DOUBLE PILE FABRIC Filed April 13, 1928 )m m m March 3, 193].

latentecl Mar. 3, 1931" UNITED STATES PATENT OFFICE DOUBLE-PILE FABRIC Application mea April 13, 192s. serial no. 269,619.

My invention relates to double pile fabrics, that is to say, to fabrics which are woven with two ground weaves, and having pile forming vwarps extending therebetween which are subsequently cut for the purpose ofproducing two separate fabrics, each having a pile face.

In my previous application for Letters Patent, filed March 27, 1928, Serial No.

1o 265,130, there is shown and described a fabric of the type aforesaid, which may be woven in a double shuttle loom. My present invention contemplates a fabric which is in some respects similar to the fabric there shown,

but which, however, is more particularly adapted to be woven in a loom in which but one shuttle is thrown at each pick, and in which fabric there will be amore substantial body of pile.

The principal object of my present invention is to provide an improved double pile fabric which, when cut apart, will produce two rugs or carpets, each of the well known Tilton type. i

A further object of my invention is to provide a fabric of the type aforesaid, in which the pile "tufts will be securely held in the ground weaves after the same are cut apart. i

Y A further object of my invention is to provide a fabric of the type aforesaid in which therenwill be a substantial body of pile in the face thereof.

A further obj ect of my invention is to provide a fabric of the type aforesaid, in which the dead ends of the figuring warp will be evenly distributed in the ground weaves,

whereby the same willbe of a uniform texture, and this notwithstanding that a certain 40 color or colors may predominate in the pile.

A further object of my invention is to provide a fabric of the type aforesaid, whereby seamless Wilton rugs of the larger or room sizes, may be more economically produced than heretofore.

With 'the foregoing objects in view, my invention contemplates the provision in a double pile fabric of similar upper and lower ground weaves each having a pluralit of shots `of weft between each crossing o the binder warp, the carrying of the pile forming warp from the one ground weave to the other to form the pile, and the binding of the pile warp in the ground weaves in such manner that the same will be securely held therein.

The nature and characteristic features of my invention will be more readily understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which:

Figure l is a longitudinal section of a double pile fabric embodying the main features of myinvention, illustrating the arrangemeit therein of one set of figuring warps; an

Figure 2 is a similar View, illustrating the arrangement of an adjacent set of figuring warps. y

Referring to the drawings, in the particular embodiment of my invention therein shown, the double pile fabric comprises two similar ground weaves, the upper ground weave` consisting of pairs of binder warp l and 2, and three shots of weft 3, 4 and 5, respectively, between each crossing of the binder warp thereof, and the lower ground weave also consisting of pairs of binder warp 6 and, and three shots of weft 8, 9` and l0, respectively, between each crossing of the binder warp thereof.

It will be noted, however, that the crossing of the binder warp of the lower ground weave preferably takes place between the crossing of the binder warp of the upper ground weave.

It should also be noted that the weft shots 3 `lie in the outer plane of the upper ground Weave, and the weft shots 4 and 5 liein the inner plane thereof, and in like manner the weft shots 8 lie in the outer plane of the 90 lower ground weave, and the weft shots 9 and lie in the inner plane thereof.

For the purpose offorming the pile, the figuring warps are carried from the one ground weave to the other, and back again. In the drawings, there is illustrated a typical arrangement of the figuring warps wherein the same are arranged in groups or sets of color ends, and in one group or set (sce Fig. 1) there are three different colored figuring warps 11, 12, and 13, which are primarily carried by the upper ground weave, and three other differently colored figuring wa- rps 14, and 16, which are primarily carried bythe lower ground weave. This arrangement will ordinarily be provided in a single'dent space:

of the loom in which the fabric is woven.

In the next adjacent group or set. of color ends, (see Fig. 2) the corresponding figuringy warps of the colors 11,-12, and 13 are primarily carriedbythe lower ground weave, and the-three figuring warps of the colors 14, 15'and 16in that group are primarily carried by the upper ground weav Y VKVhenla figuring warp is to form the pile, thesame passes into` the pile region from between the inner' and outer planes of the ground weave where it` has been carriedas a deadend. 4 y.

At the left hand endof each figure ofthe drawings, the warp 13 is shown as making the pile, and in Fig.y 1 the same is shown as passing from the `upper ground weave, where it is :primarily carried, passing between the wefts numbered 4 and 5 of a particular shedding of the binder warp Vof that ground weave, thence over to the other ground weave, where it passes between the wefts numbered 9 and 10 of a particularshedding of that ground weave, thence between the inner and outer planes of the wefts of that ground weave, thence'returning to the original ground weave from which it was taken, passing between the wefts numbered 9 and 10 of the next -shedding ofthe lower ground weave and between the wefts numbered 4 and 5 of the same shedding ofthe upper groundv weave from. which it emerged, and repeating in like manner as long as the particular color is' required in the face In like-manner, in the adjacent group or set of figuring warps (see Fig. 2),v the-warp 13 which in that group v1s primarily carried in the lower ground weave, passes between the wefts numbered 9 andlOof a particular Vshedding of the binder warp thereof, thence over to ythe upper ground weave, where it passes between the wefts numbered of and 5 lof a particular shedding of the binder warp .l of theupper ground weave, and between the namely, 11, 111, 15 and 16, are

wefts numbered 9 and 10 of the same shedding of the lower ground Weave from which it emerged. Y

When the color changes, the warp which has been used in the pile forming as aforesaid is thereafter carried as a dead end between the inner and out-er planes of the weft of thel ground fabric, and another color is brought out and in like manner carried across from the one ground fabric to the other and back again, so that the same will then appear in the face of the pile.

While, in the drawings, the warp ends 12 and 13 are the only ones illustrated as being carried over from one ground weave to the other and back again, itwill, of course, be understood that the other figuring warps, in like manner carried over lwhenever their respective colors are used in the pile.

lt should be noted, however, that fory the best results the figuringl warp which has been carried over to form the pilewill be finally returned to the ground weave from which it came, and is thereafter carried in said ground weave as a dead end, and in this manner the distribution of the yarn between the two ground weaves will be balanced and the texture be kept even throughout.

It will, of course, be understood that the number of pile forming Vwarps carried by the respective upper and lower ground weaves will be considerably varied in practice, according to the requirements of the pattern, etc.

' It will also be apparent that, if desired, stuffer warps may be used in addition to the figuring warps, for the purpose of giving ad ditional body to the ground weaves. It has not been thought necessaryv to illustratesuch stuffer-warps as the same are not essential to the weave. v Y

t will be seen that by thep-resent invention there is provided a fabric of the double pilel type, adapted to be cut apart in the usual manner for the purpose of formingtwo Wilton carpets or theY like, which when so cut apart will produce two carpets which .will be equally desirable and ofuniform texture and Y weight throughout, in 'which' thepile tufts will besecurely bound in the ground weave,

.Y in which there will be a substantial body of pile in the face thereof, and which may be woven in widths for the production of the larger or room size seamless rugs.
