GAS BURNER. I

Applicationfiled May 10,

To all whom it may concern:

Be it known that I, JEnoMnTnAvIs, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented new and useful Improvements in Gas Burners, of which the followin is a specification.

i y invention relates to gas burners for burning natural or artificial gas, and designed for use in heating furnaces, stoves, ranges, and in other situations.

An object of the invention is to provide a highly eificient burner of the character indicated with which complete combustion is obtained, which is of simple construction, inexpensive to manufacture, durable, reliable, compact and which may be readily assembled with any desired number of like units.

A feature of the invention consists in the provision of a burner which is entirely free from the back firing or'jumping of the flame back into the mixing chamber, which so frequently happens in burners in common use. In my burner there is no mixture of air with the gas before it issues, so that the jumping back of the flame is impossible. Moreover, the burner furnishes its own pilot flame and continues to burn until the supply of gas is completely cutoff,

thereby avoiding the danger of becoming extinguished when the gas ressure is low and allowing the gas to escape without burning.

Other objects of the invention and the precise nature thereof will appear hereinafter.

In the accompanying drawings, which illustrate a burner constructed in accordance with the principles of my invention,

Figure 1 is a plan view of the burner.

Figure 2 is an end elevation.

Figure 3 is a longitudinal sectional elevation at the line III-III on Figure 1, and a portion being broken away.

Figure 4 is a section at the line IV-JV' on Fig. 1. w

Figure 5 is a horizontal section of a portion of the expansion chamber, as indicated by the arrows V--V on .Figure 4.

Figure 6 is a diagrammatic view showing a group of burners.

Figure 7 is a similar View of a modified arrangement of i the burners.

The burner asherein' shown, comprises a hollow body A providing expansion 1922. Serial No. 559,745.

chamber in which the gas is heated and expanded before it issues for burning, and a baflie B. The body A is preferably cast in a single piece and forms the expansion chamber 10 which is substantially cylindrical and is provided at its under side with a number of hollow transverse arms or pockets 11. The gas is admitted to the burner through a pipe 12, and issues therefrom through small apertures 13 formed in the upper walls of the compartments 11.

The bafiie B comprises inclined baffle plates or walls 14 extending lengthwise of the burner, and integral ends 15. The baffie seats on arms 16 formed on the ends of the body A and which extend "laterally therefrom, the inclined walls 14 bearing against the inclined ends of said arms." The part A and B are locked together by the pipe 12 and by a plug 17 which closes the end of the expansion chamber.

In operation, the gas which enters the expansion chamber is highly heated and expanded before it issues from the apertures 13. The pencils of gas escaping from these apertures, strike the inclined baflie walls 14 and are thereby spread or dissipated and mixed with theair at or near the initial burning point. This burning point is so closely held to the expansion chamber that the latter is highly heated and the gas thereby raised to a high temperature before it issues. The flames thus produced on the opposite sidesof the expansion chamber, by the'natural upward movement of the heated column of air and gas ascending between the baffle walls and over the expansion chamber, form a rapidly rising column of hot flame which draws to itself an increasing amount of air which,

in the higher portions of the flame becomes intensely heated, thus furnishing the very best conditions for complete combustion.

The apertures 13 are quite small,'being of such size that under normal conditions of operation and withthe usual pressure of gas supplied for. heating and lighting purposes, the gas issues with great force. The apertures are outwardly inclined at such an angle that the pencils of gas strike the baffle walls 14 about on a level with, or a short distance above thecenter line of the expansion chamber. These pencils of gas striking the two bafile walls are spread out so as to intermingle and are defiected inwardly so that upwardly converging sheets of flame are produced, which fully unite at some distance above the can pansion chamber, in an intensely hot concentrated flame. The converging battle walls deflect and concentrate the burning gases, increase the upward draft and cause the flames to envelop a large portion of the expansion chamber which is thereby raised to a high temperature. The gas is thus heated and expanded before it issues.

Figure 6 shows a group of burners arranged for use in a heating furnace. A. numberof burners may be connected in tandem by means of pipe sections 20, so that a portion of the gas entering the first burn er, passes on to the other burner or burners connected in line therewith. This arrange ment of burners in series gives very satis factory results. Valves (1, Z) and 0 control the supply of gas to the several series oi burners. It will be seen that by opening one or. more of theseyalves, either two, three, four, five or seven burners may be broughtj into use, depending on the amount of hea-t required. The valves also serve to throttle or restrict the flow to any desired extent, so that either a stronger weak flame may be maintained. A valve cl controls the flow through the main pipe to the manifold 21 to which the several series of burners are connected.

In Figure 7, a different arrangement of burners .is shown. In this instance, any number of burners from one to five may evidently be used at one time. A great variety inthe arrangement and number of burners used in any group, may be resorted to. lilodifications inthe construction of the burner itself may also be resorted to within the spirit and scope of my inyention.
