IN TWIST LACE MACHINES."
PROVISIONAL SPECIFICATION left by the said Aaron Mosley at the Office
of the Commissioners of Patents on the 18th October 1876.
AARON MOSLEY, of Southey Street, Forest Road, Nottingham, in the County of
Nottingham, Mechanic. "IMPROVEMENTS IN AND CONNECTED WITH TWIST LACE
MACHINES, AND IN A SPECIAL ARRANGEMENT OF THREADS FOR THE PRODUCTION OF
IMITATION GUIPURE' IN TWIST LACE MACHINES."
The Invention will be understood by the following:-I employ three guide bars,
a warp bar, a spool bar, or fancy bar, which are the usual bars used in a curtain
machine. The third guide bar is arranged in the front of the other two guide bars.
In the warp bar I arrange two kinds of threads in a particular way. The spool
bar or fancy bar is fitted with threads in the usual way. The third guide bar has
also a particular arrangement of threads. Two guide bars are acted upon in the
usual way by cams which cause the threads in the bars to move into position for
the jacks to intercept the threads, and then into position for the carriages to pass
through. The third guide bar is acted upon by a cam or wheel, or by a jacquard
having the required number of motions to produce two holes. The threads in the
third guide bar are not acted upon by the jacks, but are moved into the position
required by the cam wheel or jacquard.
For the main warp I use two kinds of threads which I will call fine and coarse
threads; the fine threads are wound upon one beam, and the coarse threads are
wound upon another bean, to enable me to put the required weight on each kind
of tlireads.
I will now describe the way the threads are arranged in the warp guide bar, the
third guide bar, and the fancy bar. I arrange the threads in the warp bar as
follows: In No. 1 guide I put a coarse thread; in 2nd and 3rd, fine threads; in
the 4th, a coarse thread; in 5th and 6th, fine threads; and so on until the required
Prins G21

page_text: number of threads are entered in the guides of the warp bar. The guide bar for
the fancying threads I fill in the usual way with threads equal in number to the
threads in the warp guide bar. The fancying threads are wound upon separate
spools as used by the trade. The third guide bar has only one-third the number of
guides used in the warp guide bar; the guides in this bar having one or two threads
as required through each guide. The threads in this guide bar are also wound
upon a separate beam and can be weighted as required.
By the particular arrangement of fine and coarse threads in the warp bar I can
use the coarse threads as foundation threads, using at the same time the fine threads
to make a fancy ground. The coarse threads have to bear a greater tension to tie
the other threads firmly together at the crossings of the coarse threads.
By operating upon these threads with jacks I can at pleasure either tie the fine
warp threads on each side, the coarse threads to the coarse threads, or tie the fine
threads which are between the coarse threads together. The threads in the third
guide bar not being acted upon by the jacks, move into positions that the wheel or
cam or jacquard may place then, to cause the threads in the guide bar to pass
over; the fine thread bobbins on each side of the coarse threads thereby causing
a straight tie across the warp threads at the top and bottom side of the hole or
mesh.
The threads in the spool or fancy bar are acted upon by the jacks in a similar
way to the threads in the warp bar, which enables me to use either thread at
pleasure to fill up any portion of a hole or any of the divisions made by the diagonal
worked threads that may be inside the square hole; at the same time I am able to
fill the hole up entirely or to leave the hole (mesh) quite open. It must be under-
stood that by the operation of the jacks on the threads all these motions can be
made at the same time.
I now describe the way the guide bars work, supposing the carriages to be at the
back. The warp guide bar is acted upon by its cam which causes the threads in the
bar to rise two gaits. The spool or fancy bar is acted upon by its cam and causes
The third
the threads in the bar to rise 4 gaits; the jacks then.enter the threads.
guide bar is acted upon at the same time as the warp bar by its cam, which causes
the threads in the bar to rise 2 gaits. The cams of the spool and warp bar again act
and cause the threads in the warp bar to rise one gait, and the threads in the spool
bar to rise three gaits, the carriages passing through the threads to the front of the
machine, and the points take up the work in the usual way. The carriages having
now gone from the back to the front of the machine, the jack bar rises one gait, the
cams again act upon the warp and spool bar and allow the warp bar to fall 3 gaits
and the spool bar to fall 7 gaits. The cam again acts upon the third guide bar and
allows the threads in the bar to fall 6 gaits for the carriages to again pass through
the threads into their former position at the back of the machine. The jack bar
falls one gait, and the points take up the work as before.
The warp bar and spool bar always rise the same number of gaits when the
carriages are in the back, and fall the same number of gaits when the carriages are in
the front of the machine. The jack bar always falls one gait when the carriages are
at the back, and rises one gait when the carriages are in the front of the machine.
The third guide bar, as described, rises two gaits when the carriages are in the
back, and falls 6 gaits when the carriages are in the front, then again rises
two gaits when the carriages are in the back, and falls one gait when the
carriages are in the front. This bar then rises one gait and falls one gait at
each movement of the carriages until the 17th motion. The carriages being then
in the back the bar falls one gait, the carriages pass to the front; the bar then rises
6 gaits, the carriages pass to the back; the bar then falls two gaits, the carriages
again pass to the front; the bar then rises one gait, and at the next motion falls
one gait. The bar then rises one gait and falls one gait at each movement of the
carriage until the 22nd motion, the carriages being then in the front of the machine.
The bar rests during this motion, and the carriages again pass to the back; the bar
then rises one gait and falls one gait as before at each movement of the carriages

