ELECTRIC-LIGHT FIXTURE.

To all whom it may concern:

Be it known that I, RICHARD S. GIESE, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented anew and useful Electric-Light Fixture, of whlch the following is a specification. I

This invention has reference to electric light fixtures and its object is to provlde a combination semi-indirect and shower fixture in which metallic parts are reduced to a minimum. I

In accordance with the present invention there is provided a dish or bowl of the general character employed in semi-indirect lighting but modified in structure to adapt it to the purposes of the present invention, and such bowl is utilized as a spreader for the shower lights while the shower devices are employed as the supporting means for the dish or bowl.

employed to sustain the dish or bowl of the semi-indirect side of the fixture are avoided, and the only metallic parts employed are the customary sockets for the lighting bulbs of the shower, chains carrying the bulbs, and

the customary shade-holders supporting' shades such as are. used in connection with single lamp bulbs, such shades forming the sole support for the dish or bowl.

The invention will be best understood from a consideration of .the following detailed description, taken in connection with the accompanying drawings forming part of this specification, with the further understanding that while the drawings show a practical form of the invention, the latter is not confined to any strict conformity with I the showing of the drawings, but may be shown ordinary electric lamp sockets 1 de- In this manner all me-- tallic rings or other supports customarily Specification of Letters Patent.

having shade-engaging set screws 4.

In shower lights it is customary to employ elongated shades quite closely surrounding the lamp bulbs, andsuch shades are indicated 1n the drawing at 5. Each shade is provided with a neck 6, which where joining the body of the shade forms a shoulder 7. Each socket 1 is provided with a suspension ring 8 which may be of standard or special constructionand arranged for the passage of the usual conductor 9 and the reception of a suspension chain 10 of the character ordinarily employed 1n electric light fixtures.

'The chains 10 in the installed fixtures are carried to a ceiling canopy and there secured in the customary manner, but as this is the common practice in the installation of shower and other lighting fixtures, it is not deemed necessary to show it.

Shower electric lighting fixtures are often provided with a spreader for the shower lights in the form of a plate or dish of ornamental configuration, which dish is suspended by chains, such as the chains 10, while sockets, such as sockets 1, are installed in the dish or plate to receive the bulb, such sockets belng sometimes suspended from the dish or plate by short chains.

By the present invention there is provided a dish or bowl 11 of glass or other suitable material usually of a translucent nature, that is, the glass or other material is of a character to transmit light difl'usively while the inner wall of the dish is made reflecting for the purpose of directing light against the ceiling of the room or compartment in which the fixture is installed. This is the usual practice in semi-indirect lighting, and with the fixture of the present invention there is provided a lamp socket 12 designed to carry an electric light bulb 13, the socket being suspended by a customary conductor cord 14 depending from the usual canopy supporting the fixture, but which canopy is not shown in the drawings.

The dish or bowl 11 has its rounded or generally convex face directed downwardly,

so that the hollow interior of the dish is toward the ceiling and at the elevation at which the fixture is usually placed the bowl I 20 for the dish 11 completely hides the lamp bulb 13 from observation. The dish 11 has upstanding sides 15 usually provided at the upper edge with a flange 16 serving as an ornamental finish.

The central portion of the dish has a drop i necks 6 of the shades 5 through them with the portions of the dish immediately surrounding the passages 16 resting on the shoulders 7. These shades, therefore, serve as supports and consitute the sole supports At the same time the disposition of the passages 19 is such that the dish 11 serves as a spreader for the direct lighting elements of the shower. The result is that the sole supporting means for the en- I tire fixture consists of the chains 10 each of which carries a socket 1 individual thereto, and these chains are the only metallic parts needed for the suspension of the entire fixture from the usual ceiling canopy, (not i shown).

The bulge 17, which extends downwardly in the installed position of the fixture, is designed to partly house the lamp bulb 13, so that the source of indirect lighting represented by the bulb 13 is partly within the bulge 17, thus increasing the light transmitted through the dish toward the floor of the compartment to be illuminated, while reflections from the inner surface of the dish toward the ceiling cause the lighting up of 00 ture may be used either as a direct fixture or as a semi-indirect fixture, or the two styles of lighting may be employed at one time.

By the present invention the benefits of both direct and semi-indirect lighting are r obtained with a minimum of metal in the fixture, and with the elimination of more or less unsightly and shadow-casting parts.

The fixture also has the advantage of economical construction, for certain parts i such as the sockets 1, heretofore employed in such fixtures solely to carry the direct light 7 ing members, are utilized in the present fixture as, the supporting means for the indirect lighting side of the fixture, that is, the

' 6 dish 11.

The shower lights are shown in the drawings as three in number, but it will be understood that any suitable number of such lights may be employed, and usually such lights are distributed evenly about the fixture.

lVhat is claimed is 1. An electric light fixture provided with shower lights each having supporting means individual thereto, and a semi-indirect lighting dish or bowl carried directly and solely 7 by the shower lights.

2. An electric light fixture comprising a plurality of electric lamp sockets and suspension devices therefor, shades for the sockets, and a semi-indirect lighting dish having passages therethrough for the shades and resting 011 and supported solely by said shades.

3. An electric light fixture comprising a plurality of electric lamp sockets, shades and shade holders therefor, suspension means connected to the sockets, and a semi-indirect lighting dish having passages therethrough for the necks of the shades and resting upon and supported by the shades, said dish serving as a spreader'for the sockets and shades to constitute-the fixture a combined shower and semi-indirect fixture.

4. An electric light fixture provided with a plurality of electric lamp sockets, shades and shade holders therefor, suspension means connected to the sockets, and a semiindirect lighting dish having upstanding sides, a central hollow depression, and substantially flat portions between the central depression and the sides, said fiat portion having passages therethrough distributed about it for the necks of the shades, the dish resting upon and being supported by the shades, whereby the fixture constitutes a combined shower and semi-indirect lighting fixture. V

5. In an electric light fixture of the com- 'bined shower and semi-indirect type, a semi- ;1I1d1160l3 lightlng dlsh having upstandlng marginal portions, a central hollow depression, and a substantially fiat portion surrounding the hollow depression and merging into the upstanding sides, the fiat portion having passages therethrough distributed circumferentially about the central depression.

6. A combined shower and semi-indirect electric light fixture, comprising a semi-indirect dish or bowl, and shower lights extending through and below the bowl and provided with supporting means, the shower lights constituting the sole support for the dish. 7 a

7 An electric light fixture provided with shower lights each having suspension means connected and individual thereto and con stituting the sole suspension means for the entire fixture, and aspreader for theshower lights and the suspension means, comprising a semi-indirect lighting dish or bowl directly engaging and carried solely by the shower lights.

8. A combined direct and semi-indirect lighting fixture provided with separate direct lighting means, a separate suspension means for each direct lighting means a spreader for the separate direct lighting means, comprising a semi-indirect lighting dish or bowl directly engaging the direct lighting means, and means for supporting light producing means in operative relation to the dish or bowl to direct light through the bowl and for the reflection of light from 15 the bowl to produce indirect lighting effects;

9. A combined direct and semi-indirect lighting fixture comprising a semi-indirect dish or bowl, and a series of separate shower lights extending through and below the bowl within the margins thereof and each provided with a suspension means individual thereto, the bowl constituting a spreader for the suspension means and said suspension means constituting the supporting means for the fixture.

In testimony, that I claim the foregoing as my own, I have hereto ailixed my signature in the presence of two witnesses.
