WILLIAM H. DAMON, OF CHICAGO, ILLINOIS.

POLISH AND PROCESS OF MAKING THE SAME.

No Drawing.

To all whom it may concern Be it known that I, WILLIAM H. DAMON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Polishes and Processes of Making the Same, of which the following is a specification.

My invention relates to a polish for automobiles, furniture and the like, and a process of making the same.

Polishes for automobiles, furniture and the like are on the market that are in the form of an emulsion, containing water, a light hydrocarbon volatile at ordinary temperatures, a mild abrasive'such as diatomaceous earth, and soap. The soap is the agent whereby the water and hydrocarbon may be brought into a state of emulsion, in which a mild powdered abrasive is held more or less permanently in suspension. In place of soap other agents such as gum arabic are sometimes used.

I have made the discovery that by a certain treatment, hereinafter described, water and a hydrocarbonyolatile at ordinary temperatures, or any oil, whether vegetable. animal, or mineral, may be brought into a finely di vided state of suspension which is more or less permanent, and in which a finely powdered abrasive of low specific gravity may be ,held more or less permanently in suspension,

thereby doing away with the objectionable use of soap or gum arabic and the like.

-My invention consists of the steps of the process and the resulting product hereinafter described and claimed.

I take one pound of finely powdered fullers earth and mix the same with water. sufficient in amount to form with the fullers earth a liquid of creamlike consistency. About one gallon of water is required. I then add one gallon of a neutral hydrocarbon oil, such as paraffin oil and the like, and thoroughly agitate and mix the same With the cream-like liquid of fullers earth and water. The water, oil, and fullers earth may be mixed with water in any proportion desired, and forms therewith a homogeneous mixture in which the water insoluble ingredients are more or less permanently in suspension. The amount of fullers earth may be increased to two pounds if desired.

The omission of soap in forming the emulsion is a decided advantage for the reason Specification of Letters Patent.

that the alkali present in the soap acts injuriously upon the finish of the surfaces to be polished. lVhere gum arabic and similar substances are used to form the emulsion the presence of gum arabic and the like 15 obiee tionable for the reason that it leaves a smear film on the surfaces to be polished, which.

unless thoroughly wiped off, will prevent a brilliant luster of the surface.

If desired, other ingredients, such as resins, may be added to the polish, and oils, either of vegetable or animal origin, may be used in place of the hydrocarbon oil. In the case of oils of greater specific gravity the quantity of oil may be decreased. In place of the fullers earth any other mild abrasive, such as calcium carbonate or diatomaceous earth, may be used.

My invention is not limited to polishes and the like but may be used in treating oils for medicinal purposes, for instance, castor oil may be more or less permanently suspended in a homogeneous mixture in a menstruum in which it is normally insoluble by my method by means of an inert powder and thus render it less objectionable to the taste.

Various changes may be made in the steps of the process and in the proportions of the ingredients without departino from the spirit of the invention as claimed.

\Vhat is claimed is:

l. A process of treating oil to form a homogeneous mixture with water in which the oil is more or less permanently in suspension, comprising mixing a finely powdered, inert and water insoluble abrasive with water to form a cream-like consistency, and mixing an oily material therewith to form an emulsion.

2. A process of treating oil to form a homogeneous mixture with water in which the oil is more or less permanently in suspension, comprising mixing fullers earth with water to form a cream-like consistency, and mixing a liquid and oily hydrocarbon therewith to form an emulsion.

3. A polish for automobiles and the like consisting of a cream-like liquid containing water and a finely powdered mild abrasive insoluble in water and in oil, the abrasive and oil of the paratfin" series being in a state of suspension more or less permanent.

In testimony whereof I have signed my name to this specification.
