of the problems with kerosene lamps was the spilling of fluid when
filling the lamp. On September 29th, 1863 George Henry Lomax of Somerville,
Mass. received a patent for a kerosene drip catcher or raised flange
on the top of the lamp font. The flange was tilted upwards during
the hand finishing of the the font. On September 20th, 1870 Mr. Lomax
received a patent for producing his drip catcher font in a pressure-mold.
The date of this patent was embossed inside on the font, on the outside
of the font or on the base of the each lamp to identify it as a "Lomax
Lamp". Some lamps may also be embossed with words such as "Lomax"
or "Oil Guard Lamp". The "Oil Guard Lamp" trademark
was registered by George Lomax in 1871. These lamps were produced
by the Union Glass Company of Somerville, Mass.
