TE STATES PATENT FFTQ 1 AUGUST REGAL, OF VIENNA, AUSTRIA-HUNGARY.

ELECTRIC JACQUARD APPARATUS.

To all whom it may concern:

Be it known that I, AUGUST REGAL, professor, a subject of the Emperor of Austria- Hungary, and resident of Vienna, in the Empire of Austria-Hungary, and whose post-oflice address is No. 52 Weissgarberla nde, third district, have invented certain new and useful Improvements in or Relating to Electric Jacquard Apparatus, of which the following is a specification.

This invention relates to an electric jacquard apparatus with positively controlled cross-wires, which differs advantageously from the well known constructions of similar kind as it requires only very small space avoiding completely the usual intermediate elements operating the cross-wires, and considerably reduces the consumption of current. In addition to the advantage that only small space is required is combined at the same time the advantage that the apparatus can be easily inspected and all the single parts of the apparatus are readily accessible. This is effected by the cross-wires engaging with the hooked wires, being controlled by coils or electromagnets with preferably horizontally adjustable cores, excited consecutively and synchronously with the movement of the contact pin on the pattern card, the said magnets preventing or allowing the movement of the cross-wires and consequently the driving of the same by the grifl -blades or knives controlling them. The cores of the coils are designed in such a manner, for instance in the shape of a V, that when drawn into the perforation of the coils, they become jammed therein, for instance, owing to the ends of the branches being near together and springy, and cannot spring automatically into their initial position, but are brought back to the same by a reciprocating regulator or like means which operates all the superposed cores.

Figure l diagrammatically illustrates the several parts of the improved jacquard apparatus; Fig. 2 is a similar view showing the parts in different positions; Fig. 3 shows one of the magnets and its armature core separately, together with the bar 'w for cont-rolling said core; Fig. 4: is a perspective view showing one of the cross-wires and the actuating bar 6 normally supporting the same; Fig. 5 is a diagram illustrating the binding of the ground and pattern; and, Fig. 6 shows the surface of the binding cyl- Specification of Letters Patent.

inder in plan together with certain contacts 0 to O The coils operating the cross-wires of the jacquard machine are of such shape that in the perforation of each coil Z), there is arranged an armature core 0 having the shape of a V the ends 0 of the branches of which are arranged close together and are resilient, so that they jam with a slight friction in the perforation a of the coil. The core 0 of the coil, when no current is passing through the winding, is situated under the end of the corresponding cross-wire 03, whereby a descent of that wire is prevented (Figs. 1 and 2). When current is sent through the winding of the coil, the core 0 is drawn into the perforation a and thus brought out of the path of the cross-wire (Z (Fig. 2). The cross-wires d of each row are situated in recesses s of a supporting bar t which can reciprocate vertically and in the horizontal direction. Each crosswire, which is bent to a U-shape, is resilient, and provided with a projection to arranged in front of the supporting bar t and with a bend c which surrounds the corresponding hooked wire n. On the pattern card 9 connected to a source of current 7, is drawn the pattern of the design to be woven, without regard to the binding, in such manner that the back-ground of the design is conducting, and the design itself not conducting, or conversely. Into the circuit of the source of current f are moreover switched in contact pins h traveling on the pattern card 9, the said pins, according as they are in contact with the conducting or non-conducting portions of the pattern 9, closing or opening the circuit of the source of current f. The circuit comprises moreover a contact bar 2' along which travels a contact wheel 7' synchronously with the contact pins'h. The latter make a reciprocating movement along the pattern card which, after each longitudinal movement in one or in the other direction, is intermittently rotated. On the bar 2', contact portions alternate with non-conducting portions, so that the circuit is quickly broken after each closing of circuit efiected by the contact wheel touching a contact of the bar 71. The coils b of one series are connected to the contacts of bar 2' which consequently has as many contacts as there are coils or hooked wires in one row. In practice the pattern card has several contact pins h with each of which is combined one contact wheel j and one contact bar 2'. According therefore to the number of the contact pins it used, several points of the pattern card are simultaneously touched, and as many contact wheels shifted on the same number of the contact bars 2', in order simultaneously to operate a number of contact pins h of the pattern card and an equal number of rows of coils and hooked wires. In addition to the contact wheel j, there travels along each bar 2' a second contact wheel 70 to which is connected a second source of current m. i For obtaining the binding when coils are used, both in the ground and in the pattern, in the manner shown in the binding diagram in Fig. 5, as the pattern has to be woven in a manner corresponding to an 8 leaf warp body, the windings of each eighth of the coils b are connected by means of a switch 0, to one of the contacts C 43 For that reason the coils 1, 9, 17, 23 are connected to the contact C the coils 2, 10, 18, 26 to the contact C the coils 3, 11, 19, 27 to the contact C and so on, the coils 8, 16, 2 1, 32 to the contact C The contacts C -C slide on a binding cylinder 'y which is mounted on the cylinder .2 and insulated therefrom, the latter cylinder being connected to the second source of current m. The cylinder 2, like in the machine according to the Patent No. 983,862, is provided with contact fingers A A which project through the perforations B of the binding cylinder y and are insulated therefrom, the said cylinder y, like the cylinder 2, being provided with contact fingers of electrically conducting material. In the linen binding (Fig. 5) selected for the ground, one row receives four contact fingers A, and the contact fingers of each two consecutive rows are arranged alternately to each other. One row contains the contact fingers A A", A and A for the contacts C C C and C marked in their sequence with odd figures and the second row contains the contact fingers a A, A and A for the contacts 0 0*, C and C marked with even figures. When the binding device rotates, the coils marked in their sequence with odd, and those marked with even figures are therefore alternately switched into the circuit of the source of current m connected to the cylinder 2.

