PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Lace Fabrics on Twist
Lace Machines.
I, EDWARD COPE, Lace Manufacturer, of New Basford, Nottingham, do hereby
declare the nature of this invention to be as follows:-
I use jacks or interceptors to produce open works when making what I call
double-cross, or other grounds made by two or more steel or other ground bars
having end movements given to them by suitably cut wheels or pattern surfaces at
the end of the machine, such wheels or pattern surfaces being actuated by tooth
and ratchet wheels or other appliances to produce various ground works in
combination with one or more spool bars for making ornamented cloth-work.

Improvements in the Manufacture of Lace Fabrics on Twist
Lace Machines.
I, EDWARD COPE, Lace Manufacturer, of New Basford, Nottingham, 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 has for its object improvements in the manufacture of lace fabrics
on twist lace machines.
The machines which I employ are similar to those now in use for the production
of curtain fabrics, they have jacks or interceptors, a bar carrying spool threads, a
bar carrying warp threads and two half bars carrying threads which produce a
single cross or a double cross. In my invention I am able to stop one or more of
those crosses off at pleasure.
The spool bar and warp bar work in the ordinary way and in each pillar there is
one spool thread, and one warp thread, and one bobbin thread, also, one of the
threads which makes the double or single cross, so there are four threads in
each pillar, with the bobbin these two bars produce the crosses single or double
and are worked by wheels at the end of machine.
In the annexed drawing
Figure 1 shows these bars with the carriages in position. No. 1 is the spool bar,
No. 2 is the first half bar, No. 3 is the second half bar, and No. 4 is the
warp bar.
Figure 2 shows the wheel which works the half bar No. 2 and Figure 3 is the
wheel which works the half bar No. 3. These wheels produce a single cross ground
fabric.
To produce a fabric with a double cross ground I substitute for the wheel
Figure 2 the wheel shown by Figure 5 and for the wheel Figure 3. I substitute the
wheel shown by Figure 6.
Figure 7 shows a specimen of the new fabric which I produce; it has a double
cross ground, in which by the operation of the jacquard and jacks crosses are
stopped off at intervals.

page_text: I am able to jacquard the crosses at my pleasure at the same time that I make
cloth work or open work from the spool bar in the ordinary way.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A lace fabric such as herein shown with cloth work and a single or double
cross ground in which crossings are stopped off substantially as described.
2. The manufacture of lace fabrics with cloth work and a single or double
cross ground by means of the wheels represented by the annexed drawings,
working in conjunction with jacks and jacquard and other apparatus substantially
as described.
