The illustrations and descriptions of crazy flying contraptions that people applied for patents on (sometimes successfully) are fantastic. I managed to find one of the actual patents for a machine mentioned in the article that’s powered by birds. I think the technical drawings in the patent are even better than the illustrations shown here. Check it out. It’s powered by eagles!
Here’s how the article describes that invention:
From gay Paree comes Edouard Wulff, with a patented scheme for flying by means of “eagles, vultures, or condors.” True to the instincts of his native city, he fits out his birds with “corsets,” the specifications of which as to trimmings, binding, etc., are carefully set out.
By a strange oversight for one bred in the city of fashions, he fails to state what is the latest mode of wearing the feathers on his motors. With wise foresight he has provided for two aeronauts, one on top among the birds and the other below to steer the craft. This is sensible; a man busy prodding up a dozen uncouth and bewildered condors wouldn’t have much time for steering.
Not all of the inventions are outrageous in hindsight. The article takes a mocking tone at a proposed airship so big it has several floors and resembles a hotel, but of course we have multilevel jumbo jets today, some with luxury approaching that of hotels, so it wasn’t so far fetched.
Most of the invention descriptions in the article are too vague for me to find the original patents (if they truly even reached the application stage), but you can find a lot of this kind of thing using Google’s patent search engine. Here is a link to search “flying machine” or “airship” with results displayed visually in chronological order.
