Application l'ed June 24, 1924. i Serial No. 721,970.

Cleaning pads of fibrous material as, for instance, wool7 particularly steel wool, are commonly used in combination with soap. In jfact, packages of steel wool scouring pads as commonly marketed for many years past have included a cake of soap for use in combination with the pad, I have observed that when these cakes of soap are used between two of the pads, the steel wool tends to embed itself in the soap, but I find that an ordinary cake of soap is likel to be too y thick for convenient use in suc relation;

moreover, its size and weight are such that the embedding is seldom sufficient to make a bond secure enough for practical purposes,

when the article is in prolonged use and my present invention contemplates a practically permanent association of the soap with the steel wool in an article comprising a number of'thin sheets of soap interleaved between a plurality of steel wool layers or pads, the steel wool embedding itself in the soap and the composite article being supplied about part of its surface, with la binder. Such binder may be somewhat like the binding of a book covering an edge and part of two faces of the composite article, l

or it may be in the nature of a band for binding layers together. In an case, the article ispreferably used with-t e exposed edges of the leaves of soap and of steel wool applied to the article to be cleansed.

Certain embodiments of my invention will be readily understood from the following description'in connection with the accompanying drawings, in which Fig, l is a perspective view showing one embodiment of my invention;

Fig. 2 is an end elevation showing a modification;

Fig. 3 is a perspective View showing another modilication; I

Fig. 4 is an end elevation showing another modification; and

Fig, 5 is a similar View of a further modification.

In Fig. 1v thin sheets of soap 1, 1, etc., are shown as interleaved between the more or edges of the layers to the article, that is, the

surface edges lowermost in Figs. 1 and 2. In. F ig, l I have indicated that the binding/1s secured by waterproof cement such as rubber cement and the ends of the leaves embraced by the binding, but not engaged thereby, may be secured by a coating of rubber cement 4. Such waterproof cement may be used as the sole binding for the article, the binding sheet 3 being omitted.`

In Fig. 4 I have shown a modification wherein the arrangement of thel soap and steel wool layers may be substantially the same as Fig. l, but the binding 4 consists of a material which is carried around the side edges of the pad as well as across the back and down theside. Such bindings may be tin foil or sheet lead.

Fig. 3` shows a modification in which a single soap sheet 1a and a single sheet of steel wool 2a is rolled up in a s iral, unrolling being prevented by a bin er 3 which may be either a cup or a band and may consist of fabric or of tinfoil or may be merely a coating of the waterproof cement.

Fig. 4: shows another modication in which'a core ofmetal wool 11 has wound around it a cylindricalsheet of soap 12 about which is a cylindrical layer of metal wool 11a about which is a second lindrical sheet of soap 12B. Outside of the atter and forming the outermost layer, is a final sheet of metal wool 12b.

vAs indicated in Fig. 5, the spiral arrange# ment-of Fig. 3 may be flattened down to an oval or rectangular Vpad if desired. The

same attening may be practised with theconcen'tric arrangement of Fig. 4.

that the center or core ofthe cylinder isof metal wool, which I find to be a distinct advantage over having a core of soap. One reason is that where the soap is concentrated in a central core, the metal wool is a t to strip backward and expose the core. If the latter is stiff enough to endure in such a situation, it -requires more soap than is lno likely to be needed in connection with and during the life of that particular pad. With my arrangement, the soap is in delinite quantity, definitely arranged and in general is likely to wear back or bendor pack or become upset into and between the steel wool layers, under the conditions of use. It will be understood that in practice the pad will wear down and flatten out and that eventually portions of the binding or cover may be torn oil or stripped back until the entire pad has been used up.

The form shown in Fig. 1, when used in the manner described, is likely to open up and flatten down and can be used up as completely as the ordinary ad.

ln many cases it will be ound thatcollodion is a very satisfactory cement to be used either itself as a covering or as a means for securing the fabric or metal coverings.

1. scourin ad comprising a com ite llaminated',gbdy formedV of ,relatiggly thick layers of matted metal. wool alternating with relatively thin layers of soap.

2. A scouring pad comprising a composite laminated body formed of relatively thick layers of matted metal wool alternating with relatively thin layers of soap, and a binding for securing the layers, said binding extending across the back edges of said' layers and part way over the exterior layers.
