HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 784,787, dated March 14:, 1905.

Application filed July 14, 1904. Serial No. 216.481.

To all whom, it nuty concern.-

Be it known that I, FREDERICK E. GROUT, a citizen of the United States, and a resident of Orange, county of Franklin, State of Massachusetts, have invented an Improvement in H ydrocarbon-Burners, of which the following description, in connection with the accompanying drawings, is a specification, like figures on the drawings representing like parts.

This invention relates to hydrocarbon-bu rners, and has been especially designed as a burner for automobiles, which burner can be used for either kerosene, gasolene, or any other similar fuel.

One feature of the invention relates to a novel construction by means of which the air is delivered to the flame in such a way as to get the best possible combustion; and another feature of the invention relates to novel means for controlling the supply of liquid fuel to the vaporizing-coil and the vaporized fuel to the burner-openings, whereby when the supply of liquid fuel to the vaporizing-coil is reduced to a minimum the vapor is delivered to a minimum number of burner-openings, the number being just sufficient to keep up steam in the boiler.

Other features of my invention will be more fully hereinafter described and then pointed out in the claims.

Figure 1 is a top plan view of my improved burner. Fig. 2 is a section on the line a, Fig. 1. Fig. 3 is a top plan view showing the vaporizing-coil removed. Fig. 4 is a section on the line y y, Fig. 1; and Fig. 5 is a section on the line a a, Fig. 3. Fig. 6 is asection on the line b b, Fig. 3; and Fig. '7 shows the leaking-valve.

The burner comprises a burner-plate 3, which forms the top of a vapor-chamber 4, into which chamber the vaporized fuel is delivered, as will be presently described. In this form of my burner the burner-plate 3 is cylindrical and is surrounded by a suitable flange 5, on which the boiler proper rests. The shape of the burner-plate and flange, however, may be varied without departing from the invention. Said burner-plate is provided with a plurality of corrugations which preferably extend parallel to each other, and in the ridge 7 of each corrugation are formed a plurality of burner-openings 6, preferably in the form of slits. The central rib 8 is shown as a larger size than the other ribs, and it has therein burner-openings 9 in the form of slits, which, it will be seen, are larger than the slits 6. Situated immediately beneath the rib 8 is a rotary member 10, which is tubular at one end, as at 11, and is journaled at said end in a bearing 12 in the flange 5 of the burner. At the other end said member 10 is provided with the neck 12, which extends through the flange 5 and is journaled therein, as shown. The end of the tubular portion 11 is open to the atmosphere, and standing in line therewith is a jet-nozzle or valve 1 1, through which the vaporized fuel is delivered into the tubular mcm-' ber 11, from which it passes to the vaporchamber 4.

15 designates a pipe leading to the source of fuel-supply. Said pipe leads into a vaporizing-coil 1'7 and is controlled by a suitable valve 16, which is of peculiar construction, as will be presently described. The vaporingcoil 17 stands directly over the burner-plate and has a portion 18 thereof extending along over the burner-openings 9 in the rib 8. I Said portion 18 extends to a coil 20, which coil is connected to the needle valve or nozzle 14. Said coil 20 is preferably inclosed in a casing 21 and is constructed to be heated either by a suitable torch or by a burner 22, which gets its supply from the pipe 15 by means of a connection 23. This particular arrangement of vaporizing-coil and torch forms no part of my present invention.

The valve 16 is what I call a "leakingvalvethat is, it is so constructed that the supply of oil to the pipe 17 can never be en tirely cut off. This result can be accomplished by providing the valve with a very small groove 24, (see Fig. 7,) so thatwhen the valve is closed onto its seat the liquid fuel can still leak past the same. The object of employing a minimum by closing of the valve 16 the amount of vapor delivered to the vapor-chamber 4 will be also reduced to a minimum, and ifsaid minimum quantity of vapor were allowed to distribute itself throughout the vapor-chamber 4L combustion would cease because of the excessive air which the vaporchamber would contain. In order to avoid this, I have provided means whereby the closing of the valve 16 and the consequent cutting down of the supply of liquid fuel to a minimum is accompanied by the cutting out of a sufiicient number of the burner-openings, so that combustion will be maintained. In this form of my invention this is accomplished by means of the rotary member 10, above re ferrcd to, which, it will be seen, is substantially semicylindrical throughout most of its length. The shape of the member 10 is such that when it is in a position shown in Figs. 2 and 4 it completely covers and closes the burner-openings 9, but when the position thereof is reversed it opens said burner-openings 9, but cuts oil communication between the tube 11 and the vapor-chamber 1, thus practically reducing the size of the vapor-chamber to the interior dimensions of the member 10. The member 10, which is in the nature of a valve, is constructed to be operated simultaneously with the valve 16, the connections between said two valves being such that when the valve 16 is fully open the valve 10 is in the position shown in Figs. 2 and at, while when said valve 16 is closed the valve 10 has been reversed. In this form of my invention I have provided the end of the stem 12 with a gear 26, meshing with a gear 27 on the stem 28 of the valve 16, so that the valve 10 is operated by the valve 16.

l Vhen the burner is in use for generating steam, the valves 16 and 10 are opened, as shown in Figs. 2 and 4t, and the liquid fuel on entering the vaporizing-coil becomes vaporized, and the vapor is thrown into and through the tube 11 and distributes itself throughout the vapor-chamber 4;, as usual. The burneropenings 9 are closed, so that the vapor is ignited at each of the smaller burner-openings 6. \Vhenever it is desired to cut down the amount of heat generated and to generate only suflicient heat to keep the steam up in the boiler when no steam is being usedas, for instance, when the automobile is at rest-the valve 16 is closed, this operation reversing the position of the valve 10 and closing communication between the inlet-tube 11 and the vaporchamber 4:. At the same time the burneropenings 9 are uncovered. l/V hen the parts are in this position, a minimum amount of liquid fuel is delivered to the vaporizing-coil, where it becomes vaporized, and is then delivered to the reduced vapor-chamber formed by the member 10, from whence it passes to the burner-openings 9 and is ignited. There will be, therefore, a minimum number of burneropenings at which combustion takes place, and the heat thus generated is just sufficient to keep the steam up in the boiler.

For the purpose of supplying sufficient air to the flame to get good combustion I place in the grooves of the corrugations in the burner-plate 3 air-supplying pipes 29, which have slits or jet-openings 30 therein, through which the air is delivered. These air-pipes are so placed that the jet-openings 30 stand below the burner-openings 6, whereby the jets of air are delivered upwardly toward the burner-openings. This I regard quite important, because there is very much less danger of the flame being blown out by jets of air when thus delivered than when they are delivered either downwardly or horizontally. For supplying air to the pipes 10 I propose to employ the hood 33, which is illustrated as situated beneath the burner-chamber and as open at one end, as at 34, said open end when the burner is in use being directed forwardly or in the direction toward which the automobile is going. The back end 35 of said hood is shaped to partially inclose the flange 5, and the air-pipes 29 extend through the flange, and thus communicate at one end with the hood, as seen in Fig. 6. At the other end said pipes are preferably extended through the flange 5, as seen in Fig. 5, the pipes therefor being open to the air at both ends. The air is delivered through the jet-openings 30 partly by suction created by the upward movement of the products of combustion and partly by the forward movement of the vehicle and the consequent rush of air into the hood 38. From the above it will be seen that I have provided a burner in which the supply of liquid fuel to the vaporizing-coil and the number of burner-openings to which the vaporized fuel is delivered are controlled inde-. pendently, but simultaneously, and while I have shown one way of accomplishing this I do not wish to be limited to the construction shown, as the details of the device may be varied without departing from the invention.
