COMPLETE SPECIFICATION.
Improved Jacquard-card Stamping Machine.
I, ALFRED PIEDFORT, Clergyman, Professor of Science, of Calais (Pas de Calais),
in the Republic of France, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:
This invention for an improved Jacquard-card stamping machine relates to
the combination with the ordinary parts, viz., the carriage for moving the cards,
punches, keys, and other mechanism employed in stamping Jacquard-cards by
hand, of a mechanical contrivance which enables the punches to be set in action
and to be suddenly stopped, as also the cards themselves, the action being carried
on by the assistance of a motor.
The improved stamping machine is illustrated in the accompanying drawing,
in which
Fig. 1 is a detached view showing the parts of the mechanism in plan arranged
on a raised table.
Fig. 2 is a longitudinal side elevation of the machine.
Fig. 3 is a longitudinal vertical section.
Fig. 4 is an end elevation.
Fig. 5 is a transverse vertical section and Fig. G is a view, on a large scale,
of the crenelated plates.
A table A, made of cast-iron is fixed by means of bolts to the four legs of an
ordinary frame which supports the carriage g, the table supporting two shafts B B¹
which rotate in the bearing blocks F. On the shaft B are mounted an idle
pulley D and a driving pulley E, over which runs the belt C (Figs. 1 and 5)
which, when the machine is stopped can be slid on to the pulley D by means of
the shifting lever S. On the shaft 13 is mounted a tooth wheel G. which engages
with a larger wheel H fixed on the shaft 331. At one end of the shaft B is a fly-
wheel L and near to the wheel L is a pulley K over which runs a belt N whereby
motion is imparted to the mechanism for bringing back the carriage g.
is fixed to the shaft B¹ (Figs. 1 and 3).
A cam I
A lever O pivoted to the frame at (Fig. 3) and provided with a spring
attached to the table A by the piece M, is furnished with a roller J which runs
over the cam I. This lever O is linked at its extremity to a connecting rod j
fixed to a depending piece q on the upper crenelated plate P¹.
Two crenelated plates P P are furnished with grooves (Figs. 3 and 6) and
arranged in such a manner that the solid parts of the one can fit exactly into the
spaces formed in the other. The lower plate P is fixed to the piece W and can
be caused to slide forwards to the extent of the width of an indentation, when
the workman presses the pedal n, this being due to the movement of a bent
lever qoz connected to the rod m of the pedal. The plate P cannot more down-
wards without actuating the punch head c to which it is fixed by the columns Y

page_text: which pass through the upper plate P¹. The piece W is pulled upwards by two
springs XX (Figs. 2 and 4). The upward movement of the plate P¹ each time
the lever O is lowered, is effected through the connecting rod j.
A lever U (Fig. 2) actuated by means of the piece W and acting on the con-
necting rod T causes the carriage to move forwards with each movement of the
piece Win the usual manner.
A chain with a free end is fixed at to the carriage g which moves the
cards. This chain runs over pulleys på p and round a rotary drum h which con-
stantly rotates under the action of the belt N and the gearing R and Q (Figs. 2
and 5).
The action of the machine is as follows:-
-
On the driving belt C being pushed over the pulley E, the shaft B, its fly-
wheel L and other parts rotate, the shaft B' then causes the cam I to rotate, which
at each rotation, raises the lever 0, and only lowers the plate P₁ which is raised
immediately after the passage of the cam I, under the action of the spring 7. If
the workman is not ready to stamp, he does not press the pedal n and thus the
plate in descending, comes down in such a manner that the solid parts of the
same engage in the spaces formed in the plate P, so that the lower plate is not
carried along and the head c remains in its place; as a consequence, the piece W
does not act, the lever U remains still and the card to be stamped does not move
forwards.
As soon as the workman wishes to stamp a card, he presses the pedal n, thus
displacing the lever qoz which pushes the plate P to the extent of half a centi-
metre, so that the solid parts of the plate P come opposite to those of the plate P¹,
which then in descending carries along the piece W and causes the punches_r
to be lowered at the same time bringing forward the card by means of the lever U.
The punches descend and effect stamping at each rotation of the cam I and as
long as the workman keeps his foot on the pedal n. As soon as any difficulty
occurs in reading, he raises his foot, the plate P returns to its first position and
the head ceases to descend. The rod m is attached to the lever go through the
medium of a spring intended to prevent the workman from damaging the
plates P P by improper working.
When the stamping of the card is completed, the carriage, in consequence of
the effect of the weight t, has reached the end of its course. In order to bring it
forward again, the workman pulls the free part of the chain i, so that the rotary
drum rotating constantly in the direction of the arrow brings back the
carriage. When the carriage is in position, the workman lets go the chain ¿¹
which remains loose.
The letters a b c d e f g refer to known parts employed in ordinary stamping
machines worked by hand.
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. Jacquard-card stamping machine actuated by a motor, consisting in the com-
bination, with the ordinary parts, viz., the carriage for moving the cards, punches,
keys, and other mechanism employed in stamping machines worked by hand, of
an arrangement of superposed double crenelated plates P P the upper plate of
which is moved downwards by means of a lever O which is raised by a cam I
actuated by the driving shaft, and one of which plates P can be displaced later-
ally by a pedal n, through the medium of a bent lever goz: the said crenelated
plates thus raising the punches and displacing the carriage, which moves the cards,
by means of a piece W attached to the lower plate P, only when the work man
presses the pedal n. with the object of setting the working parts in action instan-
taneously and suddenly stopping them without inconvenience to the workman.
2. In a Jacquard-card stamping machine, worked by motor, mechanism for
returning the carriage for moving the cards to its original position, consisting

page_text: in causing the traction chain i to run over a rotary drum h which is constantly
in rotation and in pulling the free part of the said chain, in order to cause the
drum to draw the carriage along.
