WOVEN FABRIC.

SPECIFICATION forming part of Letters Patent No. 789,130, dated May 2, 1905. Continuation of Serial No. 171,168, filed August 29, 1903.. This application filed March 21, 1905. Serial No. 251,228-

T0 on whom it may concern:

Be itknown that LHovoEP SARAFIAN, a citizen of the United States, residing at Yonkers, in the county of Westchester and State of New York, have made certain new and useful Improvements in Woven Fabrics, of which the following is a specification.

It is the object of my invention to produce an improved fabric which shall be distinguished by cheapness and yet present an ornamental appearance. The same is composed of a body or under portion consisting of cheap yet strong and durable materialsuch, for example, as cotton or jute-and a top or surface portion consisting of better and more ornamental material, such as worsted or silk.

The invention is embodied in the manner of arranging the threads or strands composing the ornamental surface material and the weft for tying in or securing of the same to the body or bottom portion.

The details of the invention will be understood by reference to the accompanying drawings, in which Figure 1 is a plan view illustrating the arrangement and interweaving of the top or ornamental material with the body of the fabric. Fig. 2 is a longitudinal section on the line 2 2 of Fig. 1, the several threads or parts composing the fabric being shown widely separated for the sake of clearer illustration. Figs. 3 and 4 are diagrammatic cross-sections on the lines 3 3 and 4 4, respectively, of Fig. 1. Figs. 5 to 10, respectively, are diagrammatic illustrations of the shiftings of the several threads or strands composing the fabric in the process of interweaving.

Referring in the first instance especially to Figs. 1 and 2, the numeral 1 indicates ordinary or ground warp-threads, and 2 the ordinary filling or weft, the latter being composed of thick or heavy strands. These two parts 1 and 2 constitute the body or under portion of the fabric 1, as before stated, and are composed of cheap material, such as cotton or jute. The top or ornamental surface,

formed of worsted, silk, or other material superior in quality and appearance to the body portion, is composed of strands or threads 3, which have considerable bulk or diameter and are interwoven and tied to the body in the following manner. In Fig. 2 it will be seen that the strands 3 are so arranged that each loop or overshot spans two of the ordinary weft or filling 2 and that this occurs in such manner that the loop of one strand is adjacent to the'depressed portion of the next strand 3, which is tied into the body. The tying in or interweaving is effected by means of small weft-threads 4, which are preferably colored in order that they may present an ornamental appearance in the top surface of the fabric, where they appear between every two adjacent strands 3, as shown in Fig. 1. As shown in Fig. 2, this bindingweft 4 passes between the warp-threads 1, this being effected in the usual manner by means of a shuttle when the warp -threads form a shed. Thus the binding-weft4 passes between the crossed warp-threads 1 in every space that intervenes two strands of the parallel weft 2. As shown, the binding-weft 4 passes alternately over and under the ornamental warp or surface covering 3. The details of arrangement of the several threads 1 to 4, inclusive, will be better understood by reference to the enlarged diagrammatic sections, Figs. 3 and 4, and the shiftings or changes which occur in the process of weaving will be further understood by reference to Figs. 5 to 10, inclusive. It will be understood that the warps 1 and 3 are raised and lowered, as in ordinary weaving, by means of heddles or any other suitable appliance and that the filling and binding wefts 2 and 4 are introduced by shuttles in a well-understood manner which requires no particular description.

and the ground-warp 1 crosses in the ordinary way and passes and binds in the thick weft 2, then (see Fig. 9) another ornamental warp 3 follows its mate or ground-warp 3 down, and the thin binding-weft 4 passes over such ornamental warp. In the fabric produced by this methodof weaving allthe ground warp-threads are covered by the ornamental warp-threads.

By the construction and arrangement of parts as above described and illustrated in the drawings I form a fabric having a strong, cheap, and durable body portion and presenting on its top surface the appearance of a higher-priced fabric. It will be noted that the worsted or top warp being so tied in that the loops of any strand are opposite depressed portions of other strands the loops have space to spread out laterally, so as to cover the underneath portion with a better ornamental effect and a greater economy of material than would be otherwise practicable. The invention has a wide application, but is particularly adapted for cheap carpets.

The fabric may be woven of printed yarn or threads, or the surface formed by the warp 3 may be printed after having been Woven into and made part of the fabric.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent 1. The improved fabric consisting of an under portion formed of ordinary Warp and thick weft threads interwoven, and a top or covering portion formed of thick ornamental warp whose strands span a plurality of weft-threads, and thin weft-threads passing between the ordinary warp and over the ornamental warp thus binding the latter at regular intervals to the under portion of the fabric substantially as described.

2. The improved fabric composed of the under portion formed of ordinary warp and thicker weft threads interwoven, and the top or covering portion formed of thick ornamental warp, and thin weft-threads which pass between the ordinary warp-threads and over the said ornamental warp, the loops of the latter spanning a series of the thick weftthreads and being arranged opposite depressed or tied-in portions of the ornamental warp as shown and described.

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

HOVCEP SARAFIAN.
