13 Claims. (01. 15-209) The present invention relates to an article of manufacture suitable for. cleaning and polishing and, more specifically, .to a composite sheet of paper containing an oily polishing medium-in 5 only a portion thereof, and with the remainder of the sheet free from such oily material, or containing other materials of the same character, and means for preventing the capillary How of the impregnating material over the entire sheet. My invention will be fully understood from the following description and the drawing which 11- lustrates a form of my improved polishing paper.

In the drawing Fig. 1 illustrates a sheet of absorbent paper indicating the area saturated with 15 means for preventing capillary flow; and

Fig. 2 indicates a similar application of my invention in which the sheets are shown in a convenient package with means for preventing capillary flow from the several separate areas into one another, and likewise into the package wrapper.

Referring to the drawing, in Fig. 1 the reference character 1 designates a sheet of paper, preferably of soft, uncalendered, unsized or glazed type capable of absorbing a considerable quantity of a suitable liquid. For this purpose I may use a mate-- rial similar to that from which the ordinary blotting papers are made, but preferably I prefer a thinner, stronger and more fibrous stock such as is used for the manufacture of paper towels- The sheet is divided into two areas marked gen-- erally 2 and 3 by a narrow band, or zone 4. The areas may be equal or unequal, and may be of any suitable shape, although it is most convenient that the sheet be divided by a straight line passing across its face. The narrow band, or zone 4 is suitably treated so as to greatly reduce its capillarity and to prevent capillary flow of a liquid material from one portion of the sheet across the band into the other portion. This may be done in a variety of different ways; for example, the narrow band'is treated with a suitable sizing material. As sizes glue solutions are perhaps. the most. satisfactory, but gelatinous, inorganic materials such as aluminum hydroxide,-

chromic or ferric hydroxides can also be used; If desired, a glue solution-may be used and it may be rendered substantially insoluble by treatment hyde. Rosin or other resins either natural or synthetic such as paracoumarones, and.condensa-'- the oily material, an area free from the same, and.

witha small amount of formaldehyde or paralde-' like which do not perceptibly wet paper. Thicksoap solutions may be used also for this purpose. The capillarity of the paper in the narrow, separating zone may be reduced by impregnation with other suitable materials which are diflicultly solue0 ble in the fluids to be used and which are themselves incapable of capillary flow. Paraflln wax may serve this purpose, and preferably the higher melting point grades are used which are also less soluble in oily compounds. Paraflin waxes witha 5 melting point of say 110 or preferably 120' F., or higher, are suitable for this purpose. Japan wax is likewise suitable, or carnauba, or candelilla, or beeswax, or suitable mixtures of these materials with each other, or other ingredients 7 which may be added to produce a readily flexible material which will be substantially solid at ordinary temperatures and which will saturate paper in a relatively narrow portion and render it unable to conduct liquid materials from one area 7 into the other. Perforations indicated at 5 may be provided through the zone 4 in order to assist in the tearingof the sheet. I

' The areas 2 and 3, or either of them, are then impregnated with a suitable fluid substance, preferably of an oily character if the purpose is 'for cleaning and polishing. Mineral oils such as spindle oils or the lighter grades of lubricating oilmay be used, or animal oils such as neats-foot oil or degras, or vegetable oils such as linseed, 35 castor and the like, or suifonated oils-of the type of Turkey red oil may serve my purpose.

If desired, both of the areas 2 and 3 may be impregnated with the same oil say in different ,degrees of saturation, for example, one of the areas may contain a relatively small amount of the oily material substantially less than is required to fully saturate the paper, and best adapted-to gather dust from the furniture or other article to be pollshed The other portion .95 may be fully saturated with the same oil which is desirable for-the most eflicient polishing. Similarly, the two -oils may be entirely different in then-composition. For example, the dust-gathering oil may be a light spindle oil containing tur-- m0 pentine, while the polishing oil may be linseed oil withior without lubricating oil, or lubricating oil alone. (items may be used instead of .oils for one or more of these purposes and, if desired, other substances may be added to, the oil or grease such as flne abrasives of the type of rotten stone, 1 talc or bentonite. Similarly, wax may be used. in veryv small amounts to give a high polish on a fine wood or-lacquer surface. For this purpose no a relatively small amount of the softer greases or parafiin waxare to be preferred.

In Fig. .2 a package of sheetsv similar to those illustrated in Fig. 1 is shown with a part of the wrapper 6 tom away to show the sheets 1 which in this case are divided into areas 2, 3 and 3a by the narrow bands or zones 4, as indicated before.

oily material from one or more of these impregnated areas into the wrapper 6. Glazed paper may be wrapped about the bundle of sheets, or a single glazed sheet may be placed on the top and bottom of the pile as indicated at '7.

When adapted for polishing furniture, or other fine wooden or lacquered surfaces, one area of the sheet will suitably contain a mixture of turpentine and a lubricating oil in relatively small amount, that is, the paper will not be fully saturated. This is found to be excellent in removing dust and dirt film and to prepare the surface for receiving a high polish. A relatively soft abrasive as indicated above could also be included. The other area would be substantially saturated with a polishing oil such as linseed oil, or mineral oil or a mixture of these two. A suitable composition for this purpose is as follows:

Cleaning area Polishing area I Percent Percent Mineral oil (spindle) 90 Mineral oil (spindle) -.90 Turpentine -1 .l0 Linseed-oil 10 I with cosmetics.

The cleaning paper contains about .012 cc. of the oil per sq. inch of paper while the polishing paper contains about .125 cc. The separating zone in this case is made by applying a solution of rosin in isopropyl alcohol to the paper. Myinvention may be applied for other purposes, for example, it may be used in connection In such caseone portion of the sheet may contain cold cream, the other being unimpregnated. Three areas are suitably applied in this case, the third containing a free powder capable of easy removal.

My invention is nbt to be limited to any theory of the manner in which oily materials are kept in place and prevented from mixing, nor to any particular substance for impregnating the sheets, nor likewise to any specific material'or method for reducing the capillarity of the paper in the narrow zones separating the various areasof the sheet. My invention is to be limited only by the following claims in which I wish to claim all novelty inherent in the'prior art.

I claim:

1. A new article of manufacture comprising a sheet of absorbent paper divided into a plurality of areas by narrow zones wherein the paper is treated to greatly reduce its capillarity, and one paper with a compound of said areas being impregnated with a cleaning compound.
