OSCAR LOEW, on NEW YORK, n. Y., AssreNoR TO JOHN M. PENDLETON,
or SAME PLACE.
Letters Patent No. 101,284, dated March 29,1870.
IMPROVED METHOD OI BLEACHING- AND REFINING OILS.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern.-
Be it known that I, OSCAR LOEW, of the city of New York, in the State of New York, have devised and invented a new 'Process or Method of Bleaching and Refining Animal, Vegetable, and Mineral Oils,
which I designate as the cold process, and of which and used for fertilizing purposes.
If the oil to be bleached contains a large amount of gummy matter, it is next heated, with one-half to two per cent. of sulphuric acid, 66 Baum, and after a thorough commingling, it is left to repose. When fully settled, the clearer oil is drawn ofi from the dark sediment.
After the oil has passed through either one or both of the processes above detailed, I then add from two to six per cent. (preferably six per cent.) of a strong solution of caustic soda, about 40 Baum, or potash or milk of lime, and secure a complete oommingling by the ordinary process of stirring. After about twelve hours of repose the sediment'generally known pure, and of a light color.
' as foot-s, containing the remaining impurities, will be completely deposited, and the supermitant oil quite If any turbidity remains it is removed by filtering, and the oil bleached white in the manner and by the process already extensively in use for that purpose.
By my invention I obtain a better quality of oil, having a superior body, and less liable-to become raucid than that resulting from the processes hcrctoibrc in use.
I am aware that my chemical agents have before been used for the purpose of bleaching-oils, and I do not wish to be understood as claiming them, but having now fully described my process,
. What I do claim, and desire to secure by Letters Patent, is-- 1. A cold process for bleaching and refining animal, vegetable,,'and mineral oils, substantially as described. 2. The application of the agents named, or any two of them successively, to the bleaching or refining oils without the use of heat other than that evolved by the chemical reaction.
' OSCAR LOEW.
