ATTORNEY CLEANING AND POLISHING PAPER AND METHOD OF MAKING SAME This invention relates generally to a metal cleaning and polishing sheet or towel and more particularly to a disposable sheet having two different types of metal cleaning ingredients on opposite surfaces for application to a metal article sequentially, to first clean the metal article and then to polish the metal article.

It is an object of this invention to provide a paper sheet that contains the ingredients necessary to both clean and polish an article made of metal, such as silver.

It is also an object of this invention to provide a towel that can be used to clean and polish an article made of metal without requiring the addition of any fluid or solid ingredient or subsequent washing of the polished article.

It is another object of this invention to provide a disposable towel that contains all of the ingredients required both to clean and polish an article made of metal.

It is still another object of this invention to provide a paper towel that is dry to the touch and contains all of the ingredients required both to clean and polish an article made of metal.

It is still another object of this invention to provide a towel that contains all of the ingredients required both to clean and polish an article made of metal and deposit an invisible film on the article which will retard oxidation.

It is an additional object of this invention to provide a towel that both cleans and polishes an article made of metal with self contained ingredients, the towel being economical to make and easy to use.

These and further objects and advantages of the present invention are achieved, in general, through the use of a multiply towel of paper, non-woven fabric or a combination of both, one surface of the assembled towel receiving a liquid containing a cleaning means and a polishing means, the top layer of the towel filtering out and holding the cleaning means in operative position and allowing the polishing means to pass through and spread throughout the bottom layer of the towel. An ingredient that retards oxidation and is invisible when applied to metal can also be included in the solution fed to the top layer of the towel, and this ingredient will also pass into and spread throughout the bottom layer of the towel.

The novel features that are considered characteristic of this invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and method of operation, as well as additional objects and advantages thereof, will best be understood from the following description when read in connection with the accompanying drawing, wherein:

FIG. 1 is a view in elevation showing the cleaning side of the composite cleaning and polishing towel with a corner of a part of the towel turned up to show the under layers;

FIG. 2 is a view in elevation showing the polishing side of the composite cleaning and polishing towel; and,

FIG. 3 is a view, in section, taken along the line 3-3 of FIG. 1.

Similar reference numerals refer to similar parts throughout the various views of the drawing.

Briefly, in this invention, a predetermined quantity of a nonaqueous liquid containing metal cleaning ingredients and metal polishing ingredients uniformly dispersed therein, is applied to one surface of a multilayer towel or sheet. The metal cleaning material is a fine abrasive powder and the metal polishing material is preferably a liquid. The towel can comprise two or more layers of material; a first layer that first receives the liquid containing the metal cleaning ingredients and metal polishing ingredients; and, a second layer that receives from the first layer the metal polishing ingredients; the metal cleaning ingredients having been trapped by the first layer of material. If desired, an ingredient that will adhere to the metal and form an invisible film to retard oxidation of the polished metal can be added to the liquid and be incorporated in the second layer.

Referring to FIG. 1, there is illustrated a multilayer towel in accordance with the principles of this invention. The towel 10 can be made up of two or three separate sheets in superimposed position. Three sheets are illustrated. The first sheet or layer 12 can be composed of paper or a non-woven type of material made of rayon and fibrous materials or the like. The first sheet 12 is the cleaning part of the towel and, therefore, the first sheet should be of a relatively strong material which resists tearing when the metal is rubbed to remove any tarnish that is present. The second sheet 14 and third sheet 16 make up the polishing portion of the towel and ordinarily do not experience hard rubbing. Therefore, the second and third sheets can be composed of light, absorbent material, which is relatively inexpensive, such as tissue paper or two ply wet strength facial type of material in which is uniformly distributed the liquid containing the polishing ingredients.

The three layers are joined together either along the two side edges 18, 20; or entirely around the border edge, by embossing, overcast stitching or adhesive. The use of embossing to bind the various layers together to form a unitary towel structure is desirable as embossing does not materially alter the pliability of the towel, nor present threads which can catch or snag on irregular and sharp projecting surfaces and is adaptable for mass production of the different layers of the towel, even when made of different material.

