LIGHT‘ REFLECTOR
Joseph Thomas Norton, Swedesboro, N. J.
Application October 14, 1937, Serial No. 169,019
3 Claims.
(Cl. 240—103)
This invention relates to re?ector means for
electric lights, the‘general object of the invention
being to provide means for preventing glare from
the lamp and materially increasing the illumina~
tion of a room or the like.
This invention also consists in certain other
features of construction and in the combination
and arrangement of several parts, to be herein~
after fully described, illustrated in the accom
10 panying drawings and speci?cally pointed out in
the appended claims.
In describing the invention in detail, reference
will be had to the accompanying drawings
wherein like characters denote like or correspond
15 ing parts throughout the several views, and in
which:
Figure 1 is a sectional view through the inven
tion and showing the same in use on a depend
Figure 2 is a top plan view showing a circular
device.
’
Figure 3 is a fragmentary top plan view of the
split collar.
Figure 4; is a transverse sectional view through
51.)1 said collar.
Figure 5 is a top plan view‘ showing a square
shaped device.
Figure 6 is a sectional view showing the inven
tion in use with a pair of lamp bulbs.
Figure '7 is a top plan view of this device.
Figure 8 is a similar view but showing the ends
of the device rounded instead of straight.
In this drawing the numeral l indicates the
re?ector which may be of any suitable shape, such
as the circular shape shown in Figure 2 or the
square shape shown at I’ in Figure 5. This re
?ector has a circular hole 2 in its center and from
this hole the top face of the member slopes down
wardly and outwardly to the periphery or edge of
-i U the member.

light and preventing glare from affecting the
eyes of persons sitting in or walking around the
room.
Figures 6 and ‘I show a device for use with
two bulbs and in this form of the invention
the member I3 is of rectangular shape though
this member may be formed with rounded ends
I3’ as shown in Figure 8. This member is formed
ing lamp.
20
of the rods passing through ears II on the mem
ber 6 where they receive the thumb nuts I2. Thus
these rods detachably hold the device on the lamp
with the lower end of the bulb ?tting in the
hole 2.
Thus it will be seen that the rays of light from
the bulb will pass through the member 3 which
produces a subdued light and the member I will
re?ect some of the light from the bulb upwardly
and outwardly against the ceilingand walls of
the room, thus illuminating the room by reflected
with the spaced circular holes 2’ for receiving the 20
lower ends of the bulbs B which are carried by
the ?xture X, the holes being arranged on the
longitudinal axis of the device and between the
holes the circular portion of the device is straight
but slopes downwardly and outwardly from this
straight portion and the holes. The member I4
is, of course, of the same peripheral shape as the
member I3 and is connected with the edges of
said member by the channel member 6', as in
the ?rst form of the invention and the part I4’ :1.
is made large enough to extend beyond the bulbs
so as to- receive the light from both bulbs. The
supporting rods Ill’ pass through holes in the
parts X’ of the ?xture as shown.
In other re
spects this form of the invention is similar to ;~;_
that ?rst described and it is to be understood
that the invention. can be used on ?xtures con
taining one, two or more bulbs and, of course, the
device will be made to conform to the arrange
ment of bulbs carried by the ?xture.
This hole is of such a size as to
receive a small portion of the lower or outer part
of the electric bulb. B, with the device below the
filament of the bulb. The upper surface of the
member I is made re?ecting in any suitable man
ner so that it will re?ect the rays of light up
be made partially translucent.
While the drawings show the two members
formed of glass it is to be understood that the
wardly and outwardly. A frosted transparent
tive upper surface for re?ecting the rays of light
member 3 is formed with a depending substan
from the bulb upwardly and outwardly so as to
thoroughly illuminate the ceiling‘ and upper por
tially semi-spherical part 4 and a ?at outer part
5 and this member is connected with the member
I by a channel member 6 which receives the edges '
of the two members I and 3 and the ends of the
channel member are connected together by the
bolt ‘I. A slip ring 8 surrounds the lower end of
the bulb socket and has ears 9 thereon through
(r: (a which long rods I0 pass, the threaded lower ends
JII)
If desired the member I or the member I3 can
member I or the member I3 must have a re?ec
tions of the walls of a room.
It is thought from the foregoing descriptionthat
the advantages and novel features of the inven
tion will be readily apparent,
It is to be understood that changes may be
made in the construction and in the combination
and arrangement of the several parts, provided
i

that such changes fall within the scope of the
appended claims.
Having described the invention,
what
is
claimed as new is:—
Cl
1. A re?ector for an electric light bulb com
prising a member having a centrally arranged
opening therein for receiving the lower portion
of the bulb, said member sloping downwardly
and outwardly from the opening and having its
10 upper face re?ective, to re?ect the rays of light
from the bulb upwardly and outwardly, a second
member of translucent material located below the
?rst member and having‘ a depending substan
tially semi-spherical central part, the rest of said
second member being ?at, means for connecting
the members together with the portions adjacent
the edges in contact and supporting means for
the members.
2. A re?ector of the class described comprising
a member having an opening therein for receiving
‘ing the outer portion of a bulb below the ?lament
therein, the member sloping downwardly and
outwardly at such an angle that the ?lament is
hidden from view of a person standing or seated
in a room in which the device is placed, the upper
face of said member being re?ective to direct the
rays of light from the bulb upwardly and out
wardly, a translucent member placed below the
?rst member and having its central portion
formed with a substantially depending concavo
convexed part, the rest of the translucent mem
ber being ?at and a channel member receiving
the edge portions of the two members for connect
ing the two members together.
3. A re?ector 0f the class described comprising
a member having openings therein for receiving 10
the lower portions of lamp bulbs with the ?la
ments of the bulbs above the member, said mem
ber sloping downwardly and outwardly at such
an angle as to hide the ?laments of the lamp
bulbs from view of a person standing or seated in 15
a room in which the device is placed, the upper
face of said member‘ being reflective, a
translucent member placed below the ?rst
member and having its central portion of sub
stantially concavo-convexed shape and depend 20
ing from the rest of the translucent member
which is ?at, a channel member receiving the
edge portions of the two members therein and
supporting means connected with the channel
member.
