LIGHTING FIXTURE Filed July 29', 1952 INVENTOR WITNESSES Spencer-7 Tuckerfi ATTORNEYS Patented Oct 24, 1933 UNITED STATES LIGHTING FIXTURE Spencer John Tucker, Jamaica, N. Y., assignor to Edwd. F. Caldwell & Co. Inc., New York, N. Y., a corporation of New York Application July 29, 1932. Serial No. 626,072

1 Claim.

An object of the invention is to provide a lighting fixture having direct lighting means and also indirect lighting means, the lighting fixture being provided with a lamp disposed relatively to the direct and indirect lighting means to secure maximum direct and indirect lighting.

Another object of the invention is to provide an opaque reflecting bowl with a translucent member extending at an outward and upward angle from the rim of the bowl, an electric lamp with a filament being disposed within and spaced from the bowl and the translucent member with the filament approximately on the level of the junction of the bowl and the translucent member to obtain the maximum direct and indirect lighting results.

Other objects of the invention are to provide convenient means for mounting the translucent member on the bowl and to dispose the translucent member with its outer rim positioned on a straight line extending from the central portion of the filament at approximately fifteen degrees from the horizontal.

Additional objects of the invention will appear in the following specification in which the preferred form of the invention is described.

In the drawing, similar reference characters refer to similar parts in all views, of which Figure l is a side sectional elevation of the invention,

Figure 2 is a plan view of Figure 1, and

Figure 3 is a fragmentary view in section illustrating a modification.

By referring to the drawing it will be seen that a tubular lamp socket cover 5 is provided which is supported by tubular or other member 6, chains or flexible members 7 extending from the lamp socket cover 5, the chains or flexible members '7 being secured to eyes 8 on the inner surface of an opaque bowl 9, the inner surfaceof which acts as a reflector. Disposed at the sides of the bowl 9 there is an annular bead 10 which is spaced below the upper rim 11 of the bowl 9 to form a support for the inner rim 12 of an inverted frusto-conical annular translucent member 13 capable of diffusing and also reflecting light rays.

A lamp 14 having the usual socket is secured in the lamp socket cover 5, the lamp 14 having a filament 15 which is disposed on the level of the junction between the upper rim 11 of the opaque bowl 9 and the inner rim 12 of the translucent member 13, the globe of the lamp 14 above the filament being frosted at 16 to difiuse the light rays.

As will best be seen by referring to Figure 1, the translucent member 13 is of such shape as to extend outwardly and upwardly from the rim 11 of the bowl 9, the outer rim 17 of the translucent member being positioned so that a line from the central portion of the filament 15 to the outer rim 17 of the translucent member 13 will be disposed at an angle of approximately fifteen degrees from the horizontal.

With the lighting fixture constructed and the parts disposed in the manner set forth, the light rays from the lamp 14 will be reflected upwardly by the inner reflecting surface of the opaque bowl 9, while the light rays will also be diffused by the frosted surface 16 of the lamb globe. Therefore, the light rays will not only be directed against the translucent member 13, but they will also be directed upwardly against the ceiling for indirect lighting, the angularity of the translucent member 13 with reference to the filament 15 being provided to obtain the maximum direct and indirect lighting results.

In the modification illustrated in Figure 3 of the drawing I illustrate wires 18 as supports for the globe in place of the chains 7 of the form illustrated in Figures 1 and 2 of the drawing. These wires 18 have buttons or enlargements 19 at one end and are provided with hooks 20 at their other ends. The lamp socket cover 5 is provided with openings 21 through which the wires 18 are projected, the buttons 19 serving to close the openings and also limit the movement of the wires, and the hooked ends 20 of the wires are engaged in eyes 22 on the bowl. These wires 18 give a more rigid connection between the cover 5 and the bowl than is accomplished by the chains but it is of course understood that I do not limit myself to any particular or specific means for coupling the parts together.

What is claimed is:

In a lighting fixture, an opaque bowl having aninner reflecting surface and an upper rim with a bead around the bowl below the said rim, a tubular member, means connected with the tubular member and the bowl for supporting the bowl below the tubular member, a lamp supported by said tubular member, the lamp being provided with a filament disposed approximately on a level with the upper rim of the bowl, an inverted frusto-conical annular translucent member in which the upper rim of the bowl is disposed, the inner edge of the translucent member resting on the bead, to thus support said translucent member.
