This invention relates to the production of an'improved lubricant, and more particular ly to a lubricatingoil especially adapted for use in internal combustion engines and similar motors, and has for one of its objects to providean improved lubricant which will be more elicient in use than those which have been heretofore proposed.

A further object of the invention is to produce a lubricating oil. possessing an inherent complete laminar orientation .of the lubricating structure, resultingin such a high concentration of true lubricating value as to make possible the use of a single viscosity or weight of the product for all internal combustion engine lubricating requirements; or in other words, one grade of oil for all motors.

A further object ofthe invention is the strippin or elimination of the more volatile, non-wor ing, superfluous, fractions resulting in greater resistance toheat and pressure, as an additional aid toward the practicability of the use'of one supergrade for all motors.

, 'A still further object of the invention is -to provide an improved process for the manufacture of the above described lubricant.

With the above and other objects in view,

lubricant, and in the novel stepsfand combinations of steps constituting the process, all as will appear more-fully below, and be particularly pointed out in the claim. In order that the precise nature of the invention may be better understood, it may be said that it is well known at present that the various makes of internaLcombustion engines possess different characteristics which indicate the use of many different grades of lubricating oils in order to attain'the highest eiciency; and that of the oils now in common use, any one gradewhich may produce the proper lubrication and greatest eiiciency in any particular type or make of motor, may be wholly unsuited for a different make. It is well vrecognized in the industry that it is highly desirable to provide a'lubricating medium suitable to all motors indiscriminately,

up 'in a chamber by means of suitably placed baiie plates in the direct line of the injection spray; this contrivance resulting'in a com- I plete and intimate intermixture both physical and structural. l

Thereafter, this mixture is subject to a temperature of 425 F. for thirty minutes, through the use of su'perheated steam Coils, and about 15% of the mixture in the aforementioned chamber, distilled oi with the additional aid of a partial vacuum. (10# to square inch.- Then to this residuum lremaining in t e chamber, is introduced. .3 of 1% of magnesium stearate, richl in colloids, which is thoroughly intermixed by agitation with air.

The resultant roduct is thenfinished lteed through in usorial earth', to the desired co or.

The above treatment isfound to produce a lubricant in which the colloidal hydrocarbons are so concentrated as to permit of the .use of,v

a single grade of the lubricant in any motor.

In the accompanying drawing forming a part of thisspecication, the .figure is a more or less diagrammatic sectional view of one form of apparatus which may be employed in carrying out the present process. n the said drawing,'1 indicates 'a closed chamber of suitable construction, provided with a series of staggered batlles 2, which may support steam pipes 3. These said pipes, however, may be arranged and supported in any other appropriate manner. Nozzles 4 and. 4 are provided through which 'the lubricat-- e introduced into the' ,chamber 1 under pressure in converging ing components may streams or sprays, and the chamber is also provided with a draw-off pipe 5, controlledY by a valve 6, and an outlet conduit4 7, controlled by a valve 8, which conduit `7 may be connected to a suitable vacuum pum (not shown) for reducing the pressures wit in the chamber at certain stages, all as previously set forth. The stearate and the agitatin air may be introduced through the pipes 10 aving the control valves 11.

It is obvious that those skilled in the art may vary the precise temperatures, times, and pressures employed within certain limits, as well as other minor details of the process, without departing from the spirit of the invention, and, therefore, it is not wished to be limited to the above disclosure except as may be required by the claim.

What is claimed is: i

The process of producing a lubricant for internal combustion motors and the like, whichl consists in injecting substantially equal quantities of two grades of comercial lubricating oil into a closed chamber under heavy pressure, whereby a substantially complete physical and structural intermixture of the two results; subjecting the mixture to the action of a partial vacuum of approximately 10 lbs. heating the mixture to approximately 425 F. to drive off a portion of the li hter fractions; :adding approximately .3 og 1% of ma esium stearate to the residuum while agitating the mixture; and filtering the resulting product.

In testimony whereof I aiiix my signature.
