GAS-BURNER FOR HEATING AND INCANDESCENT GAS-LIGHTING.
SPECIFICATION forming part of Letters Patent No. 7 56,893, dated April 12, 1904. Application filed December 2, 190a. Seria1No.18 3,588. (N model.)
To all whom it may concern:
Be it known that I, VICTOR ALEXANDER RET- TICH, a subject of the King of Great Britain, and a resident of the borough of Manhattan, in the city, county, and State of New York, have invented certain new and useful Improvements in Gas-Burners for Heating and Incandescent Gas-Lighting, of which the following is a specification.
My invention relates to that class of burners known in the art as Bunsen burners, and has for its object the production of a burner which is capable of burning a mixture of air and artificial or natural illuminating-gas with an intense heat and with a flame that will raise a refractory substance, such as a mantle now in use in incandescent gas-lighting, to hyperincandescence.
Another object of my invention is to produce and air can be made that will more nearly approach perfect combustion than has been heretofore possible with burners of this class, thereby producing a much more intense heatingflame than it has been possible to produce heretofore with artificial or natural illuminating-gas.
Afurther object of my invention is to so construct a burner as to enable me to introduce a larger proportion of air into the gas before it reaches the ignition-point of the burner and to more thoroughly mix the air and gas than has been possible heretofore. 1
A further object of my invention is economy in the use of gas for heating and illuminating, in that it is possible with my improved device to produce with a smaller volume of gas a flame with a greater number of heat units or a light of greater candle-power per foot of gas consumed.
The accompanying drawings fully illustrate my invention and the best method now known to me of applying the same.
Figure 1 represents my improved form of burner, showing its method of attachment to an ordinary gas-bracket, together with mantle and chimney for protecting the same. Fig. 2
represents a sectional elevation showing one of the forms 1n whlch my burner may be constructed. Fig. 3 represents another form in which my invention may be embodied. Fig. 4 is a sectional plan view through line 2 2, Fig. 2. Fig. 5 is a modified form of the burner shown in Fig. 1.
In the drawings, A represents anipple which is screw-threaded and adapted to be attached to the ordinary gas-bracket and is provided with a small opening or jet-orifice A, through which the gas flows to the lower mixing-tube. Surrounding the jet-orifice and screw-threaded to the nipple A is the upwardly-converging mixing-tube B, which is provided with the airinlets B at its lower end and the air-inlets B at its upper end.
0 is a downwardly-diverging shell attached to the mixing-tube D above the air-inlets B and extends downward, surrounding the said the mixing-tube B and diverges upwardly andforms a secondary mixing-chamber in which to mix with the gas the air which flows inwardly through the air-inlets B It will be seen that the lower opening of the upper mixing-tube D is larger than the opening in the lower mixing-tube B near the air-inlets B The purpose of this is to allow the gas to expandas it flows out of the upper end of the mixing-tube B and enters the secondary mixing-tube D, and thereby more thoroughly mix with the air, raising it more nearly to the perfect combustion-point.
Where my improved burner isused for illuminating purposes, a gallery E is attached to the tube D and is adapted to support the chimney F.
The operation'of my improved gas-burner is as follows, it being assumed that the gas in the pipes is under the ordinary pressure: On opening the gas-cook the gas rushes upwardly through the jet-orifice A, creating a upwardly with considerable force into the mouth of the secondary mixing-tube D, which is larger than the opening in the lower mixingtube B and which discharge of gas and air in turn creates a vacuum in the lower end of said mixing-tube D, thereby drawing additional air inward through the air-inlets B The gas and air drawn in continuing upward expands, allowing it to be thoroughly mixed with the air before being discharged at the combustionpoint at the burner-head.
By surrounding the lower mixing-tube B with the outer shell G and carrying the lower end of same down for a considerable distance upon said mixing-tube B it causes my device to act as an inspirator and draw air upwardly in said shell C, through the air-inlets B into the upper mixing-tube D, preventing any outward escape of the gas.
My burner may be made without the shel C, as illustrated in Fig. 5.
In the modification shown in Fig. 2, A is a nipple screw-threaded, so as to be attached to the ordinary bracket of a gas-supply pipe. The nipple A is provided with a gas outlet or orifice A, through which the gas passes to the burner. B is an upwardly-extending and inwardly-tapering mixing-tube screw-threaded to the nipple A. G represents a shell which surrounds the upper portion of the tube B and is constructed in form as a double shell, its inner portion being tapering to fit and bear upon the outside of said mixing-tube B its lower end extending outwardly and attached to the outer portion of the shell at the lower outer edges in any suitable manner. The horizontal lower portion of the tube C is perforated withair-inlets, as B and may have spun upon it what is called an air-check B. The construction is more particularly illustrated in Fig. 4. To the upper end of the shell C is attached in suitable manner the upper mixing-tube D Fig. 3 illustrates another modification of my invention, wherein the lower mixing-tube B and the upper mixing-tube D are formed of a continuous piece of metal tapered upwardly and downwardly to their narrowest portion in the center. There is attached a shell corresponding to the shell C in Fig. 1. The upper end of the lower mixing-tube is provided with air-inlets B corresponding to the inlets B in Figs. 1, 2, and 5.
The various forms of construction illustrated in Figs. 1, 2, and 3 are similar in principle and mode of operation.
Having described my invention, what I claim is 1. In a gas-burner a lower mixing-tube having continuous upwardly and inwardly tapering walls; gas and air inlets near the lower end of said lower tapering mixing-tube; secondary air-inlets near the upper end of said lower mixing-tube; an upper mixing-tube having upwardly and outwardly tapering walls attached to the upper end of the lower mixingtube, said lower tapering mixing-tube extending a short distance into the lower end of the upper mixing-tube.

the other of said series of air-inlets being near the lower end of the upper mixing-tube; and a downwardly-diverging shell attached above the upper series of air-inlets.
5. A gas-burner comprising lower and upper tapering sections joined at their smallest diameters; air-inlets at the lower end of the lower section; air-inlets at the meeting-point of said lower and upper sections; and a shell, one end of which is joined at the meeting-point of said upper and lower sections, said shell tapering downwardly and outwardly and surrounding the lower portion of the burner.
6. A gas-burner having two mixing-chambers meeting midway the height of the burner, the lower mixing-chamber tapering upwardly, and the upper mixing-chamber tapering downwardly; an air-inlet near the lower end of the lower mixing-chamber, and an air-inlet near the meeting-point of both said mixing-chambers; and an outer shell surrounding and inclosing the second air-inlet and extending downwardly to a point near the first air-inlet.
7. In a gasburner, a lower upwardly-tapering portion; air-inlets near the lower end of said lower portion; air-inlets at the upper end of said inwardly-tapering portion; an upper outwardly tapering portion joined to said lower portion near the upper air-inlets; a shell joined to said'portions near their meetingpoints, said shell extending downwardly and flaring outwardly and adapted to surround and inclose the lower portion.
8. A gas-burner comprising upper and lower mixing-tubes; two series of air-inlets in the lower mixing-tube and a shell surrounding the lower mixing-tube and attached to same I above the upper air-inlets, its lower end being I open to admit air.
