In this; mummy as; is :eqn-parent, lw dinwnsiuns of thi-e mixing fizmlbn R uw pl'ogfissivavly oonstslciod in .fiirooton away from the enizugmi portion 12. The closed und b1 is fashioned linden noah with u small, stud .5 adapted to from@ tionato in the mounting of the humm' conrzlaztion by oca-,npyng n suitile wol-5% in,

the end b with d the casing of the heater. Thetop b3 is proposc of c slight baffling member as wil be hereinafter explained.

In describing the construction of the burner heads C which are intended to be removably mounted in the openings b1", .the singular number will for reasons of siniplicity be adopted. Each burner head C is hollow and has its lower end of suchf'di-` amcter that it may be inserted inte an -cf the openings 111 as a close mechanica iit. The upper cud c*I of the burner head C is of enlarged diameter to form interiorll an annular ledge c, und the upper rim is ashloned with three 'equally spaced ears` e4. An arched or dome-shaped strip of wired gauze c5 is positioned upon the ledge c3. and extends withina short distance of the upper edge of the portion c2, as is clearly shown in Fig. 4. A cap c having slots csimilarl'y spaced as the ears c* is plucedupon the portion c* such that the ears t project upwardly through the slots cl'to be suitably upset and lthereby fixed relatively thereto. Intermcdiitely of the ears c portions of the annular edge of the cap c are bent upwardly to form lips c whereby burning orifices having the shape of segmental slots are provided. The center c of the ca o is indented suflieicntly to engage and y old in place the crown of the gauze c5.

A mixture of air and gas after passing through the 'inlet L encounters the bar b which assists in a measure to eflect a thorough mixture by causing an added swirling motion. The furthcrmost removed of the openings b1" is assured of an egress of combustible fuel in proper measure since the size of the mixing chamber therebeneath is rightly proportioned with consideration of the liow lof fue] in its direction. 1Were it not for. the bailiing bar b that burner head (lwhich is nearest the inlet b would not receive a supply of fuel of Sufiieient pressure and it is in part for the purpose of diverting thev incoming flow toward this par-V ticular' burner head that such bar is provided. The faeilit with which individual burner heads may e removed is a valuable commercial asset since it fpermits of a replacement in the event o damage to any one of them. The arrangement" of individual gauze partitions in each of the removable burner heads makes it possible not only to replace with a minimum 'of labor auze portions which have become defective,

ut limitg the requirement of gauze replacement to the comparatively small strip that has become damaged. The spccic construction of my inventive burner heads in combination with the arched gauze partitions therein is such as to effect still further a homogeneous mixture prior to ignition adjacent the lips es and above the gauze as a deterrent of puiiing.

The modification illustrated in Fig. 5 involves a mixing chamber constructed as an integral casting D and similarly ,of constricted dimension in a direction away from the inlet d', because of the upwardly converging bottom d* and conver ing sides d and d, The top da is in accor ance with this form fashioned with integral burner heads d having drilled holes d1".

rfi modification with which Figs. 6 and.

7 have to do involves a mixing chamber E of two component parts, which together forlna i chamber of similar dimensions throughout its length with the exception of a reduced inlet duct e. The under portion e of' the major portion of the chamber E is provided Vwith longitudinally extending lateral flanges c, across the entire length of which an elongated strip of gauze c* is placed.` The complementary or upper portion e of the chamber E is similarly provided with flan es e adapted to conform to andrest upon t e iianges e3. These flanges as well as the interposed gauze are fixed relatively to each other by means of screws c. Above the portion e5 is fashioned a plurality of alined bosses es having like sized bores e9 in which burner heads C are to, be seated. i

Figs. 8 and 9 illustrate a modification in which amixing chamber F is constructed :is a hollow tubular casting of uniform crosssectional arca throughout save for a reduced inlet f. The bottom f2 in view of what was stated in the preceding sent-ence is not beveled toward the top though the opposite end 3 is again closed as in the other forms.

Extcndln along the top are a plurality of bosses f4 aying openings f as shown in Fig. 9. Removably mounted upon each of the bosses f* so as to compress a circular piece of gauze f thereagainst as with screws f", passing through an annular fiange f* is a simplified burner head f having below a hollowd portion f1 in registi' with the openings f5. The tops of such urner heads are provided with a plurality of o rificos fn.
