Application November 14, 1932 SerialNo. 642,497 i 6 Claims.

This invention relates to oil burners, and more particularly to a novel form of attachment adapted to be supported upon the top of a range oil burner of the concentric shell type beneath the cover lids of the range.

One object of this invention is to provide an attachment of the above nature havingmeans for selectively producing a generally distributed heating, or for directing the flame upwardly at the center to produce 'a localized heating effect.

A further object is to provide anattachment of the above nature which may be detachably supported upon the top of such an oil burner for thereof, and thereby producing a more complete combustion therein.

A further object is to provide an oil burner attachment of the above nature which will be simple in construction, inexpensive to manufacture, easy to install and manipulate, compact, ornamental in appearance, and very efficient and durable in use.

With these and other been illustrated on the objects in view there has accompanying drawing,

7 one form in which the invention may be conand flames of burning fuel vapor veniently embodied in practice.

In the drawing:

Fig. 1 is a side elevation of the cover attachment as it appears when supported upon a conventional form of oil range burner.

Fig. 2 is a transverse sectional view of the cover attachment.

Fig. 3 is a top plan view of the same.

Fig. 4 is a perspective inverted view of the attachment.

It has been customary in the past to provide range oil burners of the concentric shell type with annular cover plates or discs which tended to obstruct the free upward flow of the hot gases and air, thus causing incomplete combustion and the production of soot and odors.

By means of the present invention, the'above and other disadvantages have been avoided.

Referring now to the drawing in which like reference numerals denote corresponding parts throughout the several views, the numeral indicates a multi-shell range oil burner of the usual construction, said burner consisting of an outer imperforate cylindrical shell 11, and a pair of perforated inner shells l2 and 13. The shells 11, 12 and 13 are concentrically supported upon a base 14.

The cover attachment 15 forming the subject of the present invention comprises a bottom cylindrical rim 16, an upper frusto-conical apertured perforated baifie plate 17 secured to'said rim, and a removable perforated cover lid 18 covering the aperture in said bafile plate.

In order to support the attachment 15 upon the top of the burner shells 11, 12 and 13, the rim 16 is provided with three arcuate inwardly pressed sections or spider members 19, the lower edges of which are adapted to rest upon the top edges of the shells 11, 12 and 13. By means of this construction, three spaced lateral flue passages 20 are provided in said rim 16.

As most clearly shown in Fig. 2, the rim 16 is preferably made slightly larger in diameter than the outer shell 12 of the burner 10, so as to permit an additional supply of air to pass up into the combustion space within said. attachment, and also to enable the attachment to fit various sizes of burners.

The frusto-conical bafiie plate 17 is provided with a depending annular flange 22 which is adapted to fit within the upper end of the rim 16 and may be permanently attached thereto,

as by spot welding. Moreover, the upper end of the plate 17 is provided with an upturned flange or neck 23 for cooperating with a depending lip 24 on the cover lid 18, whereby said cover lid 18 will be held from sliding out of position.

In order to permit the cover lid 18 to be detached from the cap member 15, whenever desired, provision is made of an eye hook 25 which may be rigidly secured to said lid, as by a pair of nuts 26. The hook 25 serves as a handle by means of which a tool, such as a stove poker or lid lifter, may be readily engaged.

Operation In operation, the cover attachment 15 will first be positioned above the burner unit 10 and lowered downwardly until the curved spider members 19 rest upon the top edges of the three concentric shells 11, 12 and 13. The increased chimney effect or draft thereby produced will render the combustion more complete and compel the products of combustion to pass partly out through the passages 20 and partly through the perfora- 100 tions in the conical plate 15 and lid 18, thus causing the heat to be generally diffused. By detaching the-cover lid 18, the heat may be directed upwardly through the center of the neck 23 for causing an intense heat to'be directed 105 locally upon the top of the stove.

While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, 110

and that the invention is not to be limited to the specific disclosure but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claims.

Having thus fully described the invention what is claimed as new, and for which it is desired to secure Letters Patent, is:

1. In an oil burner cover attachment, a cylindrical rim, means extending inwardly from said rim for supporting it upon the outer shell of a range oil burner, and a perforated baffle for said rim, said baifie having a central aperture, and a cover for said aperture adapted to be detached to permit the direct heating of the range cover lid located above it.

2. In an oil burner cover attachment, a cylindrical rim having a plurality of lateral openings therein, a perforated baflle member fitted within the top edge of said rim, said member having a central aperture, a removable cover lid for closing said aperture, and means attached to said rim for supporting it upon a range oil burner.

3. In an oil burner cover attachment, a cylindrical rim having a plurality of lateral openings therein, a perforated frusto-conical baille member fitted within the top edge of said rim, said member having a central aperture, a removable cover lid for closing said aperture, and means attached to said rim for supporting it upon a range oil burner.

4. In a cover attachment for an oil burner, a cylindrical rim, a frusto-conical perforated baffle plate secured to the upper end of said rim and having a central vertical flue passage therein, a detachable cover lid adapted to close said vertical passage, and means on said rim for supporting it upon a range oil burner.

5. In a cover attachment for a range oil burner, a cylindrical rim, a plurality of arcuate members pressed inwardly from the side walls of said rim and adapted to rest upon the top of said burner, a frusto-conical perforated baffle plate attached to the upper edge of said rim, said plate having a central flanged aperture therein, a perforated cover, lid having a depending rim adapted to fit loosely about said flange, and handle means attached to said cover lid for removing the same.
