IMPROVEMENTS IN JACQUARD MACHINERY
Year: 1884

page_text: I JULES VERDOL Mechanical Engineer of Paris in the Republic of France do
hereby declare the nature of the said Invention for IMPROVEMENTS IN JACQUARD
MACHINERY to be as follows:-
.
The new machine constituting the object of my Invention is designed to
facilitate the substitution of paper for card in jacquard machines and is
characterized by the combination in a single machine of the jacquard and of the
cylinder mechanism as also by new arrangements in the cylinder mechanism. which
secure the perfection of my work.
This combination has enabled me to give to the entire arrangement a great
stability and a solidity which diminish the chances of disarrangement of the
operating parts.
an
In the employment of paper in lieu of card in jacquard machines
inconvenience exists which can scarcely be avoided, but which nevertheless can be
greatly reduced, I refer to the influence of the hygrometric condition of the
atmosphere upon the paper.
I have succeeded in reducing this influence almost to nothing.
To obtain this result I reduce the width of the paper to its smallest possible
amount by means of new arrangements which I have devised and which I will
now describe.
The humidity of the atmosphere acting therefore no longer except upon a compara-
tively very narrow paper the distortion of the latter becomes inappreciable.
The accompanying Drawings contain the following Figures.
Figure 1 represents a side view of my new machine.

Figure 2 is a vertical section drawn through the axis parallel to the needles of
the jacquard.
Figure 3 is a face view of part of the series of bars or metallic card acting only
on the jacquard.

serving to catch the small vertical juxtaposed needles.

page_text: The two opposite sides of the cast iron framing parallel to the direction of the
needles of the jacquard each support a carriage C capable of sliding in guides.
The forward motion is given to the carriages by a cranked rod z' formed with
two vertical limbs connected together by an inclined piece and guided by two small
pulleys g, g' on horizontal axes and to which rod a rising motion is given by the
griff G, of the jacquard upon which the rod Z' is fixed.
These two carriages carry at their rear ends a re-adjusting board R¹ for the
needles of the jacquard and at their forward ends the series of bars B, which
act upon the needles of the cylinder mechanism.
In front of the readjusting board R' is placed the needle case which is formed
by 17 plates or rods upon which the ends of the needles i slide.
Each carriage is in two parts which facilitates, by means of a screw and nuts V,
the regulation of the position of the series of bars B.
Upon the sides of the bronze frame of the series of bars, are fixed by nuts, and
lock nuts, the ends of the horizontal cranked rods Z2, which take the horizontal
motion which the series of bars receives from the carriages and which carry with
them in their motion a readjusting board R2, for the needles of the cylinder
mechanism which readjusting board R2, is fixed to the rear ends of these cranked
rods Z³. These cranked rods impart by their central inclined parts a vertical
motion to two vertical slides a by means of pulleys g³, g, fixed upon these slides..
A bronze needle guide D perforated, as I will hereafter describe, and in which
are engaged the vertical needles b of the cylinder mechanism, is fixed to the lower
ends of the slides a.
To the upper ends of these same slides is fixed a re-adjusting board R³ for the
same needles.
The needle guide D and the re-adjusting board R³ take therefore at the same
time as the vertical slides a a vertical motion the extent of which is about four
and a half millimeters.
The entire of the cylinder S suspended on the one hand to the framing by
hooks o¹ and on the other hand to the bar D by hooks c², takes also a vertical
motion of the same extent as the bar D in consequence of the union existing
between the latter and the cylinder by the hooks c².
The space existing between the bar D and the plate of the cylinder remains
therefore invariable and is about one and a quarter millimeters for the passage of
the paper.
The paper passing over the plate P is guided by discs & furnished with studs r
corresponding with the holes perforated in the paper card and by the plate t fixed
behind the bar D.
At each motion of the jacquard the discs d make a ninth of a revolution and
consequently cause the paper to advance by a card by means of clicks or drivers h
acting upon the spindles of the lantern which clicks or drivers receive their
motion from the action of a cranked rod Z³ upon a pulley g5 placed at the extremity
of the lever m.
The motion of the lantern is regulated by a roller ge whose strong pressure
upon two consecutive spindles of the lantern is obtained by means of a spring p
fixed under the cross bar T which unites the two extreme supports of the cylinder.
The forward or backward motion of the cylinder carrying the paper card is
regulated by the aid of the rocking lever q which acts to throw one or other of the
clicks or drivers h out of action.
The end of the spring p is connected by a small connecting rod K to the end of
the lever L upon which is fixed the axis of the roller g*.
The entire of the cylinder, that is to say the plate P, the discs d, the lantern l,
and their shaft, the roller go, and its lever L, can be separated from the rest of the
apparatus..
To effect this it is only necessary to withdraw the hooks c' in front, and the
system remains suspended by the hooks o' from the cross bar e.

