ATTORN EY Patented Feb. 1, 1938 PATENT OFFIQE LIGHTING FIXTURE Leroy C. Doane, Meriden, Conn, assignor to The Miller Company, Meriden, Conn, a corporation of Connecticut Application September 25, 1936, Serial No. 102,525

4 Claims.

The present invention relates to lighting fixtures and is more particularly directed toward lighting fixtures of a type suitable for use in the illumination of dining rooms.

The present invention contemplates a lighting fixture adapted for indirect lighting and to obtain an intense direct lighting beam directing below the fixture.

Referring to the present invention, the fixture employs a single light source, preferably in the form of an upwardly extending incandescent lamp bulb, and this source is surrounded by an annular, highly-reflecting, open-topped shade or bowl, having a transparent bottom portion through which direct light passes down to the table. The fixture is preferably provided with a downwardly removable socket cover, which supports the glass shade and has switch-controlling mechanism in the form of a knob at the bottom of the fixture.

Other and further objects of the invention will appear as the description proceeds.

The accompanying drawing shows, for purposes of illustrating the present invention, it being understood that the drawing is illustrative of the invention, rather than limiting the same.

In this drawing:

Fig. 1 is a diagrammatic elevational view illustrating a fixture above a dining room table.

Fig. 2 is a side elevational view with parts in section; and

Fig. 3 is an inverted plan View.

In the construction shown in the drawing the fixture is suspended by means of a loop In which carries two downwardly extending tubular arms H and i2, one of which carries the wires indicated at Ha. The lower ends 13 of these arms are secured to the upper outwardly bent ends M of a U-shaped strap l5. This strap has inwardly extending lugs i6 which support an upwardly opening lamp socket l'l, adapted to carry an incandescent lamp,as indicated at IS. The U-shaped strap l5 also carries a switch, indicated at 19, having an operating knob indicated at 20.

The switch is held in place by locking rings 2! and 22.

The locking ring 22 for the knob 20 is externally threaded to receive a knurled ring 23, by means of which a socket cover 24 is held in place.

This socket cover supports a glass shade 25, the

shade being held between the top of the socket cover and the ends it of the U-shaped strap. The shade 25 extends somewhat above the top of the lamp bulb, as indicated, and the side walls are preferably concave to the incident light and converge slightly downward.

These side walls are preferably provided with an external enamel coating, indicated at 26, for the purpose of increasing the amount of light reflected by the bowl or shade. A slight amount of light is transmitted, as indicated in the drawing. The bottom 27 of the shade is clear crystal glass and is preferably slightly ribbed, as indicated at 28, Fig. 3. This bottom portion is upwardly and inwardly tapered so as to reduce the area of the glass in the normal line of vision, thereby reducing any brightness caused by surface reflections. If desired a reflector 30 may be carried inside the glass shade, this reflector acting to intercept a portion of the light and reflect it downwardly, as indicated by the ray 3|. The fixture is preferably provided with an annular conical shade 32 of suitable ornamental appearance and preferably provided with a highly reflecting inner-surface.

Fixtures such as herein described are capable of inexpensive manufacture and may be completely assembled and wired, except for the glass, at the factory. The glass and external parts of the fixture may be ornamental in various Ways to obtain the desired appearance.

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 merely, the invention comprehending all variations thereof.

What is claimed is:

1. A lighting fixture comprising a light source, and an annular, open-topped glass shade having highly reflecting side walls, slightly convergent downwardly and adapt-ed to produce a wide upward distribution of direct and reflected light for indirect lighting, and a lower, clear glass zone integral with said walls for downwardly transmitting light within a narrow angle from nadir for direct illumination of a circular area underneath the fixture, the clear glass zone being fluted and tapering upwardly and inwardly.

2. A lighting fixture comprising a light source, and an annular, open-topped glass shade having highly reflecting side walls, slightly convergent downwardly and adapted to produce a wide upward distribution of direct and reflected light for indirect lighting, and a lower, clear glass zone integral with said walls for downwardly transmitting light within a narrow angle from nadir for direct illumination of a circular area underneath the fixture, and a downwardly acting conical reflector extending down to the bottom of the side walls and disposed between the side walls and bottom zone for directing light through said zone.

3. A lighting fixture comprising a suspension, an upwardly opening lamp socket carried at the bottom of the suspension, a lamp bulb in the socket, a switch carried below the socket, a downwardly removable socket cover about the socket and switch, and an annular open-topped shade about the lamp bulb, the bottom of the shade being transparent for downwardly transmitting light within a, narrow angle from nadir for direct illumination of a circular area underneath the fixture, the side walls of the shade being highly reflecting and slightly divergent upwardly.

4. A lighting fixture comprising a bifurcated support, a U-shaped member connecting the lower ends of the support, an upwardly-opening lamp socket carried in the U-shaped member, a switch carried by'said member, a switch operating knob extending downwardly, a downwardly removable socket cover secured about the U-shaped member, and an annular open-topped shade about the lamp bulb, the bottom of the shade being transparent for downwardly transmitting light within a narrow angle from nadir for direct illumination of a circular area underneath the fixture, the side walls of the shade being highly reflecting and slightly divergent upwardly.
