:application filed March 2a, 1923. Serial No. 627,349.

To all lLaiton?, t may conce/m.'

lie it lrnown that l, Willman Ginori, a subject of the lling or' England, and a resident ci fpringiield, in the county ci Hampden and tltate oie Massachusetts, have inventeda useful Burner, ci which the s specilication. illy invention relates to improvements in devices or appiicancesi'cr burning gas tor heating purposes, and resides particularly in a hollow, slotted, burner head, to Which are and air inlets, and a hollow, slotted mixer or breaker supported in said head, both oi peculiar construction and combined in a novel manner, together with such other parte and .members as may be necessary or desirable in order to render the device complete and serviceable in every respect, all as hereinafter set forth.

ihe primary object ci' my invention is to produce a gas burner in which the gas and air are so thoroughly and completely broken up and mixed, before arriving at the place o combustion, that an intense blue tlame is produced such place, and suoli flame is normally projected a considerable distance from the burner, or is caused to spread over a large area when directed against a plate, crown-sheet, water-leg, or other resisting member located more or less closely to the burner, wherefore the latter is especially well adapted to use in steam-boilers and other heating apparatuses for houses and buildings.

Another object is to produce a burner of this character which is comparatively simple and inexpensive, yet strong and durable, consists of ew parts which are not liable to become disarranged or get out of order, and withal is highly eiicient and entirely prac ticable.

iVith this burner, due to the intensity and volume ot the dame produced thereby, a great economy in the consumption of the gas ifor heating purposes is eii'ected, and this is an exceedingly valuable feature of the invention.

The burner having the straight burner head can be used with practically equally goed results in either a vertical orhorizontal position, and the same may he true in some cases in regard to the burner having an annular burner head.

Other objects advantages will appear in the course ot the following description.

l attain the objects and secure the advantages ci my invention by the means illustrated in the accompanying drawings, in Which+ Figure l is a side elevation of a gas burner which embodies a practical form of my invention; Fig. 2, a central, vertical section through said burner; ld ig. 3, a top plan of the burner; Fig. 4, a central, vertical section through the upper part of the burner, taken at right-angles to the section in F ig. 2,' Fig. 5, a developed plan of the mixer or breaker; Fig. (l, a bottom plan of the burner; ig. 7, a top plan ci a inoditled form or' the burner; lig. 8, a central, vertical section through said modification, with parts broken away to economize space, and, Fig. 9, a develo ed plan of a breaker wherein there is a slight change in the length and arrangement of the slots therein.

Similar reference characters designate similar parts throughout the several views.

ln the embodiment of my invention, as illustrated in the iirst six views, the gas burner comprises a hollow member or tube l having a flaring base 2 and a slotted crosshead which forms what I term a burner head 3, a gas-inlet nipple i supported in said base by a cross-piece 5, a hollow, cylindrical, slotted mixer or breaker 6, and means to support the latter in said burner head, such means in the present example consisting of a pair of specially constructed screw-plugs 7. 7Ifhe tube l, base 2, burner head 3, and cross-piece may all be integral.

The nipple Il is tapped into the center of the cross-piece 5, with the axis of said nipple coinciding with the axis of the tube l. The nipple 4 is internally screw-threaded at the outer end for the attachment thereto of a tube or pipe which leads from the gas supply, and there are three, more or less, perforations 8 in the inner end of said nipple around a conical projection 9 that extends inwardly from the center ci said end. A cap l0 is provided for the inner end of the nipple Ll, and is in screw-threaded engagement therewith. ln they center of the cap 10 is an opening l1 into which the projection 9 extends. Gas entering the nipple ll, from the supply tube or pipe, passes through said nipple and the openings 8 into the cap 10, and out around the projection 9 through the opening 11 into the tube l. rihe projection 9 serves as a needle-valve by means of which "nfl and the cap 10 the amount of gas permitted to escape into the tube l is regulated. This means of controlling the ow of gas is old and well known, and any other suitable means might be 'substituted thereforo Air enters the tube l through the flaring base 2 around the nipple et and the cap 10 and on opposite sides of the cross-piece 5. The air and gas commingle in the tube l and pass through said tube into the interior of the burner head 3.

In the top of the burner head 3, when the device is positioned vertically, is a plurality of transverse slots 12. As shown in Fig. 4, the slots l2 are cut deeper on one side Athan on the other. The bottoms of the slots l2 on one side are approximately on the same horizontal plane with the axis of the burner head 3, while the bottoms of said slots on the other vside are above such plane. It has been found that combustion is improved by cutting the slots deeper on one side than on the other in the manner just explained. Combustion takes place as the mixture escapes through the slots 12, on the outside of the parts of the burner head 3 which form said slots, or rather the slotted portion of said head is enveloped by the flame which is projected therefrom a considerable distance, or caused to spread over a considerable area, provided the necessary structural conditions have been complied with and the parts and members properly adjusted.

