page_text: LETTERS PATENT to Jacques Rives, of No. 15, Rue des Enfants Rouges,
Paris, in the Empire of France, for the Invention of "IMPROVEMENTS IN
LOOMS FOR WEAVING, AND IN PREPARING CARDS FOR THE SAME."
Sealed the 4th October 1861, and dated the 3rd August 1860.
PROVISIONAL SPECIFICATION left by the said Jacques Rives at the
Office of the Commissioners of Patents, with his Petition, on the. 3rd.
August 1860.
I, JACQUES RIVES, of No. 15, Rue des Enfants Rouges, Paris, in the Empire
of France, do hereby declare the nature of the Invention for "IMPROVE.
MENTS IN LOOMS FOR WEAVING, AND IN PREPARING CARDS FOR THE SAME," to be as
follows:-
In the Specification of a Patent granted to me on the 24th October, 1855,
(No. 2377,) was described a loom in which the cylinder carrying the jacquard
cards was carried by a lever and the cylinder was moved to and from the
jacquard needles by this lever; the cylinder was caused to make a partial
revolution each time that it receded from the needles by the cylinder having
projecting from one of its end's six or other number of pins according to the.
number of sides of the card cylinder, and by a hook hinged to the framing
taking hold of one of the pins each time that the cylinder came up to the
[Price &d]

page_text: needles, and one point of the periphery of the cylinder being thus retained
from moving as the cylinder receded it was caused to turn on its axis; this
arrangement is similar to arrangements heretofore proposed.
Now according to my present Invention, in place of hinging the hook to
the framing it is hinged to one end of a bar, which at its other end is con-
nected to one arm of the bell crank lever, the other arm of this lever is so
placed that the lifting bar(which raises the hooks of the jacquard apparatus),
as it descends comes in contact with it, and depresses it. The bell crank being
thus caused to turn ou its centre draws back thebar carrying the hook,and as
the cylinder is receding at the same time that the lifting bar descends, the
cylinder is caused to rotate both by the backward movement of the cylinder
and also by the movement of the hook. As the cylinder again approaches the
needles the lifting bar rises and moves away from the bell crank, the bar
.carrying the hook is then moved forward to take hold of a fresh pin on the
cylinder by a spring pressing the crank to its original position. By this means
the distance through which it is necessary to move the cylinder is diminished,
and consequently the blow on the jacquard needles is also diminished. In
order to be able to move the cylinder in either direction I mount on the bar
moved by thebell crank lever two hooks one to come above the cylinder, and the
other below,and these hooks are so mounted on the bar that eitherone or other
can be caused to take hold of the pins on the cylinder, and the cylinder can
thus be moved in either direction. In the Specification of the Patent above
referred to, the needles upon which the cards on the card cylinder acted were
each brought back to their original position by means of springs, ench
needle having a spiral spring around it for that purpose. Now, in addition
to providing each needle with a spiral spring,I place at the back of the needles
a plate attached to a rod which passes from the back of the needle to beyond
the front of the needles; this rod is furnished with a spring which tends con-
stantly to press the plate against the backs of the needles and so keep the
needles in their forward position. When the card cylinder approaches the
needles one of the projecting pins on the side of the cylinder, which serve as
teeth to keep the cards in position, comes in contact with the end of the rod
and presses it back, and thus presses back the plate at the back of the needles,
and the needles are thus left free to be acted on by the cards. When the
cylinder recedes the plate at the back of the needles is by its spring brought
back to its original position and brings back with it the needles which have
been pushed back by the card cylinder. By this means the needles are all
brought back to their original position, even if any of the spiral springs

