LUBRICA'IING COMPOUND.

No Drawing.

I T 0 all whom it may concern Be it known that I. DANIEL. M. SoRENsoN, a subject of the King of Great Britaimresiding at Toronto. in the county of York, in the Province of Ontario. Canada. have invented a certain new and useful Lubricating Compound, of which the following is a specification.

In the application of oil for lubricating purposes in machinery and internal combustion engines and-particularly in automobiles, it is invariably found that after more or less extended use. and depending on the presence of foreign matters therein and to a large extent also upon the viscosity of the oil, such lubricants gradually deteriorate,

the oil globules break down and become gradually ineflicient for the purposes of lubrication, and by reason thereof a frequent renewal of the oil is necessary.

Ordinary lubricants also tend to create a glaze upon surfaces which are intentionallybrought together for frictional purposes as, for example, the bringing of a brake band into contact .with a brake drumand render such contact ineffective for the purposes of the contact. 1

My compound is intended to prevent such deterioration of the oil lubricants as above mentioned and to prevent the formation of the glaze above referred to.

In preparing my compound, I employ as a base or foundation an ordinary neutral lubricating oil (such as defined in Vol. 2 of The American Petroleum Industry, by Bacon and Hamor, published by McGraw- Hill Book Company, Inc., at New York in 1916) having a body varying in viscosity from 200. to 300, Saybolt. at 100 F. To

such base I add not more than 10% in quantity of a pure soap produced by saponifying fish, vegetable, or animal, oil

lubricating oils.

Specification of Letters Patent. Patented A 25, 1922,

Application filed July 11,

1921. Serial No. 483,997.-

the manner above set forth, does not deteriorate or break down under the influence of heat of .ordinary intensity generated by moving surfaces in contact, as do ordinary It creates and maintains a lubricating film between the frictional surfaces and. in the case of automobile'engines. this results in increase-dmileage per gallon of fuel gasoline. The compound not being injuriously affected and carbonized by heatQthe parts to which it is applied will not become carbonized, as is the case where ordinary lubricants are empl'oyed. Furthermore, when used upon frictional surfaces which are not continuously in Contact. but which are brought together at irregulanintervals, my compounddoes not form-a hard glazed deposit thereon. as is the case with ordiriary lubricating oils. but creates a soft film or surfacing which acts as a cushion between the two contiguous surfaces and prevents them from slipping.

The process of treating the brake bands to prevent the formation of a glazed deposit forms the subject matter of my copending I claim:

1. A lubricating compound particularly useful for preventing the formation of hard glazed surfaces on friction bands consisting of a base of neutral oil having an ammonia soap mingled therewith.

2. A lubricating compound particularly useful for preventing the formation of hard, glazed surfaces on friction bands consisting of a base of mineral oil having a viscosity of from 200 to 300 andhaving an ammonia soap mingled therewith.

3. A lubricating compound particularly useful for preventing the formation of hard glazed surfaces on friction bands consistmg of a base of mineral oil'having a viscosltv of from 200 to 300 and having mingled therewith not more than ten per cent of an ammonia soap.
