WILLIAM T. SMITH, OF PHILADELPHIA, PENNSYLVANIA.

WOVEN PILE FABRIC.

SPECIFICATION forming part of Letters Patent No. 691,193, dated January 14, 1902.

Application filed October 28, 1901. Serial No. 80,233. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM T. SMITH, a citizen of the United States, residing in Philadelphia, Pennsylvania, haveinvented certain Improvements in Woven Pile Fabrics, of which the following is a specification.

Myinvcntion relates to that class of fabrics intended to simulate an oriental rug, these fabrics having a cut-pile face with elaborate patterns both as to figure and coloring and having a plain back on which the figure is partially outlined by portions of the pilethreads drawn through to the back.

My invention consists of a fabric which can be cheaply produced upon a loom, such as that employed for a Smyrna rug, the essential feature of the invention being the means employed to stifien the chenille fur, which constitutes the patterned face of the fabric, and to prevent said chenille fur from being drawn to the back of the fabric except to the limited extent desired.

In the accompanying drawings, Figure 1 is an exaggerated section of apiece of fabric constructed in accordance with my invention, the section being taken in the direction of the warp; and Fig. 2 is alike exaggerated section of the fabric, taken in the direction of the weft.

The fabric comprises repetitions of two warp-threads 1 and 2 and three weft- threads 3, 4, and 5. The warp-threads 1 are separator Warp-threads which extend throughout the fabric and serve to separate the face and back weft-threads and also to determine the longitudinal stability of the fabric by prevent-- weft-threads 4 are heavy-spun threads, which constitute the back of the fabric, and the weft-threads 5 are finer threads, which lie alongside the chenille-fur weft-threads 3 in the same shed of binder-warp, and thereby impart stifiness to the bunch of threads constituting the core of the chenille, so as to cause the fur or pile ofo the same to stand up well and rise after being depressed, thereby preventing the pile-surface of the fabric from showing foot-prints. The fine weft-threads 5 also serve to limit the extent to which the chenille fur can be drawn down by the binding warp-threads 2 between the back weftthreads 4. Hence only a limited amount of the chenille pile or fur is visible on the back of the fabric, sufficient to faintlyindicate the outlines and coloring of the pattern, as in an ordinary expensive oriental rug.

In weaving the fabric ashed is first formed by raising the binding warp-threads 2 and lowering the separator warp-threads 1, and into this shed is shot first the chenille-fur weft-thread 3, which is properly adjusted laterally to accord with the pattern on the preceding chenille Weft-thread, after which the weft-shot 5 is inserted and beaten up. The shed is then changed, the binding-threads 2 being lowered and the separator-threads 1 raised, and the back weft-thread 1 is then shot in and beaten up, these operations being repeated indefinitely.

Having thus described my invention, I claim and desire to secure by Letters Patent- A woven fabric comprising face weftthreads of chenille fur, reinforcing face weftthreads, eachin a shed with one of the chenille weft-threads, heavy back weft-threads, separator warp-threads interposed between the face and back weft-threads, and binding warp-threads alternating with the separator warp-threads and tying together the face and back weft-threads, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM T. SMITH.
