. Railway age gazette . at allcurves on the same track system have the same radius for a carbonizing furnace.

September. 1914 RAILWAY AGE GAZETTE, MECHANICAL EDITION 493 A complete plant consisting of a carbon gas producer andtwo furnaces is shown in the illustration. The furnaces aresupported by trunnions; and the pipe connections to the furnaceand retort, together with the chain and sprockets by means ofwhich the retort is revolved, are so arranged that the furnacemay be tilted for convenience in filling and emptying withoutdisconnecting the pipes or the driving mechanism. The generator supplies gas made up of carbon vapor derived. Sectional Vie>A/ Through Carbonizing Furnace fqom refined petroleum and a neutral gas, combined in suchproportions that the absorption of carbon by the work will takeplace without the formation of obstructing carbon deposits. Eachgenerator has a capacity sufficient to supply two machines ofthe type illustrated. In many cases it is to use gas as the carbonizing agent, thus dispensing with length of time than work near the center. Volatile carbon findsits way into slots, holes and cavities into which sufficient solidmaterial to produce the desired penetration could not be is also a saving in time due to the shorter period requiredto heat the volatile carbon retort to the temperature at whichcarbon is absorbed. Each machine of the size shown in the illustration is claimedto require for fuel 400 cu. ft. of illuminating gas, or its heatingequivalent, per hour, carbonizing gas being furnished at a costof about 10 cents p
