A ship’s engine order telegraph () was a device with a round dial and a handle on the bridge of a vessel that was used to signal the engine room to set a certain speed. Movement of the handle on the bridge activated a similar pointer and an alarm bell in the engine room to tell engineers to adjust the ship’s engine to the speed indicated: Full Ahead, Half Ahead, Slow Ahead, Slow Astern, Half Astern, Full Astern. Other settings are: Stand By, Stop, and Finished With Engine. This telegraph is on the Delta Queen, an American paddle-wheel riverboat launched in 1926 that has since become a floating dockside hotel in Chattanooga, Tennessee, USA.
