J. V NI'G"HOLS. ELECTRIC INGANDE'SOENT LAMP.
Patented Nov 28, 1882..
UNITED STATES PATENT OFFICE.
JOSEPH V. NICHOLS, OF BROOKLYN, ASSIGNOR TO THE UNITED STATES ELECTRIC LIGHTING COMPANY, OF YORK, N. Y.
ELECTRIC INC ANDESCENT LAMP.
SPECIFICATION forming part of Letters Patent No. 268,269, dated. November 28, 1882.
Application filed March 14, 188-2. (No model.)
.To all whom it may concern 7 'Be it known that I JOSEPH V. NICHOLS, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Electric Incandescent Lamps, of which the following is a specification, reference being had to the drawings accompanying and forming a part of the same.
Myinvention relates to the manufacture ot'incandescent electric lamps which have a globe or receiver composed entirely of glass, into which the'metallic conductors supporting the carbon or its equivalent are sealed.
My improvements are directed more particularly to that part of the process of manufacture which consistsin bringing together the several parts to form a complete lamp, the object of the improvements being to lessen the cost of production and facilitate the manufacture of the lamp.
One process of manufacture, which has been. followed in certain cases, consists in forming separately a globe and supporting-base, both of glass, then sealing into the supporting-base the' wires for conducting the current into the lamp, then mounting the carbon, and, lastly, joining the base and globe, and exhausting the latter. In this process both the globe and the base areformed by the glass-blower, and require much time and the exercise of the highest skill in their production. Theseobjections are avoided by the process of manufacture which forms the subject of my invention, and which is substantially as follows:
I mold or blow in well-known ways a globe or receiver of any desired shape having an open contractedpart,which Iterm the fneck. The conductingarires for leading the current into the lamp are short lengths of wire, preferably platinum. These I hold in parallel positions, and form or build up about them at one or more points masses of vitreous material, by which they are mechanically united. The method of applying this material to the wires and causing the same to adhere is well known to those skilled in the art, the simplest way being to wind a sufficient quantity of the material about the wires While it is softened by being held in the flame of a blow-pipe. Then one or more of the masses referred to have been applied to the wires, I attach to the latter a carbon conductor and insert the same in the globe.
Then by heating the edge or rim of the open necli and pressing it inward, I weld it to one of the vitreous masses. After this the globe is exhausted by a tube drawn outfrom it, and then sealed.
Referring to the drawings for a more detailed description of the invention, Figure 1 represents a convenient form of receiver. It
is formed in a mold or by simple blowing, and
has a contracted portion, A, which is cut off and left open. An exhaust-tube, B, is formed, in a manner well understood, on the top. The precise shape of the globe or receiver is evidently a matter of taste.
Fig. 2 shows the conductingstrip of carbon C attached to the metal wires F and the'vitreous material D D, which, in this instance, is applied to the wires at two points. The vitreous substance, which I by preference use is that described by me in former patents, notably No. 236,833, as metallo vitreous cement... Glass, however, as commonly made, me y be our ployed.
Fig. 3 represents the lamp complete. In this figure the carbon is shown in its proper position within the lamp, the rim of the neck A has been heated, worked inward, and welded to the vitreous material D that connects the two conductors F F. The receiver being thus completed is exhausted by means of the tube B, and then sealed.
W'hat I claim as my invention is- The method or process of manufacturing incandescent lamps which consists in forming or building up about the conducting-wires one or more masses of vitreous material, mounting upon said wires a carbon conductor, introducing the same into an open globe or. receiver, heating and contracting that portion of the receiveraround the opening, and welding it to one of the vitreous masses, and then exhausting the globe, all substantially as herein set forth. y
In testimony whereof I have hereunto set my hand this 9th day of March, 1882.
