A Machine for Tying or Lacing together the Cards used in Jacquard
Machines.
1, GEORG PAULICK of Leipzig, in the Empiro of Germany, Manufacturer, do
hereby declare the nature of this invention to be as follows :-
The object of this invention is a machine for tying up Jacquard cards, in
which the cards are introduced by hand into the machine and are so moved by
means of a special transport mechanism that the advancing corresponds to the
non-uniform distances of the stitch- or tying-up-places. The needles are moved
by particular contrivances, the needle thread being held fast in a peculiar manner
at the moment the shuttle loop is formed. The tension i.e. the drawing off of the
needle thread from the bobbins is effected through a separately acting mechanism,
which is also the case with the movement of the shuttles.
The latter operate
below the table surface and straight needles are employed.
The improved machine is in the main disposed as follows:
In a stand or frame provided with table is lodged a shaft actuated by a strap
pulley or the like. Said shaft carries at one end a pinion and at each end a
clutch coupling device, one serving to stop the machine and the other to allow
the spooling disc to be operated when the machine is at rest. The pinion gears
into a wheel mounted on a shaft provided parallel to, and at about the same height
with, the shaft referred to. This second shaft has at each end a cam wheel for
driving the needle sticks. On the same shaft are mounted a transport cam by the
side of a cam for taking off the thread, and a driving wheel. The latter actuates
a wheel mounted on a vertical crank shaft which serves to operate the shuttle
holder or basket, moved to and fro in the race by a draw rod. The cam wheels
mentioned above move the needle stick carriers up and down so that the needles
penetrate at the proper time, prior to the passage of the shuttle, into the shuttle
race.
At the same time the needle clamping mechanism is actuated which consists of
springs secured to the needle bar and provided with slanted surfaces and of a
stationary rail. The needle bar descends and the thread is stretched when the
needle occupies its lowest position by the thread being held fast by said spring
through co-operation of the slanted surface and rail. The clamping fast of the
thread is for some time continued when the needle reascends, so that the thread of
the needle can evade only in the direction to the shuttle loop, whereby the loop
for the passage of the shuttle is infallibly formed.
In order to conform the distance of the stitches to the division or width of the
cards, the following transport mechanism is provided.
Two parallel shafts lodged underneath the table carry cach two chain pulleys
over which run chains provided with a take-about. One of these shafts carries
a double stop disc. One of these two discs has five and the other fifteen stop
teeth, which numbers may however also be varied into seven and twenty one etc. in
accordance with the division. Said discs co-operate as follows:
Into the teeth of the disc with fifteen teeth catches a click-arm secured to a
two-armed lever, while the other disc influences a bolt attached to said lever.
According to the position of this bolt in one of the interstices between the disc
with five teeth, the said click lever is more or less raised, thereby determining the
intermittent turning of the respective chain pulleys and their shafts.
When the bolt stands on the back of a tooth of the five teeth disc, the lever is
so kept out of reach of a driver or cam as to undergo and impart to the click armı

page_text: only a slight movement, that is to say the respective shaft of the chain pulleys is
only so far turned as the small tooth division of the fifteen teeth disc amounts to.
When however the bolt has entered an interstice between two teeth of the five
teeth disc, said driver causes the two-armed lever to be more deflected, whereby
the click arm is carried over one of five larger divisions of the fifteen teeth disc
and the extent of transport of the cards is determined.

A Machine for Tying or Lacing together the Cards used in Jacquard
Machines.
1, GEORG PAULICK, of Bruchl 2, Leipzig, in the Empire of Germany, Clerk,
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 reference to improvements hereinafter described and claimed
in the construction of a machine for tying or lacing together Jacquard cards for
use in Jacquard machines.
Referring to the accompanying drawings,
Fig. 1 is a plan,
Fig. 2 is an end view, and
Fig. 3 is a plan partly in horizontal section on the line cc Fig. 2 of a machine
constructed according to this invention.
A is a stand or frame provided with a table B. C is a shaft carrying a strap.
pulley C¹.
DD are clutches operated by a handle E. F is a cam shaft driven
from the shaft C by the pinions C³, F, and carrying the cams F G and H and the
toothed wheel I. J is a vertical shaft driven from the shaft F, K are the shuttles,
L is a needle bar carrying the needles L. M are springs mounted on the needle
bar L and adapted to clamp the thread as hereinafter described. N are transporting
chains by which the cards to be laced are carried through the machine. 00¹ are
toothed wheels, acted on by a click arm or pawl P and a bolt or stop P' carried by
a crank lever Q, which wheels serve to impart motion to the chains N. R is a
thread tension bar which draws the thread off the spools R*, this bar being actuated
from a rocking lever S. T are springs serving to press the Jacquard cards on the
chains N.
The clutches D D' are situated respectively near the ends of the shaft C. The
clutch D serves to put the machine in and out of gear, while the clutch D¹ serves
to put in and out of gear a band pulley D² for driving a spool winding device D³,
the construction of which will be readily understood from the drawing. The
clutches are moved to and fro by the handle E through the medium of levers, E¹
connected by a rod E, these levers having pins taking into circunferential grooves
in the clutches in the usual manner.
The needles L' are actuated by the cams F1 which act on rollers F2 on needle
sticks or side bars F3 working vertically in brackets F, and carrying the bar L on
which the said needles are mounted.
The shuttles K are carried in a holder K' operated from a crank J' on the
vertical shaft J, through the medium of a connecting rod J. This shaft is carried
in brackets J' and is driven froin the wheel I on the shaft F, which wheel has
inclined teeth and gears with a wheel J* on the shaft J having correspondingly
inclined teeth.
'
In some cases however the shuttles may be operated by a cylindrical piece
mounted preferably on the shaft C and having a cam groove into which a pin on a

page_text: rocking arm enters, this arm being connected with the shuttle holder K and being
rocked by the cam, so imparting reciprocating motion to the shuttles.
The thread clamping mechanism comprises the springs M secured to the needle
bar L and provided with inclined or slanted surfaces M adapted to bear, when the
needle bar is in its lowest position, against a stationary rail M² supported in
suitable brackets whereby the said springs are pressed inward and serve to hold or
clamp the thread.
The clamping fast of the thread is continued for some time when the needle
re-ascends, so that the thread in the needle can pass only in the direction to the
shuttle loop, whereby the loop for the passage of the shuttle is infallibly formed.
The card transporting mechanism, which comprises the chains N, the toothed
wheels O, O the pawl P, bolt P and lever Q, is actuated by the cam G on the
shaft F. The card transporting chains N are carried on chain pulleys N' mounted
on two parallel shafts N, and have studs N³ to engage with holes in the cards.
To take up slackness of the chains one or both of the shafts N2 work in slots N'
so as to permit of the space between them being increased when necessary. The
click-arm or pawl P engages the teeth of the disc while the other disc O'
serves to limit the upward movement of the bolt or slot P¹ the said pawl and the
bolt being respectively pivoted and rigidly secured to one arm of a crank lever Q
pivoted at the other arm of which lever is actuated by the cam G serving to
move the lever in one direction while a spring Q serves to return it after being so
moved. According as the bolt P enters between the teeth of the disc O or bears
upon the back of a tooth, the click arm or pawl P is permitted to rise to a
greater or less extent thereby regulating the amount to which the said pawl rides
over the wheel O and the movement imparted to the respective chain pulleys N'
at each downward movement of the pawl P. These downward movements of the
pawl Peffected by the action of the cam G on a roller Q³ on the crank lever Q,
partially rotate the disc O and with it the disc O' mounted on the same shaft, at
the same time effecting the rotation of the pulleys N' of the card transporting
mechanism. When the cam G in its rotation ceases to act on the lever Q, the
arm against which. it bears is drawn downward by the spring Q2 thereby causing
the pawl to ride up over the teeth of the disc O until the bolt P comes in
contact with the disc O¹ whereby further movement of the lever is arrested until
the cam G again begins to act on the lever.
It will be evident as before mentioned that when the bolt P enters between two
teeth on the disc O' the click arm P will ride over a larger space than if the said
stop came against a tooth, and that when this is the case the downward movement
of the said click arm will impart a greater movement to the wheel and thence
to the card transporting mechanism.
The parts are so arranged that this greater movement occurs at every third
stroke of the crank lever so as to give a feed corresponding with the distances
of the lacing holes in the cards, which are such that the adjacent holes of contiguous
cards are nearer than the two holes in the same card, a short stitch extending
between the second or rearmost hole to the edge of each card, another short stitch
extending to the first hole of the next card and a long stitch extending between
the two holes of this latter card and so on. The wheel O may have its teeth
arranged so that every third tooth is of a larger size than the others, these larger
teeth being adapted to be engaged by the pawl P when the bolt P' enters between
the teeth of the wheel O' in order to give the longer motion to the cards. In the
example shewn however the teeth of the wheel O are all of equal size, the pawl P
at its longer stroke riding over a greater number of teeth than at its shorter stroke.
The relative arrangement of the teeth of the wheels may however be varied
according to the position .the lacing holes occupy in the cards, the teeth being
arranged so as to give the proper feed motion in cases where the stitch required
differs from that above referred to viz., two short stitches alternating with one
long.stitch.

The thread tension which acts to draw the thread from the spools comprises a
bar R carried between the forward extremities of two rocking levers R¹ pivoted
at R2, the rear extremity of one of which is coupled by a connecting rod S' with a
corresponding rocking lever S pivoted at Q' and actuated by the cam H.
The cards to be laced are pressed downwards upon the carrying chains N' by
long springs T secured to the rail M²..
The action of the machine is as follows:-
--
The clutch D being put into gear by the handle E the shaft C. is caused to
rotate by the pulley C whereby the machine is set in motion. The cards to be
laced are fed on to the chains N by the attendant so that the studs N' take into
the cylinder holes in the cards. The cam G then operates the transporting
mechanism and the cards are carried forward by the chain being held thereon by
the springs T and are brought into their proper position under the needles L'
ready for stitching, the parts being shewn more clearly in Fig. 2 in their relative
position prior to the formation of a stitch.
The transporting mechanism then pauses and the click arm P rides up over the
disc ready to impart a further movement, the cams F' permit the needles first to
descend rapidly, and then to rise very slightly while the shuttles K2 are moved
forward. The cams F next by the action of their tangential portion shewn in
Fig. 2 towards the lower left hand side, raise the needles rapidly and afterwards
maintain them by the action of the succeeding segmental portion in their upper-
most position for a time to permit the card transporting movement, the shuttles
being during these movements of the needles, brought back by the continued rotation
of the crank arm J. After the needles have arrived at their uppermost position
the cam G again actuates the transporting mechanism and effects a further forward
movement of the cards ready for the next stitch. With the exception of the feed
wheels O O¹, the parts are thus brought back into the positions shown in Fig. 2
and in the continued operation of the machine the foregoing movements will be
repeated.

It is obvious that machines constructed according to this invention may be
somewhat modified in detail. Thus instead of the single pulley C₁ an arrangement
of fast and loose pulleys may be applied on the end of the driving shaft a suitable
belt shifter being mounted on the table B or otherwise to permit of the driving
belt being moved from one pulley to the other. In some cases a punching apparatus
may be combined with the machine hereinbefore described for the purpose of
punching the lacing holes and the cylinder holes.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :-