A treating liquid containing the cleaning ingredients (a fine abrasive powder for cleaning and removing tarnish) and the polishing ingredients is prepared. The polishing materials are essentially non-aqueous liquids and act as the carrier or vehicle for the cleaning material. The cleaning material can be any fine abrasive powder, preferably in the micron range, such as anhydrous aluminum silicate and diatomite. The cleaning, polishing and oxidation retarding materials are dispersed in the liquid. A variety of non-aqueous liquid vehicles, which are useful for the purpose of the present invention, may be used. Among these are liquid hydrocarbons and glycols. The preferred liquid carriers are the liquid hydrocarbons, e.g. normally light liquid hydrocarbon oils, paraffinic hydrocarbons, natural mineral oil, and white mineral oil, kerosene (refined), stoddard solvents and napthas.

An example of a treating liquid which has been found to provide good results in treating a towel contains about 40 percent of a light petroleum distillate; 4 percent of a light mineral oil; 5 percent of silicones and waxes; and 51 percent of a fine abrasive powder, such as Snow Floss," Super Floss or Kaopolite. Kaopolite is an anhydrous aluminum silicate marketed by Harold M. Johnson, Inc. of Elizabeth, New Jersey; Snow Floss and Super Floss are celite diatomite minerals marketed by Johns Manville Corporation. The percentages of materials indicated in the above example are based on the total weight of the treating liquid made in accordance with this invention. The complete mixture is stirred to provide a homogeneous mixture.

The relative proportions of the ingredients contained in the impregnating liquid may be varied considerably without departing from the spirit of this invention. The range of the polishing ingredients or non-aqueous liquid vehicle added can vary from about 25 to about 75 percent of the treating liquid; the rust or oxidation retarding material can vary from A to 12 percent; and the cleaning ingredient can vary from about 25 to 75 percent, all percentages being by weight of the treatment liquid.

Since the products of the present invention generally come in contact with the skin, the ingredients generally employed are those that are non-toxic or non-irritating when the treated towel contacts the skin.

A predetermined quantity of treating liquid, which contains the cleaning and tarnish removing ingredient, the polishing ingredient, and the tarnish or oxidation retarding ingredient is dripped or sprayed onto the outer surface of the first layer 12 of the multilayer towel 10. If the solution is dripped on to the first layer 12, narrow channels 22, 24 of the cleaning and tarnish removing abrasive are formed across the first layer from one side edge to the other, to insure contact with the surface of be cleaned.

The first layer of the towel filters out and retains the abrasive material in a semigelatinous state on the top surface. Thus, the abrasive is carried on the top surface of the first sheet 12 in an essentially non-drying carrying agent which helps the abrasive to adhere to the surface without caking up or flaking off. Also, some of the abrasive material is caught in the interstices of the first layer of the towel.

Through capillary action, the second sheet 14 and, when present, the third sheet 16 absorb the polishing and oxidation and tarnish inhibiting ingredients, which spread uniformly through these layers. After the treating solution has distributed itself evenly throughout the second and third sheets, the entire towel feels dry to the touch.

In practice, the towel can be folded and packed in a transparent plastic envelope immediately after having been treated. The first sheet 12 will automatically filter out and retain the abrasive powder in operative position. Capillary action will occur while the towel is packaged and in transit to a distribution center so that the polishing ingredients are spread evenly through the second or more layers.

The invention here disclosed will clean and polish silver and other metals and deposit an invisible film on to the surface to retard oxidation and tarnishing.

In operation, the towel is removed from its bag and, while being held in a users hand, the first side 12 is rubbed against the metal surface of silver or other metals that are to be cleaned. After the metal surface is clean, the towel is reversed and the bottom, or third, sheet 16 is then rubbed against the cleaned surface to polish the surface and apply an invisible film on to the surface to retard oxidation and tarnishing. The towel can be used again and again until its cleaning and polishing abilities have diminished to a point where they are no longer acceptable and the towel is discarded.

An impregnated sheet or towel made in accordance with the present invention is soft and pliable, so as to cover all of the areas or surfaces to be wiped or polished and not mar or scratch any surface.

Since the treating fluid is applied to a completed strip of composite material, only a single application of liquid is necessary. Further, the sheet material can be assembled in the untreated state, so as to avoid the necessity of careful handling. The composite strip material has different physical characteristics on opposite surfaces. The first layer allows the cleaning ingredients to pass, but retains the polishing ingredients on its upper surface; the second or more layers are absorbent to distribute the polishing ingredients uniformly throughout. These absorbent layers advantageously have some wet strength to resist the rubbing inherent in polishing.

Obviously, many modifications and variations of the present invention are possible in the light of the above teachings. It is, therefore, to be understood that the invention may be practiced otherwise than as specifically described herein.
