Be it known that I, MONROE LEE Ross, a citizen of the French Republic, residing at 21 Rue Galilee, Paris, France, have invented certain new and useful Improvements in and Relating to Burners, (for which I have applied for patent in. Great Britain, No.- ,778, hearing date January 10,'1902,) of which the following is a specification.

This invention relates to burners, and particularly to burners for heating-stoves.

The invention has for its general object to provide a burner in which thereshall be the most intimate admixture of gas and air and the most perfect combustion in the flame.

According to the invention a burner is provided having two mixing-chambers, one within the other, thus constituting a double Bunsen arrangement, the outer mixing-chamber being provided with the top, insulated from the main body thereof. The top of the chamber is so provided as to form an annular space gradually restricted toward the top, this being effected, preferably, by the formation of the top of the mixin g-chamberas an inwardlyprotruding cone, a series of holes or tubes being provided upon the top of thechamber for the mixture of gas and air to issue in the flame, the arrangement being such that convection or circulation of the mixture of gas and air results at the top of the mixing-chamber before the mixture issues out through the holes or tubes, so that thereby firing or lighting back is prevented.

According to the invention also a circular hollow chamber-or radiator is provided above the flame, which chamber contains sand and lime, which is rendered incandescent and serves for the storage of heat, which" is uniformly radiated from it; but this hollow chamber may instead of being filled with sand and lime or other refractory material be formed of perforated plates, through the perforations on the top plate of which the flame may issue to produce a beautiful torchlight effect, the perforated plates in such a case being preferably lined with metallic gauze. The chamber or radiator may be formed of metal plates or of earthenware and may be used for the vpurpose of containing perfu min g, disinfecting, or antiseptic agents, which are diffused on the application of heat in the use of the burner. The plates forming the hollow chamber or radiator may be held together and may be fixed in any deter- 'mined position in relation to the burner by being carried upon a vertical pillar or stem, which is mounted upon the top of the mixing-cha mber, the pillar or stem being screwed throughout its length and carrying nuts by means of which the plates are supported and their position adjusted as required, or instead the mixing-chamber may carry a fixed plain stem, while the hollow chamber or radiator may be provided with a hollow central tube, by which the chamber may be applied upon the fixed stem without any necessity of screwing or manipulation and may be removed by simply being lifted off.

According to the invention also the casing or outer mixing-chamber may be provided in Y a number of parts or sections, the one capable of telescoping into the next beneath it, peripheral grooves and rims being, for example, provided near the terminal edges of the respective parts or sections,by means of which they may be sprung into position, so that when the casing is extended it may be retained extended until it is forcibly collapsed. Such a casing may be provided with its top surface formed of an inwardly-conical shape and may carry a circular hollow chamber or radiator, such as hereinbefore described, by

such means as a screwed pillar or stem, the

perforated plates or parts of the chamber being capable'of separation, while the collapsible parts or sections of the outer mixing-chamher when telescoped one within the other are capable of insertion within the plates or parts of the chamber for convenience of carriage or transport of the burner. ment of a collapsible mixing chamber may be provided with feet, which are so hinged as to be capable of being turned inwardly on the Such an arrange base part, while the burner is capable of being fixed in position in the base, part of the mixing-chamber by means of a cross bridgepiece fixed to the base part of the mixingchamber by such means as a bayonet-joint fastening, so that the burner may be withdrawn from the mixing-chamber for dismounting the burner or stove.

According to the invention a cylinder of gauze may be arranged centrally within the outer mixing-chamber, such cylinder dividing the mixing-chamber into a central space and an outer annular space, while a sheet of gauze may be transversely arranged within the mixing-chamber between the main body and the top part thereof, such cylinder and sheet of gauze serving for the purpose of the intimate admixture of the gas and air within the outer mixing-chamber and of preventing drafts or currents of air from affecting the perfect combustion in the flame.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a sectional elevation of a heating-stove provided accordingto theinvention. Fig. 2 is a sectional elevation on the line C D of Fig. 1. Fig. 2 is an elevation of the mixing-chamber and burnerillustrated in Fig. 1. Figs. 3 and 4 are respectively views of the respective plates forming the hollow chamber or radiator surmounting the burner as illustrated in Figs. 1 and 2. Fig. 5 is a sectional elevation on the line A B of Fig. 1. Fig. 6 is a detail view in section of a modified arrangement for mounting the hollow chamber or radiator over the burner. Fig. 7 is a sectional elevation of a modification in which the mixing-chamber is formed from collapsible parts or sections. Fig. Sis a sectional elevation corresponding to Fig. 7, showing the parts of the mixing-chamber collapsed and fitted within the plates or parts forming the hollow chamber or radiator.

In carryingthe invention into effect accordingto one modification, as illustrated in Figs. 1, 2, 2, 3, 4, and 5, I provide acasing 14, having its lower part 13 formed conical and outwardly flaring and with a supporting part 2, which part may be surmounted upon a foundation or base plate 1, provided with feet, as illustrated. The supporting part 2 is perforated with holes 3 for the admission of air, and this base part may, as is preferable, be formed separatelyfrom the main body of the casing 14, so that a greater or less amount of inlet for air may be provided, according to the heating capacity required of the burner, the supporting part 2 being provided with holes 3 of smaller or larger diameter or of smallerorlargerarea,according tothe amount of air required. At the base of the casing and carried upon the base part 1 a Bunsen burner 8 is provided, within which the gasinlet connection 4 is screwed, while a separate projecting nozzle 7 is screwed within this latter, as illustrated. This projecting nozzle 7 is made of soft metal, so that it may be pinched so as to be reduced or so that it may be enlarged, according to the quantity of gas required to be passed through, as determined by the heating capacity desired. The burner S is provided with lateral and opposite holes 9 and 10, respectively, through which air may pass from without, and a nozzle 11, prefer-.

