WASHINGTON. D. C. UNITED STATES PATENT OFFICE. JOHN LEE COX, OF KENDRA, ONTARIO, CANADA. OIL-STOVE. To'all whom-it may concern Be it known that I, JOHN LEE COX, a subject of the King of Great Britain, and a resident of the town of Kenora, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Oil- Stoves, of which the following is the specification. The invention relates to improvements in oil stoves and the object of the invention is to provide a stove of the above class especially adapted for household useand which is arranged so that it can be inserted in the lid opening of an ordinary stove and used to heat the stove.- A further object of the invention is to provide an oil stove which will produce a very intense heat for the amount of fuel consumed, and a still further object is to construct an inexpensive, easily assembled stove having few parts and arranged such that it can be readily opened and cleaned. With the above objects in view the invention consists essentially in a pan provided with a hinged top and forming a combustion chamber, the pan having an opening in the side thereof, a feed pipe connected to the pan and entering the same and having the inner end coiled withinthe combustion chamber and terminating ina jet, air ducts opening to the combustion chamber at a point adjoining the jet and an asbestos or other similar absorbent noninflammable material contained in the base of the pan, the parts being arranged and constructed as hereinafter more particularly described and later pointed out in the appended claims. Figure 1 represents a side view of the device as it appears inserted in the lid opening of the ordinary coal or wood stove. Fig. 2 represents a plan view of the oil stove. Fig. 3 represents a vertical sectional view centrally through the same, parts being shown in side elevation. Fig. 4 represents a horizontal sectional view through the oil stove, the section being taken in the plane denoted by the line XX' Fig. 3. Fig. 5 represents a vertical sectional view through the lid, the section being taken in the plane denoted by the line Y-.Y' Fig. 2. Fig. 6 represents a detailed vertical sectional View through a portion of the lid and pan, the section being taken in the plane denoted by the line Z-Z Fig. 2. Specification of Letters Patent. Application filed April 6, 1914. Patented July as, 1914. Serial No. 830,029. In the drawing like characters of reference indicate corresponding parts in each figure. 1 represents a pan preferably of a cylindrical form provided with an out-turned top flange 2 and having an opening3 formed in the side thereof. The pan is preferably cast from iron and is formed in casting with a cross strip l to which I have attached by suitable hinges 5, the cover or lid 6 arranged to shut down on the pan and inclose the combustion chamber 7 The lid is formed with a central opening 8 which communicates in the present instance withfour similar ducts or passages 9, the central opening and ducts being preferably cast in the lid. 10 is a feed pipe leading from an oil supe ply tank 11 and secured permanently to the cross strip 4 through which it passes, the lower end of the pipe being formed into a coil 12 which terminates in a nipple or burner 13 located just below the opening 8 and slightly to the side of the center. thereof. The jet is deflected slightly downwardly anddirected toward the opening 3. 14 is a valve controlling the supply of oil through the pipe. 15 is an asbestos or other such absorbent and non-inflammable material located in the base of the pan beneath the coil.. 16 and 17 are lugs cast on the pan and located slightly below the flange 2. I have not shown any means for locking the lid closed but any suitable device could be used for this purpose if desired; The oil stove is specially constructed to be inserted within the lid opening of the ordinary wood or coal stove. The top of such a stove is indicated in Fig. 1 by the reference numeral 18. Such stoves are equipped with lid openings 19presenting at their sides a ledge 20 on which the lid rests. The pan of my stove is arranged so that when the lid of the ordinary wood or coal stove is removed the pan can be inserted in the lid opening with the flange 2 resting on the ledge 20 and the lugs 16 and 17 projecting beneath the ledge. The lugs then prevent any possibility of the oil stove being upset, as any upending action due to the weight of the tank 11 is offset by the lugs. To light the oil stove when installed as shown in Fig. 1 one has simply to raise the lid 6, pour a small quantity of oil onto the asbestos pad 15 and then ignite the oil, the lid being afterward closed. The chamber 7 becomes hot and accordingly heats the coil. Then the coil has become more or less heated the needle valve is opened and the oil flows down from the tank 11 through the pipe 10 to the coil where it is heated and is" vaporized and ignites of itself the instant it escapes through the jet. Combustion is supported by the air admitted through the ducts 9 and the opening 8. I wish to draw particular attention to the fact that the air supplied to support combustion is heated in the ducts prior to entering the combustion chamber. It is obvious that the lid will become heated at the onset and will remain intensely hot during the time the stove is inuse. The flame from the burner or jet is deflected down by the incoming air with the result that it plays on the coil and heats the same to an intense heat thereby insuring the positive vaporizing of the oil passing through the coil. I might remark that when the device is in use a tongue of flame proj ects through the opening 3 and plays across practically the full width of the ordinary coal stove and also that when my oil stove is used in the ordinary coal or wood stove all the air drafts of the stove require to be closed. Vhat I claim as my invention is; 1. An oil stove comprising a pan having an opening in the side thereof, a hinged cover normally closing the pan and provided with a centrally located air opening and a coil contained within the pan having one end communicating with a supply tank and the opposite end thereof formed into a burner, said burner being directed toward the opening in the side of the pan and located adjoining the opening in the top of the pan, as and for the purpose specified. 2. An oil stove comprising a pan having an opening in the side thereof, a hinged cover normally closing the pan, said cover being provided with a centrally located air opening communicating with air inlet ducts formed in the cover and a coil contained within the pan and having one end communicating with a sup-ply tank and the opposite end formed into a burner directed toward the opening in the side of the pan and located at a point adjoining the opening in the cover, as and for the purpose specified. 3. An oil stove comprising a cylindrical pan fitted with a side opening and a top outstanding fiange, a hinged cover normally closing the top of the pan and provided with a centrally disposed air opening communie eating with a plurality of radiating air ducts formed in the cover, a coil contained within the pan and having one end communicating with a supply tank and the opposite end formed into a burner, the said burner being directed toward the opening in the side of the pan and being located directly beneath the air inlet opening in the cover and a noninflamma-ble absorbent material contained in the bottom of the pan beneath the coil, as and for the purpose specified. Signed at l/Vinnipeg this 27th day of February 1914;. JOHN LEE COX. In the presence of-- G. S. RoXBUReH, S. SEBERT. Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. C.
