Specification of Letters Patent.

Patented July 13,1915.

Application filed December 17, 1913. Serial No. 807,262.

To all whom it may concern:

Be it knownthat I, WALTER C. MINNIEAR, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certainnew and useful Improvements in Gas-Generators, of whichthe following is aspecification.

My invention relates to improvements in gas generators, and myprin'cipal object is to provide a simple, inexpensive,apparatus of this character wherein crude oil and water may be quickly and economically generated into gas for heating, lighting and power purposes. I V v One important feature of the invention resides in a combined furnace and retort in which the oil comes into direct contact with the fire, to the end that said oil may be instantly vaporized with a small consumption of fuel. A further advantage in bringing the oil into direct contact with the fire, resides in the fact that the nonvolatile elements are consumed, thereby adding to the fuel and at the same time eliminating impurities from the gas to the end that the latter will not have to be subjected to the usual purifying process.

Another feature of the invention resides in a boiler surrounding the retort, so that heat radiating from the latter generates steam in the former which is conducted to the retort and coming into direct contact with the fire is generated into a fixed watergas which intermixes with the oil-gas.

Other features of the invention will hereinafter appear, and in order that said invention may be fully understood, reference will now be made to the accompanying drawing, in which:

Figure 1 is a plan view of the apparatus. Fig. 2 is a cross section on line II-II of Fig. 8. Fig. 3 is a front elevation of the apparatus. Fig. 4 is a central vertical section on line IVIV of Fig. 1.

1 designates the combined retort and furnace, the lower portion of which is provided with a grate 2 and an ash-pit 3. Beginning at the grate 2, the combined retort and furnace is lined upward a suitable distance with fire-brick 4 to protect its outer shell from burning out. Access is had to the ash-pit 3 through a door 5 and access is had to the grate through a door 6.

7 designates a flue leadingupward from the top of the combined retort and furnace and normally closed by a damper 8, oneend the ash-pit 3, for the purpose of admitting an air-blast when coke or similar fuel is employed, or for admitting fuel gas when coke is not used for fuel purposes.

ll des1gnates an outlet pipe leading from a point just above the grate 2 for conducting the manufactured gas from the combined retort and furnace l. V

The oil to be manufactured into gas is introduced into the top of the combined retort and furnace through feed-pipes 12, and discharged directly upon the fire.

l3 designates the boiler which surrounds the combined retort and furnace l and the lower portion of its flue 7. By surrounding the combined retort and furnace with the boiler 13, the water in the latter is not only economically generated into steam by heat from the former, but also prevents said combined retort and furnace from burning out. Boiler 13 is provided with the customary pressure-gage 14, safety-valve 15, blow-off valves 16, and water-gage 17. Steam from the boiler 13 is conducted to the combined retort and furnace 1, through pipes 18 equipped with valves 19 to control the flow of steam therethrough. Water is admitted to the lower portion of the boiler through an inlet pipe 20.

The upper central portion of the boiler is provided with a water chamber 21 to prevent the flue 7 passing therethrough from burning out.

The operation briefly stated is as follows: Then coke or other fuel is employed for heating purposes, it is thrown into the combined retort and furnace 1, to the proper depth, through the flue 7 and then ignited, the damper 8 being left open for draft purposes. The fire is then fanned to an incandescent heat by an air-blast admitted I through inlet pipe 10, after which the damper 8 is closed. The oil to be vaporized is then admitted through the feed-pipes 12, directly upon the incandescent fire, and instantly converted into an oil-gas which escapes through the outlet pipe 11 into a gasometer or other receptacle, (not shown). While the oil is being generated into gas,

steam is generated in the boiler 13 by heat I radiated from the retort 1, and on attaining V a certain pressure is admitted simultaneously or alternately y'vith 011 to theeombinedl et r and urnace ;i ';i .P@$fl e te;-, the'xoutlet"pipeYfIL' 'i't pa'sses ithrofighthe incandescent fipe'and is ilistantly generated 7 into afixed itter-gas which cemb iri .parent that I haveprodiicede ggts generatef embodying the featuresof advantigeebove enumemed',-= and While 'I havef shown? and e j e desci'ibed the preferred. form ofmj inVeIi' "tion, l ef course egservewhe right to make 1 suchi'chetnges'fin the ceristruction, -combina- I "tid'n', and arr'ahgelhent-ofparts as'properlyTf "fall Within the spirit and scope/of the cltimg T EHaVingthUSdescribedlniy ini entien;What 4 Iclaim and desii'eirtefseeilreby Letters Pat.- --:en't;is:'
