Improvements in Jacquard Machines.
I, FRIEDRICH CARL EIDMANN of Elberfeld, in the Empire of Germany,
Weaver, do hereby declare the nature of this invention to be as follows:-
This invention relates to a process and appliances for disengaging the lifting
wires in Jacquard machines, and the needles connected therewith, together in
greater numbers as is for instance required with the application of the bottom
shoot. Thereby for instance the so-called blind card can be rendered quite
superfluous.
The process consists in placing rods before the single rows of lifting wires and
moving said rods in the direction of the lifting wire to be disengaged. Said rods
are held on both sides by the longitudinal sides of a horizontal frame which are
guided' in cross bars attached to the frame of the loom. To said frame are
revolubly attached the needles which lie over a horizontal knife. The needles have
at their ends hooks so that when they lie on the knife, they are taken along when
the latter moves. By a suitably placed rotary roller the needles can be lifted by
any suitable contrivance and thereby placed above the knife, so that the latter
when moving forward cannot seize the hooks of the needles. Thus the horizontal
frame keeps its place and the lifting wires remain in their normal position i.e. are,
not disengaged when the knife takes along the needles.
The reciprocating movement of the knife is effected direct by the lifting of the
knife basket. On the latter is provided a roll against which lies a lever oscillating
about a pivot and having a projection on the side of the roll. By a spring connected
with the frame that edge of the lever which is provided with the projection is
always drawn against the roll, so that when the knife basket rises, the lever
Oscillates and thereby moves the knife, which is connected with it by rods, in the
same direction. Said draw spring may also be dispensed with, as the springs of the
lifting wires press the lever into its normal position.
The horizontally arranged knife has any suitable guiding or rest on the frame
or may bear with its holding bars on the shaft of the roller lifting the needles.
This shaft has its bearings secured on arms connected with the base frame. The
turning of the shaft i.c. of the roller for lifting the needles. is effected direct by the
lifting of the knife basket by a catch hook which is movably, connected by a pivot
with an oscillating lever, the knife basket being connected with a pivot moving in a
slot of said oscillating lever. This lever is inclined, that is to say its point of
suspension lies sidewise from the direction of movement of the pivot connected
with the knife basket, so that the lever according to the position of its point of
Suspension oscillates to the right or left, causing of the lifting roller to be turned
by the catch hook accordingly. The catch hook presses or draws, in the manner
usual with Jacquard machines, pivots of a disc mounted on the shaft of the roller.
Also the fixing of the roller after turning may be effected in the known manner by
springs pressing on the sides of the square pivot disc.
The needles may be lifted by the roller in various manners for instance by 'lifters
provided thereon, by a lifter chain etc. Or the roller may be quadrangular in

Improvements in Jacquard Machines.
I, FRIEDRICH CARL EIDMANN of Elberfeld, in the Empire of Germany,
Weaver, 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 :-
1
This invention relates to the method and appliances for disengaging the lifting
wires in Jacquard machines, and the needles connected therewith, together in a
greater number, as is for instance required when using the plain or ground weft
(as distinguished from the figured weft or fabric produced by the Jacquard
mechanism). Thereby for instance the so-called blind card can be entirely dispensed
with.
The method consists in placing little rods before the single rows of lifting wires
and moving said rods in the direction of the lifting wire to be disengaged.
Referring to the accompanying drawing illustrating my invention:
Fig. 1. is a section of the improved device along line GH Fig. 6.
'
Figs. 2. 3 and 5.are lateral views thereof, Fig. 3 being an ideal view with regard
to lever k.
Fig. 3 is a top view of two cards, one with cut q', the other without that cut..
Fig. 6 is a section along line ABCD Fig. 1.
Fig. 4 a section along line E F Fig. 2.
Fig. 7 is a plan, in which the lifting, wires can be at pleasure disengaged in rows
by a frame divided in its width into several compartments.
Figs. 8 and 9 are side views, and
Figa. 10 and 11 plans illustrating a contrivance for displacing the roller as
hereinafter described.
The improved device consists of little bars a lying in front of the lifting wires
and held on both sides by the longitudinal sides c¹ and c' of frame c. These sides
are guided in cross bars e and e' secured to the frame d of the loom. To said frame
are revolubly fixed the needles flying over the horizontal knife.g and having at
the end a hook so that, when lying on the knife, they are taken along by the
latter when moving. Through a revoluble roller ' mounted on shaft the needles
can be lifted by means of any suitable contrivance, and thereby placed above knife
so as to prevent the latter seizing, when moving forward, the hooks of the needles,
whereby the whole frame c with rods a is left standing. The lifting wires therefore
retain their normal position i.e. are not disengaged, whereas this is the case when
the knife takes along the needles f
9,
The reciprocating movement of knife g is produced direct by the rising of the
knife basket i which has on it a roller "in contact with a lever k oscillating about
pivot and having a projection k². By a spring l'fixed to frame that edge of
lever which is provided with the projection, is continually drawn against the
roller, so that when knife basket i rises, as indicated by an arrow in Fig. 4, lever
Oscillates in the direction indicated by an arrow Fig. 3. Thereby knife g
which is connected to lever & by rods m moves in the direction designated by arrow m¹
Fig. 6. Spring? may also be dispensed with, as the springs of the lifting wires &
press lever into its normal position.
