CONTR'IVANCE FOR CLEANING COOKING UTENSILS AND OTHER .AIRflIllC-EIS.l
To allwkom 1f/ may concern.'
Be it known that I, EDWIN M. GOLD- sMrrH, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Contrivances for Cleaning Cooking Utensils and other Articles, of which the following is a full, clear, and exact description, reference lbeing had to the accompanying drawings, which form a part of this specification.
y The object of my invention is to provide a cleaning contrivance adapted Vfor the removal from cooking utensils of dirt, grease and adhesive substances which resist relnoval by means of wash rags and soap and hot water. For this purpose the use of abrasive material, such as meta-l chains, or woven or knitted fabrics interwound with non-corrosive metal, such as copper thread, is known; but such devices, while effective so far as concerns their abrading fu-nctions, possess little or no absorbent properties and are therefore ineffective except when supplemented by independent treatment with wash rags.
The more specific object of my invention is to provide a cleaning contrivance which, when rubbed back and forthV over the surface to be cleaned, will, by frictional action, remove the material adhering to such surface and will also be effective to yabsorb the water which has dissolved, or which carries in suspension, the removed material, and wh-ich will be capable of removing both the material which resists removal by means of a non-abrasive rag and the material for the removal of which a non-abrasive rag or the like is best adapted.
The invention is capable of many different specific embodiments. As examples, I have shown in the drawings two preferred constructions which have been found effective in practical use.
Figures l and 2 are face views of such embodiments of my invention. l
The base of the fabric shown in Fig. 1 is a woven or knitted fabric a formed of relatively coarse threads spaced apart to form interstices of substantial size. The`r degree of closeness of the -weave is not an essential feature of the invention, but the use of a coarse open fabric is preferred. At intervals throughout a part of the surface are Specification ofL Letters Patent.

formed orifices b of a diameter substantially greater than the space between adjacent parallel threads, said orifices being reinforced around their edges to prevent fraying. Whether the fabric be woven or knitted, the designing of the fabric will be much facilitated by providing for a plurality of rows of orifices the orifices of each row being spaced apart at regular intervals, as shown. Such an arrangement of orifices, while non-essential, also facilitates the attachment of the abrasive material to the fabric, as is hereinafter explained. 7
I prefer to employ, as the abrasive material, a spira-l metal coil or coils c, as shown in Fig. l, or an ordinary link chain d, as shown in Fig. 2, although the invention is not limited specifically to coils or chains. In Fig. l, two continuous'or endless spiral coils are shown, each coil being interlaced with the fab-ric by extending it through adjacent orifices b and alternately from one face to the other, so that, in the finished article, an approximately equal length of coil overlies both faces. Y
In Fig. 2, three chains ai are interlaced with the fabric and extend along three para lel rows of ori'fices b, each chain extending alternately from one face to the other, the corresponding ends of the two outer chains being united to each other and to the corresponding end of the central chain so that` they form, in effect, one integral structure.
It is preferred tapply the abrasive agent to only a part of the fabric, the same being arranged preferably wholly or partly across the fabric midway between opposite edges, so that at least one third of the area of the entire fabric along each of said edges presents a wholly non-abrasive surface'. These portions of the fabric may be folded over the portion that is reinforced with abrasive materialso as to cover the latter and render the cleaning contrivance wholly non-abrasive. In the preferred form shown, even that part of the fabric with which the chains, coils or the like interlace has the larger part of its area uncovered, the chains or coils extending only along lines connecting adjacent orifices I). Hence, even that part of the fabric that is reinforced with abrasive material possesses considerable absorptive properties.
Nor do I mean, bythe use of the term textile material to exclude the employment of any other relatively thin and superficially extended base having absorbent and relatively non-abrasive properties.
Having now fully described my invention, what I claim and desire to protect by Letters Patent is:
1. A cleanin contrivance comprising an unsupported p iable piece of fabric a large part of the surface of which is uncovered, the uncovered part acting wholly as an absorbent, and abrasive material both positively secured to the fabric and so extending superficially over the remaining part of said surface as to leave a substantial portion of the abrasive section of the fabric uncovered, thereby providing a exible cleaning contrivance one -section Which is Wholly absorbent and another section which is both absorbent and abrasive.
2. A cleaning contrivance comprising a textile fabric provided with orifices other than the normal interstices between the threads of the fabric, and means, embodying abrasive material, engaging said holes and thereby held upon the surface of the fabric so as. to a'ord means for removal by frictional'abrasion of substances resistant to removal by relatively non-abrasive absorbent material.
3. A cleaning contrivance comprising a 40 textile fabric providedA with orifices and means interlacing with the fabric by extending through said orifices from one face of the fabric to the other, said means embodying abrasive material adapted to overlie A5 the face of the fabric.
4. A cleanin contrivance comprising a base of textile abric provided With orifices and a string of abraswe material interlacing with the orifices and extending therethrough from one face of the fabric to the other and extending also over both'faces of the fabrics from one orifice to another.
5. A cleanin contrivance comprising a base of textile fa sive metallic material carried thereby and distributed over a part only of its surface, a substantial part of the surface upon which the abrasive material is distributed being uncovered by the abrasive material and presenting a non-abrasive absorbent surface.
6. A cleaning contrivance comprising a base of textile fabric and strings of abrasive material attached to both faces of the fabric so as to leave uncovered substantial superficial areas of absorbent and relatively nonabrasive material.
In testimony of which invention, I have hereunto set my hand, at Philadelphia, Pa.,
on this 12th day of January, 1918.
