Specification Accepted, 14th Oct., 1887.
I, EDUARDO PONT of Barcelona, in the Kingdom of Spain, Manufacturer, do hereby
declare the nature of this invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
This invention relates to Jacquard looms, in which patterned or design fabric is
woven and consists in certain improved construction or combination of devices for
operating the raising of the respective warp threads in the production of the design.
A further object of my invention is a construction to this end, which shall be
readily applicable to existing looms for the purpose of enabling designed or pattern
fabric to be produced thereon.
A further object of my invention is an improved pattern card.
The improved device consists essentially of a series of parallel needles arranged in
one or more rows or lines. The needles are straight and terminate each in a ring or
eye, from which is suspended the string forming the heddle for receiving the warp
thread in a similar manner as in Jacquard-or other looms. With the needles are
situated two bars or beams of a square cross section, one of which serves as guide and
support for the needles having a number of parallel perforations for the passage of
said needles. The other bar serves as support or guide for the cards and has two
movements viz. a reciprocating movement to and from the ends of the needles, and a
rotary movement about its axis so as to give it revolution on each travel; this bar
is provided along its length with grooves corresponding to the lines of holes in the
needle guide bar aforesaid.

page_text: The pattern cards are arranged to lie over each side of the cord guide-bar and are
of any suitable material having rows of perforations corresponding to the grooves of
the card guide bar. The cards may be perforated in the usual manner in corre
spondence to these needles which are not to be raised, or my improved cards may be
used; these have the same number of holos as there are perforations in the needle
guide bar, such holes in the cards being closed as hereinafter described, as
required to operate the raising of the respective warp threads. For this purpose
each hole of the card carries a removable disc or slip so affixed to the card that it
can be easily removed from or placed over the respective hole.
are
The movements of the needle-guide bar and of the card guide bar take place on
each stroke of the loom, the guide recedes until the points of the needles are hidden
in the perforations thereof and arrives against the card upon the card guide bar, thus
enclosing the card securely and accurately as to the perfect correspondence of the
holes in the latter with the perforations in the needle guide bar. The bars then
advance and the ends of the needles arrive against the card, those needles being
raised which correspond to the closed holes in said card. When the card recedes, the
needles resume their original position by the action of poises suspended from the
needles.
If the design intended to be produced requires but four cards, the latter can be
arranged on the faces of the bar, but if the design necessitates more cards, they may
be arranged as an endless band.
The length of the needle guide bar and of the card bar is variable so as to allow
several series of cards to be arranged on the same bar, when the designs to be
produced in the fabric are so intricate as to require a large number of needles. The
same result may be attained by increasing the number of rows of needles and
consequently the number of holes in the bars, or even by increasing the breadth of
their faces.
By the application of this mechanism, the same designs as on a Jacquard loom are
produced on any loom, but with the following advantages:
1) The arrangement of the needles completely separated from each other yet visible
for the weaver and protected from damage in working.
2) The application of cards with removable plates or slips arranged so as to allow
each hole to be covered or uncovered, thus dispensing with a great number of series
of perforated cards, one for each design to be produced; for with a limited amount of
cards, in uncovering or covering the necessary holes, all desirable designs can be
produced.
Referring to the accompanying drawing,
Fig. 1 is a front elevation of the apparatus.
Fig. 2 a side elevation from left of Fig. 1.
Fig. 3 is a cross section along line R S, Fig. 4, showing the card bar at the
moment, it makes revolution for changing the cards after the passage, and
Fig. 4 is a plan view showing the card bar at the moment that it separates from
the needle guide bar after the passage, for making the revolution for changing the
card.
Fig. 5 represents in front view and cross section a portion of my improved card,
the slips for covering the holes, being fixed under or by leather straps or the like so
as to be movable.
Fig. 6 shows a portion of another card the cover plates being united therewith by
hinges for covering or uncovering the holes.
The apparatus consists of two frames A A and A' A¹ placed at a distance apart
according to the breadth of the apparatus and united by transverses E. On these
frames is supported the whole mechanism and together with the rails D they serve as
guides for the movement of the card bars B and needle guide bar C.
The mechanism receives its motion from the loom through a shaft F by bevel
gear F and toothed wheels G, G¹, G². The last wheel actuates the shaft H carrying
at its extremities the cranks I connected by rods J to the trunnions of the bar B.

page_text: The trunnions of the bar C run in the slots of the slotted bars K connected to the
ends of the bar B; the said slotted bars are themselves capable of longitudinally
moving, they being guided on antifriction wheels or otherwise in the fraine of the
machine.
The trunnions of the bar C receding in the slotted bar K, on arriving at the ends of
said slots, carry along said bars K and with them the bar B. On the forward return
movement of the bar C the bar B is left stationary until the bar Cabuts against it,
when both move forward together.
The bar C must also make revolution to bring a new card in front of the pins at
each rotation. When receding therefore, it abuts against the finger L Fig. 3 jointed
to the spring L, and the bar being pivoted at its extremities revolves and presents on
each movement a new face to the needles; the springs M and M' keeping the said bar
immovable during these to and fro movements. On the frame A A¹ is situated the
finger N and spring N1, which makes the bar C to revolve in the contrary direction,
when a design is to be repeated. In the latter case, the finger L is raised by pulling
the thread or by attaching a weight to it, and when the finger L is in action, the
finger N is kept raised by means of the thread n passing over the pulleys n¹.
The needles P are straight and their forward extremities terminate in small rings,
to which the heddles o are attached. The latter pass under the brass rods Q and over
the rods Q through the guide R with counter poise which holds it in position, the
heddles being held in position by small weights s.
When the bar C advances with the needle guide bar certain needles passing through
the needle guide bar, find their passage closed by the card and are driven back beyond
the brass rods Q and consequently draw up the heddle raising the warp threads
governed by them. When however the bar Crecedes, the needles are freed and
resume their first position by aid of the pressure of the weights on the heddles.
In Figs. 5 and 6 is shown the extremity of two cards with metal cover-plates. The
holes in these cards must be so arranged as to exactly coincide with the grooves of the
bar and to establish while coming in contact with the latter, a perfect corre-
spondence, the hole a is arranged into which engages the tooth 6 of the bar C. The
card Fig. 5 is furnished with four rows of cover slides attached under a band of
leather or card board or other convenient material, permitting of the slides being
moved for the purpose of opening or closing the holes. These slides are bent upward
at their extremities to allow them to be more easily displaced. The cover discs of the
card shown in Fig. 6 are hinged to a rod occupying the whole length of the card.
To uncover the holes, the disc is raised, and to cover them, the disc is caused to fall.
The cross section shows one of the discs when raised. These cards have preferably
metal rims to give them a greater strength.
If several of these cards are to be used, they are connected so as to form an endless
band c running over a cylinder d Fig. 3, whence the cards pass to the bar, and those
that are suspended, bear upon the guide z and do not impair the working of the loom,
the said cards being provided with projecting pins lying on said guide z.
Σ
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, I declare that what I claim is :
In looms:
1) The combination with the heddles of series of straight needles connected thereto
by rings at their oxtremities, said needles being supported by a movable guide bar.
2) The combination with Jacquard needles of a needle guide bar of rectangular
cross section, having rows of perforations, one for each needle, and a bar for
supporting the pattern cards, said bar having grooved faces, the grooves corresponding
to the rows of perforations in the needle guide bar.
3) The combination with Jacquard needles of a needle guide bar, having perforations
one for each needle, said guide bar being adapted to move beyond the ends of the
needles, a card carrier, having grooved faces, said carrier being adapted to be partially
revolved, to bring each succeeding face parallel to the face of the needle guide bar,

page_text: and to be moved toward and into contact with said needle guide bar and to carry said
needle guide bar forward to enable the card to impinge upon the ends of the needles
for the operation of said needles substantially as set forth.
4) A Jacquard card having perforations one for each needle, each perforation
adapted to be separately opened or closed by a cover disc for the purpose set forth.