page_text: with which each of the needles is furnished should get out of order. Some-
times if the card cylinder is moved by the workman in jerks the cards are
caused to jump and thus they sometimes get out of gear with the pins
projecting from the sides of the cylinder. Now in order to prevent the cards
thus getting out of gear with the cylinder I embrace the upper half of each
end of the cylinder with the arc of a circle, between which and the cylinder
there is sufficient space to allow the cylinder to rotate freely, but there is
not sufficient space to allow the cards to get off the pins.
It sometimes happens that the jacquard cylinder of looms is either not
sufficiently rotated by the workman, or else is rotated too far, so that the
cylinder does not present a flat face to the needles, and imperfect work is thus
produced.
Now in order to prevent the card cylinder acting on the needles unless
it is properly rotated, I place a stop on the framing, against which, if the
cylinder is not properly rotated, one of the pins which project from the end of
the cylinder, and by which the cylinder is rotated, as above described, comes
in contact, and so prevents the needles being acted on; but when the cylinder
is properly rotated, the pin on the cylinder is received into a slot in the stop,
so that the cylinder may move up to and act on the needles. In place of con-
necting together jacquard cards in the ordinary manner, I connect them
together by strips of metal bent to an oval form thus O; the strips of
metal being first passed through small slots near the sides of the cards, and
then bent over, as shewn above.
In the Specification of the Patent above referred to, a machine was
described for punching the holes in the jacquard cards, which consisted of a
number of punches set together in a frame, there being a separate punch for
every hole that might have to be formed in the cards, and each punch was
furnished with a spring, by which it was constantly pressed upwards. The
card to be punched was supported on a barrel or cylinder below the punches,
and when punching the holes in the cards the punches corresponding to the
holes to be made were each knocked down separately by a blow, and so caused
to pierce the card.
Now according to this Invention, I place above the tops of a number of
punches arranged as above described, a plate having formed through it a
number of holes corresponding to the tops of the punches, so that when the
heads of the punches are opposite the holes in the plate, the plate may be
depressed without depressing any of the punches; but when the heads of any
of the punches are moved so as not to be opposite their corresponding holes

page_text: in the plate, when the plate is caused to descend, those punches that have
been moved will be pressed down likewise, and caused to pierce the card. In
order to be able to move any of the punches, each punch near its upper end
is attached by a rod to one arm of a bell-crank lever; the bell-crank levers
are arranged side by side on a fixed rod, around which they are capable of
turning, and between each of the levers there is a spring, so that any of the
levers may be moved without moving the levers on either side of it. The
other arms of the bell-crank levers form keys, and by depressing any of the
keys and so turning the bell-crank on its centre, the punch to which the crank
is connected will be moved, so that its head will not be opposite its hole in the
plate. The pattern to which the cards are to be punched, and which is usually
drawn on paper, divided into into a number of small squares, some of which
are colored, and the others plane, is supported on a table just below the arms
of the bell-crank levers, which act as keys. The squares on the pattern are
of the same width as the key, so that there is a square of the pattern just
opposite each key. In order to arrange the punches so as to punch holes in a
card to correspond with the pattern, the workman depresses those keys which
are opposite either the colored or uncolored squares of the pattern; the plate
above the punches is then depressed, and those punches that have been moved
will be caused to pierce the card below them. The punches are then moved
back to their original position. The pattern surface is by means of clips moved
forward so as to bring a fresh row of squares in front of the keys, and the chain
of blank cards is also moved forward, so as to bring a fresh card under the
punches, when the same operation is repeated. In order to bring back the
punches after they have been moved to their original position, I place above
the ends of the arms of the bell-crank levers to which the punches are con-
nected, and parallel with the axis on which the levers turn, a roller having
projecting from it a tooth, which extends the whole length of the roller, and
when it is required to bring the punches to their original position, the roller is
caused to turn, so as to bring the tooth upon it against the ends of the arms of
the bell-crank levers, and move them all to their original positions. In some
cases, in a set of cards, a number of cards are required to be of the same
pattern, and when such is the case, in order to save the time required for
depressing each of the keys separately, as above described, I arrange aloug
the roller above the bell-crank levers a number of moveable projections or
teeth, there being one such tooth for every bell-crank lever; each of these
teeth can either be caused to project from the roller, so as when the roller is
turned on its axis to come in contact with the bell-crank levers, and so move

