LIGHTING-FIXTURE.

T 0 all whom it may concern:

Be it known that I, HoLwAY D. FARRAR, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Lighting-Fixtures, of which the following is a specification.

This invention relates to electric lighting fixtures, and has for its object to provide a fixture in which the lighting may be directly (semi-indirectly) and indirectly reflected and diffused, in order that the ad vantages of all systems of lighting may be combined into the one unitary fixture.

Another object of the invention resides in a fixture of the above character wherein is embodied a pair of oppositely arranged reflectors which are so disposed with regard to the sources of light that the entire area of one side of each of the reflectors may be used for diffusing light rays, and to provide means integrallyseparate from the reflectors for mounting the sources of light, the construction being such that the reflectors are not reduced in reflecting area by the mountings of the light sources.

With these and other objects in view, as will appear as the description proceeds, the invention accordingly consists in the novel features of construction, combinations of elements and arrangement of parts, hereinafter to be fully described and to have the scope thereof pointed out in the appended claims.

In the accompanying drawing, forming a part of this specification, and in which similar characters of reference denote like and corresponding parts:

Figure 1 is a top plan view of the lighting fixture comprising the present invention, parts thereof being broken away to disclose the underlying structure, and,

Fig. 2. is a vertical sectional view taken through the fixture.

In the vpreferred form of the invention.

the lighting. fixture 1 consists of an annulus 1 which, as shown, may be composed of a monolythic substance and suitably molded to present exterior, designs of attractive configuration. Located within the inner and upper part of the annulus is a metallic ring 2 which is positioned to lie within a recess 3 formed in the inner wall 4: of the annulus. Secured to either the ring or the annulus 'is a plurality of hooks '5, with Y which are connected the lower ends of up- Specification of Letters Patent.

wardly extending chains 6, the latter being employed in the usual manner for effecting the suspension of the fixture from a suitable support. This form of support or suspenslon is merely disclosed for purposes of illustration, as it'is obvious that many other convenient constructions may be employed wlth equal facility for accomplishing the retention of the fixture in an operative position.

To secure the hooks 5 in position, the annulus 1 may be provided with a plurality of embedded nuts 7, which are arranged to receive threaded ends of a plurality of retaining screws '8, the latter being employed to pass through receiving openings thereof provided in the base portions of the hooks 5 and to thereby securely connect the hooks in an applied position upon the annulus. Inserted between said hooks and the ring 2 and clamped in position by the screws 8 are a plurality of metallic retaining fingers 9, the latter being disposed to project downwardly and inwardly into the interior of the annulus 1, and have their lower ends bent as at 10 to provide a base for the reception of the outer peripheral edge of an upper reflector 11. This reflector is arrangedhorizontally within the annulus and is provided with a concaved reflecting surface 12', which is so disposed as to cast light rays direct thereon in a substantially upward direction and hence iscapable of carrying out theindirect lighting features of the fixture. Further, the screws 8 also rigidly carry laterally extending arms 13, to the outer ends of which are suitably con nected a plurality of electric light sockets 14, in which bulbs 15 are adapted to be carried. By this construction, it will be manifest that the bulbs 15 will project horizontally above the reflecting surface 12 of the reflector 11 so that the light rays emitted from the bulbs will be reflected and projected in an upward direction.

'From the construction described, it will be manifest that the screws 8 will serve to securely mount the upper structure of the fixture in connection with the annulus l and at the same time servetorender the structure conveniently accessible and capable of being readily dismantled, if necessary. Any suitable system of wiring may, of course, be employed to transmit current to the bulbs 15. By threading the screws 8 into their applied positions within the nuts 7, it will be seen that the same will act to bind the fingers 9, the hooks 5 and the arms 13 in securely clamped manner, thus permitting of the suspension of the fixture as well as providing a rigid mounting for the light and reflector mechanism.

