Patented Oct. 11, 1938 PATENT OFFICE LAMP SHADE CarlY W. Huilage, Chicago, Ill., assignor to Reynolds Metals Company, Richmond, Va., a corporation of Delaware Application May 7, 1938, Serial No. 206,580 Y 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 panels of metal foil arranged angularly in corrugated 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 spots which are reflected in the mirror-like panels to contribute a unique and attractive ornamental effect.

It is a'further object of the invention to form a lamp shade of opaque metal foil, preferably aluminum foil, of a highly reflective nature, and

provided with perforations, openings, or circular 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 ordinary paper, and to so arrange the laminated paper and foil stock as to obtain mirror-like reflective 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 openings in certain of the reflective panels.

It is a further object of this invention to arrange a flat, generally rectangularly shaped blank of perforated metalfoil, 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 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 grooves.

It is a further object of the invention to provide 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 Cellophane, 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 connection with the accompanying drawing of a preferred 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 embodiment of my invention.

Fig. 2 is a plan view of the lamp shade shown in Fig. l with a portion broken away.

Fig. 3 is a semi-diagrammatic side elevation of v the lamp shade illustrated in Fig. with a portion of the same showing the reflective effects 5 obtained when the shade is illuminated.

Fig. 4 is a fragmentary cross-section taken upon the line 4 4 of Fig. 2 but with an additional showing of a colored Cellophane outer coverlng. y 0` Fig. 5 is a fragmentary view of the laminated 1 perforated foil and translucent backing material which constitutes the stock for making the lamp shades embodying my invention.r

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 illustrates certain reflective yeffects secured by my invention.

In these gures 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, preferably aluminum foil, It, and an inner layer of translucent paper or similar material I which may be tinted as desired.' The combined metal and foil stock is deformed into a series of longitudinally 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 formation 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 different 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 generally 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 although 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 purposes, the individual panels 26 are and will be 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 reflected in panels 26 depending upon the position of the observer. Referring to Fig. 3, if the observer is directly in front of the lamp shade, spots 30 located in grooves 20 in' the Zone indicated as 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 reections thereof in the highly reflective or mirror-like panels 26, give a soft and diffused light from the shade. The brightness of the metallic foil and the soft glowing of the translucent spots 3l? together give an attractive and unique appearance, which may be modified by placing an outer covering, indicated as 32, of colored Cellophane 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 is obvious that the same may be widely Varied without departing from the essence of the invention which comprises the mounting of tra-nslucent material upon an outer layer of highly reflective metal foil having openings therein and arranging a lamp shade with a series of reilective 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 highly reflective metal foil and an inner layer of translucent material mounted thereto, which includes openings in said outer layer and reflective panels formed in said outer layer angularly disposed one to another and positioned to reflect light emanating from said openings.

2. A lamp shade comprising an outer layer of highly reflective metal foil having a plurality of openings and an inner layer of translucent material mounted thereto and co-extensive therewith 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 reective 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 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, forming a series of light rellective panels upon the exterior of said shade, openings in the foil layer but not in the translucent layer disposed approximately 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 reflective panels. v
