MIL'I ON C. WHITAKER, OF YORK. N. Y., ASSIGNOR TO U. 'S. INDUSTRIAL ALCOHOL CO., A CORPORATION OF WEST VIRGINIA.

INTERNAIJECOMBUS'IION-ENGINE FUEL.

T 0 all whomit may concern.- A Be it known that I, MILTON C. YHITAKER, a citizen of the Fnited States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Internal- Combustion-Engine Fuel, of which the following is a specification. f

My invention relates particularly to fuels designed to be'used in aeroplane motors, but is applicable for use in internal combustion motors of all kinds used in flying or for other purposes. 2

The object of my invention is to provide a fuel which is especially adapted for use n aeroplanes, although it is also applicable for.

use in internal combustion engines in general.

n It is necessary that fuels which are to be used in aeroplane motors shall have great dependability, inasmuch as any uncertainty in the operation of the aeroplane by reason of variability in the character of the fuel or failure of the fuel to perform 'its intended work, may bring about disastrous consequences.

For this reason, it is desirable to avoid -...,,using in such fuels large percentages of petroleum products, inasmuch as commercial petroleum products do not ordinarily have a constant composltlon', and are-usually comprised of varyingquantities of a number of different constituents. It is, therefore, the object of my invention to provide a motor fuel avoiding these dis advantages and taking into account the circumstances above referred to.

Still a further object of my invention is to provide fuels of'the above character by the use of ketones but especially higher ketones, that is to say, ketones other than acetone.

Further objects of my invention will appear from the detailed description thereof contained hereinafter.

While my invention is capable of being carried out in different ways, r the'purpose ofrillustration I shall describe only certain ways of carrying out the same herein.

For example, a fuel made in accordance with my invention may be comprised of 35-parts by volume of acetone,

25 parts by volume of. alcohol,

5 parts by Volume of ethyl acetate,

Specificationcf Letters Patent. Patented June 2Q, 1922 Application filed November 12, 1919. Serial No. 337,395.

17% parts by volume of. kerosene,

17% parts by volume of gasoline.

Another example is:

35 parts by volume of methyl-ethylketone, V

25 part'sby volumeof alcohol,

5 parts by volume of ethyl acetate, 17% parts by volume of kerosene, &

17 1}; parts by'volume of gasoline.

Another example is:

35 parts by volume of diethylketone,

25 parts by volume of alcohol,

5 parts by volume of ethyl acetate, 17% parts by volume of kerosene,

17:1- parts by volume of gasoline.

The above compositions may be varied to a considerable extent. For example, the kerosene and gasoline may be substituted by the same total quantity of a single petroleum distillate, such for example as gasoline or kerosene. Instead of ethyl acetate, I may use any oneof a number of esters, as for example methyl butyrate, ethyl butyrate,

2. A fuel comprising approximately equal proportions of a ketone, an alcohol, and a light petroleum distillate, with a smaller I proportion of a volatile ester.

3. A fuel comprising a light hydrocarbon, alcohol, diethyl ketone and ethyl acetate.

4. A fuel comprising about 35% ketone,

about 25% alcohol, about 35% pe troleum distillate, and about 5% of an ester."

5. I i fuel comprising about 35% diethyl ketone, about 25% alcohol, about 35% petroleum distillate, and about 5% ethyl acetate.

In testimony that I claim the foregoing, I have hereunto. setmy hand this 6th day of November, 1919. i
