FX patents are fractional X patents. This patent is #8536 7/8. This patent was reissued as patent # RX37.
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. Only the patent drawing is available online.
