Would like to look up Cox patents at the U.S. Patent office.  Anyone know any Cox patent number(s)?  Apparently any patent prior to 1975 can only be searched by number, issue date or US Classification.

There's some listed here: https://www.coxengineforum.com/h24-instruction-sheets#patents

If you track down more, please let me know as I'd like to add them to the list.

I don't believe there were any patents on the engine designs. There was nothing unique about the designs. Cox was successful in manufacturing to a consistent quality and good price.
