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.

A brass navyphone recovered from a wreck of a Royal Navy armoured cruiser by a Dutch diver in the modern era may loosely be taken as an example.  Like other British navyphones, it was supplied by the Graham company, and was probably identified by [[Admiralty Pattern Number]] (an "1814" on this one may be such, but I can find no reference to such a model).
This article seems to have been portable, with a hinged carry handle on its top, a cable gland at the bottom, and a single push lever labelled "Press to Speak".  You can see by the design of the push-to-talk lever that it rotates a capsule of carbon granules within the housing, as in the [[Pattern 1855 Navyphone]].  The front round aperture is the microphone through which the local user would speak; it may have been protected by a light mesh which corroded away before restoration work began.  The brass horn emerging from the back is where the remote speaker's voice would emanate, its geometry helping as much as possible to amplify the volume.

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, but we may guess that the example shown above was typical.

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

circa 1900
Unknown "Navy'Phone" (back)
Unknown "Navy'Phone" (inside)

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.

A brass navyphone recovered from a wreck of a Royal Navy armoured cruiser by a Dutch diver in the modern era may loosely be taken as an example. Like other British navyphones, it was supplied by the Graham company, and was probably identified by Admiralty Pattern Number (an "1814" on this one may be such, but I can find no reference to such a model).

This article seems to have been portable, with a hinged carry handle on its top, a cable gland at the bottom, and a single push lever labelled "Press to Speak". You can see by the design of the push-to-talk lever that it rotates a capsule of carbon granules within the housing, as in the Pattern 1855 Navyphone. The front round aperture is the microphone through which the local user would speak; it may have been protected by a light mesh which corroded away before restoration work began. The brass horn emerging from the back is where the remote speaker's voice would emanate, its geometry helping as much as possible to amplify the volume.

British Patterns

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, but we may guess that the example shown above was typical.

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]

Issues with rain, wind and spray were solved in 1907 by a "damp-proof" model (of unstated type; it was one of those compatible with motor generators, so perhaps 2140A) which was rigorously tested by pouring buckets over it and immersing them in water for 24 hours.[3]
