Compass & Telegraph

A telegraph is an apparatus, usually mechanical, for transmitting and receiving orders between the bridge of a ship and the engine room or some other part of the engineering department. In early vessels, from the 19th century until about 1950, the device usually consisted of a round dial about nine inches (20 centimeters) in diameter with a knob at the center attached to one or more handles, and an indicator pointer on the face of the dial.
