,MANUFACTURE OF LUBEICATING-OILS.
l lo Drawing.
can be made from a natural lubricating oilu lln the practice of my invention I take a grade of crude petroleum oil which is in itself a lubricating oil, being substantially free from gasolene and other highly volatile constituents. This natural lubricating oil is of rich green color, has a specific gravity of about thirty-one and three-tenths B; its flash is 130, its viscosity is 100 at 100 Sayboldt, and its cold test is zero or better. The treatment of natural oils of this class has heretofore been a diflicult one. I take this oil and filter it through fullers earth or bone dust, thereby giving it a lighter color, the filtering being preferably such as will give the oil a color somewhat lighter than that which is desired in the finished oil. The filtered oil is then placed in a still and is heated from 250 to 350F. At this time steam is turned into the still, being preferably discharged into the body of the oil. The lighter constituents are carried over by the still into a suitable condenser. The distillation is carried on until the residue remaining in the still has the desired viscosity. The fire applied to the still is kept checked down, so that the temperature in the still will not,-at any time, much, if any, exceed 400 F. As the distillation proceeds the volume of steam fed in is increased. Steam employed preferably has a pressure of from 50 to 100 pounds and should be as dry as possible, superheated steam being preferred.
The residue left in the still may be used without further treatment, or it may be run through a cold settling system in order to settle out the amorphous wax and improve its cold test. This settling may, however,

be done before initial filtering or after such filtering and prior to the distillation.
The effect of my improved treatment is to materially increase the flash and viscosity of the oil with only very slight reduction in its gravity. My, process enables the manufacture of lubricating oil of this character by a straight run, which may be continued until the desired viscosity is obtained.
I claim:
1. The herein described method of treating a natural lubricating oil to produce an improved lubricating oil of increased viscosity with comparatively slight reduction in gravity, which consists in taking a crude petroleum oil of rich green color, of a gravity of approximately 31.3 B. of 130 flash, of a viscosity of approximately 100 at 100 Sayboldt, and whose cold test is zero or better, filtering the same to give it a color lighter than the color of the finished oil,
heating the same in a still to a temperature not exceeding l00, and injecting steam into the oil while so heated.
2. The herein described method of treating a natural lubricating oil to produce an improved lubricating oil of increased viscosity with comparatively slight reduction in gravity, which consists in taking a crude oil of rich green color, of a gravity of approximately 31.3 H, of 130 flash, of a viscosity of approximately 100 at 100 Sayboldt, and whose cold test is zero or better, filtering the same to give it a color lighter than the color of the finished pil, placing the same in a still and bringing it to a temperature of from 250 to 350 degrees F, then introducing steam into the oil and continuing the heating while increasing the volumeof steam, and maintaining a. temperature in the still not exceeding 400 F.
3. The herein described method of treating a natural lubricating oil to produce an improved lubricating oil of increased viscosityvvith comparatively slight reduction in gravity, which consists in taking a crude petroleum oil of a rich green color having a specific gravity of approximately 31.3 Baum, of 130 flash, of a viscosity of approximately 100 at 100 Sayboldt, Whose cold test is zero or better, filtering the same through fullers earth to give it a color lighter than the 0010i of the finished oil,
lacing the filtered oil in a still and applylng external heat to bring it to a temperature of from-250 to 350 5 duci'ng steam into the F., then introoil and continuing the heating While increasing the volume of steam, and maintaini ng the temperature in cooling the il, and removing the amorphous the still not exceeding 400 F., thereafter HENRY F, GRANT.
