of Kent and. Kingdom of England, have in--' vented a new and useful Improvement in- Vapor-Burners, (for which I-have obtained Letters Patent in Great Britain, No.' 16,636,

dated November 16, 1888; in France, No. 197,104, dated March 30, 1889, and in Bel gium, No. 85,619, dated March 30, 1889,)of

- which the following is a specification.

This invention has for its object the improvement of that class of vapor-burners in which steam is combined with air and oil vapor.

In my apparatus the oil is supplied to a burner, which consists of the following parts: a pan for receiving the oil, above which is a cover of conical form, which radiates heat on the oil and leads the vapor. thus produced from the oil into a suitable 1102216. In the cover there are openings admitting air which" the pan when the level of the oil in the pan falls below the mouth of the passage, allowing a small quantity of air to enter the tank.

In order to produce steam I place a steamgenerator in the form of a pipe-coil, as hereinafter described, one end of which. is r ef-- erably connected to a tank containing water under pressure, and the other end terminates in an injector jet in the middle of an air-pas sage in the center of the burner-pan.

Steam generated in the coil issues through the jet and draws in a current of air, and

thus a mixed current of air, steam, and oil-' vapor is directed through the nozzle of the burner, producing an elongated flame and perfect combustion.

forcing air by means of man into the water-tank.

Instead of employing a water-tank hand-pump described, the coil can be connected to the ordinaryavater-supply, or where steam is available the coil can be directly supplied wi hit. j

. The invention will be bestunderstood by reference to the accompanying drawings, in wh-ich 1 v Figure 1 shows an application of the burner to illuminating purposes, and- Fig. 2 an en-' .60 Similar letters refer tosimilar parts through out the several views. 1 i

larged view or the burner proper.

In Fig. 2: r represents'th'epan for holding the body of hydrocarbon to be consumed, which is preferably in the form of a shallow cylindrical pan, as shown in the views.

, In the bottom of the pan is a passage P j'rri-E. .Luolenn LIGHT PATI NT OF FICn. q f 1 forthe admission of air governed by a ro'tating valve P The passage or opening P is preferably made in the form of a funnel ora truncated icon0id,' a s shown-in Fig. 2. The

valve is'preferably placed at the bottom, so

as to more readilypermit of regulation. The passage is made in a separate casting, 'as

,shown in Fig. 2,and attached in any conven ient manner. The-passagel terminates just above the leyelof the oil in the pan, which is kept constant in the manner hereinafter described. a

The steam is supplied to the burner by means of any convenient form of jet that will at O, th-ehinges forming a trunnion with a packed joint for a water-pipe VV', that ascends'from the bottomof a water-tank WV. The pipe Wv is continued to form convolution's W of the pipe-coil, in which steam is generated, and from the top of the coilapipe The water-pressure may be. obtained by.

W, governed by a screw-stop valve W, descends 'tfoithe' steam-jet S, placed in the cenas above ter. of the: assage P. Within the coil W is a casing ot 'o'onoidal form, perforated with center'of the burner, and to increase the draft" produced' by theair-pass'ages. In the side of "the water-tankW is fixed a hand-pump A for compressing airwhich occupies the upper part of the tank, giving pressure suflicientto force the water up to and through the coil W When a supply ofivater under pressureis available, the tank 7 and the handpump A may be dispensed with, the pipe W being simply connected with the water-main and 'withor without a suitable controllingvalve.

casing O and the. coil W Theheat radiatthe oil maintains the supply of oil vapor;

The air entering at C is also heated and steam is generated in the coil W and after the burner has been a short time in action a powerful elongated flame issues ,atGfi'avaih able'for illuminating or heatingpurposes.

The cover. .0, together with the casing Cficoil W,the, pipe W and steam-jet S, can at anytime" be turnedover' upon the hinge C to give accessto the interiorof. the-pan and easing.

In Fig.1, 0. represents the tank. containing the source of supply. It is placed upon the top ofthe water-tank \V in the manner indicated.

The level L of the oil in the pan Pis deter mined in the following manner: From the bottom of the oil-tank'O a passage 0, provided with a stop-cock 0 leads to the pan'P; but only the lower part of the month of this passage is open, as indicated at 0 When the level of the oil in the pan falls below that in the passage 0, air can enter'by a port 0 and find its way into the reservoir Q, allowingthe flow of a small quantity of oil to the an. The operation of the burner will be obvious from the foregoing description.

Referring now to the application of the bnrner to a lamp for illuminating purposes,

as shown in Fig. 1, the lamp is ignited through theopening C of the cover, and as soon as the coil W or other steam-generating device becomes snfiiciently heated, water is forced into it by giving a few pushes to the handle of the force-pump A. As soon as the steam is generated the handle of the valve W is turned and steam admitted to the burner, and

at the same time the air-port P is opened. "When the hydrocarbon in the pan begins to give off vapors, these vapors will become mingled with the steam and airy-and perfect combustion will ensue. As the operation continues, the steam will be generated immediately at the inlet end of the generator, and during its passage .therethrough will become heated-and will issue superheated at the jets. The amount 'ofair can be readily controlled by the valve P and to supply wa- The lower part of the flame heats the saryvto give an occasional push to the handle of the hand-pump. The absence of water in with, and it will be obvious that the various parts'of the burner, being perfectly simple, can be cheaply constructed, and readily replaced as they become worn out.
