SPECEFICATION forming part of Letters Fatent No. 687,301, dated November 26, 1901.

Application filed December s, 1900. Serial to. 39,147. on model.)

To all whom it may concern.-

Be it known that I, JOHN G. FLEMING, a citizen of the United States, residing at Summit, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Globes or Shades for Incandescent Electric Lights, of which the fol lowing is a specification.

My invention has relation to a globe or shade for an incandescent electric light; and in such connection it relates to the construction and arrangement of such a globe or shade. r

The principal object of my invention is to provide a globe or shade for an incandescent electric light comprising a plurality of transparent or translucent hollow bodies or shells adapted when properly connected with each other to receive the light within the interior of the inner body or shell and also adapted to receive and retain between the contiguous walls of adjacent bodies or shells a colored or other fluid or material.

The nature and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in which- Figure 1 is a vertical central sectional View of a globe or shade embodying main features of my invention, and Fig. 2 is a top or plan View partly broken away and sectioned to more clearly illustrate the construction andarrangement of the globe.

Referring to the drawings, a and b represent two transparent or translucent hollow bodies or shells of preferably conoidal shape and forming the main portion of the globe or shade for an incandescent electric light d. Each body or shell a and b is flanged at its upper open end, as at a and b, so that each body or shell is provided with an annular rim projecting outwardly from its top. Between the rim a of the inner body or shell a and the rim b of the body or shell 27 is in-- terposed an annular washer e, and to this washer e the flange b is clamped by a screw-ring f, which fits under the rim Z). The inner body or shell a is clamped to the washer e and to the screw-ring f by means of asecond screw-ring g, which screws on the exterior of the ring f and has a flange g,

plate has a centrally-disposed socket-piece V or bushing It" internally screw-threaded to receive the shank d of the electric light (I, as clearly illustrated in Fig. 1. By this means the light d is suspended from the plate 20 and is removable therewith from the other parts when the nuts h are removed from the bolts h. Below the plate It is arranged a reflectorplate on, of silvered glass, metal, or other suit able material. This reflector-plate m is preferably suspended from the cover-plate k by providing the reflector-plate m with a series of prongs or fingers m, adapted to enter suitable slots in the cover-plate 7c and to be bent down upon said cover-plate. Between the contiguous walls of the two bodies or shells at and b aspace or chamber is formed, and this space is adapted to receive a liquid or solid 19 of a transparent or translucent nature and of any suitablecolor. When the parts are all assembled together, as illustrated in Fig. 1, a double-walled transparent or translucent hollow body is formed, the space be= tween the walls of which is adapted to receive and retain the transparent medium 19'. Having thus described the nature and ob ject of my invention, what I claim as new, and desire to secure by Letters Patent, is=

1. The combination of a plurality of bodies, between the adjacent walls of which is a space, a cover-plate detachably secured to the upper ends of said bodies, a source of light in the region inclosed by said bodies, and a reflector depending from said cover-plate within said region and interposed between said coverplate and source of light. 2. The combination of a plurality of bodies having flanged upper ends, a washer interposed between contiguous fianges of said bodies, a screw-ring adapted to clamp one flange to said washer, a second screw-ring adapted to engage the first ring to clamp the other flange to said washer, and a cover-plate spanning the region inclosed by said bodies.

3. The combination of a plurality of bodies having flanged upper ends, a coverplate spanning the region inclosed by said bodies and detachably secured to the flange of one of said bodies and a source of light projecting downward from said cover-plate within said region, and a reflector depending from said cover plate and interposed between said cover-p1ate and source of light.

4. The combination of a hollow body, a cover-plate spanning the upper end of said JOHN C. FLEMING.