page_text: until the 32nd motion. The wheel is then in the position as first described, having
caused the threads in the third guide bar to pass over the bobbins each side of the
thick threads, and then twist down the pillars to form a straight tice across the warp
threads.
One of the coarse threads in the warp bar may be carried by an additional guide
bar, the other thread being then carried as above described.
I have referred to the fancy bar as rising four gaits at one time, but the same
effect can be obtained by rising the bar or threads one gait first and then three
gaits, after which it would fall four gaits.
"
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said Aaron Mosley in the Great Seal Patent Office on the 16th April 1877.
AARON MOSLEY, of Southey Street, Forest Road, Nottingham, in the County of
Nottingham, Mechanic. "IMPROVEMENTS IN AND CONNECTED WITH TWIST LACE
MACHINES, AND IN A SPECIAL ARRANGEMENT OF THREADS FOR THE PRODUCTION OF
IMITATION GUIPURE' IN TWIST LACE MACHINES."
This Invention has for object improvements in and connected with twist lace
machines, and in a special arrangement of threads for the production of imitation
'Guipure" in twist lace machines.
The Invention will be clearly understood by the following description, in which
coarse and fine threads respectively are referred to-I employ three guide bars, a
warp bar, a spool bar, or fancy bar, which are the usual bars used in a curtain machine.
The third guide bar is arranged in the front of the other two guide bars. In the
warp bar I arrange two kinds of threads in a particular way. The spool bar or
fancy bar is filled with threads in the usual way. The third guide bar has also a
particular arrangement of threads. Two guide bars are acted upon in the usual way
by cams which cause the threads in the bars to move into position for the
jacks to intercept the threads, and then into position for the carriages to pass
through. The third guide bar is acted upon by a cam or wheel or by a jacquard
having the required number of motions to produce two holes. The threads in the
third guide bar are not acted upon by the jacks, but are moved into the positions
required by the can wheel or jacquard.
For the main warp I use two kinds of threads, which I will call fine and coarse
threads, the fine threads are wound upon one beam, and the coarse threads are
wound upon another beam, to enable me to put the required weight on each kind of
thread.
I will now describe the way the threads are arranged in the warp guide bar, the
third guide bar, and the fancy bar. I arrange the threads in the warp bar as follows:-
In No. 1 guide I put a coarse thread; in the second and the third, fine threads; in the
fourth, a coarse thread; in the fifth and sixth, fine threads, and so on until the
required number of threads are entered in the guides of the warp bar.
The guide
bar for the fancying threads I fill in the usual way with threads equal in number
to the threads in the warp guide bar. The fancying threads are wound upon
separate spools as used by the trade. The third guide bar has only one third the
number of guides used in the warp guide bar, the guides in this bar having one or
two threads as required through each guide. The threads in this guide bar are also
wound upon a separate beam and can be weighted as required.
By the particular arrangement of fine and coarse threads in the warp bar I can
use the coarse threads as foundation threads, using at the same time the fine threads
to make a fancy ground. The coarse threads have to bear a greater tension to tie
the other threads firmly together at the crossings of the coarse threads.
By operating upon these threads with jacks I can at pleasure either tie the fine
warp threads on each side the coarse threads to the coarse threads or tie the fine

page_text: threads, which are between the coarse threads, together. The threads in the third
guide bar not being acted upon by the jacks move into positions that the wheel or
cam or jacquard may place them to cause the threads in the third guide bar to pass
over the fine thread bobbins on each side of the coarse threads, thereby causing a
straight tie across the warp threads at the top and bottom side of the hole or mesh.
: The threads in the spool or fancy bar are acted upon by the jacks in a similar
way to the threads in the warp bar, which enables me to use either thread at
pleasure to fill up any portion of a hole or any of the divisions made by the
diagonal worked threads that may be inside the square hole, at the same time I am
able to fill the hole up entirely or to leave the hole (mesh) quite open. It must be
understood that by the operation of the jacks on the threads all these motions can
be made at the same time.
I now describe the way the guide bars work supposing the carriages to be in the
back. The warp guide bar is acted upon by its cam, which causes the threads in the
bar to rise two gaits. The spool or fancy bar is acted upon by its cam, and causes
the threads in the bar to rise four gaits, the jacks then enter the threads. The third
guide bar is acted upon at the same time as the warp bar by its cam, which causes
the threads in the bar to rise two gaits. The cams of the spool and warp bars again
act and cause the threads in the warp bar to rise one gait, and the threads in the
spool bar to rise three gaits, the carriages passing through the threads to the front of
the machine, and the points take up the work in the usual way. The carriages
having now gone from the back to the front of the machine, the jack bar rises one
gait, the cams again act upon the warp and spool bars, and allow the warp bar to
fall three gaits and the spool bar to fall seven gaits. The cam again acts upon the
third guide bar, and allows the threads in the bar to fall six gaits for the carriages
to again pass the threads into their former position at the back of the machine. The
jack bar falls one gait, and the points take up the work as before.
The warp bar and spool bar always rise the same number of gaits when the
carriages are in the back, and fall the same number of gaits when the carriages are
in the front of the machine. The jack bar always falls one gait when the
carriages are at the back, and rises one gait when the carriages are in the
front of the machine. The third guide bar as described rises two gaits when
the carriages are in the back, and falls six gaits when the carriages are in the
front, then again rises two gaits when the carriages are in the back, and falls one
gait when the carriages are in the front; this bar then rises one gait and falls one
gait at each movement of the carriages until the seventeenth motion. The carriages
being then in the back the bar falls one gait, the carriages pass to the front, the bar
then rises six gaits, the carriages pass to the back, the bar then falls two gaits, the
carriages again pass to the front, the bar then rises one gait, and at the next motion
falls one gait. The bar then rises one gait and falls one gait at each movement of
the carriage until the twenty-second motion, the carriages being then in the front
of the machine. The bar rests during this motion, and the carriages again pass to
the back, the bar then rises one gait and falls one gait as before at each movement
of the carriages until the thirty-second motion; the wheel is then in the position as
first described, having caused the threads in the third guide bar to pass over the
bobbins each side of the thick threads, and then twist down the pillars to form
a straight tie across the warp threads.
One of the coarse threads in the warp bar may be carried by an additional guide
bar, the other threads being carried as above described.
I have referred to the fancy bar as rising four gaits at one time, but the same
effect can be obtained by rising the bar or threads one gait first and then three
gaits, after which it would fall four gaits.

Nottingham, Mechanic. "IMPROVEMENTS IN AND CONNECTED WITH TWIST LACE
MACHINES, AND IN A SPECIAL ARRANGEMENT OF THREADS FOR THE PRODUCTION of

The Invention will be understood by the following:-I employ three guide bars,
a warp bar, a spool bar, or fancy bar, which are the usual bars used in a curtain
inachine. The third guide bar is arranged in the front of the other two guide bars.
In the warp bar I arrange two kinds of threads in a particular way.
The spool
bar or fancy bar is fitted with threads in the usual way. The third guide bar has
also a particular arrangement of threads. Two guide bars are acted upon in the
usual way by cams which cause the threads in the bars to move into position for

third guide bar are not acted upon by the jacks, but are moved into the position
required by the cam wheel or jacquard.
For the main warp I use two kinds of threads which I will call fine and coarse
threads; the fine threads are wound upon one beam, and the coarse threads are
wound upon another beam, to enable me to put the required weight on each kind
of threads.
I will now describe the way the threads are arranged in the warp guide bar, the
third guide bar, and the fancy bar. I arrange the threads in the warp bar as
follows: In No. 1 guide I put a coarse thread; in 2nd and 3rd, fine threads; in
the 4th, a coarse thread; in 5th and 6th, fine threads; and so on until the required
number of threads are entered in the guides of the warp bar. The guide bar for
the fancying threads I fill in the usual way with threads equal in number to the
threads in the warp guide bar. The fancying threads are wound upon separate
spools as used by the trade. The third guide bar has only one-third the number of
guides used in the warp guide bar; the guides in this bar having one or two threads
as required through each guide. The threads in this guide bar are also wound

the other threads firmly together at the crossings of the coarse threads.

