FILE FABRIC.

Specification of Letters Patent.

Patented ea. 12, tote.

Application filed April 16, 1915. Serial No. 21,728.

a citizen of the United States of America,

and residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in File Fabrics, of which the following is a specification.

This invention relates particularly to the heavier fabrics, suh as rugs and carpets.

One object of the invention'is to secure a close, compact weave.

Another object is to provide a structure which can be produced rapidly and economically.

According to this invention the pile warps are arranged'in sets, the pile units of one set being looped over certain weft threads of the structure with intervening weft threads between them and the pile units of a different set being looped over said intervening weft threads. This binds the structure together and produces a close substantial fabric. Binders are woven in with the weft threads and pile units to give body to the fabric and to assist in looking the members together.

Other features will appear as the specification proceeds.

The accompanying drawing illustrates the invention as embodied in several preferred forms, but it will be understood that other changes and modifications may be made without departing from the true spirit and scope of the invention.

Figure 1, IS a perspective view on an enlarged scale of a small portion of fabric embodying the invention in a simple form, the threads constituting the structure being shown separated for the sake of clearness. In this construction a single binder separates two sets of pile from the adjoining two sets and the binders are interwoven with the weft threads and the weft threads are interwoven between the binders and the pile warps. Fig. 2, is a like view of a slightly modified form wherein a single binder separates adjoining sets of pile and the weft threads are interwoven with the Fig. 3, is a perspective. view of another form wherein a pair of intertwined binders separate each two sets of pile from the adjoining sets. Fig. 4, is a similar view of a slightly difi'erent form wherein a pair of intertwined binders separate adjoining sets of pile. Fig. 5, is a perspective view of a form wherein the binders loop over and under pairs of weft threads.

The body or base of the fabric is made up of wefts or weft threads and binders or warp threads combined in various ways.

The pile warps are arranged in two parallel longitudinally extending sets, the units of such setsas cut apart by the pile wires of the loom, being designated 7 and 8 respectively. The units of one set, units 7 for instance, are looped over certain wefts 9 and up around the cross warps 10 at opposite sides of the looped-over wefts 9, and they are separated from each other by an intervening weft 11. The units 8 of the other pile set are looped over these intervening wefts 11, between the units of the first set and up around the wefts 10 at opposite sides thereof. The units of the second set 'thus pass up around opposite sides of the,

. ture is closely woven, as it will be in practice, a firm, durable fabric.

The binders. are designated 15 in Fig. 1. These binders extend longitudinally of the fabric alongside of and parallel to the pile warps, and in this particular case each two sets of pile warps are separated by a single binder. Also here, the binders while interwoven with the wefts are all parallel to each other. v a

In Fig.2 1 have shown how the individual sets of pile units 7 and 8 may be separated by single binders 17 The binders in this case are not parallel, "alternate binders interlacing to. opposite sides of the cross.

This produces a somewhat heavier Different efiects can be produced by varying the relative tensions on the weft threads and binders. Thus in Fig. 2, Where the wefts are placed under greater tension than the binders, the wefts will remain relatively straight while the binders will be more or less sinuous. A reverse effect could be produced by reversing the tensions, making the tension on the binders greater than the tension on the weft threads.

The fabrics produced according to my invention are relatively simple and so can be produced rapidly and economically on a comparatively simple loom construction free of any particular complications. The parts of the fabric are all firmly united and tied together and form a durable, lasting structure.

A special feature, it will be noted, is that each pile unit of one set serves to tie together two adjoining pile units in the other set, each pile unit in a set being looped about the same two wefts which are looped about by adjoining pile units in the other set. The pile units being thus in effect tied together through the intermediacy of the wefts, act in the nature of binders and so give added longitudinal strength to the fabric. This binder effect of the pile units enables the use of smaller binder threads and this of course enables the pile tufts to lie closer together and so form a firmer and more compact fabric. Another important result of this-construction is that at no point of the fabric are adjoining tufts separated by more than a single Weft. The tufts thus lie close together and form a compact firm mass.

Furthermore inasmuch as the tufts are not separated at any point by more than a single intervening weft the fabric is of uniform texture. This uniformity of texture,

provides a continuous interlocking of the pile units'in all directions and so prevents the pile units working loose or being pulled out.

What I claim is 1. A pile fabric comprising wefts, a set of pile units looped over certain of said wefts and up around wefts at opposite sides of said looped-over wefts, adjacent pile units of said set being separated from each other by only a single intervening weft and a second set of pile units looped over said single intervening wefts between the units of the first set and up around the wefts at opposite sides thereof which are looped about by adjoining units in the first set of pile units, whereby each pile unit of one set serves to tie together two adjoining pile units in the other set and whereby adjacent upstanding tufts of the pile units are separated only by a single intervening weft to thereby form a close uniform firm pile structure.

2. 'A pile fabric comprising wefts, binders combined with said wefts and pile units arranged in two sets, the pile units of the respective sets being looped over alternate wefts and under and up around the wefts between said looped-over alternate wefts, each pile unit in each set being looped over a weft between adjoining pile units in the other set and up around the same wefts which are looped about by the adjoining units in the other set and thereby tying together the adjoining pile units in the other set and providing in effect a substantial continuity of the pile units.

3. A pile fabric comprising wefts, a set of pile units looped over certain of said wefts and up around wefts at opposite sides of said looped-over wefts, adjacent pile units of said set being separated from each other by only a single intervening weft and a second set of pile units disposed alongside and immediately adjoining the first set of pile units and looped over said single intervening wefts between the units of the first set and up around the wefts at opposite sides thereof which are looped about by adjoining units in the first set of pile units, whereby each pile unit of one set serves to tie together two adjoining pile units in the other set and whereby adjacent upstanding tufts of the pile units are separated only by a single intervening weft to thereby form a close uniform firm pile structure.

4. A pile fabric comprising wefts, pile units arranged in two sets, the pile units of the respective sets being looped over alternate wefts and under and up around the wefts between said looped-over alternate wefts, each pile unit in each set being looped over a weft between adjoining pile units in the other set and up around the same wefts which are looped about by the adjoining units in the other set'and thereby tying together the adjoining pile units in the other set and providing in effect a substantial continuity of the pile units and a single binder disposed between certain of the adjacent sets of pile units and interwoven with the wefts aforesaid.
