Application filed January 13, 1916.

Z '0 all whom it may concern:

Be it known that I, RICHARD S. Grnsn, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Combined Cylinder and Shade Support, of which the following is a specification.

The present invention relates to an improvement in illuminating devices, and has for an object to provide a cylinder or chimney, of the usual cylindrical construction, adapted to be secured in the usual way to a light fixture. and which at the same time is provided with means for supporting an inverted shade or bowl, without the use of more than one fitter, or any of the supplemental attachments and supports, which are now employed for holding shades about the light and upon the fixture.

Another object of this invention is to produce an arrangement or construction of cylinder and shade, which admits of the application of the semi-indirect bowl to individual electric holders. such as of the incandescent variety.

Another object of the invention is to provide a relatively small structure of this character, which will considerably reduce the expense of manufacture, will reduce the number of parts required forthe assemblage of the cylinders and shades, which produces an easily assembled device, and which is of a neat design and readily applicable.

@ther objects and advantages of this invention will appear from the following specific disclosure of the present preferred embodiment of this invention, the same being shown inthe accompanying drawing, wherein:

Figure 1 is a side elevation of the improved cylinder and shade assembled. Fig. 2 is a central vertical section, taken through the same. Fig. 3 is a horizontal section, taken on the line 33 of Fig. 2, looking downwardly toward the bottom of the cylinder.

The invention provides a construction and assemblage which admits of the use of an opaque or frosted bowl 10 to produce illumination on the semi-indirect principle, and which adapts the application of this principie to individual illuminating electric bulbs. The'bowl 10 constitutes the shade, the refiector for directing the rays of light up weirdly, and serves also as a filter to modu- Speeification of Letters Patent.

late the intensity of the light which passes through the shade or bowl 10 downwardly and radially thereabout. The central portion of this shade or bowl 10, which is the lowest portion of the bowl, is provided with a central opening, the edge of which constitutes a supporting edge for the bowl.

The means for supporting the bowl, without the application of fitters, and other supplemental supports usually projecting from the fixture, comprises an outstanding shoulder or rib 11 formed annularly about the lower end of the cylinder 12, which latter is otherwise of the usual construction. The cylinder 12 is provided with the annular groove 13, by means of which the cylinder 12 is secured to a fixture of any approved type. The lower end of the cylinder 12 is slightly enlarged in diameter to provide this shoulder or head 11, the same being of such size as to prevent the passage of the lower end of the cylinder 12 through the central opening in the bowl 10. The bottom 14: of the cylinder 12, which is closed in the usual manner, is of convex form and which is of such curvature as to preferably conform to the general curvature or configuration of the bowl or shade 10. This lower enlarged portion of the cylinder 12 is made preferably frosted, or made opaque, to filter and modulate the light emitted from the lamp located within the chimney or cylinder 12. The upper portion or body of the cylinder 12 is crystal or transparent, so as to admit the free radiation of the light from the burner. so that there will be no absorption of the light, and so that the bowl 10 will reflect the direct rays of light upwardly, as is necessary in a semi-indirect fixture.

Tn assembling the parts of this improved device, it is only necessary to insert the cylinder 12 upwardly through the central opening in the intermediate lower part of the bowl 10, and to pass the cylinder 12 upwardly in the bowl until the lower enlarged portion of the cylinder, constituting the supporting bead 11, engages the lower supporting edge of the bowl 10. The opening in the bowl is adapted to fit snugly about the cylinder 12, so as to hold the bowl 10 in upright position on the cylinder. As the bottom enlarged portion of the cylinder 12 is frosted, or made opaque, it constitutes the opaque bottom of the bowl 10, and provides a practically uninterrupted continuation of the same. The effect produced is the same as though the bowl were a continuous one piece bowl without a separate bottom or opening therein, and as though it were sup-- ported pendantly from above.

It is, of course, understood that it is within the spirit of this invention to so change the shade and design of these parts above described as to adapt them for various ornamentationsand for various usages found desirable in the actual manufacture and use of the device.

What is claimed is 1. In illuminating devices, a cylinder adapted for securement to a fixture and having an enlarged lower end providing an annular shoulder vthereabout, and a bowl shaped shade having a central opening at its bottom adapted to snugly receive the cylinder upwardly therethrough, the said shoulder being adapted to engage the shade and directly support the same about the cylinder. 5

2. In illuminating devices, a cylinder for securement to a light fixture, having an outstanding shoulder above its lower end and closed atits bottom, and a shade having a central bottom opening to receive the cylinder therethrough and adapted to rest on the shoulder to support the shade upon and about the cylinder, leaving the bottom only.

of the cylinder exposed below the shade.

3. In illuminating devices,'a cylinder of crystal glass adapted for attachment to a downwardly facin fixture, said cylinder having an enlarged bottom to provide an annular shoulder thereabout, the bottom being convexed and opaque, an opaque shade of bowl shape provided with a central opening in itsbottom adapted to receive the crystal portion of the cylinder upwardly I therethrough and to engage said shoulder against the lower end of the shade to support the latter, the bottom of said cylinder conforming substantially to the curvature of the bowl to provide substantially a continuation thereof touniformly absorb and reflect the light radiating from within the cylinder.

4. In illuminating devices, a cylinder, :1 semi-indirect shade fitting around the cylinder to inclose the same, and means on the lower end of the cylinder for engagement with the shade to support the same in inverted position, the,bottom of said cylinder and said shade substantially conforming in curvature and being opaque to provide a practically one piece semi-indirect illuminating bowl.

5. In illuminating devices, a transparent cylinder; and an opaque shade interfitting with the cylinder to support the shade thereon in an inverted position, said cylinder having an opaque closed bottom conforming to the shade to prevent light radiating downwardly through the cylinder.

6. In illuminating devices, a transparent cylinder, and a bowl-shaped opaque shade interfitting with the cylinder to support the shade thereon in an inverted position, said cylinder having an opaque closed bottom which is curved and projects below the bottom of the shade, the shade fitting about the cylinder with its open side faclng upwardly.

In testimony that I claim the foregoing as my own, I have hereto afiixed my slgnature in'thepresence of two witnesses.
