ELECTRIC LIGHTING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 289,590, dated December 4, 1883.
Application filed August 16.1883. x0 model.)
To aZZ whom it may concern.-
Be it known that I, NELsoN S. WHITE, of Canton, in the county of Norfolk and State of Massachusetts, a citizen of the United States, have invented a certain new and useful Improvement in Electric Lighting Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is an elevation, and Fig. 2 a vertical section.
This invention relates to an improvement in the globes or bulbs for incandescent lights.
Many factories are filled with atmospheres of greaterorlessinflammableproperties. Such as employ naphtha or other volatile hydrocarbons for solvents or scourers are notable examples of this class. The picker-rooms of cotton-mills and the bolting-rooms of flouringmills are also conspicuous examples. Inconsequence of this fact, insurance rates are very high, and in many instances prohibitory. Such factories cannot be run by artificial light without great danger. In factories employing naphtha, the vapor of this fluid saturates the floors, creeps through cracks, and flows or is liable to flow everywhere. Open lamps are therefore inadmissible, and even the incandescent electric light glowing tn cacao, if broken, is asource of danger.
essary to ignite hydrocarbon vapor mixed with air exists with an incandescent lamp at a radiating distance from the glowing filament just inside of the glass bulb which holds it, and as The temperature nec- Y this -is a vacuum-bulb it has a constant tendency to crush, and a very slight accident breaks it.
My improvement consists in enveloping the glass globe of an incandescent electric light o with wire-gauze at a distance from the light beyond the radiating-point of an igniting temperature, and thereby preventing danger of inflaming the atmosphere of a factory in the short time which elapses before the filament is burned.
In the drawings, A is the glass globe. B is the wire-gauze envelope. 0 is the incandescent filament. By plating with a white metalsuch as silver, tin, or nickel-the wire-gauze reflection will utilize most of the light and there will not be much loss. It will also be observed that the chances of breakage will be lessened by applying this protector of wiregauze.
I claim and desire to secure by Letters Patent- The combination of the transparent vacuumbulb and inclosed filament of an incandescent lighting apparatus with the wire-gauze envelope O, substantially conforming to the transparent vacuum-bulb, and disposed around the incandescent filament at a point beyond the radiating-point of a temperature of ignition, substantially as described.
NELSON S. WHITE.