The lower inner portion of the annulus 1 is provided with a ring 16 which extends around the lower portion of the wall 4. This ring is retained in position through the agency of a plurality of screws 17 which are threaded into permanently held nuts 18 embedded in the annulus in amanner similar to the nuts 7. By the provision of the screws 17, it will be apparent that the ring 16 will be securely retained in its applied position and that undue slipping thereof will be prevented. The upper edge of the ring 16 is employed to provide a support for the outer circumferential edge of a lower reflector 19. This reflector is located in op position to the reflector 11 and accordingly its reflecting surface 20 is of concave formation, the construction of the reflector 19 being such that the same will tend to cause light rays direct thereon in a downward direction, and will thereby serve to provide for the direct lighting features of the fixture. The screws 17 are provided with lateral arms 21, which support at their outer ends a plurality of light sockets 22, in which incandescent lamps 23 are adapted to be mounted. These lamps extend substantially horizontally and are arranged in contiguous relationship with the reflecting surface 20 of the reflector 19. By this construction the lights 2-3 will be positioned beneath the reflector 19 in such manner as to make use of the entire area of the reflector 19 as a reflecting surface. In other words, the lamps l5 and 23 are mounted so as to be relatively independent of the reflectors whereby the entire area of the reflectors may be utilized for light diffusing purposes. If desired, a

glass bowl 2% may be employed for concealing the lamps 23 and to soften the light diffusion of the reflector 19. Thisbowl is preferably formed from a translucent material and may be secured to the annulus 1 in any suitable manner. In this instance, the rim of the bowl is provided with a circumferential enlargement 25 which is adapted to form an annular shoulder 26. The ring 16 is provided with a plurality of set screws 27, which may be so threaded that their ends will project beneath the enlargement 25 so as to provide a seat for the reception of the shoulder 26. This construction provides simple yet effective means for removably retaining the bowl 2 1 in its applied position.

From the foregoing description, taken in conjunction with the accompanying drawing, it will be apparent that the present invention provides a lighting fixture wherein is embodied mechanism for providing for direct (semi-indirect) and indirect lighting, whereby the advantages of all systems are :to be obtained and their disad vantages mitigatedf One essential feature of the invention resides in the manner of mounting the incandescent lamps with respect to the reflectors. As has been previously pointed out, this mounting is such as to enable the entire reflecting areas of the reflectors to be utilized for light diffusing purposes and materially facilitates the construction of the fixture. In prior devices of this character, it has been customary to provide the reflectors with axial openings through which the lamps havebeen disposed to extend. In the present construction, it will be noted that the reflectors 11 and 19 are unbroken throughout their inner area in order that the added advantages of light diffusion and accessibility in mountingmay be obtained.

What is claimed is:

1. An interior lighting fixture comprising, in combination, a retaining annulus, a reflector structure positioned within said annulus and formed to include a pair of opposed concave reflecting surfaces which ex tend substantially across the: full internal diameter of said annulus, and a plurality of incandescent lamps arranged to be carried by said annulus so as to project and to cast light exteriorly of the fixture both above and below said reflecting surfaces 2. An interior lightingfixture comprising, in combination, a retaining annulus, a reflector structure positioned within said annulus, said structure being' formed to include a pair of opposed, reflecting surfaces of concave formation, which surfaces extend substantially across the full internal diameter of said annulus, and incandescent lamps carried by said annulus and situated on substantially horizontal planes both above and below said reflecting surfaces and to cast light in both directions from said fixture, whereby said fixture will be capable of effecting both direct and indirect illumination.

3. An interiorlighting fixture comprising a retaining annulus, a reflector structure positioned within said annulus and formed to include a pair of oppositely arranged reflecting surfaces, which extend substantially across the full internal diameter of said annulus, and a plurality of horizontally disposed lamps stationarily supported on horizontal planes both above and below saidreflecting surfaces, whereby the latter will serve to cast light in opposite directions exteriorly from said fixture.

4:. An interior lighting fixture'comprising a retaining annulus, an imperforate reflector structure carried by said annulus, said reflector structure being formed to include a pair of opposed reflecting surfaces situated to extend completely across the internal diameter of said annulus, and stationarily supported horizontally arranged lamps positioned both above and below said reflecting surfaces, whereby the latter will cast light in opposite directions exteriorly of said fixture.

5. In an interior lighting fixture, a retaining member, an imperforate reflector struc ture carried by said member, said reflector structure being formed to include a pair of oppositely arranged concaved reflecting sur- "faces so disposed as to extend substantially across the full internal diameter of said member, and incandescent lamps carried by mountings projecting from said annulus and arranged both above and below said reflecting surfaces, so that the latter will be capable of casting light in opposite directions exteriorly from said fixture.

In testimony whereof I afiix my si nature.
