PIERRE AMBJORN COMTE DE SPARRE of Boulevard Saint Denis 1 at Paris,
Engineer "IMPROVED MACHINERY OR APPARATUS FOR PRICKING OR PIERCING
CARDS FOR JACQUARD LOOMS WITH MECHANICAL APPLIANCES FOR CONTROLLING
THE WORK"
My invention relates to machinery or apparatus for piercing cards for jacguard
looms and mechanism for controlling the work. The apparatus is based on the
employment of an engraved plate representing exactly in intaglio and in relief
the design to be produced by weaving by means of the cards to be pierced, the
said plate acting on a row of oscillating keys which transmit their movements to
small wires with square heels; these hooks according to whether they are or are
not acted upon by the keys act or do not act on the bars or pushers of the
horizontal rods which actuate directly the large vertical wires or hooks of the
punches of an ordinary jacguard card punching machine. By this arrangement
the reliefs or raised parts of the design of the engraved plate alone act on the
punches for piercing the card under operation while the hollows of the same design
have no effect on the punches which in this way are not moved in the piercing
machine and therefore do not pierce the card. The inverse action can also be
produced without altering the result.
In combination with this mechanism for piercing the cards I employ an arrange.
ment or mechanism for controlling the work which transfers or reproduces by

page_text: impressing (with black ink or color with or without a paper medium bearing the
color) upon a sheet of paper the design point for point corresponding exactly with
the piercing of the cards. This printing point for point thus reproduces the
original design of the engraved plate and constitutes a marking which allows of
continuously checking the progress of the piercing and of rectifying it in case
of error.
The engraved plate is fixed vertically on a sliding carriage which can be raised
and lowered for preparatory operations by means of cranked handles and toothed
pinions acting on corresponding racks fixed behind the carriage. For this move-
ment effected by hand it is necessary that the nut hereinafter referred to should be
freed that is to say disengaged from a vertical screw which serves as the regular
mechanical power for the progressive advance of the carriage during the work of
the machine. For this purpose the nut is formed of two parts hinged together
and which are only in gear with the screw when they are brought together and
tightened by a spring key. The plate carriage is also capable of moving horizontally
under the action of a horizontal slide which is itself put in motion by a roller
bearing or trunnion displaced horizontally by a curved groove acting as a cam in
a vertical slide which may be called a piston. This slide or piston as well as the
horizontal slide are repeated at each side of the machine so that the plate carriage
may be actuated symmetrically. Screws with actuating pinions worked by a crank
handle and screws serve to regulate the position of the carriage. Each horizontal
movement of the carriage causes by means of pauls the vertical screw before
described to turn so that after every displacement of the carriage with the plate
the plate has descended or risen according to the direction of the rotation of the
said screw of which one is absolutely the master.
Therefore the movement of the plate can be analyzed thus-A stroke of the
plate horizontally forward to actuate along a single horizontal line the transmitting
devices for the punching machine; then a return or backward stroke which at the
same time causes the-plate to rise or descend in such manner that at its next
forward stroke the next line will actuate the transmitting devices and so on until
all the points of the plate by successive horizontal lines have in their turn actuated
the transmitting devices. The pauls are actuated by levers which oscillate at each
horizontal movement of the carriage; these levers are fitted at their ends with
toothed sectors which gear with other toothed sectors fixed to the paul carriers.
The devices which transfer or transmit the successive hollows and reliefs of the
engraved plate into movements of the punches of an ordinary card piercing
machine are arranged as follows: -Opposite the engraved plate are pivoted keys
composed of thin steel. The nose of these keys is the part which is in direct
contact with the engraved plate. Where there is a relief or raised part on the
plate the nose is pushed, the key oscillates, its tail or opposite end rises and lifts
the small wires with square heels. These in rising become placed with their heels
in gear with the horizontal bars or pushers which are therefore pushed and which
in their turn push the long horizontal rods into a ring from which are passed the
large double vertical wires or looks which directly work the cords of the punches
of an ordinary card piercing machine. According to whether these wires are left
at rest or are pushed by the mechanism just described they are or are not taken
by the transverse blades of the ordinary piercing machine. It will therefore be
understood that the hollows and reliefs of the engraved plate are transferred into
inaction or action of the punches of the-piercing machine.
To the lower parts of the cords which come from the large vertical wires or
hooks above mentioned are connected corresponding oblique cords which pass
through combs and terminate at the tail of a corresponding number of claws.
These claws are of thin steel. They are pivoted and are drawn in one direction
by the pull of the cords and in the other direction by coiled springs which for
convenience are arranged like a fan. The lower part of the claws is curved
concentrically with the pivot and is fitted with a stile for producing an impression
on a fixed sheet of paper when. the parts are lowered, this lowering movement