page_text: This dismounting enables the ready application of the paper upon the discs d
and the plate P.
When a vertical ascending motion is given to the griff of the jacquard the
carriages receive through the action of the cranked rods Z', a horizontal move-
ment and take with them in this motion, on the one side, the readjusting board R¹
for the needles. i of the jacquard placed at the back, and on the other side, the
series of bars B, placed in the front. This series of bars B carries with it in its
horizontal motion the re-adjusting board R' of the needles b of the cylinder
mechanism by the intervention of the horizontal cranked rods Z³. These cranked
rods Z give a vertical motion to two vertical slides a which transmit their rising
and falling motions to the re-adjusting board R³ of the vertical needles 6 of the
cylinder mechanism placed at the top of the apparatus and also to the bar D into
which the vertical needles are threaded as also to the entire system composing the
cylinder S.
The bronze plate H of the jacquard is perforated with 1248 holes. These holes
are arranged upon one, two, three or more similar parts, this number being capable
of variation according to the requirements of manufacture.
Each similar part contains 416 holes placed in 16 vertical rows and 26 horizontal
rows...
A little further in front another fixed plate O of sheet iron parallel to the
preceding is perforated in an entirely similar manner.
It affords passage to the back ends of the horizontal drivers ; of the cylinder
mechanism. Between the two foregoing plates which are fixed, another parallel
plate can move from front to back and the reverse; this is the re-adjusting
board R' receiving a horizontal motion from the cranked rods Z. This last board
or plat is perforated as the foregoing with a similar number of holes but slightly
larger, arranged in the same manner.
.These holes of the three plates H, R³, and O correspond with each other and are
consequently placed upon the same horizontal lines.
Between the fixed plate O and the readjusting board R2 the horizontal drivers j
of the cylinder mechanism effect the thrust upon the corresponding needles i of
the jacquard. These drivers of the cylinder mechanism engage in front in the
series of bars after having passed through the eyes of the vertical needles b.
This series of bars is composed of 17 horizontal bars having a section of the
form of an angle with unequal wings and the smallest wing of which is vertical
and gives the thrust upon the drivers. A vertical .row of 16 of these pushers
corresponds to two parallel rows of eight vertical needles.
.
The reduction in length and in width of the card has caused me to perforate the
paper with holes arranged in zigzag lines.
In this manner the card is reduced to its smallest possible dimensions in length
and in width without nevertheless diminishing the resistance of the paper.
The paper having a very reduced width, it results therefore that the influence of
the hygrometric condition of the surrounding atmosphere becomes one might say
inappreciable which ensures in a perfect manner the coincidence of the holes in
the paper card with the needles of the cylinder mechanism and consequently
produces a great exactitude in the work.
This arrangement of holes in zigzag lines having for its object a sufficiently
close arrangement of the vertical needles amongst themselves I have been obliged
to give to the. upper grille or grating which holds the ends of these needles a
special form of perforation, in order that the rising and falling motions of the
needles may not be obstructed in consequence of their close arrangement. This
grille or grating is represented on the Drawing Figure 5 to a large scale.
Another new arrangement which I have applied in my machine consists in the
movement of the vertical needles of the cylinder mechanism.
It is these needles which by means of eyes v conveniently placed, raise the
horizontal drivers which are required to abut against the bars of the series of..
bars B.

