VAPOR on. BURNER.

Application filedDecember 29, 1923. Serial No. 683,454.

I 0 all whom it may concern Be it known that I, JACOB BARTEL, a citizen of the United States, and a resident of Hillsboro, in the county of Marion and State of Kansas, have invented certain new and useful Improvements in Vapor Oil Burners, of which the following is a specification.

My present invention relates generally to oil burners and more particularly to vapor oil burners of a simple inexpensive type whose chief disadvantage arises from the fact that at low flame the vapor burns red and smoky due to the control of the fuel oil supply and the diminution of necessary pressure at the burner opening when this oil supply is retarded.

Burners of this type commonly employ elevated supply tanks for the fuel oil and the pressure of the gravity feed of the oil is necessary at all times if the burner is to produce the-same white, smokeless flame at all times during operation. It is the primary object to produce such a result, to provide for a more effective and efficient control with uniform results at both high and low flame and to bring about the desired result without complicating the construction of the burner or increasing the cost thereof.

In the accompanying drawing which illustrates my invention and forms a part of this specification,

Figure 1 is a side view with the valve controlling parts removed, and

Figure 2 is a vertical sectional view taken substantially on line 2-2 of Figure 1 showing the entire burner.

Referring now to these figures my invention contemplates a burner wherein generating and vapor rings 10 and 11 are disposed at right angles to one another and intercon nect in communicating relation at their upper central portions as at 12. These rings are of sufficiently different size so that the lower portion of the inner or vapor ring 11 passes through the generating ring 10.

The two rings 10 and 11 are disposed above a' starting pan 13 from the center of which a hollow upright 1 1 rises to the vapor ring 11 with which it communicates, the said vapor ring having a burner opening 15 in its median line and in line with the axis of the upright 14. The wall of this opening is tapered to coact with the upper needle valve 16 of a valve stem 17 depending axially through the upright 14 and having its lower portion depending through an internally threaded guide tube 18 below the pan 13.- The lower enlarged portion of stem 16 has threads 19, cooperating with the internal threads of tube 18 so that rotation of'the stem, applied for instance to its lower end which projects exteriorly through a packing nut or gland 20, serves to elevate or lower the needle valve 16 within the burner opening 15 and thus control the flame through its control of the amount of vapor passing through the burner opening without affecting the pressure behind the vapor.

As before stated, burners of the type to which my invention relates, employ elevated oil supply tanks and in the present instance such a tank (not shown) is in communication with the lower laterally deflected portion of the generating ring 10 through a supply pipe 21 and a hollow upright 22 which rises through the pan 18 and connects with the lower central portion of the generating ring, as particularly seen in F igure 2.

The upright 22 thus cooperates with up right 14: in supporting the rings 10 and 11 in properly spaced relation above the pan 13 so that quick starting is assured upon the burning of oil within the pan. Proper generation of vapor within the ring 10 in action is assured by a flame spreader 23 in the form of a plate swung by virtue of its aperture lug 24: upon a hook 25 depending from the connected upper portions of the rings 10 and 11.

For the convenient control of the needle valve 16, the lower end of its stem 17 may be universally jointed, as by means of a coil spring connection 26, to one end of a control rod 27 whose opposite end has a handle 28. Thus the control rod and handle may be turned to practically any angle to the valve stem so as to permit of convenient installation of the burner in various uses.

It is obvious that in action the gravity feed of the fuel oil or distillate is controlled by the back pressure of the generated vapor and that it creates a pressure on the vapor which is constant at all times during action so that uniform results are assured so far as a white, smokeless flame either high or low is concerned. By the construction and arrangement shown I am able to bring about this result without complicating the burner as a whole or adding to its cost.

I claim:

A. vapor oil burner including vapor and generating rings of hollow form disposed at approximately right angles and connected in communicating relation at their upper central portions, a fuel oil supply including a pipe and an upright connected to the lower laterally deflected portion of the generating ring, a starting pan through one side of which said upright extends, a hollow upright rising centrally from said pan, said vapor ring having its lower central portion connected in connnunicating relation to the upper end of the latter upright and having a burner opening opposite the axis of said upright, an internally threaded tube depending below the pan from said central upright, a needle valve within said burner opening having a stem depending through the said upright and said tube and provided with threads engaging the threads of the tube, and means engaging the lower end of said stern for rotating the same and adjusting the needle valve including a control rod having a handle at one end and a universally movable connection at its other end with the said valve stem.

JACOB BARTEL.
