ELECTRIC JACQUARD MACI-IINE m. rreonn-wnavme WITHOUT CARDS.

Application filed December Improvement in and Relating to Electric Jacquard Machines for Figure Weaving \Vithout Cards, of which the following is a specification.

This invention relates to an electric jacquard machine for figure weaving without cards, of the kind in which the electromagnets which control the hooked wires of the harness leashes are operated by means of a pat-tern card on which the figure is drawn, without taking into consideration the binding of the fabric,in such manner that either the said figure is an electric conductor, and the background is not electrically conducting, or vice versa, while the binding for the background of the fabric, and also that for the figure, is produced by a special background-and figure-binding-device.

According to this invention, the background-and figure-binding device of the jacquard machine works in such manner that, as long as the contact pin or stud is" in confact with the background of the pattern, a background-binding pat-tern card effects the selecting of the hooked wire magnets, while when the said pin is in contact with the surface ofthe figure of the pattern card all the selecting points of the background binding card are rendered conducting, so thatthe binding effect of the card is annulled,

This invention relates to a special construction of the binding card with its canceling or annulling device.

A construction according to this invention is illustrated by way. vof example inthe accompanying drawing, in which Figure 1 shows the most important parts of the jacquard machine in diagrammatic perspective; Fig. 2 is a diagram illustrating principally the electric Wiring; Flg. 3

card, which, according as they touch the conillustrates a detail of in side elevation; Figs. 4 and 5 ducting or the non-conducting portions of the pattern card, close or open the circuit of the source of current 6. In the said circuit moreover, are inserted electro-magnets d the number of which corresponds to the number of the hooked Wires to .be controlled. The electro-magnets d act on armatures which, on the electromagnets being excited, are attracted, and moving laterally out of engagement with the notches d in the magnet housings d are thereby brought into a position in which they come with their ends into the path of lifting fingers h secured to rolls ers g. The said lifting fingers h are of such shape that, on the rollers g rotating, they press downward armature levers in opposition to the action of springs d which automatically return the armature levers to their normal positions 1'. 6., engaged in the notches d after the action of the said fingers has ceased. Tothe armature levers are connected cords 71 attached to the ends of bell crank levers j, the second ends of which are connected to the cross-wires or needles is controlling the hooked wires. The cords 71 secured to the armature levers f, could also be connected direct to the harness leashes of .the warp threads, so that the electromagnet armatures cl and the lifting fingers 72, could act direct on the warp threads.

When a conducting point, of the pattern card it touches a contact Stud 0, the corresponding electromagnet d is excited, and its armature lever attracted, so that the latter comes into the path of a lifting finger it of a roller 9, and on the latter rotating, is depressed. pulled down, and the cross wire or needle is connected to the same, moved. The corresponding hookedwvire Z is thus disengaged moved during the upward movement of the card a (Fig. 1) made of an electrically conducting material they repeat is not raised.

into the circuit of which are inserted contact pins or studs 0 traveling over --the pattern At.-. the same time the cord 2' is from the riff, so that the former is not rifi m, andthe corresponding warp thread which, on the rotation of the arm p, closes the circuit into which the electromagnets are switched, by connecting the ring to one of the contacts of the contact series 12, and in that way consecutively switches in all the electromagnets (5 into the circuit of the source of current. Into the said circuit containing the pattern card a, the electromagnets d and the switch n, 0, p, is also switched in a binding device, for enabling the binding to be effected in the background and in the figure of the .pattern to be woven.

The pattern card makes both a longitudinal reciprocating movement and an intermittent rotation. After each longitudinal movement in one or in the other direction an intermittent rotation of the ,pattern card takes place, so that the contact pins come into contact with the next series of the pattern card. If during the longitudinal movement of the pattern card a, one ofthe contact studs or pins 0 comes on to a conducting point of the pattern card, and at the same time a connection is made between a contact of the series n and'the ring 0 by the contact bridge q during the rotation of the arm p, and the circuit thus closed, the armature lever of the corresponding electromagnet d switched by the contact bridge q into the circuit of the source of current 1), comes into the position of operation in which, as alread stated, the armature is moved, whereby the corresponding hooked wire I is disengaged from its grifl' m so that the corresponding warp thread in the fabric remains undisturbed.

