A Navyphone is a rugged type of telephone made specifically for shipboard applications using short-range circuits. For some time, the Royal Navy called these "loud-speaking telephones", but the word "navyphone" was coming into usage as early as 1902.[1] They considered them as being slightly different to long-range telephones.
Form Factor
Navyphones varied considerably in their physical details, not all of them resembling a conventional telephone. Some resembled intercoms, and some were rather comical in appearance with trumpets or large horns in front or to be clopped over one's ears as though sharing a secret with a sunflower. Most were to be mounted on a bulkhead or other convenient vertical surface.
British Patterns
British navyphones were supplied by the Graham company, and identified like many tools of the Royal Navy: by Pattern numbers. Most were in watertight metal cases with receivers at the back with diaphragms facing the back of the instrument, projecting into trumpets which carried the sound out to the side. The transmitter was placed in front and could be revolved by hand although no clear description is offered of the plane of rotation.
They were most often battery-powered, initially, powered in pairs off six pattern 1453 cells in a pattern 1704 battery box until the Lord Nelson, Bellerophon and later classes in which they were powered by a motor generator.[2]
