Oilwick Lamps

Trethaway Surveyor Hand Lamp with Handle.JPG - TRETHAWAY BROS. LARGE UNMARKED SURVEYORS LAMP - Large tin surveyors/hand lamp, unmarked Trethaway Bros. with brass fill cover, 2 5/8 in. base dia. and 2 3/4 in. high to top of font cylinder, 6 1/4 in. high to top of burner tube, 9 in. high to top of wick tube cover/handle, double-banded font, 5 in. long handle (This is the largest surveyor/hand lamp in my collection. While the unusual oil wick lamp shown here is often referred to as a surveyors lamp, there is no evidence that the lamp was actually used as such. How this nomenclature came into being is unknown, but these mining lamps which were designed to be attached to a hat or carried by hand will probably always be called surveyors lamps. Marked lamps of this type were manufactured by a few companies including D. D. Williams, Crown (see examples elsewhere in my pics), Trethaway Bros. and T. B. Bickerton. Other manufacturers may have made unmarked varieties. The only patent granted for this style lamp was issued to David D. Williams of Wilkes-Barre, PA on Jan. 10, 1882 as No. 252,284 but all the examples tend to follow the features of the Williams patent. See Johnson, Eureka #16, pp 24-29) Check out the Williams patent later in my pics.
