Carbide Cap Lamps

Imperial Xray RSide.JPG - IMPERIAL JUSTRITE XRAY - Rare special-edition nickel-plated brass Justrite X-Ray lamp, stamped on bottom MARTIN HARDSCOG CO. PITTSBURGH, PA. with IMPERIAL in center, ca. 1919-1920, the Imperial marked lamps are only known in nickel plate with short rib bottoms and polished brass reflectors, with spare bottom, ex-Bob Schroth collection [At one time, Hardsocg was the largest single manufacturer of mining tools and supplies in the world. It's almost impossible to collect mining artifacts and not have something in your collection by Hardsocg. After years of blacksmithing and working in the coal mines of Iowa, in 1878 Martin Hardsocg started his company in Avery, IA to manufacture mining tools. In 1885, he moved the company to Ottumwa, IA and in 1891, the Hardsocg Manufacturing Co. was incorporated with him as president. Within a few years the company had dramatically expanded and owned and operated other companies specializing in mining equipment. This is one of two special-edition lamps manufactured by Justrite with the Xray lamp for other companies. The other is the Fulton Xray shown elsewhere in my cap lamp pics. Both are very difficult to find. The spare base is an interesting item. The bottom is very lightly stamped with a Jiffy marking. Unless one looks closely, it appears unmarked. My good Alaska friend Neil Tysver conjectures that the base was a mistake during manufacture, noting that the bases are stamped one-piece brass, either marked or unmarked, until the connecting ring is soldered on to complete the screw-on base. The Jiffy lamps did not sell well so there was likely a large inventory of marked but unstamped parts. It’s conjectured that a Justrite worker thinking the base was unmarked and, not noticing the faint marking on the bottom, placed the piece in the XRay bottom press, soldered on the threaded connecting ring and created an XRay bottom with a Jiffy marking.]
