5 Claims.
The present invention relates generally to new
and improved lamp shades and to an improved
material for making the same, and an object
thereof is the provision of a lamp shade formed
with exterior opaque, mirror-like reiiective pan
els of metal foil arranged angularly in corru
gated form and provided with translucent spots
in regular geometrical formations so that when
the shade is placed over a lighted electric bulb
a diffused light emanates from the translucent

It is a'further object of the invention to form
a lamp shade of opaque metal foil, preferably
which constitutes the stock for making the lamp
shades embodying my invention.r
' aluminum foil, of a highly reflective nature, and
provided with perforations, openings, or circu
lar holes, arranged in designs, and to laminate
such foil upon its inner side With a solid sheet of
translucent material, such as a thin sheet of ordi
nary paper, and to so arrange the laminated pa
per and foil stock as to obtain mirror-like re
flective foil panels in the lamp shade, which
when illuminated Will by reflection reproduce in
whole or- in part the light rays passing through
the translucent sheet and through the open
ings in certain of the reflective panels.
It is a further object of this invention to ar
range a flat, generally rectangularly shaped
blank of perforated metal’foil, backed with a
' translucent paper, into a generally frusto-conical
or cylindrical shape adapted to fit conventional
, lamp shade frames, corrugating the foil and
paper stock in a series of V-shaped ridges and
35 V-shaped grooves, having sharp longitudinal
crease lines; and to arrange the perforations in
the said foil in longitudinal lines in the crease
lines of the said V-shaped ridges and V-shaped
It is a further object of the invention to pro
vide color eifects in such lamp shades by utilizing
a translucent colored paper of any desired tint
as a backer for the perforated foil, or to attain
generally similar results by placing colored Cel
45 lophane, or similar colored iilms, as a covering or
a lining for the lamp shade.
These and various other objects and advantages
will be readily understood when taken in con
nection with the accompanying drawing of a pre
50 ferred embodiment of the invention, in which
modifications can be made without departing
from the scope of the appended claims.
In the drawing, Fig. 1 is a perspective view of
a lamp shade, illustrating a preferred embodi
55 ment of my invention.
Fig. G is an enlarged fragmentary View of one
of the translucent openings lying in one of the
grooves of the corrugated lamp shade and illus~

In these ñgures a conventional lamp shade
frame I0 illustrated in generally frusto~conical
form has positioned thereon >a lamp shade i2,
and is provided as indicated with an electric bulb
I3. The lamp shade is formed with an outerv
layer of opaque, highly reiiective metal foil, pref
erably aluminum foil, It, and an inner layer of
translucent paper or similar material Iâ which
may be tinted as desired.' The combined metal
and foil stock is deformed into a series of longi
tudinally running V~-shaped ridges I8 and V
shaped grooves 20, giving a corrugated effect,
sharp crease lines 22 being at the apeX of each
ridge I8 -and sharp crease lines 24 being formed
in the bottom of each groove 20. Such forma
tion provides substantially rectangular panels 26 35
of a highly reflective or mirror-like character
running longitudinally of the shade I2 which
Will ordinarily be of equal size, and the adjacent
panels 26 in any one groove 20 will ordinarily
be arranged so as to be at an angle of substan- 40
vtially ninety degrees, or preferably less, one to
the other.
The outer layer of foil I4 in the embodiment
of my invention illustrated, is provided with a
series of perforations 28 arranged in longitudinal
lines at the ridge crease lines 22 and at the groove
crease lines 24; the translucent paper stock is
visible through perforations 28, and being of dif
ferent «color .than the foil layer I4, clearly shows
as a series of paper spots 30.
