`Be it known that I, GEORGE C. MOORE', a citizen of the United States, residing at Revere, in the county of Essex, State of Massachusetts, have invented a certain new and useful Improvement in Woven Fabrics, ofI

which the following isi a specification, reference being had therein to the accompanying drawing. l

My invention has for its object an improvement in woven fabrics, and especially in that class of woven fabrics which are known as double-faced fabrics.

The invention will be fully understood from the following description, taken in connection with the accompanying drawing, and the novel features thereof arevpointed out and clearly defined in the claims at the close of this specification.

The accompanying drawing is a conventional 'ligure .or diagram illustrative of the construction of my improved fabric.

Although my invention fabrics of any special width, I have thus far embodied it in fabrics which are generally termed narrow fabrics, such as are made A fabric embodyingI my invention comprises two or 'three sections, which may be varied in relative widths, as desired-that is to say, the web has, ordinarily, a central and two side sections, said centralseetion being interlocked with and serving to imite the said side sections. One of the side sections may,however,be omitted. I willdescribe my invention as embodied in a fabric formed in three sections.

A single shuttle is required, and this shuttlel carries the weft-supply for the central section of the fabric. The weft for the side sections comes from two independent supone for each side section. The shuttle traverses the entire width of the web, the shuttle-thread being carried around the thread from the independent source of supply, which provides the weft for each'side section. Atveach flight of the 'shuttle1 the weftsupply for one of the side inwardly by the shuttlethread to a- `redetermined point in the width of lthe abric, covering either face of the fabric, as desired.

This pointm'ay be determined by means of a warp-thread or a wire, if a wire be employed, as is common in weaving narrow' rics and the like-that isvto say, the loom is arranged inthe well-known manner, so that the shuttle-thread will encircle or lock with 'is not limited to sections is drawn A fabi i above set forth 'body section j'of the diagram Aan outside source of weft-suiipljyv e a a. given 'warp or a wire at a predetermined point in the width of the fabric, and the loop which forms the weft or filling for the sidebe drawn inwardly by the sections will not shuttle-thread beyond this warp or wire. Inthis way, as will be clear, if the side section of the fabric is of a dierent tral section a pattern may be formed-that is, the inner edge of the side or colored section may-,be given any desired shape or contour. As the central section the weft of which is supplied from the shuttle may be relatively narrow, may be woven from one shuttle-supply, and since the weft-supply of the side sections is an independent suppl which may come from a large cop or ba l a large amount of fabric may be Woven without stoppage or delay for a new supply of thread.

To make the construction of myfabric as more clear, accompanying drawing, which represents a diagram illustrative of the construction of a s ecified kind of fabric embodying my inventionnamel fabric. In t e production of this fabric four wires are employed in the well-known manner. These are designated a,f),c, and d. The rubber warp-threads, of which there are fifteen in the particular fabric intended to be illustrated, are designated' The fibrous warp-threads, four in number, which are lin'- color from the cena large quantity of fabric what is known as an elastic I will refer to the A terinediate the rubber threads, are designated The three sections widthwise of the fabric, each of which sections is formed by a different weft-thread, comprises a side section Zt, a central section j, and another side section Z. As previously indicated, one of the said side sections may be omitted, in which case the fabric would comprise which would correspond with'the central or and the other with one ofv the side sections. rI`he weftthread indicated at m is from an independent or outside source this the weft of section l is formed. In like manner the thread designated 'o is also from and forms the weft of the section h of t bric. weft p of the central section y' is supplied from two sections, one of i of weft-supply, and fromy The IOO

the shuttle, and,"- as will be clear, is interlocked, as indicated at t, with the, weft of sec- 4tion Z and at the opposite side, as indicated Suppose it to .be

moving (pick number 1) in the direction indicated by the arrow and weft-thread designated 10. the fabric and around theI thread o, which forms the w'eft of section i. Q 'lhe said thread is at the time the shuttle passes around it. occupying the position at the side of the fabto be laying the .It passes across ri(I which'l have indicated by the dotted line ternately over and under the foiii intermediate warp-threads g, imder the next rubber thread f, alternately over and underl four more intermediate warp-threads g, and so on. The next inwardly-drawn )ortion of the weft o, which l lhavedesignate( 14, forms the op'- posite face of the fabric--that is, it passes over the 'wire i. and adjoining i'iib er vthread f, alternatelyunder and over the binderwar threads g, over the rubber threadalternateiy under and yover the next group of four warpthreads, under. the next rubber thread, and so on. This arrangen'ient is practically duplicated b the warp-thread m at the 'opposite side ofr the fabric, as will be clear. A'The same arrangement is also followed in laying the shuttle-wel1 t 7), thereby securing a visible ground-work of weft from side to side of the` fabric and on both faces thereof. rlhe picks are designated at the left of the di'agram'by the numerals 1., 2, 3and 4. The picks ai'e repeated inl these groups of four.

The outer rubber warps f in the side. seetions are )referably located at the extreme edges of the fabric next the -wires a and d, around which the side-section wefts o and/m pass, so that-iii the completed elastic fabric the latter will be edged by rubber war is coveredv only by the side-section wefts,l thus affording the desired elasticity for thc'fabric edges, and by--einploying somewhat large rubber warps a corded efl'eet may be given to the fabric.

By varying the shedding threads .in the well-'known manner a doublefaced fabric may be readily'produced which will be exactly alike on both faces, and if the' three 'sections of the weft are of contrasting colors 'the proximate or meeting edges of each section will be clearly and sharply defined, withl the weft forming the visible ground of passes under.

ofy the lwarpszofi 5 this case one-half of thc fabric-faccwould be formed from weft from the shuttle and the other half of weft from an outside supply.

'The meeting edges pf the two contrasting colors in the center of the fabric may eithei be a straight line or may be giveii'aiiy fanciful design or contour, as desired.
