Application filed September 4,1925. Serial. No. 54,4.00.

My present invention relates more particularly topads of the type used for cleaning and scouring metal and other surfaces, particularly aluminum and other household utensils.

Proper cleaning of such metals, particularly of kitchen utensils usually requires removing a certain amount of grease and dirt and also removal of the minute film of oxide or tarnish that clings to and usually forms part of the metal. The removal of the dirt is facilitated by soap and water but is suppletheir shape upon use, and thereby lose their efiectiveness. and convenience. They tend, moreover to disintegrate into irregular portions of metal wool, and in so doing become hard to handle, and render possible injury to the hands because of loose or flying fibres which may twist about the fingers and pos: sibly cut them.

mMy present invention contemplates a pad in which the fine mechanical abradant, that is, the metalwool is employed in close as sociation with a coarser metallic holding means preferably in the form of a metal fabric enclosing the metal wool.

. By having metal fabric in which the openings in the mesh are of sufiicient size, I may provide a holder having openings through V which the metal wool. can bulge suficiently to perform its film removing and polishing function.

cleaning pad, I preferably enclose therein pieces of soap, preferably enclosing them likely to be broken up or escape through the I .50

within the steel wool so thatthey will be less meshes of the fabrid A very important and preferred embodi ment of my inventionconcerns the use of copper ribbon for the scraper fabric in combina- To assist the grease removing action of the the ribbon loops 0 The metal fabric envelope may be secured about the metal wool in any desired Way. A

cheap and attractive way is to have the envelope of thmflexible copper ribbons made on a stocking knitting machine, since this permits extreme lateralor endwise distortion of the fabric because of the looped structure and the slippery, springy quality of the metal rlbbon.

This or any other-suitable fabric may be formed as a tube, the metal wool and soap inserted therein, the ends of the tube closed I and folded-over and secured together by wire or other suitable fastening means, and the whole flattened and formedto standard size in a suitable press. This has the advantage that one face of the pad hasa large part of 1t s effective working surface comprised of metal wool, but provided also with-acertain amount of scraping ribbon which will be afforded by the enclosing fabric even thou h the latter be very open and considerably stretched. The reverse or folded-over side is abradant metal .wool.

Y in order to still further increase this protection tothehand I may insert one or more layers of woven wire cloth of fine mesh inthe stockin just under the folded-over side and may W ile' making the stocking change the mesh, as 1s well known in the art, soas to We arelatively large meshon-the side which 1s to contact with thearticle being cleaned,

and a, relatively fine mesh on vthe side to be in contact with the hand.

The above and other features of my invention will be more evident from the following description in connection with the accompanying drawings, in which Fig. 1,-is a view of the open mesh face of the pad; 1

Fig. 2 is a section on the line 22, Fig. 1; Fig. 3 is a view like Fig. 1 but showing the extended ends of the metal envelope before thiy are folded over. ig. 4 is similar to Fig. 3 but showing the "ends of the fabric gathered together andse- {cured 1n osition.

. Fig. 5 1s a view indicating in detail and on.

the hitted .fabric.-

In these drawings the metal wool 1 is shown."

as enclosed in an envelope of metallic fabric 2. This fabric may be of wire as it ap ears to be in Figs. 1 to 4 and such wire may e of any desired cross-section and the weave or knit of the fabric is as indicated 1n Flg. 5..

' the fabric, by reason of the loop structure in combination with the springiness and ribbon shape of the metal, a characteristic relation shown in Fig. 5 is where the fabrlc is somewhat stretched so that the ribbon erztends zigzag and comprises more or less aligned portions 3 that are likely to be more or less curved. By reason'of their length and tension these portions are apt to lie more or less flatwise in the surface of the fabric, as shown. Intermediate the portions 3, theribbon extends lengthwise'of the fabric inloops comprising legs 4, 5, which are apt. to be partly flat and partly edgewise and these are connected by intermediate curved portions 6, that are apt to be edgewise. Through the of each loop 5 is looped in the loop 4, 5,

in of an adjacent strand of ribbon, while the base of the loop is encircled by the loop portion ofthe other adjacent strand.

As shown the fabric is supposed to be somewhat tensed so that the strands and loops are in fairly definite positions and in practice many portions of the fabric will have the ribbon presented edgewise so that the whole structure is adapted to afford a multiplicity of non-abrasive scrapers well adapted for scraping and loosening grease and dirt wlthout becoming clogged. x

Thereticulations or open spaces 7 y are of suchsize that when'the fabric" is stretched as shown in the drawings, there is ample 'room for exposure of the soft springy metal wool. 4

As soa and water are always applied by .these pa s I have shown in Fig. 2, cakes or pieces of soap 8 enclosed. in the fabric, prefthefabnc. y

As shown in Fig. 3 the metal fabric envelope 2 may be in the form of a cylinder or tube considerably.longer than the pad 1 and .the article may be completed merely by gath- In this condition the surface shown in Fig.1

affords a heavy layer of fabric protecting the hand'from'contact with the wool when the face shown in Fig. 1 is to be pressed against the work. The other face shown in Fig. 4

of knitted metal strands. erably in the steel wool, so that they will be a less likely totear or fall through the mesh of is mostly scra er surface because the numeroussu erpose puckered and flattened layers of ,iib n fabr1c practically cover up and mask the underlying metal wool. The copper surface being less apt to clog or become matted is best for use on thick soft grease while the opposite metal wool surface is best for polishin The face of the metal wool which'is shown in Figure 4; may be further protected from possible contact with the hand by insertion of a layer of woven fire fabric 10, as shown in Figure 2. It will be understood in all cases it is possible for the user toslip the fingers under the overlapped end of the fabr10 2, so that the article ecomes in effect a padded mitten in which the fingers of the user may be protected from the steel wool by-the above described Wire fabric.

The material forming the open mesh fab-' or electro-chemical action, probably due to the cogper in contact with the steel wool, has the e raw cut surfaces of wool. The darkened bluish steel wool furnishes an artistic attrac-- tive and harmonious background for the copper ribbon net work by which it is covered. Althoughthe body of the pad is preferably of steel wool, it may be of copper wool and: enclosed by aluminum or cop er fabric.

One advantage of forming the abric covect of darkening. and givinga .blue' tinge to the steel .wool, which is ordinarily an unattractive, cold, gray, characteristic of ering as a tube with the ends folded over and fastened together, is that it enables the fingers to be. placed within the pocket formed between the connected ends of the covering and the main body of'the pad.

I claim 1. A pad including a body of steel wool:

and a surface covering of copper ribbon fabrm. f i

5. A pad comprising a mass of metal wool enclosed in an envelorie' of open-mesh fabric, the fabric being tubu ar and having the extended ends folded back and secured together on the same face of the pad to afford multiple layer covering for the W001.
