To all whom it may concern: i

' parts.

This invention relates to woven fabrics and has for its object to provide a novel woven fabric which is .so constructed that the two opposite faces thereof are formed from separate threads, the threads which constitute each face appearing only on said face. A fabric of this nature can be woven so that the threads on one face will be of a different material or color from those on the other face. Thus itis possible to weave a fabric embodying my invention in which the threads on one face are cotton threads and those on the other face are woolen or silk threads. Y

A fabric embodying my invention is admirably adapted for various uses, such, for.

instance, as automobile tops, shoe tops, airplane fabric, pneumatic tire'fabric, etc.

In constructing my improved. fabric I (aim ploy three sets of warp threads, the warp threads of one set appearing only on and constituting one face of the fabric, the Warp threads of another set appearing only on and constituting the other face of the fabric, and the warp threads of the third set being situated intermediate of the first two sets of warp threads and extending centrally of the fabric. The warp threads of the first two sets, Which I will refer to as face-forming warp threads, are bound to the central or intermediate warp threads by the filling" threads? With this arrangement of warp and filling threads each. face of the fabric may be given a distinctive characteristic according to the character of the face-forming warp threads which constitute said face of the fabric.

in order to give an understanding of the invention, I have illustrated in the drawings a selected embodiment thereof which will now be described, after which the novel.

. features willbe pointed out in the appended claims.

in the drawings, Figure 1 1s a longitude nal sectional view through a fabric embodying my invention, said view being exaggerated somewhat in order to better illustrate the construction;

Fig. 2 is the design draft for the weave on a single-pick loom;

Fig. 3 is the design draft for the weave on a two-pick loom; v n

Fig. 4 is the design draft for the weave on a four-pick loom Fig. 5 isa section on the line 5-5, Fig. 1; Fig. 6 is a perspective diagrammatic view showing the manner in which the warp and filling threads are interwoven, thethreads in said figure being Widely separated in order to ,more \clearly illustrate the weave.

In the design drafts the blanks indicate warp threads down; the dots indicate Warp threads raised; the crosses indicate warp threads half raised; the rings with dots therein indicate warp threads raised threequarters of the warp shed, and the rings with crosses in indicate warp threads dropped three-quarters of the distance of the warp shed.

The Warp threadswhich form one face of the fabric are" indicated at a, b, c, d, thosewhich form the other face of the fabric are indicated at c, f, g, h, and the center or intermlodii ate Warp threads are indicated at Z: .7 s

In the illustrated fabric, the warp threads are shown as interwoven with the filling threads as a three-to-one twill and hence the Warp threads will be insets of four. The filling threads are also arranged in sets of four, the filling threads of ,eac-hset being situated substantially one above the other transversely of the fabric.

Each face-forming warp thread is floated over three sets of filling threads and then is passed around three filling threads of the next set, and, as stated above, in illustrated embodiment of the invention, the warp threads are interwoven to'form athree-to-f one twill. With this construction it will take sixteen picks offilling threads to complete the weave, the filling threads being in dicated bythe numerals i to 16. The filling threads designated 1, 2,.3, 4 constitute the first set, those designated 5, 6, 7 and '8 constitute the second. set; those designated 9,

10, i1, 12 constitute the third set, and those designated 13, 1; 15, 1G constitute the fourth set; These four sets of, filling threads are repeated throughout the fabric.

threads of the next set 5, 6, 7, 8, and then are floated over the next three sets of filling threads.

The warp threads 0 are floated over the first two sets of filling threads 1, 2, 3,.aand

5, 6, 7, 8, and then are carried under the three filling threads 9, 10, 11 of thc third set, and thence over the filling threads of the fourth and next two succeeding sets, etc.

The warp threads cl are carried OVQI the first three sets of filling threads, then under the filling threads 13, l-i-t and 15 of the fourth set, and then are floated over three sets, etc.

The warp threads 6, f, 9, it are similarly interwoven, that is, each warp thread is floated under three sets of filling threads and then is carried. over three filling threads of the next set. For instance, the warp thread 9 passes over the three filling threads 2, 3, 4: of the first set, and'then floats under the next three sets of filling threads, and then is carried over the three filling threads of the fifth set, etc. The warp thread it is carried over the three lower filling threads 6, 7 and 8 of the second set and under all the other sets of filling threads. The warp.

thread 6 is carried over the three filling threads 10, 11 and 12 of the third set and under all the other sets of filling threads, and the warp thread I is carried over the three filling threads 14, 15, 16 of the fourth set and under all the other 'setsof filling threads.