Extending longitudinally through the center of the burner head 3 is a chamber into which the passage through the tube l opens, as clearly shown in Figs. 2 and a, and such chamber continues'through the ends of said head. This is the mixing chamber. The end portions of the head 3 are internally screw-threaded to receive the screwplugs 7. i

Each screw-plug 7 is interiorly recessed to receive one terminal of the breaker 6, and preferably the inne r-end portion of such plug is cut away above and below, as represented at 13-13 in Fig. Ll. Oppositel 1- disposed, arcuate projections or lingers id--lllare left on eachscrew-plug 7 at the inner end after cutting away the parts at 13, which fingers receive between them and assist in supporting one terminal of the` breaker 6, without obstructing materially the adjacent slots in said breaker, which slots are indicated by the numerals l5 and i521. The lingers lll are screw-threaded cx-V te iorly, like the body portion of the screwplug 7, for engagement with the screwthreaded part at either end of the head `When properly positioned the screw-plug 7 is aranged so that the fingers 14 are disposed crosswise of the head 3. In addition to the lingers lli, the screw-plug has an annular recess therein for the reception of raedeee one extreme end portion of the breaker 6 in which there are no slots l5 or 15a. The support afforded by the aforesaid recess might be sufficient without the fingers 14, onthe one hand, or the fingers lll might be sufficient without said first-named support, von the other hand.

lnasmuch as the breaker 6 becomes hot, the screw-plugs 7 should be screwed inwardly only so far as to a-ord the necessary support for said breaker and at the same time provide for the necessary expansion thereof. ln other words, there should be a loose lit between the breaker' and each screw-plug. The ser; 2h' breaker with its axis coinciding with the axis of the mixing chamber in the .burner head 3.

The slots l5 and l5 are laterally arranged, longitudinally of the breaker 6, in staggered or offset relationship in said breaker. The slots l5 are shorter than the slots 15, and all are arranged in rows circuniferent'ially and longitudinally of the breaker 6, with any intermediate slot 15a extending lengthwise in either direction between two adjacent slots l5, and any intermediate slot l5 extending in either direction between two adjacent slots 15. lt follows.y therefore, that any two slots longitudinally are in staggered or offset relationship, or alternately arranged relatively. rlhe breaker slots may or may not all be of the same length, and the distance which one slot extends in each direction lengthwise between the two slots on each side in each of the two adjacent rows, in a breaker of a given size may vary, as illustrated Very clearly in Figs. 5 and 9. In the Fig. 5 arrangement, the amount of extension of a slot between the slots on each side in adjacent rows is greater, and the distance between the ends of slots in the same row circumferentially is consequently less, than in the Fig. 9 arrangement, wherein the ends of the slots 15b in adjacent rows longitudinally of the breaker are comparatively close together, and the distance between the ends of the slots in the same row circiunferentially of said breaker is necessarily and correspondingly greater. A breaker having therein slots arranged as in Fig. y9 should be so placed in the burner head 3 that one of the portions of said breaker in which are included adjacent and alternately-arranged end portions of the slots is uppermost in said head, rather than one of the portions wherein is included onlyl a single row of slots, in order to obtain the best results, because in the first. instance ythe maximum area of slots is present at both the. top and bottom of the breaker, and the passage through the latter of the mixture and the delivery of the same at the place of combustion areenhanced or facilitated. In

lll() dll ineens@ the other arrangement less care need be exercised in positioning the breaker in the burner head.

ln practice, the gas and air which enter the base, inner end, or mouth of the tube 1, at 2, pass through said tube into the mi` chamber in the burner head 3, wherein the combined gas and air encounter the breaker 6 and pass upwardly or outwardly around and through the

slots

15 and 15a into and out of said breaker, with the result that, by the time the mixture arrives atthe slots 12 in said head, the constituent elements of said mixture are so completely broken up and commingled as to burn when ignited at the place of combustion, with a iervency and force that are very intense and quite superior for heating purposes.

The breaker 6 can be taken out upon removing either of the screw-plugs 7, and a new breaker inserted in place of the old, should occasion require.

rllhe burner illustrated ink Figs. 7 and 8 consists of a tube 16 having a flaring base 17 and provided with a cross-piece 18 in which is seated a nipple 19 that is provided with a cap 20, all similar to corresponding parts in the other burner, except that they are larger in the second than in the first burner. Mounted on orfintegral with the tube 16 is a cupped member 21 upon which is an annular, slotted member22, the two together forming a circularl burner head with a mixing chamber therein. The

members

21 and 22 are provided with exterior, coinciding, radial lugs 23 which are adapted to be secured together by means of screws 2l, said screws passing downwardly through the upper lugs 23 into screw-threaded engagement with the lower lugs 23. At 25 are represented lateral slots cut in the top of the member 22. The slots 25 are arranged around the entire circumference of the round burner head, being cut in the member 22 in substantially the same manner as the slots 12 are cut in the burner head 3. 'lhe ends of each slot 25 may be on the same horizontal plane, as shown in Fig. 8, or one end may be higher than the other, as in the iirst ein ample. The member 22 is cupped in the center, as shown at 26, to assist in forming a suitable receptacle for a circular breaker 27.

The breaker 27 is mounted in the round burner head in the annular space below the slots 25, of which space mention has just been made, and between the part 26 and the outer or rim portions of the

members

21 and 22, the horizontal plane in which is located the annular center of said breaker being on a level with the plane wherein is located the junction between said members. The breaker 26 has slots 15 therein, which slots correspond generally with the

slots

15 and 15a, but might be like the slots 15".

Any suitable means may be provided for supporting the breaker 27 in the diametrical center ol the annular space provided for its reception, such as three, more or less, lugs 28 rising from the member 21 beneath said breaker, and a corresponding number of crosspieees 29 above said lugs, said breaker being received on said lugs beneath said cross-pieces- Each cross-piece 2d extends between the part 2G and the outer rim or the member 22, and has arcuate part to engage the breaker.

lt will bevnoted that the burner head slots are, in each case, considerably wider and larger generally than the breaker slots, but that the la 3 are more numerous. These relative diderenees are essential to the success of the invention.

'lhe operation of the round burner is substantially the same as or very similar to that of the burner with the straight b ier head, only in the case or the round burner annular llame produced.

More or less change in 'the shape, size, cons struction, et some or all of the arts of my gas burner, in addition to those hereinbelore specilically pointed out, may be made without departing from the spirit or my invention, or exceeding the scope of what is claimed.
