This invention relates. to an improvedconstruction of scouring device in the form of a hand implement which is especially adapted to provide a mild abradant for scraping, cleaning and polishing the surfaces of utensils and other surfaces desired to be so treated.

H The invention has for its principal object to provide a novel construction of device adapted to furnish an abrasive mass made of metallic wire or a composite of metallic wire and vegetable yarn so fabricated as to furnish a multiplicity of closely associated abrasive" members or elements rigidly se cured at their inner ends to an interior core and radiating therefrom, to thereby produce the desired shape effectively retained against shredding, pulling out,

' sloughing off, and against other permanent deformation from its desired more or less compact initial shape; the device so made is readily conformable-by pressure, however, to the surface to which it may be applied in use, while at the same time it provides a great multiplicity of scraping edges adapted for operative contact with such surface when pressed against and rubbed over the same.

The invention has for a further object to provide an interior binding and carrying core for the abrasive material which may be extended to form or receive the attachment of a suitable handle member.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is'a perspective view illustrating a step in the fabrication of the novel scouring device of this invention;

In order to more'clearly illustrate the essentialcharacteristics of the finished article embodying the construction and principles of the instant invention, there is shown in the drawings, in somewhat diagrammatic fashion, certain steps, by which the article maybe produced. The article is essentially made of metallic material, preferably in the form of flat ribbon-like wire or wire of angular cross sectional shape which is turned or twisted upon itself to provide a roughly spirally convolved strand or otherwlse deformed to provide a multiplicity of lateral, scraping edge projections or points; ,or the strand or length of material may consist in a flexible carrying core of straight wire or vegetable yarn upon which is earned the spirally convolved or gimped flat metallic wire or wire of angular cross-sectional shape adapted to provide a multiplicity of lateral scraping edge projections or points, as shown, e. g. in Figu metallic material employed is of a relatively non-corrosive character; for example copper may be used, both for its relatively non-corrosive character as well as for its comparatively hard nature, whereby its scraping or abrading functions arerendered more efiiv cient. 1

re 1. Preferably the In making up or assembling any of the forms of metallic material above mentioned to fabricate the same into the novel construction embodying the scouring device ac--.

cording to the principles of this invention, a supporting bar 1 isvutilized and a suitable length of the metallic material is wound in a multiplicity of adjacent loops 2 along the len h of this bar. Each of the loops 2 has one of its bights 3 extending around and in engagementwith substantiallypne half of the circumference of the bar 1 while its other bight 4 hangs freely. The bar '1 supporting the loop 2 is then bent upon itself, as illustrated in Fig. 2, to form a U-shaped member having the loops 2 extending along both legs 5 and 6 and along the bottom of the U of this member. This causes the bights 3 of the loops 2 that extend along one of the legs of the U-shaped member to be brought into abutting relation with the similar bights of the loops 2 extending along the other leg of the U-shaped member. The bottom of the U is then held stationary by a suitable clamping device and the free 7 member and causes the legs to be .twisted tightly uponone another as illustrated in Figure 3.. The bights 3 of the loops 2 are I securely gripped between the twisted legs of the U-shaped member and, owing to the large angle of wrap of these bights about the legs 5 and 6, such bights cannot be pulled from between the legs 5 and 6. A

portion of the member formed by the twisting of legs 5 and 6 is then bent into substantially circular form as illustrated in Fig. 5 to provide a core 8 having a shank 10.

- It will be noted from an inspection of Fig.

5 that the loops 2 at one side of the core 8 are entirely inde endent from and are not continuations o loops on the opposite side of the core. This is important for there is no possibility of a side of a loop pulling through from one side of the core 8 to the other side thereof. Also, since the loops 2 on opposite sides of. the core 8 are independent, should the loops on one sidewear and become broken oil at the core, such wearing will not afi'ect thestrength or wearin qualities of the loops on the opposite si e of the core 8 This would not be true were the loops on opposite sides of the core but continuations of oneanother for in that case, since the angle of wrap of such loops upon the legs 5 and 6 would be slight, there would be nothing to revent the loose woven ends from-pulling t rough-in practice and causing the useful loops on the opposite side of the core to drop out, thereby shortening the hfe ofbthe scouring device considerably.

The shank 10 is'adapted to be extended itself to provide a hand e member, or it may be inserted into and frictionally retained within a recess-in a separzg: handle 11. If

desired, the shank 10 ma assed throu h the loop 7, as illustrate in ig. 8, there y being looped upon a supporting member or bar 1 to provide a plurality of loops, each of said loops having one of its bights wrapped substantially 180 degrees around the bar 1 and its other bight free; said bar being bent upon itself and twisted to thereby pinch and rigidly secure the inner wrapped bights of the loops to the bent and twisted bar, whereupon the bar is bent to form a core having a shank for insertion into a handle. The loops radiate outwardl from this core and as these loops are- 0 substantially equal length, the resultant article'will preferably possess an ellipsoidal contour, and .yet, since the bi hts 4 are free, a very pliable and con formalile mass is provided which retains its shape in use without tendency to shredding, sloughing, and without tendency to become attenuated or lose its generally ellipsoidal conformation- At the same time, the body so formed and constructed readil flattens itself against a surface to which it 15 applied and over which it is rubbed; a multiplicity of the scraping edge projections 12 acting to efliciently attack the surface so as to quickly remove dirt, en'erustations, grease or the like therefrom b the cleansing or scouring abrasion thus a orded.

A very advantageous form of the novel scourin device structure isv produced when:

made 0 material such as shown in the draw ing wherein a carrying strand or core 13 of flexible wire or of vegetable yarn is provided with a gimping of preferably flat metallic wire to form a multiplicity of:

lateral scraping edge projections 12. The strand or core 13\ serves to retain the radiating loops '2 against unduestretching or elongation.

From the above description it will be apparent that a unique and yet very eflicient scouring device is provided, which is easy to handle and readily functions to conform itself to a surface upon which it is rubbed;

.and furthermore the novel retained relationestablished between the carrying core, and the abrasivqstrandsassures that the article will withstandtherough usage which is inherent in the purposes it is intended to serve, without risk of undue deformation, apart or similar displacement of the abrasive strands of which it is com osed.

fAs many changes coul be made in the above construction and many apparently widely diflerent embodiments of this invention could be made. without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
