The present invention relates to lamps and is more particularly directed toward a prtable lamp such as a table lamp provided with an illuminated column. p r

The present invention contemplates the provision of a table lamp having main light sources such as a cluster of lamps inside the shade. This lamp cluster is supported above a standard which carries a column or cyl- .inder of light transmitting material. Provih sion is made for illuminating the upper end of this cylinder so that it glows with a. dim light.

The present invention contemplates that this lighted column may be available independent of the lighting of the main lamps and that the intensity of the light coming out of the column can be regulated. It also contemplates that the same lamp which is gflemployed for lighting the column may by variation of a small'shade or reflector, be employed to provide a dim light inside the main shade when the main or large lamps are extinguished. I V

The accompanying drawings show, for purposes of illustrating the present invention one of the many possible embodiments in which the invention may take form, it being understood that the drawings are illus- 3otrative ofthe invention rather than limiting the same.

In these drawings: Figure 1 is a side'elevati table lampwith parts in section; 35. Figure 2 is a horizontal sectional view of the standard or column taken on the line 2,2 of Figure 1;

Figure 3 is an enlarged fragmentary vertif cal sectional view; and V Figure 4; 1s a wiring dlagram. As shown in the present drawing's, the 1nventlon 1s employed in a table lamp It has a base indicated at 10 andfla metal column or I standard indicated at 11. This column or standard is as here shown provided with three vertical supporting parts or straps 12 of suitable ornamental configuration. Near the lower end of these straps, the standard may if desired, be provided with the grill 13. 5Q The column or standard is made openinside onal view of a a the 'l'usterf.'2O.

the socket. The return :from the socket is connected onto the lead 33. The circuit for the major lamps may be turned off and on byfthe switch in the ordinary manner, while the small lamp 36 in the small socket is controlled by the pull chain independently of the control of the other two lamps. It will, of course, be understood that this is merely one switching arrangement which may be used. One can use a conventional three position switch to separately control the lamps.

The socket 24 and associated parts are carried inside the frame members 19a, 19b and 190. The light emitted from the small central lamp 36 passes downwardly through the hole 18 in the stamping 15 and into the upper end ofthe light transmitting column 14. This causes the exposed surfaces of the column to glow at low intensity so that it is visible between the metal columns or straps 12 and through the grill 13. When one desires to obtain general illumination from the lamp 36, the shield 26 may be moved up to the dotted line position as indicated in Figure 1. The plate 15 cuts ofl direct light from the lamp 36 and assists in bringing the supporting straps 12 and grill 13 into relief when the light is concentrated onto the column 14. It is obvious that the invention may be" embodied in many forms and constructions Within the scope of the claims, and I wish it to be understood that the particular form shown is but one of the many forms. Various modifications and changes being possible, I do not otherwise limit myself in any way with respect thereto.

What is claimed is:

1. In a lamp, a standard comprising metal supporting parts and an interposed column of translucent material, the supporting parts being separated to expose the sides of the column, a lamp bulb carried adjacent the end of the column and adapted to cast direct light on the end of the column which retransmits and diffuses the light so that the exposed surface of the column glows, an opaque shield carried at the upper end of the standard, the shield being apertured to permit light to reach the column and acting to cut off extraneous light whereby the supporting parts receive no direct light from the lamp bulb, a small adjustably supported reflector about the lamp bulb, and a large shade outside the reflector and shield, the reflector acting to concentrate the light onto the end of the column or to allow it to fall on the shield which scatters it inside the shade.

2. A portable lamp having a base, a supporting standard provided with a column of light transmitting material, main and auxiliary lamps, a reflector about the auxiliary lamp, means for separately controlling the lamps, and a shade about the main lamps, the auxiliary lamp being disposed directly above the end of the column whereby the column glows when the auxiliary lamp is lighted and the main lamps are extinguished, the reflector being adjustable to provide for dim general illumination as well as illumina-
