GAS OR VAPOR BURNER.

SPECIFICATION forming part of Letters Patent No. 533,594, dated February 5, 1895.

Application filed April 16, 189 Serial No. 507,628. (No model) To all whom it may concern: sired construction, but which is preferably Be it known that I, HENRY A. HOUSE, aciticomposed of a hollow reservoir into which a zen of the United States, and a resident of hydrocarbon liquid in regulated quantity is Bridgeport, in the county of Fairfield and introduced through the pipe B. 5 State of Connecticut, have invented certain The interior space of the generator is dinew and useful Improvements in Gas or Va- .vided by transverse webs or partitions C that per Burners, of which the following isa speci- "extend partially across the same and form a fication, reference being had to the drawings serpentine passage with an outlet at pipe D accompanying and forming a part of the through which the vaporized hydrocarbon is [0 same. conducted to the burner.

The main object of my improvement is to so Above and partially surrounding the anincrease the capacity of a single burner thatit nular chamber E is a mixing chamber H may have a much greater range of heating efwhich is provided with a series of openings feet and available, without waste of fuel or I around its base and which extends up into c the necessity of adjustment or attention for another chamber J also provided with openproducing any desired amount of heat within ings K round its base.

A further 5 of valves of difierent degrees of sensitiveness, provision for the admixture of atmospheric in thesense that they are differently weighted, air with the vapor or gas is made by holes L or restrained against movement by any simiat the bottom of the central space or bore of lar means, such as by springs, so that the the annular chamber E. pressure of the escaping gas may be controlled In the top of the chamber E are orifices M 40 not only by each valve acting independently which are normally closed by valves N N. but by the number of valves affected by the Said valves have attached to them stems 0 pressure of gas acting upon them. which extend vertically down through guide A burner of this description is illustrated webs P and perforations in the bottom of the in the accompanying drawings, in whichchamber E into the chamber F.

Sufficient gas finds its way around the valve stems into the chamber F to maintain a flame at the end of this tube, the amount of gas being regulated by a screw plug T provided with a slot. In the use of the burner a small quantity of aqueous vapor sometimes passes through the valve openings and by its sudden expansion under the intense heat, extinguishes the main flame. The pilot flame, however, from its position is not afiected and serves to relight the gas as soon as the disturbance has ceased.

The operation of the device is as follows: Liquid hydrocarbon in an amount proportioned to the steam power to be generated is admitted to the generator A and being vaporized therein, by heat applied thereto when necessary, passes to the burner. The pressure of this vapor will raise to a greater or less extent say, the lightest valve, and the escaping jet draws up through the holes in the mixing chamber H and the nozzle J sufficient atmospheric air to maintain a perfect combustion of the vapor. One valve may regulate the pressure necessary for producing say, from one to five horse power. If a higher power is required the quantity of oil is increased and the pressure of vapor in the burner proportionately raised. If a single valve were relied upon to regulate for this increased pressure, it would be found that the jet of escaping vapor would be too thin to draw up enough air for perfect combustion, but the increased pressure raises the two lightest valves so that the air is now drawn in by the combined effects of two jets. In this way by the use of a plurality of valves and the proper adjustment of the same, one burner may be used and perfect combustion maintained for any number of horse power.

A special advantage is secured by making, in this kind of burner, the chamber E in annular form with a central air passage through it, as it prevents eddying of the gases, and affords a means of supplying air to both sides of the jets.

It will be understood that such of the heat as is not absorbed by the generator is utilized for generating steam or any other purpose.

Having now described my invention, what I claim is v1. In an apparatus for burning a gas or vapor, the combination with a source of gas subject to variations of pressure, a chamber into which the gas or vapor is introduced and a mixing chamber into which the gas chamber opens through a series of orifices, of a plurality of weighted valvesnormally closing said orifices and adapted to be raised by the pressure of vapor or gas within the gas chamber, as set forth.

2. In a gas or vapor burner, the combination with a chamber into which gas or vapor is introduced having a plurality of independent and difierently weighted valves normally closing orifices for the escape of gas from the chamber and adapted to be raised by the pressure of gas or vapor within said chamber.

3. In a gas or vapor burner, the combination with a chamber into which gas or vapor is introduced, and a second chamber beneath the same, of one or more valves normally closing orifices for the escape of gas and weights contained inthe lower chamber and connected with the saidvalves, as set forth.

4. In an apparatus for burning a gas or vapor, the combination with a source of gas subject to variations of pressure, an annular chamber into which the gas or vapor is introduced and a mixing chamber into which the gas chamber opens through a circular series of orifices in the top of the gas chamber of a plurality of weighted valves normally closing said orifices and adapted tobe raised by the pressure of vapor or gas issuing through the orifices, as set forth.

5. The combination with the gas chamber E and the lower chamber F of one or more valves controlling orifices in the top of the gas chamber, stems 0 extending down into chamber F and weights of different sizes attached to said stems, as described.

6. The combination with the annular gas chamber E having a central air passage, and the lower chamber F of valves controlling orifices in the top of the annular chamber and weights contained in the chamber F and suspended from the valves by stems passing through the gas chamber into the chamber F, as set forth.

7. The combination with the annular gas chamber E having a central air passage and the lower chamber F of valves controlling orifices in the top of the annular chamber, weights contained in the chamber Fand suspended from the valves of stems passing through the gas chamber into the chamber F and a pilot burner in proximity to the valved controlled orifices supplied with gas from the lower chamber F, as set forth.
