WOVEN FABRIC.

SPECIFICATION forming part of Letters Patent No. 642,971, dated February 6, 1900.

Application filed July 20, 1899. Serial No. 724,568. (No specimens.)

To all whom, it may concern.-

Be it known that I, LEVI FISH, a subject of the Queen of Great Britain, residing at Preston, in the county of Lancaster, England, have invented a certain new and useful Improved l/Voven Fabric Suitable for Dress Goods or other Purposes, (for which I have received provisional protection in Great Britain, No. 1,977, dated January 28, 1899;) and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Theinvention relates to a novel form of cutweft pile woven fabric suitable fordress goods and other purposes of the character to be hereinafter described and which invention constitutes a further improvement or an invention for which British Letters Patent have been granted to me, numbered 14,834, of 1897.

In carrying out my present invention I arrange dobby, jacquard, or equivalent apparatus so as in the process of weaving to bind two or more cloths together in such a manner that when the weft pile threads are subsequently cut on the surface with an ordinary Velvet-cutting instrument the two or more cloths will be separated and readily pulled apart; but instead of this arrangement of weaving being made, so as to produce two reciprocal fabrics, as described in the specification of the British Letters Patent above cited, I arrange the weaving of either the upper or lower cloth (when two cloths only are woven) so as to produce floated weft for cutting into a corded fabric, with the cords relatively closer than can be accomplished by my former method, while the other or inner cloth when separated is a plain woven or other nonpiled fabric, which may be used for an entirely different purpose or considered as a byproduct. Bythis means I am enabled to produce fabrics having loosely-woven backs and yet can out the pile thereof with an ordinary fustian-cutting instrument, as, while the two or more cloths are held together, there is provided by the inner or supplementary cloth a sufficiently firm back to resist the tendency of the point or guide of the cutting-knife to penetrate the cloth and so permit of the successful cutting of the pile on the surface. In

addition to this I may weave leno or other fancy weaving at the back of either the upper or lower cloth, so as to form open-work or other weaving between the cut pile portions of the finished article. The improvements are applicable for the production of this special fabric in the form of cut cords or pile stripes relatively close together of a contin uous or all-over character or may be varied by interspersion of other kinds of weaving therein, so as to form bindings or otherwise,

and other variations in detail may be made, such as in the particular design and materials employed, without departing from the peculiar character of the invention. It will be seen that by this invention I am enabled subsequently to out by the ordinary fustian-cutting apparatus and knife a class of floated weft or pile fabrics which otherwise are impracticable for such treatment on account of their having no rest or resistance during-the act of cutting for the back of the knife. In all cases I therefore weave a non-pile cloth, either as the upper, lower, or inner of the twofold or threefold fabric, whose object is to enable the floated weft of the upper or other cloth or cloths to be cut in a fustian or velvet cutting apparatus after the same has been woven. The mode of weaving is varied according to the particular variety of goods produced; but in the supplementary or inner cloth of the fabric the warp-yarns are so actuated that the weft is always passed therethrough to form a plain or at least a non-piled cloth, which is only separated from the other portions by the subsequent cutting operation and is so woven for the distinct purpose of rendering such cutting operation practicable, and such supplementary or inner cloth may either become a waste or a by-product after the separation thereof or have another use found for it of an inferior character to the cloths it renders by combination possible of production.

The invention is applicable to a large number of designs of pattern; but that the improvements may be better understood I will by the aid of the accompanying drawing proceed to describe the same as applied to one particular pattern or form of cloth-to wit, a cut cord or pile stripes relatively close together of a continuous or all-over character.

The same letters indicate corresponding threads wherever they occur, and the drawing is a graphic representation, irrespective of dimensions, of a transverse section across the cloth in which the points a stand for the ends or sections of warp-threads forming the upper of a double fabric and the points a stand for like warp-threads in the lower of the double fabric, of which those warps indicated by the vertical dotted lines are in this case actuated to form leno-weaving, but which of course is not essential. The waved lines 1) and I) represent weft-threads passed through, forming the ground-Weaving of the upper of the two fabrics, while the waved lines 12 and b constitute the lower-fabric weft-threads, and the lines 0 form the floated weft-threads constituting the pile fabric.

It will be seen that the plain cloth formed by the warps a and the wefts Z2 and Z) are bound to the lower fabric by means of the floating or pile wefts c c and apparentlyconstitute a composite fabric; but when after weaving'the cloth is stretched in a suitable frame, such as an ordinary fustian-cutting apparatus, and the pile-wefts c c are cut asunder at the point indicated by the arrow when the knife is inserted between such pile-wefts and the upper of the two woven fabrics. It will be seen that this upper woven fabriccan be drawn away or clear of the lower woven fabric, leaving such lower fabric with a cut pile and of such a character as could'not otherwise be cut by means of a fustian-cutting knife, this upper or inner plain fabric forming for the'time being a foundation at the back of the knife to enable cutting to take place.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- A compound woven fabric having weft-pile or floated weft portions in the one cloth, and provided with a plain woven or other nonpiled cloth through whichthe pile of the other is caused to pass, thus forming the back of the floated portion of the compound fabric, and which later cloth, while serving the purpose of resisting the back of the fustian-cutting knife, is separated from the rest part of the compound fabric by the act of cutting thepile or floated weft of the cloth, for the purpose and in manner substantially as herein set forth.
