page_text: We, JOSÉ REIXACH, a Managing Director of Lister & Co., Ld., of Manninghain
Mills, Bradford, in the County of York, and HERBERT SCOTT, of the same address,
Manufacturers Assistant, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to obtain a jacquard machine for the production of
figured pile fabrics woven face to face, or other fabrics, in which two separate sheds
are formed at the same time and two shuttles are thrown simultaneously one into
each shed.
This invention is specially useful for the production of figured double pile fabrics
woven face to face in which the jacquard is required to cause the different pile
threads to lie in three different positions at the same time, that is, either at the
bottom of the shed, both shuttles passing over, or between the two sheds, the bottom
shuttle passing under and the top shuttle passing over, or at the top of the shed,
both shuttles passing under.
The jacquard is driven from the top shaft of the loom by two cranks connected by
rods to two knife boxes. The cranks are set to act together one giving twice as
much travel as the other so that ore knife box rises to the full lift and the other to
the half lift. Each thread is worked by two needles, one needle is raised by the half
lift knife box and is selected by a card cylinder situated on one side of the machine
and the other needle is raised by the full lift knife box and is selected by a card
cylinder, preferably on the other side of the machine.
The cards on each cylinder are cut according as it is desired to allow the threads
to remain at rest at the bottom, or to raise them to the half or middle lift, or to the
top or full lift.
In a modification two separate jacquards are used, one (the full lift) giving twice
as much travel as the other (the half lift). Each thread is connected to a needle in
the full lift jacquard and also to a needle in the half lift jacquard. When the cards
of both jacquards are so cut as to allow the needles of both jacquards to be down the
thread remains at the bottom; when the needle of the half lift jacquard is raised the
thread is raised to the middle between the two sheds. When the needle of the full
lift jacquard is raised the thread is raised to the top of the two sheds. Either the
well-known "single lift" or the "double lift" type of jacquard may be used.
In another modification instead of each thread being worked by two separate
needles as in the two previous cases one needle only is used to obtain the three
different positions of the thread. In this machine a rising knife box and a falling
wire, or wooden tray act simultaneously, the needle is bent upward to form a
secondary hook on the reverse side to the usual or primary hook and the bend which

page_text: is thus formed at the bottom of the needle rests on the wooden tray. One set of
cards cylinder and wires is used to actuate the primary hook and cause it to engage
when desired with the rising knife box and so obtain the top lift; a second set of
cards cylinder and wires causes the secondary hook to catch on a fixed knife, or not,
as desired; when so caught the néédle remains at the middle lift; when not so
caught the needle falls with the falling wooden tray to the bottom position.

We, JOSE REIXACH, a Managing Director of Lister & Co., Ld., of Manningham
Mils, Bradford, in the County of York, and HERBERT SCOTT, of the same address,
Manufacturers' Assistant, do hereby declare the nature of this invention and in what
mauner the same is to be perforдned to be particularly described and ascertained in
and by the following statement :-
The object of this invention is to obtain a jacquard machine for the production. of
figured pile fabrics woven face to face, or other fabrics, in which two separate sheds
are formed at the same time and two shuttles are thrown simultaneously one into each
shed.
This invention is specially useful for the production of figured double pile fabrics
woven face to face in which the jacquard is required to cause the different pile threads
to lie in three different positions at the same time, that is, either at the bottom of
the shed, both shuttles passing oyer, or between the two sheds, the bottom shuttle
passing under and the top shuttle passing over, or at the top of the shed, both
shuttles passing under.
The jacquard is, driven from the top shaft of the loom by two cranks connected
by rods to two kuife boxes. The cranks are set to act together one giving twice as
inuch travel as the other so that one knife box rises to the full lift and the other to
the half lift. Each thread is worked by two needles, one needle is raised by the half
lift knife box and is selected by a card cylinder situated on one side of the machine,
and the other needle is raised by the full lift knife box and is selected by a card
cylinder, preferably on the other side of the machine.
The cards on each cylinder are cut according as it is desired to allow the threads to
remain at rest at the bottom, or to raise them to the half or middle lift, or to the top
or full lift.
Figures 1 and 2 shew jacquard mechanism arranged as above. described. The
jacquard is driven by the two connecting rods A B which are worked in the usual
way by cranks on the top shaft of the loom or by tappets.
Levers A B pivotted at C transfer the motion through the rods A2 B to the knife
boxes A3 B3 carrying the knives A' B'. DD1 D2 D3 D' D' are the upright needles,
EG are the card cylinders actuating the needles H K, and causing the upright
needles D D¹ etc. to be lifted by the knife boxes A B or to remain at the bottom, as
desired.
The knife box B³ is caused to travel from the position shewn in Figure 1 which is
the bottom of the stroke given by the crank or tappet by means of the rods B B
and lever B¹ to the position shewn in Figure 2, which is the top of the stroke, at the
same time as the knife box As is caused to travel to the position in which it is shewn
in Figure 2 by means of the rods A.A2 and lever A. It will be seen that the travel

