ENGRAIN CARPET FABRIC.

SPECIFICATION forming part of Letters Patent No. 656,113, dated August 14, 1900.

Application filed March 31,1899. fierial No. 711,274. (No specimens) T0 at whom it may concern:

Be it known that I, HARRY HARDWIOK, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Ingrain Carpet Fabrics, of which the following is a specification.

The object of my invention is to provide a fabric in the nature of an ingrain carpet fabric, but having extra weft-threads intro duced in certain portions of the same, so as to form figures upon the face'of the fabric, said extra weft-threads differing from the weft-threads of the body ofthe fabric in that they do not extend completely across the same from selvage to selvage, but are discontinued except in those portions of the fabric where their presence is necessary for the formation of the desired figures.

In the accompanying drawings, Figure 1 is a view of a piece of fabric made in accordance with my invention, showing upon the face a figure containing the extra weftthreads. Fig. 2 is an enlarged sectional diagram taken in the direction of the weft and illustrating the various weaves to be found in difierent portions of my improved fabric. Fig. 3 is a section, taken in the line of the warp, of the portion A of the fabric shown in Fig. 2. Fig. 4 is a similar section of the portion B of the fabric. Fig. 5 is a similar section of the portion D of the fabric. Fig. 6 is a similar section of the portion F of the fabric. Fig. 7 is a similar section of the portion G of the fabric. Fig. Sis a similar section of the portion H of the fabric, and Fig. 9 is a similar section of the portion K of the fabric.

It will be understood that'the views Figs. 2 to 9 are much exaggerated and the various warp and weft threads are separated from each other, so as to better illustrate them. Hence these views are not to be taken as exactly representing sections of the actual closely-woven fabric.

The fabric is woven with warp-threads in sets of eight, (lettered, respectively, a b c d and a- Z) c d,) with weft-threads,'either in sets of four in the body of the fabric or in sets of eight in those portionsof the fabric where the supplementary surface figures are formed,

the body-wefts being numbered, respectively, 1, 2, 3, and 4, and these wefts being combined with the additional wefts 5, 6, 7, and 8 in the figured portions.

The body of the fabric may be woven in the same manner as an ordinary two-ply ingrain carpet fabric. Thus the wefts 1 and 3 may represent the ground-wefts of an ordinary two-ply ingrain fabric, and the wefts 2 and 4 may represent the figure-wefts of such fabric, these wefts being interwoven with the warps, so as to bring either the groundwefts up or to the face of the fabric, as shown in the portion A of Fig. 2 and in Fig. 3, or the figure-wefts'up, as shown in the portion K of Fig. 2 and in Fig. 9, the wefts 1 and 3 being of the same color or of different colors and being bound by the warps a. b c d, which may be of the same color as the wefts which they bind or of a color harmonizing therewith, the wefts 2 and 4 being of the same color or of different colors and contrasting with the wefts 1 and 3, and the binding-warps a b c d for these wefts 2 and 4 being likewise similar in color thereto or of a color harmonizing therewith. The extra figuring wefts 5, 6, 7, and 8 may be of the same'or of different colors, being preferaby such as to contrast strongly with the wefts of the body of the fabric, and these extra figuring-wefts are bound by those of the warps which best harmonize in color therewith, these warps in the present instance being those lettered a b c (1.

Where the special wefts 5, 6, 7, and 8 appear upon the face of the fabric, the wefts 1, 2, 3, and at are carried to the back, as shown at F and H in Fig. 2 and in Figs. 6 and 8, either the special wefts 5 and 7appearing on the face of the fabric, as at F in Fig. 6, or the wefts 6 and 8 thus appearing, as at H in Fig. 8, in accordance with the requirements of the pattern, the unused wefts of the set going to the center of the fabric, as shown.

In these portions of the fabric the face-wefts are tied down and the back wefts are tied up to the central or buried weft-s by means of the warps a b c d, the warps a b c d floating below the face-wefts, as shown, so that of each set of eight warp-threads'two are used for tying down theface-wefts and two for tying up the back wefts, the remaining four floating between the wefts.

