Having thus described my invention, what I claim as new and desire to protect by Letters Patentis:
1., The process of obtaining a composite lubricant comprising distilling acids and aldehydes 'ofi' from castor oil to eliminate about 6.5% of the whole mass, blowing the resulting .product heated to a temperature of from 75 to 150 centigrade with air until the gumminess begins to show a rapid increase with the viscosity greatly increased, and mixing the resulting product with light viscosity mineral lubricating oil in quantities suflicient to obtain'a lubricant of desired viscosity.
2. The process of obtaining a composite lubricant, comprising heating medicinal cas tor oil in a still at atmospheric pressure until a proximately 6.5% of the acids and aldehy es have been driven ofl", forcing air through the heated residue until the gumminess of the mass begins to increase rapidly, and mixing the heavy resulting product with light grades of mineral oil lubricant in the proportion desired.
3. The process ofobtaining a composite lubricant comprising distilling oif from castor oil the acids and aldehydes to about 6.5% of the mass, blowing the residue with air until a point of rapid increase of gumminess is reached and mixing the resulting product with lighter mineral oil lubricants in the manner set forth.
In testimony whereof I hereunto aflix my signature this the 7th day of July, A. D.
DEMPSEY KEMP DODGE.
