Improvements in the Manufacture of Lace Fabrics and in Apparatus
employed therein.
We EDWARD ELSEY of Russell Street Works, Lace Manufacturer, and
SYLVESTER THOMAS KIRK of Gamble Street, Mechanic, both in the Town and
County of the Town of Nottingham do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in the manufacture of lace fabrics in twist.
lace machinery and in apparatus employed therein.
The object of the invention is to effect tapeing or threading of tape through
bands of lace fabrics under and over from front to back and thick-threading or
spotting on front and back faces of such fabrics. Thus, for example, when making
blinds or other fabrics, there are formed at their top or outer bands holes or spaces
arranged at desired distances apart for the tape to be threaded through for holding
or fastening the same as required which said holes have the tapes or bands
threaded through them according to the present practice after the fabric comes off
the machine.
According to our invention we employ mechanism by which we effect the
operation of threading the tape or other material through the holes during the
manufacture of the fabric on the machine.
In carrying out our invention we employ pickers or thread guides fastened on the
shaft underneath the front comb bar which may be worked by cam
apparatus as desired.
or other
At the required bands to be laced we cut slots in the guide bars to allow the bars
to traverse the requisite number of gaits and in the centre of the slot we cut
through the guide bars so as to allow the picker which carries the tape to pass
through the guide bars from the front to the back of the work in which it rides
until a portion of the hole is made and then the picker passes from the back to the
front the hole is completed and the necessary band is made. A portion of the hole
being made a picker thread or tape passes through the hole to the back of the
work and the hole is completed threading being effected through holes from back
to front of the work as required.
For making spotting and thick threading on front and back faces of lace fabrics,
we employ pickers or thread guides similar to those described for the lacing of
lace fabrics, the pickers are fastened on rod or shaft underneath the front comb
bar, we cut slots in guide bars for pickers to pass through, allowing guide bars to
traverse the requisite number of gaits; we cut through the top of bars into the
centre of the slot to enable the pickers to pass thread through the slot also through
the slit from the top of the bars to the centre of the slot, from the front of the bars
to the back.
In addition to the movement given for pressing the pickers through the slots
from front of the bars to the back thereof and the back to the front thereof,
the picker rod or shaft has a lateral or shogging motion which is operated by
wheels or cams.
When the pickers are pressed through the bars from front to back, they shog
two or more gaits as required passing over bobbin threads, tieing in for spots, or
thick threading on back face of work, to the required distance. These pickers are
pressed from back to front shogging two or more gaits tieing in with bobbin
threads.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Lace Fabrics and in Apparatus
employed therein.
We EDWARD ELSEY of Russell Street Works, Lace Manufacturer, and
SYLVESTER THOMAS KIRK of Gamble Street, Mechanic, both in the Town and
County of the Town of 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 relates to improvements in the manufacture of lace fabrics in
twist lace machinery and in apparatus employed therein.
The object of the invention is to effect tapeing or threading of tape through
bands of lace fabrics under and over from front to back and thick-threading or
spotting on front and back faces of such fabrics. Thus, for example, when

According to our invention we employ mechanism by which we effect the
operation of threading the tape or other material through the holes during the
manufacture of the fabric on the machine.
In carrying out our invention we employ pickers or thread guides fastened on the
shaft underneath the front comb bar which may be worked by cam or other
apparátus as desired.
At the required bands to be laced we cut slots in the guide bars to allow the
bars to traverse the requisite number of gaits and in the centre of the slot we cut
through the guide bars so as to allow the picker which carries the tape to pass
through the guide bars from the front to the back of the work in which it rides

being made a picker thread or tape passes through the hole to the back of the work
and the hole is completed threading being effected through holes from back to

For making spotting and thick threading on front and back faces of lace fabrics,
we employ pickers or thread guides similar to those described for the lacing of
lace fabrics, the pickers are fastened on rod or shaft underneath the front comb
bar, we cut slots in guide bars for pickers to pass through, allowing guide bars to

thick threading on back face of work, to the required distance. These pickers
are pressed from back to front shogging two or more gaits tieing in with bobbin

Spotting gimping or thick threading on front and back faces of lace fabric is
effected when picker threads pass from one side of the bars to the other.
DESCRIPTION OF THE DRAWINGS.
Figs. 1 & 2 represent sectional views of parts of machine arranged according to
our invention with the thread carrier shewn in the front combs, A indicating the front
of the machine and B the back thereof. In Fig. 1 the top carrier is in its forward
position whilst in Fig. 2 it is in the rearward position. indicates one of the
thread carriages, f' the front and back combs, f³ the bobbin thread, fa bobbin,
ffguide threads and f tape. a a' shewing two guide bars and guides,
bb pickers or tape carriers, k k represent the fabric bands taped as shewn by
dotted lines.
Fig. 3 is a front view of our tapeing and thick threading apparatus. d d¹ d² are
tape carriers, guide bar and guides. c c¹ c² shewing slots through bars, c³ spool
threads through guides. t shaft for movement of tape carriers.
Figs. 4 & 5 shew by front and end views one of the thread carriers d d¹ d².
Fig. 6 is an end view of the guide h.
Fig. 7 is an end view of the guide h cut through the slot c c¹ c².

The guide bar h has guides set out according to the gauge of the machine, but
separately considered it is of the ordinary description. These guides have small
holes through them for the spool threads e³ to pass through and these threads
traverse from right to left as many gaits as may be required for making cloth or
open work.
In carrying out the invention which relates to tapeing and thick threading on
front and back of lace fabrics for example when making blind or curtain fabric the
outer edges are made with bands with holes at any required motions for the
threading of tape from front to back shewn by dotted lines (which has
according to present practice to be threaded by hand when the fabric comes off the
machine); our invention enables us to tape or thick-thread the fabric at the time
that it is made.
Fig. 3 is a front view shewing picker d, guide bar h, moved to the right in
slot c, d shewing picker in centre of slot for tape passing through, shewn by
dotted lines d², shewing guide bar moved to the left in slot c.
In carrying out our invention we provide guide bars hh' a a¹ with slots cut
through ca a' which enables us to pass tape carriers bb¹ (Figs. 1 & 2)
through slots cc c² a a¹ from front to back of lace fabric indicated by bb.
C
When making fabric band for lacing, say, every 14 motions the guide bar h
traverses from right to left three or four gaits making cloth, then jacks, not shewn,
are passed through threads which stop them from traversing, making holes, then
tape carrier passes through slot c' from front to back, then repeated 14 motions,
jacks come in making holes then tape guide 6 passes through the slot from back to
front, tape passing through holes of band from front to back & back to front every
14 motions indicated by dotted lines k k'.
Having now particularly described & ascertained the nature of our said inven-
tion & in what manner the same is to be performed, we declare that what we
claim is :-
1. The improvements in the manufacture of lace fabrics for effecting tapeing,
spotting, gimping or thick threading (separately or combined) thereof in twist lace
machinery during manufacture substantially as hereinbefore set forth.
2. The methods of and apparatus for the manufacture in twist lace machinery of

page_text: lace fabrics taped or threaded with tape, spotted, gimped or thick threaded
(separately or in combination) during manufacture as set forth.
