A beautiful example of technology and art from 100 years ago. This carbide bicycle latern has red port jewel and a green starboard jewel. The port and starboard lights are taken from marine navigational signals. Wikipedia says: The conventional format of producing acetylene in a lamp is by putting the calcium carbide in the lower chamber (the generator). The upper reservoir is then filled with water. A threaded valve or other mechanism is used to control the rate at which the water is allowed to drip onto the chamber containing the calcium carbide. By controlling the rate of water flow, the production of acetylene gas is controlled. This, in turn, controls the flow rate of the gas and the size of the flame at the burner, (and thus the amount of light it produces). T were carbide lamps for bicycles, horseless carriages, miners lamps and many more types. This is complete lamp and you can see the clamp on mechanism for clamping onto a verticle pole is all t The glass front lens is in great shape as are the red and green side jewels. The nickel plating is a little thin on the bottom container and other places as you can see in the pictures. Inside the lower container one of the plates is rusted but still t T is an indentation in the back of the upper reservoir. The bottom has patent dates and the latest is 1899.
