IMPROVEMENT IN SAFETY-CANS FOR BURNINGHVFLUIDS. l

Specification forming part of Letters Patent No. 15.206, dated J une 24, 1856.

To all whom t may concern,.-

Beit known that I, SETH E. WINsLow, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and improved method Vin the use of burning-iluids and other explosive mixtures used in cans and other vessels or lamps, so as to prevent or greatly lessen accidents arising therefrom; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing and the letters of reference marked thereon.

The nature of my invention consists in providing a conical wire -cloth strainer, (in vthe drawings marked A,) with one or more small openings in it, (marked 13,) said opening for the passage of a wick or tube, and this conicalv strainer so placed within the nozzle of a can or other vessel, or over the opening of a lamp, as to exclude the flame from its interior. I also make a small tube, open from the body of the can, open to and through the spout of the can, and solder this and said conical strainer into the nozzle of the can, so as to carry up the air or the gas escaping from the vessel being. lled, to supply the vacuum produced by the llow of fluid from the can, and thus prevent all need of unstopping the can, by which unstopping accidents often occur.

To enable others skilled in the art to make and use my' invention, I will proceed to dcscribe its construction and operation.

I cut a semicircular piece of wire-cloth and make a small hole through it, and doubling the straight edge or side upon itself, or bringing the two radii together, it forms a cone adapted to lamps;l or I cut a section of a semicircular piece of Wire-cloth, and folding the edges together, I form the cone adapted to cansland 'Ihe principle upon which the safety of my invention is based is that the smallness of the tube admitting air or gas, or a mixture of both,

to the can will not admit of the fla-meto pass by reason of absorbing or abstracting the heat or `reducing it below the burning-point, and` that the wire-cloth keeps separate to a certain extent the gas contained in the can or the` l lamp from the atmospheric air, and operates inthe same manner or upon the same princi# ple as does the wire cloth or gauze of Sir H.

Davy s safety-lamp, and that the conical form ot' the strainer is best adapted to the top of lamps, to bottle-Stoppers, and to the nozzles of cans, for the following reasons: First, that with a iiat strainer or disk the lamp -is not easily iilled; second, that the cylindrical strainer admits of a partial explosion; third, that a conical strainer lights when ignited, as does avwick or a cup wet with burning-fluid;

fourth, that through the conic strainer the toni of the'spout of cans, or a long tube of wirecloth extending to the bottom of a lamp, or as forming part of said tube, for this use of it has been made by others; but

What I claim as my invention, and desire to secureby Letters Patent, is-

The conical form of the wire-cloth strainer, with a small aperture at its apex or side, which may be adapted to the lower part of lamp -tops and to cans; and I do hereby disclaim any application of said conical strainer to the cap of a lamp, with an oriice in said cap through which the lamp may be filled. f
