To all whom it may concern: 7

Be it known that I, ARTHUR E. HAUGK, a citizen of the United States, anda resident of the city of New York, county of Kings, and State of New York, have invented a new and useful Improvement in Heavy-Oil Burners, of which the following is a specification.

The object of my invention is to provide a device of this class which can burn to advantage the'cheaper grades of heavy oil, and make therefrom an intensely he. flame. This object is accomplished by my invention, one embodiment of which is hereinafter more particularly set forth.

For a more particular description of my invention, reference is to be had to the accompanying drawings, forming a part hereof, in which- Figure 1 is a side elevation of my improved burner and its connected parts.

Throughout the various views of the drawings, similar reference characters. designate similar parts.

My improved burner 1' is provided with an air' pipe 2 and an oil pipe 3 which are rigidly secured thereto and connected together by crossings 4. The pipe 3 runs to a valve 5 and the ipe 2 to a valve 6. The valve 6 is connecte by a hose 7 to the top of a tank through a T 9 at the top of the tank so that the interior of the tank 8 is subjected to an air or steam pressure, whatever it may the burner and y for air,

12 and the be,say. 125 pounds to the square inch. The :rneans for supplying air or steam to the T '9 is not shown, but it is preferably an ordinary hose connected to an air compressor or a boiler for steam, but may be any other suitable means. The top of the tank 8 also contains an air pressure gage 10 which indicates the pressure upon the in terior of this tank.

The valve 5 is connected to a. strainer 11 and the strainer is connected to a hose 12 which connects with a small valve 13 on the top of the tank 8, and this valve 13 is connected to a long pipe 14 which runs to the bottom of the tank 8. so that air pressure on top of the liquid 15 in the tank 8 will force the same up through the pipe 14, valve 13, tube 12, etc. For safety it is desirable to interpose a safety valve 16 between the hose valve 13. The safety valve is shown in detail in Figs. 8 to 11 inclusive, which consists of two valve casings 17 and 18, the former being the outflow casing and the latter the inflow. These two casings are secured to ether by screw threads, or any other suita 1e means, and are so shaped that they form a chamber between their ends. The casing 17 has screw threads 19 which are adapted to be secured to the hose 12 by a suitable coupling, and the casing 18 has also suitable threads 20 which are adapted to engage the valve 13 in the conventional manner. The outflow end of the casing 17 is screw-threaded to, receive a suitable perforated screw plug 21, in which is slidably mounted a plunger 22 which has a recessed stem so as to permit liquid to flow about the stem, and this is true of the other end. In its middle the stem carries a disk 23 which is adapted to rest either against the lugs 24 which project inwardly, as shown in Figs. 9 and'lO, from the w: lls ofthe casing 18, or a seat 25 at the end of the casing 17.

coil spring 26 normally rests between the disk 23 and the plug 21 and holds the disk 23 ed the seat 25 and against the lugs 21. Whenever there is an excessive flow of liquid under pressure by the disk 23, as can occur only when the hose 12 has become broken,

or some other accident has caused an extended leak,'in such an event such a rapid flow will close this valve by forcing the disk 23 on the seat 25 and thereby prevent oil from leaking out of the apparatus and getting on fire and causing trouble. At all other times the disk 23, under the action of the spring 26, remains as shown. By adjusting the plug 21, the tension of the spring 26 can be adjusted to correspond.

The top of the tank 8 carries a suitable funnel 27 by means of which it may be filled when convenient. This funnel 27 is screwthreaded at its bottom to receive the nipple 28 which is also screw-threaded and secured by screw-threads to the top of the tank 8. The nipple 28 is normally closed by a hollow plug 29 which has a flange underneath which is placed a gasket 30, and a wrench 31 is preferably fixed to the plug 29 so that by turning the wrench the plug may be removed or inserted, as desired. This plug not only serves for the purposes of stopping the hole,

but also as a vent because it can be opened.

before liquid is put in the funnel 27, and then any air pressure inside the tank 8 may be relieved before any oil is inserted. The oil is inserted by pouring the same into the funnel 27 and allowing it to run into the tank, and preferably through the holes in the bottom of the screw plug .29.

The burner has numerous parts which will now be described, beginning with the hinged cap-or flame directing nozzle 32 which is seen at the-extreme right of Figs. 1 and 2. This cap 32 has an upwardly extending ear 33 which is fixed thereon andis connected by a hinge 34' by which it is hingedly connected to the burner'tube 35, which is preferably made conical so as to fit the interior of the cap 32 and yet allow sufficient room for movement of the cap, as indicated by dotted lines in Fig. 1. The'ear- 33 on the cap is pivotally connected to a link 36 which slides in a bracket 37 fixed to the burner tube 35, and may be held in any suitable position by means of a suitable set screw 38. By this simplemeans the direction of the flame may be diverted, within limits, without shifting the axis of the burner 1.

The burner tube 35 has a slight taper as shown and suitable air receiving perforations 39 which admit any necessary air that may be required to perfect the combustion of the burner when the same is in use.

The rear end of the tube 35 is secured by suitable cap screws to the flanged plate 41 which is connected to the pipes 2 and 3, 'by means which will now be described. These pipes 2 and 3 are each provided with

large tubes

42 and 43 respectively which are closed at their forward ends which are beyond the holes 39 and well within the tube 35. As will be seen from Fig. 2, the pipes 2 and 3 project well into these tubes and beyond the holes 39. Near where these

tubes

42 and 43 join their respective pipes, they are provided with laterally extendin tubes '44 and 45 respectively, which are ent forwardly and parallel with the pipes 2 and 3', as shown, and end in a casting 46 to which they are secured. The interior of these

tubes

44 and 45 are connected to H-shap d passage ways 47 in the casting 46, one leg of which is closed by a screw 48, this screw being placed opposite the tube 45 so as to force the oil into the path of the air which issued from the tube 44.

The block 46 may be secured to the plate 41 by any suitable means, as a set screw 49, and it will be understood that the

tubes

42 and 43 also fit snug in suitable openings in the base 41. It is preferable to provide flanges about the casting 46 when the

tubes

42 and 43 extend laterally from the plate 41, although this may be modified if desired.

In view of the foregoing, the operation of my improved burner will be readily understood. Oil is inserted in the tank 8, as above described, while there is no pressure upon the interior of this tank in excess of atmospheric pressure, and when the oil is in place the wrench 31 is turned so as to put the plug 29 in position on the gasket 30, so as to in sure a tight joint which will stand a pressure of about 125 pounds to the square inch, or whatever is used, without leakage. Air or steam is then applied through the T 9 from an ordinary compressor or boiler, and

this puts pressure on top of'the oil, and

also permits air to flow through the tube 7 to the valve 6, and there it is somewhat reduced in pressure so as to make a slightly greater pressure in the tank -8 than in'the pipe 2. The difference is very slight and may be varied according to the nature of the flame to be produced. It will be noticed that this air, when air is employed, is ordinary compressed air, and as such contains moisture which, on-damp days, will be material. Oil flow is regulated by the valve 13 and solids are caught in the strainer 11 which must be emptied from time to time, as is.

obvious. The oil flow can further be regulated by the valve 5, should such regulation be desirable, and then the oil passes through the pipe 3 and into the tube 43 where it is pre-heated after the burner is once started. Air or steam passes from the tube 2 into the tube 42 where it is heated, after the burneris started, and any water or moisture that it may contain is then vaporized and changed into steam, and the commingled air .and steam pass together through-the pipe 44 where they act as an inspirator in the opening 47 to draw the oil and mix with the same, and these are ignited upon their emission from the hole 47, so that the burner will burn and it should burn with a very intense hot flame, which is suitable for all heating purposes for which such devices are ordinarily used. By closing the valves and 6 the fuel and air may be shut 011' the burner and then the flame goes out.

While I have shown and described one embodiment of my invention, it is obvious that it is not restricted thereto but is broad enough to cover .all structures that come within the scope of the annexed claims.
