Application mea oeiober 17, 190s. serien No. 458,241.

To all whom t may concern:

Be it known that I, MATTI-inw J. l/Vnrr- TALL, a citizen of the United States, residing at Voi-cester, in the county of `ld/'oreester and State of Massachusetts, have invented a new and useful Method of Weaving, of which the following is a specification.

rlhis invention relates to a method of operating Jacquard looms to weave fabrics and carpets, particularly carpet rugs having both a border and a body design thereon.

The principal objects of this invention are to provide for weaving `patterns thatl are more complicated than those that have been practically woven heretofore on this type of machine, and to accomplish this result more nearly automatically than has been the case heretofore, even with simple patterns.

rlhe method is explained by the ligures` shown in the drawing accompanying this application for patent, 1n wh1ch- Figure l is a plan of a carpet rug having l a body and border design, and llig. 2 is a plan view of the arrangement of cards of the carpet loom for practising my invention. y

A form of carpet rug is now made by sewing several breadths of carpet together, which breadths are so woven with a carpet body and border design as to malte up a carpet rug. For example, in the annexed sheet of drawings, such a rug is shown as made up of four breadths iV-NV, KMX, Y-Y and Z-.Z, which breadt-hs are sewed together on the lines l--l, 2-2 and 3--3, as shown. This makes a simple and neat form of rug and one in which the sewing of the y breadths together is not noticeable, asl com pared with those forms of rugs wherein the border is woven separately and sewed to the body.

The rug as illustrated has a plurality of body elfects so that if desired, a center ligure or medallion effect can be given to the rug. In the ordinary practice of weaving breadths of carpets which are used to form this style of rug, the cards of the loom are arranged so that the border will first be woven, and then the body up to the center. This necessitates mounting in the loom when arranged to weave a breadth of the form of rug illustrated, a number of cards equal to the number of wires from the end thereof up to the center of the rug. This mass of cards is very `heavy and unwieldy and it is ditlicult to arrange a carpet loom to weave rugs of considerable length in this way. lo overcome this objection l have invented the following method of weaving by which any length or width may be woven. This method consists in arranging the cards of the border design and a plurality of body designs alternately, as for example where two body designs are employed, by arranging the cards of the border design and the cards of the first body designs and t-he cards of the second body designs alternately; in moving the cards a distance equal to three cards for each opeation of the loom so that the border design will. tirs-t be woven; then moving the cards to bring one of the sets of cards for the body desi gne into opera `tive position; then moving the cards a distance equal to three cardsl for each operation so that the lirst body designs will be woven; then moving the cards so that the cards of the secoml body designs will come into operatlve position; then moving the cards a distanee equal to three cards for each operation so that the second body designs will be woven; then moving the cards so that the border cards will come into operative position; and then moving the ards a distance equal to three cards in the same or reverse direction compared with the first step so that the border will be woven again in the same or opposite direction to which it was `first woven.

j lf the body designs are symmetrical with respect to their center, the operation canbe simplified by using a number of cards equal toene-half of the number required for each body design, and by ruiming the cards of iach body design :forward and then backward whereby only a number of cards need be employed for each body design equal to half the nl'lmber of wires necessary for each body design. AFor example, suppose the breadth lV-- V is to be woven; then A represents the cards which will produce the border design; l the cards which will produce the first body design or set of designs; and C the cards which will produce the that is, if the invention is applied to a carpet loom for each wire, the cards will be moved forward a distance equa-l to three cards length, so that cards A in the chain 5 will first be called forwardly. This will weave the section A of the breadth VV-N which may be called weaving the border forward. liVhen this section is woven, 4the card chain is ino-ved a distance equal to one card, and the loom is then set in operation forward and as this operation takes place, the card chain will be moved forward a distance equal to three card lengths for each wire. This will call the cards B and will weave a section B of the breadth lil-VV which may be called weaving the first body design forward. hen this operation is completed, the cards are set to run in the opposite direction or backward and are still operated so that the card chain will be moved backward a distance equal to three cards for each wire. This will weave section B2 of the carpet breadth Vlr-TV and may be called weaving the first body design backward. Then the card chain is moved a distance equal to one cards length, and the loom is again set in operation so that for each operation the card chain will be moved forward a distance equal to three cards. This will call the cards C of the chain and the section C of the carpet breadth VV-W will be woven, which may be called weaving the second body design forward. Then the loom is again set in Operation so that the card chain will be moved backward, but still so that the card chain will be moved three cards for each wire which will weave the section C2 of the carpet breadth lV-l/V, which may be called weaving the second body design backward. Then the card chain is moved a distance equal to one card, and the loom is set in operation so that the cards will move forward a distance equal to three cards for each wire. This will again weave the first body design forward and will give the second section B. of carpet breadth V-V. The loom is then set so that the cards will run in the opposite direction, but so that the cards will move backward a distance equal to three cards length for each wire. This will weave the second section B2 of the carpet breadth lV-Vl/T, and may be called weaving the first body design backward. The card chain is then turned a distance equal to one card, and is set in operation again so that the card chain moves a distance equal to three cards for each wire. This will weave the section A2 of the carpet breadth wW-VV which will be the border design woven backward. Thus a carpet rug will be woven having the patterns thereon as shown in the drawings. In a similar manner the breadths X-QQ Y-Y, and Z-Z can be woven. This method of weaving and setting the cards greatly simplies the operation and leads to the simple and easy production of carpet rugs and other fabrics.

Tn some cases the cards for the border may be divided so as to give two separate half effects; that is, one-half of the border cards are first used to give one border effect, which will be one-half the length A shown in Fig. l; then the bodyl designs are woven, and then the second half of the border cards are used to give the border effect at they other end of the length, which will be one-half of Vthe length A2 shown in the drawings, whereby the borders may be varied in design and color effect.

The essential point of my new method is arranging the cards of a border design alternately with the cards of a plurality of body designs and moving the card chain when weaving for each operation a number of cards one more than the number of body designs employed.

Many mechanisms. may be arranged on a loom for weaving the cards in the manner described.

Having thus fully described my method of weaving, what l' desire to secure'by Let ters-Patent is:- Y

1. The method of weaving a length of carpet which consists in arranging successively three series of pattern cards in an endless chain, each card having a plurality of rows of perforations, all of said series containing the same number of cards, running the pattern cylinder forward through one yseries at a time by moving the cards afdistance equal to three cards at each operation, so as to stepY over two cards at each movement, when any series has been finished setting the pattern cylinder to commence on the next adjacent card of one of the other series, and operating forward so as to step over two cards at each movement. l

2. The method of weaving a complete length of carpet on a Jacquard loom, which consists in arranging successively a series of pattern cards for a border designand a plurality of series of cards for body designs in an endless chain made up of a plurality of identical sections, each containing a card belonging to each design arranged in the same order in each section, running the pattern cylinder through one series at a time by moving the cards at each operation a dis-V tance equal to the combined width of a card of each series so as to step over a plurality of cards at each movement, when each series has been finished, setting the pattern chain foi-'Ward o1- hzwk :L distance less than the In testimony whereof I have hereunto set combined Widths of a card of each series so my hand, in the presence of two subscribing as to commence on one of the other series Witnesses.
