CUT PILE FABRIC.

SPECIFICATION forming part of Letters Patent No. 391,652, dated October 23I 1888,

Application filed February ll. 1888. Serial No. 263,741.

To aZZ whom it may concern:

Be it known that I, TOM I. SHUTTLEWORTH, a citizen of the United States, and a resident of Amsterdam', Montgomery county, New York, have invented certain Improvements in Gut'Pile Fabrics, of which the following is a specification.

My invention consists of a certain improvement in that class of pile fabrics which are woven double and subsequently cut apart, the object of my invention being to facilitate the weaving of such double fabric, and to produce a fabric having a firm back and close pile with the use in each fabric of a less number of figuring warp-th reads than are employed in making the usual single fabric. This obj ect I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure lis an exaggerated diagram illustrating a section of my improved fabric, the section being taken on a line transversely to the warp. Figs. 2 and 3 are longitudinal sections, respectively, on the lines l 2 and 3 4, Fig. l; and Fig. 4 is a view illustrating a slightly modified form of thefabric.

In the-present method of producing figured cut pile fabrics by weaving the fabric double, carrying the figuring warp-thread across from one backing to the other, and then severing these figuring warp threads midway between the two backings, it is the usual custom to dis-` tribute the figuring warp-threads in each fabric uniformly from one side of the fabric to the other-that is to say, there will bein both the upper and lower sheds a certain proportion of figuring warp-threads for each dent of the reed, and where stuffing-warps are used the dents are unduly crowded and free shedding of the warps is interfered with. I desire to overcome this objection, and yet adhere to the plan of weaving the fabric double and then cutting it apart, so as to produce a fabric hav ing a firm body and a sufficiently close pile with considerably less than the amount of nguring-warp now used in making a cut pile fabric by the usual plan of weaving the fabric with loops and then cutting the latter. I therefore alternate the disposal of the sets of figur- (No specimens.)

ing warp-threads in the two sheds. Thus, for example, the upper shed may have sets of figuring warp-threads disposed in the dents l 35 7, Src., of the reed, there being no figuring warp-threads in the dents 2 4 6 8, the., While in the lower shed the disposal of the sets of figuring warp-threads is reversed, said sets occupying the dents 2 4 6 S, &c;, of the reed, while there are no figuring Warpthreads in the dents l 3 57, 85e., the vacant dents of the reed in each shed bei ng occupied by the stuffingwarps, which therefore do not in any way interfere with the free shedding of the guriug-warps in the other dents of the reed. The consequence of this is, that viewing the fabric transversely,

as in Fig. l, the pilev is formed alternately by a thread drawn down from the upper backing and looped into the lower backing, and by a thread drawn up from the lower backing and looped into the upper backing, and when the fabric is severed the pile will be formed by longitudinal rows of tufts projecting upward from the bac-king, the tufts ofevery other row consisting of the projecting ends of figuring warp-threads extending from end to end of the fabric and buried in the backing, while the tufts of the alternate rows consist of the projecting ends of independent loops simply tied into the backing bythe filling-threads, the stufting-warps being disposed alongside of these rows of independent loops, so as to provide for the proper stiffcning of the fabric.

In the drawings, the letters a represent the figuring warp-threads, b the binding-warps, d the stufing-warps, and f the binding-wefts, three of these being used in the present instance for each transverse row of pile-loops, although more or less than three binders may be used, if desired.I

In carrying out my invention it is not absolutely necessary that the tufts derived from the threads buried in the backing and the tufts formed by the independent loops should be in single rows, as a series of rows of tufts formed by independent loops may alternate with a series of rows of tufts derived from the buried warps. (See Fig. 4, forinstance.) I/Vhere two stufiing-warps are used for each row of tufts formed by the independent loops, one of said warps may be on each side of the row of tufts, ternate rows Consisting of tufts formed'by sinas shown at d in Fig. v4I. gle independent loops tied into the backing Having thus described my invention, what and disposed by the side of one o1' morestnfng- I claim, and desire to secure by Letters Pat- Warps, all substantially as specified. i5 5 ent, is In testimony whereof I have signed my naine A out pile fabric in which binding warps to this specification in the presence of two suband wefts and stufng-warps forming a, bncksoribing witnesses.