the threads in the bar to rise 4 gaits; the jacks then enter the threads. The third
guide bar is acted upon at the same time as the warp bar by its cam, which causes
the threads in the bar to rise 2 gaits. The cams of the spool and warp bar again act
and cause the threads in the warp bar to rise one gait, and the threads in the spool
bar to rise three gaits, the carriages passing through the threads to the front of the
machine, and the points take up the work in the usual way. The carriages having
now gone from the back to the front of the machine, the jack bar rises one gait, the
cams again act upon the warp and spool har and allow the warp bar to fall 3 gaits
and the spool bar to fall 7 gaits. The cam again acts upon the third guide bar and
allows the threads in the bar to fall 6 gaits for the carriages to again pass through
the threads into their former position at the back of the machine. The jack bar
falls one gait, and the points take up the work as before.
The warp bar and spool bar always rise the same number of gaits when the
carriages are in the back, and fall the same number of gaits when the carriages are in
the front of the machine. The jack bar always falls one gait when the carriages are
at the back, and rises one gait when the carriages are in the front of the machine.
The third guide bar, as described, rises two gaits when the carriages are in the
back, and falls 6 gaits when the carriages are in the front, then again rises
two gaits when the carriages are in the back, and falls one gait when the

CE
The Invention will be clearly understood by the following description, in which
coarse and fine threads respectively are referred to:-I employ three guide bars, a
warp bar, a spool bar, or fancy bar, which are the usual bars used in a curtain machine.
The third guide bar is arranged in the front of the other two guide bars. In the
warp bar I arrange two kinds of threads in a particular way. The spool bar or
fancy bar is filled with threads in the usual way. The third guide bar has also a
particular arrangement of threads. Two guide bars are acted upon in the usual way
by cams which cause the threads in the bars to move into position for the
jacks to intercept the threads, and then into position for the carriages to pass
through. The third guide bar is acted upon by a cam or wheel or by a jacquard
baving the required number of motions to produce two holes. The threads in the
third guide bar are not acted upon by the jacks, but are moved into the positions
required by the cam wheel or jacquard.
For the main warp I use two kinds of threads, which I will call fine and coarse
threads, the fine threads are wound upon one beam, and the coarse threads are
wound upon another beam, to enable me to put the required weight on each kind of
thread.
I will now describe the way the threads are arranged in the warp guide bar, the
third guide bar, and the fancy bar. I arrange the threads in the warp bar as follows:-
In No. 1 guide I put a coarse thread; in the second and the third, fine threads; in the
fourth, a coarse thread; in the fifth and sixth, fine threads, and so on until the
required number of threads are entered in the guides of the warp bar. The guide.
bar for the fancying threads I fill in the usual way with threads equal in number
to the threads in the warp guide bar. The fancying threads are wound upon
separate spools as used by the trade. The third guide bar has only one third the
number of guides used in the warp guide bar, the guides in this bar having one or
two threads as required through each guide. The threads in this guide bar are also
wound upon a separate beam and can be weighted as required.
By the particular arrangement of fine and coarse threads in the warp bar I can
use the coarse threads as foundation threads, using at the same time the fine threads
to make a fancy ground. The coarse threads have to bear a greater tension to tie
the other threads firmly together at the crossings of the course threads.
By operating upon these threads with jacks I can at pleasure either tie the fine
warp threads on each side the coarse threads to the coarse threads or tie the fine
threads, which are between the coarse threads, together. The threads in the third
guide bar not being acted upon by the jacks move into positions that the wheel or
cam or jacquard may place then to cause the threads in the third guide bar to pass

