I am related to the person who invented the first automobile odometer which was on the steering wheel. (No dashboards back then). Does this document have any value? Patent number 1914424 is in my possession and in mint condition along with the drawings.
Since you added the patent number I'm updating this answer. The patent US1914424A was invented by Earl C Hendel and granted on September 3, 1932. It would have expired 17 years from that date. Once a patent expires, anyone can use the technology described by the patent. Thus there is no more licensing income likely available. I checked and this was Earl Hendel's only patent.
If you have the original patent document itself, it is possible it has some historical value or perhaps value as a collectable, but that is well beyond the scope of this site so we can't help you with that.
