Improvements in the Mode of and in Apparatus for Connecting
Together the Pattern Cards used in Jacquard Weaving.
We, THOMAS BLACKHURST, of 14 London Terrace, Darwen, in the County of
Lancaster, Overlooker, and THOMAS ROBERTS, of 51 Richmond Terrace, in the
same town, Cotton Mill Manager, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in the mode of and in apparatus for
connecting together the pattern cards used in Jacquard weaving.
The usual mode employed for connecting such cards together is by a process
of sewing or stitching. The twine or string employed for this purpose is passed
through holes or perforations punched or otherwise formed through the card.
According to our invention we dispense with the said holes or perforations-
thereby leaving the cards stronger and hold each card in place within a loop
formed by the intertwining of an upper and lower strand of string twine tape or
other suitable material. At the adjoining edges of the cards where the twisting of
the two strands occurs we cut out semi-circular notches the two opposite notches
forming a circular space which allows the twisted portion of the string or twine to
lay flat or flush with the cards and also permits the adjoining edges of the cards to
be brought up close to each other in the ordinary way. The notches moreover
enable the cards to be firmly held in place within the loops enclosing the said
cards.
The apparatus we employ in carrying out our invention consists of an ordinary
four-sided Jacquard cylinder which is automatically pulled over a quarter of a turn
at a time by a book of the usual kind the card last operated upon (that is to
say intertwined or enclosed between the two strands) lying flat on the upper side
of the cylinder. The two strands are actuated after the fashion of the warp
threads in a loom and each time the "shed" opens the next card is introduced by
hand endwise between the two strands and brought close up to the cylinder in line
with the preceding card and held in position until the strands have been again
crossed when another card is inserted as before the cylinder having meanwhile been
pulled over to the extent of a quarter of a turn. The twisting of the two
strands at the edge of the card may be effected in the following manner :-A
geared wheel having a crank pin gives an up and down reciprocatory movement
to a vertically arranged connecting rod which actuates a quadrant above in gear
with another wheel (hereinafter termed the "shedding wheel") also carrying a
crank pin from which depends a frame carrying two or more light rods (hereinafter
termed the "shedding rods") whose lower extremities are perforated or needle-
eyed and through the needle eyes one set of the strands pass. The crank pin on
the shedding wheel is preferably placed or arranged over or above the axis of the
said wheel and as the latter is partially rotated by the action of the quadrant first
in one direction and then in the other the shedding rods are not only lifted up and
down but have also a sidewise movement imparted to them so that their needle-
eyed ends are caused to pass first on one side and then over to the other of other
fixed vertical rods having their upper extremities also needle-eyed and through
which pass the other set of strands. The lower end of the frame carrying the
shedding rods is controlled in suitable guides and by means of springs and a device
preferably operated by foot power is provided whereby the apparatus may be
stopped and started at will.

page_text: In some cases we prefer to put several twists or turns into the two strands as for
instance when it is desired to increase the distance apart between each adjoining
pair of cards. This may be effected by passing one strand through a central or
axial hole of a revolving flanged spool and bringing the second strand (wound upon
the spool) through an aperture or loop arranged on the outside edge of one of the
spool flanges. Under such circumstances the apparatus would be driven at a
quicker speed during the twisting operation and stopped during the introduction of
each succeeding card within the shed in the manner first herein before mentioned.

Improvements in the Mode of and in Apparatus for Connecting
Together the Pattern Cards used in Jacquard Weaving.
We, THOMAS BLACKHURST, of 14 London Terrace, Darwen, in the County of
Lancaster, Overlooker, and THOMAS ROBERTS, of 51 Richmond Terrace, in the
same town, Cotton Mill Manager, 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 mode of and in apparatus for
connecting together the pattern cards used in Jacquard weaving.
The usual mode employed for connecting such cards together is by a process of
sewing or stitching. The twine or string employed for this purpose is passed
through holes or perforations punched or otherwise formed through the card.
According to our invention we dispense with the said holes or perforations-
thereby leaving the cards stronger-and hold each card in place within a loop
formed by the intertwining of an upper and a lower strand of string twine tape or
other suitable material. At the adjoining edges of the cards where the twisting of
the two strands occurs we cut out semi-circular notches the two opposite notches
forming a circular space which allows the twisted portion of the string or twine to
lay flat or flush with the cards and also permits of the adjoining edges of the cards
to be brought up to each other in the ordinary way. The notches moreover
enable the cards to be firmly held in place within the loops enclosing the
said cards.
The apparatus we employ in carrying out our invention consists of an ordinary
four-sided Jacquard cylinder which is automatically pulled over a quarter of a turn
at a time by a hook of the usual kind the card last operated upon (that is to say
intertwined or enclosed between the two strands) lying flat on the upper side of the
cylinder. The two strands are actuated somewhat after the fashion of the warp
threads in a loom and each time the "shed" opens the next card is introduced by
hand end wise between the two strands and brought close up to the cylinder in line
with the preceding card and held in position until the strands have been again
crossed when another card is inserted as before the cylinder having meanwhile been
pulled over to the extent of a quarter of a turn. The twisting of the two strands at
the edge of the card may be effected in the following manner :-A geared wheel

irst in one direction and then in the other the shedding rods are not only lifted up
nd down but have also a sidewise movement imparted to them so that their
eedle-eyed ends are caused to pass first on one side and then over to the other of
ther fixed vertical rods having their upper extremities also needle-eyed and
hrough which pass the other set of strands. The lower end of the frame carrying
he shedding rods is controlled in suitable guides and by means of springs and
device preferably operated by foot power is provided whereby the apparatus may
be stopped and started at will.

