To all whom it may eomem:

Be it known that I, VICTOR H. J mmmes, a subject of Great Britain, residing at Worcester, in the county of Worcester, State of Massachusetts, have invented a certain new and useful Improvement in Woven Fabrics, of which the following is a specification, reference being had therein to the accompanyin drawings.

he invention is an improvement in fabrics or webs of that kind which are woven of one width in one portion of the length thereof, and of a different width in a succeeding ortion, examples of such fabrics or webs ing shownand described in United States Letters Patent N 0. 859,067, granted under date of July 2, 1907.

The main object of the invention is to add to the thickness of the broad portion of a fabric or web of the said kind, or give increased body, and also to give added strength. v

. The invention consists, accordingl in a fabric or webbing having portions of dlfierent widths as aforesaid, and provided with a longitudinal thickening or reinforce woven integral therewith, as will be explained with re erence to the drawings.

The invention is of particular value in the case of a'web or fabnc in-which the wa threads all extend continuously throughout the length, and the narrow and broad portions both contain the same number of threads. In such case, the broad'web-portion ordinarily has less thickness and substance than the narrow web-portion.

Figure 1 of the latter shows a view of one face of a short piece of fabric of two widths. Fig. 2 is a view of the other face of such fabric and shows a longitudinal thickening or reinforce such as has just been referred to. 3 is a dia ram illustrative of one manner of carrying 51c invention into effect, and shows the difierent portions of the broad part of the fabric in the relative ositions which the occupy in the loom in being woven. ig. 4 is a diagram showing the fabric-section of Fig. 3 opened out flat, as in its final state subse uent to removal from the loom. Fig. 5 is a diagram similar to Fig. 3, but showing a supplemental layer or ply that is bound to the main web at additional points in the width thereof. Fig. 6 is a dia ram like Fig. 4, but showing the fabric of ig. 5

I opened out flat.

Fig. 7 is a diagram similar in character to Figs. 3 and 5 but showing an embodimentof the invention in which the margins of the band of thickening are interwoven solidl with the adjacent portions of the web or abric. Fig. 8 shows the fabric of Fig. 7, opened out flat.

Figs. 1 and 2 the narrow portion or width of the web or fabric is marked A, and the broad portion is marked B. As in the Letters Patent aforesaid, the same warpthreads are continuous throughout the web or fabric, and the same number of threads is contained in both widths. portion or width A, the said warp-threads are interwoven with the weft or filllng in approvedmanner' into a (plurality of layers or lies, which are joine or closed together. Tn the broad portion certain of the warpthreads are woven into distinct wings or plies, A, A, Fig. 1, which are unconnected with each other but respectively connected or joined in the weaving with the remaining portion of the web or fabric at o posite sides of the middle of the width 0 the latter. These wings or plies when spread out flat give the increased width to the portion B. -igs. 1 and 2 show the demarcation between the narrow and broad portions, and illustrate the taper where the free edges of the webs or plies are spread obliquely across the face of the web or fabric.

fabric is shown at C, Fig. 2, in the form of a band of the same width as the narrow portion A of the web or fabric, extending along the middle of the width of the broad portion B in continuation of the said narrow portion.

The character and weave of the web or fabric A, B, and of the additionahlayer or thickness at C, and the manner of reducing and combining the latter with the Email portion B in the weaving, may be varied indifferent respects. Fig. 4 is a diagram of an instance in which it is practically a distinct and separate. cloth or web, connected with the ortion B only along the middle line at a. ig. '3 is a diagram of the mode of weaving, according to which the fabric-is produced in the loom in four layers or plies, the two uppermost constituting the wings which are designed to furnish the increase of the width of the broad web-portion B over narrow web-portion A, the third layer or ply The addition to the thickness of the broad portion of the web or constituting the middle portion of the width of broad web-portion B, and the fourth layer or ply constituting the additional layer or thickness. In weaving the web or fa rie of Figs. 3 and 4, the first pick of weft or filling is interwoven from le t to right with the warp-threads of the uppermost layer or ply;

