Improvements in the Manufacture of Lace Fabrics on Twist Lace
Machines, and in the Means or Apparatus employed therein.
We JOHN SULLEY, Lace Manufacturer and SYLVESTER THOMAS KIRK,
Mechanic, both of Russell Street Works in the Town and County of the Town of
Nottingham, do hereby declare the nature of this invention to be as follows :—
This invention has for its object improvements in the manufacture of lace fabrics
on twist lace machines and in the wheels and cooperating parts employed therein,
so as to enable the operator to more readily produce on such twist Inco machines a
new combination or combinations of lace, that is to say a combination of raised
objects on the ordinary patterns of curtains and similar articles by employing novel
means for their production.
When lace of the description indicated heretofore has been made in the ordinary
way the nett or ground work has been produced on twist laco or other machines
then the work has been taken off and the pattern or raised objects have been put
on by Swiss or other embroidery machines.
In producing such fabrics according to our improvements we are enabled to make
on twist lace machines the nett or ground work and raised pattern or objects in
various thicknesses all at the same time.
In carrying out our improvements in the manufacture of lace fabrics on twist
lace machines in this manner, we employ say a twist lace machine of usual or
convenient construction, having three or more guido bara, one bar (which may be
called No. 1 bar) for use for ground work or ordinary patterns of clothwork, the
second bar (No. 2) for use for the raised objects which are to be woven on the top
of objects or pattern on No. 1 bar we also uso other bars for ground work or netts
of finer texture.
We use jacks or interceptors which we construct with projections at the back to
strengthen and keep them from twisting or closing together.
They are of such a length and strength that they are capable of intercepting
three or other number of bars of threads and of withstanding the pressure
consequent on traversing the jacks to twelve or more gaits. They are also of such
a thickness that threads pressing each side the jacks will be divided by one gait.
We also use two jacquards one arranged to give a full lift and the other a half
lift, or one jacquard with double lift may be employed which we work with double
or single action. We thread No. 1 bar according to the number of raised objects
required in the pattern the other bars wo thread according to the number of
bobbins employed in the machine.
By these means we attain complete control over all or any portion of the threads
for example when the threads are not required to make embossed or raised objects
they are not obliged to pillar but by the action of jacquard on certain motions of
the wheels they may remain loose or tie in as required, one or both bars may be
making cloth at the same time.

Improvements in the Manufacture of Lace Fabrics on Twist Lace
Machines, and in the Means or Apparatus employed therein.
We JOHN SULLEY, Lace Manufacturer, and SYLVESTER THOMAS KIRK,
Mechanic, both of Russell Street Works 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 has for its object a novel manufacture of lace fabrics on twist lace
machine, and wheels and cooperating parts employed therein, so as to enable the
operator to more readily produce on such twist laco machines a new combination
or combinations of lace, that is to say a combination of raised objects on the
ordinary patterns of curtains and other articles, by employing novel means for their
production.
When lace of this description indicated heretofore, has been made in the ordinary
way the net or ground work has been produced on twist lace or other machines then
the work has been taken off and the pattern or raised objects have been put on by
Swiss or other embroidery machines.
In producing such fabrics according to our improvements, we are enabled to
make on twist lace machines, the net or ground work, and raised patterns or objects
in various thicknesses all at the same time.
In carrying out our improvements in the manufacture of lace fabrics on twist
lace machines, in this manner we employ say a twist lace machine of usual or
convenient construction having two, three or more guide bars, one bar which may
be called No. 1 for use for ground work or ordinary patterns of clothwork.
The second bar (No. 2) for use for the raised objects which are to be woven on
the top of objects or patterns on No. 1 bar.
We also use other bare for ground work or nets of finer texture, when required
we uso specially constructed jacks or intercoptors which we construct of such a
length and thickness as will enable us to jack or intercept one or the whole of the
threads in the bars as desired.
We also use two jacquards one arranged to give a full lift, and the other a half
lift or one jacquard with double lifts may be employed which we work with double
or single action.
We thread No. 2 bar according to the number of raised objects required in the
pattorn the other bars we thread according to the number of bobbins employed in
the machine.
By those means we attain completo control over all or any portion of the threads
for example, when the threads are not required to make embossed or raised objects
they are not obliged to pillar, but by the action of jacquard on certain motions of
the wheels, they may remain loose or tie in as required. One or both bars may be
making cloth at the same time.

rises one gait.
Jacks are pressed through threads by cam Fig. 6, guide bar & falls three gaits,
guide bar & falls two gaits, carriages pass into the front combs with another
selection from jacquards, guide bar & rises two gaits, guide bar b' rises two gaits,
the jacks are then pressed in, warp bar b falls ono gait, guide bar 6³ rises 3 gaits,
guide bar 6' rises two gaits, and the full motion is completed.
The same motions are required in our second combination except bar b which we
use for ground work.
Wheels for operating the bar bare not shown in drawings as we use various cuta
of wheels for different grounds.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The method of and apparatus for effecting the production of raised objects on
the patterns of curtains and similar articles of lace on twist lace machinery
substantially as set forth.
