Police Call Box

The first police telephone was installed in Albany, New York in 1877, one year after Alexander Graham Bell invented the device. Call boxes for use by both police and members of the public were first installed in Washington, DC in 1883; Chicago and Detroit installed police call boxes in 1884, and in 1885 Boston followed suit. These were direct line telephones placed on a post which could often be accessed by a key or breaking a glass panel. In Chicago, the telephones were restricted to police use, but the boxes also contained a dial mechanism which members of the public could use to signal different types of alarms: there were eleven signals, including "Police Wagon Required", "Thieves", "Forgers", "Murder", "Accident", "Fire" and "Drunkard".
