Thelgasesiwhich pass from the generator retain' their heat as they pass through the pipe 11 into the furnace 12. The furnace is provided with the conical portion 15, saidgconical portion andthe "entire furnace being surrounded with a water jacket 16 which-communicates with a boiler 17 in which the steam is generated. the furnace 12 being provided witha commingling grille 18. p

The injector andenter-the furnace, the air or steam thus being introduced at the mouth of the-same.

The grille 1S which is disposed near the end ;wall of the furnace consistsof tile pipes 27 which are disposed end to end as shown in -:Fig.. 8, the Lpipesbeing so disposed that the -op'ening in the first set'of'pipes' do, not exactly aline with the opening 'in the second set of pipes. It will be noted t-liat this con struction provides an efiicient" grille for breaking up the 'gases of coiilblistion.

pipes'24 pass through the water jacket 16 The end wa'll'of the furnace is connected 7 to the drum 34.- by a pipe 30; saiddrum 34.-

being connected to a drum 31 by the curved:

pipes 32 which extend vertically within the boiler. The drum 31 is connected by a Series of pipes with the cylinder or drum 29 which is supported zit-either end by the boiler casing, a drain pipe 35 extending from the drum 29., This drain pipe is provided .with a valve 36 which is controlled by-the stem 37, the gear '38 on said ste1nmeshing with a gear 39 arranged on the 7 is a e n on the lin -7 f F valve stem 40. Y I v The gas is admitted through the pipe 11 retaining its heat of gcnerationas it passes .intothe furnace, being supplied as it .en

conles'heated to the high state of ircandes- I cen ce after the furnace is in operation. As the gases and air properly mixed. pass into the furnace the mass is ignited by the electric sparkers 4-1.- Itwill be noted that this sparking'of the gases will-be unnecessary after the lining of the furnace has been sufficiently heated, the sparking being discontinned and the gases being ignited by the refract'ory material which is in a state 01 511- candcsccnce. the spark being nit-rely utilized un il the furnace is well heated. The 1 nitcd gases pass through the tile grille dispo sed adjacent the :end of the furnaceand 1 through the pipe 32 to the drum 34i'dis posed withinjthe boiler 17. This passingof;:- the gases through the grille and through the pipe 32 "which constitutes the cooling co lsfan'd which connects't-he retort 3.4 with the retort 31 assuring a thorough mixture of the gases and oxygen under the most favorable conditions conducive to complete rising in'theboiler' 1'6.

;pl ete combu'st combustion, the combustion beingpractt,

.The. products of combustion which pa throughthev cooling coils and desce'n'd the drum 29 pass upward throu h-tliepi 43. The coal tar and. other resi ue passin out;through the drain 35, the. gas fircingij" the tar dshi in' as the valve which is provided with a valve 44'. This? valve 44 consists; of the spherical nozzle 45;"; the topof which is perforated. A valve 465- is arrangeditvithin said nozzle, said valve:

seating itself iu'pfon said valve seat 47 which;

surrounds the 'openingin the nozzle whichi.

' communicates with the pipe 43 'thus clo's i ing the pipe 43. lien the pressure of the-. gas in .t cylinder 01' retort 34 egiceeds the? pressure ofi e water within the boiler 17,

the valve 464%31 open and the gases will? pass into the water, passing through thesame and qommingling with the steam, the resultant mixture being that of a dry permanent gas, saturated with vaporof high specific, and atent heat, this mixture being more valuable in the conversion of heat enorgy to mechanical, than if the gases were expandedindependently.

Attention iis called, to the peculiar-ar rangem the air or steam injectonthe I relief valve 19 accurately regulatinm the pressure admitted to the furnace. 'le

- the structure sli'ownin Fig. l-has been found eflicient, attention is called to the. fact :that

various changes may be resorted to and itthe same result secured. '1

In the modified form shown in Fig. 4-, "the furnace is designed: to receive-oil, convert the same into gas, and ignite the gasthus formed to heat the water in the surrounding jackets. In this form the'furnace is provided with a suitable oil spray 61,-air

- being admitted in any convenient manner.

Arranged within the mace adjacent the -form a perfect mixture.

this form of the device differs from the precil; inlet is a bafile'wall 62, the oilbeing projected against the curved face 63 of said fwa'll, this contact with the WalLIbreaking up the oil and comminglcd steam or air to As before stated frred form only in the fact that the gas is produced in a different way.
