- Patent Model of Marine Signal Lantern, 1863 - This marine lantern was designed to burn oil. An opaque metal shade could be moved to expose and block its glow. Moveable red and green glass shades are its most innovative feature, which served two purposes. They allowed the lantern to act as a communications device, to send messages between ships--and as an anchor light, to avoid collisions between vessels.
