WILLIAM H. GOSS, OF FRANKLIN TG'WNSHEP, SOIEERSET COUNTY, NEW JERSEYJ GAS-GENERATING BURNER.

Application filed February 8, 1926.

This invention relates .to gas-generating burners, and the objects of the improvements are, first, to provide forthe simple and economical casting of the device in a single piece, thereby eliminating a multiplicity or separate parts and providing a stronger, better, and more lasting structure; second, to provide for the prompt and thorough generation of gas by the efficient application of heat on the generator; and third, to prevent flooding of the device and he consequent waste of oil by the automatic control of the oil feed. v

I attain these objects by the structure illustrated in the accompanying drawings wherein V Figure lis a. plan view of the device; Figure 2, a vertical longitudinal section of the same; Figure 3, a cross section on line 3-3 of Figure 1; Figure 4, a cross section on line 4-4 of Figure 1; Figure 5, an enlarged detailed view of the needle valve; and Figure 6, a detailed view in top plan of one end of the gas-generating cylinder, depicting a part of the float valve mechaniSm.

Describing the invention in detail, 1 des ignates the base of the device, which is relatively long and narrow, and provided with a flat bottom in order to rest firmly and easily upon the grate of the stove or furnace in which the device is placed. To further increase the stability of the device, supporting lugs 2 are provided at each corner of the base and project upwardly on opposite sides of the latter. Above the base and in line therewith is a hollow, barrel-shaped cylinder 3 in which gas is generated as hereinafter explained. This gas-generating cylinder is supported at its ends-upon short vertical extensions 1 -l rising from the er;- tremities of the base, as illustrated.

An auxiliary burner 5 extends along one side of the cylinder 3, and substantially in line with the bottom thereof, being joined thereto by the inturned portions 66 wl'iich are slightly inclined with respect to the horizontal, as seen in Figures 3 and at. The base, cylinder, and side burner are preferably cast in one piece and the construction is so designed as to permit this to be easily accomplished, it being found in practice that a casting is more desirable than piping owing to its greater heat-resisting properties and the fact that it will not, therefore, burn out so quickly when sub- Serial No. 86,888.

jected to the intense flame and heat from the burner jets.

Fuel oil from a supply source is conducted by suitable piping to the inlet passage '7 leading inwardly of the vertical base extension t and communicating "with the central passage 8 of the latter. Passage 8 opens outwardly through the base 1 and has its upper terminal. communicating with a large opening 9 provided in one end of the cylinder 3. vided in the opposite end of the cylinder, and threaded plugs 11 and 12 are inserted in the outer ends of the openings to close the same. Opening 9 constitutes the oil inst to cylinder 3 and has a short bottom groove 13 from which the oil from passage 8 is permitted to flow and drip into the cylinder in small quantities at a time. Opening 10 constitutes the gas-outlet of the cylinder and is in communication with the vertical central passage 1a of the base extension 4t, which passage likewise has its bottom opening in the base 1. Extending clear through the base and intersecting passages 8 and 1a is a central longitudinal bore 15 in terrupted at one or more points by vertically disposed burner jets 16 having needle valve control 17. The bottom openings of passages 8 and 1a are closed by plugs 18 and 19, and the terminal ends of the base passage 15 are closed by

plugs

20 and 21. All of these'plugs are removable to permit access to the passages for purpose of cleaning, etc., and in order to prevent the oilt'rom the inletpassage 8 from backing into the base passage, an internal plug 22 is adapted to be screwed or otherwise engaged in the vertical passage 8 just below the inlet "2'.

The side btrner 5 is cast solid in part, as shown at 23, and has the remaining part cored to provide a by-pass from the gas passage let of the base extension at, which.

b-y-pass consists of the intersecting passages 2% and The outer ends of these intersectingpassages are closed by removable plugs 26 and QT. Passage 25 is provided with one or more burner jets 28 having needle valve control 29 and disposed in an inclined plane so as to direct the flame against the bottom and to the opposite side of the gas cylinder. This arrangement is of particular advantage in connection with stoves or furnaces having the fire-box enclosed by a water-jacket, and in placing the improved device in such a stove or furnace,

A similar opening 10 is pro ill) it will be placed with the burner-less side of the gas cylinder disposed against one side of the water-jacket so that the flame from the side burner, after passing beneath the cylinder, will impinge the jacket walls and be thus applied direct to the jacket. Any number of gas burners may, of course, be used, according to the size of the furnace and capacity of the individual burner.

In order that the oil may be quickly and thoroughly converted into gas, only a small quantity at a time is admitted into the gas cylinder, and the feed is regulated in part by a float-controlled valve and in part by the pressure of the generated gas. The valve mechanism consists of 2. long needle valve 30 extending downwardly for a apprcciable distance into the inlet passage 8, and having at its lower end the usual needle point 61 adapted to engage the valve-opening 32 in the valve seat 33. The valve seat is threadedly engaged in the passage 8 just above the inlet 7 and is removable through the bottom opening of the passage when the plugs 18 and 22 are taken out. Valve 3 has a bracket swiveled to its upper end and presenting spaced upstanding arms a and 6 connected by a pin 0 adapted to engage in a slot d formed in one end of rod 34;, from which the valve is suspended. By means of this arrangement, the valve has a tree swinging movement for self-seating purposes as it is loweredonto its seat. 0d 3% extends inwardly of the cylinder for nearly the entire length of the same and is pivoted at 36 to a. plug 87 removably fitted in opening 9 of the cylinder. A. float 38 is suspended from the free end of the rod and normally rests on or very close to the bottom of the cylinder. A plug 39 engaged in opening 10 of the gas cylinder and extending inwardly thereof, has its inner portion bifurcated vertically to provide spaced guide fingers 40+l0 adapted to extend on opposite sides of the free end of the float rod. Top and bottom grooves 4-1 are formed in the body of the plug and communicate with the vertical passage 42 ot' the plug, which passage is in line with the gas pas sage 1-loi the device.

In the operation of the device, the float is adapted to be lifted by the inflow of only av small amount of oil, and the needle valve is adjusted and arranged to close when the float is slightly elevated, the arrangement being such that at no time will the cylinder contain any great amount of oil. The base 1' of the device has its surface grooved to provide a priming pan or trough -l3 and in starting the device this pan is filled with gasoline or other priming material which is ignited to preheat the cylinder. As the cylinder becomes heated and the oil therein gasified, the gas vapors escape through outlets ti and t2 into the gas passage 1% from whence they are conducted to burners l6 and 28. When the level of the oil lowers in the cylinder, due to the vaporization thereof, the float. drops and opens the needle valve 30. The pressure within the cylinder would normally prevent any oil from feeding into the cylinder, but as this pressure is diminished constantly by the escape oi 'as at the burner outlets, the oil is permitted to drip from groove 13 and becomes vaporized as it falls in contact with the heated bottom of the cylinder, against which the flames from the burner jet are directed In the even; of the flames becoming extinguished, with the resultant cooling of the cylinder, and the loss of pressure therein, the flooding of the entire device is prevented by the action of the float, which, upon the entrance of a small quantity of oil in the cylinder, is elevated the slight degree necessary to close the needle valve and shut otl' further flow of the oil.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
