Baker, Rauch & Lang built the Owen Magnetic after Walter C. Baker purchased the rights to Justus B. Entz's electromagnetic transmission in 1912.

Legal Series -- Richard W. Kellow File: Patent Agreement with Entz (1889) [HK211]

These documents are from envelope 211. They consist of correspondence and agreements relating to Justus B. Entz, who was chief electrician of the Edison Machine Works from 1887 until 1890. The label on the envelope contains the following notation: "Patent Agreement March 15, 1889 Justus B. Entz and Thomas A Edison Royalty to be allowed Mr. Entz for use of certain patents."

US Patent and Trademark Office Patent search site, if anyone can find Entz's patent numbers.

I searched Entz's patents and the three key patents for the magnetic transmission appear to be:

   732,062   filed:  1898  Power Transmission and Control  patent granted: 1903
 1,164,588   filed:  1908  Self Propelled Vehicle          patent granted: 1915
 1,207,732   filed:  1915  Motor Vehicle Control           patent granted: 1916

The electromagnetic double machine transmission in the Owen Magnetic car appears to be based on Entz patent 1,207,732, filed in 1915. — Preceding unsigned comment added by 98.217.200.163 (talk) 00:38, 20 February 2015 (UTC)[reply]