So far as regards the tying function the same result would be attained if the tyingwarps passed from face to face of the fabric instead of engaging with the buried wefts; but the latter construction attains another result-that is to say, the tying of the special figuring-wefts at less frequent intervals than the wefts of the body of the fabric, so that the color of the special figures is not afiected by the overlying warps to the same extent that it would beif said special figuring-wefts were tied down more frequently, it being understood that the warps which tie down the special figuring-wefts are not likely to be of the same color as said wefts, and hence the less frequently the latter are covered bysaid warps the nearer will the desired solid color effect in the figure be obtained.

Variation in the pattern and coloring of the special face-figure may be effected by carrying one of the body-wefts to the surface in the midst of such figure-as shown, for instance, at G in Fig. 2 and also in Fig. 7--the special figuring-wefts in this case passing to the back of the fabric and the other body weft being buried in the center of the fabric, the body-weft which goes to the face being preferably tied down at infrequent intervals in the same manner as the special figurewefts. It may also be desirable in some cases to surround each of the figures with a border composed of body-wefts strongly contrasting in color therewith-for instance, the wefts 2 and 4, as shown at D in Fig. 2 and also in Fig. 5. In these portions of the fabric it is preferable to weave a face-web composed of the warps a b c d and the wefts 2 and 4 and a back web composed of the special figuring-wefts 5, 6, 7, and 8 and the warps a b c d, the remaining body-wefts 1 and 3 floating between these two webs.

At the sides of each of the special face-figures it is desirable to tie the ends of the special figuring-wefts into the body of the fabric, so as to prevent the pulling of said ends through to the face of the fabric, for it should be understood that while in weaving the fabric the special figuring-wefts float on the back of the fabric from figure to figure these floating wefts are subsequently cut off, and if it were not for this tying up of their loose ends on the back of the fabric the desired integrity of the fabric would not be attained. The character of the weave in these portions of the fabric is represented at B in Fig. 2 and in Fig. 4, the face-wefts being tied down to the buried weft by the warps a b and the back wefts being tied up to said buried weft by the warps c at.

My improved fabric may be said to have a two-ply weave in the body portion and a modified form of three-ply weave in the figured portions, but this three-ply weave is confined to said figure portions and does not extend across the fabric from selvage to selvage.

Having thus described my invention, I claim and desire to secure byLetters Patent 1. A carpet fabric having a body composed of interwoven warps and wefts and surface figures composed of special wefts overlying the body-wefts and tied down by certain of the warps, each of said special figuring-wefts being independent of and disconnected from the others, and discontinued from figure to figure across the back of the fabric.

2. A carpet fabric having a body composed of interwoven warps and wefts and surface figures composed of special wefts and tied down by certain of the warps, said special face-wefts being also united to the body of the fabric on the back of the same for a short distance beyond the figures but being otherwise discontinued from figure to figure across the back of the fabric, substantially as specified.

3. A carpet fabric having a body composed of interwoven warps and wefts and surface figures composed of special wefts overlying the body-wefts, and tied down by certain of the warps, there being, adjacent to the edges of said face-figures, fabric composed of one of the body-wefts and certain of the warps interwoven to form an upper ply, and said special face-wefts and the other warps interwoven to form a back ply, the other bodywefts floating between the two plies and the special face-wefts being tied up to the body of the fabric by certain of the warps beyond such plicated portions, substantially as specified.

4. A carpet fabric in which both the warps and wefts are disposed in sets of eight, said warps and four of the wefts being interwoven to form the body of the fabric, and the remaining four wefts being introduced only at intervals and throughout portions of the width of the fabric to form special surface figures, such figured portions being tied by four of the warps of each set, the remaining four warps of each set floating behind the facewefts throughout the extent of such figures, substantially as specified.

5. A carpet fabric having a body composed of interwoven warps and wefts forming a twoply fabric and having special wefts extending throughout only a portion of the width of the fabric and overlying the body-wefts so as to form figures on the face of the fabric, said figured portions forming a three-ply fabric, substantially as specified.

6. A carpet fabric having a body composed of interwoven warps and wefts forming a twoply fabric and having special wefts extending throughout only a portion of the width of the fabric and overlying the body-wefts so as to form figures on the face of the fabric, said figured portions forming a three-ply fabric in which the face-ply is bound down and the back ply is bound up by warps engaging with the embedded intermediate ply, substantially as specified.
