WINDOW LIQUID.

Ne Drawing.

This invention relates generally to window panes, and has more particular reference to a novel liquid for application to the window panes for preventing water or snow from clinging thereto.

The invention has for an object the pro-- vision of an improved window liquid which will be elficient in action, and which can be manufactured and sold'at a reasonable cost, and which contains nothing of an injurious or deleterious nature.

lhe liquid applied to a window pane also prevents the formation of frost thereon.

F or further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description, and to the appended claims in which the various novel features of the invention are moreparticularly set forth.

In compounding the invention liquid, use

-is made of paraflinum liquidum (paraffin oil), Oregon balsam lir (kandabalsam), Xylene (xylol), toluene (toluol), melted celluloid, ethyl acetate, acetone, and castor oil. The compound functions without the use of thecastor oil, but a streaky appearance in the final result is present, which appearance is made smooth and streakless by the use of the castor oil. It may be desirable to have the liquid coloured, and any suitable paint may be used, such as fuchsin.

The invention liquid may be compounded, for example, by thoroughly mixing together 3 grams of paraffin oil, 1. gram of castor oil, 3 grams of kandabalsam, 3 grams of toluol, 1 gram of melted celluloid, 1 ounce of ethyl acetate, and 1 ounce of acetone. Colouring may be added so as to obtain any desired shade.

The resulting liquid is suitably bottled and thus sold. The liquid may be applied to either side of a window, or to both sides. Before applying to a Window it is desirable to wash and dry the window thoroughly. Thereafter apply with a soft brush, using an up and down stroke. To obtain the best results, for automobile windows, apply While the car is in a garage and the windows and doors of the garage are closed, so that dust cannot deposit on the glass while applying the liquid. After applying the liquid is left to dry forming like a skin over the window, which can be removed by scraping. The invention liquid is non-flammab so there is no danger of fires.

Application filed October 21, 1926. Serial No. 143,299.

In providing a coating for gla'ss which will prevent the collection of water thereon it isessent'al to employ a substance which will be transparent when dry, which may be easily applied in a smooth thin coating and which will resist the formation of drops of water and the collection of such drops of water on the surface of the glass. It has has been found that melted celluloid together with kandabalsam provides a lac uerl'ake substance having the desired qua ities and well adapted to be used on glass. It has been further found by experiment that a solvent resulting from mixtures of ethyl acetate, acetone, toluol, and Xylene provides a most satisfactory solvent which is highly volatile, and thus renders the composition capable of drying rapidly. These partied lar ingredients produce a transparent coating which flows freely from a brush. The

presence of the oils in the composition causes the same to resist the collection of water on the surface of the dried coating.

Since water vapor, snow, etc., cannot cling to a window treated with the invention liquid, the windows remain transparent regardless of snows, rains, etc.

lVhile I have described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details, or otherwise altering the arrangement of the correlated parts without departing from the spirit or the scope of the appended claims.

Having thus described myinvention, what I claim as new and desire to secure by United States Letters Patent is 1. A window liquid, for preventing moisture, formation of frost, rain, or snow from engagin on windows, comprising paraffin oil, kan dabalsam, 'xylol, toluol, melted celluloid, ethyl acetate, acetone, and colouring means.
