Hi all, This is a ca 1905 hollow wire lamp "The Pitner Light" from the Pitner Lighting System, made by the Pitner Gasoline Lighting Co. Marion Pitner has a couple patents associated to this lamp; the first overall patent applied for in 1904 and granted in 1905. Later in 1907 and 1909 patents additional patents were granted for parts already installed in this lamp. The lamp is said to produce 600 CP and is gasoline fed. The quality of this Pitner hollow wire lamp is very high, as were also the later table lamps; the Pitner Parlour lamp and also the Pitner (B) lamp. The quality you can see in many Pitner lamp details. Maybe that was a problem competing with several other lighting companies in the 1900,s and 10,s with that high standard of high quality. Around 1915/16 the Pitner company no longer produced lamps and after a factory fire the company ceased in 1916. A thorough clean up was needed and it was also kind of complicated to get a hw functional connector nut. A bit scary having the entire weight of the lamp on the hollow wire connection. I would have preferred a wire hanger for security. The lamp fired up on the first try, and this is a lovely addition to my collection of early American lamps. /Conny 1906/1912 catalogue images (courtesy of Neil McRae)………. 1904 to 1909 Pitner patents..... and the "before"...……..
