PRINCIPLES OF LANTERN CONSTRUCTION
Most kerosene lanterns embody one of three
distinct types of construction: Hot-Blast, Cold Blast, or Dead-Flame. Dietz
makes all three types to fill every lighting requirement.
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. Result: 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 provides about twice the brightness of hot-blast.)
Dead-flame lanterns take in fresh air through the baffles at bottom, expel spent air at
top. Hot and cold-blast lanterns produce much more light than dead-flame type.
HOW TO GET THE MOST
FROM YOUR LANTERNS
Correct maintenance of lanterns will provide
lower lighting costs, brighter lighting, long time between fillings, longer lantern life,
greater reliability and more certain protection of the public. Follow these simple