page_text: given to B is sufficient only to raise the threads from the bottom to the middle
position as shewn at O Figure 2, and is half that given to A which raises the threads
to the top position as shewn at M.
Figure 1 shews the jacquard at the bottom of the stroke at which point both card
cylinders E and G press up and select the needles which are to be carried up by the
knives A and B. The upright needles D D' are connected by bands to the same
mail L. D2 D3 are connected to the mail M. D D are connected to the mail O.
The upright needle D is allowed to be held off the knife B by the card cylinder E
the horizontal needle with which it is connected entering a hole in the card and D is
pressed off the knife A by the card cylinder G, there being no hole for its horizontal
needle to enter, consequently when the knives rise and the jacquard is at the top of
the stroke these needles remain and give the bottom position L. (see Figure 2.) The
upright needle D3 on the other hand is selected by the card cylinder G to be caught
by the knife A and raised to the full lift giving the top position M, Figure 2. The
upright D is selected by the card cylinder E to be caught by the knife B the
upright D' being pressed off' the knife A+ by the card cylinder G, this gives the middle
position O Figure 2.
In a modification shewn at Figure 3 two separate jacquards are used, one (the full
lift) giving twice as much travel as the other (the half lift). Each thread is
connected to a needle in the full lift jacquard and also to a needle in the half lift
jacquard. When the cards of both jacquards are so cut as to allow the needles of both
jacquards to be down the thread remains at the bottom; when the needle of the
half lift jacquard is raised the thread is raised to the middle between the two sheds.
When the needle of the full lift jacquard is raised the thread is raised to the top of
of the two sheds. Either the well known "single lift" or the "double
lift" type of jacquard may be used.
The half traeel to raise the mails to the position shewn at O is given through the
rods PP and lever Pl pivotted at Q actuating the knife box 13 and knives P and also
by the rods R R and lever R actuating the knife hox R3 and knives R.
The full travel to raise the mails to the position shown at M is given through the
rods S S and lever Si pivotted at Q actuating the knife box S3 and knives Sand
also by the rods T T and lever T actuating the knife box Ts and knives T*.
The upright needle V in the short travel jacquard and the needle V1 in the full
travel jacquard are connected by bands to the same mail L, the needles W and Wi
are connected to the mail O and the needles Y and Y to the mail M. The card
cylinders E G actuating the needles H and K select the upright needles which are
to be lifted to the half lift or to the full lift as already explained.
In another modification instead of each thread being worked by two separate
needles as in the two previous cases one needle only is used to obtain the three
different positions of the thread. In this machine a rising knife box and a
falling wire, or wooden tray, act simultaneously, the needle is bent upward to
form a secondary hook on the reverse side to the usual or primary hook and the
bend which is thus formed at the bottom of the needle rests on the wooden tray.
One set of cards cylinder and wires is used to actuate the primary hook and
cause it to engage when desired with the rising knife box and so obtain the top
lift; a second set of cards cylinder and wires causes the secondary hook to catch
on a fixed knife, or not, as desired; when so caught the needle remains at the
middle lift; when not so caught the needle falls with the falling wooden tray to the
bottom position.
Figures 4, 5, 6, 7 and 8 represent the above modification.
Figure 4 is a view of the complete machine. 10 is a rising knife box lifted by the
rod 11 and carrying the knives 12. 13 is a wire or wooden tray or board inoved
vertically up and down by the rod 14. G is the card cylinder controlling the upright
needles 15 by means of the needles K and pressing the primary hooks 16 off the
knives 12 or allowing them to remain on as desired. E is the secondary card cylinder
controlling the lower part of the upright needles 15 and pressing the secondary
hooks 17 off the fixed knives 18 or allowing them to remain on as desired. The card

