LIGHTING FIXTURE Filed Deo. 17, 1927 A'I TORNEY Patented Oct. l, 1929 UNITED STATES PATENT ori-Tee JACOB SCHAFFER, OF NEW YORK, N. Y., ASSTGNOR TO STAR CHANDELIER C0., INC., A CORPORATION' OF NEW' YORK LIGHTING- FIXTURE Application filed December' 17, 1927.

The present invention relates to lighting fixtures and is more particularly directed toward a lighting fixture suitable for use as a dining room dome.

Fixtures of this type are generally intended for use in dining rooms over the table. They are intended to give a strong illumination on the table and are provided with shades generally made of silk to screen the direct i0 rays of the lamps from those seated at the table. It has formerly been the practice in supporting domes of this character to employ1 a metal ring or band about the upper part of the shade and to support it by arms carried from the central body of the fixture. The fixture is otherwise open above the 'shade and is without ornamental parts other than the supporting arms.

The present invention contemplates a lighting fixture dome especially designed for use in dining rooms and the like, wherein the shade is supported from a ring which is surmounted by an upwardly and inwardly directed grille, and wherein this grille is so ar- 25 ranged that the inside of the grille may be illuminated by direct and reflected rays from the light sources, sufficient light being allowed to escape upwardly through the grille to illuminate the `ceiling and upper parts of the room without casting objectionable shadows.

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 of the present invention rather than limiting the same. l

In these drawings:

Figure 1 is an elevational view of a lighting xture embodying the present invention; and Figure 2 is an enlarged elevational view with parts in section showing interior construction and the path of the light rays.

As illustrated in Figure 1, the supporting parts of the lighting fixture include the conventional canopy 10, suspending chain 11, loop 12 and spindle 13. These parts may be of any approved form, style or design and may be varied as desired.

The loop 12 is threaded onto the upper end understood that the drawings are illustrative of a pipe1et.

SeriaI No. 240,770.

This pipe extends down through fixture parte Tn the form of con struction illustrated in Figure 2, the lower end 15 of the pipe 14 is threaded to a bushing 16. This bushing supports a stamping 17 carrying a cross member or strap 1S. This cross member carries a nipple 19 and a knob 2() is threaded onto the lower end of the nipple. This knob supports a stamping 21 which carries the lamp sockets 22 and fits inside the skirt 23 of the st-amping 17 so as to provide a closed splicing chamber for the wiring of the fixture. down through the chamber.

These wires may be passed pipe 14 to the splicing The upper end of the stamping 17 has a shoulder 23 upon which rests a sleeve 24- which may be made of ornamental material such as spiral tubing. A casting 25 is snpported at the upper end of this sleeve 24 and between the sleeve and lower spindle 13.

1 L The upper edge oi the shade may be concealed by a depending rim 31 carried by the casting 25.

The casting 25 may take various forms and conligurations and may be ornamented in a wide variety of manners. One suitable ornamental design for this member is shown in Boehringer application for design patent Serial Number 24.361, filed December, 1927. This casting consists essentially of a grille indicated generally at 32 which is placed between the upper band 27.

tively open,

central portions 25 and the This grille is preferably comparaand is provided with comparatively large apertures somewhat as indicated in the drawing.

When the fixture made up as has been described, is lighted, most of the light is di rected downwardly underneath the shade, as is customary in fixtures of this type. A portion of the upwardly directed light reaches the inner surface of the grille and is reflected inside this grille somewhat as indicated by the ray marked A. This ray of light strikes the inner surface of the grille, which is preferably polished and plated. These rays of light are reflected onto the other parts of the interior of the grille and out through the openings of the grille so that the light is scattered about the inside of the grille and the same is illuminated from the lamps. In this manner the interior of the grille appears bright instead of being shadowed. The upwardly directed light goes out through the holes in the grille somewhat as indicated by the rays marked B and C. This light illuminates the ceiling, spindle and upper parts of the room so that the same are not dark. Owing` to the fact that a number of lamps are used in the fixture, the light will be coming from a number of sources and the rays coming through the various holes in the grille will overlap so that no objectionable shadows are produced on the ceiling.

From the foregoing, it will be apparent that the present Xture is one which may be easily assembled out of readily made parts.

y The majority of the lightmay be directed downwardly onto the table and at the same time a substantial amount of light is permitted to reach the upper parts of the rim for purposes of general illumination. The light reflected from the interior of the grille will also produce a pleasing effect when the fixture is viewed from a slight distance to one side ofthe same.

It is obvious that the invention may be embodied in many form-sl and constructions within the scope ofthe claim, and I wish it to be understood that the particular form shown is but one of the many forms. Various modifications and changes being possible3 I do not otherwise limit myself in any way with respect thereto.

That is claimed is:

A lighting fixture comprising a central supporting tubular stem carrying a plurality of lamp sockets and lamps arranged in a cluster at its lower end, a downwardly and outwardly flaring grille supported from the stem, the upper inner portion of the grille being spaced a substantial distance above the lamp, and a shade carried from the lower large diameter portion of the grille in a position to screen the light in a horizontal direc tion, the grille having comparatively large apertures to permit light to escape upwardly from the lamps to illuminate the ceiling, the

inside of the grille scattering the light falling upon it so that the parts visible through the apertures therein appear illuminated.
