JF Ptak Science Books Quick Post [Part of the History of Patents series.]
Looking for (workable) patent models/templates for folding paper chess piece carriers (there are such things) I found these game patents, all of which are based to some degree on chess. I’m not sure why you’d play them if you could simply just play chess, but, well, they do seem like an interesting diversion, though from the little I read on actually playing each of the games they seem somewhat hollow. They are, however, pretty-looking things if not pretty-playing.
Each image is clickable back to the U.S. Patent and Trademark Office where there is an accompanying text which sometimes gives enough information so that you could play the game.
