MEANS FOR OPERATING HYDROCARBON-BURNERS FOR METALLURGICAL FURNACES.

SPECIFICATION forming part of Letters Patent No. 757,606, dated April 19, 1904.

Application filed March 5, 1903.

in means for operating hydrocarbon-burners for metallurgical furnaces.

Certain types of metallurgical furnaces are supplied with oil fuel at opposite ends through the medium of oil-burners. The oil fuel is supplied in this class of furnaces first at one end and then at the other. Heretofore it has usually been necessary for two operators to stand at opposite ends of the furnace, so that when the operator at one end thrusts the burner at that end into the furnace the operator at the other end must withdraw the burner at said end. A third attendant has been required to be stationed at another point, so as to start the feeding of oil and air through the burner which is thrust inwardly and stop the feeding of the oil and air through the: burner which is adjusted outwardly. In case in the class of furnaces referred to only one attendant or operator is assigned for the work 5 of thrusting one burner in and the other out it is necessary for him' to first adjust one of the burners at one end and then walk to the 5 opposite end of the furnace for the purpose;

of adjusting the burner at that end. When the course first mentioned is pursued, it is obvious that the services of three men are required, while if the second course is pursued much time is lost by the attendant in walking from one end of the furnace to the other.

The primary object of my invention is toprovide a construction whereby one man at a given point can not only govern the adjusting inwardly of the burner at one end of the furnace and the adjusting outwardly of the burner at the opposite end of said furnace, or vice versa, but can also at the same time start the Serial No. 146,292. (No model flow of oil and air through the burner which is adjusted inwardly and stop the flow of oil and air through the burner which is adjusted outwardly.

A further object contemplated by the in vention is the provision of improved means for adjusting the burners so as to direct the discharge of oil and air'therefrom and onto the contents of the furnace at any desired angle. 1

With the above and other incidental objects in View the invention consists of the devices and parts or their equivalents, as hereinafter set forth.

In the accompanying drawings, Figure 1 is" an elevation of a metallurgical furnace, showing my improved hydrocarbon bu'rners in connection therewith. Fig. 2 is a view of the mechanism for operating the oil-burners and which is located in front of the furnace. Fig 3' is an enlarged detail View of one of the burners and means for supporting said burnerand permitting it to travel; and Fig. 4: is a detail view looking in front of the traveling roller, with the rails of the track in section.-

Referring to thedrawings, the numeral 5 indicates an ordinary form of metallurgical furnace. The openings forth'e int roduction of the hydrocarbon fuel are located, respectively, at opposite ends of the furnace, as most clearly shown in Fig. 1. Extending from opposite ends of the furnace at an incli nation are parallel rails 6 6, forming a track for the travel of a grooved roller or trolley '7. The inner ends of the rails of eachtrack are connected by a crossbar' 8, which crossbar is pivoted to a bracket 9, secured to the end of the furnace; The outer end of the track is suspended in any desirable manner, but is preferably hung on arod 10, depending from a ceiling, beam, or rafter 11 ilrsuch manner that the outer end of the track is raised, and hence -said track is on a gradual decline from its outer end inwardly The rod is preferably of two parts connected by a turn.- buckle 12, engaging right and left hand threads on the respective. sections of the rod. By turning this turnbuckle the-track may be erated by means of a suitable handle 45. Extending from one end of the horizontal pipe 43 and leading to the left-hand oil-burner is a pipe 46. Extending'from the opposite end of said horizontal pipe 43 and leading to the right-hand oil-burner is a pipe 47. The quantity of air flowing through the pipes 46 and i7 is controlled by means of valves 48 and 49, arranged in the respective pipes. In the operation of this mechanism for supplying the burners with oil and air if, for instance, the burners are in the position shown in Fig. I it is necessary under such adjustment of the burners to cut off the supply of oil and air to the right-hand burner and causea flow of oil and air through the left-hand burner. This is accomplished by turning the three-way valve in a direction to shut off the flow of oil through the pipe 38 and permitting said oil to flow through pipe 37, and consequently through the left-hand oil-burner. At the same time the'three-wtry valvecontrolling the airsupply is turned in a direction to permit the air to flow through pipe 46 and to shut off pipe 47. If now the adjustment of the burners is reversedthat is to say, the lefthand burner is adjusted outwardly andthe right-hand burner inwardlythe three-way valves of the respective oil and air supply pipes are turned in a direction to cut off pipe 3'7 and open up pipe 38, so as to allow the oil to flow to the. right-hand burner, and

to cut off air-pipe 46 and open up pipe 47, so as to permit the air to flow to said righthand burner.

From the foregoing description it will be.

seen that I provide a simple form of mechanism for obviating difiiculties which have heretofore existed in supplying the metallurgical furnaces with oil fuel and that by my improvements the oil-burners are readily regulated from one point and at the same time the supply of oil and air to the burners is also regulated at said point. I Furthermore, I provide a simple means for adjusting the burner at any angle so as to direct the oil and airdischarged therefrom onto the fire at the as particularly applicable to oil-burners and for use in connection with metallurgical furnaces, yet I do notwish to be understood as limiting myself thereto, inasmuch as the invention may be applicable to burners-for feeding any other kind of fuel and also adapted for use in other kinds of furnaces or heating devices. I also'do notwish to be understood as restricting myself to two burners lov cated adjacent to two openings of the furnace,
