Improved Manufacture of Lace.
I, EMILE DAVENIERE of Rue Lafayette, Calais, Nord, France, Manufacturer, do
hereby declare the nature of this invention to he as follows:-
My invention relates to an improved manufacture of lace on ordinary
Leavers Machines having for its object to produce the lace in a more economical
manner by obtaining double the production per "rack" (corresponding to
1920 revolutions of the machine) as compared with the production heretofore
obtained, while maintaining the same quality.
The texture of my improved lace fabrics is distinguished from that of such fabrics
her-tofore produced, by the new mode in which the threads are interlaced, and by
the manner in which they are made to twist together and untwist.
The combination of the working of the warp threads, the bobbin threads, the
consolidating thread, (when used) and sometimes the weft threads (when used)
enable me to produce at the same time and at will a variety of combined effects,
such as ground, open work, pillars &c. In order to enable my invention to be readily
understood, I will describe the same with reference to the accompanying drawings
which shew a variety of different modes of producing the improved lace fabric.
On Sheet I of the drawing Figure 1 shews a diagrain of the operation for producing
a ground with warp threads, bobbin threads and a jacquarded consolidating thread.
In this and all the other diagrams, A' A2 &c. represent the bobbin threads, 3 and
4 are the consolidating threads; 6 and 7 the front warp threads, and 1 and 2 the
back warp threads, the width of the diagram represents two motions as indicated by the

Improved Manufacture of Lace.
I, EMILE DAVENIERE of Rue Layfayette, Calais, Nord, France, Manufacturer, do
hereby declare the nature of this invention and in what inanner the saine is to be
performed to be particularly described and ascertained in and by the following
statement:-
My invention relates to an improved manufacture of. lace on ordinary
Leavers Machines having for its object to produce the lace in a more economical
nanner by obtaining double the production per "rack" (corresponding to
1920 revolutions of the machine) as compared with the production heretofore
obtained, while maintaining the same quality..
The texture of my improved lace fabrics is distinguished from that of such fabrics
heretofore produced, by the new mode in which the threads are interlaced, and by
'the manner in which they are inade to twist together and unt ist.
The combination of the working of the warp threads, the bobbin threads,
the consolidating threads, (when used) and sometimes the weft threads
(when used) enable me to produce at the same time and at will a variety of combined

production, per "rack," than heretofore, and having ground, openwork and pillars
with repeats of three or six openwork portions.
2. The herein described new method of manufacture of lace upon the ordinary
Leaver machines by means of the combination of warp threads, bobbin threads,
consolidating threads, and weft threads or of warp threads, bobbin threads and

page_text: consolidating threads, or of warp threads, bobbin threads and weft threads, or of
warp threads, and bobbin threads only.
