' v10min. 11.15440 ticles generally, especially to cleaners used for scrubbing or cleaning greasy or extremely dirty therein so that the entire cleaning action is due to the abrasive action of the metallic wool. lf

soap or water is to be used in cleaningthe article, then an ordinaryrag or brush is used to removel the dirt or grease from the article. No cleaning article'upon the market today has efiectively combined an abrasive cleaning action-` rwith the use of .an emulsifying or cleaning agent,

such as soap.

vThe general Vobject of the'present inventionis to provide an improvedvcleaning article which is adapted to combine both an abrasive and 'an on `the article to be cleaned. Y

- A further object of the present inventionv is to provide a tough but resilient cleaningl article which has a long life. z

A further object oi the invention is to provide a novel cleaning article iromrcellular rubber and abrasive material.

The foregoing andother objects will be manifest from the accompanying speciiication'. reference being had of which: Figure 1 is a' transverse section of a cleaning article embodying the. invention, and a mold in which the articles are formed: and

Figures 2 and 3 are fragmentary detailsectional views. on Va larger scale, of other embodiments oi `the invention.

In the drawing-a cleaner or cleaning article Il is shown, which article mainly comprises cel- T .i oFFICE is used te provide tneeruele In with an abrasive material Ifor removing grease o`r-large particles of dirt from an"article to be cleaned. The clean ing action oi the abrasive, stainless steel wool,

is aided by'soap and water which ordinarily will be used in conjunction with the cleaning article and which will be carried inthe cellular rubber. Hence, two types of a cleaning' action are combined by the use ofthe cleaning article of the invention, whereasy such combination hasnot been possible when using types of cleaners heretofore available.

The article I0 is made -in a suitable mold I6,-

the moldingcavity of which is first provided with a layer or skin of rubber, or rubber-like substance by pouring a dispersion of such substance into the 'mold and depositing a layer on the-mold surface. The excess dispersion is then removed` from the mold and stainless steel wool, which may be formed. to substantially the shape desired, is introduced into the mold. Then before the gel oi rubber, or rubber like material is completely set up, aerated latex is poured into the mold and itilows around and illls up the space between the particles of stainless steel wool.

. Lastly the-latex is gelled and vulcanized to proto the accompanying drawing lular rubber Il, which has-intercommunicating cells and preferablyv is made directly from latex by beating and/or aerating same to form cellular rubber therefrom in accordance wlth'well known practice. The cellular rubber Il may be provided with a base l2 and witha base ilange Il.

. A dense rubber skin 4I4 extends yover the sides and 'base of the cellular rubber body II. The cleaning article." also includes a mass' ot stainless steel wool I5 which4 is embedded in the ycellular rubber I I and which is made from a very soit, or annealed stainless steel. The stainless steel wool with the disclosure inmy copending application ySerial No. 370.791, illed December 19,1940;-

A modiiled cleaning article Ita, substantially the same as the article Il, is shown in Figure 2.

4The article Illa has an impervious skin Ila thereon 'formed around a cellular rubber core lla and `.has stainless steel wool Ila. embedded therein. The cleaning action of the article Ila is enhanced by abrasive particles II.` such "as pumice, which are embedded therein. -The abrasive.. particlesshould be compounded in with the latex used in tormingthe 'cellular rubber lla and in all events, are distributed through the cellular rubber .to provide a somewhat diiierent cleaning action from that obtained solely by use o! stainless steel wool. A cleaning article. IIb, which has no impervious surface skinthereon but which otherwise is identical with the cleaning article il, il shown in `3, which cleaning article may bemost suitable for some purposes. In a further modification ot the invention, a cleaner may bcmade'solely trom cellular rubber which has an impervious skin over a portion of the cleaner. Y v

It will be seen that a cleaning article having a waterproof yet ilexible covering over most of its surface is provided by the invention; Hence, the cleaner can be used by a person without getting the users hands wet. Also, the soap or other cleaningagent is only applied to one surface of the article whereby a savings is effected.. Use of an oil and grease4 resistant rubber is especially desirable where the article is to be used in cleanv from the scope of the invention as have been completely illustrated and described herein, it will be appreciated that further modifications thereof may be made without departing appended claim. P

What is claimed is:4 v

A scrubbing cleaning article comprising a body of intercommunicating cellular rubber, and abrasive niean's comprising a mass of soft, annealed stainless steel wool embedded in and extending through said body to reinforce the same and en- "hancethe cleansing action thereof, the body having a base portion, side portions and an exposed end portion, an impervious skin of a exible material bonded rto said base portion and side portions, and said body having a base ange, whereby the article is adapted to be held comfortably in the hand of a user.
