Electrically Controlled Design Reading Apparatus for Punching
Jacquard and like Cards.
I, BENJAMIN JOSEPH BARNARD MILLS, of 23, Southampton Buildings, in the
County of London, Patent Agent, do hereby declare the nature of this invention
(a communication to me from Lucien David and Tony David, both of 32, Rue des
Tables Claudiennes, Lyons, in the Republic of France, Design Readers)
to be as follows:-
The process of design reading forming the subject of the present invention is
effected by means of electricity, it is characterised by the special arrangement
of the card intended to produce the electric operations acting upon the machine,
which arrangement enables to be read successively and separately upon this single
card, all the colors and various armures or mountings contained in a design
which has not hitherto been capable of realization.
To construct this card, a sheet of tin foil is cemented upon a sheet of strong
paper, or upon other suitable foundation being a non-conductor of electricity.
On this sheet of tin foil is drawn on an enlarged scale a reproduction of the
design and on this design are drawn the contours of the parts or zones which com-
prise different colors or armures or mountings.
The tin, between the different zones thus drawn, is then removed, and metallic
surfaces insulated from each other are thus obtained.
As far as the design will permit it is so arranged that the zones of like nature
are not interrupted, if this condition cannot be fulfilled, the portions of zone of
like nature are electrically connected by conductors passing beneath the card
and carefully insulated.
The accompanying drawing represents diagrammatically a card A thus con-
structed, in which the different zones are indicated by Z1, Z2, Z3, Z, these zones
are supposed to be formed of continuous surfaces, in order to facilitate the
description.
This card is fixed upon a carriage B, moving in a direction parallel to that of
the chain by means of a screw C, operated by a ratchet gear C₁ which causes the
carriage to advance each time a quantity corresponding to a shoot of the weft.
Above the card A and in the direction of the weft is fixed a comb F, the
metallic teeth of which are perfectly insulated from each other and occupy the
position corresponding to the threads of the warp.
The teeth of the comb F, are connected respectively by the conductors G, to
a series of electro-magnets E, E, acting in the manner hereinafter explained, on
the Jacquard needles J, which govern the punching of the cards. All the electro-
magnets E are also in communication, by the same conductor H, with one pole
of the battery P. The other pole of this battery communicates with a com-
mutator D, which by means of contacts I, I, I, I, sends the current at will to
one or other of the zones Z¹ 72 73 74 of the card.
Thus it will be understood that the comb F occupying the position of a shoot
of weft and the commutator D being turned to the contact I', the current will

page_text: pass only through the teeth of the comb which rest on the zone Z¹ of the design,
and through the corresponding electro magnets. If the commutator D is caused
to turn to the contact 12 the current will pass only through the teeth of the comb
resting on the zone Z2 and through the corresponding electro magnets, and so on.
Thus for each shoot of weft the needles of the Jacquard corresponding with
the different colors or armures or mountings can be successively and separately
operated.
The Jacquard J governs by known means, the punches of the card punching
machine, the needles K of this Jacquard could be directly operated by the
electro magnets E, but to reduce the electric work, it is preferred to employ an
intermediary apparatus placed in front of the Jacquard and composed of a set
of needles L, corresponding with the needles K and connected separately to as
many small very light pendulums M, the lower parts of which serve as armatures
to the electro magnets E.
When at rest the pendulums M, rest by a bent part, upon the bars of a
horizontal grille or griff N, which receives at the desired time an upward motion
by means of a cam O.
Those of the pendulums M which are attracted by their electro magnets,
escape the grille or griff and with their needles L remain in position. A vertical
grille or griff R, the spaces of which are in front of the needles L, when at rest,
pushes back all those needles which have been raised, as also the corresponding
needles of the Jacquard J.
It results from this arrangement, that the electro magnels traversed by the
current, attract their pendulums M and subject them to the action of the grille
or griff N. the corresponding needles L and K remain in position and the corre-
sponding hooks of the Jacquard J are raised by the griff S, and determine the
punching of corresponding holes in the card being punched. The non active
electro magnets on the contrary leave their pendulums M in position, these are
raised by the grille or griff N, as also their needles which are pushed back by
the grille or griff R. The corresponding hooks of the Jacquard J, therefore
escape the action of the griff S, and no hole is punched in the card.
.
In recapitulation, each movement of the Jacquard will determine the punching
of holes corresponding with the teeth of the comb F, which at such moment
are in contact with the zone traversed by the current and by the operation of the
commutator D, the holes corresponding with each of the zones composing the
design can be separately and successively punched.
Any known means can be employed to transmit to the Jacquard needles J,
the movements determined by the magnetization of the electro magnets E, the
means above described being mentioned only as an example.

