Description
Patented Jan. 28, 1941 PATENT OFFICE LUBRICANT MANUFACTURE Elliott n. McConnell, Shaker heights, 0516, as
aign'or to'lhe Standard Oil Company, Cleveland, hio,a corporation oi Ohio l No Drawing.
In the operation of internalcombustion engines, the lubricating oil is exposed to extremely drastic conditions, and changes occur in the oil and degradation products tend'to be formed rather profusely. I A particular difliculty lies in the fact that the substances formed are of adhesive character and prone to stick the piston rings, preventing proper sealing, and interfering with normal operation. I havefound that cerm tain compounds afford a surprisingly effective lubricantfor heavy duty operations The action' is not explainable merely as of anti-oxidant character, as sometimesascribed to lubricating oils; as it is efiective also in absence of oxygen, 5' and considering the difference in what degradation products are formed; in comparison with those in a plain mineral oil of the same viscosity, it may be concluded that..the, lighter bodied, lighter. colored resinous material formed is a relatiyelydo'we'r product of polymerization, and an important practical efiectis that its nature is unctuous and oilyinstead of adhesive and sticky as with'mineral oil per Se.
To the accomplishment of the foregoingand on related ends, the invention, then, comprises the' features herelnafter'iully described, and particularly pointed out in the claims; the following description setting forth in detail certainillustrative embodiments of the invention, these,'be-
3o ing indicative however, of but a few of the various ways in which the principleof the invention may be employed.
A minerallubricating oil stock of dsiredvis- .cosity is employed. as the base ofthe. present 3 lubricant. and with it is incorporated acyclohexyl compound which is of amine type. For instanoeflmonocyclohexyl amine, dicyclohexyl amine, tricyclohexyl amine. The amount of the cyclohexyl compound need not be large. It need f 40 not exceed 5 per cent in general, and amounts' as low as 0.01 per cent'are suflicient in many instances. The lubricating all stock may be for example an oil-of to sec. Saybolt Viscosity at 210 F., as derived from any suitable petro- Application October 22, 1938. Serial No. 236,553
(claims. ((1252-50),-
leum, as,Pennsylvania,Mid-Continent, etc. The miscibility of these cyclohexyl compounds is such that they readily incorporate into the oil at generally ordinary temperature.- -Any'special refining treatment of theoil which may have been 5 desired, should have been carried, out prior to this compounding.
As an example: A Mid-pontinent lubricating stock of S. A. E. 30, in amount 99.5 per cent, and dlcyclohexyl amine in amount 0.5 percent are 10 thoroughlyincorporated together. This composition applied asacrankcase lubricant in an internal combustion engine shows remarkable ability to stand up under long continued runs continuously, without. interruption from ring 15 sticking. and the resinous material which occurs is peculiar in being greasy instead of sticky, and it is not easily decomposed by temperatures around 400-500 F., but retains its smooth unctu- -ous character. 2o
Similarly, monocyclohexylamine and tricyclohexyl amine may be substituted train the above,
as may be desired in anyinstance. 7
Other modes of applying the principle or the 'invention'may be employed, change being made M as regards the details'described, provided the features stated in any of the following claims,
1 or the equivalent of such, be employed.
I therefore particularly point out and distinctly claim-asmy invention: I 3.. r 1. A lubricant, comprising a mineral oil of lubricating viscosity and a small amount of a cyclohexyl amine.
2. A lubricant, comprising a mineral oil 01 lubricating viscosity and a small amount of dicy- 35 clohexyl amine.
, 3. Av lubricant,:comprising a mineral oil of lubricating viscosity and a small amount of tricyclohexyl amine. a
4. A lubricant, comprising a mineral oil 01 lu- 4o bricating viscosity and a small amount of monocyclohexyl amine.
