gheny, and State of Pennsylvania, have in' vented certain new and useful Improvements in Oil Compositions; and I do hereby dee clare the following to be a fullfclear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the samei This invention relates to oil compositions; and it relates more particularly to an oil composition comprising a mineral oil base in which is dissolved camphor, said com position being of special utility for lubrieating. leaf springs on motor vehicles, for loosening nuts, machine screws, or the like, that have become rusted or otherwise fixed in-place, and for other-analogous purposes.

' In general, the oil constituting the base of my novel oil composition should be mineral oil; and most desirably there should be no animal or vegetable oil in the composition. .Dissolved in the mineral oil base is a quantity of camphor, ordinary commercial gum camphor being suitable and being employedin proportion which may vary but which ordinarily small. The complete oil 0 composition should be penetrating 1n character so thatit may readily enter extremely small cracks and crevices, but it should nevertheless embody good lubricating properties. The camphor contributes toward the penetrative characteristic; also it acts as a rust-cutting agent .and rust deterrent, the

, term rust being here used broadly to designate any form ofcorrosion or the like that causes contacting parts to become locked or ffrozen together. The mineral oil base may vary considerably in its specific character so long as it provides, in combination with the admixed camphor, a highly penetrating oil composition, carrying lubricating 5 values and possessing rust-cutting and protective properties as hereinabove set' forth. By wayof a concrete example embodying "the principles of the invention, reference may be made to one specific form of my 59 novel composition which has proved especially efiective in use and which constitutes the best'mode now known to me of practicing the invention. In this particular instance, the mineral oil base consists of a mixture of good quality lubricating oil, such as Application filed Kay 6,

a medium motor oil, and a high grade Pennsylvaniai crude petroleum; and with this base is incorporated the desired amount of commercial gum'camphor. The ingredients mayadvantageously be compounded in the approximate proportions of 4 parts of said lubricating oil, Il parts of the crude petroleum, and y -part camphor, ali parts being by weight. Although these proportions are especially desirable and are recommended as best, they may be varied considerably while stillcrealizing the benefits of the invention to a substantial extent. A convenient way of incorporating the camphor with the oil is to dissolve it in a part ofthe crude oil with the aid of heat, and then to mix the solution with the rest of the oil. Thisis merely typical, however, of procedures that may be followed. The use of heat is not es-' sential although it expedites the operation of compounding the mixture. In general, the proportion. of camphor need not exceed 2 ounces per pint of the finished composition, and a substantially'smaller proportion is or:

' In the specific example above given, the lubricating oil employed tested as follows: Baum gravity 28.7; viscosity at 100 F., 300; flash, 435 F.; fire, 485 F.; pour test,.20 F.; demulsibility, 172; conradson carbon, .25%;- acid number, .09 equal to .05% loleic. i I

The crude petroleum tested as follows Baum gravity, 47.0.; distillation, initial boiling point, 50 C.; 10% over at 113 C.; 20% over at143 G; 30% over at 170 (3.; 40% overfat 210 (3.; 43% over at 220 C. (yield of gasoline); 50% over at247 0.; 60% overat 288 C.; 63% over at 300 C. (yield of kerosene). I

The use of a crude petroleum in the mixtureis-advantageous because it carries not only a certain proportion of lubricating oil fractions but also lighterfractions, such as the gasoline and kerosene fractions, that contribute toward thepenetrating-character of the final composition. l i

The complete finished composition ob- I tained in the above specific example thinly fluid and highly penetrating, shows a typical mineral oil bloom, and'nnlells-stronglyfof camphor.

It is to be understood that theforegoing specific examples of oils and theproportions in which they are used arenot intended as 9 restrictive but only as illustrating how a typv phor in an oil consistin "ical and especially desirable oil composition within the scope of my invention may be prepared. Repeated tests of novel oi com' positions embodying my invention have established their effectiveness andivalue for the purposes in View.

I What I claim is:

- 1., As a new article of manufacture, an oil composition comprising a solution of camof a mixture of a ubricating oil with cru e petroleum. 2. As a new article of manufacture, an oil composition comprising a solution ofabout part of camphor in about 15 parts of a -mixture of crudeipetroleum and refined lubricating oil. 3. As a new article of manufacture, an oil signature. I

usages composition comprising a solution of about M; part of camphor in about 15 parts of a mixture comprisin about 11 parts of j Pennsylvania or ot er parafiine base crude petroleum and about 4 parts of a medium motor lubricating oil. 4. As a new article of manufacture, an oil composition comprising a solution of camphor in mineraloil comprising both a mixture of refined lubricating oil and crude petroleum, the proportion of camphor not exceeding 2 ounces per pint of said composition. In testimony whereof I hereunto JOSEPH ALEXANDER X YOUNG.
