History, Kerosene Lamps

After the invention of the oil lamp design and production of oil in 1800, people had the opportunity to use these bulbs to do outside. The wick oil lamp, a glass ball and the amount of airflow around the wick control and to protect the flame. But there was much work to do outside when the lights were easily broken. Therefore, a much stronger away from the light source was needed. Thus came the introduction of a kerosene lantern, also known as the hurricane lantern. This is a robust version of the lamp, which was designed to be portable. These consist of a metal base, which is the fuel and break this side tubes to prevent the crystal ball to support security, too.

These lamps have many applications in the early 1800s to 20 Century. Were used for lighting homes and barns, horse-drawn carriages to light, ships, cars and even early automobiles.
There were different kinds of kerosene lanterns made. One was the dead flame lantern. These were designed to eliminate or minimize the draft which reached the flame. These are also known as non-tubular lanterns. They consisted of a series of baffles inside the top, above the globe, and a series of bottom draft holes, that were positioned so no top draft, or wind could blow directly on the flame. These were often used by the railroads as signaling lights.
Another type of kerosene lamp was the tubular lamp. These contain a ducting system to stabilize and enhance the draft of air reaching the flame, creating a stable, wind resistant flame. They are further divided into the "hot blast" and "cold blasts" styles.
The "hot blast" lanterns are constructed to supply air into the base of the lantern, which is heated by the flame. A portion of the hot air rises into the canopy over the globe, and is pushed by a downdraft through the side tubes to the air chamber beneath the burner supplying the flame. Hot blast lanterns produce a yellow flame.
The "cold blast" lanterns are constructed so the supply of air through the side tubes, does not mix with heated air from the flames. The flame is supplied with fresh air, both through the globe plate and the side tubes. This produces a white flame, and twice the volume of light as a "hot blast" lantern. The most famous manufacturer of tubular lamps, R.E. Dietz, still manufactures lamps today, although his company has moved to Hong Kong and China.
The use of kerosene lamps decreased during the depression. Today most uses for kerosene lamps are supplied with flash lights, and outdoor lights. Kerosene lamps are often collectors items.
