HEATlNGhBURNER.

SPECIFICATION forming part of Letters Patent No. 671,574. dated April 19, 1901.

Application filed February 2l, 1900. Serial No. 6,014. (No modela) T0 all whom, it may concern.'

Be it known that I, LEVI J. WING, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Heating- Burners, of which the following is a specication.

My invention relates generally to heatingburners for hydrocarbon gases and more particularly to heating-burners to be used in connection with acetylene gas or gases produced from metallic carbide.

In utilizing acetylene-gas for heating purposes where the heating-dame is conned in an inclosed compartment, such as a atiron, I have observed that the ame upon being coniined in such compartment is immediately extinguished, notwithstandingl the fact that a copious supply of airis fed to the burner from the atmosphere and admixed with the gas prior to or at the point of its com-1 bustion. Heretofore in order to overcome this difficulty especial attention has been paid to the method of proportioning and admixing the gases with atmospheric air in order to obtain a uniform and perfect combustion. My device, on the other hand, can be fitted to any burner of the Bunsen type and does not depend entirely for its success upon the method in which the gases are admixed, but upon a regulating attachment for regulating the combustion of the particles, so as to render the said combustion more uniform and complete.

Accordingly one object of my invention is to produce a burnerin which the combustion of the gases will continue after the flame is confined in an inclosed compartment, such as a fiat-iron or the like.

A further object of my invention is to produce a heating-burner in which the combustion of the admixture of gas and air is made perfect and uniform-in other words, a device which will compensate for the non-uniformity ofthe iiow of the heating fluid through same by consumingall non-oxidized particles not consumed by the heating-flame, so as to render the combustion perfect, and also, should the How of the heating iiuid be interrupted so as to extinguish the flame, to reignite same, so that the combustion may continue upon the renewed flow of the fluid.

'Po this end my invention consists, broadly, in partially inclosing the burner proper with a heat-absorbing or heat-retaining device, forming an impact-shield for the gas, made of a material that will readily absorb and give off heat. Thisheat-retaining device has been found to enable the combustion of the gas to continue when the flame is confined in a closed compartment, for by providing the burner with this device the latter is heated to a state of incandescence, and thus tends to eect the union of oxygen with the gas more readily.

My invention also consists in the hereinafter-described combination of cooperative elements.

In the accompanying drawings I have shown my invention applied to a Bunsen burner and have also shown how the heatingburner may be used for the purpose of heating an iron; but it will of course be understood that it may be used in connection with other devices, such as blowpipes, brazingtools, or in connection with cooking-stoves, or wherever a high degree of heat is required.

' In the said drawings, Figure l is a sectional view of a device embodying my invention. Fig. 2 is a sectional view of a modified form of the burner-outlet. Fig. 3 is a sectional view showing my burner applied to the heating of an iron.

Like characters of reference indicate corresponding parts in the different views.

I shall describe a heating-burner embodying my invention, and afterward point out the novel features in the claims.

1 indicates a tube farmed with a compartment 2, communicating with the passage 3 in the branch tube 4. The tube l is open at one end, as at 5, but is provided with a partitionwall 6 at the other end, forming an additional chamber 7. From this chamber 7 extends a pipe 9 upto the end 5 of the tube l, while around the said end 5,which forms the burner, is fitted (in this instance) an ordinary elbow 8. The gas enters at G and passes up through the passage 3 into the compartment 2 and from thence to the end 5, where it is mingled with the air entering at Aand issuing through the opening adjacent to the burner of the pipe 9. Here the Huid is ignited, the flame impinging on the curved portion 8 of the elbow 8 and issuing through the opening 8b. Within a few minutes after the lighting of the iiame the elbow 8 will be heated to a red heat, and by reason of this any particles not consumed bythe flame will be instantly ignited upon comiugin contact with such heated portion, and the combustion will, as a consequence, be perfect, leaving no smut or soot. This elbow 8, which is heated to an incandescent glow, also serves the purpose of reigniting the issuing gas in case its iow should be interrupted momentarily so as to extinguish the flame, and further serves to deflect the heating-fiance, so that it may be concentrated at one point.w`

Instead of the elbow 8 (shown in Fig. 1) various other forms of heat-absorbin g devices may be employed-such as, for instance, the form shown in Fig. 2, which latter shows simply a T-joint. The fiame in this instance issues at both ends 11L and 1lb of the said T- joint, while the portion 11c acts as the impactshield. Should it be desired to have the flame issue at more than one or two points, variations may be used provided with the requisite number of openings or apertures. Y

In Fig. 3 I have shown my device applied to the heating of a flat-iron l2. This iron is hollow, but may otherwise be of any construction suitable for the purpose. The tube l, provided with a screw-cut bushing 12b, is inserted through a suitable opening 12a. The opening 8b is pointed downward, so as to direct the iiame on the bottom of the iron, leaving the top portion of same comparatively cool. Suitable iexible connections, such as by means of rubber tubes 132L and 13b, are made with a gas-reservoir and a tank containing compressed air. Previous to inserting the burner into the fiat-iron the former is lighted and the heat retaining device brought into a state of incandescence, when the combustion will continue after the confinement of the flame. This, of course, is but one instance of many in which this burner could be used, but it will serve to illustrate the practical usefulness ofthe invention in the arts where a high degree of heat is desired.

Having thus described my invention, wha I claim is I. The combination of a comparativelyclosed compartment,a heating-burner located therein provided with au impact-shield so situated as not to contact with the side walls of the said compartment, and suitable connections for said burner with a gas-supply and a source of compressed air, substantiallyas described.

2. The combination of a comparativelyclosed compartment, and a heating-burner located therein provided with an impactshield so situated as not to contact with the side walls of the said compartment and in such close proximity to the burneras to constitute part of same and adapted to aid continuously in the combustion of the gases, and adapted further to concentrate the issuing flame at vone or more predetermined points, substantially as described.

' 3,'The combination of a fiat-iron and a heating-burner located therein provided with an im pact-shield so situated as not to contact with the side walls of the said iron, whereby the said shield is heated to a state of incandescence by the issuing flame, substantially as described.

4. The combination of a flat-iron and a heating-burner located therein provided with an impact-shield so situated as not to contact 4with the side walls of the said iron, whereby the said shield is heated to a state of incandescence by theissuing tlame,and so arranged as to concentrate the issuing iiame on the bottom of the fiat iron, substantially as described.

Signed at New York, in the county of New York and State of New York, this 19th day7 of February, A. D. 1900.

LEVI J. WING.