engraved plate. When the stile is down in the vertical position it imprints a mark
on the paper with or without direct inking or by the intermediation of paper
impregnated with ink. This position corresponds with the pull of the cords that
is to say to the relief of the engraved plate and to the piercing of a hole in the
jacguard card under treatment. When on the contrary the stile is drawn up by
the automatic action of the springs it does not make a mark on the paper and this
corresponds to the non-motion of the corresponding cords, to an unpierced part of
the card and to a hollow of the engraved plate. The paper is placed horizontally
on a carriage to which is fixed a nut having an endless screw which receives an
intermittent advance rotary motion after each impressing motion of the stiles. The
vertical movement of the frame which carries the stiles is produced by means of
levers actuated by pins on the sides of the lower carriage of the card piercing
machine. The advance movement of the screw which actuates intermittently the
carriage on which the paper is placed is produced by levers which actuate pauls
these pauls imparting rotation to a ratchet wheel keyed on the end of the screw

PIERRE AMBJORN COMTE. DE SPARRE of Boulevard Saint Denis 1 at Paris
Engineer "IMPROVED MACHINERY OR APPARATUS FOR PRICKING OR PIERCING
CARDS FOR JACQUARD LOOMS WITH MECHANICAL APPLIANCES FOR CONTROLLING
THE WORK
"
My invention relates to machinery or apparatus for piercing cards for jacquard
looms and mechanism for controlling the work. The apparatus is based on the
employment of an engraved plate representing exactly in intaglio and in relief the
design to be produced by weaving by means of the cards to be pierced, the said
plate acting on a row of oscillating keys which transmit their movements to small
wires with square heels; these hooks according to whether they are or are not
acted upon by the keys act or do not act on the bars or pushers of the horizontal
rods which actuate directly the large vertical wires or hooks of the punches of an
ordinary jacquard card punching machine. By this arrangement the reliefs or
raised parts of the design of the engraved plate alone act on the punches for
piercing the card under operation while the hollows of the same design have no
effect on the punches which in this way are not moved in the piercing machine
and therefore do not pierce the card. The inverse action can also be produced
without altering the result.
"
In combination with this mechanism for piercing the cards I employ an arrange-
ment or mechanism for controlling the work which transfers or reproduces by
impressing (with black ink or colour with or without a paper medium bearing the
colour) upon a sheet of paper the design point for point corresponding exactly with
the piercing of the cards. This printing point for point thus reproduces the
original design of the engraved plate and constitutes a marking which allows of
continuously checking the progress of the piercing and of rectifying it in case
of error.
The annexed drawings illustrate the invention, Figure 1 is a side view of the
mechanism which causes the movement of the punches of the ordinary jacquard
card punching machine in correspondence with the hollows and reliefs of the
engraved plate according to the design to be produced. Figure 2 is a front view
and Figure 3 a plan of the same. Figures 4 and 5 are detail views and Figure 6
is a diagram showing the respective positions of the different parts of the
mechanism for operating the punches.
The engraved plate P Figure 1 is fixed vertically on a sliding carriage A which
can be raised and lowered for preparatory operations by means of cranked
handles mm and toothed pinions m'm' acting on corresponding racks fixed behind
the carriage. For this movement effected by hand it is necessary that the nut E
which is shown separately in Figures 4 and 5 should be freed, that is to say
disengaged from a vertical screw V which serves as the regular mechanical power
for the progressive advance of the carriage during the work of the machine. For
this purpose the nut E Figures 4 and 5 is formed of two parts hinged together
and which are only in gear with the screw when they are brought together and
tightened by a spring key E. The plate carriage A is also capable of moving
horizontally under the action of a horizontal slide G which is itself put in motion
by a roller bearing or trunion t displaced horizontally by a curved groove R acting
as a cam in a vertical slide C which may be called a piston. This slide or piston
as well as the horizontal slide are repeated at each side of the machine so that the

