbin thread 2 in falling and rising ;
it is below weft thread 4 avoiding weft thread 1 so that the fixing thread 2 places
itself below weft thread 1.

rising, avoids weft thread 4 in passing over thread 1 so that the fixing thread 3 places
itself above weft thread 4. The fixing thread No. 2 is to the left of bobbin thread 2,
below weft thread 4, avoids weft thread 1 so that the fixing thread 2 places itself
below the weft thread 1, travels one gate and is to the right beneath bobbin thread 2
in rising and in falling above the weft thread 1. Fig: 4 shews the position of the
threads when the work of Fig. 3 is finished.

thread 6, it travels one gate, displaces to the left, passes above the bobbin thread 1 in
falling and in rising; it avoids the weft thread 6 in passing below weft thread 1 and
above fixing thread 4, so that the fixing thread 5 places itself above weft thread 6 and
to the right of fixing thread 4.
The fixing thread 4 is to the left of bobbin thread 1, above weft thread 1; it travels
one gate, displaces to the right, passing above the bobbin thread 1 in rising and in
falling, places itself beneath fixing thread 5 and beneath weft thread 6, so that fixing
thread 4 is below weft thread 6 and to the left of fixing thread 5.
The fixing thread No. 2 is to the right of bobbin thread 2, above weft thread 1; it
travels one gate, displaces to the left beneath bobbin thread 2 in falling and in rising,
beneath weft thread 6 and fixing thread 3, so that, according to its number, fixing
thread 2 is situated to the right of fixing thread 3.
The fixing thread No. 3 is to the left of bobbin thread 2, below the weft thread 6;
it travels one gate, displaces to the right beneath the bobbin 2 in rising and in falling
above the fixing thread 2 and the weft thread 1, so that, according to its number,
fixing thread 3 is placed to the left of fixing thread 2.

I, EMILE DAVENIÈRE, of Calais, France, Manufacturer, do hereby declare the nature
of this invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention relates to an improved manufacture of woven fabrics on lace machines
known as "Leavers" machines, which fabrics have a texture similar to those obtained
on weaving looms, and which may have open work or embroidery formed therein.
The fabrics are produced by four sets of threads, namely, "weft threads," "fixing
threads,"
," "eonsolidating threads" and "bobbin threads." By means of these threads
a variety of different textures may be produced, either with or without open work.
For enabling this improved manufacture to be readily understood, I have shewn
on the drawings accompanying my Provisional Specification seven combinations
allowing the production of several kinds of fabrics, and also seven examples shewing
the positions that the threads take in the fabric.

The consolidating threads are employed for imparting strength to the tissue.
The fixing thread No. 5 is to the right of bobbin thread 1, below the weft thread 6,
it travels one gate, displaces to the left, passes over bobbin thread 1, consolidating
thread 4 and weft thread 1 when falling and rising, it avoids the weft thread 6, so
that the fixing thread 5 places itself above the weft thread 6.
The fixing thread No. 2 is to the left of bobbin thread 2, below the weft thread 6,

page_text: avoids weft thread 1, travels one gate, displaces to the right below the bobbin thread 2
when rising and when falling; it places itself below the consolidating thread 3 and
above the weft thread 1, so that the fixing thread 2 is situated below the weft thread 1.
Fig. 12 shews the positions of the threads after the work is completed, Figs. 13
and 14 shew a draught of three threads per bobbin, namely one weft thread and two
fixing threads.
The weft thread No. 6 travels two gates, connects the bobbin threads 1 and 2 in
passing beneath when rising and above when falling. The weft thread No. 1 travels
two gates, connects bobbin threads 2 and 3 in passing beneath when rising and above
when falling. The fixing thread No. 4 is to the right of bobbin thread 1, beneath weft
thread 6, travels one gate, displaces to the left in passing above the bobbin thread
when falling and when rising, thus avoids the weft thread 6 in passing above the
fixing thread 2 and the weft thread 1 so as to place itself above the weft thread 6 and
to the left of the fixing thread 5.
The fixing thread No. 5 is to the left of bobbin thread 2, below the weft
thread 6, travels one gate, displaces to the right in passing above the bobbin thread 2
when rising and falling, thus avoiding the weft thread 6 in passing above the fixing
thread 3 and the weft thread 1, so as to place itself above the weft thread 6 and to the
right of fixing thread 4. The fixing thread No. 3 is to the left of bobbin thread 2,
below the weft thread 6 and the fixing thread 5, avoids the weft thread 1 so as to place
itself below the weft thread 1 and to the right of fixing thread 2; it travels one gate,
is situated to the right below the bobbin thread 2 when rising and falling and above
the weft thread 1.
The fixing thread 2 is to the right of bobbin thread 3, above the weft thread 1,
below the fixing thread 4, travels one gate, displaces to the right, passes beneath the
bobbin thread 3 both when rising and falling, avoids the weft thread 1, in passing
below the weft thread 6 so as to place itself to the right of fixing thread 3.
Fig. 14 shews the position of the threads when the work is completed; Figs. 15
and 16 shew a draught for open work with three threads per bobbin, namely one weft
thread and two fixing threads. For obtaining open work effects it is sufficient to
cause the weft threads 6 and 1 to work first over two bobbin threads and then over
only one either to the left or to the right.
Fixing thread 4 is to the left of bobbin thread 1, travels one gate, displaces to the
right in passing above the bobbin thread 1 when falling, and when rising, passes
above weft thread 1 and fixing thread 2, avoids weft thread 6 so as to place itself
above and to the right of fixing thread 5, displaces itself to the left above bobbin
thread when falling and below when rising.
The fixing thread No. 5 is to the right of bobbin thread 2 below the weft thread 6,
travels one gate, displaces to the left in passing above bobbin thread 2 and fixing
thread 3, both when rising and falling, avoids the weft thread 6 so as to place itself
above and to the left of fixing thread 4, is then situated below weft thread 6, displaces
to the right below the bobbin thread when rising and above when falling.
The fixing thread No. 3 is to the right of bobbin thread 2, travels one gate, displaces
to the left in passing above the bobbin thread and below the fixing thread places
itself to the right below the bobbin thread 1 and above the weft thread 1, passes to
the left below the bobbin thread 2 when falling and rising below the fixing thread 5
and the weft thread 6, avoiding the weft thread 1. The fixing thread 2 is to the left
of bobbin thread 3, travels one gate, displaces to the right in passing above the bobbin
thread 3 and below the fixing thread 4, passes above the bobbin thread 3 in falling,
above the weft thread 1, below the bobbin thread 3 when rising and falling, avoiding
thus weft thread 1.

Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :
The manufacture of fabric similar to woven fabric, which may have open or
embroidered work, by the use on a Leaver's lace machine of weft, fixing consolidating
and bobbin threads, substantially as herein described.
Dated this 27th day of September 1887.
