NELSON S. WHITE, OF CANTON, MASSACHUSETTS.
METHOD OF PBOTECTING INCANDESCENT'EL'ECTRICLIGHTS.
SPECIFICATION forming part. of Letters Patent No. 314,208, dated March 17 1885.
Application tiled October 13, 1883. (No model.)
To all whom, it may concern,.- l
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 Iin provement in Electric Lighting Apparatus, of which the following is a full, clear, and eXact description.
This invention relates to the method of protecting incandescent electric lights by wiregauze guards. Itis desirable to do this in facor other volatile and infiammable liquids are used, because, if the glass receiver breaks, the explosive atmosphere may ignite; and the invention relates, first, to the method of applying the wiregauze guard; second, to the preparation of' the wire-gauze; third, to its proper relations to the receiver and the contained filament.
ln the drawings. Figure 1 is au elevation, and Fig. 2 is a vertical section,of this improvement.
A is the exhausted glass receiver. a :is its inclosed filaments. a+ and ctare the electric conducting-wires. D is the iixture to which are attached the wires, and into which the neck b of the receiver fits, audvto which the said neck is fastened by the pin b2 and bayonetslot di, or in any other usual and proper way. Bis a flange or disk, which is affixed to the neck b. These parts (except flange or disk B) or their equivalents are common to most forms of incandescent electric lights.
A wire-gauze shield, O, is firmly fastened to a neck, c, which ts the outside of the fiange or disk B, and a flanged collar, d, adapted to hang on the edge of fiange or disk B, engages by a screw-thread or other suitable fastening with the neck c of the gauze shield C.
The wires of the shield C should be tinned or nickeled, or otherwise made of a bright 1i ght-col cred surface, so as to reflect light, and if so treated the light will be about as great in quantity and more diffused and soft than with a naked globe. It will be well also to make a reecting-surface on the bottom of iiange `or disk n, which may be dos@ with tin-fon gillen on, or in any other proper way.
'I find that if' the shield is set out about as ommend this as the best proportion for the distance of parts.
I have contemplated, also, the plating of the wire gauze and flange or disk B with glass, or making said disk'or flange B entirely of glass to enhance the illuminating power, and the manner of doing this will form the subject of further application.
It is obvious that the neck c may be screwed or pinned or otherwise fastened to the flange B without using the collar d. l
The disk or iiange B is of greater diameter than the bulb A, and the neck c of the guard C, which engages with said disk B, is hence large enough to pass readily over the globe A. A
This is a great convenience, as the breakage of the globe can be more readily repaired in such a case than 1t" the gauze envelope be drawn more nearly to conform to the shape ot the glass globe A, as in my former patent.
Having thus fully described my invention, I claim and desire to secure by Letters Patent ot the United Statesl. The flanged collar d, neck c, and guard O, in combination with the flange B applied to an incandescent electric-light xture, substantially as described. f
2. A wire-gauze screen for an incandescent electric lamp disposed around the glass bulb thereof aud of greater diameter than said glass bulb, the wires of which screen have bright retlectingsurfaces of light color, whereby the intensity of the light is reduced, its diffusion enhanced, and :its illuminating value retained, substantially as described.
