Referring now inTdetail to the‘ drawing, Ill
45,, designates a lighting, ?xture embodying the in
vention suspended-from the'ceiling ll.
ture Ill ‘comprises a cylindrical member I2 made
of sheet metal, preferably‘ polished or chromium
surface of-theplate 20.
The spherical portion 24 of the member 23 is
furthermore formed with a plurality of horizontal
equi-angularly spaced threaded openings 32, into
which are screwed lamp sockets 33 extending in
radial direction. Lamps 34 may be screwed to
the sockets 33. Although three sockets for the'
reception of three lamps are shown in the draw
ing, it will be understood that any suitable num

ber of sockets may be provided. The member 23
valso has, at the top thereof, a vertical screw
threaded opening 35 and an annular shoulder 36
plated on the outer surface‘. ,The member [2 may 7' surrounding said opening.
Screwed within the

of the member I2 is an annular bead l3 having 39, resting on the shoulder 36 and preferably
a peripheral radial groove M on the underside
55, thereof into which the upper edge l2a of the
cylindrical. member I2 is frictionally received.
The head I3 may be made from an elongated
piece of round wire stock groovedlongitudinally,
?tted over the edge of the strip of metal of which
' 60 the member i2 is made and then bent with said
polished on its outer surface. A cup-shaped
member 40 is received‘on the tube 39 and ?xed
thereto by a screw 4|, the upper edge of‘ the cup
being in contact with the ceiling. The wiring
from the junction box 38, passes through the
nine 31 and the member‘ 23 to the sockets 33.
The lamps 34, as shown in the drawing, are 60

located directly above the mirrored plate ll and
within the cylindrical member [2. The light
from said lamps are re?ected upwardly by the
mirror I‘! to the ceiling. It will be noted that
the only connection between the plate I‘! and
the ceiling, is at the center of the plate, hence
eliminating shadows usually caused by connect
ing members disposed above the lamps, as in
lighting ?xtures now in use.- The plate ll, be
10 ing ?at, re?ects the light upwardly without any
substantial loss over a wide area on the ceil
ing. The colored mirror Zil re?ecting light down
wardly enhances the lighting e?ects produced
by the lighting ?xture. I have found that with
my improved lighting ?xture a particularly soft
and. pleasant light is produced for illuminating
a room.
a
The plates H and 26 may be removed or re
placed readily by merely unscrewing the nut
28 which permits the stem 25 to be lifted out
of the openings l8 and 25. Should either of
these plates break, replacing is greatly facili
tated. by reason of the engagement of said plates
with opposite sides of the ?ange IS.
The mirror plate 20 re?ects downwardly all
the light rays impinging thereon. When the
lamp I0 is illuminated, the light is re?ected up
wardly by the mirror H. The rays of light are
re?ected to the various walls, the ?oor and fur
niture within the room which in turn re?ect light
to the plate 20 and said plate re?ects said re?ect
ed light downwardly.
There are no direct rays
from the lamps 34 to the plate 251, but the light is
re?ected around the room and ?nally reaches
the plate 29. Furthermore the plate 20 serves
to cover the undersurface of the mirror plate M.
_It will thus be seen that there is provided a
device in whichv the several objects of this in
vention are achieved, and which is well adapted
,to meet. the conditions of practical use.
As various possible embodiments might be
made of the above invention, and as various
changes might be made in the embodiment above
set forth, it is to be understood that all matter
,herein set forth or shown in the accompanying
drawing is to be interpreted as illustrative and