page_text: the punches, or may be turned down flat on to the roller, so as not to come in
contact with the bell cranks. By this means by causing only those teeth
which are required to act on the bell cranks to project from the roller by
merely causing the roller to turn on its axis, the punches will be suitably
arranged for piercing the card, and by turning the roller back again in the
opposite direction, the fixed tooth on the roller will be caused to act on the
levers, and bring them to their original position, as above described. The
plate above the needles may be depressed by an eccentric or cam on an axis
above the plate, or by a screw, or otherwise. In order, when one set of cards
has been punched, according to the pattern to be produced, to be able to make
several sets of cards to correspond with it, I arrange a machine in the
following manner :-The set of cards which is to be copied is supported on a
cylinder similar to the jacquard cylinder of a loom, and this cylinder is moved
to and from a set of needles similar to the jacquard needles. Each of these
needles is connected to one of a set of punches arranged in a similar manner
to that just described, except that the heads of the punches in place of being
opposite the holes in the plate, are in such a position that they would all be
depressed by the plate if they were moved before the plate descended. When
the card cylinder comes up to the needles, those needles which are opposite
the holes in the card presented to them will not be acted on, but the other
needles will be pressed back by the card, and this movement will bring the
heads of the punches to which they are connected opposite their holes in the
plate, so that when the plate descends those punches that have been moved
will not be acted on, but the other punches will be depressed and caused to
pierce one of a set of cards below them. The cylinder each time that it recedes
from the needles is caused to partially rotate, so as when it again approaches
the needles to present a fresh card to them, and before the punches are again
depressed the set of cards beneath them is moved forward, so as to bring a
fresh blank card under the punches.

Letters Patent.
upon
NOW KNOW YE, that I, the said Jacques Rives, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in.and by the following
statement thereof, that is to say :-
In the Specification of a Patent granted to me on the 24th October 1855,
(No. 2877), was described a loom, in which the cylinder carrying the jac-
quard cards was carried by a lever, and the cylinder was moved to and from
the jacquard needles by this lever; the cylinder was caused to make a partial
revolution each time that it receded from the needles bythecylinder, having pro-
jecting from one of its ends six or other number of pins according to the number
of sides of the card cylinder, and by a hook hinged to the framing taking hold
of one of the pins each time that.the cylinder.came up to the needles, aud one
point of the periphery of the cylinder being thus retained from moving as the
cylinder receded it was caused to turn on its axis; this arrangement was similar
to arrangements heretofore proposed.
Now, according to my present Invention, in place of hinging the hook to
the framing it is hinged to one end of a bar, which at its other end is con-
nected to one arm of a bell-crank lever; the other arm of this lever is so
placed that the lifting bar (which raises the hooks of the jacquard apparatus)

page_text: as it descends comes in contact with it and depresses it, the bell crank being
thus caused to turn on its centre draws back the bar carrying the hook, and
as the cylinder is receding at the same time that the lifting bar descends the
cylinder is caused to rotate both by the back ward movement of the cylinder;
and also by the movement of the hook; as the cylinder again approaches the
needles the lifting bar rises and meves away from the bell crank, the bar
carrying the hook is then moved forward to take hold of a fresh pin on the
cylinder by a spring pressing the crank to its original position; by this means
the distance through which it is necessary to move the cylinder is diminished,
and consequently the blow on the jacquard needles is also diminished. In
order to be able to move the cylinder in either direction I mount on the bar
moved by the bell-crank lever two hooks, one to come above the cylinder and
the other below, and these hooks are so mounted on the bar that either one or
other can be caused to take hold of the pins on the cylinder, and the cylinder
can thus be moved in either direction. In the Specification of the Patenr
above referred to, the needles upon which the cards on the card cylinder acted
were each brought back to their original position by means of springs, each
needle having a spiral spring around it for that purpose. Now in addition to
providing each needle with a spiral spring I place at the back of the needles
a plate attached to a rod, which passes from the back of the needles to beyond
the front of the needles; this rod is furnished with a spring, which tends con-
stantly to press the plate against the backs of the needles, and so keep the
needles in their forward position. When the card cylinder approaches the
needles one of the projecting pins on the side of the cylinder, which serve as
teeth to keep the cards in position, comnes in contact with the end of the rod
and presses it back, and thus presses back the plate at the back of the needles,
and the needles are thus left free to be acted on by the cards; when the
cylinder recedes the plate at the back of the needles is by its spring brought
back to its original position, and brings back with it the needles which have
been pushed back by the card cylinder. By this means the needles are all
brought back to their original position, even if any of the spiral springs with
which each of the needles is furnished should get out of order.
Figure 1, Sheet 1, shews a side view partly in section of an arrangement of
jacquard apparatus, with the improvements above described applied thereto.
B, B, is an iron framing; the rings A, A, A', A', serving to unite the frame
together; c, c, are two copper plates, which carry the jacquard needles; P is
a lever suspended at its upper end from the framing B; this lever P carries
the jacquard cylinder; F is a bar carrying the griffe or claw, and also the

page_text: roller o, which works in the inclined slot d³, d¹, in the lever P; n is a con-
njecting rod, connected at one end to the axis of the roller o, and at the other
to the lever L; e, e, is a hexagon called the jacquard cylinder; on the axis of
this cylinder is a wheel a, in the periphery of which are six notches r, 71, 71,
and projecting from the side of the wheel are six pins i, , "; F¹ is a bell-
crank lever, the end of one arm of which catches in the notches in the wheel
a; and when this catch is in one of the notches the card cylinder is prevented
from rotating; c,c",are hooks carried by the rod T,which is connected to a bell
crank V, to this lever is attached a spring R, which tends constantly to turn
the lever on its centre o, and keep one of its arms k against the stop 9 when
the griffe or claw F is no longer acting upon it; at the back of the jacquard
needles (two of which are shewn in plan at Figure 6), is a plate t,t, which is
carried by a rod u, u, the end of which is opposite one of the pins a, a¹, a¹¹,
which serve as teeth to cause the chain of cards to move when the card
cylinder is rotated; on the rod T is a spiral spring, which tends constantly
to press the plate t, t, against the backs of the needles. The action is as
follows: When the lever Lis acted on so as to raise the griffe or claw F, the
roller o acts on the inclined slot in the lever P, and so moves the card cylinder
up to the points of the needles; one of the pins a, a', a", then comes against
the front end of the rod u, u, and the plate t carried by it is moved away from
the back of the needles, and the needles are thus left free to be acted upon by
the cards on the card cylinder, consequently all those which are opposite open
holes in the cards remain stationary, as also the hooks with which they are
connected; the rest of the needles, however, are pushed back together with
the hooks connected to them, and as the griffe or claw F continues to rise it
comes against the hooks which have not been moved from their first position
and raises them, and consequently raises the cords attached to them; these
cords in place of passing through a grating composed of rods of small diameter
pass through a grating D, D¹, which is formed in such manner that the cords
rub upon a curved surface forming part of the circumference of a circle of
large diameter, as shewn by the circle A", by which means the friction on the
cords is much diminished. As the griffe or claw is rising and the card cylinder
is acting on the needles, the lever V no longer being depressed by the griffe or
claw turns on its axis until its arm k rests against the stop 2, and the hook c',
which before was embracing the pin i, passes over the pin 2, in order that
when the cylinder recedes it may be caused to rotate, at the same time the
lever catch F¹ comes against the stop N, which causes the other end of the
lever to be disengaged from the notches in the cylinder. These different

page_text: movements take place whilst the griffe or claw Fis rising, but when the lever
Lis moved so as to cause the griffe or claw to-descend, the roller o acts on
the inclined groove of the lever Pand causes the card cylinder to recede from
the needles, at the same time the griffe or claw F.presses down the arm k of
the bell crank V, and thus draws back the hooks, which causes the card
cylinder to rotate on its axis until the catch Fdrops into the next.notch in the
wheel a; the receding' of the card cylinder also allows the platert, t, tosbe
drawn by its spring against the backs of the needles and thus ensures all the
needles returning to their former"position: Ifitis desired to cause the card
cylinder to rotate in the opposite direction the-book. c is moved, so that it
shall no longer act on the piñsi, '; and the hook c" is moved into position to
act on the pins.
Figure 2 shews a jacquard apparatus; such as is abové described, arranged
for working with two card cylinders and two sets of needles; the only pointin
which this apparatus differs from the one above described is in the manner of
giving motion to the roller o in this arrangement the.bars F, which carry the
griffes or claws, and the rollers'o; are both connected to arod E, which is caused
to rise and fall by a crank on the axis of the pulley. Li..
'
Figure 3 shews á card cylinder carrying two sets of cards, these cards may
either be pierced for the same or for different designs. Sometimes if the.card
cylinder is moved by the workman in jerks the cards are caused to jump,and
thus they sometimes iget out of gear with the pins projecting from the sides of
the cylinder. Now in order to prevent the cards thus getting out of gear with
the cylinder, I embrace the upper half of each end of the cylinder with the
arc of a'circle;between which and the cylinder there is sufficient space to allow
the cylinder to rotate freely,but there is not sufficient space to allow the cards
to get off the pins adom door
tota
Figure 4 shews'a section of a card cylinder, and also aniarcq;.thus-applied
to it, one such are being near each end of the cylinder; the arcs a are carried
from the cross piece Tas shown? The
It sometimes happens that the jacquard cylinder of looms is either not suffi-
ciently rotated by the workmantorrelse is rotated too far, so that the cylinder
does not présent a flat face to the needles and imperfect work is thus produced.
Now in order to prevent the card fcylinder, acting on the needles, unless it is
properly rotated I-placed stop on the framing, against which if the cylinder is
not properly rotated one of the pins which project from the end of the cylinder,
and by which the cylinder is rotated as above described,icomes in contact and
-o.prevents the needles being acted on but when the cylinder is properly

