WOVEN MATERIAL AND METHOD OF PRODUCING THE SAME Filed July 12. 1928 INVENTOR.

W fl wq/izmee A TTORNEYS Patented May 13, 1930 UNITED STATES PATENT OFFICE CARL E. STEIGER, OF OSI-IKOSH, WISCONSIN, ASSIGNOR TO DELTOX RUG COMPANY, OF OSHKOSI'I, WISCONSIN, A CORPORATION OF .WISCONSIN WOVEN MATERIAL AND METHOD OF PRODUCING THE SAME Application filed July 12, 1928. Serial No. 292,217.

My invention has relation to improvements in woven material and method of producing the same.

The invention contemplates, in its broadest aspect, the employment of two strands, one formed of a tough fibre, and the other of a material of greater diameter than the firstmentioned strand, the two strands being twisted together so that the one of greater diameter will extend radially outwardly beyond the strand of tough material, to form the wearing surface, while the latter strand will form an inner core or filling, the two strands so twisted together being particularly adapted for use as the weft thread for a rug, floor covering, or the like.

The invention also, in a more restricted sense, contemplates the employment of two strands for the use above indicated, wherein the strand of greater diameter is made up of a plurality of threads twisted together, a woolen strand being a generic example of a strand of this character, while the other strand is composed of a tougher material,

such, for instance, as used in a cord formed from a twisted sheet of paper, the two strands referred to being twisted together so that the strand of greater diameter is caused to extend outwardly radially to a greater extent than the other.

In a still more restricted sense, the invention contemplates the employment of two strands, one composed of wool, and the other of paper or fibre, the said strands'being twisted together so that the more bulky woolen strand will extend outwardly radially beyond the paper or fibre strand, the cord thus formed being used as a weft thread for a rug, floor covering, or the like, with the wool- 40 en strand forming the wearing surface and the paper or fibre strand forming the core or filler for the woolen strand.

Among the advantages attained by weft thread of the construction referred to, when woven to form a rug, floor covering, or the like, is economy in manufacture, and when wool is employed for one of the strands the appearance of an all wool rug is obtained, while at the same time the springiness inher- 5 ent in all-wool rug is also maintained.

In the accompanying drawing: Fig. 1 is a plan view of a partly woven rug, two portions of the weft thread being pulled outwardly to show clearly the twisted to-.

gether strands of the weft thread.

Fig. 2 is a cross-sectional view on the line 2-2 of Fig. 1; and

Fig. 3 is a view of the twisted together strands to form the weft thread.

Referring, first, to the more specific embodiment of my invention, the numeral 4 indicates the paper fibre strand of the improved weft thread, and 5 the woolenstrand.

Fig. 3 of the drawing shows most clearly the form of the weft thread when the two strands thereof are twisted together, and by reference to this figure, it will be seen that the paper strand, which is more solid and stifier than the woolen strand, forms in effect a core for the woolen strand, with the result that said woolen strand, owing to its flufiy character, due to the fact that it is formed of a number of threads twisted together, extends radially outwardly to a greatnumeral 7 indicates end cross strands, formed of cotton or linen cords, or the like.

From Figs. 1 and 2, it will be seen that the twisted together strands 4c and 5 forming the weft are interwoven with the warp strands, so that each weft strand extends alternately over and under the warp strands. Owing to the fact that the wool strand is more bulky, or of greater diameter than the paper or fibre strand, and the latter strand is more solid or tougher than the wool strands, the latter necessarily, when the two strands are twisted together, projects outwardly radially from'the paper strand, as indicated by the numeral 8,

and thereby constitutes the wearing surface of the rug, the paper strand forming an inner core or filler.

One of the important advantages, therefore, of my invention, particularly where the weft thread is composed of a wool strand and a paper or fibre strand, is that a rug in which such strand is used as a weft thread is not only much cheaper to manufacture than an all-wool rug, but also has the appearance of being madeof all wool, and furthermore has the springiness of a wool rug, and necessarily, as the wool strand constitutes the Wearing surface, the rug has better wearing qualities than a fibre rug.

As before indicated, while the improved weft thread is preferably made up of a wool strand and a paper or fibre strand twisted together, yet I do not desire to limit myself specifically thereto, inasmuch as the strand 4 instead of being-of paper fibre may be of cottomor like tough material. and may be formed from a sheet of material twisted into cord like formation. Also, the strand 5 may be of some other fabrie, it only being essential that it is more bullry than the strand 4, and is of such nature as to be capable of wrapping around the strand or core to form a project ing or outstanding surface.

In this more broad aspect of the invention certain of the advantages heretofore alluded to, are equally present, i e., economy in pro duction, augmented wearing capability, and attractiveness in appearance, due to the fact that the strand which forms the core or filling is almost entirely obscured from View.

lVhat I claim as my invention is:

As a new article of manufacture, a thread for use in the weaving o-f rugs, floor coverings, and the like, consisting of two twisted to gether strands of material, one strand being of; soft yieldmg material, and theother strand being of; a tough fibre material, the said strand of yielding material being of a diameter at least equal to the diameter of the other strand and being of substantially the same length as said strand and the twisting togethor of the two strands producing a cordelike formation in which the strand of soft yielding material extends radially outwardly to a greater extent; than the tOLigh strand, to constitute the wear ng surface, and; in which the tough strand forms an inner core or filling.

in testimony whereof, I atfir mysignature.
