3 Claims. (Cl. 158-2) This invention relates to improvements in adjustable mountings for liquid fuel burners of the character employed in open hearth furnaces and the like.

The invention has among its objects the provision of an improved and simplified adjustable burner mounting structure, simple to construct, maintain, and operate.

Additional objects and advantages will become apparent from the following description taken in connection with the accompanying drawings,

4 in which:

Figure 1 is a vertical section through a portion of an open hearth furnace showing a burner adjustably mounted therein by an embodinent of the invention;

Figure 2 is an enlarged plan View of the adjustable burner mounting of Figure 1;

` Figure 3 is a View in vertical section of the adjustable burner mounting, said section being taken along the line III-III of Figure 2; and

Figure 4 is a View in elevation of the burner mounting of the present invention with the burner removed, the view being taken in the direction toward the outside of the furnace.

Adjustable burner mountings such as disclosed in the patent to Lewis, No. 2,358,982, dated September 26, 1944, have proved to be disadvantageous in certain respects due to the fact that certain of the adjustable elements, such as the elongated screw for adjusting the burner laterally, being positioned close to the furnace Wall, are subjected to dirt and the intense heat from the furnace and become diicult to manipulate.

` It has further been found that such mounting requires considerable maintenance, and that even with such maintenance the horizontal adjustment of the burner is difiicult, often requiring the efiorts of several men. It is accordingly an object of the invention to provide a simple easily maintained mounting for burners of the type indicated, which provides for the easy adjustment of the burner, both angularly in a vertical plane and transversely of the furnace.

' Referring to the drawings, A designates an open hearth furnace containing a bath of molten metal B. The burner C for the combustion of liquid fuel, such as tar, is directed inwardly toward bath B from outside the furnace through an opening E in the end thereof, said burner including an elongated tube or pipe, the greater length of which is disposed inside the urnace away from external support.

The improved mounting of the present invention for suchburner is generally indicated at D,

Secured to the bucksta'ys 2 of the furnace which are' a part of the framework thereof; and which may be in the form of vertical I-beams. Secured to buckstays 2, on opposite sidesof the opening' E, is a horizontally disposed anglebeam 4 which forms a support forpthe burnermounting. See

cured to `angle beam 4 at the locations equally' spaced from the vertical center ofopening E are two vertical twisted bars 6 disposed as" shown with their upper fiat portions bolted in contact` with the rear of the beam 4 and with their lower parallel portions extending vertically benath. The lower ends of suchparallel portions of `twist-` long horizontal bottom portion parallel to sleeve ID Burner C is carried by a clamp whicl' consists` of a lower portion l4 and an'upper portion I&

which at least partially embrace the burner. and which are held thereagainst in clamped relation by means of bolts [8 extending through the con-` fronting ears 'of the upper and lower portions of the clamp. The upper portion |6 of the clamp is provided with a headed stud 20, projecting upwardly at right angles therefrom, stud 20 extending through sleeve 22 as shown. sleeve 22 in turn is welded to horizontal sleeve 24, the latt er sleeve being disposed about the lower hori-- zontal portion of U-shaped bar l2 so as to be slidable thereon. The means thus far described provides a support for the burner Whereby the latter may be moved laterally and may be moved angularly in a vertical plane. i

Additional means are provided to? secure the burner in the desired lateral or angular position and to permit the ready change. of either of such adjustments. Such additional means consists of a second clamp embracing the burner C sat a position to the rear of the first named clamp.

such second clam'p consists of two members `26 and 28, shaped at their intermediate portions so as substantially to conform to the burner tube,:

the upper portionsof parts 26 and 28 being loosely hinged together as by a tongue cn part 28. which projects througha hole in the upper end* of part 26. Bolt 30 through the lower projecting ears on hinged parts 26 and 28 holds such parts together. may be tightened against the burner tube to hold thelatter in the clamp. t g

A set screw 32 screwed into part 26 Angular adjustment of the burner in a vertical plane is accomplished by means of a turnbuckle 'connected between the rear burner engaging clamp consisting of parts 26 and 28 and the spacer tube !0. such turnbuckle consists of a threaded end 34 pivotally attached between the lower ends of portions 26 and 28 by means of pivot bolt 36, a ,second oppositely threaded end 38 welded to 'sleeve 40, which slides upon tube n, and a turnbuckle sleeve 42 engaging portions 34 and 38. It is obvious that by turning sleeve 42 of the turnbuckle, the vertical angular disposition of the burner tube about the axis consisting of the horizontal portion of U-shaped bar l2 may be changed.

Adjustment of the burner laterally is accomplished by means of a second turnbuckle attached between the rear burner tube engaging v clamp and a fixed portion of .the burner mounting means. Specifically, such means consists of a U- shaped bracket 44 welded to the left hand twisted bar 6 in Figure 4. One threaded end 46 of the second turnbuckle is Secured to bracket 44 by means of the vertical pivot pin 48, the eye portion of -member 46 through which pin 48 passes being sufliciently thinner than the opening between the arms of the U-shaped bracket as to allow substantial freedom of movement of part 46 in a vertical direction. A second U-shaped bracket 50 is welded, ,as shown in Figures 2 and 3, to portion 28 of the second clamp at a position substantially in line with the axis of the burner C. The opposed arms of U-shaped bracket 50 extend vertically, as shown in Figure 2, and project substantially in a direction toward pivot pin 48 when the burner tube is directed at substantially right angles to the end wall of the furnace. The threaded end 52` of the second turnbuckle is connected to bracket 50 by means of horizontal pivot pin 54. Parts 46 and 52 of the second turnbuckle are connected by threaded sleeve 56, the turning of which pulls said parts together I or pushes them apart, depending upon the directionof rotation of the sleeve. Sleeves 40 and 24 travel upon means lil` and l2, respectively, and thus allow the burner mounting and the burner carried thereby to travel laterally upon adjustment of the second turnbuckle. fIn the modification shown the second turnbuckle lies in a plane which is substantially at right angles to the plane containing guides l2 and I 0.

It will be apparent from the above disclosure that the adjustable burner mounting means permits the ready and convenient adjustment of the burner to the vertical angular and lateral position desired by means spaced from the furnace wall, and which are thuseasily accessible and can be kept free of dirt. As disclosed, the first turnbuckle permits attainment of the desired angular dispositionof the burner in a vertical plane by rotation of sleeve 42 in the appropriate direction. Following such adjustment, the burner may be adjusted laterally by the rotation of sleeve 55 on the second turnbuckle, which slides the mounting as a whole laterally upon the spacer tube o and the'horizontal portion of the U-shaped bar |2.

Although a preferred embodiment of the invention has been shown and described, it is to be understood that the invention is capable of numerous variations obvious to those skilled in the art. The invention is therefore to be deflned in the following claims.
