I 4 1,614,004 1927' L. LARSON MULTIPLE WALL LAMP SHADE Patented Jan. 11, 1927.

' orrsn S T .LOUIS LARSON. on NEW YORK, N. Y."

MULTIPLE-VALID LAlVIl SHADE. I

Application filed December 23,1925. Serial 1N0. 77,244.

My invention relatesto improvements in lamp shades, globes, or the like, and par ticularly has to do with spaced inultiplewalled construction adapted to receive a colored fluid therein, or a colorless fluid, such as water.

One of the objects of the invention resides in the provision oi a globe having means between the reader and the source of light for diilusing and softeningthe rays of the latter.

Another object is to provide a globe having a multiplicity of colored sections, said colored sections being varied at the will of the user.

A further object is to provide a globe or shade which may be inexpensively manufactured, absolutely fireproof, and one presenting a neat and attractive appearance. 7

Other objects and advantages will be apparent as the nature of the invention is better set forth, and it will be understood that changes within the scope of the claim may be resorted to liberally without departing from the spirit of the invention.

In the drawings, forming a portion of this specification and in which like numerals of reference indicate similarparts in the view of my improved globe;

Fig. 2 is a view like unto Fig. 1, but showing the construction for providing a multiplicity of chambers'between the walls and also means for admitting'a current of air through the interior of the globe; and

Fig. 3 is a similar sectional view depicting a shade constructed in accordance with my invention. l

' 'ihe globes illustrated in Figs. 1 and '2 are primarily intended for use in connec tion with electric lighting, while the shade shown in Fig. 3 is especially adapted for gas lighting or kerosene lamps, but, of course, may be used in conjunction with the well-known incandescent lamp and its fix tures.

The construction shown in Fig. 1 com prises a body portion 5, designed with tree flowing curves and fillets to present a stril-zing neat appearance and being circular in horizontal cross-section.

Said body portion consists of inner and outer spaced walls, 6 and 7, respectively, slightly spaced apart to define a chamber'c which extends completely around the sides and bottom of the body portion, and a portion of the top, as clearly shown in the drawing. I provide the top ofmy globe with an upwardly diverging annular rim 9, having a head 10, for connection with a stand ard electric'light fixture (not shown).

Within said chamber 8 may be introduced a colored fluid, or even water, through the aperture 11, the latter being provided with a closure 12 having an opening 13 from which steam generated by the heat from the lamp 14' may escape. While the possibility of such generation is exceedingly remote I prefer to have this opening as a precautionary measure.

In the event wat-er is introduced into the chamber 8, it is obvious that the rays of light passing therethrough. are considerably softened in tone and at the same time said rays are diifused with greater luminosity. For decorative purposes it may be desirable to fill the chamber with colored water of difi'erent hues and thus create beautiful color effects within a room.

The structure shown in Fig. 2 is somewhat similar to that of Fig. 1, but in this instance I provide the globe with a bottom opening 15 to provide ventilation for the interior of the globe, and further I provide the chamher 8 with partitions 16, so that in fact I now have a multiplicity of chambers, each having filling apertures and closures as in my other form. Vhile the drawing shows these partitions 16 as arranged with some degree of regularity, it should be understood that they may bepositioned angularly, vertically and even horizontally in order to provide what might be termed sub-chamhers, each having filling means for the introduction preferably ot colored fluids. In

the drawings these sub-chambers have been lined to illustrate some of the colors which may be used, and it is quite obvious that a judicious use of coloring material therein will result in the production of an article exceedingly beautiful in appearance and at-' tractiveto the eye.

Figure 3 illustrates the body portion 5, having a flared lower portion, and the usual -walls 6.21nd7 defining the chamber 8. This .ing a bulbous body portion embodying parallel spaced Walls defining a narrow chamber therebetween, the outer Wall extending from the top of the body portion and rolling upon itself to define a bottom opening in the body portion, and merging With the inner -Wall, said inner Wall continuing upwardly and having its upper portion diverging to define a flange for sealing the space between itself and the outer Wall and projecting above said outer Wall for attaching the body to a support, and a plurality of annular partitions arranged in the space between said Walls and defining therein a phrrality of chambers each having an inlet for the admission of a colored fluid.

In testimony whereof I aflix my signature.

LOUIS LARSON.
