SCOURIN G DEVICE.

Application led May 22, 1924. Serial No. 715,070.

To all whom it may concern: Y

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 6 New Jersey, have invented certain new and useful Improvements in Scouring Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled 10 in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, andto characters of reference marked thereon,vwhich form a part of this specification.

This invention relates, generally, to an improved scouring device; and the invention has reference, more particularly, to a novel construction of hand implement or device peculiarly adapted for use as a kitchen or household aid for cleansing and brightening surfaces which require the application of abrasive action thereto, such, for example as pots, pans and various other househol utensils. 'l

The invention has for its principal object to provide a novel construction or form of device adapted to furnish a yieldable or resilient spongiform spheroidal abrasive mass which is splinterless because the material out of which it is formed is knit 4or woven from continuous strands or threads of metallic wire or a composite of metallic wire and vegetable yarn, and which is formed iu a novel manner so as to be provided with ain enveloping exterior continuouscover portion enclosing the mam mass thereof and composed of one or more layers or plies of the abrasive fabric. The novel scouring device, in the form of a spongiouter cover or casing, is very durable and strong, and is adapted toiretain its shape 1n use, since the enveloping continuous cover portion eiciently holds and retains the center core or mass in` initially balled together state, and therefore the device long withstands the effect of surface wear. The durability of the device is particularly increased when the cover portion is formed with a plurality of plies or layers; for, in such case, even after surface wear opens up the outer layer orv layers the inner layer will still retain the shape of the (levierl and delay disintegration thereof.

form spheroidal mass having an enveloping Other objectsof this invention, not at this time more particularly enumerated, will be clearly understood from the following de-' tailed description of the same.

The invention is clearly illustrated in the accompanying drawings, in which Figure l is a diagrammatic perspective of a length of tubular knit metallic fabric, out of which the scouring device is to be made, said view showing the manner of dividing the material by a restrictive binding to provide two sections, from one of which is to be formed the core or center mass, and from'the other of which is to be formed the exterior' cover or encasing portion; Figure 2 1s a fragmentary part side elevation and part longitudinal section, taken on line 2-2 in said Figure 1; Figure 3 is a view similar to that shown in Figure 1, but illustrating one section of the material balled together to provide the core or center mass of the device; Figure 4 is a part side elevation and part longitudinal section, taken on line 4 4 in said Figure 3; Figure 5 is a view similar to Figure 4 but showing one section of the Y material doubled back on itself preparatory to forming a plural ply exterior cover or encasing portion; and Figure'G is a partv elevation and part section of the completed device, the dotted lines indicating the manner in which the plural ply cover or encasing portion is manipulated to cover the center or core of the device.

Figure 7 is a view similar to that shown in Figure, but illustrating a modified pre paratory arrangement'. of the cover or encasing portion; and Figure 8 is a part elevation and part section of the completed device, the dotted lines indicating the manner in which the4 plural ply cover or encasing portion is manipulated to cover the center or core of the device.

Figure 9 is a part elevation and part section of the novel device illustrating another modified arrangement of the plural ply cover or encasing portion. p i

Similar characters of reference are employed in all of the hereinabove described views, to indicate corresponding parts.

The novel scouring device is preferably constructed from a tubular knit seamless abrasive fabric joined into initial tubulal 'l'orlu by a seam may be employed il'desired.

The fabric may be all metal, that is one `formed entirely from metallic material,

preferably of a non-corrosive metal, suchV as copper, and preferably from a thin ribbonlike or flat wire, although other cross-sectional shapes of wire maybe employed; or the fabric may be made of vegetable yarn and metal in any suitable manner to produce an abrasive fabric of composite character.

In making up the novel form of scouiing device, which is the subject of this invention, I take, preferably, a suitable length of tubular fabric, and consti-ict the saine intermediate itsends'by a tie 11 of wire or other suitable material, to thus provide two sections. I thereupon ball together into a roughly spherical or spheroidal mass one section of the material, to thereby provide a spongiform-yieldable center mass or core12 (see Figure 3). Having thus formed the center mass or core, I thereupon turn or fold back the remaining section over and around the center mass or core to envelop the same with a continuous cover 13 suitably fastened in place. It is preferable to so form the cover section that l it consists of a lurality of plies or layers, and to this endp said cover section is first turned or folded back upon itself, -to provide a two-ply tubular portion comprising the plies or layers 13 (see Figures 4 and 5).

' The two-ply tubular portion is thereupon A 111g means.

turned downwardly and outwardly around the center mass or core 12 in the manner indicated by the dotted lines in Figure 6, and the free edges, of the two-ply tubular portion are then gathered together and secured at the opposite vor free side of the center mass or core 12 by wire or other stitches 14, or by any other suitable fasten- As a result of the above described' operations, the two ply tubular portion is caused to entirely envelop the loosely balled up center mass or core 12 so as to provide, in this instance, a double cover or encasing portio-n or member 13, as shown by the solid lines in said Figure 6, thus coinplctino the novel scouring device. It will be quite evident that the .scouring device, formed -as above described, provides Ia spongiform yieldable abrasive spheroid mass, which is readily adapted to conform to the surface against which it is applied vto produce deleterious effects.

and rubbed; which is comfortable to use or handle; and which by reason of its splinterless character will not shed particles or splinters of metal, likely to enter the fingers of the user, or lodge in cooking utensils and thus find their way into food which is taken into the human system, and thus vbe likely abrasivemass is encased in a cover portion formed, preferably, of a plurality of pliesI or layers, the article is of a very durable character, and will long retain its shape Since the a in use. Even after considerable wear opens up, more or less, the outer ply or layer of the cover portion, the inner ply or layer thereof will still retain the center mass or vpractical life of the device' considerablylengthened.

In Figure 6 I have shown the cover portion as formed to provide two plies or layers of encasing material, it will be understood, however, that it is quite within the scope and principles of this invention to construct the cover portion so as to provide more than two plies or layers, if it is so desired. For example, in Figures 7 andS I have shown the cover section folded and refolded upon itself in such a manner, that three plies or layers 13 are provided to encase or .surround the center mass` or cover 12.

I do not limit myself to the particular methods of interfolding upon itself the section ofy fabric from which the cover portion is formed as shown in yFigures 1 to 8 inclusive, for any manner of folding the material may be employed to produce a. cover portion comprised of a plurality of plies'v or layers. For example, in Figure 9 I have shown another method of folding the cover section, to wit, by first turning the same over the center mass or core 12 in one direction to form an inner cover portion 15, securing the saine by the tie 16, and then turning the remaining portion back in the opposite direction to form an outer coverportion 17, the free edges of which are secured by the tie or stitching 18.

While I have shown the center mass or core 12 as an integral part of the initial piece of abrasive fabric, it .will be understood that I do not limit myself to such form, for the core or center mass maybe formed of separate material, and then enclosed by the cover of the tubular fabric interfolded upon itself in the general manner above indicated.

Having thus .described my present invention, I claim:-

1. A scouring ball, comprising a knitted metallic fabric, a portion of said fabric bei section being balled together to vform a A spheroidal spongiform center core, andthe other section being folded around said cen-v ter core with the end secured to form a continuous enveloping outervcover portion.

3. A scouring ball, comprising a tubular abrasive fabric restricted atan intermediate l portion to divide the saine into two sections,

one section being balled together to form a substantially spherical center core, and the Vother section being `.doubled upon itself and then folded around said center core with the end secured to form a continuous enveloping outer cover portion consisting of aplurality of layers of said abrasive fabric.

' In testimony, that I claim the invention set forth above I have hereunto set my hand this 15th day of May 1924.
