ABRAsIvE FABRIC.

Original application filed May 16, 1.924, Serial No. 713,724.- Divided and thisl application filed. May 2, 1925. Serial No. 27,410.

To all whom t may concern.'

Be it known that I, It-UssnLL B. KiNcarnN, acitizen of the United States, residingl at Orange, in the ycounty of Essex and State of New Jersey, have `invented certain new and useful Improvements in Abrasive Fabrics; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates, generally, to improvements in abrasive fabrics; and more particularly to shrinlrless abrasive fabrics as set forth in my co-pending application for Letters Patent Ser. No. 713,724, filed May 16th, 1924, and of which the present application is a. division. l

The present invention has for' its princi al object to provide an abrasive fabric consisting of metal gimped weft threads or strands with which are interconnected or knitboth vegetable yarn and metallic cross threads so related to one another that not only is a highly efficient abrasive uality imparted to the fabric, but the finis red fabric is adequately braced against shrinking, andv consequently' clothsand other `scouring articles made therefrom definitely and 'positively retain their shape, and therefore always present in use a desired comparatively fiat abrasive surface. Furthermore, in the novel fabric, possessing the said shrinkless char acter, the meshes thereof remain open, so that thorough cleansing of the cloth after use is easily accomplished, whereby the same may be easily kept` in a clean, sweet and sanitary condition, free fromaccumulations df dirt and grease.

With the above objects of the present invention in View, the same consists in a fabric comprised of suitable spaced weft threads or strands of suitable material, such as vegetable yarn, jute or like base material, which are gimped' with one or more metallic threads or strands by spirally winding, twisting or convoluting the latter about the former from end to end. Itis'preferable that the metal gimping should be done with thin ribbon-like or iat wire made of a noncorrosive metal possessing a suitable degree of hardness, such, for example, as copper. The metal gimped weft threads are interconected and held together, in suitably spaced relation one to another, by vegetable yarn cross threads or strands, which are preferably interloopcd or knit by a lock or chain stitch transversely across the spaced gimped weft threads, and alternated with said vegetable yarn cross threads or strands are metallic cross threads or strands in separatc parallel spaced relation thereto, said metallic cross threads being also preferabl interloo ed or lmit with the gimped we t threads y a lock or chain stitch. By the described alternated parallel relation of said vegetable yarn and metallic cross or weft threads, the vegetable Yyarn cross threads provide a desired degree of water absor tive material in addition to the body of tie weft threads, while the metallic. cross threads provide abrasive elements in addition to that provided by the gimping of the weft threads, while at the` same time serving to' firmly brace the iinished fabric against contraction or shrinkage. Said metallic cross threads may be of any desired cross-sectional shape.

This invention is clearly illustratedin the accompanying drawings, in which Figure 1 is a face view of a square of the novel abrasive fabric made according to the principles of this invention gv and Figure 2 is an enlarged fragmentary detail face view `of the same.

In producing'the novel shrinkle'ss abrasive fabric embodying the principles of this invention, I take a base thread 3 of any suitable material, preferablymade, however, of a vegetable fiber such as jute, and I twist or turn around the body` thereof one ormore metallic strands 4, thereby gimping such base thread 3 with metal, so that abrasive elements are rovided ,by the convolutions of suchmetal ic material. I prefer to use a form of metallic strand which will, .when thus convoluted or gimped on the base thread, provide a multiplicity of sharp edges or projections, so that a maximum of abrasiveefficiency is attained, and, therefore, I select for the purpose a thin ribbon-like or fiat copper wire, although I do not intend to linut myself necessarily to wire of such vide for such comparatively Wide spacing of the weft threads inthe iinished fabric, l knit the cross threads to form interlocked loops or links, which surround and hold the weft threads both strongly interconnected as Well as spaced apart at the proper distance,

according to the size of-1nesh desired. In

the instant species of my 'invention' I eniploy cross threads of two different materials, tov Wit, cross threads 5 of vegetable yarn, such, for example, as cotton, and cross threads 6 of metallic Wire, such as copper. The yarn cross threads 5 and metallic cross threads 6 are disposed in alternated parallel relation, at desired spaced intervals throughout the total area of the fabric. By such arrangement a metallic thread 6 will be dispcsedadjacent to a yarn thread 5, andthus the yarn threads will be braced against contraction when the fabric is Wet, because ci the resistance of the metallic threads 6 to such contraction, and consequently the entire fabric is rendered substantially shrinkless. At the same time the metallic threads 6 serve to provide additional abrasive acrecare? tion, since the same provide additional metallic projections -distributed transversely throughout the area of the fabric. From the above it will be understood, that the fabric so constructed Will easily retain the desired flat open mesh condition and shape, whereby not only is its abrasive efficiency increased, but it is also the more readily subjected to thorough cleansing and rinsing to free the same from the dirt and grease accumulated thereon When in use, and-consequently may be easily kept in a clean, sweet and sanitary condition.

I claim 1. An abrasivewfabric comprising weft threads gimped with metallic Wire, yarn threads interconnected to and across said weft threads to produce an open mesh, and all-metal threads also interconnected across said Weft'threads in separated and alternated parallel relation to said yarn threads -at desired intervals relativeto the length of said gimped weft threads. p

'2., An abrasive fabric comprising jute WeitA threads gimped with flat metallic Wire, vegetable yarn t reads knitted across said weft threads to space the same apart to produce an open mesh, and additional threads of metallic Wire also knitted across said weft threads in separated and alternated spaced parallel relation to said yarn threads throughout the area of the fabric.

in testimony that I claim the invention set forth above I have hereunto set my hand this 30th day o-April, 1925.

RUSSELL B. KINGMAN.
