Fig. 7isasect-ional viewot` a modiner side, and a projecting lip O extends forfieation of the collar J. ward from the top of the burner above the A is the steam-jacket or caseetube screwed beveled portion. A beveled valve P, made into one end of the steam-jacket or ease-fitto fit themouthot the burner-tip, is rigidlyseting B. This tube and fitting constitute a cured to arod Q, which extendsbacklhrough roo 5o single incasing tube and may be made in one the tube C to a valve-stem R, mounted at the piece, the only object in making them in separear of the fitting E. A head S is turned on the end of the valve-rod Q, and it fits into a socket in the end of the valve-stem R, and is Y secured therein by a collar-plug T, which lits around the rod Q and screws into the socket in the valve-stem.

The valve-stem Ris provided with suitable seat and packing boxing U V, and handwheel WV.

A cross-bar X, with an opening Y in it, is mounted upon the inside of the neck of the burner-tip to support the valve-rod Q.

The operation of the burner is as follows: The tipN is inserted into the fire-box through an opening in the front wall of the fu rn ace, the pipes H and I are connected with the boiler, and the pipe Gis connected with the oil reservoir or tank, each of such pipes being provided with suitable cut-off valves. Aire is built under the boiler, so as to raise a slight headA of steam, ten or fifteen pounds being sufficient. The valve P is then opened slightly by turning the wheel XV. Oil .is turned on through the pipe G and steam through the pipes H and I. The steam which passes into the tube A through the pipe I blows out through the holes -L in jets which impinge against the oblique walls of the chamber K, and are deected across the end of the tube C, and the steam then passes into the chamber Z in the burner-tip, and from thence out through the opening between the valve P and the mouth of the burner-tip N. The eifect of the defiected steam blowing` across the open end of the pipe C is to create a vacuum in such pipe and cause the air and oil to flow through the pipes F and G into and through the tube C. The steam which blows into the tube C through the pipe H increases the vacuum and the consequent flow of air and oil. As the oil flows along the tube in front of the mouth of the pipe H it is blown by the jet of steam into a vapor and is thoroughly intermingled with the steam and air, and then passes out through the mouth of the tube C, where it is further acted upon by the deflected steam from the chamber M. Thence it passes into the chamber Z, whence it passes out through the opening between the valve P and the mouth of the burner, where it ignites. The dame soon heats the burner-tip sufficiently to decompose the vapor as it comes into contact with the walls of the chamber Z under the pressure of the steam and its own expansion. This prepares the fuel for complete combustion, which will not occur unless the vapor is decomposed and gas formed, and this is most effectually accomplished in making gas from oil by bringing the vapor of the oil into Acontact under pressure with a red-hot surface. This is accomplished by means of the chamber Z in the burner-tip. The opening between the beveled edge of the valve P and the mouth of the burner, being at an angle with the line of the burner-tubes, causes the flame to spread out sidewise and downward, while the lip O at the top of the mouth of the tip prevents the iame from being projected upward against the boiler. The lower side-of the mouth of the burner-tip is slightly curved, so as to cause the lower portion ot' the flame to conform to the shape of the boiler,while the upperlip of the tip is straight. The heat of the steam around the inner tube Cassists in vaporizing the oil, in conjunction with the blast from the pipe H, and prepares it for decomposition when it reaches the chamber Z.

By means of this device the heaviest grades of petroleum oils can be burned, as the jet of steam from the pipe H will cause a free iow of oil, which otherwise would not pass through the pipe without considerable pressure, and as the oil, when it flows into the tube C, is

rimmediately sprayed and mingled with steam and air, being at the same time subjected to considerable heat and is afterward acted.-

upon by another blast of steam which is directed across the line of the blast of vaporized cil, thus thoroughly mingling therewith, the air, steam, and vaporized oil are perfectly mingled and are in good condition for being decomposed when brought into contact under pressure with the heated walls of the chamber Z, and the `gas, as it issues from the mouth of the tip,immediately ignites, and an intense iiame is produced, complete combustion taking place. Should any of the residnum which occurs in crude oils/cause a clogging of the valve, the valve may be thrown wide open, the oil turned off, and the steamjets turned on to their full capacity. This will blow out all residuum and cleanse the burner.

The ame may be readily and accurately regulated by opening or closing the valveP and regulating the flow of oil and steam.

The collar J may be made as showirin Fig. 7 dispensing with the chamber K and giving an oblique direction to the vents L, the chamber being employed simply because it is a convenient form of construction, which will give the oblique direction required to throw the jets across in front of the vaporizing and mingling tube C.

Ve are aware that hydrocarbon-burners have heretofore been constructed with an airlandoil-supply tube surrounded by a steampipe extending slightly beyond the end' of such tube and surrounded in turn by another pipe for steam or gas, or both, whereby IIO the steam from the steam-pipe immediately surrounding the oil-tube acts upon the oil immediately before it is blown out from thek end of such pipe, and whereby the oil, air, and steam are thenvacted upon by an addi-r tional jet of steambefore issuing from the burner, asr shown in the patent to Parsons, dated June 5, 1877, No. 191,546, and we lay no claim to such construction.

le are also vaware that a blast of air has heretofore been passed through a tube for the purpose of driving coaltar into the furnace, as shown in patent to Brooke and Vrght, No.167,873, dated September 21, 1875; also,

that hydrocarbon-burners which mingle oil, air, and steam have heretofore been provide d With a decoinposing-chamber, Where the vapor and oil come into contact under pressure with a red-hot surface, and we do not claim the saine as new; but We are not aware that any burner has ever heretofore been constructed in such a manner as to vaporize the oil and thoroughly mingle it With air and steam, as is the case in the extended tube C,

` and then subject the vapor thus formed and mingled to an additional jet of steam as it enters into the decomposing-chamber.

Now, having described our invention, what We claim as new, and desire to secure by Letters Patent, is-

1. A hydrocarbonburner consisting of a vaporizing and commingling tube closed at one end and provided with ingress-pipes near the closed end of the tube for air, oil, and steam, such steam-pipe opening at the bottom of the mingling-tube toward the open end thereof, an incasing tube encircling such vaporizng and mingling tube, leaving a chamber between the two and provided with an ingress-pipe for steam, such tubes being provided With openings at the front ends thereof for the egress of the steam and vapor and connected with a decomposing-chamber and burner-tip common to and combined with such tubes, all being in combination, as set forth.

2. The combination set forth of the steamjacket tube, the steam-jacket fitting secured thereon and provided with the centrally-perforated head, the central air, oil, and steam mixing tube, the steam-collar provided with the frustuln-shaped chamber and the jetholes, the laterally-flaring burner-ti p, the beveled valve fitted in the flaring ii'iouth of the tip, the valve-rod secured to the valve and extending through the mixing tube and screwing through the rear of the burner, the five-way itting, the air-supply pipe, the oilsupply pipe, the forwardly-directed mixingjet steam-pipe, and the steam-jacket supplypipe.,

vaporizing and mingling tube, air-pipe F, oilpipe G, and steam-pipe H, discharging into the said mingling-tube, the jet-tube surrounding the mingling-tube and having means for admitting steam thereto, the steam-vents K and the burner-tip N, and the valve P within the burner-tip, substantiallyas described.

4. In an oil-burner substantially such as described, in combination with a vaporizing apparatus, the burner-tip beveled at its mouth around the sides and bottom and provided with a movable valve iitted therein, substan tially as set forth, the top of such tip above the valve being straight and parallel with the line ot' the burner, and the under side curved, substantially as set forth, whereby the flame is caused to conform to the shape of the boiler.

5. In an oil-burner substantially such as described, and in combination with the vaporizing mechanism, the burner-tip N and movable valve P, the tip provided with the lip O and chamber Z and beveled around the inner edge of its inout-h and curved at the bottom, substantially as set forth.