page_text: cylinder G is suspended by the arm 19 and pivoted at 20. The card cylinder E is
suspended by the arm 21 and pivotted at 22 in the usual way. Spring boxes 23
and 24 return the needles H and K and the upright needles 15 to their places after
the pressure of the cylinders.
The method of working the Jacquard is as follows:-
Figure 5 shows the position of the Jacquard at which both the card cylinders G
and E press up and select the needles. Figures 6, 7 and 8 represent the three
different positions of the needles when the Jacquard is at the full stroke or lift. To
obtain the middle position shown in Figure 6 the card cylinder G is caused to press
the hook 16 off the knife 12 and the card cylinder E allows the hook 17 to remain on
the fixed knife 18 and thus prevent the needle from falling with the travelling
board 13; the thread 25 is thus left in the middle between the two sheds the top
shuttle 26 passing over it and the bottom shuttle 27 passing under it.
To obtain the top position shown in Figure 7 the card cylinder G allows
the hook 16 to remain on the travelling knife 12 which on rising carries the
needle 15 with it and takes the thread 25 to the top above both sheds both
shuttles 26 and 27 passing under it.
To obtain the bottom position shown in Figure 8 the card cylinder G presses the
hook 16 off the travelling knife 12 and the card cylinder E presses the hook 17 off
the fixed knife 18. The needle 15 is thus left free to fall with the board 13 and take
the thread 25 to the bottom below both sheds, both shuttles 26 and 27 passing over
it.
At each pick of the loom, at the time when the shuttles are about to cross the
travelling knife 12 rises and the falling board 13 falls from the position shown in
Fig. 5, to that shown in Figures 6, 7 and 8, so that any one of these three positions
can be given to each pile thread at every pick of the loom and the pile threads can be
tied in to the top or bottom pieces or brought to the middle between the two pieces,
28 and 29 are the warp threads for the top piece and 30, 31 are the warp threads for
the bottom piece, these may be tied in in any well known manner.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is
1. Jacquard mechanism to be used in the production of pile fabrics woven face to
face when two sheds are to be formed at the same time for two shuttles to be thrown
simultaneously in which two upright needles are coupled to each warp thread which is
to be acted on and in which there are two knife boxes one having double the lift of the
other the knives in one box acting with one set of needles and the other with the
other set and a card cylinder and horizontal needles for selecting from each set of
needles the needles that are to be raised by the knives of the two knife boxes.
2. The combination of two complete Jacquard mechanisms to be used in the
production of pile fabrics woven face to face when two sheds are to be formed at the
same time for two shuttles to be thrown simultaneously one having double the lift of
the other and connections from each warp thread to one of the lifting needles in each
mechanism.
3. Jacquard mechanism to be used in the production of pile fabrics woven face to
face when two sheds are to be formed at the same time for two shuttles to be thrown
simultaneously in which each warp thread to be acted on is connected to two hooks
one to engage with a fixed knife the other to engage with a knife in a rising and
falling knife box and in which there is a tray for the hooks to rest on which descends
as the knife box rises and rises as the knife box descends and one or more jacquard a
barrels and horizontal needles for selecting which hooks shall be carried up by the
rising knife box or lowered with the train or reinain hooked on to the fixed knives.
4. Jacquard mechanism to be used in the production of pile fabrics woven face to
face when two sheds are to be formed at the same time for two shuttles to be thrown
simultaneously in which each warp thread to be acted on is connected to a bent
needle formed with two hooks one to engage with a fixed knife the other to engage

page_text: with a knife in a rising and falling knife box and in which there is a tray on which
the needles can rest and which descends as the knife box rises and rises as the knife
box descends and one or more jacquard barrels and horizontal needles for selecting
which vertical needles shall be carried up by the rising knife box or lowered with the
tray or allowed to remain hooked on to the fixed knives.
