I, EDWARD COPE of Lenton Firs, Nottingham, Lace Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention has for its object a novel twist lace fabric.
Lace fabrics for use as curtains and for such like purposes are at present made
having in each pillar of the fabric a warp thread, a bobbin thread, and a spool thread,
which latter traverses three gates or passes to and fro over three pillars.
In such fabric as at present manufactured the spool thread cannot at all times be
tied into the intermediate pillar but is flush or floated over it, so that the spool thread
remains loose or unattached over a space double that of the interval between pillar and
pillar. This floating or flushing of the spool thread, which occurs on one side of the
fabric is a defect which it is the object of my invention to remove.
For this purpose 1 employ two warp threads in each pillar, one in front of and the
other behind the spool thread. The two warp threads move simultaneously, and the
carriage thread passes around them as if they were but a single thread but the spool
thread being between these two warp threads becomes attached and tied in at every
pillar, and the defect of flushing or Hoating over the pillar is removed.

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 has for its object a novel twist lace fabric.
--
Lace fabrics for use as curtains and for such like purposes are at present made
having in each pillar of the fabric a warp thread, a bobbin thread, and a spool thread,
which latter traverses three or more gates or passes to and fro over three or more
pillars.
In such fabric as at present manufactured the spool thread cannot at all times be
tied into the intermediate pillar or pillars but is flushed or floated over it, so that the
spool thread remains loose or unattached over a space at least double that of the
interval between pillar and pillar.
This floating
or flushing of the spool thread, which occurs on one side of the fabric,
is a defect which it is the object of my invention to remove.
For this purpose I employ two warp threads in each pillar, one in front of and the
other behind the spool thread. The two warp threads move simultaneously and the
carriage thread passes around them as if they were but a single thread but the spool
thread being between these two warp threads becomes attached and tied in at overy
pillar, and the defect of flushing or floating over the pillar is removed.
It will thus be understood that for producing the improved twist lace fabric the
machine is set up as heretofore but with an additional warp bar so placed that the
spool threads are between the two warp bars. The additional warp bar is threaded
in the same way as the original or ordinary warp bar and the two bars move together
at the same time and in the same way.
It will generally be convenient to employ two separate but similar cam wheels to
move the two warp bars but obviously one cam wheel may be made to serve the
purpose. The present invention is applicable to lace fabrics such as described in the
Specification of my former Patent No. 13216 in the year 1885 and to other lace
fabrics where otherwise the defect of flushing or floating would occur.
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 improved twist lace fabric consisting of straight pillars containing two warp
threads and a bobbin thread and also spool threads traversing or passing to and fro
between the straight pillars and past intermediate pillars and between the warp threads
which such pillars contain substantially as described.