The perforations 50
28 will normally be formed in a regular pattern,
spaced equidistant one from the other, or in some
design, as illustrated. Where the shade is gen
erally cylindrical in form, each panel 26 Will lie
in substantially a single plane, and this is sub- 55
stantially true of the panels 26 as illustrated al
though the frusto-conical shape of the lamp
shade l2 causes the individual panels 22 to vary
slightly from lying in a single plane due to the
fact that the angle of V-shaped groove 20 tends
to `be slightly smaller at the top of the shade than
at the bottom; however, for all practical pur
highly reflective metal foil and an inner layer of
translucent material mounted thereto, which in
cludes openings in said outer layer and reflective
panels formed in said outer layer angularly dis
posed one to another and positioned to reflect
poses, the individual panels 26 are and will be
of highly reflective metal foil having a plurality
designated as each lying in a single plane, and
this application is intended to include such panels
in generally cylindrical lamp shades, as shown.
When lamp shade l2 is illuminated translucent
paper spots 30’ will glow with light and certain
light rays will emanate therefrom. Certain of
the illuminated spots and light rays will be re
flected in panels 26 depending upon the position
of the observer. Referring to Fig. 3, if the ob
server is directly in front of the lamp shade, spots
of openings and an inner layer of translucent
material mounted thereto and co-extensive there~ 10
30 located in grooves 20 in' the Zone indicated as
20 “A”, will be reflected in the panels 26 of such
zone; in zone indicated as “B” the translucent
spots 36 in both the ridges I8 and in the grooves
20 Will be reflected; in the Zone “C” there will
be reflections of the illuminated spots 3Q of the
ridges I8 only.
Reflection of light through and the illumination
of the paper spots 30, together with reñections
thereof in the highly reflective or mirror-like
panels 26, give a soft and diffused light from
30 the shade. The brightness of the metallic foil
and the soft glowing of the translucent spots
3l? together give an attractive and unique ap
pearance, which may be modified by placing an
outer covering, indicated as 32, of colored Cello
35 phane upon shade l2.
It is to be understood that while the illustrated
form of the invention which I have described,
represents a preferred embodiment, I do not wish
to limit myself to the details as shown, since it
40 is obvious that the same may be widely Varied
without departing ‘from the essence of the in
vention which comprises the mounting of tra-ns
lucent material upon an outer layer of highly
reflective metal foil having openings therein and
45 arranging a lamp shade with a series of reilec
tive panels adapted .to reflect light showing
through the translucent material spots in the said
openings, and therefore the appended claims are
intended to define the scope of my invention.
Having described my invention, what I claim as
new and desire to secure by Letters Patent is:
l. A lamp shade comprising an outer layer of
light emanating from said openings.
2. A lamp shade comprising an outer layer
with so as to cover said openings, which includes
a series of reflective panels formed in the said
shade disposed at an angle of ninety degrees, or
less, one to another, so that light emanating from
said openings is reflected in said panels.
3. A lamp shade comprising an outer layer of
highly reñective metal foil and an inner layer
of translucent material mounted thereto, which
includes a series of adjacent light reflective panels
each lying substantially in a single plane and
each angularly disposed to the panel directly
adjacent, said panels being arranged to form
alternately V-shaped grooves and ridges, .and
openings through said outer foil layer but not
through said translucent layer, the said openings
being formed in regular designs approximately
in the bottoms of the grooves and at the tops of
the ridges.
4. In a lamp shade, an outer layer of highly
reflective metal foil, an inner layer of translucent 30
material mounted to the said foil, a series of
corrugations in said layers alternately forming
‘tl-shaped ridges and grooves, >and openings
formed in said outer layer of reflective foil only,
whereby light passing through the translucent
material and through said openings is reflected
in said outer reflective foil.
5. In a generally cylindrical lamp shade, an
outer layer of highly reflective foil, an inner
layer of translucent material mounted thereto, a
series of equal and alternate V-shaped grooves
and ridges corrugated in the said layers, form
ing a series of light rellective panels upon the
exterior of said shade, openings in the foil layer
but not in the translucent layer disposed ap 45
proximately in the bottoms of the grooves and
at the tops of the ridges thereby forming spots
of translucent material through which light rays
may pass, capable of being rellected in said re
flective panels.
