GAS BURNER AND MIXER.

Specication of Letters Patent.

Application led April 6,\1914=. Serial No. 829,974.

To all whom 'it may concern.'

Be it known that I, JOSEPH A. KLonB, a citizen of the United States, residing .at Piqua, in the county of Miami and State of Ohio, have invented certain new anduseful Improvements in GasBurners and Mixers, of which the following is a specification.

This invention relates in general to the subject of burners, and has particular reference to a novel design of thatltype which is especially adapted to burn gaseous mixtures.v i

The main object of the invention is to provide a novel and improved form of burner and mixer that is of simple and durable construction, whose arrangement of parts is such that a maximum heating effi- `controlling the mixture of gas and'air in A such a wayl as to' suit the various exacting conditions of service when installed in the different systems above mentioned.

With the above and other objects in view which will more readily appear as the nature of the invention is better understood,

the same'conssts in the novel construction,v

combination and arrangement of parts hereinafter more fullv described, illustrated and claimed.

The essential features of the invention involved in the peculiar construction of burner and mixer, and mode of adjustingthe same, are necessarily susceptible to modication without departing from the spirit or scope of the invention, but a preferred and practical embodiment of the improvements is,

Accordingly, thei simple4 p fullv appear.

correspdnding parts throughout the several igures of the drawings.

In carrying out the invention, the burner Vmay be utilized 1n any convenient or practical way 1n connection with hot air, hot wa-v ter, or steam systems, or for other heating j purposes with either artificial or natural gas as the fuel.

`With particular reference to the construction shown in the accompanying drawings, the numeral 1 designates a burner section, while the numeral 2 designates a mixing section, both of which are preferably of cylindrical form, having frusto-conical end portions which are joined together by' a coupling member 3.

The burner section 1is formed at its upper end with a flared mouth portion 4, and also with a gas receivin chamber 5, while the side wall thereof adjacent the rim 6 is preferably flared asindcated at 7. The mixing section. 2l is similar in Ldesign to the section 1, and has'formed therein a mixing chamber 8 while its tapering side wall 9 is formed with a plurality of' cored slots 10 which are adapted to receive therein' the radiallv projecting lugs 11 of a gas feeder Patented Mar. 23, 1915.

member designated in its entirety by the ceiving chamber 5 forms a cavity C, the purpose of which will hereinafter more The entire burner designated as an entirety by the reference character B may be adjusted vertically upon the gas feeder member 12 because' of the radially projecting i chamber 8, While the upper portion 3a which projects into the gas re-l lugs 11 being guided in the cored slots 10.

Therefore, it will be observed that the body 13 of the said member 12 which includes a tapped hexagonal boss 14 and a gas out let chamber 15, may be attached to a section of gas pipe in such a manner that the gas will be conveyed into the chamber 15 and thence into the mixing chamber 8 through a plurality oit escapev orices 16. '.l` he central portion of the gas feeder member 12 1s formed with upwardly projecting standard 17 which is provided with a screw threaded socket adapted to receive one end of a screw' threaded supporting rod 18 which extends upwardly tln'oughV `the coupling member 3 into the gas receiving chamber. rlFhe said rod 18 is also threaded at its upper end as ment on the rod 18, the rim portion 6 of the Y between the wall 22 and the'dared wall 7 section l is provided with a plurality of upvvardly projecting pins 25 which are so arranged that they contact with the dameI spreader under all service conditions thereby insuring the latter to maintain its nor-f` mal position.

From the *foregoing description, it is believed to be apparent that the quality oit aseous mixture may be -easily regulated by adjusting the gas feeder member 12 in the open end of the mixing section 2 so that the circular body 13 of said feeder member may be drawn nearer-.or farther away from the wall 9- ot the section so as to admit more or less air into the chamber 8 as each particular case may require.y

'llhe dame spreader 20 is adjustable on the rod 18 so that its wall 22 maybe drawn toward and from the flared side 7 to regulate the size of the passagefor the escape oit the gaseous mixture toA produce a small or large dame as desired, and in this connection.,.it will be noted that studs 2t enable the dame spreader to be adjusted by means of a poker or simiar tool while the dame is burning. Aside 'from the adjustment of the dame spreader to control the volume ot blame obtained by rotating it upon the rod 18 it can also be adjusted, that is, the space can Ybe varied `when the entire body B is adjustedupon the member 12, thus enabling the valve to be originally setl so that by slight future adjustments, many varying and exacting conditions ot service may be itully complied with.

' Vlin connection with the coupling tube 3,-

and its upper portion 3a which extends into the gas receiving chamber 5, it may be said that the same is of great practical value, This tube'vvhich in the arrangement shown constitutes a Venturi tube is especially embodied in this construction to prevent bach tire explosions. ll'hat is. to say, through exiaeagraa perirnent it has ben found that in tiringbaclr into the mixing chamber of a burner, the back fire or ignited mixture alwaysfollows the wall of the chamber in which it originates and is contained. rllherefore, it in the present construction the back fire starts at the mouth of the burner section l, the same will follow the walls of the chamber 5 and be prevented from entering the mixing chamber 8 by coming in contact with the upstanding upper portion 3a which will tend to reverse the direction of travel ot the back ire'and cause it to again pass out with the gases coming through the tube 3 from the chamber 8. 'll`he provision ot this type of coupling 3 which forms the cavity or pocket C lessens to almost a certainty the possibility of the burner flashing back or bach tiring into the mixing chamber'.

lln the construction shown in Fig. ll, the

parts are identical with those shown in lilig. 2 except for the tube extension 26 which takes the place of the tube 3 shown in Fig. 2. 'll`he construction embodied in this gure merely illustrates another use to which the invention may be put, using either the burner section l as disclosed in Fig. 2 or a burner section of differenttype.

With' reference to the particular form of mixing section 2 shown in both Figs. 2 and 4, it may be said that this shape of mixer produces an increased area for air supply, while the tapering down of the chamber at its outlet end tends to increase the velocity of the mixture to the burner. Another feature of this form of mixing section is that the number of gas outlet orifices 16 may be increased to suit the different service conditions while at the same time obtaining the best possible mixing of gas and air.

llrom the foregoing description it is thought that the many features and advantages of the present invention will be .readily apparent, and that the method ot assem bling and disassembling the same is obvious. lBy making the parts detachable and adjustable, the burner may be made to suit a wide variety ot conditions, thereby enhancing its commercial value.
