IMPROVEMENT IN VAPOR-BURNERS..

Specification forming part of Letters Patent No. 115,089, dated May 23, 1871.

I, ALANsoN F. NOBLE, of Indianapolis, in the county of Marion and State of Indiana, have invented certain Improvements in Vapor Lamp-Burners, of which the following is a specification Natm'e and Objects of thc Invention.

My invention relates to improvements in that class of lamp-burners in which hydrocarbon liuids are employed and vaporized to produce gas; and it consists in acertain construction and arrangement of the several parts of which the burner is composed, by which it is rendered more convenient to use and more et'- ticient in operation than those heretofore in use, as will hereinafter more fully appear.

Description of the Accompanying Drawing.

Figure 1 is a side elevation of a burner embodying my invention. Fig. 2 is a vertical section through the center ot' the same. Fig. 3 is a horizontal sect-ion through the heater and auxiliary burner, by which the iluid is vaporized.

General Description.

A A A is the stock or principal part of the burner, and to which all the other parts are attached. A is the stem connecting the burner with the fountain or elevated reservoir; A is the body or' the burner, containing the vaporizing-chamber I; and A is the top or upper part of the stock, on which are arranged the mixing-chamber B having the burner H in the top, and the heating-chamber G with the auxiliary burner E, as shown, the parts B,

H, and C E being similar to burners already in use. My first improvement consists in the construction of the stock A A A, which is clearly shown in the section drawing, Fig. 2. The end of the stem A, connecting with the tube leading from the elevated reservoir in which the lluid is placed, is chambered, as shown, for about half its length, to receive fibrous packing, and the remainder ofthe stein connecting with the body A is drilled through, forming a small tube to connect this packingchamber with the vaporiZing-chamber I.

One object ot' this construct-ion of the stemA is to provide a convenient means of renewing the packing when required, as the burner may be readily unscrewed by hand from the tube connectiu g with the reservoir. Generally the stein will be screwed into a stop-cock placed at the end ot' the tube leading from the reservoir, so that by means of the stop-cock the ilow ot' the fluid into the packing-chamber may be fully controlled either with or without the packing.

The advantage of this construction ot' the stem will be better appreciated when it is understood that, on account ofthe varyingquality ot the uid employed, the packing may become in such condition as to entirely obstruct the ilow through it into the vaporizing-chamber I, in which case the burner may be readily unscrewed and the packing either renewed or entirely removed, as may be found most convenient or desirable, this construction ot' the stem being also designed to obviate the necessity of packing. Another object in constructing the stem in this manner is to avoid placing the packing in too close proximity to the heated vaporizing-ehamber, as the great heat required to vaporize the duid is liable to char and render the packin g untit for the purpose designed, which is to control and regulate the flow of the iuid into the vaporiZing-chamber I.

c is a removable plug screwed into the upper part A of the stock, having a small tapering hole in its center, through which the vapor issues from chamber I/into the mixing-chamber B, where it is mixed with air. This removable plug provides a ready and cheap means ot' repairing the burner in case the orifice therein becomes enlarged, s3 that the end ot' the valve-rod Gr does not lill it perfectly. All ot' the upper portion ofthe burner-consisting of the mixing-chamber B, heating-chamber C, auxiliary burner E, and vaporizing-chamber* is similar to burners already in use, except that the heating-chamber C is formed as shown in Fig. 3, so that the llame that issues from the small hole near the bot-.tom of the auxiliary burner E will impinge upon the inward-curved surface of the heating-chamber and be delected back against the upper part A of the stock containing the vaporizing-chamber I, by which the latter will be more effectively heated, and thereby more rapidly vaporize the fluid contained in it. rlhe heating-chamber is attached to the upper part Al ot' the stock by means of a collar, D, that encircles it, thus rendering the slit in the burner H susceptible ot' being turned, so as t) present the broad side of the flame in any desired direction without the necessity of moving the lamp.

In connection with the several parts of the burner constructed and arranged as above described I emplo5v the Well-known regulatingand cut-ofi' valve-rod G, which I have arranged to stand in a vertical position under the mixingchamber B, so that the jet of vapor will ascend directly toward the center of the burner H and not mpinge upon the sides of the chamber, as is the case with some burners, whereby the ame is rendered clearer and more brilliant, and the tendency to smoke is avoided.
