Application :tiled May 1, 1924. Serial VNo. 710,465.

@ur invention relates to the class of burners in which petroleum fuel products of the heavier grades are employed for heating and similarl purposes, and an' object of our invention, among others is the production of an apparatus that shall be extremely simple in construction and particularly eilicient in the results attained by itsoperation.

One form of apparatus embodying our invention and in the construction and use of which the, objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- Figure 1 is a top view oi' the base of an oil burner embodying our invention.

Figure 2 is a View in side elevation of the burner as a whole.

Figure 3 is a view in vertical sectionthrough the burner on a plane denoted by the dotted line 3 3 of Figure 1.

Figure 4 is a top view of the' burner. Figure 5 is a detail view illustrating the construction of one type of wick employed with our improved burner.

Figure (i is a view of another type of Wick, having particular advantages in connection with our improved burner.

Figure 7 is a perspective view of one corner of our improved burner illustrating the construction thereof. f

Figure 8 is a view, scale reduced, illustrating the arrangement of a battery of our improved burners. I l

ln the accompanying drawings the n`umeral indicates a bur er base that may be suitably constructed in any desired Inanner from metal of any proper kind, this base as a Whole being rectangular in form, as illustrated in Figures 1 and 4; and having main supply passages 16, preferably -oitcruciztorm arrangement, as illustrated in dotted lines in Figure 1 of the drawings, these passages being connected as at the center with a main supply pipe 17 leading from a suitable source to be hereinafter described.

This improved burner preferably com` of these outlets as may be desired being employed, two of such outlets 2O in the strueture herein shown being supplied for the inner burner, and on opposite sides thereof, and four of the outlets 21 being employed for the. outer burner, such outlets being located one at the center of 'each of the four sides of the burner and as illustrated in Figure 1 of the drawing. v

Openings 22 are formed through the base 15 in line with each of the passages 16, as a means for access to such passages for any desired purpose, and these openings are closed by means of plugs 23, and as illustrated in Figure 3 of the drawings.

Y Wicks 2li-25 are located in the inner and outer burners, respectively, and these wicks may be of any desired construction, in the form illustrated in Figure 3 each wick comprising an ordinary 'form of woven cotton fabric, or it may be of asbestos. In the form shown in Figure 5 an im rov'ed wick comprises two outer layers 26 oi) asbestos or any other suitable material and an inner supporting member 27 of corrugated sheet steel or other suitable metal. The form of wick shown in Figure 6 comprises a piece of asbestos 28 formed with corrugations'ex-- tending in the direction of depth of the' Wick, it being understood that all of the.

wicks hereinabove referred to will prefer ably extend around the burner in the groove of which they are located. y

Each ofA the grooves 18 and 19 have widened mouths 29, each terminating at its bottom in a shoulder 30, upon whichshoulder a burner top is supported. This top comprises an inner 'rectangularly shaped member 31 and an outer rectangularly shaped member 32, each of said members, except as to size anda bulged portion in the outer member to be hereinafter described, being of the same general formation and a description of one of said members will, therefore, be understood to apply generally to both ot said members.

These members each comprises 'an outer wall 33 and an inner wall 34 both formed from sheet metal and having flanges 35 at 'their upper ends, and a cover plate 36 is secured to the upper edge of the inner wall of the inner member 32 tocover the space within and bounded by a said wall, said plate having perforations 38 extending through the plate into said space within said inner wall. A. cover plate 37 is similarly secured to the inner wallof the outer member 32 of the burner and has perforations 39 extending through the plate into the space between the two members 3l and 32, this plate 37 also having a central opening 40, the edge of which is spaced from the outer edge of the cover plate 36, and as shown in Figure 4 of the drawings.

The cover plates 36 and 37 have lips ile-42 that rest upon the upper surfaces of the {langes 35 of the inner walls 34, said lips being located on oppositely disposed edges of said plates, and eachof said plates also has, at its opposite edges, dependin flanges 43-44 that project downwardly into the opening bounded by the flanges on the inner walls 34, and as shown in Figure 3 of the drawings, said cover plates being thus held from vertical and horizontal movement.

l The several walls 33 and 34 are spaced a art a distance substantially equal to the widt of the mouths 29, and tie-rods 45 extend in op'-l poslte directions through the several walls above described to unite them in a burner shown a battery of burners arranged in two parallel rows, these burners being evenly spaced apart in all directions and secured to a base plate 48.

This bulging of the walls acts as a reinforcement to stiffensuch walls and impart rigidity thereto, and as a further end to this `means ribs may be formed extending across the walls near their bottom edges, as shown l in Figure 2 of the drawings.

The flanges hereinbefore described located at the tops or mouths of the tubes in addition to acting as-rests and supports for the top 'plates also serve as stliening means for the tubes.

In accordance with the provisions of the patent statutes we have described the princi ples of operation of our invention, together with the device which we now consider to represent the best embodiment thereof; but we desire to have it understood that the device shown is only illustrative, and that the invention may be carried out by other means and applied to uses other than thoseabove set out. v

We claim i A burner comprising flue walls arran ed in concentric relation, burner grooves be tween the walls, horizontal flanges at the u per ends of the fiue walls, concentric cover p ateshaving lip extensions supported on the flanges of the iiue walls and arranged to allow unobstructed upward passage of heat from the burner grooves, and downwardly extending flanges on the cover plates located within and contacting the flanges on said flue walls.
