Product Description

Antique Ship Brass Engine Order Telegraph

An engine order telegraph or E.O.T., somtimes called a chadburn, is a communications device used on a ship for the skipper on the bridge to order engineers in the engine room to power the vessel at a certain desired speed. 

Traditional E.O.T.s required a pilot wanting to change speed to "ring" the telegraph on the bridge, moving the handle to a different position on the dial. This would ring a bell in the engine room and move their pointer to the position on the dial selected by the bridge. The engineers hear the bell and move their handle to the same position to signal their acknowledgment of the order, and adjust the engine speed accordingly. Such an order is called a "bell," for example the order for a ship's maximum speed, flank speed, is called a "flank bell."

For urgent orders requiring rapid acceleration, the handle is moved three times so that the engine room bell is rung three times. This is called a "cavitate bell" because the rapid acceleration of the ship's propeller will cause the water around it to cavitate, causing a lot of noise and wear on the propellers. Such noise is undesirable during conflicts because it can give away a vessel's position.

This engine order telegraph is a painstakingly detailed reproduction. It is in excellent condition and looks great with many different types of decor. It would make an excellent addition to any naval or marine collection.
