A. ooEroEA'rIoN-or' NEW YORK FOR INGANDESCENT LAMPS AND SIMILAR DEVICES Application filed November 15, 1929, Serial No. 407,533,- and in Germany December 21, 1928.
My invention relates to bases for electric incandescent lamps and similar devices comprising a glass container, or bulb, having an electric-energy translation device such as a 6 filament sealed therein.
lates more particularly 'to bases for larger lamps or other devices and especially to the so-callcd skirted base which comprises a lower portion, usually screw-threaded, which en- 10 ters the socket and an upper portion usually of larger diameterv called a skirt which receives, the lower portion of the bulb neck. Heretofore these portions have been integral. According to my invention they are separated by an insulatingblock, through passages in which the leading-in conductors are threaded and effectively insulated from each other. The upper skirt portion of the base and the lower portion thereof are fastened 20 to the said block. One of the passages through the block is lateral so that ,the leading-in conductor projecting therethrough Y may be conveniently fastened to the lower shell portion of the base. The other passage may be central so thatthe leading-in conduc- Itor projecting therethrough may be united to the center contact carried by the lower shell portion. One advantage of my inv"en-. tion is that the block takes strains occasioned by knocks-and hard usage and thus prevents My invention re-.
ly into which tongues 18 and 19 of the metal portions are punched. Permanent'fastening of these parts may be provided by filling the depressions after the tongues are bent thereinto with suitable cement.
What I claim as new and desire fi) secure by Letters Patent of the United States, is:
1. A base for incandescent lampsand similar. articles comprising an insulating block having passages therethrough for leading- 00 .in conductors and a collar and upper and lower metal shells united to said block and separated by said collar, said upper shell being shaped so that. it may be cemented to a bulb neck and said lower shell being tlyead- 06 ed to engage a socket.
2. A base for incandescent lamps and similar articles comprising an insulating block having passages therethrough for leading-in 1 conductors and peripheral depressions there- 10 in and upper and lower metal shells united to said block and having tongues engaging said depressions, said upper shell bein shaped so that it may be cemented to a. bul neck and said lower shell being threaded to 7| engage a socket.- e
In witness whereof, I have hereto set my hand.

lamp. Moreover, the matter of uniting'th leading-in conductors to their'respective teraninals' is facilitated and theirfinsulation from each other ensured. 7