'
In place of giving to these needles a falling motion which enables the working
needles to pass through the paper and to bring the corresponding horizontal
drivers in front of the spaces of the series of bars so that they may not be then
pushed back, I give on the contrary a rising motion to the cylinder and consequently
to the paper by means of the slides a.
The working needles pass through the paper by resting immoveable; the others
encountered by the substance of the paper are raised and thereby cause the ends
of the corresponding horizontal drivers to be placed in front of the bars of the
series of bars whilst the others remain in front of the spaces.
This new motion secures the following advantages:
When the needles have produced their effect, they are all brought back to their
primitive position.
Each vertical needle raised falls again by its own weight aided by a part of the
weight of the horizontal driver engaged in its eye.
But if, by any cause whatever, say by a resistance arising from friction, one of
these needles should not fall it is nevertheless forcibly replaced in its first position
by the re-adjusting board R³.
This new essential arrangement is very important, because it absolutely prevents
any idle needles. There will result from this an absolute certainty in the
regularity of the work of the needles and consequently the obtainment of a
perfectly manufactured product.
The operation of the machine has been previously described at the same time
as the construction of the machine. But that which I greatly desire to establish,
is the entirely novel and very essential arrangement consisting in causing the
paper to act upon the vertical needles of the cylinder mechanism in place of
causing the latter to act on the paper which gives me the possibility of preventing
all misses in the working of these needles by the re-adjusting board R³ which
brings them all back without exception to their primitive position.
Further the re-adjusting boards R2 and R' acting the one upon the needles of
the cylinder mechanism and the other upon the needles of the jacquard, have the
effect of replacing at the commencement of each motion, all the needles in their
normal position with certainty.
These arrangements combined with the reduction of the dimensions of the
paper cards and the union in a single body of the cylinder mechanism with the
jacquard, form a combination which ensures the absolute regularity of the work
and the obtainment of a product manufactured with a perfect execution.
This machine can be varied in the forms, materials and dimensions of the parts
according to the number of needles necessary for the manufacture of the material
it is desired to produce.

described and ascertained in and by the following statement:-
The new machine constituting the object of my Invention is designed to facilitate

as also by new arrangements in the cylinder mechanism which secure the perfection

I have succeeded in reducing this influence almost to nothing.
To obtain this result I reduce the width of the paper to its smallest possible
amount by means of new arrangements. which I have devised and which I will now
describe.
The humidity of the atmosphere acting therefore no longer except upon a
comparatively very narrow paper the distortion of the latter becomes inappreciable.
The accompanying Drawings contain the following Figures.
Figure 1, represents a side view of my new machine.
Figure 2, is a vertical section drawn through the axis parallel to the needles of
the jacquard.
Figure 3, is a face view of part of the series of bars or metallic card acting only.
on the jacquard.
Figure 4, represents the arrangement of the holes of my new card.
Figure 5, represents the arrangement of perforation of the grille or grating
serving to catch the small vertical juxtaposed needles.
Figure 6, represents a separate view of two vertical juxtaposed needles.
Figure 7, is a plan view of the rear end of a needle i of the jacquard together
with the stop pin and a view of the end which pushes back a griff.
The two opposite sides of the cast iron framing parallel to the direction of the
needles of the jacquard each support a carriage C capable of sliding in guidės.
The forward motion is given to the carriages by a cranked rod Z¹, formed with
two vertical limbs connected together by an inclined piece and guided by two
small pullies g, g¹, on horizontal axes and to which rod a rising motion is given by
the griff G, of the jacquard upon which the rod Z', is fixed.
These two carriages carry at their rear ends a readjusting board R¹, for the
needles of the jacquard and at their forward ends the series of bars B, which act
upon the needles of the cylinder mechanism.
In front of the readjusting board R¹ is placed the needle case which is formed
by 17 plates or rods upon which the ends of the needles i slide.
Each carriage is in two parts which facilitates, by means of a screw and nuts V,
the regulation of the position of the series of bars B.
Upon the sides of the bronze frame of the series of bars are fixed by nuts and.
lock nuts the ends of the horizontal cranked rods Z2, which take the horizontal
motion which the series of bars receives from the carriages and which carry with

