INGRAIN CARPET FABRIC.

SPECIFICATION forming part of Reissued Letters Patent N 0. 11,955, dated fiecemberI-O, 1901. Original No. 673,503; ama May 7.19m. Application fo reissue filed October 28, 1901. Serial No. 80,337.

To all whom it may concern.-

Be it known that I, WILLIAM B. KEEFER, a-citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Ingrain Carpet Fabrics, of which the following is a specification.

My invention has relation to a woven-substantially one-plane ingrain carpet fabric, and in such connection it relates to the arrangement of the figuring and binding warpthreads with relation to the figuring and bindingweft-threads in the fabrici The principal object of my invention is to produce a substantially one-plane ingrain carpet fabric having two acceptable faces adapted to be alternately ornamented by additional figuring warp-threads and-to have.

the solidity and apparent thickness of the ordinary two-.planeingrain carpet, but costing much less to produce.

My invention consists of a'substantially one-plane iugrain carpet fabric having the main weft-threads bound separately in sheds by two binding warp-threads and having two acceptable faces, each alternate shed containing in addition to the main weft-threads a binding or a combined binding and figuring weft-thread and both faces of the fabric being alternately ornamented by figuring-warpthreads united to the face which they are designed toornament by the additional binding or combined binding and figuring weft threads.

The nature and scope of my inventionwill be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in which- Figure 1 is a longitudinal sectional view of a portion of a fabric embodying main features of my invention. Figs. 2 and 3 are views similar to Fig. 1, but illustrating other effects in the fabric;and Fig. 4 is a view simi-' lar to Figs. 1, 2, and 3, but illustrating a modified form of fabric.

Referring to Figs. 1, 2, and 3 ofthe drawiugs,the main weft-threads a are separately arranged in sheds and bound by the com parativelythin binder warp-threads 1 and 2. Each alternateshed contains,in addition to the main faces of the fabric thus formed are equally acceptable and are ornamented by figuring warp-threads 3 and 4; trated in the drawings these figuring warpthreads 3 and.4 are black, although it is obvious that they may, if'desired, be colored,

weft-thread a, a binder weft-thread b. The

In the fabric illustraverse the weft-threads a and to ornament the lower face of thefabric, the figure or pattern extending under six weft-threads a. It

is obvious, howev er, that'the extent of the figure or pattern can be varied at will, providing the figuring warp-threads are properly tied to the surface which they are to ornament. Thus in Figs 2 and 3 the two warpthreads .3 and 4 appear in alternate sheds upon the rear and face ofthe fabric, and hence fioat either under or over one-weftthread a. 0 thus tie the-figuring warpthreads, the binder weft-threads b are introdueed -into alternate sheds, and in the preferred manner of binding or tyi'ng (illus trated in Fig. 1) the warp-threads 3 first pass over a weft-thread a, then under a binder b in the next shed, then over the remaining two wefts a in the first set or weave containin g six picks-namely, four of wefta and two of binder b. The warp-threads 4, however, in this set or Weave first pass over four wefts a and the first binder b and under the second binder b. It will thus be seen that one warpthread 3 is bound to the surface by the first binder I), while the Warp-thread 4 is bound by the second binder b of the series. In the next set or weave thetwo warp-threads 3 and 4 both pass over the first two wefts a and then traverse the fabric and pass under the final two wefts a to ornament the back of the fabric. In thisset the thread 3 pa sses under the first binder b of the set and above the second binder of said set, whereas the thread 4 passes over the first and under the second binder'in In the third set the course of threads said set.

Ice

3-and 4 is the reverse of the course taken by the threads 3 and 4 in the first set (illustrated in Fig. 1)that is to say, both threads 3 and 4 pass under all ofthe wefts a, the thread 3 being bound by the second binder in the set,

whereas the thread 4 is bound by the first binder: in said set. In the completed fabric the figuring warp-threads 3 and 4 will both .be tied by a corresponding number of binder weft-threads b.- When both warp-threads 3 and 4 are to float'under .and over a single weft-thread a, as in Figs. 2 and 3, the binder weft-thread b is inclosed between the two warp-threads 3 and 4, and one of said warpthreads 3 or 4 1's -inclosed between 'a binder weft-thread b and a weft-thread ct.

In Fig, 4 a similar arrangement of the fabric hereinbefore: described is illustrated, the

main changes or modifications consisting in replacing the binder weft-threads b of Figs.

'1, 2, and 3 by a series of combined binding and figuring weft-threads Z). and in manipulating' said weft-threads b in conjunction with the warp threads 3 and 4 to produce other coloring or figuring effects notv possible in the fabric illustrated in Figs: 1, 2, and 3.

In allthe'figuresthe main weft-threads a are colored olive, white, green, and red, ac-

- cording to the key-chart. In Fig. 4 the binder weft-threads b are ill nstrated as colored white and red. These wef ts a and b" may, however, be of any other colors, as desired.

Having thus described the nature and object of my invention, whatI claim as new, and desire to secure by Letters Patent, is-

1. A substantially one-planeingrain carpet fabric having two acceptable faces, a series of main weft-threads bound separately into sheds by two binder warp-threads, an additional wef trthiread included in altern ate sheds,

and figuring warp-threads adapted to ornament the faces of the fabric and to be bound to said faces by the additional weft-threads;

2. Asubstan tiallyone-plane ingrain carpet fabric having two acceptable faces, a series of main weft-threads bound separately into sheds by two binder warp-threads, an additional figuring weft-thread included in alternate sheds, and figuring warp-threads adapted to ornament the faces of the fabric and to bebound to said faces by the additional uring weft-threads.

In testimony whereof I have hereunto-set my signaturein the presence of two su'bscribing witnesses.
