Carbide Cap Lamps

GD One Date Top.jpg - SHANKLIN GUY'S DROPPER 1 DATE - Very hard to find one-date Guy’s Dropper brass lamp, early style ca. 1914, early curved stamping on top marked GUY’S DROPPER PAT. MAY 26-14, wrap under narrow spade mount, two-ringed base with bottom marking MANUF’D BY SHANKLIN MFG CO SPRINGFIELD, ILL in oval, rare small brass 2 3/8 in. dia. reflector with soldered brace, ex-Dave Thorpe collection (The Shanklin Manufacturing Co. of Springfield, IL was a prominent producer of miner's carbide lamps with its famous "Guy's Dropper" carbide cap lamp. Designed by Frank Guy, he obtained his first patent in 1910 (#974,054 of Oct. 25, 1910) and two additional patents (#1,097,716 of May 26, 1914 and #1,198,537 of Sept. 19, 1916) while developing a business arrangement with brothers George and Edgar Shanklin to manufacture the lamps. In 1913, the brothers formed the Shanklin Manufacturing Co. to mass produce the Guy's Dropper lamp. The single date Guy's Dropper lamps as shown here are quite scarce. The two-date model shown elsewhere in the photos refers to the 1914 and 1916 patent dates. The war years of 1917-18 substantially increased the demand for carbide lamps as the need for coal and minerals peaked. The Guy's Dropper benefited with this demand with increased production of both the cap and hand lamps. In addition, Shanklin manufactured a Guy's Dropper cap and superintendent-style hand lamp variation known as the "Squarelite," distinguished by the square shape of the lamp top. The Squarelite design was patented by George Shanklin on Oct. 17, 1916 as #49,782. These lamps are scarce and coveted by collectors. As with other carbide lamp manufacturers, the 1920s brought a decline in the demand for acetylene lamps and problems for the Shanklin company. In 1932, the Shanklin Manufacturing Co. was sold to the Universal Lamp Co. where the Guy's Dropper continued in production as a best-selling Universal product until the company ceased manufacturing carbide lamps in 1960.
