Description
'UNITED STATES .PATENT Carica.
JAMES F. TRAVIS, OF NEW YORK, N. Y., ASSIGNOR TO ARCHER AND PANCOAST MANUFACTURING COMPANY, OF SAME PLACE.
iMPRovl-:M ENT IN LAMPSHADES.
Specication forming part of Letters Patent No. 90,135, dated May 18, 1869.
To all whom it may concern.-
Be -it known that I, JAMES E'TRAVIS, of
the city, county, and State of New York, haveV y form part of this specification, and in which is represented a vertical section of a shade constructed according to my improvement, and
a applied to a gas-burner.
This .invention consists in a translucent disk applied to the bottom ofthe shade of a gas or other burner for illuminating purposes, whereby the rays of light reilected downward from y the sides of' the shade are partially retracted and mellowed by their passage through the said disk, thereby giving a softer andinore agreeable light.
Referring to the accompanying drawings,
" A is a gallery of ordinary construction, sur
rounding the burnerfor the support of the re! iiecting-shade B. C is the translucent disk, constructed of ground glass, mica, or other translucent or semi-transparent material, and having a central opening through it to allow of its'being passed over the burner. It is made to correspond in size and form with the bottom of the shade. It is rst placed upon the gallery, and the shade placed over it so as to rest upon it, as represented. It may be flat, as represented, or of concavo-convex or inverted conical form.
By means of this inventiona softer an d more uniformly-concentrated light is obtained than by the ordinary shade.
Ido not claim a shade constructed with a transparent or semi-transparent bottom; but
What I claim as my invention, and desire to have secured by Letters Patent, is The translucent disk C, made of a separate c piece from, but applied in connection with, the
shade of a gas or other burner, substantially as and for the purpose herein set forth.
