The Glow Night Lamp For all-night use, as in bedrooms, sick chambers, halls, bathrooms, nurseries, staircases, etc., a large flame is not necessary, in fact a comparatively small flame is more desirable. It is also desirable that the lamp for the above purposed shall be capable of burning for a long time without refilling or attention, without danger and without emitting any odor. The lamp is made entirely of glass and is the only lamp in the world using a glass burner. It is manufactured in two styles and in several colors. . . The main frature of the lamp is the burner. The oil (kerosene) is vaporized in the top of the bulb, and as glass is a poor conductor of heat part of the buld is always cool and any excess of vapor formed at the top condenses and falls back down the tube into the lamp, thus avoiding any odor. A metal burner, being a good conductor of heat, vaporizes the oil in too large a quantity, and only too often forces the unconsumed vapor into the air, producing an unpleasant and unhealthful odor, dangerous to the sick. The Glow Lamp will burn over one hundred hours with one fill of oil, costing little over half a cent. It can be burned ten to twelve hours every night for a year with 35 cents' worth of kerosene oil. The retail price being 25 cents, makes it a ready seller to all classes of people. The Glow Night Lamp is patented in the United States and different countries of Europe. {2063} |