The intermediate set of we threads i, 7',

7c, Z extend substantially straight between 'the'center filling threads of each set and thus each of the face-forming warp threads is bound to the center or intermediate warp threads by the intermediate filling threads.

Since each face-forming warp thread passes under or over only'three filling threads of each set, it follows that it will appear only on one face of the fabric. vFor instance, the loops in the warp threads at which pass around the three filling threads of the first sets are covered by the filling threads 4, the

, loops in the warp threads 6 formed by passing under the three filling threads 5, 6 and 7 are covered by the filling thread 8. The similar loop in the warp thread 0 where it passes under the filling threads 9,10 and 11 is covered by the filling thread 12, and the loop in the warp thread (i caused by passcovered by the filling thread 16. Similarly,

the filling threads 1, 5, 9 and 13 cover the loops formed in the warp threads 6, f, g, A where they pass over the three filling threads of any set. Hence the filling threads 4, 8, 12 and 16 prevent the warp threads a, b, c, d from bein exposed or showing on the under side of the fabric and the filling threads 1, 5, '9' and 13 prevent the face-fonning warp threads 6, f, g, h from showing on the upper face of the fabric. Hence the character of the upper face of the'fabric is determined by the character of the warp threads a, 6,0, cl and as not affected at all by the character of the warp threads e, f, g, it. Similarly, the character of the lower face of the fabric is determined solely by the character of the warp threads 6, f, g, in If, for instance, the face-forming Warp threads or, b, 0, (Z and the filling threads in the upper half ofthe fabric are of wool and the, face-forming threads 6, f, g, 72, and the filling threads in the lower half of the fabricare made of cotton, a fabric is produced, one face of which is woolen and the other face of which is cotton. A fabric of this nature will be practically waterproof and yet the woolen face thereof would be capable of taking and holding color, thus producing a fabric, one face of which has a rich and lasting color. A fabric of this construction has special advantages when used as shoe cloth tops or for automobile tops, and is also capable of use for various'other purposes where it is desired to use a cloth in which the two faces present different characteristics.

The cloth herein illustrated may be woven on a single-pick looni or on a double-pick" loom, or on a four-pick loom. When woven.

on a single-pick loom, it will take sixteen picks to complete the weave since only one shot of filling is inserted at each pick. When a sing1e-pick loom is used the warp threads will be raised and lowered for the individual picks, as indicated in the chart shown in F 1g. 2 wherein blank spaces indiwarp threads u Where a doub e-pick loom is used in which cate warp threads down and dots indicate two shots of filling are inserted at each pick,

then the weave can be completed in eight picks and the manipulation of the warp threads during the succeeding picks is illustrated in the chart shown inFig. 3 wherein. blank spaces indicate warp threads down, dots indicate warp threads up and crosses indicate warp threads half raised. In weaving the fabric in accordance with the chart shown in Fig. 3 on the first pick weft threads 2 and.3 will beinserted; on the secondpick'weft threads 1 and 4 will be inserted; on the third pick weft threads 6 -and 7 will be inserted; on the fourth pick weft threads 5 and 8 will be inserted, and

' at each pick, and in this case the warp threads will be manipulated in accordance with the chart shown in Fig. 4 wherein blank spaces indicate warp. threads down,

to-one satin, or the intermediate warp threads can be. interwoven instead of lying in a straight line.

I claim: 1 1. A woven fabric having two sets of faceforming warp threads and a set of intermediate warp threads and 'having filling threads arranged in sets of four, each faceforming warp thread being floated over a 1 plurality of adjacent sets of filling threads and then being interwoven with the intermediate war threads by some of the filling threads of t e next set, each face-formin dots indicate warp threads ralsed, crosses indicate warp threads half raised, rings with crosses therein indicate warp threads warp thread appearing only on one face 0 the fabric.

2; Awoven fabric having two sets of faceforming warp threads and filling threads arranged in sets of. four, each warp thread being floated over a plurality of adjacent sets of filling threads and then passing under three .fillingthreads of the next set whereby the face-forming warp threads of eachv set appear only on one face of the fabric. r

In testimony whereof I aflix my signature in the presence of two attesting witnesses.