די
The knife occupies a horizontal position and is suitably guided or carried at the
frame. H may also be supported direct by shaft by the rods m bearing on the
latter.

page_text: Shaft his lodged in bearings and h³ which are secured on an arm'd¹ connected
with the frame'd.
The turning of the shaft or of roller for lifting the needles fis effected direct
by the rising of 'knife basket i through the catch hook n movably connected by
pivots o to lever o oscillating about pivot o: The knife basket is connected with
a pivot moving in a slot of the lever; lever o or slot of occupy an inclined
position that is to say the point of suspension of or of lies sideways from the direction
of movement of pivot ; so that, according to the position of its point of suspension;
lever o swings to the right or left, a corresponding turning of roller h¹ by catch
book n being thereby produced. Said hook presses or draws, in the manner usual
with Jacquard machines; the pivots p of the pivot pulley p mounted on sháft k.
Also the fixing of roller after turning may be produced in the known manner
by springs which prees on the quadrangular sides of pulley p.
The lifting of the needles by roller ' can be produced in different ways, for
instance, by means of lifters provided thereon, a lifter chain, or such like.
This purpose is shewn in the drawing as having been attained as follows:
Roller his quadrangular in length and has moving thereou a small card chain g.
When the diagonal side of the roller occupies the position shewn in Fig. 3, the
card being therefore vertically over the median line of shaft h, the needle, which
previously had been bearing on the horizontally lying side of the quadrangular
roller, will be lifted, therefore removed from the knife, which consequently cannot
take along the frame c. If, however, this is to be done, that is to say, if the
needle is to keep at rest-not to be lifted,- -a cut or recess q'is provided for the
needle in the edges of two adjoining cards q, Fig. 34, so that the needle keeps
lying unmoved on the respective part of roller , which part is at that place turned
round, instead of having the quadrangular shape of the roller.
As may be easily understood, the disengagement of whole rows of needles in any
suitable number may or may not in this manner be effected according to require-
ment by providing, or not providing, the openings g in the card row. Thus the
lifting wires to the figure card, and thereby the latter itself,, may be at will
made to operate or not. When the lifting wires or needles are disengaged by
means of the improved device, the lifting wires lying outside the apparatus are
still at work, by which wires, for instance the plain weft or fabric, borders etc..are
produced in the known manner by means of prism r.
The machine operates as follows:
If the figure card is to act, the improved device must be out of action; on the
rising of the knife basket .therefore the needles must be lifted by the rotation of
roller by means of catch hook n; it is to be observed that the projection. of
lever k is of such a length, that the knife basket has already moved a certain
distance, whereby roller indeed rises at once, while however knife g with the
moving mechanism connected thereto remains for a while unmoved until the hooks f¹
of the needles have come out of reach with the knife by the turning of the roller
or card chain, a card' without notch having come into action; at the further
rising of the knife basket; knife g with its mechanism can then perform its movement
without any influence on the lifting wires, so that on the descent of the knife
basket or of the prism r; the normal operation of the figure card ensues.
If now the figure card is not to act, and the lifting wires serving for the plain
weft etc.. are, to operate, a card with notch 9 must,, with the lifting of the knife
basket on roller h¹, follow the previous card, the figure lifting wires are then
disengaged, while the wires serving for the bottom shoot etc. come into action at
the descent of prism r. These latter wires may, or may not, be brought in
connection (in the same manner as described with the figure wires) with the knife
outside the main contrivance.
1
When no figure card is to operate, naturally the turning of prism is to be
prevented by lilting the respective catch hook; this may be effected by means of
lifting wires, in the well known manner..

page_text: Also the lifting wire rows for the figure cards may be disengaged at pleasure in
rows by single frames c operating separately from and independent of each other, as
shewn in Fig. 7, each of which frames is, or is not, put in connection by a separate
needle with the running-through knife g. Thus a variety of patterns can be
produced with one and the same figure card, according as the single frames. or the
lifting wire rows connected therewith are made to operate.
If roller or the card chain 9 resting thereon, which lifts or lets alone the
needlesso as to lift or not to lift the lifting wires b, is so arranged as to be capable
of displacement and the card chain recessed differently, that is to say if notches
are made therein which are arranged beside each other regularly or irregularly
according to requirement, the making of patterns in fabrics provided with edge
and in which the pattern matches several times in the cut-work can be considerably
simplified, whereby also economy in cards is effected.
