ATTORNEY Patented June 18, 1940 PATENT OFFlCE PORTABLE LAIWP James Gould, Jr., Meriden, Conn., assignor to The Miller Company, Meriden, Gonn., a corporation of Connecticut Application September 6, 1939, Serial No. 293,530

4 Claims.

The present invention relates to portable lamps, and is more particularly directed toward portable floor lamps having auxiliary lighting means to render the shade of the lamp luminous.

5 The present invention contemplates introducing into the usual column of a semi-indirect floor lamp a short distance below the shade means for directing a light of low intensity toward the shade from underneath. In carrying the present inven- 10 tion into practice it has been found convenient to provide the lamp standard or column with a harp which carries a secondary lamp socket and lamp bulb and to surround the same with an opaque enclosure having a diffusing cover 15 through which the light rays can pass and fall on the inside of the shade.

The accompanying drawing shows, for purposes of, illustrating the present invention, an embodiment in which the invention may take 20 form, it being understood that the drawing is illustrative of the invention rather than limiting the same.

In this drawing:

Figure l is a perspective view of the upper part 25 of a floor lamp; and

Figure 2 is a vertical sectional view at an en-,

larged scale.

The lamp standard employs a pipe l and an outer ornamental tubing H as usual. A com- 30 bined hickey and harp i2 is threaded on to the top of the pipe l0 and against the tubing II. This combined hickey and harp supports a small switch controlled lamp socket I3 adapted to carry a lamp bulb l4 and has two arms l5 and Hi to 35 accommodate the socket and lamp bulb. These arms come together at the top as indicated to form a boss ll which is threaded as indicated at I8 to receive a coupling I9 for the head 20 of the lamp. This head supports the usual diffusing 0 bowl 2|, bulb 22 and shade 23.

A diffuser 24 which may be of glass or suitable plastic is supported on the boss I? and is adapted to fit against the upper end of a funnel shaped closing member 25. This enclosure may be made 45 of sheet metal and is supported on a collar 26 threaded on the outside of the combined hickey and harp I2.

When the lamp M is lighted and the main lamp 22 extinguished the light rays fall on the 50 inside of the shade 23 rendering it dimly luminous. When the main lamp 22 is lighted the structure forming the supplemental light source may be lighted or not. In either case it adds an ornamental touch to the column of the lamp 55 and its function as a supplemental lighting unit is not apparent to the casual observer.

It is apparent that, within the scope of the invention, modifications and different arrangements may be made other than is herein disclosed, and the present disclosure is illustrative 5 merely, the invention comprehending all variations thereof.

What is claimed is:

1. A lamp having a lamp head comprising a body, a primary light source carried thereby and a downwardly and outwardly flaring shade about the primary light source, a coupling extending downwardly from the body, a curved arm secured to the lower end of the coupling and having its lower end directly under the coupling but spaced therefrom, a secondary lamp socket and lamp bulb supported by the lower end of the arm and disposed between the ends of the arm, a substantially horizontal light diffusing cover of substantial area above the secondary lamp bulb and non-removably secured between the top of the arm and the bottom of the lamp head, a vertically movable, opaque housing normally disposed about the secondary socket and lower part of the arm and extending downwardly from the periphery of. the cover so as to conceal the arm, secondary lamp socket and bulb, and means for detachably securing the housing at its lower end in such position or for permitting lowering it to give access to the secondary lamp bulb. 30

2. In a portable lamp, in combination, a tubular standard, an apertured hickey near the top thereof so that wires may be passed outwardly through the aperture, an upwardly extending arm having its intermediate portion offset from the standard axis and its upper end in the axis,

a lamp head secured to the upper end of the arm and including a primary light source and a reflector, a shade about the reflector, a secondary lamp socket and lamp bulb secured to the hickey and disposed between the ends of the arm, and

an enclosure for the secondary source including a substantially horizontal, centrally apertured, diffusing cover, means at the upper end of the arm for fixedly supporting the diffusing cover, the diffusing cover being of substantial area to transmit light upwardly under the shade for lighting the shade, a vertically movable, opaque housing normally disposed about the secondary 5o socketand lower part of the arm and extending downwardly fro-m the periphery of the cover so as to conceal the arm, secondary lamp socket and bulb, and means for detachably securing the housing at its lower end in such position or for a secondary lamp socket and lamp bulb secured inside the harp, a centrally apertured light transmitting cover supported at the top of the harp, an opaque housing extending from below the hickey aperture up to the edge of, the diffusing cover, a housing supporting ring threaded onto said member, a coupling secured to the top of the harp and extending through the difiusing cover, and a lamp head having a primary light source,

the lamp head being carried by the coupling and 10 securing the difiusing cover in place.
