Improvements in the Manufacture of Corset and other Lace Goods.
RICHARD HOPCROFT of No. 8 Short Hill, Nottingham, Lace Manufacturer, do
hereby declare the nature of this invention to be as follows:-
My invention has for its object to produce lace with rows of holes and with
colored threads ribbon or tape laid in and out through the holes the threads being
woven through the eyelet holes by machinery, during the process of manufacture of
the lace, instead of being threaded through by hand, after the lace has been manu-
factured.
Figure 1 of the annexed drawings shows in diagram a piece of lace of this
description, the colored threads are marked a. At the upper end of the diagram the
lace is shown as it appears when these threads are drawn out of the holes in the
lace.
Figure 2 is a draft indicating the manner in which I work in the threads a in
the process of manufacture of the lace so that they may be threaded in and out
through the holes in the lace.
The figures on the face of this draft indicate the position in the machine of the bars
which carry certain of the threads; more especially their relative positions a higher
number being ever in front of a lower. The horizontal lines represent the threads in
connection with which the carriages and bobbins work and the vertical lines represent
the motions as figured in the margin. The front motion is when the bobbin and
carriage threads are in front of the warp threads and the back motion is the
reverse.
In the diagram the threads moving on the perpendicular lines are moving on the
front motion and the threads moving in the spaces between these lines are moving on
the back motion.
The ribbon threads a are marked 31 and carried by bars which are behind the bars
which carry the gimps forming the part of the fabric extending in front of the ribbon
threads which I shall call pillar A.
The upper part of the fabric which lies behind the ribbon threads which I call
pillar B is produced by the same gimps as pillar A and accordingly would naturally
be in front of the ribbon threads, consequently the latter have to be passed below that
part of the pillar on the back motion over other gimps forming the lower part of
pillar B, which are arranged at the back of the lacing threads; having passed over
these they are again moved up on the back notion and continued or repeated under
pillar A as before. The threads 58 and 59 which encircle the holes are in front of all
other threads in the band so that the ribbon threads after passing under pillar A have
to be passed over the encircling threads (which are higher numbered) at the left side
of pillar B in the following way. Thread 58 after working round the top side of
hole (, is moved down the upper left hand portion of pillar B, on the front motion and
continued to the right side of pillar B when it makes the upper portion of that side
and continues round the top of the hole D and so on. Thread 59 works round the
under side of the hole C moves up on the front motion 2 motions prior to 58 coming
down (as per diagram) and then down on the back motion below thread 58 and across
pillar B and then up on back motion (same as ribbon threads rise on) to centre of
band and down on front motion and round under side of hole D and repeats.

Improvements in the Manufacture of Corset and other Lace Goods.
I, RICHARD HOPCROFT, of No. 8 Short Hill, 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:
My invention has for its object to produce lace with rows of holes and with
coloured threads ribbon or tape laid in and out through the holes; the threads being
woven through the eyelet holes by machinery, during the process of manufacture of
the lace, instead of being threaded through by hand, after the lace has been manu-
factured.
Figure 1 of the drawings left with the provisional specification shows in diagram a
piece of lace of this description, the coloured threads are marked a.
At the upper
end of the diagram the lace is shown as it appears when these threads are drawn out
of the holes in the lace.
Figure 2 is a draft indicating the manner in which I work in the threads a in the
process of manufacture of the lace so that they may be threaded in and out through
the holes in the lace.
The figures on the face of this draft indicate the position in the machine of the bars
which carry certain of the threads; more especially their relative positions a higher
number being ever in front of a lower. The horizontal lines represent the threads
in connection with which the carriages and bobbins work and the vertical lines
represent the motions as figured in the margin. The front motion is when the
bobbin and carriage threads are in front of the warp threads and the back motion is
the reverse.
In the diagram the threads moving to rise or fall when on the perpendicular
lines are moving on the front motion and the threads moving in the spaces between
these lines are moving on the back motion.
The ribbon threads a are marked 31 and carried by bars which are behind the
bars which carry the gimps forming the part of the fabric extending in front of
the ribbon threads which 1 shall call pillar A.
The upper part of the fabric which lies behind the ribbon threads which I call
pillar B is produced by the same gimps as pillar A and accordingly would naturally
be in front of the ribbon threads, consequently the latter have to be passed below
that part of the pillar on the back motion over other gimps forming the lower part of
pillar B, which are arranged at the back of the lacing threads; having passed over
these they are again moved up on the back motion and continued or repeated
under pillar A as before. The threads 58 and 59 which encircle the holes are in
front of all other threads in the band so that the ribbon threads after passing under
pillar A have to be passed over the encircling threads (which are bigher numbered)
at the left side of the pillar B in the following way. Thread 58 after working
round the top side of hole C, is moved down the upper left hand portion of pillar B,
on the front motion and continued to the right side of pillar B when it makes the
upper portion of that side and continues round the top of the hole D and so on.
Thread 59 works round the underside of the hole C moves up on the front motion 2
motions prior to 58 coming down (as per diagram) and then down on the back motion
below thread 58 and across pillar B and then up on back motion (same as ribbon
threads rise on) to centre of band and down on front motion and round under side of
hole D and repeats.
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 :-
The manufacture substantially in the manner described of lace with rows of eyelet

page_text: holes and with coloured or other threads, ribbon or tape laid in and out through the
holes; such threads ribbon or tape being woven through the eyelet holes by the
machinery by which the lace is produced as herein set forth.
