Beit known that we, H NRY D. Huonns and EDWARD SIIALLOW, citizens of the United States, the said Ilnsnv D. Hoouns residing 5 at Radnor, Delaware county, Pennsylvania, and the said EDWARD SiuLtow residing at Philadelphia, inthe county of Philadelphia I and Statcof Pennsylvania,have inventeda certain new and useful Improvement in Hydro;

[O carbon-Burners; and we do hereby declare the following to hc'a. l'ull, clear, and exact description of the invention, such as will enable-others skilled in the art to which it appcrlains to make and use the same.

sumiug hydrocarbon oils in which ihe'oil is atomized or vaporized by means of a jet of steam or air made to pass immediately in front of the nozzle or dischargetip of the oiltube. The objects of our improvement are, first, to avoid the constant dripping of oil from the burner tip, so common in burners of this kind when constructed in the ordinary manner; second, to more thoroughly and easily 25 vaporize the oil and at the same time mingle therewith a sufficient quantity of air or steam, or both, so as to bring about a perfect combustion; third, to easily and correctly adjust the relative positions of the burner-tip and the 0 dischargenozzle for the steam o air; fourth, to supply the burner with such a'quantity of heated air that the pressure of the steam may be very materially reduced and the loud noise made by the rushing steam in a great measure 3 avoided.

In the accompanying drawings, Figure 1 is aside elevation of our improved burner. Fig. 2 is an end elevation. Figs. 3 and i are vertical sections of the nozzle or bur-neutip, show- 0 ing the construction thereof and the manner of connecting to the otherparts of the device. Fig. 5 is a section of a lime-kiln or other structure having one of our burners attached. A is an oil-tube communicating with the 5 oil-reservoir, which is'loeated some distance away and below the level of the outlet; to the burner. I

A is the head of the burner, secured vertically on the oil-tube at right angles thereto.

1/ is a nut or lnishiugscrewcd into the head d.

Our invention relates to burners for cona is a small tube t tling into the bushing (I, and surrounded with 'a packing, at:

a is a triangular slot in the tube a.

a is an arm fastened to the tube a, and carrying the end of the thumb-screw a This thumb-screw has a hearing, I), secured on the head A.

I) is the outlet'nozzle or burner-tip screwed into the lower end of the tube a. The rear end or inlet'orlfice of this burner-tip b is circular in shape, while the outlet or discharge opening is flat, as shown in the drawings.

B is a stcanrpipe, connected with any conv n'ient steam-generator.

C is a contracted nozzle screwed into-the ends of the pipes B and D. This nozzle is sccurely held in place by means of the jaln-nuta.

E is a hot-air tube secured to the tube. D,

' and connected with a heated coil or any other convenient means for heating the air before it passes into the pipe I). The nozzle Got the steam-pipe B is CXllclldOd into the tube D a short distance beyond *hepoint where thehotair inlet 0 is connected. (See Fig. 1.)

c is a bushing secured in the forward end of the tube D.

c is a small tube fitting into the bushing c, and surrounded by a suitable packing" to secure a tight joint. The tube 0' is similar in construction to the tube a; but it doc-s not have the triangular slot therein.

c is an extending arm on the tube c and carrying the thumb-screwtc; This thu1nbscrew has a stationary bearing, (1, secured to the body of the burner.

d is the outlet nozzle or discharge-tip for the hot air and steam. This nozzle or tip is identical in construction with the oil-nozzle ii on the end of the oiltubc, and has a'circular inlet and a flat outlet.

The position of the oil-nozzle b is adjusted up or down by means of the thumb-screw a",

and the nozzle (1 is moved back or forward by in 2a us of the screw 0. 'Th us a nice adjustment is obtained and the nozzles can readily and easily be put into the most advantageous P07 sitions. The tube a being provided with the triangular slot a, the supply of oil can be increased or diminished by simply screwing the tube a up or down. The inlet-orifice of the steam discharging from the nozzle (1'.

oil-nozzle I) being circular and the outlet flat,

when the oil is drawn through the natural cohesion of the particles is thereby broken up,

allowing the current of air or steam to more readily act upon it and reduce it to a vapor as ferent points the supply of each iseasil y regu- 1 lated, and when both are used together they are thoroughly colnmingled in the pipe D before being discharged through the outlet-nozzle. If

the steam is too damp, it is-brought to a suitieientideg'ree of dryness by increasing the flow of hot air. (lonsequentl y a very low pressure of steam may many times be maintained, As the head of the burner A is at right angles to the horizontal oil-supply tube, the burner-tip is in a vertical position and always placed over the nozzle of the discharge-orifice for the steam and air. This arrangement completely overcomes the natural tendcncy'of the oil to lique'fy and drip down off the burner-tip.

The burner being constructed and arranged as herein shown, the tube A is connected with an oil-tank located below the level of the burner, the steam-pipe B is connected with a steam-boiler, and the hot-air tube connected r'ith'a heated'coil of pipe located at any couvenicnt point. When desiring to use the burner, the steam is turned on through the pipe B, when it will be forced through the nozzle'G into the pipe D, creating a vacuum therein, and causing the heated air to rush in through the pipe E and mix with the escaping steam, when the eommingled air and steam are discharged from the flateopening of the discharge-tip (1 immediately below and in front of the nozzle or'tip on the endof the oil-tube, I

and by this means drawing or sucking theoil from :the reservoir through the tube A into the tube a, passing from thence into the burnertip I), being discharged therefrom through the flat orifice, when it is, immediately converted into a vapor, commingling with the air and In this condition it is ignited and. will readily burn,

We are aware that injector-burners have heretofore been made with oil-tubes having adjustable fiat tips, and that steam and hot-air tubes discharging through a single fiat orifice, which is adjustable, have been known, and we do not'claim such, as our invention difi'ers therefrom in the particulars which are specified in the following claims.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is-

' 1. The combination,'with the oil-pipe A,

having ahead, A, set at right angles thereto on one end thereof, a movable tip having a 6o tube or extension projecting into the head A and free tomove therein, and a screw for ad: justing said tip andextension in said head, of the tube D, having the steam and hot-air pipes connectcdand discharging into it, a tip having 6 5 a tube extending niovabl y into tube D, and a screw for adjusting the same, substantially as, set forth. I ,y

' 2. In a burner of the kind described, the

combination, with the oil-tube A, having the 75 head A, of the-tube a and tip b, said tube having the slits or openings a cut down from the upper end thereof, and an adj usting-screw for niovingsaid tube a, and the air and steam pipes having asingle discharge-orifice adjust 75 able therein, as set forth. 7

3i The combination, with he oilpipe or tube A, having head A and n adjustable tip therein, of the tube D, having the steam and hotairypipcs both discharging into it, the 'adj ustable bushing c, screwed into the end of tube 1), and the movable when, having tip (1 projccting into bushing 0,.and screw for adjusting the same, substantially as set forth.