11 represents the outer framework of the said apparatus 2 a cross shaft having
on one end a fast or driving pulley 3 and a loose pulley 4 and on its other end a
pinion 5 geared into the toothed wheel 6. The wheel 6 carries a side cam 7 and a
tappet cam 8. 9 is a cross shaft capable of being rotated and also of being moved
endwise in its bearings 10 10 the said shaft carrying the oscillating fingers 11 11
which operate as the "shedding rods hereinbefore referred to having their
extremities 12 needle-eyed through which one set 13 of the strands pass. The
rotation of the tappet cam 8 moves up and down an arm 14 fast upon one end of
the shaft 9 and the side cam 7 moves through the medium of the pivoted arm 15
the shaft to and fro sidewise producing the movements of the shedding rods 11 11
illustrated by dotted lines at Figs. 6 and 7. The arm 14 is held down upon its
tappet cam 8 by a spring (such as 19) and the pivoted arm 15 is held against its
side cam 7 by means of a bent flat spring (not shewn in the drawings for the sake
of greater clearness). 20 and 20* are anti-friction bowls or rollers carried on the
sides of the arms 14 and 15 respectively. As will be seen by reference to Figs. 6
and 7 the needle-eyed fingers 11 11 lift the strands 13 first to one side and then over
to the other of fixed vertical rods 16 16 having on their upper extremities—
instead of being needle-eyed as first. bercinbefore mentioned-small grooved anti-
friction pulleys 17 17 over which the other set 18 of the strands is carried. 21 is a
fixed bar from which depend hangers or hooked fingers 22 22 which support the
spools or bobbins 23 23 upon which the two sets of strands in each case are carried.
24 24 are spring tension plates between which the strands pass after leaving
the spools the set of strands 13 being then passed behind the bar 21 and over the
shaft 9 through the needle-eye on the shedding rod 11 (see Fig. 6) and to the
Jacquard cylinder 25 whilst the strand 18 is passed through a hole in a cross bar 26
over the pulley 17 and so on to the Jacquard cylinder. The partial rotary
movement of the shaft 9 raises and lowers the extremity of another arm 27 which
thereby through the medium of a suitable connecting rod and rocking lever
operates a hook 28 which in turn rotates to the required extent the Jacquard
cylinder 25. The cylinder shewn in the drawings is eight-sided being more
convenient for cards of the larger sizes than a four-sided cylinder which we use
with the smaller sizes of cards. 29 is a pivotted break block arranged to rest
partly upon the face of the driving pulley 3 the said block being brought down on
the pulley by the foot lever 30 so that the apparatus may be temporarily stopped
when required the driving belt meanwhile slipping over the face of the pulley 3 as
will be well understood. 31 is a shelf upon which the loose cards to be connected
together may conveniently be placed and 32 is a guide roller over which the
chain 33 of connected cards is preferably passed.
Figs. 8 and 9 and Figs. 10 and 11 (the latter being drawn to a larger scale)

page_text: illustrate the under and over method of intertwining strands so as to connect
pattern cards together according to our said invention 34 34 being the cards and
35 35 the semicircular notches in the edges of the cards herein before referred to.
In Fig. 9 the cards are shewn connected near each end only but for longer cards a
centrally arranged strand may be required.
In some cases we prefer to put several twists or turns into the two strands as for
instance when it is desired to increase the distance apart between each adjoining
pair of cards. This may be effected by passing one strand through a central or
axial hole of a revolving Hanged spool and bringing the second strand (wound upon
the spool) through an aperture or loop arranged on the outside edge of one of the
spool flanges. Under such circumstances the apparatus would be driven at a
quicker speed during the twisting operation and stopped during the introduction of
each succeeding card within the shed in the manner first hereinbefore mentioned.
Fig. 12 illustrates the mode of connecting the cards when several twists or turns
are put into the strands between each adjoining pair of cards and
Figs. 13 and 14 apparatus for effecting the required extra twisting or turning of
the strands.
23 23 are the spools containing the strands 13 which respectively pass through
the axial or central hole of the spools 36. The strand 18 on the spools 36 is
preferably passed through a perforated or needle-eyed arm or finger such as 37.
The toothed wheel 6 carries a crank pin 38 a connecting rod 39 and a pivoted
lever 40 serving to lift and depress the hook 41 which successively engages with
the pins 42 42 and so rotates the large toothed wheel 43. The wheel 43 gears into
a pinion 44 on the boss or hub of a toothed wheel 45 which in turn imparts rotation
to the toothed wheels 46 and 47 upon a barrel projecting from each of which is held
so as to rotate therewith a spool such as 36 (see Fig. 14).
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The mode of connecting together pattern cards used in Jacquard weaving
substantially as hereinbefore described and shewn in the drawings.
2. The combination of parts constituting the apparatus described with reference
to Figs. 1, 2, 3, 4 and 5 of the drawings arranged constructed and operating
substantially as described and shewn in the drawings for the purpose specified.
3. The combination of parts constituting the apparatus described with reference
to Figs. 13 and 14 of the drawings arranged constructed and operating substantially
as described and shewn in the drawings for the purpose specified.