In order to enable the required binding or weaving to be given to the background, as well as to the figure of the fabric, a special device is provided, the substance of which will be seen from Figs. 1 and 2. As an example, it has been assumed,- for explaining the device, that the background of the fabric is to be woven in linen binding while the figure in a bindingcorresponding toeight leaf twill. The pattern card is made in such manner that the background is electrically non-conducting, while the figure is conducting. The electromagnets d are consecutively connected to the contacts of the switch board w (Fig. 2), arranged in a circle, the said switch board being provided with so many contacts n that halfv of the same corresponds to the number of the electromagnets al used. Moreover, there are provided two resting points r arranged between the upper and the bottom half of the contacts. The sequence of the contacts of the bottom half is exactly the opposite of that of the contacts of the upper half, so that,

when. for instance the last contact 8 of the upper half of the contact series a. is cornected to the last (counting from theleft) electromagnet 8' for the warp threads of the background the first contact of the bottom half of the contact series a, following the resting point r, isconnected to the last contact 8" of the upper half of the contact series, and therefore, also to the last electromagnet 8" of the electromagnet series for the warp threads of the background. In that way, a continuous rotation of the arm p is rendered possible with the reciprocation of th'e pattern card. While the bridge 9 connects the contacts of the upperhalf of the contact series n, one after. another, to the bar 0, the longitudinal movement of the pattern card a takes place in one direction and, therefore, one series of contact points is touched by the contact studs or pins 0. While the contact bridge 9 is moving from the contact 8" over the rest contact a" to the next contact 8" of the bottom half of the contacts n, the intermittent rotdtion of the pattern card a takes place, so that the contact studs '0 can engage with "the next weft .line ofthe pattern. While the pattern card moves back in the direction opposite to the first movement, the contact bridge 9 slides ,over the contacts of the bottom half of the contact series n of the switch board to, connected to the electromagnets consecutively, -but iii-the reverse sequence to that of the contacts of the upper half, as shown inFig. 2. The electromagnets d are connected to the bars s's (Fig. 2) provided with a series of binding screws, so that the connection can be altered at will. lVhen it is desired to effect the binding of the figure in eight leaf twill, the electromagnets d are divided into groups of eight magnets each. To the first bar 8' are then connected the first electromagnets 1, 1, 1 etc. of each group, to the bar 8 the electromagnets 2, 2', 2", etc. up to the last bar 8 to which are connected the electromagnets 8, 8, 8". For

suitably switching in the electromagnets for J the binding of the ground, is provided a reversing switch of well. known construction consisting of two systems t't and u u completely insulated from each other, of intersecting curreht conducting bars which are perforated at the points of intersection, so that an electric connection can be effected at these points by means of contact studs '1) or the like. As the pattern ground in the example selected is to be boundin linen binding or twill, all the electromagnets d which are to be marked with even figures in their sequence, are connected to one barrand the magnets marked with uneven or odd figures, to a second bar. In that way, all

the barst t t t which would bemarked in A their sequence with odd numbers are conon a binding cylinder y. The latter is mounted on and insulated from the spindle connected to the source of current I), while the binding cylinder y is connected I to the'source of current I).

The spindle z carries, in the case of the.

binding selected, two series of contact studs A and A (Flgs. 4 and 5) which are lnsulated by the bores B and B -of the binding cylinder y and project from the same. The binding cylinder y and the spindle ,2 with the contact studs A and A are made of electrically conducting material. The con-.

tact studs A and bores B in accordance with the binding, so that, when aQsliding contact cc slides over one of'the contact studs, the sliding contact m is situated between two consecutive studs A or bores 13 on a conducting point of the binding cylinder 3 In that way, during the rotation of the binding cylinder at one time all the electromagnets marked in their sequence with even numbers and another time all the electromagnets marked with the odd numbers are alternately switched into the circuit of the source of current I) and excited when the contact stud 0 is on a non-conducting point of the pattern card a, and thus the source of current 6 is switched out. Accordingly all the even, and all the odd warp threads, remain alternately without change, whereby the warp threads forming the background are bound in the linen twill fashion.

If. on the contrary, the contact stud c is on a conducting point of the pattern card, then, in the case specified, the sliding contact m which slides on one of the contact studs A will be switched into the circuit of the source of current I) connected to the spindle z, and the sliding contact m which touches the conducting surface of the binding cylinder, into the circuit of the source of current b. In that way the electromagnets of the even and of the odd warp threads of the pattern, will be excited, and consguently all the threads of the background will be left unlifted, while the lifting of the figure threads will be effected by operating a rod which controls several heddles or leashes so that they may be simultaneously operated as will be hereinafter explained.

Fig. 2 shows the binding of warp threads of the background, as the contact stud 0 on the pattern card a touches a point of the ground, that is to say, a non-conducting point. The source of current 6 is, therefore,

switched out of the circuit, but the source of current I) is switched in. The current passes from that source of current 6 to the ring 0 of the switchboard '10, and on the arm p being moved, through the bridge 51 and the consecutive contacts n to the electro magnets d through the bars ss",- and through the bars tz into the bars u and u. As at the moment in which the single parts are in the position shown in Fig. 2,

the sliding contact 23 touches a pin A ,;the bar a and therefore, all the even electromagnets are switched out from the circuit of both sources of current '0 and 1). Consequently none of the electro-magnets marked with even figures, is affected. The corresponding hooked wires remain within reach of their grifi's, so that all the even warp threads are lifted. The sliding contact .r which touches the conducting. surface of the binding cylinder, is switched into the circuit of the source of current b. Thus all the odd electromagnets are excited and bring the corresponding hooked wires out of reach of their grifis, so that the corresponding Warp threads are" not lifted, while at the next moment, after the intermittent rotation of the binding cylinder has taken place, the contrary process takes place.

