Ohmer fare register

The Ohmer fare register was, in various models, a mechanical device for registering and recording the fares of passengers on streetcars, buses and taxis in the early 20th century.

This latter company employed up to 9,000 people at one time and was a major manufacturer of precision equipment during World War I.

[2] It was subsequently renamed the Ohmer Corporation and in 1949, acquired by Rockwell Manufacturing Company.

[4] The site is now occupied by the North Concord/Martinez Station of the Bay Area Rapid Transit system.
