Patented Apr. 7, 1931 UNITED STATES PATENT OFFICE KURT WIEGAND, OF BERLIN, GERMANY, ASSIGNOR TO GENERAL ELECTRIC COMPANY,
A CORPORATION OF NEW YORK ELECTRIC-LIGHTING TUBE Application filed October 21, 1927,
The present invention relates to electric lighting tubes of the kind wherein the electrode container is enclosed in a casing.
In my copending application, Serial No. 226,994, filed October 18, 1927, there is described an electric glow tube, the electrode containers of which are enclosed in a metal casing connected to earth for the purpose of reducing the perforation voltage and having a small space requirement, with the interposition of a non-hydroscopic insulation, advantageously with the interposition of glass bodies. In accordance with the present invention the same purpose is obtained, how- With the omission of a specially made and to be attached metal casing, by the use of an insulating body, say of porcelain, en'- closing the electrode container and which on the outside has a tightly adhering metal coat- The metalcoating is obtained in any desired manner, for example by the squirting on of liquid metal or in a galvanic way, and gives in the same manner as the former metal casing, the possibility of applying an earth connection to the electrode container.
In order to easily attach the box-like insulating body to the electrode container and to be able to also easily inspect the latter, the exteriorly conductively formed insulating i body. consists advantageously of two cups of approximately semi-cylindrical shape engaging with each other and clamped by means of projecting noses. The screws serving for the clamping fast of the two cups of the insulating body can at the same time be v is connected to 'COIltBJIlGI 1s in this case enclosed by a casing- 6 onto the cable used for the connecting up of the earth connection,
In the drawing is shown an example of construction of an enclosed electrode container of my invention, in longitudinal section in Figure 1 and in cross section in Figure 2.
n the forms of construction shown in the main patent the electrode container b attached to the end of the glow tube a has in the interior a sheet metal electrode 0, which the cable d. The electrode say of porcelain, which like insulating body,
one end by the metal cap 1 set is closed off at rubber cap 9 put onto the glow tube a. The,
casing-like insulating body consists of two approximately half-cylindrical cups 7: 'n placed together and having interlocking parts comprising the nose-like projections 0 attached to cup 11 which engage in corresponding recesses on cup n and the lugs p attached to cup n which engage the cup n from the outside. Both cups n, n are further tightly clamped to each other by the screws 9. The entire outside surfaces of both cup parts, W, n of the casing-like insulating body are provided with a tightly'adhering metal coating 1', which is connected to earth in a suitable manner and advantageously by means of the clamping screw 1.
What I claim as new and desire to secure by Letters Patent of the United States, is,-
1'. An'electric discharge device having an electrode container, an insulating sheath around said container, and a metallic coating on the exterior surface of said sheath.
2. An electric discharge device having an 1 electrode container, an insulating sheath around said container, said sheath being formed of a plurality of separable components, and a metallic coating on the exterior surface of said sheath.
3. An electric discharge device having an electrode container, an insulating sheath 'around said container, said sheath consisting of two similar sections and a metallic coating on the exterior surface of said sheath.
4. An electric discharge device having an electrode container, an insulating sheath around said container, said sheath being formed of a plurality of separable components, means on said components for holding said components together to form said sheath, and a metallic coating on the exterior surface of said sheath.
In witness whereof, I have hereunto set my hand this 6th day of October, 1927.
