INCANDESCENT ELECTRIC LAMP.
SPECIFICATION forming part of Letters Patent No. 500,078, dated June 20, 1893. Application filed April 5, 1893. Serial No. 469,188- (No model.)
To all whom it may concern.-
' Be it known that I, WILLIAM EMEEY NICK- ERsoN, of Cambridge, in the county of Middlesexand State of Massachusetts, have invented a new and useful Improvement in In candescent Electric Lamps, of which the following, taken in connection with the accom panying drawing, is a specification.
My invention relates to incandescent electric lamps of that class in which the neck of the lamp globe is closed and the leading-in wires supported by a cement plug.
It consists of a device by which the heat from the incandescent filament is prevented from aifecting the cement plug by which the lamp globe is made air tight.
In the accompanying drawing I represents the glass globe of an incandescent electric lamp, J the filament attached atjjto theleadi'ng-in wires K K. g
L is a disk of mica or other suitable substance resting upon a shoulder Zformed in the neck of the lamp globe, and serving to support the fusible cement plug M, and the leading-in wires K K.
N is a disk smaller but similar to L and rests upon the shoulder It also formed in the neck of the lamp globe. The space between the disk II and the disk N is occupied by the ing-in wires K K, disk II, cement plug M, the
disk N, and the filling of sand 0, substantially as and for the purpose set forth.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 3d day of April, A. D. 1893.
WVILLIAM EMERY NICKERSON.
