Application and April s, 191s. semina. sana Y To all whom itmay concern:

Be itl known that I, EUGENE J MEYBERG, a ycitizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California,

useful Improvements in Lighting-Fixtures, Vof which the following' is a specification.

This invention relates to a li hting fixture, and pertains especially to xtures for semi-indirect lighting It is an object of this invention to provide a fixture having a reflector so constructed and disposed with relation to a source of light that a portion of the light rays 'may ass through said reflector and be refiected rom a surface below which the fixture is disposed. Y

It is another object of this invention to provide a fixture easily assembled and disassembled.

It is a further object to provide a fixture having a removable transparent reflector.

In addition to the broader features of design of a fixture, the invention includes certain ecific features of construction by which important advantages are secured in simplicityv and convenience of constructing and assembling the fixture. An embodiment of my invention is illus 3o trated in the accompanying drawing, in

which:

Figure l is an elevation of my improved fixture. Fig. 2 is a view looking upward.

Fig. .3 is an enlarged view of a. Vdetail in vertical section.

More specifically, 4 indicates a'fixture pipe or conduit suitable fon carrying electric wires. A coupling is indicated y 5 and comprises a member of ring. form provided with a threaded aperture 6. The aperture 6 `is of such size as to receive the pipe 4.

\ Threaded bores 7. are provided on the cylindrical surface of the coupling 5 for receiving set screws. Coupling 5 .serves a's a support p for an annular frame 8 in the form of a shell .having an interiorly disposed flange 9 forming a shoulder for supporting a reflector. The frame 8 may have its surface ornapartly in section mented as found convenient, 'and may be of such configuration as willbe artistic'.

Arms 11 are secured by means Vof set screws 7 to the coupling 5 and at their lower ends by suitable screws to'the frame 8. De-

.: pending from the coupling 5 is a'pipe orA have invented new and l.shell 14 which lisprovided at its upper end diffused throu conduit 10 forming in effect a continuation of the pipe 4, and with the pipe 4 forming a fixture su port..

Mounted upon the pipe l 0 is a bell shaped with a collar 125. and meals for detachably securing it to the coupling such as a set screw 13. In the walls o1 the shell 14 are screws. 15 threaded in apertures in the wall of the shell. The screws Li are for the. purpose of securing thef refiect )r thereto. l

A reflector 16 of conoidsl form having at its center an opening thlough which the lamp socket and bqwl sul )porting shell is adapted to extend, rests zt its outer edge upon flange 9. Reflector 1i has' an annular lip 17, thereby providing a groove in which the screws 15-ma be dispos ed.

An inverted wl 18 .is secured to the fixture by means` ofa shell 19 which` is provided with a collar 20 to s ip over the pipe 10. Secured to shell 19', 4which is of bell form, and at the edge th ireof are 'downwardly depending arms 22 which extend outwardly. The up er ends of these arms 80 are bent to form hoollfs 23 w hich are adapted to engage in apertures 24 formed in the lower peripheral edge of t 1e bell 19. The above construction is one cf the important features of m invention in that the hooks on the ends ofY the sup orti Jg arms 22 may be detached from the ll und the bowl 18 readily removed. The arms 22 extend down'- vvar'dlyA and outwardly from the shell and are passed through apertures in the bowl 18. The ends of the arms 22 are preferably threaded and have mounted thereon jam nuts`25 adapted to abut the inside surface of the bowl. Balls 26 are provided` with threaded apertures which 1:c1'ev\ upo'nfthe arms 22 and are adapted to ibut the outside? of the bowl 18.

Secured to the pipe 10 and" dependin therefrom is a lam socket 27 which is- 0% the usual form an is dis used with-in the shell 19. The socket is a tpted to receive an incandescent lamp 28wl1ch is 'Sposed within the bowl 18. ThehowllS ay be constructed of translucent 4glassfsp hat a portion of the light will be iransniitted and h theA bowl and some reflected upwardy.

Light rays'coming from thesource of light and passing upward ab ove the edge of the bowl ico will strike the reeztor surface 16, l y

some of the light rays being deflected downwardly. Other of these rays pass upwardly through the transparent reflector and to the ceiling,' if the fixture is disposed directly 5 below the ceiling. The latter rays are rcsource of light outwardly and iinpiiiging upon the surface of the bowl 18 will pass directly through the bowl and illuminate the portions of the room below the fixture. Other of these light rays emanating from the source of light and iinpinging upon the bowl 18 will be reflected upwardly and strike the transparent reflector 16, some of these passing therethrough to the ceiling -and others reflected downwardly into tlie room. *i*

It is obvious that the light rays by my construction are diffused so that -a uniform soft light is produced, The easy. disassembling ofthe fixture 16 is apparent from its construction. The bowl l8-and arms QZ'may vbeunhooked from bell 19 and removed therefrom.V The bowl 18 maybe removed from the arms22 by unscrewing the balls 26 and pressinfr the arms inward out of the aperture. The socket 2.7 may thenbe unscrewed from the pipe 10 and shell 19 removed. Tlie set Screws l15 are moved out of engagement with the groove in reflector 16 whereupon the shell 14 may be raised. By unscrlwing the screws upon the arms 11 which secure the frame 8 to the latter the frame may be dropped and the reflector 16 removed.'
