SHADE FOR |NCANDESCENT--LAMP GLOBES.
SPECIFICATION forming part of Letters Patent No; 536,856, dated April 2, 1895. Application filed June 14, 1894. Serial No. 514,598. (No model.)
I the following is a specification.
My invention relates to reflecting shades for the globes of incandescent lamps, the purpose thereof being to provide a shade, or shade and reflector, suitable for use in connection with the sealed globe of an incandescent lamp, and especially a lamp which is mounted upon a flexible stem, or support, capable of being bent into diiferent positions, or caused to assume different degrees of curvature, my object being to render the shade or shade and reflector, adjustable upon the globe and removable from it, to enable the user to shade the eyes and direct the light to any required point.
My invention consists in the novel featurse of construction and new combinations of parts hereinafter fully described and then particularly pointed out and defined in the claims which make part of this specification.
To enable others to fully understand and to construct and use my said invention, I will proceed to describe the same in detail, reference being had, for this purpose, to the accompanying drawing, in which the figure is a sectional view illustrating my invention.
The reference-numeral 1, in said drawing, indicates the globe of an incandescent lamp, which is made of glass, usually of spherical form, and subject to ornamentation, in any desired manner. The globe l is provided with a neck which is secured, in any suitable manner, in the upper end ofa support, or stem 2 which is flexible and capable of retaining any position into which it is bent.
The concavo-convex shade, or reflector, 10, may be formed of the same material as the globe. I may, also, use a shade, or reflector, 10, made of a different material from the globe. A circular wall, or flange 12, will be formed concentric with, and upon, the concave face of the shade, its diameter being slightly greater than the outside diameter of the globe. In
the inner face of this flange, near its edge, is arranged a cushion 13, of elastic, or semi-elastic material, such as rubber. The depth of the flange 12 is such that when the globe is introduced therein, the cushion 13 will engage the same at, or about, its maximum diameter.
Bythe construction of the support, or stem, the globe may be placed in difierent positions, varying in height and in distance from-the stem. The flexibilityof the hollow, or tubular core permits this adjustment and its strength is sufficient to enable it to maintain any position to which it is adjusted.
The shade, or reflector, thus described is especially adapted to a lamp-support of this kind, as it will not become detached from the globe, in the various adjustments of the latter, and may, itself, be separately adjusted, when made in the form shown, to throw the light, or shade the eyes, as circumstances may require. The adjustments of the shade are shown by dotted lines.
\Vhat I claim is 1. The combination with an adjustable, closed globe for an incandescent lamp, of a continuous, concavo-con vex, reflecting shade, adjustable at different angles upon said globe, said shade having an annular flange concentric with its concave face and projecting therefrom, said flange being provided with a cush- "my hand and affixed my seal in presence of two subscribing witnesses.
