ELECTRIC LIGHT MOUNT ING Filed Oct. 25, 1937 INVENTOR LOUIS NDER ATTORNEY Patented May 2, 1939 American Electric Lamp Company, St. Louis, Mo., a corporation of Missouri Application October 25, 1937, Serial No. 170,723

Claims.

My invention relates to an electric light mount- 7 ing and particularly to a device of this class which is so constructed as to resemble an illuminating device of the oil burning type such as a kerosene lamp of the kind in general use before the advent of electric lighting. In furtherance of this end the lamp bulb is of such conformation and is so screened that the light therefrom simulates the flame of an oil wick. The semblance of an old style illuminating device is thus maintained both in lighted and unlighted state of the device.

In the accompanying drawing, which illustrates an electric light mounting made in accordance with my invention together with certain modifications in the form of light bulb employed in connection therewith, Figure 1 is a side view of the complete device; Figure 2 is an elevation of the pseudo burner and lamp bulb; Figure 3 is an edge view of the bulb taken at right angles to the position shown in Figure 2; Figure 4 is a side view showing a modification of the bulb; Figure 5 is a view showing the bulb of Figure 4 in connection with the dome; Figure 6 is a side View showing a further modification of the bulb; Figure 7 Ban enlarged section taken on the line l--'l of Figure 6; and Figure 8 is a top plan view of the dome.

Referring first to Figure 1, the numeral 10 indicates the base of a pseudo burner. This base is provided with a boss II to fit the lower end of a chimney I2 and with spring arms I3 to retain the chimney in position on the base. The under side of the base is provided with a threaded hub 14 adapted to engage with an internally threaded collar l5 of the lamp stand. The stand comprises the usual reservoir l6 and foot l'l. Mounted on the base is a lamp socket 18 (Figure 2) to receive the light bulb. The socket is supplied with current by a flexible cord I9. The 0 light bulb 29 is provided with the usual threaded base 2! for engagement with the socket l8. The bulb is flattened, presenting a substantially oval shape when viewed from the side, as shown in Figure 2, and having'approximately the form of an inverted V when viewed from the edge, as shown in Figure 3. Surrounding the socket IB and screening said socket and all of the bulb except its top margin from view, is a brass husk break 22 which I term the dome or shield. It is similar in appearance to the usual husk break surrounding the wick tube of an oil lamp. This dome may be supported in any suitable manner but preferably simply rests upon the burner base so that it can be completely removed, as 5 shown in Figure 2. The top 23 of the dome is provided with an elongated opening or slot 24 to permit the top margin of the bulb to project, as shown in Figure 1, to simulate the flame of an oil wick. In this form the entire bulb is preferably made of clear glass.

In Figures 4 and 5 I have shown a slight modification of the bulb to further imitate an oil lamp by producing the appearance of a wick. In this form the bulb has the same shape as the bulb shown in Figures 1, 2 and 3 except that it is somewhat taller in order to project further above the top of the dome. This bulb has a margin 20' of clear or light transmitting glass which margin is demarked by a darkened border 25, a portion of which projects above the top of the dome to simulate a charred wick.

In Figures 6 and 7 I have shown other means for simulating a wick. In these forms the bulb is like that shown in Figures 1 to 3 except that the apex is provided with a groove 26 in which is cemented a crest 2'1 of asbestos or other heat resisting material which will resemble wicking.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. In an electric light mounting, the combination with a pseudo burner base adapted for engagement with a lamp stand and having means for supporting a chimney, of a socket mounted on said base, a lamp bulb in said socket having its upper portion flattened, and a dome surrounding the socket and bulb, said dome having a slotted top through which the margin only of said, flattened portion projects to simulate the flame of a flat wick.

2. In an electric light mounting, the combination with a pseudo burner base having means for supporting a chimney, a support for said base, a socket mounted on the base, a lamp bulb in the socket, said bulb being so formed as to present a substantially oval shape when viewed from the side and an inverted V-form when viewed from the edge, and a dome mounted on the base, said dome concealing the socket and the lower portion of the bulb, said dome having a slotted top through which the upper margin of the bulb projects to simulate the flame of a flat wick.

3. In an electric light mounting, the combination with a pseudo burner base adapted for engagement with a lamp stand and having means for supporting a chimney, of a socket mounted on said base, a lamp bulb in said socket having its upper portion flattened, wick simulating means on the upper part of said bulb, and a dome surrounding the bulb, said dome having a slotted top through which the margin of said flattened portion projects to display said wick simulating means. v

4. In an electric light mounting, the combination with a pseudo burner base adapted for engagement with a lamp stand and having means for supporting a chimney, of a socket mounted on said base, a lamp bulb in said socket having its upper portion flattened, said flattened portion being provided with a light transmitting margin demarked by a darkened border simulating charred wick, and a dome surrounding the bulb, said dome having a slotted top through which the margin of said flattened portion projects a sufficient distance to display the edge of the darkened border.

5. In an electric light mounting, the combination with a pseudo burner base adapted for engagement with a lamp stand and having means for supporting a chimney, of a socket mounted on said base, a lamp bulb in said socket having its upper portion flattened, said flattened portion having secured to its apex a crest of material representing a wick, and a dome supported on the base and surrounding the bulb, said dome having a slotted top through which the margin of said flattened portion projects.
