PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Twist Lace, and in Apparatus
therefor.
I, EDWARD COPE, of New Basford, Nottingham, Lace Manufacturer, do hereby
declare the nature of this invention to be as follows:-
The machines I employ are in many respects similar to those now in use for the
production of twist lace fabrics. Thus they have jacks or interceptors, a bar or
bars carrying warp threads and one, two or more carrying spool threads which may
vary in thickness and colours.
The warp threads and spool threads may be jacquarded to produce a variety of
groundworks and other ornamental effects.
The spool or spool threads may either twist in and form part of the fabric or be
caused to lie loose and be clipped when taken off the machine.
The object of my invention is to make grounds or networks. of much finer mesh
than has heretofore been made on any given gauge.
To do this, I employ a guide bar or bars in which are threaded threads coming
from a warp beam or beams or from independent spools passed round a roller
covered with cloth, or other suitable material, which are caused to twist as desired
either on one pillar or either of the adjoining pillars or to remain stationary and
form independent threads in the ground work.
By suitably weighting these extra warp threads a finer mesh or network can be
made than has hitherto been made in combination or other curtain goods.
When the extra warp threads which go to form the fine ground are required
to make openworks or such like ornamental effects in addition to the fine ground
or network I employ a lever or levers actuated by a suitable cam, interceptors, and
jacquard.
The extra warp bar or bars may be actuated in the ordinary way by the aid of a
lever and ratchet wheel at the end of machine or a combination of the two may be
used in which case a ratchet wheel is mounted on a guide bar lever or guide bar
link, und independent action given thereto.

Improvements in the Manufacture of Twist Lace, and in Apparatus
therefor.
I, EDWARD COPE, of New Basford, Nottingham, Lace 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 :-
The machines employ are in many respects similar to those now in use for
the production of twist lace fabrics. Thus they have jacks or interceptors, a bar or
bars carrying warp threads and one, two or more carrying spool threads which may
vary in thickness and colours.

page_text: To produce a fine net ground in any part of the pattern the jacks or inter-
ceptors B take the position B: Figure 9 repeated 4 motions followed by the
position B3, 6 motions alternately but this can be varied by less or more motions
alternately producing finer or coarser net at will.
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 :-
1. Twist lace having a ground of net of smaller size than the gauge of the machine
substantially as described.
2. The method of producing twist lace with a ground of fine net substantially as
described with reference to Figures 1 to 8 of the drawings.
3. The method of producing twist lace with a ground of fine net substantially as
described with reference to Figures 9 to 12 of the drawings.
4. Twist lace machines substantially as described and shown in Figures 1 to 8 of
the drawings.
5. Twist lace machines substantially as described and shown in Figures 9 to 12
of the drawings.
Dated this 19th day of December 1894.
