With their manufacturing feet firmly under them making doorbells and bicycle components, the Rockwell brothers of New Departure Bell Company of Bristol, Connecticut ventured into the new automotive field. In 1904, they produced an automobile (the Haupt Rockwell) and then in 1907, the Rockwell Taxi Cab. In 1911, automobile production ceased.

The Rockwell Cab. Originally painted black, but the story goes that Mrs. A.F. Rockwell suggested a colour change to yellow, thereby creating the "Yellow Cab".
A subsidiary of New Departure later operated these "Yellow Cabs" in NYC.
