SPECIFICATION forming part of Letters Patent No. 742,916, dated November 3, 1903.

Application filed March 18, 1902- .Serial No. 98,842. (No model.)

To aZZ whom i2; may concern:

I Be it known that I, HARLEY LEROY SHER- WOOD, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Kerosene-Oil Burners, of which the following is a specification.

My invention relates to improvements in kerosene-oil burners for domestic stoves or ranges, for generation of steam for propelling automobiles, or for other analogous uses, the object of my invention being to provide a device of this character which shall be cheap and simple in construction, which shall be compact in form and size, which can be readily cleaned without requiring expert assistance for that purpose, and which shall be strong and durable and not liable to get out of order.

My invention therefore resides in the novel construction, combination, and arrangement of parts for the above ends hereinafter fully specified, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of myimproved oil-burner. Fig. 2 is a horizontal section thereof through the oil-channel. Fig. 3 is a longitudinal section on the line A A of Fig. 2. Fig. 4 is a cross-section on the line B B of Fig. 2. Fig. 5 is a perspective view of the spreader detached. Fig. 6 is a similar viewof a support for the spreader. Fig. 7 is a similar View of the base-plate. Fig. 8 is a perspective view of a modified form of burner.

Referring to the drawings, it will be seen that the burner proper consists of a single casting having straight sides 2 and ends 3 and having its sides joined to the center by a bridge 4. In making said casting the sides and ends are cored completely through from end to end, so that the casting when taken from the mold has correspondingpassages 5 6 in said sides andends. Said passages cross each other and open into the ends and sides of the casting, so that by closing the ends thereof there is formed in the casting a peripheral channel making a complete circuit. An opening Z is also made from one side of the burner into the middle of the side conduit 5, and into said opening is screwed the end of an oilpipe 8. The oil therefore entering through said oil-pipe 8 divides and flows to the right and left along the side passage 5 in the directions shown by the arrows and then around by the end passages 6 and then flows to the middle of the side passage 5 opposite to that at which it enters. The two streams of oil at this point unite and pass along a channel 9, formed in the bridge in casting and extending to the middle of said bridge. It then falls into a downward extension 10, .depending centrally from said bridge. In the opposite sides of said extension 10 are screwed two gas-pipes 11, closed by caps 12 and having apertures 13, through which the gas can escape. The gas emerging from said gaspipes strikes the wings 14 of a spreader 15, resting upon supports 16, laid upon lugs 17,

formed in one piece with the burnercasting.

By means of the wings of this spreader the flames are deflected upon the burner, thereby heating the entire mass, and thus'vaporizing the oil which is traveling in the oil-channels.

The burner rests removably upon standards I sides of said supports, and the spreader is held in place upon said supports by being passed between upwardly-extending pairs of lugs 22 thereon .and having also downwardly-extending lugs 23, preventing lengthwise movement of the spreader. Thus all the parts can be assembled in a few seconds of time and can be detached with like rapidity.

Great difficulty has heretofore been experienced with oil-burners in keeping the same cleaned from the deposition of carbon and non-vaporizable ingredients in the conduits of the oil-burner. It has been the main object of my invention to provide a burner which whileabsolutely non-leakable shall permit'of cleaning of the passages of the oil very readily. It will be seen that the four main parts of the conduit along which the oil travels can be opened from end to end. They are normally closed either by short pipes 24, as shown in Fig.1, or by plugs 25, as shown in Fig. 8. Both the pipes and the plugs, however, can beunscrewed, and when unscrewed the side con-- duits andthe end conduits will be open from end to end, so that a brush or other suitable cleaning device can be passed freely therethrough and the same can be thoroughly cleaned. The short conduit in the bridge is also closed at its end by a short pipe or by a plug, so that any deposit therein can be pushed forward by a brush and will fall into the vertical channel in the downward extension 10, from which it can be removed by unscrewing a plug 26 .closing said vertical channel. In the modification shown in Figs. 1 to at the ends of these side and end passages are closed by short lengths of pipe '24, having end caps 27 thereon.

