FREDERICK D. STALFORD, 0F FREDERICK, OKLAHOMA.

CRUDE-OIL BURNER.

T 0 all whom it may concern:

Be it known that I, FREDERICK D. STAL- rono, citizen of the United States, residing at Frederick, in the county of Tillman and tate of Oklahoma, have invented certain new and useful Improvements in Crude-Oil Burners, of which the following is a specification.

This invention relates to certain new and useful improvements in burners for crude oil or similar liquid fuels and particularly to improvements on the apparatus shown in my pending application, Serial No. 516,340, filed on the 7th day of September 1909.

The general object of the invention is to provide a simple, durable and efficient construction of crude oil burner which may be placed in the fire-pot of any ordinary stove which in its operation will effectively consume the fuel and secure or produce a hot flame, and it includes a plurality of troughs which may be moved successively into operative position as the troughs become corroded or otherwise unfit for use. v

The particular object of this improvement of my pending application is to provide means'whereby the oil may be more economically burned when a low fireis desired, these means, however, being so arranged that a considerably greater heat may be secured when required.

To this end the invention consists in the arrangement of the parts and details of construction described in the following speci fication and particularly set forth in the claims appended.

For a full understanding of the invention reference is to be had tothe following description and accompanying drawings, in which Figure l is a perspective view of my burner. Fig. 2 is a transverse sectional view thereof showing the same in place within the fire-box of a stove. Fig. 3 is a longitudinal section of the burner, the partition plates being omitted and Fig. 4 is a trans verse section enlarged of the central portion of :the burner showing certain details of construction.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

My improved crude oil burner includes a revoluble body portion which comprises two heads 1 which are preferably circular,

and any desired number of substantially radiating partition plates 2 secured at their ends to the heads and thus forming a plurality of troughs or pockets 3 in which the crude oil or similar liquid fluid is intended to be burned. The reyoluble body portion also includes a central longitudinal shaft which is journaled at its ends as indicated at 4 in bearingsformed for it in standards or uprights 5 which form part of a supporting frame. This frame is preferably supported on laterally extending feet 6 connected to each other by a bracing crossbar 7 The improved burner is thus adapted to rest upon the grate B of a stove A of any usual type.

8 designates an air induction hood. This 1s preferably provided with a tapering tubular neck 9, one end of which is formed with damper regulated openings 10 through which varying proportions of air may be admitted into the interior of the hood, this portion of the device being thus adapted to be mounted in and protrude from the ordinary damper opening of a stove. The end of the neck 9 is also formed with a central opening through which the fuel supply pipe 11 passes, said pipe being connected at one end to any suitable source of oil supply such as a tank, (not shown). The inner end of the supply pipe 11 has a cross-arm or crosspipe 14: connected to it, this pipe being provided with a plurality of downwardly opening orifices 15 through which the crude oil drops into that particular trough 3 which is uppermost. The pipe 14 is supported at its ends in the upper ends of the standard 5, as indicated at 16. Preferably the hood 8 is supported at its inner end byresting upon the pipe 14:, and the hood at its inner extremity isformed with the oppositely extending flared flanges 17 designed to extend partially over and inclose or partially cover the top-of the'uppermosttrough 3 in the operation of the device so that the air passing into the trough 3 from the hood 8 will be detained within the trough sufliciently to become thoroughly commingled with the fuel dropping from the orifices 15, whereby combustion will be more thoroughly pro moted. These outwardly projecting flanges 17 also act as directing wings directing the flame on each side outwardly between the lateral walls 2 of the troughs 3, and the edges of the wings and flanges 17 and thus causing an upward blast of air and flame.

troughs that when any one trough is turned so as to be immediately beneath the pipe 14:, the receptacles 18 will be immediately beneath the orifices 15 in the tube 1 and thus the fuel oil passing into the transverse pipe 14 will drip into the cups 18. If the supply of oil is relatively moderate the oil will be consumed in these cups 18 at about the same rate as it drips into the cups and hence the fuel oil will not overflow the edges of the cups and fill the troughs. If, however, the supply of oil is greater than can be consumed in the cups, the oil will overflow the receptacles or cups 18 and fill the lower portion of the troughs. The purpose of this will be stated hereafter. TVhile I may support these cups or receptacles 18 in any suitable manner within the troughs l have shown two means of accomplishing this end. In the construction shown in Fig. 2 the lower extremities of the cups are screwthreaded and inserted in sockets 21 formed upon the bar 19. In Fig. 4, however, the bar 19 is shown as formed with screwthreaded bores on its sides, and each of the cups has passing through it the attaching screw 22 whose lower end enters the screwthreaded sockets or bores. The outer end of the screw is countersunk into the bottom of the cup or receptacle. I do not wish to limit myself, however, to any specific manner of supporting these cups or receptacles within the compartments or troughs.

The operation of my improved burner will be apparent. The device is supported within the fire-box of a kitchen range or other stove as fully illustrated in my prior application before referred to. The revolu ble body portion is turned as by a handle applied to the square end a of the shaft l so that one of the troughs or compartments 8 is brought into position immediately beneath the discharge end of the hood 8 and of course immediately beneath the perforations 15 of the pipe let. The oil is then permitted to flow into the pipe 11 and after it drops through the orifices 15 and is lighted will be met by the down draft of air passing into and through the hood 8 so that the fuel will become thoroughly commingled and consumed with the minimum of residue.

N here a relatively small fire is desired the flow of oil is so regulated that it will drip into the cups or receptacles 18 about as fast as it is consumed, as a consequence these cups or'receptacles will not overflow, but

same time the walls of the troughs are not attacked by the flame and are protected from undue and unnecessary corrosion. Then, however, it. is desired to increase the heat produced by my burner and increase the size of the flame, oil is allowed to flow in greater quantities through the supply tube and flow in such quantities into the cups 18 that it will overflow therefrom and fill the lower portion of the trough as well as the cups. There will then be a body of oil extending over the entire bottom of the trough and around the cups from which the flame will be fed with fuel. I can thus secure by my invention a moderate fire or a heat of as great an intensity as is necessary.

It will be seen that the individual cups or receptacles 18 may be readily detached from the support 19 and replaced by new cups in case they become old or worn out, corroded or otherwise damaged.

It will also be seen that the use of these individual receptacles for a low fire will 95 tend to lengthen the life of the burner as a whole for the reason that the surface of the trough is under these circumstances not subjected to the action of the oil or the action of the flame.

Having thus described the invention what is claimed as new is:

1. A burner of the character described including a supply pipe with dripping orifices, a revoluble member having a plurality of 105 troughs mounted beneath the supply pipe, and a longitudinally extending series of separate receptacles mounted in each trough. and adapted to be brought into registry with said orifices.
