Improvements in Jacquard Card Lacing Machines.
I JAMES NUTTALL of Ben Mill, Heap Bridge near Bury in the County of
Lancaster, Machine Maker do hereby declare the nature of this invention to be as
follows:-
My invention relates to Jacquard card lacing machines and consists in an im-
proved machine for lacing Jacquard cards by sewing them together with two
threads forming a lock stitch.
I arrange the frame of the machine, link chains with pegs for feeding the cards
forward, grooved slides for the chain links to travel in adjustable laterally on the
table of the machine, needle bar and cam shaft for operating the same in a similar
manner as in the Jacquard card lacing machine for which Letters Patent No. 11639
dated the 13th August 1888 were granted to me. Each of the said grooved slides
is formed with a longitudinal box or channel in which a shuttle driver or carrier
slides. The several shuttle carriers are formed with lugs projecting below the boxes
passing through slots in the bottom of the same, and a bar is passed through these
several lugs and secured by set screws or pins. This bar receives a reciprocating
motion from excentrics or cams mounted on the cam shaft through levers and links
and thus a simultaneous reciprocating motion is imparted to the several shuttle
carriers and to shuttles held in the same containing the under thread on spools or
cops, the arrangement of shuttles and carriers being similar to that used in ordinary
shuttle sewing machines.
The needles are fixed in holders adjustable laterally on a needle bar and the
threads taken to them from bobbins on a creel through thread guides and takers up,
ware preferably arranged as follows:-Behind each needle holder a bracket
is fixed underneath the creel plate with a stud on which the taker-up oscillates. To
the needle holder a link is joined and connected to the taker-up which is formed
with a series of holes for the connecting pin, so as to adjust the leverage and move-
ment of the taker up. The thread passes through the creel plate to a thread
guide behind the taker up, thence through an eye in the end of the same, which is
above the needle holder, and through a perforation of the latter to the needle. The
taker-up thus moves simultaneously with the needle but makes a longer movement.
The cams actuating the needle bar are so formed that after drawing the needles
down and lifting them a short distance so as to form loops the needles dwell in this
position till the shuttle noses have entered the loops, after which the needles Fre
slightly lowered again so as to pay out thread while the shuttles widen the loops cut
and pass, after which the needles are lifted again, and the taker-up draws the
thread tight.
The cards are placed upon the pegged link chains and advanced by them after
each stitch. The chain pulley shaft may be rotated intermittently by means of a
single cog
and star wheel as described in Specification No. 11639 of 1888, the str
wheel being made in some cases with two teeth shorter than the others when the
cards to be sewn have laceholes already punched in them, so that a descent of the
needle takes place into the said laceholes and another between the two cards. By
preference however I use an arrangement of peg wheel and ratchet similar to that
described in the Specification of the card repeating machine for which Letters.
Patent No. 1822 dated the 4th of May 1880 have been granted to me. A ratchet
wheel fixed on the chain pulley shaft is acted upon by two pawls attached to two
bell crank levers which are lifted alternately by the bowls fixed on opposite sides
of a spur wheel making one revolution for two of the cam shaft. The motion of a

page_text: bellcrank lever draws the respective pawl back and the lever is pulled down by a
spring and advances the pawl and ratchet, as soon as a stop lever liberates a peg
wheel keyed upon the chain pulley shaft. The peg wheel has a number of laterally
projecting pegs, between which tongues on the stop lever can enter and the wheel is
stopped by the tongues. One of the tongues is fixed to the end of the stop lever
and another below the former to a bolt sliding in the lever and pushed outwards by
a spring. When a peg rests against the upper tongue, the lower one is pushed out
underneath the pegs.
The lever is suddenly lifted and the fixed tongue taken off
the peg by a cam or equivalent means when the feed is to take place, and the
sliding tongue is thereby brought before the next following peg. The springs
acting on one of the pawls then pushes the shaft round and the peg pushes the
sliding tongue against a stop on the stop lever so that it is underneath the fixed
tongue. The stop lever then drops and the fixed tongue is brought before the peg
and holds it while the stitch is formed. This arrangement allows any required
length of feed or stitch to be given by spacing the pegs at corresponding distances,
so that the needles can be made to descend between the cards and into previously
punched lace holes at any distance from each other.
The needles may however also form their own holes in cards having the peg
holes only punched into them.

improvements in Jacquard Card Lacing Machines.
1, WILLIAM NUTTALL of Ben Mill, Heap Bridge, executor of the late James
Nuttall of Ben Mill, Heap Bridge in the County of Lancaster, Machine Maker, 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 :-
My invention relates to Jacquard card lacing machines and consists in an improved
machine for lacing Jacquard cards by sewing them together with two threads forming
a lockstitch.
On the sheet of drawings appended hereunto
Figure 1 shows a longitudinal section through the upper part of the machine.
Figure 2 a front view of the thread guides and taker-up.
Figure 3 a cross-section through one of the shuttle boxes.
Figure 4 a plan of the same.
Figure 5 a partial view of cards laced together.
I arrange a frame a of the machine, link chains 6 with pegs for feeding the cards
forward, grooved slides for the chain links to travel in, adjustable on the open
table top a¹ of the machine, needle bar and cam shaft e for operating the same in
a similar manner as in the Jacquard lacing machine for which Letters Patent
No. 11639 dated the 13th August 1888 were granted to James Nuttall and described
in the Specification for said Patent, and have only shown or indicated these
parts on the drawings appended hereunto as far as necessary for elucidating my
improvements.
Each of the grooved slides c, of which there may be two, three or more according
to the width and kind of jacquard cards to be laced, is formed with a longitudinal
box or channel c¹ in which a shuttle driver or carrier f slides. The several shuttle
carriers are formed with lugs f projecting below the boxes c¹ and passing through
slots in the bottom of the same, and a bar or rod g is passed through these several
lugs and secured to the lugs of the outer carriers by set-screws or pins or held in
position by equivalent means. This bar receives a reciprocating motion from an
1

