PILE FABRIC.

SPECIFICATION forming part of Letters Patent No. 411,085, dated September 1*?, 1889.

Application filed November 22, 1887. Serial No. 255,895. (No model.)

.T0 all whom, it may concern.-

Be it known that I, WILLIAM HENRY BAIE- sTOW, a subject of the Queen of Great Britain and Ireland, residing at 29 East Castle Street, Bridgenorth, in the county of Salop, England, have invented a certain new and useful Pile Fabric, of which the following is a specification.

This invention relates to a new article of manufacture, consistingof afabric combining all the elements of, say, for instance, a sixcarpet, (although I do not confine myself to six frames, as Inore Aor less may be used with equal advantage, but I have simply described a six-frame fabric for illustrating my invention,) in which not more than three (or half the number) of the warp-threads used are at any time buried in the back or ground of the fabric, instead of five threads being buried, as is the oase with six-frame Vilton or Brussels carpets.

4warp-threads of the double fabric before it is cut apart, and Fig. 2 asection at right angles to Fig. 1.

In carrying out Iny invention two fabrics or cloths are simultaneously woven together, and are afterward divided by .any suitable cutting device on the line 0c 0c, Fig. 1.

Referring to the accompanying drawings, ct represents the warp-threads or colored yarn which form the pattern gb b2 b3 b4, the weft or shuttle shots; c, the ground-chains, and d stuffer or filling threads.

In commencing to weave the fabric let it be supposed that the warp-threads have been equally divided by the jacquard, so that the threads 1 2 3 (which, for example, may represent drab, red, and light-blue threads, respectively) are raised and the threads 4 5 6 (which may, respectively, represent dark-blue, gold, and bronze threads) lowered. With the warp-threads in this position, the weft-shots b (which may be white, for example) on the right-hand side of Fig. 1 are simultaneously thrown by two shuttles, after which the threads 1 2 3 and 4 5 G are respectively lowered and raised by the jacquard and the comber-board. The threads 1-2 3 required to form the pattern pass direct to the lay bottom, the rest of the threads, having been trapped, remaining in the center of the shed, while the threads 4 5 6 required to form the pattern rise to the top. The rest of the said threads are brought by the coInber-board to the center in the same line as those trapped from the top, and then the shots b2 (which may be white) are thrown by the shuttles. The stuffer or iilling threads CZ are then lowered in the top cloth and raised in the bottom cloth to the center of the shedding, and then the shots b3 are thrown. The threads 1 2 3 and 4 5 6 and the stuffingthreads are then returned to their former positions by the jacquard, the comber-board, and the stuffer-thread heddles, after which the shots b4 are thrown. Thus far the heddles which operate the chain c have remained unaltered; but after the shots b4 have been thrown the said chain-heddles reverse their positions, causing the chain-threads c to cross fromover to under, and vice versa, so as to bind the warp-threads and the stuffer or filling threads with the weft-shots b b2 b3 b4 above and below, as shown in Fig. 1, after which the shots b and the operations hereinbefore described are repeated until the desired length of double fabric is completed.

The fabrics maybe divided as the Weaving progresses, or afterward, if desired.

It will be seen that the stuffer or filling threads d do not pass from one fabric to the other, but lie in the ground of the fabric. It will also be seen that of the six sets of warpthreads used never more than three of them are at any time buried or woven inthe back or ground of each fabric, and when one of the sets of threads in each fabric is being Worked into the pile to form the pattern there are only two sets buried or Woven in the back or ground of each fabric, while the threads which form the pile are 'more eifectually bound in the body of the fabric by the stuffer or filling threads d and the shots h3.
