CHARLES DENTON ABEL of No 28 Southampton Buildings, Chancery Lane, in
the County of Middlesex "AN IMPROVED MANUFACTURE OF LACE" [communi-
cated to him from Abroad by Emile Davenière of Paris in the French Republic]
This invention relates to an improved manufacture of lace which is distinguished
from lace heretofore made on "Leavers" machines in having a peculiarly brilliant
appearance similar to satin, analogous to the effect produced by pusher niachines.
The improved manufacture of lace is produced on ordinary "Leavers" machines,
the said brilliant effects of certain parts thereof being obtained by a combination of
bobbin and warp threads, such, that floated bobbin threads are made to cover or
hide the connections of the bobbin and warp threads, these floated threads being
made to impart the said satin like appearance to the fabric.
In the ordinary working of a "Leavers" machine, the thread generally travels
from one carriage to the next when the openings or meshes have to be filled up.
According to the present system the bobbin thread is floated over the intervals of
several carriages, whereby the brilliant effect is obtained, and it is this arrangement
which forms the essential feature of the new manufacture.
In order that the invention may be readily understood, several combinations are
shewn on the accompanying drawing, whereby the said brilliant effect may be
produced, the vertical lines representing the warp threads, and the oblique lines
the bobbin threads. Fig. 1 shews an arrangement in which there are two warp
threads for each carriage, the warp thread No 1 travelling 3 gates and connecting
to bobbin thread N° 3 in rising aud to bobbin thread N° 1 in falling, and passing
under the bobbin Nº 2 in rising and falling, which causes the bobbin thread N° ?

travelling together 4 gates and interlacing with the bobbin threads 1, 2, 3, 4 in

may also be used with one warp thread for each carriage.
In Fig. 4 there are two warp threads to each carriage, both threads travelling
together three-gates and interlacing with bobbin thread N° 3 in rising and with
No 1 in falling, whereby bobbin thread N° 2 is made to float over the warp
tbread No 1-in rising and fulling and thus hides the connections of the the bobbin
threads with the warp threads.

CHARLES DENTON ABEL of N° 28 Southampton Buildings Chancery Lane in
the County of Middlesex AN IMPROVED MANUFACTURE OF LACE a communi-
cation to me from Abroad by Emile Davenière of Paris in the French Republic
This invention relates to an improved manufacture of laco which is distinguised
from lace heretofore made on "Leavers" machines in having a peculiarly brilliant
appearance similar to satin analogous to the effect produced by pusher machines.
The improved manufacture of lace is produced on ordinary "Leavers" machines,
the said brilliant effects of certain parts thereof being obtained by a combination
of bobbin and warp threads, such, that floated bobbin threads are made to cover or
hide the connections of the bobbin and warp threads, these floated threads being
made to impart the said satin like appearance to the fabric.
In the ordinary working of a "Leavers " machine, the thread generally travels from
one carriage to the next when the openings or meshes are to be filled up. According
to the present system, the bobbin thread is floated over the intervals of several
carriages either with or without intermediate attachments, whereby the brilliant
effect is obtained, and it is this arrangement which forms the essential feature of
the new manufacture.
In order that the invention may be readily understood, several combinations are
shewn on the accompanying drawing, whereby the said brilliant effect may be
produced, the vertical lines representing the warp threads, and the oblique lines the
bobbin threads. Fig. 1 shews an arrangement in which there are two warp threads
for each carriage, the warp thread N° 1 travelling 3 gates and connecting to
bobbin thread N° 3 in rising and to bobbin thread N° 1 in falling, and passing
under the bobbin N° 2 in rising and falling, which causes the bobbin thread N° 2
in floating over thread No 1 in rising and falling to hide the connections with the
warp thread N° 1. Warp thread N° 2 travelling 2 gates, interlaces with bobbin
threads No 3 and No 2 in rising and falling, the interlacing of the warp thread N° 2
allowing the fabric to remain smooth and regular. Fig. 2 shews an arrangement
in which there are two warp threads for each carriage, the warp thread N° 1
travelling 4 gates and interlacing with bobbin threads 1, 2, 3, 4 in rising and
falling, while warp thread N° 2 travelling 3 gates and avoiding the first bobbin
thread, passes beneath the bobbin threads 2 and 3 and over the bobbin thread 4 in
rising, and beneath the bobbin threads 3 and 4 and over 2 in falling, whereby the
bobbin thread 3 in floating, in rising and falling, hides the connections formed by
the warp thread N° 1.
At Fig. 3 there are two warp threads for each carriage, warp threads 1 and 2
travelling together 4 gates and interlacing with the bobbin threads 1, 2, 3, 4 in
rising and falling, whereby the fabric is formed without a back. This arrangement
may also be used with one warp thread for each carriage.
In Fig. 4 there are two warp threads to each carriage, both threads travelling
together three gates and interlacing with bobbin thread N° 3 in rising and with
No 1 in falling, whereby bobbin thread N° 2 is made to float over the warp thread
No 1 in rising and falling, and thus hides the connections of the bobbin threads
with the warp threads.
Having thus described the nature of this invention and in what manner the
same is to be performed as communicated to me by my foreign correspondent, I
claim-
First. The herein described improved manufacture of lace on "Leavers" machines,
wherein a brilliant or satin like appearance is obtained by causing certain of the

page_text: bobbin threads to be floated so as to hide the connections between the other bobbin
threads and the warp threads.
Second. In the manufacture of lace on "Leavers" machines, referred to in the
preceding claim, the method of causing the bobbin threads. to float at will over
the interval of several carriages, according to the design to be produced, substan-
tially as herein described.
In Witness whereof I the said Charles Denton Abel have hereunto set my hand
and seal this Fourteenth day of February in the year of our Lord One thousand
eight hundred and eighty-four.
