Three years to the day after I filed the non-provisional patent application with the US Patent and Trademark Office, the examiner has allowed a patent for my Variably Expanding Chain Transmission to issue!

UPDATE: On January 1, 2019, patent number 10,167,055 was issued for Variably Expanding Chain Transmission!
