Description:

FX patents are fractional X patents. This patent is #6715 1/2.

Only about 2000 of the almost 10000 X-patent documents were recovered.

Because of the Patent Office fire in Dec. 1836, little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