v The lifting out of the warp threads forming the figure, is effectedby means of the electromagnets IVIII and IVIII which, for the sake of clearness, are shown in the drawing next to each other, while in reality, they are arranged at the points where the reserve hooked Wires are arranged in each series of hooked wires. As it is intended to bind the pattern in a manner corresponding to the eight leaf weft twill,

one eighth of the threads must always remain in the background, and one eighth of the threads must be raised into the upper shed.' In order to avoid the necessity of making therods too heav each pair of rods contains one-eighth of the threads, that is to say, one rod which is operated by an electromagnet, carries one-sixteenth of/the threads. Each two of these electromagnets I I etc. to VIII VIII are switched in series, so that a pair of rods, that is to say, one-eighth of the warp threads, are operated simultaneously. The electromagnet pairs 1' I'VIII VIII are connected to the sliding contacts CC which slide along the bind ing cylinder 3 In the latter there are provided eight series of bores D-D- which are arranged alternately, in such manner that the sliding contacts CC' on the binding cylinder rotating, slide consecutively over each bore D-D The distance between the bores in the single series is calculated in slide contacts can touch at times the conducting binding cylinder, while one sliding contact slides over a bore of the same, that is to say, over a non-conducting portion. At the moment to which the position of the single parts shown in Fig. 2 correspond, the contact stud C touches, as already stated, a

v non-conducting portion of the pattern card.

, of current I). The corresponding electromagnets of the rods are not excited, and therefore the reserve hooked wires with the rods are raised by the gritfs and thus the eighth of the pattern warp threads corresponding tothe binding, is lifted out for binding the ground. If, on the contrary,

-' the contact stud 0 were in the position shown dotted in Fig. 2, the figure warp threads would have to be lifted out,- so as, to bind one-eighth of the pattern warp threads for producing the pattern. The binding device regulates which one-eighth of the pattern warp threads is to be lifted out.

The arrangement of the jacquard machineon the weaving loom is illustrated in Fig. 3 of .the accompanying. drawing. The drivin of the jacquard machine is effected from t e'crankshaft 9 of the weaving loom, onwhich next to the belt pulley is mounted a chain wheel 10. The latter transmits the movement of the crank shaft 9 by means of chain and chain wheel 11, to the-spindle 12 driving the pattern card a'and carrying two chain wheels 13 and 14. v

.The longitudinal movements of the pattern cylinder (rare accomplished by the means shown in 'Figs. 3 and 3, where 12 is a spirally grooved cylinder receiving a projection 12 of a yoke 12 which is penetrated by the "shaft 13 carrying the pattern cylinder and which is confined for move ment in the longitudinal direction withsaid shaft by a collar .13 which is fixed on'said shaft and receives the yoke.

The chain wheel 13 is positively connected to a chain wheel 15 mounted ona spindle16,

which operates therollers g for the electromagnets 03 by.means of a connecting rod 19 and cranks 20. The chain .wheel 14 is connected by means of a'chain to a chain wheel 17 mounted on the spindle 18 of the switch lever go. The ratio between the chain wheels 14 and 17 is 1:2 as at one revolution of the spindle 12 the pattern card makes a longitudinal movement in one direction, but the .arm p must make d'urin the same timeonly half a revolution, that is to say, slide only above the crank shaft 9 of the weaving loom and below the said device is arranged the switch board w.

In the construction of the electricjacquard "machine illustrated only one'series of hooked wires are shown, and therefore, only one contact stud 0 for the pattern card. In practical construction of the device there is foi each series of hooked wires, a series of electromagnets with .a corresponding switch w and contact pin c, while only one binding cylinder, one pattern card and one reversing switch, cooperates with the said parts of the device.

Having now particularly described and ascertained the nature of my said invention,

and in what manner the same is to beperformed, I declare that what I claim is:

'1. The combination, with a series of electro-magnets to be controlled corresponding in number to the warp threads to be actuated, of a series of conductors electrically including said magnets, two other conductors m electrically connected the one with alternates of the magnet-including conductors and the other with the remainder there of, said 1 magnet-including conductors terminating ina series of separate contacts,'a single contact adjoining the first-named contacts, a switch movable over the single contact and simultaneously over the series of contacts in succession, electro-conduct-ive means, comprising a source of electric energy' and a movable switch-member, for alternately' connecting said conductors m with the single contact, other electro-conductive means comprising another source of elec trio-energy, a movable ,pattern cylinder havmg electro-conductlve and electro-non-conductive surface portions, and a contact piece engageable with said portions of the pattern member, for electrically connecting either of the conductors m with said single contact when the other of the said conductors a: is not connected with the single contact by the first-named electro-conductive means, and means for ggcting the? movement of the pattern cylin r and the switch and switch-member, substantially-as described.
