PAINT.

- Specification of Letters Patent.

- I Patented Aug. 6, 1907.

Application filed February 7,1907. Serial. No. 356,128.

Be it known that I, GEORGE W. ALLEN, a citizen of the United States, residing at Riverside, in the county new and useful Improvements in Paint, of which the following is-a specification.

My invention relates to paints. Its' object is to provide a water-proof and fire proof paint suitable for coating wood or metal and which possess such elasticity that when applied to sheet metal the latter may be bent or handled regardlessly, without danger of the paint cracking or chipping.-

The invention comprehends' essentially the use of California crude oil of asphaltum base as'a body or vehicle to which is added graphite to give it the qualities to resist the elements,'a drier; a suitable thinner, and appropriate coloring matter.

Crude oil, graphite and a drier enter into all my forto conditions. By crude oil, I mean crud'eoil of asphaltic base, and of from 8 to 20 gravity Baum. Tl e qualities given tothe paint by the use of the crude oil, are elasticity and resistance to the elements, especiallymoisture. The purposeof the graphite is to give added elasticity and also to render the paint still more resistant to the elements, especially heat. The more the less liable to crack. The amount of graphite to be used to a gallon of crude oil varies from a quarter of an ounce to six ounces, according to the amount of elasticity desired, and according to the conditions under which the paint is to be applied. The graphite has a quality of not only rcndcringsubstances waterproof to which the paint is applied, but it resists the heat of the sun or the heat arising from boilers, and so keeps the paint from' running. The more graphite that-is used the better it resists thehcat and'moisture.

. vAs asamplc formula for roofs, bridges, stand-pipes, smoke-stacks, ctcetera, under climatic conditions, such as prevail in Southern California, I would use about the following: crude. oil (8 to 20 gravity Baum), 1 gallon; graphiteto lounce; drier, 1 quart; (or litharge of a pound.)

If the paint is to be made black, I would add, say i of a pound of lampblack. Of course it is understood portions of the several ingredients may vary slightly from the above, according to the conditions under Wui' i the paint is used. Thus I might use from 1% pints to 2 quarts of drier to a. gallon of crude oil, depending entirely upon the climatic conditions and as to whether the job needed to be dried in a hurry. For other colors I might employ prince metallic, venetian l red, ocher, or chrome green. Of the first three colors used there should be from one to three pounds to a gallon of crude oil, according to the depth of color desired; of the chrome green from one to ten ounces would be sufiicient. If the mixture needs thinning I employ kerosene, benzin, or crude carbolic acid; the quantity used depending on the density of the oil and the purpose for which the paint is to be used. On wood the paint is much thinner than on iron and steel. Crude carbolic acid besides being a good thinner, is a splendid preservative when applied to wood, and as a rule would not be used when painting on metal. It makes no difference what kind of a thinner is used, whether kerosene, benzin, or other chemical or substance, so long as it serves the purpose.

Lampblack is used solely for coloring, and the quantity employed'would vary from one to 8 ounces per gallon of crude oil, according to the luster and brilliancy desired.

One of the essential elements of the paint is the drier for without the drier the paint would never dry. Any well known and appropriate liquid drier may beused. without departing from the spirit of my invention. Whcn'using lit-barge I prefer to employ the same in powdered form.

This paint does not break or crack under force or pressure; even by pounding with a hammer when applied to tin or sheet metal; for instance the tin may be bentpr broken without even making a crack in the paint; it also preserves the material-on which it is spread, muchbettcr than ordinary point.

In the preparation of the paint, the oil should be heated suflicicntly to evaporate all the water from it, since the drier the oil is the better it is for the paint. It makes very little difference at what temperature the mixture is made aside from producing in the first place and before mixing the necessary dryness just montioncd. l

Having thus described my invention, what I claim and desire to secure by Letters Patent, is,

if paint comprising the following ingredients in cornhlnulion: crude oil of from 8" to 20 gravity Bnuni, a drier. :1 suitable thinner, and coloring mutter.

2. A point having in combination the following ingro- (Hoots in about the following proportions: crude oil of aspl-mltic vlmsv. one gallon; graphite, approximately one ounce: drier, approximately one quart; and :1 suitable coloring mutter.

in testimony whereof I have hereunto set. my hand in prosi-nco of two subscribing witnesses.