page_text: rotated the pin on the cylinder is received into a slot-in the stop so that the
cylinder may move up to and act on the needles.
Figure 5 shews a stop thus applied. is the stop carried by the framing
.B, in this stop there is a slotu', into which if the cylinder a is properly rotated
one of the pins i, i¹, enters, and the cylinder is thus free to move up to the
needles; but if the cylinder is improperly rotated, as shewn at Figure 5,one of
the pins will strike against the stop; and the cylinder will then be prevented
from acting on the needles.
In place of connecting together jacquard cards in the ordinary, manner I
connect them together by strips of metal hent to an oval form, thus the
strips of metal being first passed through sinall slots near the sides of the cards
and then bent over as shewn above.
Figure 1, (Sheet 2), shews cards connected together in this manner; nn,
being the metallic connections, and e, e, the holes in the cards through which
they are passed.
In the Specification of the Patent above referred to,a machine was described
Ifor punching the holes in the jacquard cards, which consisted of a number of
punches set together in a frame, there' being a separate punch for every hole
that might have to be formed in the cards, and each punch was furnished with
a spring by which it was constantly pressed upwards. The card to be punched
was supported on a barrel or cylinder below the punches, and when
punching the holes in the cards the punches corresponding to the holes
to be made were each knocked down separately by a blow and so caused
to pierce the card.
Now according to this Invention I place above the tops of a number of
punches,arrangedas above described, a plate having formed through it a number
of holes corresponding to the tops of the punches,so that when the heads ofthe
punches are opposite the holes in the plate, the plate may be depressed without
depressing any of the punches, but when the heads of any of the punches are
moved so as not to be opposite their corresponding holes in the plate, when
-the plate is caused to descend those punches that have been moved will be
pressed down likewise, and caused to pierce the card. In order to be able to
move any of the punches, each punch near its upper end is attached by a rod
to one arm of a bell-crank lever, the bell-crank levers are arranged side
by side on a fixed rod around which they are capable of turning, and between
each of the levers there is a spring so that any of the lavers may be moved
without moving the levers on either side of it; the other arms of the bell crank
levers form keys, and by depressing any of the keys, and so turning the bell

page_text: crank on its centre, the punch to which the crank is connected will be noved,
so that its head will not be opposite its hole in the plate. The pattern to which
the cards are to be punched, and which is usually drawn on paper,divided into
a number of small squares, some of which are colored and the others plain,is
supported on a table just below the arms of the bell crank levers, which act
as keys; the squares on the pattern are of the same width as the key, so that
there is a square of the pattern just opposite each key.
In order to arrange the punches so as to punch holes in a card to corres-
pond with the pattern, the workman depresses those keys which are opposite
either the colored or uncolored squares of the pattern; the plate above the
punches is then depressed, and those punches that have been moved will be
caused to pierce the card below them, the punches are then moved back to the
original position, the pattern surface is by means of clips moved forward, so as
to bring a fresh row of squares in front of the keys, and the chain of blank
cards is also moved forward, so as to bring a fresh card under the punches,
when the same operation is repeated. In order to bring back the punch-s
after they have been moved to their original position, I place above the ends
of the arms of the bell-crank levers to which the punches are connected, and
parallel with the axis on which the levers turn, a roller having projecting from
ita tooth, which extends the whole length of the roller, and when it is required
to bring the punches to their original position the roller is caused to turn, so
as to bring the tooth upon it against the ends of the arms of the bell-crank
levers, and move them all to their original positions. The plate above the
punches may be depressed by an excentric or cam, on an axis above the plate,
or by a screw or otherwise.

