Patent US-1852-pj
800' Aerial Locomotive powered by steam propellers and carrying abundant cargo
although Porter filed over a hundred patents and did design an airship as early as 1835, AND did attempt to open a NY-CA transit line (!!), it's not clear that he ever filed a patent for his airship; 1952 date given here probably refers to an exhibition and/or two pamphlets he published in that year
Porter: "As Fulton experienced some difficulties in securing the patent, on account of the want of originality, I have no hesitation to offer, and promise, at least, an undivided half of my claim to the patent, to any person or company who will be at the expense of building such a balloon on a scale sufficient to test its utility."