As the pattern has to be woven, as already mentioned, in a manner corresponding to the eight leaf warp body, each eighth warp thread of the pattern must always remain lying in the ground. For that reason, the binding cylinder is provided with eight rows of perforations D D arranged alternately to each other in such manner that the 1 contacts C -C slide consecutively over each one of the perforations D D when the binding cylinder y is rotating. The perforations in each row areso spaced from each other that after the contact for any row has been passed by one perforation it does not reach the next perforation in that row until perforations corresponding to the first-named perforation in the first-named row have been passed by the contacts appertaining thereto Owing to this arrangement, it is possible for seven contacts to touch atany moment the conducting binding cylinder, while a contact slides over the perforation D of the same, that is to say, over a non-conducting portion.

Then a contact pin it is in cont-act with a conducting point of the pattern card 9, all the coils, the contacts of which slide along the binding cylinder 1 will be supplied with current from the source of current f, and accordingly the cores 0 of the coils will be drawn out of reach of the cross-wires (Z (Fig.2). The coils which are connected to a contact sliding on a perforationD (or on an insulated portion of the outer binding cylinder y,) do not, on the contrary, become energized. If, after the adjustment of the cores of all the coils, the supporting bars 6 of the cross wires cl are moved downward, the cores 0 of the coils Z) without current will hold elevated the corresponding crosswires out of the reach of the bars 25 in the new position of the latter. The crosswires cl of the coils through which current is passing, will on the contrary follow, owing to their resiliency, the supporting bar If during its downward movement. If now all the sup porting bars t are advanced to the right (Fig. 2), they will press against the projections u of the crosswires d which have moved down, and deflect the hooked wires 1 wire in Fig. 3) so that the corresponding warp threads will remain in the ground. The cross-wires prevented. from moving down by the cores 0 of the coils, are of course not afiected by the horizontal movement of the supporting bars 2, as the latter are below and out of reach of their projections. If, on the contrary, a contact pin it touches a non-conducting point of the pattern card 9, no current will be sent into the coils from the source of current f, the magnet cores 0 will not be drawn in, and consequently the cross-wires (Z of the corresponding hooked wires 72 will not be shifted during the advance movement of the supporting bars t, and the hooked wires will not be moved away from the griif blades or knives. The corresponding warp threads will therefore be lifted, as required. These coils Z) on the contrary, the contacts 0 of which come into contact with the contact fingers A of the cylinder 2, will not receive any current from the source of current f, but on the contrary will be supplied from the source of current m, so that the cores overcome a slight friction.

of the coils will be drawn in. Accordingly, the corresponding hooked wires 11 will be moved away from their knives Z during the movement of their cross-wires (Z, the corresponding warp chains will not be lifted out, and the binding of the backing will be effected.

Owing to the resiliency of the ends of the branches C of the cores of the coils the latter, on being drawn into the perforation of the coils, will remain in the same without any reaction shock which might prevent a return of the core and consequently produce a fault in the fabric. Through all the superposed cores 0 of the coils passes the bar 20, or suitable regulating means which brings about the return of the cores to the initial position. The return of the cross-wires d is effected by a cross-wire regulator 09.

After the supporting bars 23 have been moved forward, they are all simultaneously moved backward, and then upward. Simultaneously with the return movement of the supporting bars in the horizontal direction, the corresponding movements of the crosswire regulator w take place and that of the straightening bars 10 or of the regulators of the magnet cores.

An important advantage of this jacquard machine consists in doing away with any intermediate cross-wires or other intermediate elements which in well known constructions transmit the action of the coils or electromagnets to the crosswires. This advantage is of the greatest importance in view of the very large number of parts which in any case are required for a jacquard device. Apart from the fact that, owing to the removal of so many parts, it is easier to inspect the device readily and the cost of manufacture is reduced, the reliability of working being brought to a maximum. The most important advantage of this invention consists however in the reduction of the work to be performed by the coils. The coils in the jacquard apparatus according to this invention have no other work but to shift their own horizontal core, that is to say, only to Moreover, in view of the specially favorable arrangement of the core, since its end projects into the perforation of the coil, only a minimum of work is required, as a short and comparatively weak current impulse is sufficient and it is not necessary as in well known constructions, to overcome any counter-force. Moreover, the core automatically retains its end position at any moment, that is to say, during the time it remains in that posit-ion, it does not consume any current, while in the well known devices, in which for the purpose of moving the parts controlled by the coils, it is necessary to overcome a counterforce, a consumption of current must take place in order to keep the said parts in their end position. A very considerable saving of current is insured, moreover, by exciting the coils in the present case consecutively and synchronously with the movement of the contact pin along the pattern card, as in that-way the source of current is subjected only to the above mentioned strain which lasts only a short time, that.

is to say, at any moment, it has to supply current only for one coil, which advantage cannot be obtained in any of the well known devices. This considerable saving of current obtained with the jacquard apparatus according to this invention, is of all the greater importance owing to the large number of coils required.

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 2- 1. In an electric jacquard apparatus, the combination of a vertically movable grifi, hooks to be raised and lowered thereby, cross-wires arranged substantially horizontally and operatively connected with cor responding hooks and movable up and down relatively thereto, each cross-wire having a depending projection, means for moving the cross-wires horizontally comprising bars normally supporting the cross-wires and engageable with their projections, said bars being movable vertically and horizontally, armature cores projecting under the respective cross-wires and normally preventing their downward movement with said bar, electro-magnets controlling said cores and adapted to move them from under the crosswires, an electric circuit including said magnets, and means for making and breaking the circuit, substantially as described.
