Publication: Privately printed for R A Dietz Company, 1917, N P
11 7/8" x 13 7/8" sheet, printed in black and white on two sides, illustrated. One side shows twelve lanterns and Theglobes, plus centered pictures of the factories located in New York City and Syracuse, New York. The New York City facility is over 84,000 square feet, while the Syracuse facility is over 184,000 square feet. The other side shows sixteen lanterns and driving lanterns. All kerosene lanterns employ one of three distinct types of construction: Hot-Blast, Cold-Blast, or Dead-Flame. Cold-Blast and Hot-Blast are tubular lanterns. In them, the kerosene vapor mixed with air, in proper ratio, composes the burning mixture. The burner acts as a carburetor to which the side tubes convey properly controlled air in regulated volume. The result is perfect combustion and bright, clean light. A cold-blast lantern, easily the most efficient of all, is constructed so that only fresh, cold air enters the tubes, while the spent air is diverted and expelled. Hot-Blast lanterns permit a portion of spent air to recirculate through the tubes. Cold-Blast lanterns provide about twice the brightness of hot-blast lanterns. Nineteen of the pictured lanterns are of the cold-blast type. Folds to approximately 4" x 6" but fully opened makes a nice display piece. Near fine copy.
