  Squarelite Cap Lamp Back.JPG - SQUARELITE - Rare brass Guy’s Dropper Squarelite cap lamp, 4 in. tall to top of water door, 2 in. cube top, 2 3/4 in. dia. reflector, marked on side of lamp in shield SQUARELITE PAT. MAY 26-14 SEPT. 19-16 OCT. 17-16 and GUY’S DROPPER PAT. 5.26.14 – 9.19.16 with ON and OFF on top, with hexagonal base and sidebraces, ex-Doc Kraft collection  [The Squarelite is a Guy’s Dropper product manufactured by the Shanklin Mfg. Co. of Springfield, IL.  However, the Squarelite with its unusual cube shaped water tank versus the usual cylindrical tank on most lamps, coupled with its rarity makes it a very desirable lamp for collectors.  For such a rare lamp, it’s also very unusual in that it is known as a cap lamp, a supervisors-style lamp with hook and handles (examples are shown in my hand lamp pics), a hanging hand lamp with a bail and hook, and a stick lamp.  It was patented by George R. Shanklin as patent No. 49,782 on Oct. 17, 1916.  The Squarelite cap lamp as shown here has three patent dates stamped on them: May 26, 1914, Sept. 19, 1916 and Oct. 17, 1916.  The two earlier patents were issued to Frank Guy, the first for an acetylene lamp and the second for the water dropper feature that made the Guy’s Dropper famous.  A noticeable variation of Squarelite lamps is the strengthening braces soldered to the sides of the water tank.  Later versions of the lamp have these braces (as noted here) obscuring part of the Squarelite shield on the side to correct a significant problem with the strength of the water compartment.  The cap lamp model has four basic variations: (1) with or without side bracing; (2) round or hexagonal base; (3) nickel-plated or brass; and (4) with or without wire cap braces.  As shown, this cap lamp is all brass, has the side braces and hexagonal base, and did not have cap braces.  See Gaska, Eureka #4, pp 21-24]
