SIGNOBS TO GREIST MANUFACTURING COMPANY, OF NEW HAVEN, CONNECTICUT LAMP Application filed February 26, 1931. Serial No. 518,364.

This invention relates to lamps and more particularly to a lamp having a shade of novel construction and arrangement such that novel lighting efiects will be produced.

In many respects metal lamp shades are superior to glass in that they are not subject to breakage, are more economical to manufacture, and as metal is a more flexible material with which to work, metal shades can be made in a greater varietyof forms and are more readily secured in place upon the lamp. As regards lighting effects, however, glass shades are in some respects preferable to metal shades in that metal shades will usually not be translucent, and therefore will permit no light to pass through the shade. For this reason the outside 'of the shade is not illuminated even when the lamp is lighted, but remains more or less dark, and as a result, figured orcolored effects have not been produced in metal shades.

One object of this invention is the provision of a metal lamp shade upon the outside of which color effects are produced.

Another object of the invention is the provision of a lamp shade of metal or opaque material so constructed as to render the shade translucent in appearance. A still further object of the invention is the provision of a lamp shade so constructed that light from the lamp will be reflected upon certain portions of'the shade by other portions thereof torender the shade translucent in appearance. Preferably the reflecting portions of the shade will be colored so that the surface of the shade upon which the reflected light impinges will partake of'this color, the efiect being that the shade will have a translucent appearance, and may appear to have a color entirely different from the natural color of the shade.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed. I In the drawings:

Fig. 1 is an elevational view of a lamp and lamp shade embodying my improvements;

Fig. 2 is an enlarged sectional view on line 2--2 of Fig. 1,. and

Figs. 8, 4, and 5 areelevational viewsof sections of the lamp shade.

To illustrate a preferred embodiment of our invention we have selected to illustrate and describe an electric lamp having a base 10, standard 11, and a light socket 12 mounted upon the standard, the light socket being pro- Vided with a switch button 13 of usual or ordlnary construction. The lamp socket will receive the bulb 14 in the usual manner.

A sleeve or collar 15 is mounted upon the upper end of the socket 12 and secured thereon by means of a threaded portion 16 on the sleeve which engages with exterior threads 17 on the socket. At the sides of this collar, arms 18 and 19 are secured, these arms extending upwardly and being resilient so that they may .be pressed toward each other by pressure of the fingers in order to mountthe shade thereon. At the upper end these arms are provided with pins 20 to be received in openings in the shade as will appear hereinafter. e

In the form of our invention shown, the shade comprises several sections. We have shown three of such sections in the drawings, although a greater or less number may be employed as desired. The lower or mainshade section 21 is shown in Fig. 5, and comprises a substantially complete shade in itself, which may, asshown, be formed to represent the petals of a flower. While this shade reflects a substantial portion of the light of the lamp downwardly, it is provided adjacent its upper end with a row or series of openings 22 formed on a reduced part of the shade and a second lower row of openings 23. These rows of openings extend vabout the entire circumference of the shade and permit the light to pass through the shade at these points. This section of the shade is also provided with a pair of openings 2 1 to receive the pins 20 on the arms 18 and 19 to secure the shade upon the lamp. j

The shade portion 21 may be provided with a central opening 25 adjacent its upper end through which may pass a threaded member 26 upon which threaded member are received the shade sections 27 and 28. These sections may be spaced apart and spaced from the 7 lower section.

through the openings 22 will also pass through the openings 32 and strike the under'surface of the 'shade 'section 28 It will be seen that the three shade sections are securedtogether in nested, overlapping and spacedjrelation, so that in each case the opening's in the lower shade sections willbefconcealedby a solid portion of an upper shade section. The se'ctions may be con"- venient'ly andf desirably made of metal, and,

whenf the' lamp is not lighted,'willappea'r more" or less like an opaque metal shade of ornamental form; The upper sections will, of course, preferably be constructed to barmonize in form and appearance with the i The undersurface of the upper sections 27 and28 will preferably be colored. We have found that adeep red color gives very desirable effects, although it will be understood N thataiiy' desired color may be used. These portions'of the shade performthefunction of reflecting light upon the 'outer surfa ces' of the lower-shade sections, and, as the under surfaces of these sections are colored, the

lower'surfacesf of the shade will appear to be tingedwith the same color will; present a translucent appearance. The upper sections of the shade are, therefore, primarily to reflect light upon the outer surfaces of the lower sections and to producecolored effects upon these sections.

Itwillbe understood thatthe lightpassing through the openings 23 will be received upon the under surface of the solid portion of the shade section 27 and willloe reflected upon thatportion of the section 21 which is exposed below the section 27. Similarly the light fromthe bulb 14 which passesthrough the openings 22 will also pass through the open- W ings 32 and fall upon the under surface of the solid upper shade section 28. This light will be reflected downwardly upon the lower expo'sed'solid portionof the shade section 27 and will give this portion of the shade a translucent colored appearance.

It will be understo odthat the construction shown is illustrative of the novel principles employed, and that a greateror less num ber of nested, overlapping shade sections may be used,and various'color combinations may be employed as desired.

While we have shown and described a pre-' ferred embodiment of our invention, it will be understood that it is not to be limited to all of the details shown, but is capable of modification and variation within the spirit of the inventionand within the scope of the appended claims.

Vhat we claim is:

1. A, lamp shadecomprising a shadesection. having a series of openings spaced from the'lower edge thereof to provide a lower solid portion and an upper perforate portion, and a second shade section mounted above the first and in spaced relation therewith, said second shade section receiving light upon its under surface through the openings in the first section, said second shade section cover ing the perforate portion ofthe first section but exposing to view the solid portion of the first section.

2.. A lamp shade comprising a shade section having a series ofopenings spaced from the lower edge thereof, andasecond shade section mounted, above the first and in spaced relation therewith with its .lower edge spaced above the lower edgeof the first section, said second shade section receiving light upon its under surface through the openings inthe first section, and said second section having a'solid portion lying opposite and concealing the openings in the first section.

3. A lamp shade comprising a series of shade sect-ions disposed in nested, overlapping relation, each of said lower sectionsbe ing provided'with openings which lie below. and are concealed by. an upper section, and said upper sections receivingfupon their ,inner surfaces light throughsaid openings and ion reflecting it downwardly upon the exposed portion of thesections, the uppermost section eing imperforate and each of the lower sections having a solidportion exposed to view below the edge of the next upper sections.

4. A lamp shade comprising a plurality'ot shade sections one above the other, thelower of said, sections having openings formed therein and the upper of said sections being colored upon its lower surface whereby light is reflected from this surface upon the outer surface of the lower section, and means for supporting the upper sections fromthelowermost section. A

5. A plural part lamp shade comprising sections mounted onetabove the other, and

the lower of said sectipnshavingan upper perforate portion anda'lower solid portion, said perforateportion lying opposite a solid portion of an upper section, and the solid portion of each section being exposed to View.

6. A lamp shade comprising a plurality of sections, means for supporting'the lowermost of said sections from the lampstandard, and means at theltop of said lowermost section for supporting the. upper sections in spaced relation to each other and to. the lowerniost section, the dimensions of said sections being such that the lower portion of each is exposed below the edge of the next uppermost section, the exposed portion of each of said sections being solid, and the lower sections being provided with a series of openings above the exposed portion through which light may pass to the lower surface of the next uppermost section.

In witness whereof, we have hereunto set our hands this 24th day of February, 1931.
