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. Only the patent drawing is available. This patent is in the database for reference only.
“For an improvement in the Wheat Fan; George Hoffman, Frederick County, Maryland, August 21.
The general form of this fan is the same as those in common use, but it differs in a variety of particulars, which it would be difficult, if not impracticable, to explain without a drawing. The mode of communicating motion to some of the parts, the wind-wheel, and the riddles, offer certain peculiarities, which are described and claimed by the patentee.”
