Additional Information

The “telephonemeter” (pulse counter) was invented in 1905, at a time when making a phone call was very expensive. It was common to have it in Post Offices, Hotels, and other public services, where telephones were available as a service. This “clock” only counts twelve minutes and has a single lever with three positions.
