METHOD OF REPEATING JACQUARD-CARDS.

Specification of Letters Patent. Patented June 11, 1918.

Application filed January 29, 1918. Serial No. 214,386.

To all whom it may concern:

Be it known that 1, FRANK FISCHER, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Methods of Repeating J acquard-Cards, of which the following is a specification.

This invention relates to the art of preparing jacquard cards, and it consists in a novel method of forming such cards for the weaving of certain fabrics whereby onehalf of the tedious, slow and expensive work of primary orhand-cutting of cards from a design sheet or chart is avoided.

In the accompanying drawings,

Figures 1 and 2 show pieces of figured fabric having the figures in rows and the figures in any two adjoining rows staggered, Fig. 1 showing the figures all arranged substantially the same, but Fig. 2 showing the figures in any two adjoining rows relatively reversed;

Fig. 3 shows a blank jacquard card in the position for reading it according to the progress of hand-punching the same;

Fig. 4 shows two cards in position for reading them according to their progress through the jacquard machine in weaving, the two cards being punched for use in producing a plain tabby (or taffeta) weave;

Fig. 5 shows a set of pairs of cards for use in weaving a fabric having rows of figures and a tabby background, each pair being a counterpart of the pair shown in Fig. 4 except for the figure punchings therein:

Fig. 6 shows the punching field of a jacquard card repeating machine;

Fig. 7 shows, a set of cards that would be produced if, using as master cards the set of cards shown in Fig. 5, a set of blanks were passed through the repeating machine in the direction of the arrow B in'Fig. 6, or relatively reversely to the direction of the master set;

Fig. 8 shows the set of cards shown in Fig. 7 reversed end for end and joined to the set of cards shown in Fig. 5. i

Fig. 9 shows thepunching points .in two of the cards in Fig. 8, specifically and for example cards 1 and 1 in groups and also developed in each instance in a straight line. this view showing how corresponding cards in the two sets as combined in Fig. 8 would not both call odd or both cell even threads when used in weaving but one would call the odd and the other the even threads;

Fig. 10 is a diagram illustrating how I connect up the needles and punches so that, using the set of cards shown in Fig. 5 as master cards in a repeating machine and passing a set of blanks through the machine in the direction of the arrow B in Fig. 6, each card in the set of repeated cards thus produced and then joined with the master cards to form a string for use in the jacquard machine would call the threads in weaving (that is, odd or even) the same as the corresponding card in the master set; and

Fig. 11 shows the punching points of the set of the thus repeated cards in a group and also developed in a straight line.

Very commonly fabrics have figures woven in them which are arranged in rows across the goods so that the figures in the alternate rows stand in staggered relation to the corresponding figures in the remaining rows, for instance as shown at a in Fig. 1 of the drawings. To produce such a fabric one-half of the string of cards is used for working out the fabric asto each traverse portion thereof including one of the alter nate rows of figures and the other halffo-r' working out the fabric as to each transverse portion thereof including one of the remaining rows of figures. In such a case, there is only one primary cutting operation (hand-cutting from a design or chart) necessary, to wit, that for one-half of the cards; the other half of the cars can be and is frequently produced in a repeating machinein which the first half are used as master cards by arranging them in the machine so that if the design is, for instance, developed on. the right-hand 'ends of the master cards it will be developed in repeating on the left-hand ends of the other cards.

There are many fabrics, however, in. which the figures, all having the same configuration or shape, are not only staggered as regards adjoining rows but have. as in Fig. 2, the figures in any two adjoining rows reversed; thus, in Fig. 2, the figures in the rows designated a point to the right whereas those in the rows designated 7) point to the left. In such cases, it has heretofore been impossible, after hand-cutting from a chart or design the cards neces* sary for producing in weaving the" rows a of Fig. 2, to avoid again hand-cutting to produce the cards for use in weaving the rows of figures b, but the slow and expensive operation of hand-cutting has had to be done twice.

According to this invention, the hand-cutting from a design or chart of the cards necessary to produce the fabric shown for example in Fig. 2 requires only to be done once. When the necessary cards for producing one of the rows of figures, as a, have been completed they are used as master cards in a repeating machine to produce other cards for working out the parts of the fabric including the rows '7) and this, moreover, so that threads of the same color as form the figures a. will go to form the figures b (i. 6., if the ground of the fabric is mixed blue and black, for example, and the warp-threads which. are to form the figures are blue, the blue warp will appear for both the figures a and 5).

Before explaining my invention it may be remarked that jacquard cards are usually handcut in rows which extend transversely and read from right to left, row after row from the top of each card, the No. 1 point (upper right-hand corner, Fig. 3) corre sponding to the No. 1 warp thread and the last'point (lower left-hand corner, Fig. 3) to the'last Warp'thread. (The +-marks in Fig. 3 denotepunchingpoints, and may be punched or left blank, according to the re quirements of the Weave.) It will be apparent that this arrangement is such that when the card is turned for reading from the right in Fig. 4: (as it would pass through the'jacquard machine in weaving) upward through the successive rows the punching points in the odd and even longitudinal rows in the card will correspond to the odd and even threads, respectively, in the fabric; thefresultyin use, isthe same as it would be'if-the several odd rows were all in one line and the several even rows all in another, or' odd and even all in one row, alternating. In a plain-tabby (or taffeta) weave if a jacquard machine were used for such a simple fabricthere would theoretically be needed only two cards, one having the punching points punched in v all the even rows and the other the punching points punched in all the odd rows as in Fig. 4L, so that, in weaving, one would call the even and theother the odd threads. In a fabric like that of Figs. 1 and 2 the'background orbody, indicated at 0, is very frequently tabby or some such simple effect, and the series of cards necessary for developing the figure shown (whether a or 6) would have cards at regular intervals therein all punched alike for the weaving of the ground++in the case of tabby every other cardwvould have'the even rows, and the remainingcardsthe odd rows, punched; for

