3 Claims. (01. 139-403)- The present invention relates to textile pile fabrics and more particularly to textile struc--' tures adaptable for rug and carpet manufacture.

The principal object of this invention is to provide a novel and improved pile fabric having a through-to-the-back bind, affording a strong textile structure for the rug and carpet manufacturing art.

In the accompanying drawings forming part of this specification, similar characters of reference indicate corresponding parts in all the views.

Fig.. 1 is a diagrammatic warpwise view showing the weave structure effected in alternate courses of the fabric in accordance with the teachings of this invention.

Fig. 2 is a similar view showing the weave structure made in the intermediate courses of said fabric.

Fig. 3 is a similar view showing the composite weave in adjacent courses of the fabric.

Fig. 4 is a diagrammatic weftwise view of the said fabric. The courses are here indicated.

Fig. 5 shows a top view of the pile fabric made pursuant to this invention.

In the drawings, in each warp course of the fabric illustrated, there are warp stuffer, one .pile yarn and a pair of warp yarns to form the binding chain. The alternate courses are marked A and the courses intermediate these are indicated as B. In the courses A, the warp stuffer yarns are denoted by the numeral 25, the pile yarn is indicated by the numeral 26 and the chain yarns are designated respectively In the courses B, the stufier yarns are indicated by the numeral 35, the pile yarn is 36 and the chain yarns are 31 and 3'! respectively. A web 30 is formed of the stuffer yarns 25, 35, incorporating what shall be called the upper wefts indicated by the odd numerals from to ll, to make such web. Intermediate each two upper wefts and below the web 30, but above the pile yarns 26, 36, there is positioned a weft. These wefts, herein called the lower wefts are denoted by the even numbers 2 to I8. The binding yarns 21, 21, and 31, 31', form chain engaging the upper sides of the upper wefts and the undersides of the lower wefts in a manner to be described. Loops 29, 29', 29", 29" are raised in each pile warp 26 to extend through the web 30 and above its upper surface. Loops 39, 39', 39", 39' are likewise raised from the pile warps 36. The position of said pile loops with respect to each other and their relation with. the other components, will be described.

. loops respectively,

vIn the web 3ll,'the stuffer yarns 25 are over alternate upper wefts and under the other upper wefts, while the stuffer yarns 35 are under those upper wefts the yarns 25 are over, and over those upper weftsl't'he -said yarns 25 are under.

Each of the pile loops. ofthe series 29 and 39, have through them .two adjacent upper wefts and also the lower weft which is intermediate such pair of upper wefts. .For instance, the pile loop 29 in Fig.

and 1. 1 I

In each pile yarn, two successive loops have through them respectively, successive pairs of upper wefts and one lower weft respectively; the lower wefts thus associated withtwo' successive are in alternate relation among the lower wefts. The lower weft intermediate such two lower wefts, is above such pile yarn, between saidsucce'ssive loops. For instance, the two successive loops 29' and 29" in Fig. 1, have through them the wefts 5, 6 and I through one, and 9, l0 and I l through the other, while weft 8 is above the pile yarn 26, between such successive pile loops.

In one direction warpwise, one chain yarn in each of the courses, is under all lower wefts which are between successive loops in the pile yarn in the course of the chain yarn dealt with, and over all those upper wefts first nearest to said lower wefts which are between the successive loops. In the same direction warpwise, the second chain yarn in each course, is under all the lower wefts lying through the loops in said pile yarn in its course, and over the other upper wefts which are through said loops. For instance, in the direction from left to right in Fig. '1, the chain yarn 21 is under the lower wefts 4. 8, iii, and over the upper wefts 5, 9, It. In the same direction, the associated chain yarn 21' is under the lower wefts 2, 6, I0, and over the upper wefts 3, 1, II.

The loops in adjacent courses are in staggered overlapping relation because the lower wefts which are through the loops in alternate courses, are those which are between the loops in the remaining courses. For instance, the lower wefts 2, 6, H), which are through the pile loops of the series 29, are between successive pile loops of the series 39.

In each course A and B, the loops raised from the pile yarn therealong, are preferably between the stuifer warp and the chain yarn in the course. The pile yarns ma} all be of one color, or of different colors as may be desired. .Also, the loops may be cut as is known in the art.

The pertinent advantage of the construction 1, has through it the wefts 5, 6

in pile fabrics herein set forth, is that pile yarn goes under the lower weft, locking same in place and thereby effecting a strung bind, and a very sturdy structure is gained by the included web 38 formedvofi theustufler interwoven with the 5 upper wefti'i.

Having described the structure of my new and improved pile fabrics, I desire that the following, be protected by Letters Patent, and therefore, claim:
