HYDROCARBON-BURN ER.

SFECIFIGA'IION forming part of Letters Patent No. 427,820, dated May 13, 1890. Application filed November 30, 18 88. Renewed November 11, 1889. Serial No! 829,833. (No model.)

To all whom it may concern.-

Be it known that I, JOHN ADAMS, of Nashville, in the county of Davidson and State of Tennessee, have invented a new and useful Improvement in Hydrocarbon Burners, of which the following is a specification.

My invention is in the nature of an improved hydrocarbon -burner designed especially for use in cooking-stoves and adapted to burn a mixture of petroleum or other liquid hydrocarbon and steam; and it consists in the peculiar construction and arrangement of the parts of the burner, as will be hereinafter fully described.

Figure 1 is a perspective view of a cookingstove with thefront part broken away to show my burner in the firebox. Fig. 2 is a top plan view of the burner removed from the stove. Fig. 3 is a vertical cross-section of the same, and Fig. at is a vertical longitudinal section through the steam-generator.

' In the drawings, 0 is an oil-reservoir, which is located a short distance above the burner and connects with it by a pipe a and a valve a. The pipe a is trapped between the reservoir and the burner by being carried down to near the floor from the reservoir, and then rises to the burner. The object of this is to keep a body of oil in the pipe a after the oil in the reservoir has been exhausted, and thus prevent the flames from striking back expldsively into the gases left in the reservoir.

W is the water-reservoir. This communicates with the steam generator H of the burner through pipe e, which enters the steam-generator at the bottom. This pipe 0 has a valve and also a trap e in the same.

The burner consists of two principal partsi. e., the oil volatilizing and mixing coils A B C D E F G, and a steam-generator H, arranged parallel therewith and side by side. The generator is constructed in the form of a fiat rectangular box, having a series of partitions f g h in the same, (see Fig. 4,) one series of which rise from the bottom and the other series of which depend from the top between the bottom partitions, forming, when water is admitted to the box, a series of trapped chambers, which prevent theback-pressure of steam from forcing its Way to the water-reservoir. About the middle line of the steam-generator there is inserted a gage-cock d, which is used to determine the water-level in the steam-generator. Inthe portion f of the generator the water is contained, in the part 9 the steam is generated, and in the part 71, which has no upper partitions, the steam is superheated, the jets of flame from the burner being so disposed or directed upon the box H as to secure this result. From the upper portion of the superheated steam chamber h there emerges the steam-pipe c, which carries steam to a valve Z), by which it is admitted to the tube A of the burner, a stem 1) projecting outside of the stove-casin g and provided with a hand-wheel for the operation of said valve. At the end of the steam-pipe c where it joins the valve 6 there is a pipe having a safetyvalve 0 and a drip-cock 0 The object of the safety-valve is to give relief to any excessive steampressure, while the drip-cock allows condensed steam to be blown out.

The upper tube A of the burner receives the oil from pipe 0, and valve a, and at the valve 1) also receives steam, which, becoming mixed with the oil, passes on to the elbows and tubes B O D E F G of the burner, in which the oil becomes volatilized.

The tubes G, E, and G are perforated with holes to allow the volatilized oil and steam to escape in jets, forming a gaseous mixture, which burns with an active combustion and intense heat. To the tube 0 there is hung a trough or pan I, which serves to hold a small quantity of oil which is poured in the same and ignited in starting the burner. This pan also serves to catch any drip of oil that may escape from the outlet-holes for the jets. The tubes 0, E, and G are each provided with perforations or j et-holes, through which the vapor under pressure issues and burns, the jets bein g so arranged in number and direction as to heat the burner-tubes,and thus volatilize the oil and also heat the steam-generator, and thus cause a sufficient generation and admixture-of steam.

In order that the function and value of the steam generator with partitions or baffleplates may be better understood, I will state that the series of hydraulic seals formed by the upper plates depending between the lower ones serve to prevent the back pressure through the feed pipe c, and this enables me to get a higher degree of heat and pressure IOO in the superheated steam, and this, by obviating its dampness and increasing its tension, promotes a more active combustion, free from all deposits of lamp-black. As the water in the partitions at f boils, the pressure of steam above forces the water-level down and throws the water and steam over into the chambers at g, which chambers complete the evaporation of the water, while the hot chamber it serves to thoroughly dry and superheat it.

Having thus described my invention, what I claim as new is- 1.. In a hydrocarbon-bnrner, the steam generating and superheating box having a series of partitions at the bottom and a second ries depending from the top between those of the lower series, in combination with a perforated burner-coil arranged beside the steam generating box, a valve connecting the steamgenerator and the burner-coil, and the oilsupply pipe, substantially as shown and described.

2. In a hydrocarbon-burner, the steam generating and superheating box having a series of partitions at the bottom and a second series depending from the top between those of the lower series, and a water-inlet and steamontlet, as described, in combination with the perforated burner-coils arranged beside the steam-generator, avalve conncctin g the steamoutlet with the burner-coil, the oil-supply pipe leading into the upper part of the burner-coil, and a trough located beneath the burner-coil, substantially as shown and described.