example, the pair of cards shown in Fig. i would have as many succeeding counterparts, so far. as the area thereof devoted to the ground is concerned, as would be re quired to make a'series that would develop the figure. This is shown by Fig. 5, where it willbe seen that all the punchingpoints but those on the odd cards at d (which punching points are shown heavier than the rest, as involving the figure) alternate in regular order in the successive cards, the first card having the even rows punched, the second card the odd rows, and so on, alternately. For the sake of explanation, we will hereafter assume that the odd rows are devotedto the odd threads and the even rows to the even threads in the fabric, and that the odd threads are black and the even threads blue; further, that the blue threads are tobe floated to form the figures.

Fig. 6 shows thepunching field of a jacquard card repeating machine. Of course, if the set of cards shown in Fig. 5 were used as master cards in such a machine, the blanks repeated would be developed the same as in-Fig. 5, provided the progress of the blanks were according to arrow A in Fig. 6, that is, forward, or in the same relative direction as the master cards progress. But if the progress of the blanks were in the direction of arrow Bin Fig. 6, that is, backward, or relatively contrary to the direction of progressof the master cards, it will be seen that the product would be as in Fig. 7, in which the cards '1, 2 8" correspond tothe master cards 1, 2 8, respectively, (the figure punching of the two sets of cards is indicated in Figs. 5 and 7 by heavier lines). It will further be seen that if the set of repeated cards of Fig-.7 Were reversed end for end and joined tothe master cards of Fig. 5, asin Fig. 8 (the proper number of plain tabby cards without figure-being interposed, as at e, to takecare j of the transverse plain strips of the fabric marked 7 in Figs. 1 and 2), and the string of cardsthus produced used in a jacquard machine in weaving, boththe. figures a andb of Fig. 2 (of the same configuration, but reversed) Would appear in the fabric. j

It may now besaid that my invention involves repeating in a set of blank cards in a repeating machine the punched design of another set of cards usedas a patternor master set in suchmachine, passing the first set through the machinerel atively reversely to the direction of progress of the master set (or replica thereof) to form a single string with the leading end of one next the tail end of the other. 7

But with a set of cards punched as in Fig. 8, whereas rows offigure s 6 would of course be woven in of the same configuration as and the reverse of the rows of figures a, there would be the difliculty that the color of threads called by any card in set 1 8 would be the opposite of that called by the corresponding card 1 8; thus card 1 calls black (the odd) threads, whereas card 1 calls blue (the even) threads. This will perhaps be clearer on reference to Fig. 9 which shows the punching points in the two cards 1 and 1 in groups and also developed each in a straight line. The even-numbered punching points'in card 1 are now (on account of having reversed the punchings in the set of cards 1 8 in the odd row positions. The card 1 will therefore call blue instead of black; the same will of course be true of all the other cards in the set 1 8 Consequently, instead of the figures I) being developed blue (like figures a), they will be of course developed black.

To avoid this difficulty I provide a repeating machine having a set of punches (as in Fig. 6) and a set of needles to control said punches and be operated by the master cards shown in Fig. 5, the same as would be the case With any ordinary repeating machine, but, instead of connecting the punches with the needles that correspond innumerical order therewith (thus: punches 1, 2, 3, 4, 5, etc., with needles 1, 2, 3, 4, 5, etc.), No. l punch is connected with No. 40 (or the last) needle, and punches 2, 3, 4, 5, etc., are connected with needles 1, 2, 3, 4, etc., respectively, the blanks to form the repeated cards being run through the machine backward, i. 6., reversely to the direction of progress of the master cards. In other words, there .is in effect a shifting of the connections one point throughout, so that instead of the odd and even numbered punches being connected with the odd and even numbered needles, the odd and even numbered punches become connected respectively with the even and odd numbered needles.

Such an arrangement of the punches and needles and their connections is diagrammatically shown in Fig. 10, Where to avoid confusion only a few of. the connections appear, being designated 9.

The result of this arrangement is shown by Fig. 11, where it will be seen that the blank (-1-) marked 40 in card 1 in Fig. 9 has been transferred to the opposite end of the line and all the other blanks and punches shifted to the right one point.

With the whole series of cards to be repeated operated upon in a machine thus organized as to its punches, needles and their connectors in the way hereinbefore explained, to wit, by passing the blanks for cards 1 8 backward through the machine, or relatively reversely to the direction in which the master cards proceed, and the cards 1 8 connected in the same string with the cards 1 8 the weave where the figures b are contained will be exactly like that where the figures a are contained, color for color and in every other detail, excepting that the figures will be reversed.

Having thus fully described my invention, what I claim as new "and desire to secure by Letters Patent is The herein described method of repeating jacquard cards which consists in feeding master cards past and so as to selectively actuate the needles of a jacquard card repeating machine having its needles controllably connected in the following order with the punches, to wit: needles 1, 2, 3, 4, 5 and so on with punches 2, 3, 4, 5, 6 and so on, respectively, and the last needle with the first punch, and passing the blank cards to be repeated past and so as to be selectively punched by the punches in the direction relatively reverse to the direction of feeding the master cards, whereby the repeated set and the master set of cards, when connected in a single string with the leading end of one adjoining the tail end of the other and employed as a pattern in a jacquard machine in weaving, will produce in the fabric Woven relatively reversed counterpart figures all composed of either the odd or the even threads of the warp.

In testimony whereof I aflix my signature.

FRANK FISCHER.