Figure 2 is a side view, and Figure 3 a front view, both partly in section,
of an apparatus constructed as above described; Figure 4 is a-front view,
and Figure 5 a plan of the same. B, B, is a framing, on one side of which
are a number of punches e, e, suitable for opening holes in the cards, and on
the other side a rectangular box enclosing a number of bell-crank levers à, a',
mounted on a common axis. The framing is tied together by two cross bars
m, m, and m³, m³, the cross bar m², m', being slotted in the middle for the
passage of the punches. Above the heads of the punches is a cover A, A,
which covers the heads of the punches,and can both raise and dépress them.
The under side of the cover is furnished with a plate inwhich there are oblong
holes u, u, which permit the heads of the punches to move freely from left to
right, or vice versâ; but the heads of the punches are made with enlarge-
ments just above the holes in the plate, so that when the plate is raised the

page_text: punches will be raised at the same time. Through the top of the cover A are
also a number of holes which correspond with the heads of the punches when
they are in their normal position; connected to the cover A are two rods
which work through holes in the cross bars m, m², and thus ensure that the
cover shall move up and down correctly. The cover A has also two other
rods D', D', connected to it; the ends of these rods. when the cover is
depressed, enter the holes in the cards, into which the pins on the card
cylinder enter, and thus ensure the punches passing correctly through the
holes in the card. The cover A is moved up and down by means of the lever
L on the axis c; this axis turns excentrically on the smaller parts o of the
axis, which work through holes in the standards P, P, carried by the trans-
verse bar m³, and on the axis care rollers G, which when the axis is turned
by the lever L, press down the cover A. The standards P, P, pass through
slots in the cover A. On the axis c are two cams v, v, embraced by a sliding
piece q, q; when the lever L is depressed the cams move the sliding pieces,
and these pieces give motion to a lever h, which has hinged to its lower end a
rod N this rod has a projection on its under side, which, when the rod is
forced forwards, comes against one of the pins e*, e*, on one of the hexagonal
cylinders which support the cards to be pierced, and causes the cylinder to
make a partial rotation. Each of the punches e, e, has connected to it a
piece n³, which is connected to the arm a of one of the bell-crank levers a, a¹;
by another connecting rod n the pieces n' are kept in their proper position by
passing through holes in a plate D, as shown at Figures 2 and 3. The ends
of the arm a of the levers a, a', project beyond the front of the rectangular
box which encloses the levers, and form a row of keys. Between the bell-
cranks a, a, are springs E (see Figure 2) in order to isolate each bell-crauk
from the cranks on either side of it, so that any of the cranks may be moved
without its neighbouring ones being moved at the same time. Below the
rectangular box containing the levers is a table for supporting the pattern to
which the cards are to be punched; this pattern is, as before stated, divided
into squares corresponding in size to the distance between the centres of the
keys a. The edges of the pattern are held by two clips c, c, (see Figure 5)
carried by a slide u, u, sliding in a groove u, u¹. R is a rod of iron con-
nected at one end by a collar to the projection p',and having at its other end
a screw thread screwing through a lever / connected with the slidė u; by
turning the rod R in one or other direction, the pattern may be moved to
the left or to the right. The action is as follows:-When the pattern has
been adjusted so that the squares are opposite to the keys a, those keys which

