INDIRECT LIGHTING FIXTURE Filed Aug. 8, 1930 /6 7 ig flllllllllllll@-llllli I INVENTQR I [gay aipoane ATTORNEY Patented June 7, 1932 STATES LEROY C. DUANE, F MERIDEN, CONNECTICUT, ASSIGNOR TO THE MILLER COMPANY, OF MERIDEN, CONNECTICUT, A CORPORATION OF CONNECTICUT INDIRECT LIGHTING FIXTURE Application filed August 8, 1930. Serial No. 473,812.

The present invention relates to indirect lighting fixtures.

The present invention contemplates an enclosed lighting fixture or lighting unit where V in the lower member of the lighting unit (generally made of metal) is detachably secured to a frame in such a manner that it may be lowered to permit lamp renewal without being completely disconnected.

I An object of the present invention is to provide an enclosed lighting unit with an enclosed frame adapted to receive the lamp bulb and to provide this frame with means for se curing the lower reflector member either in position to close the bottom of the lighting unit or suspending in a position to permit access to the lighting unit, at which time the frame and parts may be adjusted to permit lamp renewal.

The accompanying drawing shows, for purposes of illustrating the present invention, one embodiment in which it may take form, it being understood that the drawing is illustrative of the invention rather than limiting the same. J In this drawing:

Figure 1 is a sectional view with parts in elevation showing one form of enclosed lighting unit; and

a, Figure 2 is a fragmentary sectional view taken on the line 22 of Figure 1.

The lamp socket for the unit is indicated at 10. It may be secured in any desired manner to the lower end of the suspending elew; ment 11 which also carries a socket cover 12. The socket cover carries a frame having three downwardly extending straps 13, divergent as indicated, and connected at their lower ends with a narrow horizontal band 14. This frame is somewhat larger than the lamp bulb which it is intended that the fixture shall employ. It is detachably secured to the socket cover by screws indicated at 15 and the parts are riveted together at their lower ends, as

v; indicated in the drawing.

A U-shaped strap 16 is also riveted to the band 14:. This strap is of slightly larger radius than the band 14, so that it may be swung upwardly, as indicated in dot and dash to lines in Figures 1 and 2. This U-shaped member carries a downwardly extending threaded stud 17 which is arranged axiallv of the lighting unit when the U-shaped member is in its lowermost position. The lighting unit is preferably provided with a glass cover plate 20 which is fixedly secured in place between the socket cover and the bent portions 21 of the straps 18, so that the glass plate remains in position at all times.

A dished sheet metal stamping 22 is provided to close the bottom of the lighting unit. This stamping has a central aperture to receive the threaded stud 17, and a nut 23 is threaded onto the projecting end of the stud to support the reflector stamping and to force its upper edge 24: against the lower edge 25 of the glass plate, thereby making a tight, substantially dust proof fixture.

In order that the reflector may be supported when the unit is being opened for lamp renewal, the unit is provided with a link 27, pivoted at 28 and 29 as indicted. When the nut 23 is removed, the reflector and link hang downwardly, as indicated in dot and dash lines, whereby the fixture may be readily relamped or cleaned without having hold or supporting any of the parts while carrying out these operations. The link may be omitted if desired.

It is obvious that the invention may be embodied in many forms and constructions within the scope of the claims, and I wish it to be understood that the particular form shown is but one of the many forms. Va rious modifications and changes being possible, I do not otherwise limit myself in any way with respect thereto.

I'claim:

1. An enclosed indirect lighting fixture comprising a downwardly opening lamp socket, a lamp bulb in the socket, a socket cover, a glass cover plate secured to the socket cover, a frame secured to the socket cover and extending downwardly about the lamp bulb, a reflector of at least as large an outside diameter as the cover plate, the frame including a hanging yoke normally underneath the lamp bulb, and means for detachably supporting the reflector from the frame with the edges of the reflector and cover plate together,

the yoke being swingable to position it to one side of the lamp bulb to facilitate bulb renewal.

2. An enclosed indirect lighting fixture comprising a downwardly opening lamp socket, a lamp bulb in the socket, a socket cover, a glass cover plate secured to the socket cover, a frame secured to the socket cover and extending downwardly about the lamp bulb, a reflector of substantially the same outside diameter as the coverplate, means for detachably supporting the reflector from the frame with the edges of the reflector and cover plate together, and suspension means connecting the frame and reflectorto allow the reflector to hang from the frame when the first means is disconnected.

3. An enclosed indirect lighting fixture comprising a downwardly opening lamp sock- :et, a lamp bulb in the socket, a socket cover,

a glass cover plate secured to the socket cover, a frame secured to the socket cover and extending downwardly about the lamp bulb, a reflector of substantially the same outside 1 diameter as the cover plate. means for detachably supporting the reflector from the frame with the edges of the reflector and cover plate together, and a link connecting the frame and reflector, the link supporting the reflector in a hanging position when the supporting means is disconnected, and being so located as to not interfere with lamp bulb renewal.

4. In an indirect lightingfixture, a lamp socket, a socket cover, a glass cover plate supported from the socket cover, a frame supported from the socket cover and adapted to accommodate a lamp bulb with the bulb vertical, a U-shaped member pivoted to the frame and movable to a position to permit inserting the bulb into the frame or to a position where it is underneath the bulb, a depending threaded stem carried by the U- shaped member, a reflector through which the stem projects, and a nut to secure the reflector to the U-shaped member when it is under-. neath the bulb and clamp the reflector against the cover plate.

5. In a lighting fixture, a lamp socket, a bulb in the socket, a socket cover about the socket, a frame secured to the socket cover and including members extending downwardly alongside the bulb and a narrow horizontal ring about the bulb, a U-shaped member pivoted to the frame to swing about a horizontal axis and movable to one side of the frame to permit lamp bulb renewal, or to be below the bulb, a reflector, means to support the reflector from the U-shap-ed member when it is below the bulb, and a link connecting one of the frame members and the reflector to support the reflector when said supporting means is disconnected.

6. An inclosed lighting unit comprising an upper glass cover plate, a dish shaped sheet metal stamping, an inclosed frame having a downwardly extending threaded extension passing through a hole in the stamping, a nut for clamping the stamping against the glass plate, and a link connecting the outer part of the stamping and the frame to suspend the stamping when the nut is removed.

7. In a lighting fixture a lamp socket, a socket cover, a lamp bulb in the socket, a frame secured to the inside of the socket cover and including members extending downwardly alongside the bulb and a U-shapcd member pivotally supported from the downwardly extending members and movable to one side of the center to permit lamp bulb renewal, a glass cover plate supported from the upper part of the frame and extending within the socket cover, a threaded stud carried by the U-shaped member, a lower reflecting member engaging the outer edge of the glass cover, and a nut on the stud for clamping the reflecting member against the cover plate.
