APPARATUS FOR THE MANUFACTURE OF GAS.

SPECIFICATION forming part of Letters Patent No. 355,331, dated January 4, 1887.

To aZZ whom it may concern:

Be it known that I, WILLIAM F. M. Mo- OARTY, a citizen of the United States, residing at Philadelphia, in the county ot' Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Appa-` ratus for thellanufactnre of Gas, of which the following is aspecication, reference being had therein to the accompanying drawings.

ro My invention relates to certain improvements in apparatus for the manufacture of water-gas.

My invention consists, essentially, in the construction of the furnace and retorts, both of i5 which are built up of fire-brick, lined with fireclay, the retorts being supported in the furnace by tiebraces suitably secured or built' in the walls of the same.

Theforni and arrangement of the furnace 2o and retorts may be varied indefinitely to suit the requirements of various conditions; but in order to clearly explain the nature and scope of my invention, reference is made to the accompanying drawings, sh owing one form of apparatus by means of which myinvention may be practiced. y

In the said drawings, Figure l represents a vertical sectional view of a furnace, showing the retorts located therein, with portions 3o broken away to expose the interior. Fig. 2

represents a top view of the retorts and furnace, showing the induction, eduction, and connecting-pipes of the retorts, and the respective valves of said pipes; and Fig. 3 represents a horizontal sectional view of the furnace and retorts.

The letter A indicates a furnace which, in the present instance, is represented as cylindrical in shape, and B is the door entering the 4o lower part ofthe furnace, through whichthe contents ot' the retorts may be removed.

Gis the smoke-escape ilu'e, which leads to a suitable chimney or stack.

The letters D D DZ D3 indicate a series of retorts which. are constructed of fire-brick, built up in sections, which are tongued and grooved together, as shown, located in the in- 'y terior of the furnace, and are lined with fireclay or other refractory material. The upper 5o ends of the retorts are formed with flanged tops Application filed December 11, 1885. Serial No. 185,379. (Nomodehl having man-holes, which are closed by the covers E, held on in any suitable manner, so as to forma tight joint, but permit the retorts to be readily opened for charging. The lower ends of the retorts are provided with pivoted dropbottoms G, which may be let down when required, so as to open the lower ends or" the retorts and discharge the contents of the same when exhausted or otherwise rendered useless. The upper portions of the retorts are built in 6o the crown of the furnace, as shown in Fig. 1 of thedrawings, and at suitable points below are braced by cross-ties H, which are secured or built into the sidewalls of the furnace, so as to securely hold the retorts in avertieal position.

The induction-pipe I enters the lower part of the retort D. The said retort connects at its top with the upper part ofthe retort D. The said retort D connects at its bottoni with the lowerlpart of the retort D2, and the retort D'2 at its topl with the retort D, by means of the pipes d d d2.

The letter K indicates the eduction-pipe leading to vthe main or gas holder. rIhe retorts D and D3 are connected at the top by the pipe d3, and the retorts D and D2 by apipe,d*, which are provided with valves, for the pur-- pose hereinafter more fully explained.

.The retort D is charged with broken stone, so lire-tiles, nre-brick, or any other similar radiating material for the purpose of superheating the steam and gases which are passed into said retort during the process of manufacturt ing the permanent gas. The retort-s Dl and D2 85 are filled with iron scrap to decompose the superheated steam, and the retort D3 receives the hydrocarbon, which may be either liquid or solid, and .charged into the same in the form of spray, vapor, or gas to enrich the 9c gases passing 'from the retort D' previous to the formation of the resultant illuminatinggas. rPhe steam in passing into the 4retort D is superheated, as above stated, in the retorts D D, which are heated to acherry-red heat. It is deoxidized, liberating pure hydrogen gas and an oxide of iron represented by the formula Fe3 0,. Thehydrogen passes onto theretort D3, where it meets with the carbon, either solid or liquid, in the form of benzine, prefroc erably volatilized, in contact with heat or by evaporation by a current of air or heated gas, the whole being converted into a permanent gas in said retort D3 by passing into intimate Contact with the heated material, which may be dre-brick, tile, pumice-stone, or other similarsubstance with which said retort is charged.

When natural gas is employed in conjunction with the other materials for the production of a permanent heating or illuminating gas, the retort D is charged with charcoal, coke, or other suitable solid carbon, and in conjunction with the steam and natural gas in said retort are formed carbonio oxideA OO) and carbureted hydrogen. The gases are then run into the retort D2, the iron taking up the oxygen of the carbonic oxide, setting free the carbon which is taken up lby the gas, which is still further carbureted in the retort D3, if necessary, by means of a suitable liquid hydrocarbon in the form of spray, or in a gaseous condition, the gases being finally fixed in this retort and converted into a permanent illuminating-gas.

If the compound gas is to be used as a heating agent simply, the final carbureting may be omitted, and the gas for heating the furnace for the manufacture of illun1inating`= gas is preferably employed before such carbureting.

The furnace is heated by means of a series of ries of four retorts are employed; but it is evident that they may be decreased or increased in number, ortheir form or position changed, Without altering the character of my invention.

Having thus described my invention, what I claim, and desire to secu re by Letters Patent,

l. The combination, in an apparatus for the manufacture of gas, of a furnace and a series of retorts built up of fire-brick and lined with lire-clay or other refractory impervious material, substantially as specified.

2. The combination, in an apparatus for the manufacture of gas, of a furnace and a series of retorts built up of fire-brick. lined with lireclay or other refractory material, and the brace-ties whereby the retorts are braced and supported, substantially as described.

In testimony WhereofI affix my signature in presence of two Witnesses.
