Filed Aug.` 25, 1929 2 Sheets-Sheet 2 Patented Nov. 17, 1931 UNITED STATES KOSTI NIKOLOFF, OF DETROIT', MICHIGAN ELECTRIC BULB Application led August 23, 1929` Serial No. 387,978.
This invention relates to electric lamps or bulbs, the general object of the invention being to form the lamp or bulb in the form of l a letter or a number so'that the lamps or b bulbs can be used for forming words and numbers. j
This invention also consists in certain other features of construction and in the combination and arrangement of the several lo parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.
In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in Whichz- Figure l is a front view, with parts 20 broken away, showing a lamp forming the letter B.
Figure 2 is an edge view of Figure 1.
Figure 3 is an end view thereof.
Figure 4 is a section on line 4-4 of Figure 1.
Figure 5 is a view of a lamp made in the form of the numeral 5.
Figure 6 is an edge view of Figure 5.
Figure 7 is an end view thereof.
Figure 8 is a section on line 8 8 of Figure 5.
Figure 9 is a sectional view through a plug.v
As shown in Figures 1 to 4, the lamp A is shaped to form the letter B and in Figures 5 to 8, the lamp is shaped to form the numeral 5. The lamp is entirely formed of glass and each part of the lamp is of rectangular shape in cross section, and each lamp is provided with one or more projections 1 on its rear face through which the ends of the filaments 2 pass. A metal caI 3 fits over each projection and one of the lament ends is connected with this cap. A socket 4 fits over the cap,
with one of its contacts engaging that end of the filament which extends through the center of the projection andI its other contact engages the cap. These contacts are connected with the usual conductors 5. The filaments extend through certain portions of the lamp, as shown at 2', and 2, and said filaments are suitably supported where necessary. Where a number of the plugs are used, asin Figures 5 to 8, a set of filaments 2x is connected with each plug, as shown in Figure 5.
Fromthe foregoing, it will be seen that the lamp is entirely composed of glass and is supported by the plugs so that the lamps can be easily and quickly arranged on a suitable support to form letters ornumerals.
It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.
It is to be understood that changes may be made in the construction and in the combination and arrangement Aof the several parts, provided -that such changes fall within the scope of the appended claim.
An electric light bulb comprising a body, an electric lament in the body, a projection formed on the body and having the terminals of the filament extending through the end and side thereof, a conductor sleeve on said projection and having one of the terminals in engagement there-with, a cap mounted on the sleeve and having an end wall spaced from the end of the projection and provided with a centrally arranged opening, and a contact mounted in the opening and insulated from the cap engaging the other terminal of the filament and cooperating with said ca to form an electrical connection for the lament.
In testimony whereof I affix my signature.
KOSTI NIKOLOFF.
