Lamp Chimney.
Patented June 13,1854.-
PATENT OFFICE.
SILAS CONSTANT, OF BROOKLYN, NEW YORK.
LENS LAMP-CHIMNEY.
Specification forming part of Letters Patent No. 1 1,060, dated June 13, 1854.
T0 aZZ whom it may concern.-
Be it known that I, SILAS CONSTANT, of Brooklyn, in the county of Kings and State of New York, have invented a new Lens Lamp- Chimney; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing, representing a vertical section rection, substantially as hereinafter set forth.
My invention is applicable to all forms of lamp-chimneys, and does not vary their construction, except in the part A, surrounding the flame of the lamp or gas-burner, which portion is formed into an annular lens. The
lens may have a concavo-convex section, as
shown in the drawing, or a plane-convex or doubly-convex section, as may be most convenient or best accomplish the desired purpose, and of any degree of convexity to attain the particular object in each case; but no general rule for constructing the lenses can be given. The chimney is placed around the flame in the usual manner. By means of this arrangement all the light passing through the lens may be refracted, so as to appropriate itforilluminating any given space, and thereby greatly increase the light where desired, which would otherwise be uselessly'dispersed.
What I claim as my invention, and desire to secure by Letters Patent, is-- Constructing alamp-chimney with the bulge so thickened as to form an annular lens for retracting the rays of light, as herein de scribed.
SILAS CONSTANT. Witnesses:
Z. G. ROBBINS, J. S. BROWN.