page_text: plate carriage A may be actuated symmetrically. Screws with actuating
pinions z worked by a crank handle w and screws w₁ w serve to regulate the
position of the carriage A. Each horizontal movement of the carriage A causes
by means of pauls cc Figures 2 and 3 the vertical screw V to turn so that
after every displacement of the carriage with the plate, the plate has descended
or risen according to the direction of the rotation of the said screw V of which
one is absolutely the master. Therefore the movement of the plate can be analyzed
thus A stroke of the plate horizontally forward to actuate along a single
horizontal line the transmitting devices for the punching machine; then a return
or backward stroke which at the same time causes the plate to rise or descend
in such manner that at its next forward stroke the next line will actuate the
transmitting devices and so on until all the points of the plate by successive
horizontal lines have in their turn actuated the transmitting devices. The
pauls c c are actuated by levers c¹ c¹ which oscillate at each horizontal movement
of the carriage; these levers are fitted at their ends with toothed sectors c² which
gear with other toothed sectors c³ fixed to the paul carriers c*. The devices
which transfer or transmit the successive hollows and reliefs of the engraved
plate into movements of the punches of an ordinary card piercing machine are
represented in detail in combination with each other in the diagramn Figure 6.
Figure 1 shows their position in relation to the machine. Opposite the engraved
plate P are keys a composed of thin steel and pivoted at a¹. The nose a of
these keys is the part which is in direct contact with the engraved plate.
Where there is a relief or raised part on the plate the nose a is pushed, the
key a oscillates, its tail or opposite end a³ rises and lifts the small wires b with
square heels b'. These in rising become placed with their heels b¹ in gear with
the horizontal bars or pushers & which are therefore pushed and which in there
turn push the long horizontal rods f into a ring f¹ from which are passed the
large double vertical wires or hooks g which directly work the cords of the punches
of an ordinary card piercing machine. According to whether these wires aro left
at rest or are pushed by the mechanism just described they are or are not taken
by the transverse blades of the ordinary piercing machine. It will therefore be
understood that the hollows and reliefs of the engraved plate are transferred into
inaction or action of the punches of the piercing machine.
Figure 7 is a sectional elevation, Figure 8 an end view, and Figure 9 a plan
of the part of the machine on which are arranged at the front M. the ordinary
jacquard card punching machine, and at the back the mechanism for controlling
the work of the machine. At xxx are the lower ends of the cords from the
vertical hooks g described with reference to Figures 1, 2 and 6. These cords act
as they do in ordinary machines but they can also be made to actuate the punches
which are attached thereto, either by drawing them up or pushing them as
thought preferable.
To the cords xxx are connected corresponding oblique cords y y y which pass
through combs h and terminate at the tail of a corresponding number of claws
one of which is shown separately in Figure 10. These claws are of thin steel.
They are pivoted at l'on a transverse bar i and are drawn in one direction by the
pull of the cords y y and in the other direction by coiled springs jj which are
arranged like a fan for convenience of placing them on supports kk. The lower
part of the claws is curved concentrically with the pivot and is fitted with a
stile 2 for producing an impression on a fixed sheet of paper when the parts are
lowered, this lowering movement corresponding exactly with each stroke of the
punches and each stroke of the engraved plate. When the stile 12 is down in
the vertical position it imprints a mark on the paper with or without direct inking
or by the intermediation of paper impregnated with ink. This position corresponds
with the pull of the cords y y that is to say to the relief of the engraved plate and
to the piercing of a hole in the jacquard card- under treatment. When on the
contrary the stile 2 is drawn up (as seen in dots in Figure 10) by the automatic
action of the springs ; ; it does not make a mark on the paper and this corresponds

page_text: to the non-motion of the corresponding cords y y to an unpierced part of the card
and to a hollow of the engraved plate. The paper is placed horizontally on a
carriage I to which is fixed a nut F having an endless screw W which receives an
intermittent advance rotary motion after each impressing motion of the stiles 1².
The vertical movement of the frame which carries the stiles is produced by means
of levers n n' n² actuated by pins o o on the sides of the lower carriage of the card
piercing machine. The advance movement of the screw W which actuates inter-
mittently the carriage I on which the paper is placed is produced by levers.p p'
which actuate pauls q q Figures 8 and 9 these pauls imparting rotation to a ratchet
wheel keyed on the end of the screw.
From the foregoing description it will be seen that this machine not only
'converts the hollows and reliefs of the engraved plate into a corresponding
punching or piercing of the Jacquard cards but also produces a controlling check
or impression upon the paper on the carriage I so that one can at any time see if
the machine is working without irregularites or failures
