WOVEN PILE FABRIC.

Specification of Letters Patent.

Original application filed December 7, 1917, Serial No. 205,938. Bivided and this application filed May 10, 1918. Serial No. 233,626.

To all whom it may concern:

Be it known that I, FREDERICK O'r'r, a citizen of the United States, residing at Norristown, in the State of Pennsylvania, have invented a certain new and useful Improvement in Woven Pile Fabrics, whereof the following is a specification, reference being had to the accompanying drawings.

My invention relates to warp-piled fabrics of the double plush class which, when separated, form two textures which are alike.

The peculiar arrangement of the pilev threads in accordance with my invention not only produces pile facings of uniform density for the respective textures, but effects a more general interlocking of those threads with the backing threads, than in ordinary fabrics of said class, and, consequently, renders my improved fabric more firm and durable than such ordinary fabrics.

Moreover, in such ordinary fabrics the ground threads are so arranged as to form plain cloth backs for said textures; whereas, the ground threads in my fabric may be arranged, as hereinafter described, to form backing cloths for the respective textures, which are twilled, to render them more pliable than plain cloth, for furniture coverings and draperies.

My invention includes the various novel features of construction and arrangement hereinafter more definitely specified.

In the drawings: Figure I is a'diagrammatic plan view of one pattern block of a double. fabric embodying my invention; looking downward upon the back of the upper texture shown in Fig. II.

Fig. II is a diagrammatic longitudinal sectional view of the single texture, the back of which is shown in Fig. I; taken on the line II-II in, that figure, to show the relatively staggered course of a pair of ground warp threads. Fig. III is a plan view looking downward on the back of the upper texture shown in Fig. IV. Fig. IV is a longitudinal edge view of said pattern block of the double fabric, showing the general course of the warp pile threads. Fig. V is a diagram indicating the order of shedding of both the ground and pile threads of said fabric.

In Figs. I and III, the horizontal rows of squares represent warp ends and the vertical rows of squares represent picks of weft. Accordingly, in Fig. V, the horizontal lines represent warp ends and the vertical lines represent successive shedding operations; and the order in which the respective warp ends are drawn up in the shedding operations represented by Fig. V is indicated by the m marks at the junctions of the lines in said figure.

Said fabric is conveniently made with four backing 'ends and four pile ends in one dent; and with six backing heddles, shedded in the order indicated in- Fig. V; wherein the horizontal lines 1 to 6 inclusive indicate six warp ground threads, and the horizontal lines 8 to 13 inclusive indicate six Warp pile threads. The vertical lines in said figure indicate the twenty-four shedding movements necessary to complete the pattern; each of said threads being raised to the surface of the fabric in the order indicated by the marks as thereon, considered from left to right in said figure. Said threads are thus identified in the other figures, which show patterns, each including twelve pile threads, which may be repeated transversely with respect to the respective fabrics, to any desired width, It may be observed that said pattern includes three series of said pile threads, each including twopairs of pile threads shedded alike, but unlike the adjoining series; but that said pile threads are divided in groups of two,

transversely with respect to the fabric, by

respective groups of "ground threads.

The fabric herein claimed is thus distinguished from that claimed in my application Serial No. 205,938, of which this application is a division; the specific claims in that application being limited to a fabric in which the pile threads are divided in groups of four; transversely with respect to the fabric, by respective groups of ground threads. Moreover, in that case. I prefer to arrange the ground warp threads in groups each consisting of four threads, dividcd in pairs to the respective textures, the members of which pairs, instead of being simultaneously shedded up and down are shedcled successively in relatively staggered relation in a two up and one down manner with reference to the backs of the textures. On the cont'rary,in the present case, I prefer to arrange the ground warp threads in" groups 15, each consisting of two threads, divided singly to the respective textures, but in the same relative staggered relation, and two up and one down manner, with reference to the backs of the textures. However, I do not desire to limit myself to such specific arrangement of the ground threads.

In the patterns shown in Figs. I to V, the groups 15 of said warp ground threads 1 to 6 extend singly and alternately, between said pile thread pairs which are shedded alike, and between those which are shedded unlike; such arrangement being thus distinguished from that claimed in my copending application Serial No. 205,938, wherein the Warp ground threads extend only between the pile thread pairs which are shedded alike.

Said warp threads are shedded in a reclining twill in the backs of the respective textures; thus affording a desirable degree of pliability, despite the firmness of the fabric. However, as they present a corresponding twilled effect in the respective pile facings formed by cutting said double fabric between its backing textures, it is to be noted that the twill is less visible in the specific form herein claimed than in the form claimed in my copending application Serial N 0. 205,938 aforesaid. However, I do not desire to lim1t all of my claims to such twilled arrangement or effect.

Therefore, I do not desire to limit myself to the specific construction and arrangement herein set forth, as it is obvious that various modifications may be made therein, without departing from the essential features thereof, as defined in the appended claims.

I claim:
