' INCANDESCEN'I' LAMP Filed March 25, 1951 lnvenior 7 L a/Zare 5 030m! 12's A tlorney Patented May 24, 1932 UNITED STATES PATENT OFFICE THEODORE KOWVALLIS, F READING, PENNSYLVANIA INCANDESCENT LAMP Application filed March 25, 1931.
plication Serial No. 427,338, filed February- 10, 1930, on the same subject matter.
The principal object of this invention is to provide an incandescent lamp of the luminous gas type, wherein the electrodes are mounted in such a manner as to produce a uniform discharge of the gas.
Other important objects and advantages of the invention will become apparent to the reader of the following specification and claim.
In the drawings Figure 1 represents a side elevational view of the lamp.
Fig, 2 represents a vertical sectional View through the lamp.
Fig. 3 represents a sectional View taken substantially on the line 33 of Fig. 2.
Fig. 4; represents an enlarged fragmentary sectional view through the lower portion of the lamp.
Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents the negative threaded part of the base, generally referred to by numeral 6, while numeral 7 represents the usual positive contact. This contact 7 is insulated by the material 8 from the negative jacket 5 and has alead 9 extending there from to the helical filament 10 situated in the pocket 11 at the lower end of the inner bulb 12.
This coil 10 terminates at the lower end of the pocket 11 and the inner side of this pocket, as well as the outer side of the bulb 12 is provided with a mirror or reflecting surface 13. In spaced relation with respectto the bulb 12 is the outer bulb 14., and within this space 15 between the bulbs any suitable gas may be present.
Extending from the jacket 5 is the support 16 through which the coiled element 17 is secured, the same circumscribing the neck portion of the inner bulb 12.
Obviously, the discharge of current will take place between the electrode coil 10 and the negative coil 17 and due to the disposi- Serial No. 525,235.
tion of the coil 17, this discharge will be uniform so that the incandescence will be of substantially the same efliciency at all points.
While the foregoing specification sets forth the invention in specific terms, it is to be understoodthat numerous changes in the shape, size and materialsmay be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having thus described my invention, what I claim as new is A lamp bulb of the character described comprising an inner bulb, an outer bulb spaced from the inner bulb, said inner bulb being provided with a pocket at its outer end, the inside of the pocket being provided'with a reflecting surface, the outside of the inner bulb being provided with a reflecting surface,
an electrode disposed around the inner end portion of the inner bulb, an electrical conductor extending longitudinally through the inner bulb and projecting into the pocket, and a spiral electrode located in the said pocket and connected to the said conductor.
In testimony whereof I aflix my signature.
THEODORE KOWVALLIS.
