T0 all whom it may concern:

Be it known that I, EDGAR RICHARD NVA- TERMAN, a citizen of the United States, residing at Helena, in the county of Lewis `and Clarke and State of Montana, have invented a new and useful Oil-Burner, of which the following is a'speciication.

My invention is an improved oilburner especially adapted for use as an attachment for ordinary cooking-stoves, ranges, and heaters, and to burn oil, either crude, refined, or distillate; and it 'consists in the peculiar construction and combination of devices herein after fully set forthl and claimed.

In the accompanyingdrawings, Figure 1 is a' perspective View of my improved oil-burner,

showing the same as'an. attachment to an ordinary cooking-stove. Fig.`2 is a top plan View showing the top plate of my improvedl burner. Fig. 3 is a vertical sectional view of my improved burner, taken on a plane indicated by the line a a of Fig. 2. Fig. 4 is a top plan view showing the bottom plate and the generating-cone formed thereon. Fig. 5 is a detail elevation of the clamp for connecting my improved oil-burning attachment to a stove. Fig. 6 is a detail'perspective view. Fig. 7 is a detail sectional'view showing the proiles of the generating-cone and the dared opening in the top plate". Figs. 8,9, 10, and 11 illustrate modifications of my improved burner. y

In the embodiment of my invention I provide a top plate 1, which is preferably cir'cular-in form and is adapted to be substituted for one of the removable lids of an ordinarycooking or heating stove or range. As here Shown, the said top plate is'provided on its' under side with an annular rabbet 2 ofsuch width that the top plate is adapted to beused on stoves of various sizes, the said rabbet` adapting the top plate to be placed in or on a stove-lid opening of any size. The s aid top plate is provided with a feed-pipe3,which extends from a reservoir 4 to contain the oil. The end of the feed-pipe 3, Where-the same is connected tothe top plate, is bent upwardly and then vdownwardly to form a siphon vor gooseneck 5, and the said pipe is preferably provided with a valve 6 to cut off or permit Owing to the curvature 5 in lthe said pipe 3, the supply of oil to the burner inthe lower side of the top plate 1. g 12 or other suitable devices are employed to secure the said hangers to the under side kof ceases assoon as the valve 6 is closed, as will be understood. The inner end of `the feedpipe 3 is connected to an opening 7 in the top plate 1 at a suitable distance from one side of the latter, and near and on opposite sides of the said opening 7 are air-inlet openings 8, which may be of anysuitable form, but are preferably of the form shown in Fig. 2. I also provide a bottom plate 9, which is preferably of the form shown in'Figs. 3 and 4 and has its upper side dished or concaved, as at 10.A The said bottom plate is formed with hangers 11 on its upper side, which are approximately of conical form and the upper ends of which are adapted to enter recesses Screws the top plate, and thereby connect thebottom plate thereto in such manner that the-bottom plate may be readily removed fromv the top plate when desired. On the upper side of the bottom plate, at a point immediately under the opening 7, is a generating-cone 13, which is formed integrally with the bottom plate and is truncated, as shown. The upper portion of the said generating-cone is disposed in a downwardly-tlared opening 14, with which the top plate 1 is provided, which opening 14 forms an extension or lower continuation of the e said opening 7, and it will be observed by reference to Fig. 3 of the drawings that a slight annular channel 15 is formed between the said flared opening 14 and the upper portion'of the said generating-cone. The latter iis' provided with radially-disposed grooves 116, which are formed on its surface and extend-from the base thereof to its apex and serve to conduct the oil from the pipe 3 downwardlyon the said generating-cone toward the bottom plate.

' In operation when myimprovedoil-burner is in use as an attachment to a stove air is drawn downwardly through the openings 8 in the top plate, which openings, being disposed near opposite sides of the generating-cone, cause the air to unite with the vapors or gases from the oil and cause the same to be Aconsumed. It will be understood that owing to the heated condition of the parts of the burner the oil, which is supplied to the apex of the generating cone, is converted into ICO gases or vapors while passing downwardly in the channel 16 of said generating-cone, and hence the oil is entirely consumed as it is fed to the burner. The concaved or dished upper side of the bottom plate adapts the same to hold a small quantity of oil, to be ignited for the purpose of initially heating the burner before the same is started in operation.

My improved burner is adapted for burning crude oil as well as refined or distillate oil, and in the practical operation of my burner I find that the same does not become clogged with carbonaceous residues, and hence does not require to be cleaned and requires practically no attention when in operation.