page_text: excentric g fixed upon the cam shaft e, strap g', rod g³, lever g* and connecting rod g
and thus a simultaneous reciprocating motion is imparted to the several shuttle
carriers and to shuttles held in the same and containing the under thread on
spools or cops, the arrangement of the shuttles and carriers being similar to that
used in ordinary shuttle sewing machines. Instead of the excentric a cam actuating
the lever and spring for holding the same against the cam or their equivalents
may be used.
The needles n are fixed in holders d'adjustable laterally on the needlebar d and
the upper threads taken to them from bobbins arranged on a creel through thread
guides and takers up, which are preferably arranged as follows: Behind each
needle holder d¹ brackets h¹ are fixed underneath the creelboard h³ with pegs or
their equivalent on which the bobbins are placed. Other brackets are fixed
behind each needle carrier to the creelboard and have studs l screwed to them
on which the bent takers-up m oscillate. Each needle holder has formed on or
attached to it a lug d or its equivalent to which a link m³ is joined and connected
to the taker-up m by a pin, the taker-up being formed with a series of holes for
the connecting pin for the purpose of adjusting the leverage and the movement of
the taker-up. The threads pass from the bobbins in the manner indicated by a
dotted line through thread guides i, round tension pulleys of usual construction
and through holes in the creelboard to the eyelets m* at the lower end of the
takers up m, thence through eyelets m' at the upper ends and through holes in the
needle holders d to the needle eyes. The taker-up moves simultaneously with
the needle; during the down stroke of the needle, m¹ moves forwards and down-
wards, while m² moves upwards, both paying out thread to the needle, while during
the up stroke they make the reverse movements and take up loops formed by the
shuttle and tighten the thread upon the cards.
The needle bar d is attached at the ends to vertical slide rods d³ carrying
bowls d' at the bottom and arranged similarly as in the machine described in the
Specification hereinbefore referred to. The cams o actuating the needle bar are
formed with grooves into which the bowls enter and of the form shewn on the
drawing. The bar is drawn down while the bowls roll along the part o¹ of the
groove till they arrive at o³, when the bar and needles are lifted for the formation
of the loop for the shuttle tip to enter into while the bowls roll to o³. While the
bowls roll on to of the bar and needles are drawn down again for the purpose
of paying out thread while the shuttles widen the loops out and pass through them,
after which the needles are lifted again while the bowls roll along o' and the taker
up draws the thread tight.
The cards are placed upon the pegged link chains b, and held down by pressers s
fixed upon a bar s¹, and advanced after each stitch. The needles may make their
own holes through the cards, or lace holes may be punched into the cards pre-
viously. In the latter case there will be two short stitches pp where two
consecutive cards come together, and three or more longer stitches on the cards
themselves as shewn by the sketch Fig. 5. This can be effected by means of a
single cog wheel and star wheel arranged similarly as described in the
Specification herein before referred to, the star wheel being made with two shorter
teeth and three or more longer teeth, so that a descent of the needles takes
place into each of the lace holes and one between the cards. The motion of the
star wheel is transmitted to the chain wheels by spur gearing. Instead of this
an arragement of peg wheel and ratchet similar to that described in the Specification
of the card repeating machine for which Letters Patent No. 1822 dated the
4th of May 1880 have been granted to James Nuttall, may be used, the pegs
being spaced so as to give the required length of feed or stitch, so that the needles
can be made to descend into previously punched lace holes at any distance from
each other.
The lacing machine hereinbefore described may be combined with a iace and peg
hole punching machine arranged on the same fraine.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
Firstly. The general arrangement and combination of parts of a Jacquard card
lacing machine substantially as hereinbefore described.
Secondly. In a Jacquard card lacing machine the arrangement of shuttle carriers
strung upon a rod actuated by a single excentric or its equivalent, substantially as
hereinbefore described and illustrated.
Thirdly. In a Jacquard card lacing machine the arrangement of taker up sub-
stantially as herein before described and illustrated.
Fourthly. In a Jacquard card lacing machine the arrangement or formation of
the cams actuating the needles in such a manner that the needles descend
again after the shuttle tip has entered the loop, substantially as hereinbefore
described and illustrated.
Fifthly. In a Jacquard card lacing machine the construction or arrangement of
star wheels with teeth of varying pitch substantially as hereinbefore described and
illustrated and for the purpose set forth.
Dated this 8th day of May 1891.
