IMPROVEMENT IN LAMP-SHADES.
The Schedule referred toin these Letters Patent and making part of the same.
To all to 'whom .these presents ma/y come:
Be it known that I, MICHAEL H. COLLINS, of Chelsea, in the county of Suiolk andV State oi'Massa 'chusetts, have invented certaiu'new and useful Iznprovemeuts'in Lamp-Shades ;4 and do hereby declare the same to be fully described in the following specilication and represented inthe accompanying drawing, of which- Fgure 1 exhibits a perspective view of the shade as made in accordance with my invention-and axed' to a chimney. l
Figure 2 is a similar view of the superior or spring portion.
Figure 3 is a vertical and central section of the shade as applied to a chimney.
My invention relates to that class of metallic shades in which the springs and body ofthe shade are formed in two separate portions.
In the said drawing- A denotes a chimney.
B is the body of the shade, which is of a frustoconical shape, and may be formed of a disk of metal, (having its center perforated or punched ont,) and pressed into the required sh'ape; or it may be coniposed of one or more segments, properlysccnured together and shaped into lthe frustuin of a cone or pyramid.
C is the superior or spring portion, which i's provided with a series of radial iingers or springs, D'D, &c., of different lengths, whose free ends boar against the outer surface vof the chimney, and by their tension against the same maint-ain the shade in posit-ion thereon.
Thesaid part C may also be formed of' a disk of metal, the central part beingstamped out to form the fingers; or it may be made of one or more segments so shaped and united as to give the desired form.
The two portions B C, so formed, are to be united by riveting. seaming, or soldering, as may be desir. able. Thus it will be seen that the two parts B C of the shade are formed separately, each being' made from a single disk of' metal and afterward united; or each ,part being made up of one or more segments so shaped and connected as to form the frusturn of a cone, and the two parts next secured together.
By forming the two parts separately, and each of a single, piece, the partB may be made from a disk of soft metal spun or pressed into shape, while the part C may be of steel or a hard metal, for giving.1 to the springs a more permanent elastic power.
By making each of' the parts B C independently and of a series of segments, thelower segments may. be composed of a softer and cheaper inet-al than the upper portion or series, which requires a metal of a harder or higher grade, such as will withstand the action of the heat and maintain the norual elasticity of the springs. l 1
rihe body of the shade may he plain or unperforated, and may be painted in any desirable color and ornamented as fancy may dictate.
I prefer to form in the body of the shade a series of perforations, E E, 85e., for two reasons:
First, to render the shade lighter, so that springs of less stiffness or tension are required; and
Second, to relieve the monotony of the shadeby applying to such openings a series ot' ornamental tablets, pictures, or transparencies, F, whereby the beauty of the shade is enhanced.
' The next part of my invention is the peculiar mode of aiiixing the tablets or transparencies to the shade. i
The openings having been stamped' out of the de? sired form, a tablet or transparency of a corresponding shape, Vbut of larger area, and having a coating of gluten applied to its inner face, is to be placed upon the shade over each opening, and so as to overlap its edges.
A corresponding disk of paper or other transparent material, havingan adhesive matter applied to its in- -ner face, is to be placed upon the opposite side ofthe shade and over each opening,` and so as to overlap the edge thereof; or instead of the'backing being ol' a whole piece it may be a circumscribing band applied in a similar manner, so as to overlap theedge of the opening and the adjacent surface of the tablet; or the tablet may be applied to the inner face of the shade, and the re-enforce or circumscribing band applied to theo'uter face. The whole is next to be put in a press and rrnly connected together.
To make a nish to the picture a bead may he.
formed around each opening.
Having described my'inveution.
What I claim is as follows:
l. A shade fora lamp or Argand burner as made in two frusto-conical onpyrainidal portions, C,
formed, constructed, and combined together in inanf ner as set forth.
2. In a metallic shade composed of' a'frusto-conical
