SPECIFICATION forming part of Letters Patent No. 559,946, dated May 12, 1896.

Application iiled April 26, 1895. Serial No. 547,211. (No model.)

To @ZZ whom it Huey concern:

Beit linown that I, FRANK RHIND, a citizen of the United States, residing at Meriden, in the county of New IIa-ven and State of Conneeticut, have invented certain new and useful Improvements in Bicycle-Lanterns; and

I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to 1o whichit appertains to malte and use the same.

My invention relates to bicycle-lanterns, and has for its object to provide a construction which shall insure that air admitted at the back shall pass to the combustion-chamber both above and below the vllame, thus equalizin g the air-currents, so that danger of the flame being extinguished by sudden and powerful drafts shall be wholly done away with.

lYith this end in view I have devised the novel construction of which the following description, in connection with the accompanying drawings, is a specification, numbers and letters being used to designate the several parts.

Figure l is a side elevation of a bicycle-lantern, the shell being partially broken away to illustrate the manner in which I have carried my invention into effect; and Fig. is a 3o section on the line y y in Fig. l, looking toward the back.

My invention consists in the construction substantially as hereinafter described and claimed.

l denotes the body of the lantern 5 2, the reservoir; 3, the combustion-chamber, and etthe burner, which may be of any ordinary or preferred construction and which lies within the combustion-chamber.

l1 denotes openings in the back of the combustion-chamber near the top and bottom thereof, the essential principle being that these openings shall be located above and below the burner and only at the back, so that 4 5 air entering the combustion-chamber at these openings will enter above and below the flame simultaneously and without undue force due to side draft, thus equalizing the currents in the combustion-chamber. In other words, air must pass into the combustion-chamber at both top and bottom thereof, so that the downward current from the opening ll near the top of the combustion-chamber, which would tend to extinguish the iiame, is equalized by the current entering the opening ll near the bottom of the combustion-chamber, which moves upward, so that the flame is practically unaffected by the currents. This equalization of the aircurrents insures a steady flame and prevents flickering under all ordinary and extraordinary conditions. In order to insure that strong currents of air shall not enter the combustion-chamber ateither of the openings 11, and also to insure that the passage of strong currents of air across the body on the Outer side thereof will not produce the effect of exhausting air from the combustion-chamber and cause an outward current which would make the flame unsteady, I provide an air-duct A, consisting of back, side, top, and bottom walls, (indicated by 9,) said duct being located entirely at the back of the body l. The side walls of this duct are located close to the ends of openings ll, and are shown as provided with openings 10 for the passage of air into the duct. The eect of these openings, however, is to break up any strong air-currents. The air in fact enters the duct at any or all of the openings lO, but can pass from the duct into the combustion-chamber only at the openings 11 at the top and bottom thereof, there being in fact two currents, and only two, entering the combustion chamber from the duet at all times, one above the llame and the other below and only at the back of the lantern, thus equalizin g the currents at the burner and preventing the flame from flickering.

Having thus described my invention, I claim- In a bicycle-lantern the combination with a body havin g two openings 1l at the back thereof, one of said openings being above and the other below the burner, of an air-duct A on the outer side of the body which covers said openings and consists of back, side, top and bottom Walls, said side Walls being loeztted the llame, the Currents being thereby equalnear the ends of openings ll and bengthemw ized and flickering of the flame prevented. 1o

selves provided with openings l0 for the en- In testimony whereof I afx my signature trance of air whereby outward Currents from in presence of two Witnesses.

Chamber from the rearand above and below S. V. RICHARDSON.
