OIL-GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 508,312, dated November 7, 1893.

Application iiled March 18, 1893. Serial No. 466,746. (No model.)

To LZ'Z whom it may concern: l

s 13e 1t known that I, WILLIAM @.HEIsTER, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Oil-Gas Burners, offwhich the following is a speciiication, reference be- 1n ghadtherein to the accompanying drawings.

This invention relates to certain new and useful improvements in oil gas burners, adapted to be utilized in the consumption of hydrocarbon oils, whether heavy and crude, or light and refined and the several peculiarities of my invention,in point of construction, and 1n point of organization or arrangement, will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings, on which like reference letters indicate corresponding parts: Figure l, represents a side elevation of my Improved burner, with parts broken away and shown in section; its application to a stove with a horizontal fire box being indicated by the dotted lines; Fig. 2, an end View of the burner detached, showing the relative positions of its several parts; and Fig. 3, a side elevation with parts also broken away and indicated in section, the application being to a stove with a vertical tire box as indicated in dotted lines. i

The letter A designatesthe tire box of a stove of any approved style, say of the kind in which the tire box is horizontal, as in cook stoves, and sometimes in heating stoves.

Within the fire box is placed my burner, say by resting it on or attaching it to suitable supports B.

The letter C indicates .the burner proper, consisting of a perforated pipe, closedat one end and connected at the other with a shell D. At or near the end of the burner which enters the said shell, I provide a chamber E from which leads aYV passage F, theV same being formed in a bushing or plug G secured within the burner.

To the upper sideof the shell D I connect, either by a screw thread, or integrally, an elbow H, to the other end-of which is connectedv the vaporizing pipe, I, which extends along in the same direction as the burner proper,;

of the stove and the surroundings of the place require it, be placed about on alevel with the opening where the oil supply pipe enters the vaporizing pipe I. A contractedoriice M is preferred to forni communication between such pipe and the supply pipe. Referring again to the other end of the vaporizing pipe I it will be seen that near it, in the elbow H, in Fig. l, and directly connected to it in Fig. 3,I provide what I term my vaporizer O, the function of which is to collect so much of the oil as passes through the pipe I without being'vaporized, and there to hold it against iiowing into the burner, until it becomes thoroughly vaporized. Thus oil in liquid form is prevented from reaching the burner proper, except in the mere act of starting the burner, as will be hereinafter explained, and thus is avoided all of those objections to oil burners which arise from the carbonaceous deposit, dueto a charred condition of the solid residuum left after the volatile products have passed off, forming and accumulating in the burner proper. This vaporizer consists of an outer shell and an'inner elongated neck, leaving a chamber P between the shell and the neck, the latter having a passage Q. As seen in Fig. 1 the shell screws into the lower end of the elbow H as seen in Fig. 3 the shell screws onto the lower end, direct, of the vaporizing pipe I. yIn either case the neck extends considerably above the bottom of the chamber,

,and in either case the same function or funcsupplied with water by a cock-controlledwater pipe Z connecting with a water tank A or with the city water pipes, so that the water ICO will pass into the pipe X of the generator under more or less pressure. A reduced orifice B is preferred between the Water pipe and the generator. It is also preferred to more or less pack the generator, with fragments of asbestus, fire brick or other non-combustible material, the natural interstices between which will form passages for the water and steam. These fragments, becoming highly heated, form a large number of heating surfaces in contact with which the Water and steam are brought, and by which the water is broken up into small bodies, rendering its Vaporization or conversion into steam much more readily performed. As the steam passes from the generator X into the superheaters V and S it becomes highly superheated, rendering it very dry and very hot. In this state it reaches the nozzle R, bywhich itis directed intoithe chamber E and passage F, and thence into the burner, while the vaporizedoil or the oil vapors and intermixed air commingle with it in therchamber E, passage F and burner proper,- the intermixture and intermingling beingcompleted and very thorough by the time the perforations of the burner proper are,y reached. Thus I vaporize the oil, intermix the vapor, with air, and then intermix this mixture with steam, and so produce a fuel which gives an intense heat, is economical, and is practically free from solid matter, and devoid at the place of ignition of any capability of forming a deposit. It will also be seen that my burner will operate without the steam appliance, though the heat obtained is-not so great.

By referring to Fig. 3, it will be observed, first, Athat I have left olf the steam. appliances, and secondly, thatI have adapted the organizationrparticularly for heating stoves with. the` The vaporizing pipe usual vertical -re box. 1n; thisligure is shown at I in a vertical position, receiving air at its upper end, Where the oil supply pipe K enters it, the orifice M belnggata slight angle, so as to directtheoil against the side of the vaporizing pipe.

In'thedotted lines at I in Fig. 3, I have shown: the upperportion of the vaporizing` pipecarried 0E on a` horizontal, and out of oneiside of the stove, having an elbow J and the` oil supply pipe K, just as shown at J and K in Fig. I.

At the lower end of the pipe I; I screwor otherwise connect to it the vaporizer O, which is the same as the vaporizer in Fig. I, except that the outer shell, as before observed, eX- tends above the inner neck, and except that I prefer to make the outward flare at the lower end a little more pronounced. The operation of the burner in this figure is the same asin Fig. l, when the steam appliances are not used in the latter. In Fig. 3, so much of the oil as is not vaporized in the pipe I or I 1", is receivedl into the vaporizer O, and there fully vaporized.

In starting the burner the oil is turned on and allowed to ll the vaporizer and slowly iiow over the neck. In Fig. 3 itis ignited at the base of the vaporizer, but as soon as the vaporizer becomes hot enough, together with the vaporizingpipe, nothing but vapor passes out of the neck, being so drawn by the draft, and it burns around the base of the vaporizer, the flames licking upward and somewhat outward.

In'Fig. l the oil must be allowed to flow until the shell D and the burner C are filled, so that it will ooze out of the perforations, for the initial lighting. As this oil burns away, the generated heat begins the vaporizing process and soon only Vapor is being burned.

The entrance of the air into and through the pipes I and I is facilitated by the partial vacuum created by the steam issuing from the nozzle R, such vacuum being essentially created in the shell D in and about the nozzle.

Having thus fully described my invention, what I claim as new,- and desire to secure by Letters Patent, is-