page_text: over the fine thread bobbins on each side of the coarse threads, thereby causing a
straight tie across the warp threads at the top and bottom side of the hole or mesh.
The threads in the spool or fancy bar are acted upon by the jacks in a similar
way to the threads in the warp bar, which enables me to use either thread at
pleasure to fill up any portion of a hole or any of the divisions made by the
diagonal worked threads that may be inside the square hole, at the same time I am
able to fill the hole up entirely or to leave the hole (mesh) quite open. It must be
understood that by the operation of the jacks on the threads all these motions can
be made at the same time.
I now describe the way the guide bars work supposing the carriages to be in the
back. The warp guide bar is acted upon by its cam, which causes the threads in the
bar to rise two gaits. The spool or fancy bar is acted upon by its cam, and causes
the threads in the bar to rise four gaits, the jacks then enter the threads. The third
guide bar is acted upon at the same time as the warp bar by its cam, which causes
the threads in the bar to rise two gaits. The cams of the spool and warp bars again
act and cause the threads in the warp bar to rise one gait, and the threads in the
spool bar to rise three gaits, the carriages passing through the threads to the front of
the machine, and the points take up the work in the usual way. The carriages
having now gone from the back to the front of the machine, the jack bar rises one
gait, the cams again act upon the warp and spool bars, and allow the warp bar to
fall three gaits and the spool bar to fall seven gaits. The cam again acts upon the
third guide bar, and allows the threads in the bar to fall six gaits for the carriages
to again pass the threads into their former position at the back of the machine. The
jack bar falls one gait, and the points take up the work as before.
The warp bar and spool bar always rise the same number of gaits when the
carriages are in the back, and fall the same number of gaits when the carriages are
in the front of the machine. The jack bar always falls one gait when the
carriages are at the back, and rises one gait when the carriages are in the
front of the machine. The third guide bar as described rises two gaits when
the carriages are in the back, and falls six gaits when the carriages are in the
front, then again rises two gaits when the carriages are in the back, and falls one
gait when the carriages are in the front; this bar then rises one gait and falls one
gait at each movement of the carriages until the seventeenth motion. The carriages
being then in the back the bar falls one gait, the carriages pass to the front, the bar
then rises six gaits, the carriages pass to the back, the bar then falls two gaits, the
carriages again pass to the front, the bar then rises one gait, and at the next motion
falls one gait. The bar then rises one gait and falls one gait at each movement of
the carriage until the twenty-second motion, the carriages being then in the front
of the machine. The bar rests during this motion, and the carriages again pass to
the back, the bar then rises one gait and falls one gait as before at each movement 4
of the carriages until the thirty-second motion; the wheel is then in the position as
first described, having caused the threads in the third guide bar to pass over the
bobbins each side of the thick threads, and then twist down the pillars to form
a straight tie across the warp threads.
One of the coarse threads in the warp bar may be carried by an additional guide 4
bar, the other threads being carried as above described.
I have referred to the fancy bar as rising four gaits at one time, but the same
effect can be obtained by rising the bar or threads one gait first and then three
gaits, after which it would fall four gaits.
In the accompanying Drawings A shews the carriage in the back of the machine; 5
B is the carriage in the front of the machine; C is the third guide bar; D is the
spool or fancy bar; E is the warp guide bar; F is the stump bar with the
stump led screwed to it; G is the jacks which act upon the thread's; H is the jack
bar with the jacks screwed to the bar; K is the warp beam having the thick
threads; L is the warp beam having the fine threads; M is the beam having the 5
threads which pass through the guides in the third guide bar; N shows the
spool thread which passes through the fancy bar D; O is the lever which pulls off

page_text: the cotton from the spools or bobbin's; P shows the wheel which operates on the
third guide bar C; R shews portions of holes filled up with the spool or fancy
thread; S shews holes filled up completely, and holes T left entirely open; Ushews
the work passing up the work bar; V, the combs which guide the carriages; W,
the comb bar with the comb leads screwed to the bar; X and Y shew iron rods to
guide the fine and coarse warp threads; Z shews a sley through which all threads
pass.
In the foregoing I have described a series of fine and of crarse threads being used
in a special manner for a special result, but I do not confine myself to the use of fine
and coarse threads in combination only, as the warp threads may be all of the same
thickness, the arrangement of the threads being the same.
Having now described the nature of my said Invention, and the manner the
same may be performed, I declare that claim,-
Firstly. Manufacturing "guipure" lace or imitation "guipure" lace on a twist
lace machine, by and the special arrangement of mechanism as set forth.
Secondly. The special arrangement of threads as described by which "guipure'
lace or imitation "guipure "lace can be produced in or by a twist lace machine.
