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. Only the patent drawing is available. This patent is in the database for reference only.

Manuscript document providing for the sale of a patent on a furnace for $2020, with the last installment payment being due in 1800.
