VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 703,661, dated July I, 1902. Application filed August 23,1900. Serial No. 27,791. (No model.)

To aZZ whom it may concern.- I

Be it known that I, AUGUSTELECOMTE, a citizen of the Republic of France, and a resident of 172 Avenue Victor Hugo, Paris, France, have invented certain new and useful Improvements in Liquid-Burners,of which the following is a specification. v

The object of my present invention is toprovide a burner whereby any combustible liq uid-such as petroleum, benzin, tar-benzin, alcohol, or a mixture of these liquids-may be employed for producing light by means of incandescent mantles or for producing heat and light without incandescent mantles.

The invention consists in apparatus for taking heat in the interior of the generatingflame and conveying such heat to a metallic body forming the bottomof a burner. This metallic body is bored lengthwise for the passage of the liquid to be vaporized for burning, said bore containing a filling-plug which may be formed of a metal screw, or of twisted wire, of rolled wire-cloth to furnish a helical external thread. The object of said plugis to lengthen the path of the combustible liquid through the vaporizer in order to lengthen the time said liquid is in contact with the metallic body, whereby the liquid is vaporized,

the vapors being overheated and adapted-t0.

easily mix with air before being burned.

In the accompanying drawings, forminga portion of this specification, Figure 1 shows a burner for producing light by means of an incandescent mantle. Fig. 2 shows the same burner arranged to serve as a heater or as a burner without mantle.

Referring to Fig. 1, A represents the cock of the burner. Bis the vaporizer-tube, adapted to be screwed on the cock. 0 is a cup serving for igniting the generating mixture, placed low down on said tube and surrounding it adjacent to the cock. D is a metallic head formed on the upper endof the vaporizer around the vapor-jet oriflc'efor the purpose of receiving and retaining heat initially from the vaporizer and thereafter through a metallic heat-conductor warmed by the flame, as below described. E indicates a screw made of wire-cloth, constituting the plug of the vaporizer, extending practically from the cock to the mixing-chamber, being separated from the latter only by the nipple F for the ejeca tion of combustible vapors into the mixing or aerating chamber. G represents the forked arms of the heat-conductor H,made of copper, said arms being inclosed within the mantle and exposed to the flame and extending down ward to'a connection, as by solder, with the heat-retaining head D to conduct heat thereto. I is the Bunsen tube for introducing air for mixing purposes, and it may be sustained in the position shown by any suitable supportas,.for instance, by the heat-retaining head D on the upper end of the vaporizer. J is an outer tube having a bell-shaped lower end surrounding the tube I. N is the chimneycarrying socket. O is the crystal chimney. P represents the top of the burner, made of wire-cloth and provided with a central open ring for the passage of the body part of conductor H and shown as capping or supported by the upper rim of the outer tube J. R represents a small washer made of wire-cloth embracing the body part of the heat-conductor above the forks and taking against the inner wall of the Bunsen tube to prevent the burner from making a noise.

In Fig. 2 like letters refer to parts identical with other parts in Fig. 1 indicated by the same letters. Where the parts differ in construction, but are intended to perform the same function, they are usually indicated by letters employed in Fig. 1 on analogous parts, with, however, the addition of the prime. In said Fig. 2 G is the body of the burner, having metallic connection with the heat-retaining head D at the upper end of the vaporizer B and surrounding the vapor-jet orifice to conduct heat to said head in lieu of the forked conductor H of the device shown in first figure. E is the helically-threaded plug in said vaporizer. Ois the generating-cap.v H'shows air-inlets to a mixing-chamber inclosed by body G, and I shows outlets for the-flame. J is the head "or'top of the burner, and K is an annular perforated plate for regulating admission of air to the flame.

The operation of the improved burner is as follows: The cock Abeing shut ofi, alcohol is poured into the cup 0 and then ignited. After a very short time (about forty seconds) the alcohol will be burned. Then the cock is opened and the burner ignited at the top. It will be understood that the heat conductor H, strongly heated by the flame, will convey heat to the metallic body D to restore the amount of heat necessary for vaporizing the combustible liquid in said body. In the construction shown in Fig. 2 the top or head J takes on. the head and the burner-body G conveys same to the vaporizer. When it is desired to put out the light, all that is necessary is to turn 0d the cock of the burner.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A vaporizing-tube arranged for attachment to a supply-pipe at its lowest end and provided with a vapor-jet orifice at its upper end, a screw-threaded plug in such tube extending from its lower end to adjacent the jet-orifice, a metallic heat-retaining head surrounding the upper end of such tube, a Bunsen or mixing tube mounted on such head and provided with a cap at its upper end forming a burner, and a metallic heat-conductor secured to said head and extending axially of the mixing-tube and having its upper end projected through said cap to be heated by the burner-flame.

2. The combination of the cock for admitting liquid, the vaporizing-tube leading up therefrom to the mixing-point,a screw-threaded plug in said tube, extending practically from the cock to said vapor-jet orifice, a cup for the reception of fluid for the generatingflame, surrounding said tube adjacent to the cook, a metallic heat retaining head surrounding the upper end of said tube, a Bunsen tube t'or mixing purposes, a burner above said mixing-tube, a mantle, and a metallic heat-conductor rising centrally in said mantle and having forked depending arms through said burner which are directly attached to the metallic heat-retaining head to conduct heat thereto and continue the process of vaporization in the liquid-passage passing therethrough.

In testimony whereof I have hereunto set my hand in presence of two witnesses.

AUGUSTE LEOOMTE.