the second pick is interwoven from right to left in the same ply, completing the latter. The third right with t 1e warp-threads of the left-hand half of the width of the third layer or ply, and then passes into the fourth ply and interweaves with the warp-threads of the righthand half of the latter. The fourth pick interweaves from ri ht to left withthe warlpthreads of the fourt ply, entirel across t width of the said ply. The fift ply interweaves from left to right with the warpthreads of the left-hand half of the fourth ply, completin the latter, and then passing mto the third ly interweaves with the righthand half of t e warp-threads'thereof. The sixth pick interweaves from right to left with the warp-threads'of the second ly, and the seventh pick interweaves from eft' to right therewith, completing the said second ply. Finally, the eighth pick interweaves with the warp-threads of the third ply from right to left, com let-ing the said ply andfinishing the round. lhe diagram of ig. 4 represents the first ancM second plies spread apart and flattened o ut. The passage of pick 3 of the weft or filling from the third ply to the fourth, and of pick 5 from the fourth ply to the third, unites the said fourth ply to the main.

portion of the web or fabric at the point a, which is located at the middle of the width of the web or fabric. Consequently, the fourth ply, although presenting the appearance of a separate strap lying against the main web or fabric, in continuation of the narrow web-portion A, is integrally joined to the said main web-portion along the middle line of the broad ortion of the fabric or web, and cannotv be etached therefrom except by cutting the connecting threads.

Figs. 5 and 6 show diagrams similar to those of Figs. 3 and 4, but according to which the fourth ply (constituting the sup plemental layer) is boundito the third ply at additional )oints in the width, namely at b and c as well as at mint (1. Thus, the fourth pick of weft or ing is, in Figs. 5 and 6, caught by the second warp-thread at the right-hand side of the third ply, and also is cau ht by the second war -thread at the left hand side of such ply. he result is that the supplemental layer is also tied to the main web along lines close to the opposite edges of such layer, so that the margins of the latter, while formed as finished selvages, are distinct and not bound closely to the surface of the mainweb.

In the diagrams of Figs. 7 and 8 the weave ick interweaves from left to' is different in certain respects from that of Figs. 3 and 4. The first and second )icks of weft or filling are interwoven in t e first ly as in Figs. 3 and 4, completing such ply. lhe third right with t e v warp-threads of the fourth or reinforcing ply, being caught at the middle point (I by one of the warp-threads of the third ply, and the fourth pick interweaves from right to left with the warp-threads of the third ply. The fifth pick interweaves from left .to right with the warp-threads of the fourth or reinforcing ply, completing such ply, the said pick being caught at the oint 0 around the second warp-thread at the eft of the third ply, and also at the point around the second warp-thread at the right. The sixth and seventh picks are interwoven with the warp-threads of the second plyas in Figs. 3 and 4,fcompleting such ply, and the eig th pick is interwoven from right to left w1th the warp-threads of the third ply, comleting such ply and finishing the round. he result produced by the weave shown in Figs. 7 and 8 is that the fourth ply is interwoven at its side margins with the remainder of the web, as well as at the middle, so that the, said margins are rounded and bound solidly to the adjoining web-portions.

Fabrics. embodying the invention are of particular value for use in the manufacture of belts and the like, and of shoulder-straps, as, for instance, those which form parts of suspenders, notably those used as a part of military equipments.

What is claimed as the invention is 1. An inelastic fabric or web woven with narrow and broad ortions and with a lonitudinal inextensilile thickening or reinorcement integral with the broad portion.

2. An inelastic fabric or web woven with narrow and broad portions and with an integral inextensible supplemental or thickening layer extending longitudinally of the broad portion.

3. An elastic fabric or web woven in narrow and broad portions and with an inextensible thickening or reinforcement integral with the broad portion and in continuation of the narrow-portion.

4. An inelastic fabric or web woven in narrow and broad portions containing the same number of warp-threads, and with a portion of such warp-threads formed into a longitudinal inextensible thickening extending lengthwise of the broad portion.

5. A fabric or web having a narrow portion in which the warp-threads are interwoven into a lurality of layers or plies bound or closer? together, and a broad portion in whichcertain of such warp-threads are interwoven into one or more lateral webortions affording the increased width, and