ably of rose formation, is provided. The inlet-pipe connection 4 is screwed within a central hole provided in the base-plate 1 and is fixedly secured in position by means of a nut 6. The burner 8 is screwed upon the outwardly-protruding extremity of the inlet-pipe connection 4. The mixture of gas and'air which is more or less rich in gas issues outwardly from the Bunsen burner 8 and induces a further quantity of air into the easing 14 from below through the holes 3, whereby a further and intimate admixture of gas results with this new supply of air. The top 17 of the casing 14 is provided with an inwardly-protruding conical part 19, while a series of jet-holes 21 is provided on the base 20 of this conical part 19, so that the intimate mixture of gas and air from the second mixing-chamber may issue through. Anumber of rows or series of holes may be provided as required.- The formation of the top of the mixing-chamber as an inwardly-protruding cone allows of the convection or circulation of the gas and air in the upper partof the mixing-chamber prior to its issuing out through the holes 21, andthus precludes firing or lighting back. It is preferred to form the top 17 of the casing of the outer mixing-chamber separate from the main body 14 and to provide asbestos or other non-conducting washers or rings 15 or othermeans, so that thereby the heat from the top part may not be conducted to the lower main body part, and thereby effeet the expansion of the mixture of gas and air in the lower part of the mixing-chamber. The asbestos washers or rings 15 are preferably laid between flanges respectively provided upon themain body 14 and top 17 of the casing, respectively, and the flanges are secured together by such means as screws 18, as illustrated. The top of the mixingchamber carries a screwed rod or pillar 24, the lower extremity of which is screwed within a boss 26, provided within the inwardlyprotruding conical part 19 on the top of the casing, and upon this rod are mounted two curved parts or plates 22 23, preferably stamped from sheet metal, the top one 23 of which may be perforated and may be provided on its interior with a sheet of gauze. The peripheral edge of the one part 23 is engaged within that of the other 22, so as to form a hollow chamber or radiator, which may be filled with a mixture of sand and lime or with other refractory material or with any perfuming, disinfecting, or antiseptic substance, so that the chamber may thus be employed as a receptacle and radiator of heat and for the purpose of disseminating perfume, disinfectan t, or antiseptic. Nuts 27 28 are screwed upon the rod 24 and serve to set the position of the hollow chamber or radiator, as illustrated. It will be understood that the flame issuing from the top 17 of the casing heats the chamber or radiator above it to incandescence and maintains it at a certain temperature, whereby heat is uniformly radiated from it. The parts or plates 22 23 may each be perforated, so that gas may issue through the hollow chamber or radiator, so as to issue out through the perforations on the top part or plate, whereby a beautiful torch light effect is produced. In such a case it would be desirable to adjust the position of the hollow chamber or radiator in relation to the holes 21. A casing 31, provided with holes 32 toward its lower outwardly-flaring extremity, may be provided, and this outer casing may be provided with holes at its upper part and through its cover, so that currents of heated air may pass through.

In such an arrangement, as hereinbefore described, the use of sheets of metallic gauze is dispensed with; but with a View to rendering the flame uninfiuenced by any drafts or currents of air a cylinder of gauze 141 may be provided within the casing 14, which cylinder may rest upon the nozzle of the Bun-- or radiator may be provided with a central tube 242, as illustrated in Fig. 6, so that thereby for the fitting of the hollow chamber or radiator upon the burner it is onlynecessary 'to place the tube 242 upon the guiding-pin 241 and for removing it is only necessary to lift the chamber.

Instead of providing holes 21 in the top part of the casing or mixing-chamber tubes may be provided, especially where the burner is employed in connection with an incandescent mantle for lighting.

Instead of providing a vertically-disposed mixing-chamber this may be arranged horizontally, and the burner parts may issue outwardly from it, or instead the mixing-chamber may be formed as an annular chamber or may be disposed otherwise than vertical; but in such cases an intermediate mixingchamber may be provided, into which the Bunsen burner protrudes, While the mixture of gas and air passes upwardly at the opposite end of this chamber into the final mixingchamber, whence the jet or jets issue.

For convenience in the use of the burner with a gas-burner for lighting in rooms or apartments where only one gas-supply pipe is provided a three-way connection may be formed upon the fitting, which is screwed to the base of the Bunsen burner, to one of whose stems the gas-lamp may be connected.

In carrying the invention into effect in the provision of a burner or stove suitable for carriage or transport I may form the outer mixing-chamber from a seriesof telescopic parts or sections 35 36, as illustrated in Figs. 7 and 8, and in such a case these parts after being telescoped one within the other may be passed upon the rod or pillar 33, which in the cross-piece 81, having four arms which en-v gage within bayonet-slots provided in the lower part of the base portion 13 of the easing, while supporting-feet 211 are fitted to the base part 13 and are capable of being turned into a horizontal position when the stove is not in use.

The upper edge of each of the telescoping parts of the casing is preferably provided with an inwardly-protruding peripheral edge, which springs into the corresponding groove in the respective lower extremities of said parts, so that they may thus only be telescoped on the application of pressure in an axial direction. The parts, however, may be connected together when in their extended position by bayonet pins and slots or any other suitable means.

The main casing or mixing-chamber may be provided of earthenware or pottery instead of from metal, while the hollow chamber or radiator may be similarly provided from pottery or earthenware in two parts or in whole.

Instead of employing the burner for the purposes of a heating-stove the hollow chamber or radiator may be removed and a grid may be applied upon the top 17 of the casing, so that the burner may be used for other purposes, such as for cooking or for cooking liqnids.
