Application February 24, 1936, Serial No. 65,312

1 Claim. (Cl. 240-81) My invention relates generally'to lamps and more particularly to an improved type of fixture which is used in connection with incandescent lamps.

One of the objects of my invention is to provide an article of manufacture of unitary construction which has an opaque body portion shaped to simulate a candle stem and a reflecting diffusing surface formed of the same material as the body portion, but permitting passage of incandescent lamp rays.

Another object is to provide an incandescent lamp ray reflector having a translucent body to permit passage of incandescent lamp rays and a depending body portion shaped to simulate a candle stem and formed of the same material as said reflector but having an opaque surface to prevent vision of the structure contained therewithin.

Another object is to provide a candle simulating stem and diffusing shade all formed of the same material having a tubular body portion colored to provide an opaque wall and a translucent shade to permit passage of incandescent lamp rays.

Another object of my invention is to provide a unitary candle simulating stem and reflector surface which is integrally moulded from a plastic compound in which the stem portion is treated to have the qualities of opaqueness, and the reflector surface to have the qualities of translucency.

In the drawing:

Figure 1 is a side elevation of the upper portion of a lamp showing my invention applied thereto,

Figure 2 is a view partly in elevation and in cross-section showing my invention applied to the bracket extension of the lamp,

Figure 3 is a perspective view of my invention.

From the drawing it will be seen that the lamp is provided with the usual hollow pedestal I0 and supporting bracket I I. The bracket is formed of two complemental sections and has a plurality of radially extending arms I2, each of which arms has an extension I3, provided with a flange I4, which is adapted to receive the tubular or sleeve portion of my invention, presently to be described. Secured to the lower bracket section I5, as by threaded bolt i6, is an upright support I'I which carries the usual socket Ila in which is threaded the incandescent lamp I8. Mounted on the bracket i I, is a standard 2D which suitably supports the usual lamp shade 2|. Current supply wires or conductors I9, connecting at one end with terminals of the socket I'Ia extend through the arms I3 and into the hollow pedestal I0, for connection with a suitable plug which communicates with the electric current supply. A suitable switch on the lamp, not shown, controls the current supply to the lamps I 8.

The candle simulating stem and diffusing reflector or shade comprise an opaque body or sleeve -portion 22 of sumcient length, shape and appearance to resemble the usual candle stem. Integrally formed or moulded with the sleeve portion .or securely fastened thereto is a translucent bowl shaped reflector or shade 23, which extends upwardly sufficiently to surround the filament of the lamp. On the body portion adjacent the shade I provide an annular bead 24, which engages with the outside wall of the socket I'Ia for positioning the stem and preventing transverse relative movement thereof.

As will be seen from Figure l of the drawing, the shade or diifusing bowl surrounds the lower portion of the incandescent lamp, thereby obstructing from View that portion of the incandescent lamp that would otherwise be visible, when viewed from a position under the lamp. The shade will direct and reiiect some of the light rays upwardly to be diffused by the ceiling, while other rays will lter or pass through the translucent shade. Since the large main shade 2| will surround the upper exposed portions of the incandescent lamps, no part of such are clirectly visible and consequently all glaring effects are obviated.

In the manufacture of my invention I prefer to mould my structure by using a plastic compound rnade of a powder or granular mixture consisting generally of a synthetic resin as a binder and a fibrous material as a filler in combination with other ingredients. Such moulded structures are light in weight, durable in structure and possess the quality of unbreakability to a great extent and are well known to the plastic trade under various trade names such as Beetleware, Plaskon, Textolite, and Unyte. Other similar plastic compounds can be used with equally good results. Various pigments to produce different colors or opaqueness can be used with the plastic compound.

It will be understood that though I have suggested the construction of my invention from plastic compounds, having the above characteristics I do not desire that my invention be limited thereto, as other materials may be used.

Manifestly, the construction shown is capable of considerable modification and such modioation as is within the scope of my claim, I consider within the spirit of invention.

What I claim is:

In a lamp structure including a bracket and an upstanding support secured thereto and supporting an incandescent lampi, an opaque elongated body portion surrounding said upstanding support, a semi-spherical shaped bowl having a translucent surface and formed integrally with said body portion and extending therefrom to surround the filament portion of said incandescent lamp, an annular bead positioned intermediate the support and bowl and adapted to secure said body against relative movement with respect to said support.

THEODORE CHANOCK.
