\ INCANDESCENT ELECTRIC LAM P.
SPECIFICATION forming part of Letters Patent No. 500,077, dated June 20, 1893.
Application filed April 5, 1893. Serial No. 46 9,180. (No model.) 7
To all whom it may concern:
Be it known that we, WILLIAM EMERYNIcK- ERSON, of Cambridge, county of Middlesex, and EDWARD EGB'ERT CARY, of Boston, in the county of Suffolk, State of Massachusetts, haveinvented a new and useful Improvement in Incandescent Electric Lamps, of which the following, taken in connection with the accompanying drawing, is a specification.
Our invention relates to that class of incandescent electric lamps 'in which the neck of the lamp globe is closed by, and the leadingin wires pass through,a fusible cement plug.
It consists in a device which prevents the leading-in wires from transmitting the heat from the incandescent filament and the hotter parts of the lamp into the fusible cement plug, and another useful purpose set forth hereinafter.
In the accompanying drawing J represents the glass globe of an incandescent electric lamp, K a disk of mica, porcelain or other suitable substance which serves as a support for the leading-in Wires L L and for the cement plug M.
N is the filament attached at n n to the leading-in wires L L.
O is a disk similar to but smaller than the disk K, and is located in the neck of the lamp between the disk K and the filament, and
crimped or helical form for the purpose of increasing the length of wire between the fila ment N and the cement plug M, in order that the amount of heat conducted by the wires L L from the incandescent filament N to the cement plug M may be reduced to a minimum. The convolutions further serve to keep the disk R in position and prevent it from moving toward the disk K.
I claim- In an incandescent electric lamp, the combination of the glass lamp globe J, disk K, cement plug M, and filament N; with. the leading-in wires L L, said wires having convolutions between the filament N and the cement plug M, substantially as and for the purpose set forth.
In testimony whereof we have signed our names to this specification, in the presence of two subscribing Witnesses, on this 3d day of April, A. D. 1893.
XVILLIAM EMERY NICKERSON.
EDWARD EGBERT CARY. Witnesses:
