The tube a has its lower centrally with a depending lug 13, which has portion screw-threaded internally to render a vertically-arranged screw-threaded hole 14, too 50 it capable of being screwed onto a gas-supengaged by the correspondingly threaded ply pipe. (Notshowm) The tubeaisformed shank of a screw h, which extends through end of the chimney-holder.

the top of the drumfand has its head abutting against the under side of the said top. The screw it consequently holds the head 9 down upon the drumf. An annular space is formed, therefore, around the lug 13, which chamber is in open relation around the upper end of the drum f with the space between the drum and the surrounding wall or walls of the mixing-chamber e.

The head g is provided with four upwardlydischarging and upwardly-projecting tubular projections or nozzles Z, having the passage-ways therethrough preferably round and in open relation with the space 70. The projections or nozzles Z are arranged, preferably, equidistant apart around and equidistant from the center of the head g.

The drumf is large enough at its upper end to extend in under the whole of all of the passage-ways extending through the projections or nozzles Z, and preferably a washer m, of fireproof material-such, for instance, as asbestosis interposed between the head of the screw it and the under or inner side'of the top of the drumf.

The tube 0 extends a suitable distance below the tube d, as already indicated, and has its lower end enlarged transversely, as at 15, and surrounding the gas-discharging nose or nozzle b. The external annular shoulder 16,

formed at the upper end of the lower en-' larged portion 15 of the tube 0, is perforated, preferably, so as to form several air-inlets 17, arranged at equal intervals around the said tube and discharging downwardly into the said portion 15 of the tube.

A chimney-holder r surrounds the tube d externally of the standards Sand is provided at its lower end with inwardly projecting arms 18, which are riveted or otherwise secured to the said standards, and suitably-applied braces t extend between the lower end of the casing of the chamber e and the lower A globe, glass, or chimney u is shown within the chimneyholder and surrounds the burner in the usual manner.

The chimney-holderrbearsamantle-holder 00, which is usually a rod or wire extending upwardly into the chimney, and the mantle 3 which is to be rendered incandescent, is sus pended from the upper end of the mantleholder and has its lower end embracing the upper end of'the casing of the chamber e.

In the operation of the burner the air which supplies the oxygen necessary to produce proper combustion passes into the lower end of-the tube 0, and the gas is discharged by the nozzle 22 into the said end of the tube a, and the gas is discharged by the nose or nozzle 1) into the lower end of the tube 0. The air which enters the tube 0 is largely supplied through the air-inlets l 7, and generally air also enters the said tube at its lower end. The air and the gas pass upwardly through and commiugle more or less within the tube a and are discharged by the latter upwardlyinto the drum f, wherein the gas and the air more thoroughly commingle, and the resulting combustible and inflammable mixture passes from within the drum through the numerous perforations in the top and sides of the drum into the space surrounding the drum and into the annular space It next above the drum; but all of the mixture discharged from the drum finds its wayinto the space 7e and is uniformly distributed bythe latter to the tubular projections or nozzles l, at the outer ends I of which the mixture upon ignition burns with perfect combustion. It will be observed also that the upward enlargement of the drum results in a compression of the mixture passing upwardly externally of the drum.

The endwise adjustability of the tube 0 enables the regulation of the distance between the air-inlets l7 and the gas-discharging nose or nozzle 5 and also the opening at the lower end of said tube around the said nose or nozzle, and it has been found that the volume of air supplied in advance of the gas-supply nozzle must be decreased or increased in order to obtain perfect combustion, according as the density of the atmosphere increases or decreases. The velocity of the flow of gas into the tube 0 is retarded by an increase in the density or supply of air in advance of the gas-supply orifice or passage-way. The importance therefore of the endwise adjustability of the tube 0 is obvious. Hence it will be observed that the tube 0 after it has been addensity is shifted endwise in therequired direction by properly manipulating the said tube when the atmosphere changes in density, and the required proportions of air and gas to produce the desired-combustion are readily obtainable by properly adjusting the tube 0 upon lighting the burner and observthe burner.

A bluish or a whitish flame can be produced at pleasure, and the arrangement of the parts are such that the air-supply cannot be reduced to such an extent as to result in the production of a flame that is not smokeless. In other words, the arrangement of parts is such that when the tube 0 is shifted into its lowermost position against the tube or. enough air will still be supplied through the air-inlets l7, and the proportions of air and gas will not be aifected to such an extent as to result in a smoky flame during the operation of the burner. It will be observed also that as the gassupply nozzle is surrounded by the tube 0 and the air-receiving openings of the said tube are arranged above and belowthe discharging end of the said nozzle a draft or current of air straight across the interior of the said tube at the said end of the said nozzle is rendered impossible. The lower enlarged portion 15 of the tube 0 forms, therefore, not only the receiving end of the said tube, but constitutes a guard which prevents the creation of such a draft or current without interfering justed as required for an atmosphere of givening the character of the flame issuing from It will be observed flames into the burner during the operation of the burner.
