PETER COOPER HEWITT, on NEW 03.11, N. Y., ASSIGNOR T cooPEE HEWITT ELECTRIC COMPANY, A CORPORATION NEW YORK.
VAPOR-LAMP WITH CONCENTRATED RADIATION.
I Specification of Letters Patent.
Patented Aug. 2,1910.
ipiflication filed March 19: 1903. Serial No. 148,503.
To all whom it may concern:
Be it known that I, PETER COOPER HEWITT, a citizen of the United States, and resident of New York, county of New York, State of New York, have invented certain new and useful Improvements in Vapor-Lamps with Concentrated Radiation, of which the fol-' lowing is a specification.
The gas or vaponelectric lamp which is now well-known in the art has generally been constructed in such shapes and forms as would aflord large surface of radiation in distinction from a compact or concentrated source of radiatlon. For example, these lamps have often been manufactured in the form of long transparent tubes where.-
in the inclosed gas or vapor is made luminous by the passage of electric current, ex-- tends through a sultable space, anddoes not flector forming a umtary structure with the lamp itself. I prefer to so shape the lamp tube itself as to concentrate the surfaces from which the radiation emanates, as will presently appear.
The invention is illustrated in Figures 1 Witnesses:
and 2 which are, respectively, a perspective and a bottom View of one embodiment of this invention.
In the drawings, 1 is the vapor tube,.and
2 is a reflector to which the ends of the tube are joined by any suitable means. The centersurface of the reflector should be suitably polished and capable of reflecting the radiation thrown upon it in directions determined by the curve on which the reflector is constructed". The electrodes 3 and 4 of the lamp are held within a cap, 5, and may be connected with the external circuit from which the supply (if current is obtained.
An eye-piece, 6,
cap 5 may form a convenient means of attachment to any suitable support.
I claim as my invention:
The combination with a vapor lamp of the character described, the tube of which is arranged in an S-shape and its terminals extending upward, of a reflector, and a hood or cover carriedby the reflector and receiving the upwardly turned ends of the tube.
Signed at New York; in the county of New -York, and State of New York, the 17th day of March, A. D. 1903.
