Patent US-1877-194841

Primarily a fan which sucks in air from the front and sends it out the back. (Thus classification as USPC 244/73.)
Secondarily, this propulsion system is envisioned on an aircraft or perhaps on a car suspended from a track, perhaps in conjunction with feathering blades which are turned along with the fan to supplement its propulsive force.
(Presumably these latter "feathering-blades, which are turned on their axis, as the fan is rotated, by a central cam" are the reason for classification under USPC 244/72, although someone could argue that these are not exactly "beating wings".)
Inventor location (imputed by HistPat): Henryville, TN, Lawrence county, TN (FIPSloc=47099)