page_text: them in their motion a re-adjusting board R2, for the needles of the cylinder
mechanism which re-adjusting board R² is fixed to the rear ends of these cranked
rods Z³.
These cranked rods impart by their central inclined parts a vertical motion to
two vertical slides a by means of pulleys g³g fixed upon these slides.
A bronze needle guide D, perforated as I will hereafter describe and in which are
engaged the vertical needles 6 of the cylinder mechanism, is fixed to the lower ends
of the slides a.
To the upper ends of these same slides is fixed a readjusting board R³ for the
same needles.
The needle guide D, and the re-adjusting board R³, take therefore at the same
time as the vertical slides a a vertical motion the extent of which is about four
and a half millimeters.
The entire of the cylinder S suspended on the one hand to the framing by
hooks c¹ and on the other hand to the bar D by hooks c2 takes also a vertical motion
of the same extent as the bar D in consequence of the union existing between the
latter and the cylinder by the hooks c².
The space existing between the bar D and the plate P of the cylinder remains
therefore invariable and is about one and a quarter millimeters for the passage of
the paper.
The paper passing over the plate P is guided by discs & furnished with studs r
corresponding with the holes perforated in the paper card and by the plate t fixed
behind the bar D.
At each motion of the jacquard the discs & make a ninth of a revolution and
consequently cause the paper to advance by a card by means of clicks or drivers h
acting upon the spindles of the lantern t which clicks or drivers receive their
motion from the action of a cranked rod Z³, upon a pulley 95 placed at the extremity
of the lever m.
The motion of the lantern is regulated by a roller 96 whose strong pressure upon
two consecutive spindles of the lantern is obtained by means of a spring p fixed
under the cross-bar T which unites the two extreme supports of the cylinder. The
forward or backward motion of the cylinder carrying the paper card is regulated by
the aid of the rocking lever q which acts to throw one or other of the clicks or
drivers out of action.

The end of the spring p is connected by a small connecting rod K, to the end of
the lever L, upon which is fixed the axis of the roller go.
The entire of the cylinder, that is to say the plate P, the discs d, the lantern
and their shaft, the roller go and its lever L, can be separated from the rest of the
apparatus. To effect this it is only necessary to withdraw the hooks c² in front
and the system remains suspended by the hooks c¹ from the cross bar e. This
dismounting enables the ready application of the paper upon the discs d and the
plate P.
When a vertical ascending motion is given to the griff of the jacquard the
carriages receive through the action of the cranked rods Z¹ a horizontal movement
and take with them in this motion on the one side the readjusting board k¹ for
the needles i of the jacquard placed at the back and on the other side the series of
bars B, placed in the front. This series of bars B carries with it in its horizontal
motion the re-adjusting board R², of the needles b of the cylinder mechanism by
the intervention of the horizontal cranked rods Z². These cranked rods Z2, give a
vertical motion to two vertical slides a which transmit their rising and falling
motions to the readjusting board R³, of the vertical needles b of the cylinder
mechanism, placed at the top of the apparatus, and also to the bar D, into which
the vertical needles are threaded as also to the entire system composing the
cylinder S.
The bronze plate H, of the jacquard is perforated with 1248 holes. These holes
are arranged upon one, two, three or more similar parts, this number being capable
of variation according to the requirements of manufacture.