Then, for a certain position of roller the border is finished and the roller is so
displaced in order to produce the cut work as to cause the needle to coincide with
other notches of the cards q. When again displacing roller for producing
another border, the notches q' are to be so arranged, that, provided the positions
with the first border are named 1, 2, 3, 4, the positions of the cut work in the
numbers 4, 3, 2, I would follow.
By further displacement of the roller with which corresponding notches q' must
be provided in the card chain q, satin and taffet border can be produced.
Owing to this arrangement, coherent patterns can be produced by placing only
four cards on roller without altering the movement of the small roller.
The said device for displacing the roller is shewn in Figs. 8 to 11. The axis of
roller is lodged in a frame c, in which a shaft is provided which has at the
bottom a handle for being turned. The latter shaft has secured thereon a multiple
lifter, that is to say by means of which different lifts in the same direction can
be effected. By this lifter a slide piece fastened on is, pulled in the direction
indicated by arrow z on shaft z being turned in the same direction. In a groove
of said slide piece, a disc secured on shaft A can so turn as to be compelled to
participate in the movement of the slide piece.
When lifter has completed its revolution and has arrived at its highest lift,
the spring fixed to 2, on further turning of shaft a', draws the slide piece, and
thereby the lifter back into its normal ie. initial position.
To prevent the needles, which may lie in a recess 7' of the card, from hindering
the displacement of roller h¹, said needles are lifted jointly by a lever y revoluble
about pivot y' by means of a cord y running over a pulley y and having a handle y',
said cord influencing pivot y² of lever y.
In Fig. 8 the needles thus lifted are indicated in dotted lines, while, when
occupying the position shewn in full lines,.they lie in one of the displaceable straps
(Fig. 10) of roller h¹ or in a corresponding cut q' of the card chain q.
It may occur, that the whole contrivance cannot be arranged below the spring
box, or that the rods a cannot be laid below the needles owing to want of space or
by other reasons; in such a case the device is laid above the spring box, that is to
say, the rods are made to influence the lifting wires.above the needles.
The little rods a may also be displaced by other suitable devices for influencing
the lifting wires..
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed; I declare that what I
claim is:
1.) In Jacquard machines, the method of disengaging the lifting wires, by means
of littie rods (a) placed between them, from the knife, so as to prevent said wires
from being lifted, substantially as set forth.
2.) The application of the method of disengaging the lifting wires referred to in
Claim 1, when the lifting wires serving for making the plain or ground fabric are

page_text: to be lifted, the whole of the lifting wires appertaining to the figure cards being-
then disengaged, whereby simultaneously the so-called blind cards are dispensed
with, substantially as set forth,
3.) The method of producing the disengagement of the lifting wires referred to.
in Claims 1 and 2, by the corresponding movement of a frame or frames (0) acting
independently of each other, in which the rods (a) are lodged, whereby one or more.
lifting wire rows are disengaged and consequently a variety of patterns can be
produced, according to the combination of the single frames, by means of the same
cards, substantially as set forth.
4.) The method of producing the movement, referred to in Claim 3, of frame (c).
by means of needles (f) and a reciprocating knife (9), which causes at will the.
needles.to take part in its movement or leaves them unmoved according as they are
in connection with said knife or not, substantially as set forth.
5.) The method of suspending, or not suspending, the connection, referred to in
Claim 4, of the needles (f) with a knife (9) by the turning of a lifting roller, the.
needles being, or being not, lifted by the same.
6.) The method of producing the reciprocating movement of the knife (9) by
means of a roll (2) levers (k) oscillating about pivots (¹), slide rods (m) and, if
desired springs (1), substantially as set forth.
7.) The method of producing the turning referred to in Claim 5, of the lifting-
roller by a catch hook (n), a lever (o) with slot (o) oscillating about a pivot (o' or o³)
and a pivot (3) adapted to move in said slot and connected to the knife basket (i),.
the turning of the lifting roller (¹) taking place in the one. or in the opposite
direction, according as the turning pivot of the lever is located on the left or on
the right over the pivot (a) of the knife: basket (i), substantially as set forth.
8.) The method of producing the lifting or non-lifting, referred to in Claim 5, of
the needles (f) during the turning of the lifting roller (¹), by means of a card
chain and notches q¹ therein, substantially as set forth.
9.) In the arrangement forming the subject of Claims 1 to 8 the displacing of
the roller (h) or of the card chain (9) connected thereto, for the purpose of pro-
ducing thereby without turning of the card chain an alteration in the initiatory
action of the needles (f) and thereby in the lifting of the lifting wires (b)
substantially as set forth.
10.) The method of effecting the displacement of the roller (h¹) referred to in
Claim 9 by means of shaft r' with lifter, slide piece. with connecting piece.
spring and disengaging lever y, substantially as set forth.
