UNITED STATES PATENT 'OFFICE.
JAMES P. BOESEN, OF HOBOKEN, NEWV JERSEY.
LAM P-S HADEl.
SPECIFICATION forming part of Letters Patent No. 425,735, dated April 15, 1890.
Application filed January 28, 1890. Serial No. 338,326. (No model.)
To all whom it may concern.-
Be it known that I, JAMES P. BoEsEN, of Hoboken, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Lamp-Shades, of which the following is a full, clear, and exact description.
My invention relates to an improvement in lamp-shades, and has for its object to provide a shade which, when fitted over an ordinary framethat of a piano-lamp, for instance will have imparted thereto a conical shape slightly curved inward in the direction of the base or lower edge.
A further object of the invention is to provide a means whereby a shade constructed of a single piece of plainly-colored translucent material, when illuminated, will show upon its outer and inner faces an alternate dark and light tint, and by reason of the construction above referred to the shade will be materially strengthened.
The invention consists in the novel construction and combination of the several parts, as
will be hereinafter fully set forth, and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters and figures of reference indicate corresponding parts in all the views.
Figure 1 is a perspective view of the shade applied to a lamp. Fig. 2 is a partial perspective view of one side of the shade, one edge thereof being in vertical section. Fig. 3 is a vertical section through a portion of the shade, illustrating the position of the folds when the shade is closed; and Fig. 4 is a similar section illustrating the position of the folds when the shade is placed in position upon the lamp. 4
In the drawings I have illustrated the application of the shade to a piano-lamp A, the said shade being supported in position thereon by the ordinary frame B, the hooks thereof and top ring only being visible. The shade is constructed, preferably, of a single piece of translucent fabric-such as silk, a silk mixture, duck, Holland, or like material-the said material being preferably white upon its inner face and colored upon its outer face.
The piece of fabric D having been cut to suitable shape, its ends are united, and either before or after uniting the ends the fabric is creased at intervals to form a series of vertical folds 10, in the usual manner.' In addition to the vertical folds at intervals between the top and bottom transverse seam-like folds 11 are produced, which is accomplished by bending the material twice upon itself, producing in cross-section through the said folds 11 three parallel surfaces-namely, an inner surface a, an intermediate surface a, and an outer surface a as shown in Figs. 2, 3, and 4. The shade is completed by passing a drawstring 12 through the upper portion of the shade and the addition of a fringe, if desired.
Vhen a shade is constructed as above described and placed upon a frame at each transverse fold, the intermediate and outer surfaces incline outward at the top and inward near and at the bottom, thus imparting a decided conical contour to the shade and an inward taper at the bottom. The transverse seam-like folds also serve to stiffen'and strengthen the shade and render it less liable to injury when its sides or ends are brought into violent contact with any object. thermore, when the shade is illuminated and viewed from the outside or from the inside the surfaces between the transverse folds present a light tint, while a darker tint is observed at the said folds, thereby imparting a very pleasing effect not obtained in shades of similar character now in use.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. As an improved article of manufacture, a translucent lamp-shade provided with a series of vertical single folds and a series of intersecting transverse double or seam-like folds, substantially as specified, and for the purpose set forth. Y
,2. As an improved article of manufacture, a translucent lamp-shade having its outer surface tinted and its inner surface of a lighter shade and provided with a series of vertical single folds and a series of intersecting transverse double or seam-like folds, substantially as and for the purpose set forth.