The ob-. ject of this is to permit any residuum or oil that cannot be vaporized to be forced by the current into said pipes, which thus serve as receptacles for heavy or non-vaporizable oil and other residuum and permit of the: oil-burner being used for a much longer period without cleaning, since such residuum can be collected in said short pipes without screwed short pipes 28, closed by caps, said pipes also serving to catch the residuum and non-vaporized oil and receive and hold the same until it is necessary to clean the burner.

By providing the body of the burner with these closed-ended projections and locating them adjacent to or virtually in the path of the flames from the gas-orifices and the deflectors it is evident that the oil or gas which is forced into them by the process of volatilization will be subjected to a greater degree of heat than would be possible if it were not thus held substantially stationary before it returns to the main portion of the conduit on its way to the gas orifices. In the cheaper form of burner shown in Fig. 8. however, such short pipes are dispensed with, and the ends of the side and end passages are closed merely by plugs.

. The base-plate is made to incline downward toward the center from all sides, as shown, so that oil which is poured thereinto to start the fire will burn with the greatest efficiency for that purpose.

I claim- 1. Inan oil-burner, an angular body having a continuous conduit therein, the ends of which conduit at the angles cross each other and extend to the exterior of the body, said body being perforated upon its under side to communicate with said crossings, stoppers in said perforations and in the end of the conduit, an extension depending from the body and provided with oppositely-extending perforated pipes, and a removable deflector on top of the body the ends of which extend be- In like manner in said modifi cation the yond the body, and are each provided with a plate directly above one of the perforations in said pipes, substantially as described.

2. In an oil-burner, a rectangular body provided with a centrally-located bridge, said bridge being perforated a portion of its length and provided with a hollow depending extension communicating with said perforation,

said body having also acontinuous circuitous conduit, the ends of which cross each other at'the corners and extend to the exterior of said body and the intermediate portions communicate with an oil-supply and with the perforation in the bridge, respectively, the body being perforated upon its under side to communicate with the conduit at said crossings, elongated cap-like hollow stoppers in said perforations and in the ends of the conduit, oppositely-extendingperforated pipes in the extension of the bridge, and a removable deflector above the body, each end of which is provided with a plate directly above one of the perforations in said pipes, said perforations and plates being exterior of the body and within the vertical plane of said stoppers, substantially as described.

3. In an oil-burner, a hollow body provided with laterally-extending closed-ended hollow projections, perforated pipes communicating with said body on its lower side, said perforations lying beyond said body but within the vertical plane of said projections, and a spreader on the body, each end of which is provided with a plate directly above one of said perforations, substantially as described.

4. In an oil-burner a hollow body provided with pairs of standards on top, and a hollow extension onits bottom, having gas -orifices communicating therewith, a support removably carried on each pair of standards provided with lugs engaging the standards and preventing longitudinal movement of the support and having also lugs for engaging the spreader, and a spreader removably carried on said supports, the intermediate portion of which is provided with lugs for engaging said supports and each end of which is. provided with a plate directly above one of said orifices, substantially as described. 7

5. In an oil-burner, a hollow body provided with pairs of standards on top and a hollow extension on its bottom, having gas-orifices communicating therewith, a support on each pair of standards provided with lugs, and a spreader on said supports, the intermediate portion of which is provided with lugs for engaging with said supports and each end of which is provided with a plate directly above one of said gas-orifices, substantially as described. 6. In an oil-burner, an incline-bottomed base provided with shouldered projections, a hollow rectangular body on said shoulders and provided with hollow closed-ended projections upon its exterior and a centrally-1ocated hollow extension, the lower end of which extends nearlyto the base and is providedwith ICC oppositely-locatedpipesextending lengthwise of the body and perforated adjacent to the projections at each end of the body, and a removable spreader on top of the body, each end of which is provided with a plate directly above one of said perforations, substantially as described.
