Application ma. April-20, was. semi no. 633,500.

The present invention relates to gas burnuse in connection `with waterheating appaer's, and the object is to prqvide devices havratus, heaters, and stoves, for domestic use.v ingports through which the gas may pass, Inthe present construction the to surwhich burners are practically free from the face of the ring portion 1 is provided) with objectionable feature ofblowing out when. a seriesof openings or depressions 5, which en the gas is under, what might,v be termed a. openings or depressions at their inner high pressure. ends have an outwardly extending ledge 6. A further object of the invention isL/to Preferably these openings are circular and provide a burner of such construction that each of the openings is adapted' to receive it will not back-fire into the mixer. and retain an insert member 7. This insert 65 A further object of the invention is to promember ma be of any desired form within vide a burner to be used in situations where the limits o the construction which is about it is desired to protect the gas ports from to be described, but in the present instance it moisture due to condensation'. is made to be round. The member 7 is hol- Reference should be had to the` accomlow, having an inner chamber 8, and the. 7o

There is an opening through Athe-wall elevation of an insert member for use in a of the member 7 which is opposite to the burner; Fig. 6* is asectional elevation of a surface which is providedwith port holes, modified form of insert member; Fig. 7 is thisopening being indicated 'at l0, and is 8U. a sectional elevation of a modified form of of a diameter less than the diameter of the insert member; F ig.8 is a sectional elevachamber 8 so that the rear wall of the memtion of an insert member and a portion of ber 7 forms what might be termed aledge 11.-

a burner of modified construction. By reference to Fig. 6 it will be seen that Referring to the drawings, the burner the construction there shown of the member 85 shown in4 Fig. l is of the usual ring type in 7 is in certain respectssimilar to that conkwhich there is the ring body portion 1 with struction which has been previously dei a neck 2 and the mixing end 3, all of which scribed. The top surface, however, is fiat are hollow, and the mixing end 3 has a cenand is provided with the opening 7b.` There tral spider 4 with an opening through which is theinner chamber 7 c and the openingin 0n the gas supply pipe with its proper orifice the rear wall of the chamber which is indimay be extended. The usual practice m cated at 7 d, this openinor being of less diamburnersof this. type is tovfdrill'hcles in the eter than thesgreatest dlameter of thechamtop surface of the ring portion of the burnber. A

These openings which extend at the center thanY they are toward the outer through the top surface receive the full prescircumference. i p sure of the gas, (and it frequently happens There is an inner chamber 7h and there is that due to the 'pressure the gas blows itself an opening 7 in the rear wall which is of out, or inother words, the flame-is blown less diameter than the greatest diameter of 105 away from the top of the burner b'ecause of the chamber 7h.'

It is difficult to This form of insert has been found very control these matters. except by the use of effective, in fact, in many respects it gives some special re ulating mechanism which better results than the other forms 4of in` is too expensive or installation in homes for serts in that it seems to provide a'greater 11.0

mixed, and this mixture passes `The burner structure in which the insert is inserted is indicated at 7L and has a recess 7m which at the lower part thereof is provided with an inwardly extending flange 7 which has an opening 7o which is of less diameter than the diameter of the opening 7 The inner peripheral -edge of the insert rests upon the inwardly extendingflange 7,

and as will be noted, this flange A7n extendsbeyond the inner' wallofthe chamber 7k.

It will be seen that'in this ystructure the use of the flange 7 ture proper,

in the burner structhe same eii'ect, sofar as the chamber is concerned,'is'obtained with respect tothe showing in Fig 8 asis obtained pinge upon the iiange 18 and be deflected so;

with respect to the showing in Fig. 7

The insert members as before `stated are inserted in the openings which are formed in the-ring portion 1. and the gas whensupplied to the burner passesthrmgh the openings 9 in the inserts.

4Itis well a this character known fact that in burners of the gas in the burning receives what is known as primary air and second ary air, that is to say, at the mixer-there is a certainmmouirit of gas and air which` are burner and through the orifices of the burner, but when the gas and air.- mixture -before described is burning there is a certain amount of air which is takenv up from I less diameter than the amosphere at the time of burning. The.

present burner is no dierent in this respect 'than those which have been heretofore used. However, due tov the fact that the insert member 7 is hollow, and further, due to the fact that what may be termed the inlet opening vin the rear wall of the insert is of the chamber of the insert itself, thegas which enters the chamber of the insert is defiect/ed and its pressure somewhat reduced so hat the openings in the top near the edge of the insert, are relieved-from the high pressure,

and therefore when the .mixture of primary air and gas are ignited after passing` through the insert members, the auxiliary air which is sucked in to comlete the combustion, does not cause any lowing out due to the fact that the pressure of the gas which row of openings is diminished. -Y

It should be noted that the insert' members may be made having obtained where the vinof depressions '16 in through -the surface of the insert, which openings areV passes throughthe outside of any desired material, good f it was made of lava.

In Figs. 3 and 4 there is shown different form of burner larly intended for use in a vertical position. The burner'consists of a head portion'13 with a neck portion 14 of increasing diameter, and at one end is 'the mixer portion A15. The head member 13 is provided with a plurality the same manner as has before been described, and inieach'of these as the insert-7 which functions inprecisely the same way.. In vertical burners of this kind the condensation which may'drip from the coils of a water heater or any part of an apparatus in which such 'a slightly' ,which is particudepressions there is insertedI an insert such burners are used is liable to contact with the inserts and cause the fiame -to be extinguished. In order to protect these inserts the head portion-13 is providedwith anextending flange 18"V which extends slightly beyond the inserts so .that

the outer end of the flange is substantially in line with the lower portion of each insert 'so that condensation which may drip will imthat it-ywil1 not come iir contactwith Athe 'i I burner openings proper. Having described my invention, -I-claim 1.
