VAPORBBURNING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 621,966, dated March 28, 1899.

Application filed November 5, 1898. Serial No. 695,589. (No model.)

To @ZZ whom it may concern.-

Beit known that I, ARTHUR KIrsoN, a subject of the Queen of Great Britain, and a resident of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements inVapor-Burning Apparatus, of which the following is a specification.

My invention relates to vapor-'burning apparatus, and is especially designed to produce a simple and effective apparatus for-producing the initial heating necessary to start said apparatus into action. ln all forms of such apparatus that I have heretofore designedsuch, for instance, as that illustrated in my United States Patent No. 600,7 92,dated March 15, 1898-the action is self-sustaining afteronce put in operation by reason of the fact that the heat given off by the burner is employed in part to heat the vaporizing-tube, and thus transform fluid hydrocarbon into vapor; but inl order to produce the initial heating of said tube some extraneous source of heat is necessary. To accomplish this in a safe and convenient manner, I propose to employ anvauxiliary electrical heater.

The apparatus'l herein illustrated and described is a modification of that shown in my Patent No. 613,685, dated November 8, 1898, and also an improvement on that shown in my pending application, Serial No. 681,594, filed May 24, 1898. The employment of the entire vaporizing-tube as a heating-conductor, as shown in said patent, requires a large amount of current. The locating of the electrical vaporizing apparatus in the vaporizing-tube itself, as shown in my application, Serial No. 681,594, interferes with the introduction of the improved form of vaporizing-tube filler, which I have found desirable, one form of Which is illustrated and described in my pending application, Serial No. 689,657, filed August 27, 1898. To avoid both these difculties, I propose to locate the electrical heatingcoil in a second and separate vaporizing-chamber, which shall have a suitable dischargeorifice for discharging-a jet of the vapor so that the issuing jet when ignited will heat 4said vaporizing-tube to the necessary temperature to start the lamp.

The preferred form of apparatus for carryingout my invention is illustrated in' the accompanying two sheets of drawings, in Which- Figure 1 is a side view, partly broken away and partly in section, showing my invention applied to what is known as a cluster lamp. Fig. 2 is a similar View showing my invention applied to a single-mantle lamp, the Vaporizer being located in the lower part of the lamp-burner. Fig. 3 is an enlarged detail View of the vaporizer, shown in section. Fig. 4 is an enlarged detail showing the sprayingnozzle in cross-section. v

Throughout the drawings like referenceii'gures refer to like parts.

l represents a vapor-burning lamp of any one of the general types illustrated and described in my patent, and applications above referred to.

2 is the vaporizing-tube, and 3 is the Vaporburner, Within the heating-zone of which the vaporizing-tube 2 is located.

4: is a mixing-tube supplying a mixture of vapor and air to the burner, and 5 is the oilsupply pipe.

6 represents the second vaporizing-chamber, Which has the discharge-orifice 7 and an inlet in the shape of a spraying-nozzle 8. 'This spraying-nozzle may be of any desired form; but I have illustrated one having the tWo op'- posing discharge-orifices 9 9, so that the tWo jets of oil are opposed to one another and produce a spraying action somewhat similar to that `ofthe old-fashioned fish-tail gas-burner.

10 is a branch oil-supply pipe controlled by the valve 11 and leading from the main supply-pipe 5 to the spraying-nozzle 8.

12 represents a high-resistance electrical conductor, preferably arranged in the shape of a conical coil, as shown.

13 represents a'battery or any other source of electric-current supply, from which current ows through the conductors 18 19 to the two ends of the coil 12. As a convenient arrangement I have shown one end of the coil attached to the metal-work of the lamp, so that one of the lead-wires, as 1S, should be connected to the metal-work of the lamp, or the same maybe grounded, in which case the corresponding pole of the battery will be grounded.

11 is any convenient form of air-mixing device, consisting, as shown, of a cylindrical hood surroundingthevaporiziiig-chamberand within which hood the said vaporizing-chamber is supported by spider-arms 15 15, die.

17 represents a retieulated diaphragm, of ire-gauze or similar material, located across the air-mixing device and in the path of the mixed air and vapor, which will be driven along by the jet of vapor issuing from the discharge-orifice 7. The lower end of the electrical coil is insulated from the metal parts of the apparatus by being mounted in non-conducting lugs 2O 20, &c.

In Fig. 1 I have shown the electrical lighter or second vaporizing-chamber,with its accessories, mounted between two mantles of the double burner. In Fig. 2 it is shown located in the lower part of the main burner 3, in which case the gauze diaphragms of said burner take the place of the special reticulated diaphragm 17.

2l represents any form of electrical switch for opening and closing the circuit from the electrical source of supply to the heating-coil. The electrical vaporizer may be inserted beneath the burners in the construction shown in Fig. l, asindicated at 1G 1G in dotted lines in said figure. In this case the necessary air is supplied through the mixing-tube, as is the case in the construction shown in Fig. 2.

'lhe method of operating my invention is as followsyThe switch 21 being closed, the coil 12 becomes heated toa red or white heat. The valve 1l being opened, oil is sprayed on said coil by the spraying-nozzle S and immediately vaporized. The vapor issues under pressure through the discharge-orifice 7, forming a jet which entrains a quan t ity of air up through the air-mixing hood 14. The mixture passes through the reticulated diaphragm 17 and is then ignited by a match or other convenient means. rlhe blue llame thus created heats the vaporizing-tube 2. When the vaporizingtube has been raised to the necessary temperature, the valve 2 inthe main supply-pipe is opened, admitting oil to the Vaporizingtube 2, where it is vaporized, and the operation of the lamp then becomes self-supportingin the well-understood manner. The valve 11 is then closed and the switch 21 opened until it again becomes necessary-to light the lamp. In the arrangement shown in Fig. 2 the method of operation is the same, except that the jet from the vaporizing-chamber G draws in the necessary air through the mixingtube 4 and the mixture is discharged through and burned at the main burner 3.

The advantages of the invention are of course the doing away with the necessity of using alcohol or other volatile fluid for starting the lamp or the attachment to a gas-tixture, which is sometimes employed for this purpose. At the same time the attachment does not interfere with the regular working of the lamp, and in the construction shown in Fig. 2 and in dottedv lilies in Fig. 1 it f1ts into the lamp itself and is completely hidden.

Various changes could be made in the details of the apparatus disclosed without departing from the spirit and scope of my invention, so long as the general arrangement of parts shown in the drawings and the general principle of operation set out in the specitication are retained. Other forms of vaporizing-ehamber and heating-coil could be employed, and the coil might be mounted in the vaporiziug-chamber in a different manner. The electrical connections shown are merely illustrative, and other ways of bringing the current into the heating-coil might be substituted in practice. The particular form of spraying-nozzle might be changed and the location of the electrical vaporizing apparatus Varied, so long as it is kept below the vaporiZing-tube, so that the heat generated by igniting the vaporized oil will heat said tube.

Having therefore described my invention, what I claim as new, and desire to protect by Letters Patent, is-

1. In a -vapor-burning apparatus the combination of a vaporizing-chamber, an electrically-heated conductor in said chamber, and a spraying-nozzle for delivering oil into said chamber, substantially as described.

4. The combination with a vapor-burning apparatus having a vaporizing-tube located within the heating zone of the burner, of a second vaporizing-cham ber having a restricted discharge-orifice, and electrical means for vaporizing the oil in said second chamber, said second chamber being located beneath the vaporizing-'tube, together with an airmixing device arranged in operative relation to said discharge-orifice, substantially as described.
