was Sept; 15, 1931 UNITED STATES PATENT OFF-ICE rant 1:. nnnniixm, or Los ANGELEs, camronnia minarcan'r Ann cannon nn movnn No Drawing.

Application as April 6, 1929. serial in. 353,264.

It is the object of'this invention to pro- 1o vide'a composition of matter of this character .which may be readily introduced with- .in the motor cylinder, preferably in fluid form, and distributed over the surfaces to be treated and conditioned, and which will be superior in point of inexpensiveness, facility of handling and introduction into cylin safety in storage, handling and use, dom from deterioration, tiveness and efiiciency'in service.

With the above ob ects, together Wlth'Otlh ers that will appear, the invention consists in the novel and useful "provision, association and action and effect of ingredients and substances entering into the composition, and of the composition, all as hereinafterdescribed and finally ointed out in claim.

In practicing the invention 'in a preferred manner, and in the utilization of acceptable and preferred ingredients and substances, in admixture, and preferably in liquid form, I

ders, free- I provide a carbon remover and carbon bond .a-highly efi'ective removal g'of all the carbon occurs. The Eocene, which'is a lubricant, acts to dilute the lubricating oil and to in-' crease the bulk thereof, so that this component part of the compo'und'increases the effectiveness of lubrication of the parts of the motor to which it has access. v

" The cleaning or conditioning factors or elements of the composition, to-wit carbon bond solvents, coact with the lubricating ingredients last mentioned, and in removing the carbon deposits they provide a bright clean surface for reception ofthe lubricant 1 solvent such as trichlorethylene and acetone,

a lubricant, preferably any light mineral oil, and a thinner for the lubricant, such as 35 Eocene. Eocene is a petroleum product of the illuminant group lying between kerosene and signal oil in the petroleum series and has slow burning properties. The carbon which becomes deposited upon the interior cylinder surfaces, pistons and valves and valve seats and other parts reached by the products of combustion in internal combustion motors, is understood to include both crystalline carbon and amorphous carbon, the latter mixed with a heavy petroleum residue of the fuel bonding toget er the, carbon crystals, and thus acting as a binder.'- I'have found "that the acetone and trichlorethylene act as a ready solvent for such residue in the carbon bond. In their combined action I find-that and its effective functioning in the coaction of the pistons, cylinders and valves and valve seats. So that all of the ingredients produce a highly efficient ultimately unitary efiecth. and general eifec- While it might be-possible to obtain .approximately satisfactory results inthe employment of but one of the solvents mentioned and in the employment of the lubricant men- 1 tioned without the thinner therefor, I find that better results ar'e'obtainedin the provision of all of the kinds of ingredients mentioned. g These ingredients are preferably :com-

mingled, as fluids, in substantially the fol-- lowing proportions, to-wit: in a total volume of 55 gallons, 4.0 gallons of Eocene, 12 gallons of light mineral oil, 1% gallons of trichlorethylene and 1% gallons of acetone. Of course, material variations may be made from these relative quantities ofthe ingredients without departing from the inventlon, and similarly, within the invention, variations and substitutions of materials and substances having qualities akin to those of-the specified materials may be made.

The com osition of matter, in its fluid form, may lie injected or introduced within 90 the -cylinder*through the intake valve with the carburetted mixture, and readily distributesitselfover the surfaces of the cylinder, piston, valves'and valve. seats and all surfaces subjected to heat in the operation of the motor. The carbon and carbon bond removed by the solvents from .the surfaces,

plosive mixture, and the lubricant covers the cleaned and brightened surfaces from which the carbon has thus been removed and discharged. Thus, thorough cleaning and conditioning of the surfaces of the thermally affected working parts of the internal combustion motor take place and are affected during the normal operation of the motor and Without taking the same down or discontinuing service. The composition is introduced into the motor in the manner specified at appropriate intervals of time, or whenever indication, by tests or otherwise, denote the necessity for such cleaning and conditioning and lubricating.

Having thus disclosed my invention, 1 claim and desire to secure by Letters Patent:

A composition of matter, including a light mineral oil, a thinner for the mineral oil, trichlorethylene and acetone, in admixture, substantially in the proportions by Volume of 40 parts Eocene, 12 parts of mineral oil, 1 4 parts trichlorethylene and 1 parts acetone.

In testimony whereof I have signed my name to this specification at Los Angeles, Calif., this 30th day of March, 1929.
