WOVEN PILE FABRiC- SPECIFICATION forming part of Letters Patent No. 782,1 8, dated February 7. 1905.

Application filed April '7, 1904, Serial No. 202,059.

To Ilj/ //-/mmit may (Io/worn.-

Be it known that I, Hovonr SARAFIAN, acitizen of the United States, and a resident of Yonkers, in the county of \Vestchester and State of New York, have invented a new and Im proved \Voven Pile Fabric, of which the following is a full, clear, and exact description.

The invention relates to woven pile fabrics such as shown and described in the Letters Patent of the United States No. 752,712, granted to me February 23, 190%.

The object of the present invention is to provide a new and improved woven pile fabric in which the piles extend in one direction and a long pile can be used and at the same time an exceedingly-strong fabric can be readily produced on a loom of simple construction.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter andthen pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is an enlarged longitudinal section of the improvement. Fig. 2 is a like view of the same, showing alternate face-loops drawn down onto the face of the body of the fabric. Figs. 3, 1, and 5 are cross-sectional views of the weave. Fig 6 is a perspective view of the finished fabric illustrated in Fig. 2; and Fig. 7 is a plan view of the improvement,show ing the use of a drum-printed pile warpthread.

The body of the woven pile fabric illustrated in Fig. 1 is formed of sets of ground warpthreads, each set containing at least two continuous ground warp-threads A A, of which for convenient distinction I prefer to call the ground warp-thread A the upper ground warp-thread and the other ground warp-thread A the lower ground warpthread, and the sets of ground warp-threads are suitably interwoven with binding weftthreads 8 and B, and each set of ground warp-threzuls is also interwoven with a con- 1' by simple mechanical operations.

tinuous pile warp-threzul 0, having lower or bottom loops C looped around the lower ground warp-thread A and passing between the ground warp-threads to form upper or face loops C", extending a distance above the upper ground warp-threzul A and adapted to be cut at l) to produce a pile-surface. In weaving the fabric each pile warp-thread C preferably starts from the left to the right of a pair of ground warp-threads A A. In starting from the left to the right and after the first weft-thread B is inserted the pile \varp-th read C passes down on oneside of the upper ground warp-thread A. then between the ground warp-threads A A of a pair of warp-tln'eznls, to then loop around the lower ground warp-thread A to form the bottom loop G, and to again pass between the ground warp-threads A A and then rise on the opposite side of the upper ground warp-thread A. The pile wz'u'p-thread U now makes the faceloop C" a distance above the upper ground warp-th read A and over a wire or knife, which cuts the loop U at l), and then the pile warpthread U passes down on the same side of the upper ground warp-thread A and between the ground warp-threads A A to form the other bottom loop C The pile warp-thread C then passes between the ground warpthreads A A to rise on the other side of the upper ground warp-thrmd A and form another face-loop C. The pile warp-threzul C extends from the face-loop C downward between the ground warp-threads A A to be looped around the bottom ground warp-threzul A to form the next bottom loop (1, and the above-described operation is then repeated that is, the pile warp-thread is extended up between the ground warp-threads A A over a wire or knife to form the next face-loop C, and so on. The warp-thread A passes in front of the ground warp-threzul A at the crossing and binding-in portion of the ground warp-threads A and A and also passes in front of the pile warp-thread C at the loop C, located at the crossing and binding-in portion of the ground warp-threinls A and A, and by this arrangement 1 am better enabled to produce the weave In very closely weaving the fabric the ground warpthreads A A of a set of ground warp-threads stand approximately one above the other, as plainly illustrated in Fig. 3; but in case the weaving is less close then the ground warpthread A of a set of ground Warp-threads appears staggered relative to the ground warpthread A, as shown in Fig. 4:, and when the fabric is loosely woven the ground warp-thread A of a set of ground warp-threads appears approximately alongside its mate A, as indicated in Fig. 5. It is understood that the relative tension given to the ground warpthreads A A of a set of ground warp-threads produces the result as to the relative location of the ground warp-threads to each other, as above mentioned.

In the modified form illustrated in Fig. 2 the pile warp-thread C forms lower or bottom loops C C and alternate face-loops C C", of which the face-loops (J extend a distance above the faceof the body of the fabric and are adapted to be cut at D to produce a pilesurface. The other face-loop remains uncut and is drawn down onto the upper face of the body of the fabric at the crossing of the ground warp-threads A A The ground warp-thread A passes in front of the uncut loop C and in front of the other ground warpthread A at the crossing and binding-in portion of the ground warp-threads A A, the same as above described in reference to Fig. 1 and for the same reason.

Fig. 6 shows an enlarged perspective view of the finished fabric just described, and by reference to this figure it will be seen that each individual pile has two bottom loops and one face-loop, the bottom loops being looped around the bottom ground warp-thread A and the side members of the pile all stand inclined in the same direction with the faceloop C between the said side members. By this arrangement each pileis very firmly interlocked with the ground warp-threads to prevent the piles from becoming detached when the fabric is used. By drawing the loops down a large amount of pile warpthread is saved; but, if desired, a very long pile-loop C can be made to produce long piles. It will also be seen that by drawing the face-loop O firmly down onto the face of the body of the fabric an exceedingly strong and durable body is produced in which the piles are not liable to become loose or pull out when using the fabric as a rug, for instance.

As shown in the drawings, alternating binding weft-threads B and B are employed, passing between the ground Warp-threads A A directly below the face-loops C as shown in Fig. 1, or below the face-loops (J C, as illustrated in Fig. 2. The ground warp-thread A, Fig. 1, (or A Fig. 2,) passes under the weftthreads B and over the weft-threads B, while the ground warp-thread A, Fig. 1, (or A, Fig. 2,) passes over the weft-threads B and under the weft-th reads B.

Although I prefer the arrangement of the weft-threads B and B as described, it is evident that more or less weft-threads may be employed, according to the density desired to be given to the body of the fabric.

By reference to Figs. 1 and 2 it will be seen that each warp-thread in its upper position is on the same side of the pile warp-thread, and hence in the finished weave the said upper warp-thread portions tend to incline all the pile ends in one direction to give the pile-face a very desirable sheen similar to the one appearing in oriental rugs. It will also be noticed that the adjacent pile-arms of successive piles stand on the same side of the corresponding warp-thread A A. (See Fig. 7.) It will also be seen that each pair of ground warp-threads A A is interwoven with its own pile warp-thread C, and in case a figured pileface is called for then the pile warp-thread C (or C used is one that is colored in sections or what is technically known as drum-printed. (SeeFig. 7.) Byreferencetothisfigure,

which is a plan view of the fabric shown in r Fig. 5, the ground warp-threads A A appear spaced apart and the pile warp-thread C (or C appears as in the finished fabric-that is, beaten up by the lay of the loom and the pile-loops appear cut to produce a pile-face in color, according to a predetermined design.
