T. A. EDISON. INGANDESGENT ELEOTRIG LAMP.
No.'351,856. Patented Nov. 2, 1886.
UNITED STATES PATENT OFFICE.
THOMAS A. EDISON, OF LLEWELLYN PARK, NEW JERSEY.
INCANDESCENT ELECTRIC LAMP.
SPECIFICATION forming part of Letters iatent No. 351,856, dated November 2, 1886. Application filed October 5, 1886. Serial No. 215,342. (No model.)
To all whom, it may concern:
Be it known that I, THOMAS A. EDISON, of Llewellyn Park, in the county of Essex and State of New Jersey, have invented a certain new and useful Improvement in Incandescent Electric Lamps, (Case No. 679,) of which the following is a specification.
The electric lamp which I generally prefer to use is one in which the carbon filament is inclosed in a hermetically-sealed exhausted glass globe, made in two parts of glass hermetically joined together, the lower part of the globe being fashioned into a neck, so that it may be readily placed in a suitable holder or socket, as more fully described in Letters Patent ot' the United States No. 230,255, granted to me. In some locations, however, may be desired a simple lamp capable of being suspended or swung. divested of all parts not necessary, in order that it may be cheaply made.
The object of this invention is to furnish such a lamp; and to that end it consists in the features more particularly set forth and claimed.
The accompanying drawing represents such a lamp.
A is the glass inclosing globe, preferably made round, but with an aperture left at the point a.
B is the carbon filament, attached to clamps I) b, on the terminals of the metallic conductors l 2.
cis a glass disk, in which are sealed the conductors 1 2. It may or may not be provided with a handle of glass, 0,
The wires 1 2 being sealed in the disk and the carbon properly attached, the disk is passed into the globe through the aperture, the edges of which are then hermetically sealed upon the disk. The globe is exhaustedand sealed off in the usual manner, or as described in my Patent N 0. 230,255, before referred to, and the result is an exhausted hermeticallysealed lamp, with the inclosing-chamber made in two glass parts hermetically joined together without the tubular inside stem or part of said patent, and ofsimpler construction than thelamp described in said patent.
\Vhat I claim is- The incandescent electric lamp having, in combination, a glass inclosing-globe composed of the glass chamber and disk hermetically joined together, the incandescing conductor inclosed within such globe, and the metallic conductors leading to such incandescing conductor and passing through and sealed into the glass dish, substantially as set forth.
This specification signed and witnessed this 30th day of September, 1886.
