CORPORATION or MASSACHUSETTS MATERIAL FOR SCQTIRING UTENSILS Application filed December 4, 1930. Serial No. 500,022.

This invention relates to an improved arrangement of material for scouring utensils. A particular utensil 'in which the new material can be used to advantage is shown in my copending application Serial Number 474,- 551, filed Augutt 11, 1930, i

In utensils of'this'general character, the common practice has been to use a textile carrier, cord on which a flattened metallic filament is twisted. The twisted or gimped filament provides scouring edges. My invention consists in changing the character of the carrier around which the metallic filament is twisted. In one form of the invention I use the same kind of filament for the carrier as is used for the element twisted about the carrier. To increase the effectof this change I may use two or more such filaments inste'ad of one for the carrier means and twist one or more filaments about the carrier means. The latter combination gives-a loose bundled arrangement of the carrier filaments which are not twisted to carry the filament or filaments which are twisted. By the new combination more scouring edges are provided than in the old, and other advantages are obtained as will be pointed out with respect to the utility of a scouring utensil with the new arrangement of material.

A complete understanding of the invention is given by the accompanying drawings and description of the advantages in the new combination. In the drawings- Fig. 1 is a plan and Fig. 2 is an end view of the carrier means in multiple form;

.--.Fig. 3 is a View of the carrier filament with another filament of like character twisted about it into gimped form; and

Fig. 4 is a view of a scouring utensil such as is made up from the material shown in Fig. 3.

The filament 1 is or may be made of copgiven an anti-rust treatmentor is made of an anti-rust alloy. It is such a filament as has been used ordinarily for the twisted part of the made-up strand in a scouring utensil of my type, but may differ by providing a stronger filament. As a modification I may rier filaments break, but the latter 'will function to scour in any event. T 0 practice my new invention I use a single filament 1 or a plurality of them, as shown in Fig. 2, as the carrier, and twist about it coils 2'of another filament of about the same kind. But the filaments 1 and 2 are all flattened so as to present scouring edges. The carrier 1, while it is not purposely. twisted, may nevertheless turn somewhat. The gimped or twisted strand 2 is loosely mounted. on the carrier 1 with many turns to the inclrabout carrier 1 to increase the scouring edges.

When the combination of Fig. 3 is used in a scouring utensil the coils of strand 2 being loose are spread apart and pushed together, due to the rubbing action. When they spread apart the edges of metallic strand or strands 1 occupy the space between and are in a position. to function also as a scouring element and as a scraping element at the points where the coils have separated widely.

In a scouring utensil such as shown in Fig. 4 the total effective scouring surface is greatly increased by the new arrangement or combination of material .making up the utensil.

-'And this would be true also if other specific forms of scouring utensils were made up of the new arrangement of material.

The utensil shown in Fig. 4 is made up except for the material of the carrier cord like the one more fully described in the above referred to'copendmg case. That is, the combination of carrier filament 1 and coiled filament 2, as shown in Fig. 3, is looped into skein form. Each skein loop passes twice through two circular binding'elements 4 and 5. By arranging the binding elements 4.- and 5 at directly opposite points in the skein loops, the material of theskein between the binding elements is left in loose but regularly arranged form. The result of such arrangement with the material shown is like a puff ball. The efiect is improved by the character of the carrier filament. There is 'ust enough spring in the metallic carrier to e ect a better holding of or return to the puff ball shape after use. In other words,'the carrier 6 filament makes the utensil just a little stifier in form and yet yieldable enough for its function. The filaments which carry the gimped strands can and do act as scouring and scraping elements where the gimped strand is 10 moved along orspread out. Furthermore,

the bright appearance of the ball when made entirely of flattened filament is enhanced. The binding elements t and 5 are preferably of stiff wire so the whole utensil is of metal but in form to be easilyoleaned.

\Vhat I claim is: 1. The combination for scouring purposes of twofiattened metallic filaments, one arranged as a straight strand for carrying the other and the latter loosely coiled or gimped about the first so that the combined all-metal strand has scraping edges throughout its length, some on the "carrier strand and some on the gimped strand. 2. An improved structure for scouring purposes of a plurality of loosely arranged parallel flattened metallic filaments in untwisted form and providing a carrier means, a metallic filament loosely twisted or gimped about the carrier means to make with the carrier a composite scouring strand in which scouring edges are provided by both the carrier and the gimped elements.

In testimony whereof I have affixed my signature.