An annular plate 17, provided on its under side with radially-disposed downwardly-extending tongues 1S, is adapted to be placed around the generating-cone and to rest on the bottom plate at the base of said cone for use in summer.

The base of the generating-cone is hollowed, as at 19.

Owing to the fact that the air which becomes carbureted and consumed by the burner is supplied to the same through the openings 8 inthe top plate when my improved burner attachment is in use in connection with a stove or range, the burner is entirely l unaffected by outside drafts, no matter in rated, recess 25.

what position the stove may be placed 0r to what drafts it may be exposed, and hence there is no danger of the ame becoming extinguished and the burner becoming hushed by the escape without the consumption of the oil. Furthermore, all odors incident to the burning of the oil are confined to the interior of the stove and the flue, and none of the odors escape and become offensive in the room in which the stove is located.

In connection with my improved oil-burning attachment I provide a clamp, which is shown in Fig. 5, for supporting the feed-pipe 3 and the reservoir and enabling myimproved burner attachment to be readily attached to or removed from an ordinary stove. The said clamp comprises an outer section 20, an inner section 21, and a set-screw 22, which connects the same together. The outer section 20 is of approximately semicircular form and has a pair of upwardly-extending jaws 23 24. The latter is wider than the former and is provided with a semicircular, preferably ser- The said inner section 21 is formed on one side with a hook 26, which overhangs the recess 25 and the lower side of which is correspondinglycurved and serrated, as at 27. The opposite side of the upper portion of said inner section 21 is formed with a jaw 28, which somewhat overhangs the upper end of the jaw 23. The feed-pipe 3 is disposed in the recessed opposing sides of the jaws 24 26, the flange of the stove being engaged by and between the jaws 23 28, and by tightening the set-screw 22 the said clamp may be thus readily attached to the stove in position to support the feed-pipe 3 andthe reservoir, as will be readily understood. Furthermore, by slightly loosening the set-screw 22,so as not to disengage the clamp from the flange of the stove-top, the feed-pipe 3 will be turned axiallyin the recesses 25 27 of the jaws 24 26 to enable' my burner attachment to be raised from the stove-opening in which it has-been disposed and turned to one side of the stove-top, as will be understood from an inspection of Fig. 1. The set-screw is here shown as provided with a winged head to enable it to be readily turned by the thumb and forefnger. The outer section 2O has a slot 20a, in which the shank of the set-screw operates, thus enabling the section 21 to be adjusted laterally, as may be required in the operation of the clamp.

By the use of the annular plate 17, which, as before stated, is designed for summer use, the effective superficial area of the cone may be diminished, as said plate when seated on the base of the cone has the eiect of reducing the height of the latter. Hence the size of the flame produced by the action of the burner is diminished when the plate 17 is used. Furthermore, the use of the said plate 17 enables the burner to be more readily started in operation, as said plate becomes initially heated very quickly. Said plate also acts as a delector or spreader.

In Figs. 8 and 9 of the drawings I show a modified form of my invention especially adapted for use for heating purposes in connection with heating-stoves, furnaces, and small boilers. In this form of my invention the door A of the stove or furnace forms the body of the burner and is cast with a box B, which projects from the outer side thereof, and the bottom of which box forms the bot- IOO tom plate or support for the cone or cones, y

of which any suitable number may be used. The top or cover C of the box has an outwardly-projecting flange D at its outer side. The clamps which secure the feed-pipe 3 engage said flange. Said top or cover also has the draft-inlet openings Sformed therein. In this form of my invention the reservoir 4:, as well as the pipe 3, may be supported by the clamps, or the reservoir may be provided on one side with a vertically-disposed strip E, projecting above and below `the reservoir and having a circular opening e in its lower projection and an opening e', enlarged at its lower side, in its upper projection, to enable the reservoir to be supported on a wall or partition of a room by headed nails or screws. In Figs. 11 and 10 of the drawings I show, respectively, a boiler-furnace and a range provided with a door, in which my improved burner is included.

Having thus described my invention, I claim- 1. A burner of the class described, comprising a top plate; a feed-pipe discharging through an opening therein 3 said top plate being further provided with air-inlet open- IIO- ings; and a bottom plate, suspended below and supported bythe top plate, concaved on its upper side and having a generating-cone disposed with its apex under the discharge of the feed-pipe, substantially as described. 2.
