Application filed July 3, 1909. Serial No. 505,865.

' To all whom it may concern:

Be it known that 1, Earn. N. Psncr, citizen of the United. States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Oil-Gas Apparatus, of which the followin is a specification.

My invention re ates to a means for obtaining gas of that class known as producer gas from the combined action of an incandescent Carboniferous fuel, and a spray or jet of ignited oil directed upon and through said fuel.

It also consists in details which will be more fully explained in the following specification. p

The figure is a vertical sectional view of an oil gas apparatus showing my invention.

My invention is desi ned to first burn the oil or liquid hydrocarbon either wholly or vpartially, and to pass the products of comustion, which accompanying heat, over or through the solid Carboniferous fuel, which may consist of coke, charcoal, or under cer tain conditions, lignite, peat, wood, or anything which will carbonize, and to form layers of incandescent carbon for the prod nets of combustion of the oil to pass through.

- Such a gas is similar to producer gas, WlllCll is evolved from coal considerabl richer.

In carrying out my invention the oil is burned in conjunction with air, and if desired, steam may also be employed.

As shown in the drawing, A is a stack or chamber containing in the lower part a carboniferous fuel 2. At the top of the stack is a closure 3, through the. center of which enters an oil discharge pipe 4. Exterior to this pipe are air and steam inlet pipes, as 5 and 6, and the lower end is made divergent or funnel-shaped, as shown. at 7. Oil being admitted through the inlet pipe is ignited and discharged in a divergent jet or spray, being burned as it passes downwardly, and strikes the top of thecarboniferous fuel which is soon ignited and raised to an incandescent state.

The products of combustion of the oil consist of carbonic acid gas (C0,) and other gases, and these gases pass through the ayers of fuel which is thus rendered incan descent. As the CO, passes through this carbon it takes up another atom of carbon and becomes carbonic oxid (G0) which is gas producers, but is wardly thercinto; and air and steam a combustible gas. If steam be admitted it acts in a well known manner to enrich the gas with free hydrogen and more carbonic oxid, and furthermore, prevents clinker from forming.

If the combustion of the oil is incomplete, the unburned parts will be delivered at a point where the flame impinges,in the form of particles of oil, tar, lampblack, and other heavy constituents. Under the influence of the heat these will all be reduced to lampblack, coke, vapor, gases, and clinker, and tend in a measure to replace the coke which furnishes the additional atom. of carbonto unite with the carbonic acid gas, and oxygen produced by the steam. The gases and products of this operation pass through the fuel bed, coming out at the bottom as permanent gases, clinker, and a small amount of free carbon and condensable vapors. The gas after leavin the apparatus is washed and purified, an is intended primarily for gas engines, furnaces, etc., but may be subjected to special treatment to lit it for illuminating purposes.

This invention may be employed in either a suction or a pressure apparatus. Any suitable provision may be made for feeding the solid fuel without letting in fresh air, and also for removing clinker, ash, and other debris.

Patented at... s, 1910 In the drawing, the closure 3 is in theform of a hopper or container having the lower part convergent to meet the divergent funnel 7. This; container has a removable cover or opening through which it may be charged, and a ate 1n the lower part through which SOlltlfllQl may be admitted into the main chamber A, as required;

Having thus described my inventiomwhat I claim and desire to secure by Letters Patcut is-- An apparatus forunanufacturing gas, said apparatus comprising a retort having a vertical chamber with a gas outlet at the bottom; :1 solid fuel hopper at the-top, having a lower cone-shaped end entering the top of said chamber, said hopper having a central tubular portion whose lower end diverges downwardly; an oil supply pipe passing through said tubular portion of the hopper and adapted to discharge a divergent spray into the top of said chamber and down entering the central tubular portion 0 the pipes hopper and dischar ing in the said divermy hand in the presence of two subscribihg gent portion theme in juxtaposition with witnesses.

the oil supply pipe whereby the steam and p w A;

air may be commiiigled with the spraying EARL E 5 -oil and directed downwardlyinto the cham- Vitnesses:
