1, ISAAC ELLIOTT of Liddington Street, New Basford, Nottingham, Lace
Draughtsman, do hereby declare the nature of this invention to be as follows
:-
My invention has for its object the production of twist lace fabrics on twist lace
machines in imitation of hand made lace in which a spot or other object is composed
of a number of pairs of threads crossing other pairs of threads.
This I effect by employing pairs of threads, each pair consisting of a bobbin thread
and a beam thread, for this purpose I employ the requisite number of pairs of threads,
the beam threads of which are caused to cross each other from one side of the spot or
other object to the centre, and then to return in like manner to their original position,
the bobbin threads being dominated by the beam threads are also caused to cross
each other in like manner to opposite sides of the spot or other object.
The beam threads are acted upon by perforated bars in the usual way, or spool
threads may be substituted for the beam threads, and be acted upon by perforated
bars or their equivalent.
I am thus enabled to produce machine made lace resembling hand made pillow
lace.

page_text: 1 ISAAC ELLIOTT of Liddington Street, New Basford, Nottingham, Lace
Draughtsman 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 :-
My Invention has for its object the production on twist lace machines of twist lace
fabrics, containing an imitation of a certain object, which has heretofore only been
produced on hand made lace, (chiefly torchon lace) and which is known as a torchon
spot.
This spot as made by hand is usually composed of an equal number of pairs of
threads, for example we will say 10 pairs, dividing them into two lots, five pairs
starting from the left hand side are caused to cross to the right hand, and the five
pairs of threads from the right hand side are likewise caused to cross to the left hand
side and in the act of crossing each thread is made to pass under and over every
alternate thread thus producing a perfect matting or weaving, when half the spot has
been made the threads again recross each other in a similar manner thus forming a
perfect spot.
In machine made lace this effect has hitherto been deemed impossible owing to the
action of the carriage threads, which do not traverse as the bean threads do.
Now in my improvements I by a novel arrangement and movement of beam
threads, (as shown at figure I and again at Figure 2, by numbers in the usual way.)
cause the said beam threads which while in the act of passing from the left hand to
the right, and from the right hand to the left to be continually catching and
dominating the carriage threads in such manner that in the finished spot shown at,
Figure 3, the carriage threads also appear to have traversed parallel with the beam
threads, from one side of the spot to the other. The method by which the beam
threads are operated in the machine will be clearly understood by referring to the
drawings. Figure 3 shows a finished spot as made on a twist lace machine by my
improvement. This spot is composed of ten pairs of threads, each pair containing a
carriage thread and a beam thread. The beam threads numbers 1b, 26, 36, 46, 5 b,
we will call the back threads, those numbered 6b, 76, 86, 96, 106 we will call the
front threads, now in the movement of threads as shown in Figure 1, the four
carriage threads marked 6c, 7 c, 8 c, 9c, being dominated by the beam threads are
brought over those marked 1c, 2 c, 3c, 4 c, 5c, at the same time, that is during the
working of the beam threads, the carriage threads marked 1 c, 2 c, 3c, 4 c, are caused
to pass under those from the opposite side of the spot, numbers 5 and 10 beam
threads being so worked that they and their corresponding carriage threads numbers 1
and 10, may form a hole in the centre of the spot, or otherwise.
When I speak of "beam threads" it is my intention to include "spool threads"
worked in the manner described in respect to the beam threads in Figure 1, and which
are actuated by perforated bars or their equivalent, also when I speak of a
"beam

page_text: thread" and "a carriage thread" to each pair of threads I mean that more threads
may be used in either case if necessary, neither do I confine myself to ten carriage
threads or ten beam threads to produce a spot, or other object, as obviously more or
less may in like manner be employed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I do not claim generally
causing a beam thread to catch a bobbin or carriage thread, thereby causing the
carriage thread to deviate from its original position, but what 1 do claim is,
The production on twist lace machines of lace having spots or other objects
composed of a number of pairs of threads from the left hand side crossing a similar
number of pairs of threads proceeding from the right hand side each pair containing
a bobbin thread or threads and a beam thread or threads, and which during crossing
cach pair is caused to interweave with opposite pairs of threads substantially as
described, and illustrated in the Drawings annexed.
