To all whom "it may concern.'
Be it known that I, RUSSELL B. KINGMAN,
a citizen of the United States, residing at Orange, in the county of Essex and State of New Jersey, have invented certain new andv useful Improvements in Knit Abrasive Fabrics and Articles Made Therefrom; 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.
The invention relates to improvements in abrasive fabrics; and the invention has reference, generally, to a novel construction of abrasive fabric, and .more Specifically to a tubular knit abrasive fabric for manufacturing scouring cloths, mits and `similar articles.
The invention has for its principal object to provide an abrasive fabric comprising a suitable base thread knitted to form a' tubular body, said base thread being gimped with a thin ribbon-like wire made of a preferably non-corrosive metal possessing a suitable degree of hardness, such, e. g. as copper, which istwisted or turned around the body of the base thread. The tubular knit fabric thus produced, by reason of the interlooping of its Stitches, tends to irregularly dispose the twists or turns of the ribbon-like wire, so that the same project from the surface of the finished fabric ata great variety of projecting angles, thus greatl increasing the abrasive qualities of the abrio, while the substantially iiat and even surface provided by the knit body Supports such projections so that a greater number of projections, per
iven square area of fabric, may be brought into contact with the surface uponswhich the fabric is rubbed, than is the casewith a woven fabric, all of which greatlyiincreases the eiciency and durability of scouring articles made out of such novel fabric.
The tubular knit abrasive fabric of the novel character about outlined, renders it possible to manufacture scouring mits Vand similar articles, so that the same are seamless, except for the stitchin required to close one end of the tubular ody, and conseuently the finished article better retains its s ape in use, while at the same time a superior article can be made with less labor,
and more cheaply and quickly.
Other objects of this invention, not at this time more particularly enumerated, will be clearly understood from the following detailed description of the same. A v
The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a perspective diagrammatic view of a section of the novel Seamless or tubular knit abrasive fabric, made according to and embodying the principles of this invention; Figure 2 is a face view of a fragment of the novel fabric drawn on an enlarged Scale; Figure 3 is an elevation of a piece of the base thread gimped with at metallic wire from which the novel tubular fabric is knitted; and Figure 4 is a face view of a seamless Scourin mit made out of the novel tubular knit fa ric.
Similar characters of reference are employed in all of the hereinabove described views, to indicate corresponding arts.
In producing the novel abrasive fabric, I take a base thread a, which may be of yarn, jute, cord, metal wire or other suitable material, and I twist or turn around the body thereof one or more ribbon-like metallic wires b (see Figure 8). The base thread a, thus imped with metallic wire b, being prepare the same is delivered to the needles of a tubular knitting machine, whereby a tubular fabric A. consisting of a series of rows of interlooped stitches or meshes is produced see Figure l). As will be quite apparent rom an inspection of Figure 2 the twining of the gimped main or base thread to form intermeshed loops during the process of knitting, results in a constant or successive shift of the angles of projection of the sharp bends of the ribbon-like gimping wire b, so that in the finished fabric, the sharp scraping edges presented at the surface of the latter by such projecting bends of the wire b, are presented or extended in many dierent directions, thus tending, when the fabric is in use, to produce upon the surface to which the fabric is applied and rubbed, a strong abrasive action no matter in what direction the fabric may be moved during such operation. Furthermore, owing to the substantially flat character of the knitted fabric, the abrasive surface, produced by the projecting edges of the bends of the wire b, is comparatively even and true, so that a greater multiplicity of such projecting abrasive bends or edges for a given area of fabric are presented. against a surface over which the fabric is rubbed, than is the case with woven fabrics. Another advanta e of the knitted fabric is that the even ormation of intermeshed loops tends to rodnce a fabric Which easil mamtains its s ape, and yet is o en enoug so that the same may be readiy cleansed from grease, dirt, etc., which may accumulate therein when the fabric is employed in scouring operations.
The novel tubular knit fabric of the character above set forth is most admirably adapted for the production of scouring mits, pot cleansers and similar articles, which are made in the form of a two-fold body open at one end for the insertion of the hand of the user. For such articles the novel tubular knit abrasive fabric provides a seamless two-fold body, which may be formed into a mit, by closing one end by suitable stitching or other fastening means. Such an article thus made is illustrated in Figure 4, in which the reference character c indicates thetWo-fold seamless body of the novel tubular knit abrasive fabric, one end of the same being closed by suitable stitehing d or other fastening means, thus completing by very simple and quick operations the manufacture of the mit-like scouring device. The scouring mit thus made will easily' kee its sha e, and can be readily and quick y cleanse In the manufacture of the novel tubular knit abrasive fabric, I may make lan all metallic fabric by using a suitable metallic wire for the main or base thread-Which is gimped with the additional ribbon-like metallic Wire; or I may make various forms of combination fabrics, in which the main or base thread is made of yarn, cord, 'nte or the' like gimped with the ribbonike metallic Wire.
I claim An abrasive fabric made of a base thread varound which is convoluted a thin ribbonlike metallic Wire adapted to present by its convolutions a multiplicity of sharp abrasive edges, said base thread so formed being knitted into a seamless tubular body providing rows of intermeshed loops which by their turns project said sharp abrasive edges of the convoluted Wire in many different directions.
In testimony that I claim the invention set forth above I have hereunt'oset my hand this 9th day of June, 1923.
