Oil-Wick Miner’s Lamp Patent Model
Seybold, William
This oil-wick lamp is a patent model constructed by William Seybold of McKeesport, Pennsylvania that received patent number 90,963 on June 8, 1869. Seybold claimed as his invention “extending the wick-tube upwards, within the lamp-chamber, nearly to the top of the lamp” and “extending the exterior portion of the wick-tube above the top of the lamp” in order to keep lighter oils from making their way up a normal spout due to the motions of a miner’s head.
