- OF WHITIN G, INDIILAIN'A, A CORPORATION OF INDIANA LUBRICANT No Drawing.
- r This invention relates to lubricants and particularly to lubricants for aeroplane motors. s
According to the invention the lubricant consists of a base of lubricating oil, together with a relatively small amount of a relativey high volatile and substantially uninflammable diluent. 1
The lubricating oil may be of viscosity and lubricating properties suitable for any particular type of engine unden operating conditions. As thevolatile and uninflammable or relatively uninflammable diluent, itis preferred to employ carbon tetrachloride, but it 1 is within the scope of the. invention to use chloroform or other suitable halogen substituted hydrocarbons, or a mixture of these with relativelysmall quantities of volatile hydrocarbons.
The lubricant may suitably consist of about 90% to 95% of hydrocarbon lubricating oil and 10% to 5% of volatile, uninflammable diluent. For use as an aeroplane oil in cold weather, the viscosity of the mixture may suitably be between 60 and 80 seconds Saybolt at 210 F. and less than 100,000 seconds Saybolt at F.
The diluent should be of such a volatility that it is substantially completely eliminated after full-load operation of the engine for about one hour or for a considerably shorter time especially where the diluent is uninflammable to a high degree. In general, a product boiling below 250 F. will have the desired degree-of volatility.
By way of example, the following composition is given:
Lubricating oil 7 seconds Saybolt viscosity at 100 F., pour at 10 F 93% Carbon tetrachloride 7% The mixture has a viscosity of 85,000 seconds Saybolt at -2() F. and 400 seconds Saybolt at 100 F. The diluent is substantially completely eliminated after half an hour full-load operation of the engine so that the oil increases in viscosity to 730 seconds Saybolt at 100 F. and 65 seconds Saybolt at 210 R, which insures satisfactory lubrica- Applicat ion filed October 19, 1927.

tion for the engine undefi operating conditions.
- The improved lubricant is particularly suitable for use in starting aeroplanes in very cold weather, since it insures oil circulation and lubrication when starting the engine and since the diluent is eliminated in a relatively short time, eflicient lubrication is insured during prblonged operation. Moreover, danger of explosion in the crank-case is avoided by the selection of a non-inflammable diluent. The use of a hydrocarbon sufliciently volatile to behave in a similar manner results in a very low flash test for the oil, making it rather unsafe to handle and store.
The oil may be prepared by mixing the ingredients before supplying the oil to the engine, or, if desired, the appropriate amount of diluent may be supplied to the oil in the crank-case. The latter method is particularly suitable where the aeroplane has been operated for some time so that the diluent has been eliminatedand then the engine stopped and allowed to become cold.
Although the invention has been described in connection with the details of a specific example thereof, it must be understood that it is not'intended to be limited thereto, except insofar as included in the accompanying claims.
I claim:
1. A lubricant for internal combustion engines comprising a fluid lubricating oil and a relatively volatile and substantially uninflammable diluent.
2. A lubricant for internal combustion engines comprising a lubricating oil of characteristics suitable for the effective lubrication of the engine under operating conditions and a relatively small amountof avolatile substantially uninflammable diluent.
3. A lubricant for internal combustion engines comprising hydrocarbon lubricating oil and a halogen substituted hydrocarbon boiling mainly below 250 F.
4. A diluted lubricant comprising a mineral lubricating oil and a chloro derivative of a hydrocarbon boiling mainly below 250.
5. A diluted lubricant comprising a mineral lubricating oil and carbon tetrachloride.
'6. A lubricant for internal combustion engines comprising to of lubricating oil, and 10% to 5% of a halogen substituted hydrocarbon.
7 A lubricant for internal combustion engines comprising 90% to 95% of lubricating oil, and 10% to 5% of carbon tetrachloride.
8. A lubricant for internal combustion engines comprising 90% to 95% of lubricating oil, and 10% to 5% of carbon tetrachloride, and having a viscosity between 60 and 80 seconds Saybolt at 210 F. and less than 100,000 seconds Saybolt at 20 F.
9. A lubricant for internal combustion engines comprising 93% of a lubricating oil having a viscosity of about 7 30 seconds sa bolt at F. and a pour of about 10 F., and about 7% of carbon tetrachloride.
10. A lubricant forinternal combustion engines constituted mainly by hydrocarbon mineral lubricating oil of viscosity and lubrieating properties suitable for the engine underoperating conditions and not more than 10% of a readily volatile ,and substantially uninflljammable diluent boiling mainly below 250 11. A lubricant for internal combustion engines comprising a lubricating oil of characteristics suitable for the effective lubrication of the engine under operating conditions and a relatively small amount of a substantially non-inflammable diluent boiling mainly below 250 F.
In witness whereof, I have hereunto set my hand this 13th day of October, 1927.
