MANUFACTURE OF LAM P-SHADES.
SPECIFICATEON forming part of Letters Patent No. 352,641, dated November 16, 1886.
Application filed February 17, 1886. Serial No. 192,203. (No model.)
To all whom, it may concern.-
Be it known that I, PATRICK BRADY, of Gambridgeport, in the county of Middlesex, of the Commonwealth of ll/Iassachusetts, have invented. a new and useful Improvement in the Manufacture of Lamp Shades; and Ido hereby declare the same to be described in the fol lowing. specification and represented in the accompanying drawings, of which Figure 1 is a top View, Fig. 2 a side elevation, and Fig. 3 a transverse'and central section, of a lamp-shade in accordance with my invention, the nature of which is defined in the claim hereinafter presented. I
The said shade is made of glass silvered on its inner surface or surfaces. It is concavoconvex, and at its crown has two necks concentric with each other, one being within the other, and the two having an annular space between them and opening into that between the dome-shaped parts of the shade.
The said shadein other respects is composed of two dome-shaped sections united together at their bases, one of which sections extends up within and concentrically with the other, with a narrow space between the two, each at its crown having a cylindrical tubular neck extending up ward from it, as represented.
In the drawings, A and B are the'domeshaped sections; 0 and D, their tubular necks; E, the space between such necks, and F that between the two sections.
After the article or'lamp-shade has been made of glass it is to have silver in a thin layer deposited over its entire inner surface, which may be effected by a process wellknown in the arts. Usually the shade is finished by a suitable metallic annular cap, G, covering the upper ends of the two necks.
This shade is for use with a lamp whose glass chimney is to extend upward through the inner neck of the shade.
I am aware that a glass reflector has been it again at its central part, and by means of a cylindrical plug force each part within the said neck, so as to force within it the inner .neck, after which I out off both necks evenly to the length required. In this case I make no claim for the article.
I claim The process, substantially as described, of making the aforesaid lamp-shade, it consisting in first blowing it in the form of the hollow segment of a sphere with a single neck projecting from its crown, next'heating the basepart and pressing or drawing it within the areal part, so as to form the inner dome therein, next heating this latter at its central part and forcing it inward into the said neck, so as to form the said inner dome with a neck projecting within that of the outer dome, all being essentially as specified.
PATRICK BRADY.
