UNITED STATES PATENT OFFICE.
JOHN J. SMOKEY, OF NATGHEZ, MISSISSIPPI.
REFLECTOR FOR SUSPENDED LAMPS.
SPECIFICATION formingpart of Letters Patent N0. 242,999, dated June 14, 1881.
Application filed February 2], 1881.
To all whom it may concern:
Be it known that I, John J. SMOKEY, of
Natchez, Adams county, Mississippi,have inthe effectiveness of suspended lamps.
A represents a ring to receive and support a lamp.
To the outer side of the ring A, and at equal distances apart, are attached the lower ends of three or more small chains or wires, B, the upper ends of which are attached to the reflecting-plate C. The reflecting-plate O is made in the shape of a low cone, and has an aperture, D, through its center, to allow heat to escape from the lower side of the said reflector. The-reflector G is made of copper, tin, or other suitable sheet metal, and is plated upon its lower side with nickel or silver.
To the upper side of the reflector O are attached the ends of wires, rods, or chains E, which have an eye in the center to receive a hook, F, attached to the ceiling to support the reflector and lamp.
(Model.)
To the'wires, rods, or chains E is attached a small concaved plate, G, to receive the heat from beneath the reflector O and deflect it from risingdirectly against the ceiling or other support for the reflector.
The reflector O is designed to be from two to five feet in diameter, according to the size of the room to be lighted, and should be from nine to thirteen feet from the floor, according to the height of the ceiling.
The chains B should be from one and a half to two feet in length to raise the reflector to the proper height above the lamp.
With this construction, when a glass lamp is used" there will be no shadow cast in the room, except upon the ceiling above the reflector.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The reflector G, connected with the lampholder A by chains B, attached. to its under side, and with the ceiling by rods E, having an eye at their upper ends, attached at their lower ends to the top of said reflector, and swinging on a hook, F, from the ceiling, as described.
JOHN JOSEPH SMOKEY.