page_text: are opposite either the colored or uncolored squares are depressed by means
of the tool shewn at Figures 6. This tool is made-thin in order to be able to
depress one key without depressing the neighbouring-keys; the depressing the
keys moves, as above explained, the heads of the respective punches e, e, to..
which they are attached, so that their heads are not opposite holes in the cover
A. The axis c is then turned by moving the lever L from left to right, by
which the cover A is depressed, and those punches which have been moved by
the keys will be depressed with it, and caused to pierce the card below them,
whilst the others will remain stationary. The movement of the lever L to
depress the cover A also depresses the lever h, and thus draws back the rod.
N, and when the lever. L is moved so as to raise the punches, the rod N is
moved forwards by the lever h, and the pin on the under side of the rod N
acts on one of the pins e* and revolves the card cylinder, thus moving the
chain of cards forward, and bringing a fresh card under the punches. The
bell-crank levers a, a, are then all moved back to their original position by
means of a tooth d on the roller c; this roller is carried by the standards/*
from the box which encloses the levers a, a¹. On the roller cx is a lever F
by which the roller c* may be turned on its axis, and the tooth d on the-roller
brought against the ends of the arms a of the levers a, a¹, by which means all:
the levers, and consequently all the punchos to which they are attached, will
be moved back to their original position.
In some cases, in a set of cards, a number of cards are required to be of the
same pattern, and when such is the case, in order to save the time required.
for depressing each of the keys separately, as above described, Iarrange along
the roller above the bell-crank levers a number of moveable projections or
teeth, there being one such tooth for every bell-crank lever; each of these
teeth can either be caused to project from the roller, so as when the roller is
turned on its axis to come in contact with the bell-crank levers, and so move
the punches, or may be turned down flat on to the roller so as not to come in
contact with the bell-cranks. By this means, by causing only those teeth
which are required to act on the bell-cranks to project from the roller by
merely causing the roller to turn on its axis, the punches will be suitably
arranged for piercing the card, and by turning the roller back again in the
opposite direction, the fixed tooth on the roller will be caused to act on the
levers, and bring them to their original position, as above described.
Figure 2 shews teeth d' of this description applied to the roller c.* When.
any of the teeth d¹ are turned into the position shewn by dotted lines, these
teeth will not act on the levers a, a¹, below them, but the teeth which have.

not been so moved will, when the roller c* is turned by the handle F, come
against the ends of the arms a of the levers, and move them in the
manner as when the arms a¹ of the levers are depressed. Fig. 8 shews the
machine arranged in such manuer that the cover A is moved by means of
a screw.

In order, when one set of.cards has been punched according to the pattern
to be produced, to be able to make several sets of cards to correspond with it,
I arrange a machine in the following manner: The set of cards which is to
be copied is supported on a cylinder similar to the jacquard cylinder of, a
loon, and this cylinder is moved to and from a set of needles similar to the
jacquard needles. Each of these needles is connected to one of a set of
punches, arranged in a similar manner to that just described, except that the
heads of the punches, in place of being opposite the holes in the plate, are in
such a position that they would all be depressed by the plate if they were not
moved before the plate descended. When the card cylinder comes up to the
needles, those needles which are oppo-ite the hole in the card presented to
them will not be acted on,but the. other needles will be pressed back by the
card, and this movement will, bring the heads of the punches to which they
are connected opposite their holes in the plate, so that when the plate
descends, those punches that have been moved will not be acted on, but the
other punches will be depressed, and caused to pierce one of a set of cards
below them. The cylinder each time that it recedes from, the needles is
caused partially to rotate, so as when it again approaches the needles to
present a fresh card to them, and before the punches are again depressed, the
set of cards beneath them is moved forward so as to bring a fresh blank card
under the punches.
Figure 7 shews a machine of the above description. P is a lever carrying
a card cylinder upon which the set of cards to be reproduced is carried; this
lever turns at its lower end on.au axis carried by the framing B. The card
cylinder is opposite to a set of needles e, e; each of these needles is connected
at its rear end to pieces n, n, each of which is connected. with one. of the
punches, which punches are arranged in a similar manner to the punches in
the machine above described. The pieces n, n, are kept in their proper
position by passing through holes in the plates c, c¹; the plate. 'T' is similar to
the one shewn at Figure 1, Sheet 1,.aud works in the same manner. The
action of the machine is as follows:-The set of cards to be copied is placed
on the cylinder carried by the.lever P, and the set of cards to be pierced are
supported on hexagons m, m, similar to the ones in the machine above

page_text: described. If the lever L is then moved from left to right, the jacquard
cylinder is moved up to the needles by means of the connecting rod A; those
needles which are opposite open holes in the card remain stationary, but the
others are pushed back by the card to such an extent as to bring the heads of
the punches with which they are connected opposite to their holes in the plate.
By the further movement of the lever the cover A is depressed, and the
punches which have not been moved from their original position are depressed
by it, and caused to pierce the card below them. When the cover A is raised
by the movement of the lever, the card cylinder carried by the lever P is
rotated so as to present a fresh card to the needles, and the cylinders m carry-
ing the set of cards to be punched are also rotated so as to bring a fresh card
under the punches. When the cover A is again depressed, the same action
is repeated.
In witness whereof, I, the said Jacques Rives, have hereunto set my
hand and seal, this Twenty-sixth day of January, in the year of our
Lord One thousand eight hundred and sixty-one.
