Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
"For a mode of Refining all kinds of Oil, and animal fat; Charles E. Ruggles, New York, July 20.
This being a process which may be performed in secret, and the right of the patentee thereby evaded, we do not publish it."
