OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 476,445, dated June 7, 1892.

Application filed February 5, 1891. Serial No. 380,312. (No model.)

To all whom it may concern.-

Be it known that I, CARL F. Bnosrnoln, a citizen of the United States, residing at Chicago, Cook county, Illinois, have invented a new and useful Improvement in Oil-Burners, of which the following is a specification.

My invention consists of aburner designed particularly for stoves and ranges adapted for burning petroleum, gasoline, kerosene, or other hydrocarbon oils, in which the oil is allowed-to enter through a feed-pipe and is vaporized by the heat of the burner concentrated in a grate or radiator and air drawn in by the draft produced by the flame and thoroughly mixed with the vaporized oil to give a perfect combustion.

It further consists of details of construction hereinafter more fully described, and particularly pointed out in the claims.

Figure 1 is a plan view of a stove with a part of the top broken away, showing my burner. Fig. 2 is a side elevation of the stove, a part of the side being broken away, showing the burner on a middle section view. Fig. 3 is a plan view of the burner, the top damper being removed. Fig. 4: is a plan view of the pan of the burner. Fig. 5 is a side elevation of the same. Fig. 6 is a top view of the grate. Fig. 7 is a bottom view of the same. Fig. 8 is a top view of the air-nozzle partially broken away, showing the perforations. Fig. 9 is a bottom view of the same.

A represents the stove; B, the burner-pan; C, the feed-pipe; D, the reservoir; E, the feedcock; F, the air-nozzle; G, the grate; H, the damper, and I the chimney-flue.

The operation of the burner is as follows: The feed-cock is opened and the oil allowed to run into the bottom of the pan of the burner and there it is ignited, when it burns slowly for a time until the burner becomes heated. XVhen the heat reaches a certain point, the oil is vaporized and the gases begin to burn, producing a much more intense flame than the burning of the oil. Then by regulating the supply of oil the amount of gas generated is regulated as well as the heat of the flame. The flame passing up the flue produces a draft which draws in the air through the passage under the burner in the fire-box, as indicated by the arrows, and

through the perforated nozzle F, the draft through the fire-box being entirely out off by the burner, leaving only the passage through F open. This nozzle is spread out and its under face perforated so as to distribute the supply of air pretty generally all over the grate. The grate is made up of a number of upright partitions with air-spaces between them and broken by circulatingpassages which connect one air-space with another. This construction gives a large radiatingsurface and also a system of air-passages which tend to thoroughly mix the gases coming up from below and the air being fed in above. There are also channels in the bottom of the grate to allow the oil as it runs in to spread out over the bottom of the pan and be more rapidly vaporized. The grate rests upon the bottom of the pan in order to keep it hot and assist in vaporizing the oil. The oil enters just at the upper edge of the grate in the back and trickles down into the pan before much of it is vaporized, because this portion of the burner is comparatively cool, the air being drawn in over it. The combustion in the burneris concentrated in the grate, which when the burner is in full blast becomes intensely heated and glows like a bed of burning coals, keeping the burner-pan hot and rapidly vaporizing the oil as it runs into the bottom of it. Then as the gases rise through the bars of the grate they are heated and mixed with the air from above and thoroughly consumed. The air-nozzle is extended out to a point in the middle in order to divide the flame directing it onto the lids of the stove at each side. The damper H is pivotedin the middle and may be turned to direct the flame to either side of the stove, as desired, or, if preferred, may be removed entirely.

The grate, pan, and air-nozzle are separate parts fitting into one another and may be separately renewed when burned out.

I prefer to burn refined petroleum in my 9 burner; but other hydrocarbon oils may be used or any other oils that can be readily vaporized by the heat of the burner.

I have shown my burner as applied to a stove or range; but it may be used for other purposes, provided there is a fine sufficient for producing the necessary draft to draw in the supply of air.

I do not wish to limit myself to the exact construction shown and described, as the same may be slightly varied without departing from the spirit of my invention.

That I claim, and desire to secure by Letters Patent, is-

1. The herein-described oil-burner, consisting of the combination of the burner-pan, the grate located within said pan, the oil-feed by which the oil is fed below said grate, the airfeed by which the air is fed above said grate, and the chimney-flue, all substantially as shown and described.

2. The herein-described oil-burner, consisting of the combination of the burner-pan, the grate resting upon said pan, the oil-feed, the air-feed, and the chimney-flue, all substantially as shown and described.

3. The herein-described oil-burner, consisting of the combination of the burner-pan, the grate, the oil-feed, the air-feed by which the air enters in close proximity to the oil, and the chimney-flue, all substantially as shown and described.

4. The herein-described oil-burner, consisting of the combination of the burner-pan, the

grate, the oil-feed, the air-feed having a wide nozzle by which the air is spread over the grate, and the chimney-flue, all substantially as shown and described.

5. The herein-described oil-burner, consisting of the combination of the bu rner-pan, the grate having upright partitions and air-passages through them and channels along the bottom of the grate, the oil-feed, the air-feed, and the chimneyflue, all substantially as shown and described.

6. The herein-described oil-burner, consisting of the combination of the burner-pan, the grate, the oil-feed, the airfeed having a wide nozzle with a projecting portion across the middle of the grate, the pivoted damper, and the chimney-flue, substantially as shown and described.

7. The herein-described oil-burner, consisting of the combination of the burner-pan, the grate, the oil-feed feeding the oil below the grate, the air-feed feeding the air above the grate, and the chimney-flue, all substantially as shown and described.
