Specification of Letters Patent.
Jfatented March 6, 1906.
Application filed. April 20,1904. Serial No. 204,084.
To aZZ whom it may concern.-
Be it known thatl, ERWIN KRAMER,a subject of the King of Prussia, German Emperor, residing at N o. 9 Paul street, Berlin, Germany, have invented certain new and useful l'mprovements in Inverted Incandescent Gas- Burners, of which the following is a speoifica tion.
My invention relates to downwardly-directed or inverted gas-burners which carry the incandescent body or mantle at the lowest part of the mixing-tube.
The object of my invention is to provide an incandescent gas-burner the mixing-tube of which is considerably heated by the waste gases, so that the combustible mixture of gas and air downwardly conducted Within the burner isbrought to a high temperature before combustion in order to get a very high luminous efliciency while insuring the greatest economy. In order to attain these purposes, I provide on the free end of the burner-tube a contracted or narrow mouth or a mouthpiece having such mouth, which arrangement allows a combustible mixture which is rich in air to be conducted and heated to a high temerature in the mixing-tube without lighting hack of the flame: I prefer to arrange the mouthpiece detachably and changeably for regulating purposes. I further arrange a protecting-globe of glass or the like which surrounds the lower part of the burner-tube to such height that the hot waste gases are directed against and along the birrnentube, thereby heating the latter'.' For the purpose of further transmission of heat to the burner tube I arrange thereon a heating-plate, by which the combustion gases are led laterally above the edge of the globe. In order to revent the upper part of the burner-tube rom being cooled. through the atmosphere, 1 provide a mantle or jacket of hot air round the tube. This air-mantle is inclosed in a funnel-shaped casing-which, with its lower Wide end, abuts upon the upper face of the heating-plate, While its tipper narrow end extends to the head of the burner. Above the upper end of the funnel I place a cap which partially closes the opening at that end. Thus the mantle of hot air is in open communication with the atmosphere; but no circulation takes place. I further provide a washer of a substance whichis a non-conductor of heat above the head or suction chamber of the burner. This insulating-body avoids the transmission of heat to the luster to which the burner is fixed, whereby cooling of the burner would result and the luster would become blackened through the heat.
In the accompanying drawing, which forms a part of this specification, a burner adapted for carrying out these features of my invention is represented in a vertical section.
A nozzle a, formed in one piece with a nipple a, projects into a chamber b, which forms the head of the burner and is down-- wardly continued by a mixing-tube b. A number of perforations n are provided in the head I), through which openings air is sucked into the suction-chamber by the jet of gas issuing from the nozzle a and downwardly conducted within the tube 1), thereby mixing with the gas.
A mouthpiece g,having a contracted mouth 12, is screwed to the lower end of the tube 1) or dctachabl y fixed thereto by any other suitable means. The narrow opening it prevents the flame from lighting back to the nozzle (1, so that the tube 1) can be made of such a width that even with low gas-pressures an abundant quantity of air is drawn in for inducing complete combustion. Owing to the arrangement of a wide mixing-tube and its narrow mouth, the suction effect of the burner is scarcely altered when becoming heated, and a very intense flame with a blue-green core is produced under all conditions, so that with a small gas consumption and with a single step of air-suction the mantle is raised to a high degree of incandescence. With a given quan. tity and pressure of gas the flame can be ren- J the width of the opening h or by ap lying a mouthpiece with an opening of di' erent width. i
On a flange g of the mouthpiece g a ring Z, which carries the incandescent mantle f, is attached by means of a bayonet-jointfitting or the like allowing to fix or loosen the ring and the mantle, if desired.
ient form is fixed on the tube 1) by means of screw-threads or by brazing, soldering, or the like, so that transmission of heat from the plate to the tube can take place.
Three or more arms m, connected with the plate (I by riveting, brazing, or other suitable means, project downwardly and have screwed therethrough set-screws 1) near their lower extremity. The said screws engage beneath the upper flanged edge of a protectingglobe e, of glass OTtllQ like, thus supporting A plate d of circular or any other conven;
dered as intense as desired onl by altering the same at a certain distance below the. plate d. The globe e, which is provided at its lower end with one or more openings 0 for admission of air to the flame, surrounds the tower part oi the tube b to a certain height, so as to direct the hot products of eomhustion upward along the tube I), while tho-plate diconducts them laterally above the edge of the gio'oe'e. in this way the hot gases transmit their heat to. the tube 11 and to the plate d, so'that the mixture of gas and air is yery highly heated in the tube. Moreover,
this arrangement of the parts does not allow i Marge quantity of gas collecting in the globe, for which reason violent explhsion eannot arise on kindlingthe burner. in order to prevent the upper part of the tube I), whieh is not touched by the hot waste gases, from boing cooled, a mantle or jatltet of hot air is formed round the tut" by means of a hell, 'cup, or funnel shaped casing o, of metal, the lower wider end of at on is fastened upon the upper face of the heating-plate d, with its flange 0, by riveting, brazing, or the like, forming a tight joint with the same. The upper narrow end of the funnel (1 extends near the head (2. I prefer to make the l'un- .nel of such a term that it is not in contact. with the head 1), although the casing may be closed at that place. A rap 1' iueloses at a short distance the head I) and the upper end of the funnel 0,4;0 that although tho interior of the casing may be in open oommunit'ation with the atmosphere at that plat-o eiroulation and the entranee of fresh t-old airal'e oh- Viated. Owin to the close eontaot ol' the funnel 0 Witht to date II, a certain amount of heat is conducted from the latter to the funnel 0, which heats the air inelosod therein, thus producing a mantle of hot air round the tube b. The tunnel is preferably made of higidypolishcd metal whose. ooollirient of radiation of heat is smaller than that of metal not polished.
In the free end of the chamber I) a washer .or ring 1) of a suhstanec which is a non-eonductor of heat-such as steatite, poreolain, for exampleis fastened by eorrosponding screw-threads, and through a central perforation of the washer the nozzle i1. is screwed, so
as to project into the chamber 1). The arrangement oi' the ring i. presents the advantage that heat is not transmitted from the. burner to the luster to which the nipple g is fixed, whcreby,on the one, hand, the burner would inopportuneiy be cooled and,ou the other hand, the luster becomesblackened. lt not necessary that the joint of the washer on the nozzle and on the head should be gas tight, and therefore no packingis required. As the gas is not yet expanded in the cold pipe, the flash issuing from the nozzle possesses its ful r'uckin capacity and is able, therefore, to draw'in. a iiirgc u'antity of air. Under certainconditions the insulating part or a sec- I ond such may, however, he provided above the nozzle.