page_text: Each similar part contains 416 holes placed in 16 vertical rows and 26 horizontal
rows.
A little further in front another fixed plate O, of sheet iron parallel to the
preceding is perforated in an entirely similar manner. It affords passage to the
back ends of the horizontal drivers j of the cylinder mechanism...
Between the two foregoing plates which are fixed another parallel plate can move
from front to back and the reverse; this is the readjusting board R² receiving a
horizontal motion from the cranked rods Z2. This last board or plate is perforated
as the foregoing with a similar number of holes but slightly larger arranged in the
same manner.
These holes of the three plates H, R2, and O, correspond with each other and aro
consequently placed upon the same horizontal lines.
Between the fixed plate O, and the readjusting board R2, the horizontal drivers j
of the cylinder mechanism effect the thrust upon the corresponding needles i of the
jacquard.
These drivers of the cylinder mechanism engage in front in the series of bars
after having passed through the eyes of the vertical needles b.
This series of bars is composed of 17 horizontal bars having a section of the
form of an angle with unequal wings and the smallest wing of which is vertical
and gives the thrust upon the drivers. A vertical row of 16 of these pushers
corresponds to two parallel rows of eight vertical needles.
The reduction in length and in width of the card has caused me to perforate the
paper with holes arranged in zigzag lines.
In this manner the card is reduced to its smallest possible dimensions in length
and in width without nevertheless diminishing the resistance of the paper.
The paper having a very reduced width, it results therefore that the influence of

a great exactitude in the work.
This arrangement of holes in zigzag lines having for its object a sufficiently closo
arrangement of the vertical needles amongst themselves I have been obliged to give
to the upper grille or grating x which holds the ends of these needles a special
form of perforation, in order that the rising and falling motions of the needles inay
not be obstructed in consequence of their close arrangement. This grille or grating
is represented on the Drawings Figure 5 to a large scale.
Another new arrangement which I have applied in my machine consists in the.
movement of the vertical needles of the cylinder mechanism. It is these needles
which by means of eyes conveniently placed raise the horizontal drivers which
are required to abut against the bars of the series of bars B.
In place of giving to these needles a falling motion which enables the working
needles to pass through the paper and to bring the corresponding horizontal drivers

the paper by means of the slides a. The working needles pass through the paper
by resting immovable; the others encountered by the substance of the paper are
raised and thereby cause the ends of the corresponding horizontal drivers to be
placed in front of the bars of the series of bars whilst the others remain in front of
the spaces.
This new motion secures the following advantages.
When the needles have produced their effect, they are all brought back to their
primitive position. Each vertical needle raised falls again by its own weight
aided by a part of the weight of the horizontal driver engaged in its eye.

effect of replacing at the commencement of each motion, all the needles in their
normal position with certainty.
These arrangements combined with the reduction of the dimensions of the paper
cards and the union in a single body of the cylinder mechanism with the jacquard,
form a combination which ensures the absolute regularity of the work and the
obtainment of a product manufactured with a perfect execution.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is,
1. The machine which I have just described by the aid of the accompanying
Drawings. This machine having for its object the substitution of paper for card
in jacquard machines is characterized by the grouping of all the working parts
upon the same framing or the combination in a single body of the jacquard and the
cylinder mechanism.
2. I further claim as my Invention the following new arrangement consisting of
1. The arrangement of the motions in such manner that the needles which pass
through the paper are rendered immoveable whilst the others are raised.
2. The upper re-adjusting board R³, which forcibly depresses all the needles
which have been raised in order to replace them in their primitive position.
3. The perforation of the holes in the guide bar D, the plate P and the paper in
zigzag lines.
4. The special form of the upper grille or grating with which it is possible to
receive all the ends of the vertical needles without the possibility of obstruction in
their motion.
This machine can be varied in the forms, materials and dimensions of the parts
according to the number of needles necessary for the manufacture of the material it
is desired to produce.
