JF Ptak Science Books Post 1746
This is one of the most appealing sets of "flying" or manned aerostation patent drawings that I have seen in the USPTO collection for the 19th century. The machine is a human-powered ornithopter, applying the structure of a human against that of a bird, and outfitting the flyer accordingly to combat their human weaknesses as adapted to bird flight. Needless to say, and in spite of the beauty of the thought, this arrangement was destined to deep failure. (The patentee, Reuben Jasper Spaulding, of Rosita ("Little Rose"), Colorado (south of Pueblo), may have been the same Reuben J Spaulding who made the first gold strike on the Blue River on Colorado's Western Slope in 1859.) Spaulding's design is interesting also for the balloon device for getting the aero pioneer off the ground.
[Source: Google Patents (and also for the extensive annotations for the images).] I note that there was a model constructed for this patent--I'd love to see that.
And along this same vein of ornithopter-y thought is this, another American solution to the man-bird-mechanical-flight continuum, produced a dozen years earlier--it is similar, though not nearly as glorious (at least in presentation) as the later Spaulding effort:
