HYDROGARBON-BUENER.

Specification of Letters Patent.

Application filed March 10, 1915. Serial No. 13,323.

residing at gan, have invented a certain new and useful Improvement in Hydrocarbon-Burners, and declare the following to be a full, clear,

, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, ence being had to the accompanying drawings, which form a part of this specification.

This invention relates to hydrocarbon burners and has for its object a burner nozzle adapted to effectively break up the fuel and mix it with theair.

A further object, it has a very simple means of changing the direction of ing gases.

Still a further object, it has a very simple air gate which may be easily maintained in any desired position of adjustment.

In the drawings,-Figure 1 is a side el evation of the complete burner. Fig. 2 is a top plan View. Fig. 3 is a view, partly 1 n section, of the air pipe, showing two pos tions of the air gate. Fig. 4: is a longitudinal section of the burner. Fig. 5 is a section on the line A A of Fig. 4. Fig. 6 is a detail of the fuel breaking device. which slips on to the end of the fuel nozzle.

This burner is intended for furnace use for melting scrap metal in crucibles, smelting, and in fact for any other purpose where heat is necessary for melting substances. The burner is so constructed that 'it will completely break up the fuel and do away with the necessity of a breaker block, which is very often located within the furnace structure itself. adapted to maintain a very low temperature when desired and may also maintain a very high temperature when this is desired. I do away with the breaker block by providing two pairs of fuel-breaking arms. The smaller pair is an integral extension ofthe The burner is very well referthe burn-v ring a which slips on to the end of the fuel nozzle 1;. Each arm is concaved on its inner side and the one arm is shorter than the other and curvesinto the concavity of the other arm. Hence, when the fuel issues from the nozzle 7), it strikes the concavity in the smaller arm and is thence deflected by the smaller arm into the concavity of the larger arm. This in turn deflects the fuel into the concavity of the smaller arm of the.

larger pair of arms p, whence it is deflected 1nto the concavity of the larger arm of the larger pair. The larger-pair of arms is removably fastened to the burner by the larger arm being bolted to the burner piping, and a supporting C-shaped arm 0 being bolted to the lower arm and supporting at its top the upper or smaller'arm of the pair which is bolted to it.

The air, which is blown air or compressed air, is. delivered through the air nozzle (5 whose orifice surroundsthe smaller pair of fuel breaking arms. It will be noticed that the fuel nozzle discharges in front of the orifice 'in'the air nozzle. This is important in securing the best results in aspiratmg the Patented Au 10, 1915.

fuel. These two pairs of fuel breaking arms,

will be noted that the orifice in the end of the nozzle d is an oval shaped orifice or what will be termed an eccentric opening. It will also be noticed by reference to Fig. i that the plane of the orifice is not perpendicular to the axis of the nozzle but tipped. Hence the walls of the nozzle on one side project farther than on the other. This arrangement is calculated to direct. the air blast'in a somewhat angular position with respect to the axis of the nozzle. Inasmuch as the air blast is the propelling medium for the fuel, the flame and the heated gases folloW the air blast. Consequently simply by turning the air nozzle d to bring this eccentric and tipped orifice into different positions, the direction of the flame and the heated gases may be altered so that when more heat is needed in somepart of the furnace, it may be secured simply by turning the air nozzle d. This may be done with the fingers as the nozzle is ordinarily located on the outside of the furnace wall and discharges into an opening in the furnace'wall (not shown). The air nozzle d is loosely threaded into its socket so that it may be easily turned.

In the air pipe c is located a rotatable air gate 7'' which is carried on a spindle g which isv half-way cut away in the portion that runs through the air pipe e. A bolt and nut secures the air gate to the halved portion of the spindle. A segment 7:. is screwed to the outside of the air pipe and over this swings a spring arm 2' provided with a point 7' which wipes the face of the segment along the segmental path described by the notches 70. This is the means for securing a step to step movement of the gate, and hence the gate remains in any position where the spring arm 71 is left, securing any degree of opening of the gate that is desired.

It is obvious that steam might be used in place of air to atomize the oil and hence when in describing the apparatus as adapted to handle air, I do not Wishto exclude the 7 equivalent steam.

What I claim is:

1. In a hydrocarbon burner, the combination of a fuel nozzle, an air nozzle about the fuel nozzle, and two pairs of fuel-breaking arms supported so as to project beyond the air and fuel nozzles and arranged so that the end of each fuel-breaking arm curves into the body of the next succeeding fuelbreaking arm, so as to deflect the fuel from one fuel-breaking arm to another directly in the path of the air blast.

2. In a hydrocarbon burner, the combination of a fuel nozzle, an air nozzle thereabout, and two pairs of fuel-breaking arms supported so as to project beyond the air and fuel nozzles, the smaller pair of arms consisting of one short concaved arm and one long concaved arm, the short concaved arm curving into the concavity of the long arm,

and the large pair of fuel-breaking arms having a short concaved arm into whichthe large concaved arm of the smaller air curves and a long fuel-breaking arm mto Which the short arm of the larger pair curves, substantially as described.

3. In a hydrocarbon burner, the combination of a fuel nozzle, an air nozzle thereabout, a pair of fuel-breaking arms, and? ring that fits upon the fuel nozzle and supports the said fuel-breaking arms, one of said fuel-breaking arms being shorter than the other and curving into the body of the longer fuel-breaking arm and itself curving into the path of the discharge from the fuel nozzle.

- 4. In a hydrocarbon burner, the combination of a fuel nozzle, and an air nozzle, having an oval opening, supported rotatably about the fuel nozzle for the purpose set forth. 1

- 5. In a hydrocarbon burner, the combination of a fuel nozzle, and an air nozzle having an oval and tipped orifice, said air nozzle being rotatablv supported about the fuel nozzle for'the purpose set forth. a

In testimony whereof, I sign this specification in the presence of two witnesses.

FREDRICK J. NICE.
