> ELECTRIC‘ LIGHT
Clyde Poling, Fairmont, W.’Va., assignor to West
Virginia Lighting 00., Inc., Fairrnont, W. .Va.,
a corporation of West Virginia
Application April 16, 1937,‘ Serial No. 137,330
'
4 Claims.’ ‘ (01. 2404s) -
This invention relates to light ?xtures and more
particularly to a direct lighting ?xture of the
hanging or suspension type.
The object of the invention is to provide a
direct lighting ?xture of simple and inexpensive
construction capable of being readily attached
to the ceiling of a room or other enclosure and
which will diffuse light in soft mellow rays free
from glare and dazzling radiance and thus insure
‘ maximum illumination and visibility with mini
mum danger of eye strain.
A further object of the invention is to provide
a lighting ?xture including a supporting frame
having an upper ring and a bowl-retaining ring
15
rigidly connected by inclined braces, said retain
ing ring being circumferentially stepped to pro
duce offset portions constituting seats for the
upper and lower bowls of the light ?xture.
-A further object is to utilize the fastening de
vices between the inclined braces and retaining
ring for holding the lower bowl or globe to its
- seat in the adjacent offset portion of the retaining
ring‘ whereby positively to prevent accidental dis
placement of said bowl under all conditions of
service.
i
A still further object of the invention is gen
erally to improve this class of devices so as to
increase their utility, durability and e?iciency.
In the accompanying drawings forming a part
'
Spaced from the annular member 12 and rig
idly connected thereto by inclined braces I3 is
a retaining ring I4 of greater diameter than the
ring I2 and provided‘ with‘circ’umferential steps
or oiiset portions l5- de?ning seats l6 and Il
adapted to receive the upper and lower bowls l8
and I9, respectively, of the light ?xture. The
upper seat 16 is disposed in a horizontal plane so
as to permit the ‘peripheral edge of the bowl l8
to rest flat against the seat while the lower seat
I1 is inclined downwardly to conform to the.
shape of the lower bowl I9. The opposite ends
of the inclined braces l3 are given a half twist
to provide terminal ‘lugs 20 for the reception of
bolts or similar fastening devices 2| and 22 where
by to connect the upper and lower rings together
and form a strong rigid supporting frame for
the glass bowls of the ?xture. The lower fasten
ing devices ~22~extend through the retaining ring
l4 and adjacent lugs 20 of the inclined braces
and are threaded for engagement with clamping
nuts 23. 'By' reference to Figure 4 of the draw
ings,‘ it will be seen that the nuts 23 by engage
ment with. the peripheral edge of the lower bowl
I9-serve to hold the bowl?rmly to its seat I‘! and 25
thereby effectually prevent accidental displace
ment thereof. The fastening devices 22 thus
perform the dual function of securing the lower
ends of the inclined braces to the retaining ring
and locking the lower bowl to its seat. A ?nish
ing ring 24 preferably surrounds the beaded por
of this speci?cation and in which similar numerals
of reference indicate corresponding parts in all
. tion of the upper ring I2 so as to give the ?xture
the ?gures of the drawings:

taken on the line 2-2 of Figure 1, the hanger
‘and its associated parts being shown in elevation,

the line 3-3 of Figure 2 with the upper globe and

Figure 4 is an enlarged detail vertical sectional
view showing the manner of clamping the lower
bowl or globe to its seat.

The improved electric light ?xture forming the
subject-matter of the present invention comprises
' a tubular hanger 5 of any desired length having
its upper end provided with a canopy 6 for at
tachment to a ceiling or other suitable support
and its lower end ?tting with a socket ‘l for the
50 reception of an electric light bulb, indicated at
8. Surrounding the socket ‘I is a casing 9 having
one or more lateral ?ngers Ill riveted or other
wise rigidly secured thereto and adapted to ?t
beneath a head or flange I l formed on an annular
55 member or ring 12.
a neat attractive appearance.
The upper globe
I8 is preferably formed of white translucent glass
While the lower bowl I9 is constructed of pale blue 35
glass with an inner white translucent face so
that, when the bulb 8 is lighted, the light will be
di?used in soft mellow rays free from glare and
dazzling radiance and thereby insure maximum
illumination and visibility without danger of
straining or otherwise injuring the eyes. The
threaded ends of the bolts 22 are preferably of
su?icient length to form auxiliary stops so that in
case the lower globe l9 does not contact the
clamping nuts 23, the edge of the bowl will en 45
gage the threaded ends of said bolts and thus
hold the lower bowl to its seat.
In assembling the different parts of the ?xture,
the lower bowl I9 is ?rst positioned on its seat
l1, after which the lower ends of the inclined
braces l3 are fastened to the retaining ring by
means of the threaded bolts 2'2v and in which po
sit’on the nuts 23 will bear against the periph
eral edge of the lower bowl and lock it to its
seat in the manner before stated.
The upper

bowl I8 is then ?tted over the hanger 5 and
allowed to rest on the ?at seat I6 of said ring
with its upper end resting on the ?ared lower
portion 25 of the annular member l2, as best
shown in Figure 2 of the drawings. The socket
casing 9 is then positioned on the annular ring
l2 by introducing the ears ll] within said ring
and causing them to engage beneath the bed I I,
after which the ?nishing ring 24 is positioned
10 over the bead I I and the hanger and canopy are
attached to the ceiling in any desired manner.
In order to remove or replace the electric light
8, it is merely necessary to elevate the upper bowl
or globe I8 when access maybe readily had to
15 the socket II], as will be readily understood.
An electric light ?xture constructed in accord
ance with the present invention is strong and
durable and will effectually support the glass
globes of the ?xture against accidental displace
20 ment and breakage under all conditions of serv
ice.
Having thus described the invention, what is
claimed as new is:
l. A lighting ?xture including a supporting
25 frame having upper and lower rings, one of which

extending through the stepped ring and the at
taching ears of the adjacent braces, and nuts
threaded on said bolts and bearing against the
peripheral edge of the lower bowl for holding
said bowl to its seat.
3. A lighting ?xture comprising a supporting
frame including upper and lower‘ rings, one of
which is provided with an inclined ?ange and
the other with circumferentially stepped portions
de?ning an upper horizontal seat and a lower in
clined seat connected by an intermediate ?at ver
tical portion, braces forming a connection be 15
tween the rings, an upper bowl having its lower
edge resting on the horizontal seat and its upper
end bearing against the inclined ?ange of the
adjacent ring, a lower bowl resting on the in
clined seat, and fastening devices extending 20
through the stepped ring and the adjacent braces
and bearing against the lower bowl for holding
said lower bowl in engagement with said inclined
seat.

wardly inclined lower seat connected by an in 30
on the inclined seat, an upper bowl resting on
braces forming a, connection between said rings
the horizontal seat, and fastening devices ex
tending through the stepped ring and the ad
35 jacent braces and bearing against the peripheral
edge of the lower bowl for preventing accidental
displacement thereof.
