u. w. ANDERSON CLEANING PAD Filed July 26, 1959 M/VE/VTOR By John Ml. Anderson ATTORNEY FIG. 5

Patented Sept. 9, 1941 2,255,497 CLEANING PAD John W. Anderson, Gary,lnd., asslgnor to Productlve Inventions, Inc., a corporation of Indiana Application July 26, 1939, Serial No. 286,504

. 2Claiins.

My invention relates to cleaning pads and more particularly to scouring pads especially adapted for cleaning flat surfaces such as windows and Windshields. I

In cleaning glass, particularly Windshields of automobiles, it is desirable to provide a scouring pad which has two relatively flat surfaces, one of which may comprise 'a fabric and the other of which preferably comprises a metal wool covered surface. Metal wool has previously been suggested for use in removing insects and foreign matter from Windshields, but this generally has not been successful because of the shape of the material and because the material generally has been so harsh as to injure the finish of the automobile adjacent to the windshield, particularly the metal rim of the windshield. It furthermore would be desirable if in conjunction with metal wool it were possible to utilize water or a liquid cleaning agent.

It is an object of my invention, therefore, to provide an improved scouring pad suitable for cleaning windows and Windshields which will overcome the above mentioned disadvantages of the arrangement of the prior art, and which will be simple and reliable in operation.

A further object of my invention is to provide an improved method of manufacture of a scouring pad of the type referred to above.

Another object of my invention is to provide an improved scouring pad for glass surfaces and the like which can be used against frames adjacent to said surfaces without exposing such frames to the scouring action of the most abrasive portion of the surface of said pad.

Still another object of my invention is to provide an improved scouring pad adapted tohold metal wool on its surface with a minimum of tendency of the wool to break and detach itself from the pad. v

The novel features which are believed to be characteristic of my invention are set forth withtaching or securing the metal wool to the fabric covering of the securing pad.

Referring more particularly to Fig. 1, I have shown therein my improved scouring pad I B which preferably has the shape of a quadrangular prism, the outer surface of which is constructed of two. pieces of fabrics II and IL. The upper fabric 12 is provided with metal wool l3 which covers a substantial portion of one of the larger surfaces of the pad. Preferably this metal wool should be a metal wool which has sufllcient abrasive action when in use to remove insects and foreign matter from automobile Windshields, yet it should be sumciently fine in texture and not harsh so that the metal finish of the windshield frame will not be injured. It has been found that annealed bronze wool is satisfactory for this purpose. The metal wool surface of the scouring pad 40, when used with water or a liquid cleaning agent quickly and readily removes insects and foreign matter from the windshield.

The shape of the fabric covering of the scouring pad HI is maintained by a quadrangular prism of resilient foraminous material H shown in the cross sectional view of Fig. 2. One form of foraminous material which has been found to be satisfactory is sponge rubber, although it will be apparent that other materials may be used. The use of a foraminous material on the interior of the cleaning pad 10 permits a certain amount of water to besupplied to the metal wool surface l3 of the pad during the cleaning operation. The foraminous material furthermore permits a certain amount of moisture to be supplied to the fabric surface ll so that when the pad is used for applying a cleaning agent in cake or powder form a certain amount of cleaning agent will adhere to-this surface and additional water will be supplied to this fabric portion of the pad during the cleaning operation.

In the process of-manufacturing the cleaning pad l0 suitable fabric such as I! is cut into strips.

having a width indicated as A in Fig. 3. Strips of annealed metal wool, such as for example ann'ealed bronze wool, are then placed upon the strips of fabric and the metal wool is then stitched, at suitable intervals such as the intervals' B shown in Fig. in the same direction as the general direction of the fibers of the metal and these rectangles are then fed into a multineedle sewing machine so as to stitch the wool in a direction substantially at right angles to the previous stitching, as will be apparent from Fig.

wool. The strips of fabric with a strip of metal wool stitched thereon are then cut into rectangles 1. Preferably, the latter series of stitches should be separated by a smaller interval such as C.

Another piece of similarly shaped cloth is then joined at three edges thereof to the fabric having metal wool stitched thereon so as to form an envelope. A quadrangular prism of resilient foraminous material is then inserted within the envelope and the envelope is closed by stitching the remaining side. This produces a quadrangular prism-shaped scouring pad having a fine abrasive metal wool on one surface and a plain fabric on the other surface of the pad which may be saturated with water or a liquid cleaning agent thereby producing a simple device which is reliable and efficient in operation.

While I have shown and described my invention in connection with a certain specific embodi ment, it will, of course, be understood that I do not wish to be limited thereto, since it is apparent that modifications may be made in the embodiment and the materials thereof without departing from the spirit and scope of my invention as set forth in the appended claims.

What I claim as new and desire to secure by Letters Patent of the United States is:

prism of resilient foraminous material, said prism 'fitting porous fabric, and annealed metal wool covering laterally a substantial central portion of one of the larger surfaces of said fabric, said wool having its fibers generally arranged in one direction and being secured to said fabric by stitching said wool at certain intervals in the general direction of the fibers of said wool and also at smaller intervals at substantially right angles to the general direction of the fibers of said wool.

2. A scouring pad comprising a quadrangular prism of resilient foraminous material surrounded by a plurality of pieces of porous fabric forming a close-fitting cover, said prism having two surfaces of larger area than the remaining surfaces and annealed bronze metal wool covering laterally a substantial portion of one of the larger surfaces of said fabric so as to provide two non-abrasive edges, said wool being secured to said fabric by stitching said wool at certain intervals in the general direction of the fibers of said wool and also at smaller intervals at substantially right angles to the general direction of the fibers of said wool.