Electrically Controlled Design Reading Apparatus for Punching
Jacquard and like Cards.
I, BENJAMIN JOSEPH BARNARD MILLS, of 23, Southampton Buildings, in the
County of London, Patent Agent, do hereby declare the nature of this invention,
(a communication to me from Lucien David and Tony David, both of 32, Rue des
Tables Claudiennes, Lyons, in the Republic of France, Design Readers),

page_text: and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement ;-
1
The process of design reading forming the subject of the present invention is
effected by means of electricity, it is characterized by the special arrangement
of the card intended to produce the electric operations acting upon the machine,
which arrangement enables all the colors and various armures or mountings
contained in a design to be read successively and separately upon this single
card which has not hitherto been capable of realization.
To construct this card, a sheet of tin foil is cemented upon a sheet of strong
paper, or upon other suitable foundation being a non-conductor of electricity.
On this sheet of tin-foil is' drawn on an enlarged scale a reproduction of the
design, and on this design are drawn the contours of the parts or zones which
comprise different colors or armures or mountings.
The tin foil between the different zones thus drawn, is then removed, and
metallic surfaces insulated from each other are thus obtained.
As far as the design will permit it is so arranged that the zones of like nature
are not interrupted, if this condition cannot be fulfilled, the portions of zone of
like nature are electrically connected by conductors passing beneath the card
and carefully insulated.
The drawing accompanying my Provisional Specification represents diagram-
matically a card A. thus constructed, in which the different zones are indicated
by 71, 72, 73, 74, these zones are supposed to be formed of continuous surfaces, in
order to facilitate the description.
This card is fixed upon a carriage B, moving in a direction parallel to that of
the chain by means of a screw C, operated by a ratchet gear which causes the
carriage to advance each time a quantity corresponding to a shoot of the weft.
Above the card A and in the direction of the weft is fixed a comb F, the
metallic teeth of which are perfectly insulated from each other and occupy the
position corresponding to the threads of the warp.
The teeth of the comb F are connected respectively by the conductors G, to
a series of electro magnets E, E, acting in the manner hereinafter explained, on
the Jacquard needles J, which govern the punching of the cards. All the electro-
magnets E are also in communication, by the same conductor H, with one pole
of the battery P. The other pole of this battery communicates with a com-
mutator 1), which by means of contacts I, I, I, I, sends the current at will to
one or other of the zones 7 7 7 7 of the card.
Thus it will be understood that the comb F occupying the position of a shoot
of weft and the commutator D being turned to the contact I, the current will
pass only through the teeth of the comb which rest on the zone of the design,
and through the corresponding electro magnets. If the commutator I) is caused
to turn to the contact I2 the current will pass only through the teeth of the comb
resting on the zone 72 and through the corresponding electro magnets, and so on.
Thus for each shoot of weft the needles of the Jacquard corresponding with
the different colors or armures or mountings of such shoot can be successively
and separately operated.
The Jacquard J governs by known means, the punches of the card punching
machine, the needles K of this Jacquard could be directly operated by the
electro magnets E, but to reduce the electric work, it is preferred to employ an
intermediary apparatus placed in front of the Jacquard and composed of a set
of needles L, corresponding with the needles K and connected separately to as
many small very light pendulums M, the lower parts of which serve as armatures
to the electro magnets E.
When at rest the pendulums M, rest by a bent part, upon the bars of a
horizontal grille or griff N, which receives at the desired time an upward motion
by means of a cam O.
Those of the pendulums M which are attracted by their electro magnets.
escape the grille or griff and with their needles L remain in position. A vertical

page_text: grille or griff R, the spaces of which are in front of the needles L, when at rest,
pushes back all those needles which have been raised, as also the corresponding
needles of the Jacquard J.
It results from this arrangement, that the electro magnets traversed by the
current, attract their pendulums M and subject them to the action of the grille
or griff N, the corresponding needles L and K remain in position and the corre-
sponding hooks of the Jacquard J are raised by the griff S, and determine the
punching of corresponding holes in the card being punched. The non active
electro magnets on the contrary leave their pendulums M in position, these are
raised by the grille or griff N, as also their needles which are then pushed back by
the grille or griff R. The corresponding hooks of the Jacquard J, therefore
escape the action of the griff S, and no hole is punched in the card.
In recapitulation, each movement of the Jacquard will determine the punching
of holes corresponding with the teeth of the comb F, which at such moment
are in contact with the zone traversed by the current and by the operation of the
commutator D, the holes corresponding with each of the zones composing the
design can be separately and successively punched.
Any known mechanical means can be employed to transmit to the Jacquard
needles, J, the movements determined by the energizing of the electro mag-
nets E, the means above described being mentioned only as an example.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
1. An electrically controlled design reading apparatus for punching Jacquard
and like cards constructed, substantially as herein set forth and illustrated in
the drawings.
2. In an electrically controlled design reading apparatus for punching Jacquard
and like cards the combination of a card on which the design is reproduced on
a metallic sheet divided into continuous or non-continuous zones, insulated from
each other and comprising the colors or armures or mountings of like nature, -a
comb the metallic teeth of which, insulated from each other, represent the warp
threads and which by the moving of the design is caused to occupy successively
the positions on the latter corresponding with successive shoots of weft, the
teeth of the comb being connected to an equal number of electro magnets acting
upon the Jacquard of the punching apparatus, and a commutator which allows
the current to pass at each action only into the zone of the card comprising the
color or armure or mounting which it is required to read, substantially as herein
set forth.
