l 'o all wlw/m, t may concern.'

Be it known that I, JACOB J. SMITH, a citizen of the United States, and a resident ol" the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful improvements in Oil-Gas Generators and Burners; and I do hereby declare that the following is a full, clear, and exact description or' the same, reiference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

rlhis invention pertains to an improved type of an oil-gas generator and burner wherein the oil supply pipe is inclined downwardly toward its entrance end to permit the saine to drain toward the supply and prevent impurities or carbonrom entering the carbureting parts oit the device. The inclined supply pipe also serves as an oil vaporizing means which is iirst heated by a starting burner and afterward by a generating burner to generate an oil vapor adapted to be carbureted with air to `form an oilgas. T he generated oil-gas is admitted into a storage tank to be used as a i'uel in said generating burner to perpetuate the process of oil-gas generation and is turthernioreused as a fuel to burn in cooking burners which are integrally formed on said storage tank.

It is an object of this invention to construct an oil-gas generator having an oil supply and generating pipe inclined toward the inlet end to prevent carbonization of the generator parts.

Another object of the invention is the construction oi' an oil-gas generator' and burner wherein the cooking burners are integrally formed on the oil-gas storage tank.

It is also an object of the invention to provide an oil-gas generator' and burner having an inclined oil supply and generat- .ing pipe adapted to be initially heated by a wick starting burner provided with an under feed.

It is a further object of this invention to construct an oil-gas generator and burner wherein oil is heated and vaporized and then carbureted with air to forni an oil-gas :t'uel adapted for use in cooking burners and in a generating burner for the purpose of continuing the process of oil-gas `Generation.

It is an important object oi the invention to provide a generating burner of simple construction wherein kerosene oil is first volatilized by a starting or a generating burner and is then admitted into a carbureter to permit air to be carbureted there with to form an oil-gas.

@ther and further important objects of this invention will be apparent from the disclosures in the speciiication and d 1awings.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

As shown on the drawings:

The reference numeral l, indicates a'large casing, gas reservoir or gas storage tank` provided with an aperture or opening 2, in the front wall thereof, surrounded by an outwardly projecting collar S. integrally formed on the top or each end of: the casing l, is a cooking burner comprising a burner box 4, having a plurality of burner or gas openings or apertures 5, formed in the top wall or plate thereof. The upper corners of each of the burner boxes l, are notched, as denoted by the reference numeral 6, to permit baie plates to be mounted upon the burner boxes it desired. ntegrally formed on the bottom and at one end of the casing` l, and in communication with the interior thereof, is smaller or auxiliary gas casing 7, provided with an inlet opening S, in the' outer end wall thereof, ttor a purpose hereinafter described. Formeel within the casing l, and .separating the interior thereof from the interior of the auxiliary casing T, is a partition or wall Sly-constructed to lezl Ve an opening l0, to permit gas from the auxiliary casing to pass upwardly into the main or upper casing 1.

Rigidly secured to the back of the casing 1, are the upper ends of angle supports or legs 11, the horizontal positions of which serve as feet. Disposed longitudinally in front of the auxiliary casing and extending beyond the ends thereof is a. fuel iniziing or carbureting pipe 12, one end of which is curved to form an elbow 13, having integrally formed on the inturned end thereof a flange rim or ring lll, which is rigidly secured to trie outer end wall of the auxiliary casing Y, to register with the inlet opening 8.

tiecured or projecting into the collar 3, of the main gas casing l, is one end of a stub pipe or neck l59 on the outer end of which is integrally formed or rigidly secured a generating burner disposed in front of the casing 1, and comprising a main pipe 16, of squared or angular cross-section and inclined with respect to the horizontal. The outer end portion Vof the pipe 1G, is turned vertically downwardly to forni a branch pipe 17.

of said generating burner is provided with a plurality of burner apertures or openings 13. The 'front wall of the branch pipe 17, is also provided with a. plurality7 of apertures or openings 19, disposed transversely across said branch pipe near the lower end thereof. Formed at the bent portion or at the elbow of the generating burner is a projection 20, on the end or which is secured a supporting or retaining latch 21,

The projecting finger or free end of the latch 2l., engages and supports the downwardly jnfojecting discharge arni 2Q, integrally formed on the higher end of a long oil. supply or oil-gas generating pipe or tube 23, which is disposed directly in front of the generating burner and is inclined downwardly toward the inlet end 9st, thereof. The inlet arm is directed downwardly and is connected by ineans of a feed or supply pipe 25, with a kerosene or oil supply tank, not shown. of the generating burner 16, is a bracket 0r arm 26, which engages underneath the inclined generating pipe 23, to help support the saine in position.

rfhe discharge arm is disposed in front of the branch generating burner pipe 17, and together therewith project into a box or shield 2T, open at the top and at the outer -end, an@L attached to the rear of the generating burner by screws or bolts 23. The shield 27, is positioned adjacent the open lower end of the carbureting pipe 12, and

Both ends of the generating burner a are closed, and the front surface or wall Secured to the inner endthe end wall of said shield is provided with an opening disposed directly opposite the open end of said carbureting pipe.

