LORIN W. YOUNG, OF NEW YORK, N. Y.

LIGHTING-FIXTURE.

Specication of Letters Patent.

Patented July 15, 1913.

Application led March 8, 1913. Serial No. 753,120.

YTo all 'whom it may concern Be it known thatI, LORIN 'W. YOUNG, a citizen of the United States, residing at New York city, in the county of New York and'State of New York, have invented cer- -tain new and useful Improvements in Lighting-Fixtures, of which the following is a specification.

This invention relates to lighting fixtures, and comprises a unit utilizing the semi-indirect principle, the main features being an upper reflector and a lower bowl ordifusing element, the reflector and bowl being mounted on the lamp support, and thev lamps being located within the bowl, where by the upwardly projected rays are reflected downwardly .and outwardly and the lamps are; substantially concealed by the lower dilfusing bowl, the indirect lighting effect being produced by reflection of light from the surface of the upper reflector, which may convenientlybe made to fit against the ceiling. i

The invention is illustrated in the accompanying drawings in whieh- Figure 1 is a side elevation of the un1t.,

Fig. 2 isa vertical section. Fig. 3 is a vertical section of a modification. v

Referring specifically to the drawings, 6 indicates a hollow exteriorly threaded pipe ronnected to any suitable ceilingbox, and supporting one or more electric lamps 7, the lead wires extending ,through the pipe to the lamps. A bowl'sh'aped reflector 8 is mounted with its rim preferably in contact with the ceiling, and it has a central opening 9. through which the pipe 6 extends;

- This retlector may be of any desired shape or configuration.

`It is supported by a hanger 10, which may comprise a cupped shelltting in lthe opening 9 in the re` Hector, andA having a lower hooked rim l1 which engages under the edge of the reflector around t-he opening 9, the hanger being supported by a nut 12 on the pipe, permitting adjustment to fit the reflector to `proper position. Or instead of a shell, a plate may be used with depending arms hooked under the edge of the reflector. The

Areflector is preferablyymadc of glass, and it may be frosted. i

The lower globe or bowl 13 is made of glass havingl diffusing qualit-ies, and it is .R5 supported by a. focusing device and hanger consisting of a collar 14 screwed on the vscrewedagainst the bottom of pipe 6, and having a number of spacco arms 15 with' screws 16 which engage under the rim 17 of the bowl 13. Obviously any other form of engaging device may be used. It will be noted that the hanger for the bowl can bescrewed up or down on the pipe or stem 6 to adjust the diffusing bowl to proper or desired position.

The shape and ornamentation of the reflector and. the globe may omourse be varied as desired. The upper rays from the lamp/7 are reflected downwinardly' and outwardly from .the reflector above. The bowl conceals the lamp and prevents objectionable brilliancy and acts to diffuse the rays which are no-treflected from above.

In the form shown in Figs. 1 and 2 the bowl is supported by a hanger at its rim. Inthe `form shown in Fig. 3 the bowl 13a is Supported by an ornamental nut 2Q the bowl, and the pipe 6 is surrounded by a sleeve 21 spaced therefrom, and ending in a ball 22 or the like carrying the lamp'sockets 23, the lamps being .inclined upwardly. And in this form the reflector 8 rests on or is supported by a collar 24 on the sleeve 21. A switch` indicated at 25 is inserted in the pipe 6, with a pull chain 26 passing over an arm 27 and through a hole 28 in the reflector and depending in positionfto be pulled for operation of the switch.

In the type shown in Fig. 3 the pull chain from the switch may be conveniently passed downwardly through the pipe 6, allowing the chain to drop from the center. Any appropriate kind of switch may be used for the purpose.

The hollow reflector surrounds and incloses the upper part of the support-ing pipe or stem, and the lower globe surrounds and conceals the lamps and the lower part of the stem, so that the metallic parts of the fixture are not visible from below and therefore may be made of rough or cheap material.

Either of the 'constructions illustrated anddescribed permits the lower bowl to be moved up or down as desired so as to focus the same and obtain different angles of relection from the interior of the bowl, whereby the rays which are reflected. up`

`wardly from the bowl are then reected downwardly and outwardl from the re- 8 and to the angle esired for local conditions. By means of thethreadedpipe,

this Can be done without moving the lamps, thus making a fixture which will be passed 'by underwriters and giving a stationary focusing attachment. 10, shown in Fig. 2, permits the lower hanger 15 to be raised or lowered for the purpose stated.

The hollow hanger If desired, a clear glass cover indicated at 40 may be placed on the bowl 13, to keep out dust.

What I claim as new is: i I

'1. A lighting fixture comprising a depending stem adaptedto support lamps, a

i reflector surrounding and spaced from said stem, for the globe, said hanger projecting upwardly into the recess in said support.

2. A lighting fixture comprising a depending stem adapted to support lamps, a reflector surrounding said stem"aboye the 25 lamps, and having a central openingses -cupped shell tting in said opening and attached at its upper end to the stem and engaging, at its lower-end, the 'edge of the reflector around said opening, to supportthe reflect-or in position, a globe inclosing the.y y lamps, and a hanger for the globe,l mounted on the stem and adjustable thereon within said cupped shell. fr

In testimony whereof, I aiiiX my signa- 3.5 ture rin presence of two witnesses. v