Associated with the lower end of the discharge arm 22, and projecting` longitudinally through the shield Q7, is a needle valve mechanism for controlling the flow of heated Va-porized oil from the generating pipe 23, into the carbureting pipe 12. rlhe Valve mechanism embraces a short pipe or tube 29, integrally formed at right angles to the lower portion of the discharge arm 22, or projecting` therethrough, with the internally threaded passage 30, thereof communicating with the passage 31, of said discharge arm. The outer and inner ends of said Valve tube 29, are externally threaded. Adjustably threaded within the passage 30, is a threaded shank or screw portion 32, haring integrally formed on one end thereof an actuating roc 33, which projects outwardly through an apertured cap 34, removably threaded upon the externally threaded outer end of the valve tube 29. Disposed within the cap 3l, is a packing 35, and a washer 3G, adapted to afford a tight joint around the valve rod 33. The outer end of the ralye rod 33, is squared as denoted by the reference numeral 37, to permit a wrench or other suitable tool to be applied thereto to rotate the Valve rod. lntegrally formed on the other end of the threaded shank 32, is a valve stein 33, of reduced diameter, which projects longitudinally through the passage 30, and has the outer or projecting end thereof reduced and chainfered on one side only as denoted by the reference numeral 39, to form a needle valve point 4 0. The chainfered needle valve point 40, adj ustably projects through an outlet opening formed centrally in a nut cap 4:1, which is removably threaded on the inner end of the valve tube Q9, and has a cylindrical portion 4t2, thereof projecting through the opening provided for the purpose in the end wall of the shield 27. The valve needle 40, is chainfered or beveled to afford a means for regulating the valve outlet, by rotation of the ralve rod To start the process of oil-gas generation a starting burner is positioned below the generating pipe 23. The starting burner comprises an open trough gt3, supported at one end by a bracket 44, attached to the bottoni of the generating burner 16. The other end ot the trough e3, is attached to the bracket arin 2G. A wick 45, is placed longitudinally within the open trough 43, and is saturated with kerosene or any other suitable oil from below by means of an under feed neck or sleeve 4G, which projects outwardly from the central front portion of the trough. 'l1 he outer open end of the under feed sleeve 4G, is removably plugged or closed by a screw et?, to permit cleaning of the passage leading into the trough. A vertical priming or feed pipe a8, is threaded into an opening pro- `vided in the top of the sleeve a6, to permit small quantities of kerosene oil to be poured therein. The oil entering the pipe 48, of course flows through the passage in the sleeve 4G, and into the lower portion of the trough to saturate the wick 45, from below.

The operation is as follows:

To start the process` of oil-gas generation kerosene oil or alcohol is poured into the iniming pipo 48, and liows through the sleeve 4:6, into the trough 41:3, of the starting burner to saturate the wick 45. rllhe saturated wick is lighted and the heat resulting from the burning wick acts to rapidly heat the generating pipe 23, disposed above the starting burner. Kerosene or any other suitable hydro-carbon fuel is supplied to the inclined generating pipe 23, through the main supply pipe 25, and the intake arm 2li. ils clearly shown the ,generating or Vaporizing pipe 28, is inclined downwardly toward its inlet end, thereby preventing any impurities, foreign matter or carbon contained in the oil from entering the device. As the intake arm 2li, fills with kerosene small quantities thereof gradually flow into the heated pipe 23, the heat from the starting burner acting to vaporize the oil to form a gas which passes through the generating pipe 23, and the discharge arm 22, into the passage 30, of the valve mechanism. The valve rod 33, is rotated to retract or draw the valve stem 3S, inwardly, thereby causing the chainfered valve needle 4i-O, to also move inwardly to open the valve outlet in the cap end 42, permitting the vaporized oil to pass outwardly.

The draft caused by the air flowing into the carbureting tube l2, and upwardly through the casings 7 and l, acts to draw the escaping vaporized oil from the valve mechanism. into the carbureting tube. The an: in the tube 12, isv thus carbureted with the vaporized oil to' form an oil-gas, which, of course, flows through the opening 8, into the auxiliary casing 7, and upwardly through the opening l0, into the casing l. The oil-gas from the casing l, is permitted to escape through the cooking burner apertures 5. The escaping oil-gas is lighted and furnishes a very hot flame suitable for cooking purposes. Some of the generated eil-gas from the casing l, flows through the opening Q, into the generating burner lf3-17, and out through the apertures 1S and 19. rlhe escaping oil-gas from the generating burner is lighted and the resulting flames engage the generating pipe 23 and the discharge arm 22, thereof, as well as the valve mechanism disposed within the shield 27, which acts to direct the llames from the burner apertures 19, around the valve tube 29, to heat the valve parts to prevent the vaporized oil therein from cooling before it is mixed with air in the carbureting tube l2. The process of oil-gas" generation is thus continued, after once being started by the starting burner, which of course goes out after the kerosene with which the wick 45, is saturated has burned up.

lVhen it is desired to shut off the burner the supply of oil from the tube 25, is closed by any suitable valve positioned in the .main feed pipe. rlhe cooking burners and the generating burner are then allowed to burn until all of the oil-gas fuel in the casings 7 and l, as used up.

The inclined position of the generating pipe Q3, acts to prevent carbonization of the various parts of the generator and burner, and further permits any impurities which may have collected in the lower portion of the intake arm 24, to be drawn olf by removing the closure nut 49, which connects the tubes 25, to the arm 2i. The under feed arrangement of the starting burner permits additional quantities of primingl oil to be poured into the pipe 18, while the wick 45, is burning, in case the device does not get properly started by a single saturation of the wick. The pouring of oil on top of the wick e5, when the same is burning of course is very dangerous, and the under feed arrangement affords a safe means for properly starting the process of oil-gas generation.

The removal of the valve caps 34 and 41, permits proper cleaning of the valve mechanism. The sleeve 46, of the starting burner may also be cleaned by removing the screw al?.

I am aware that numerous details of construction may loe varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
