The coal isprepared in the usual way common to theolder types of stokers. The general descrip-tion as furnished by the Elvin MechanicalStoker Company, Xcw York, and shown inthe accompanying illustrations, gives indetail the assembling of a complete unit, ism, the shovels being mounted on ver-tical shafts, the lower ends of which carrysegmental bevel gears. These gears aredriven by bevel segments carried on theupper ends of a pair of centrally pivoteddrive arms, the lower ends of whichcarry steel rollers running in the groovesof a double-faced flat cam. The cam isdriven by a worm gear from the mainstoker shaft and revolves in a plane ap-proximately parallel to the usual inclina-tion of the backhead of the boiler. Eachrevolution of the cam completes a cycleof shovel operation; that is, one shovel. SHOWINT, THE OF THE STOKER EQUIPMENT ON THE LOCOMOTIVE. SO far has appeared in two generalclasses, those that are so constructedthat the supply of fuel is delivered abovethe fire, and those that supply the fuelfrom below, generally known as under-feed stokers. In both cases the mech-anism is driven by a small steam en-gine on the boiler backhead. In somecases a coal crusher is placed on thetender to prepare the coal before itreaches the appliances that convey thefuel to the stoker. In others the coal isprepared before it is placed on the to the new design of stoker. which is mounted on the back boiler headand braced to the mud ring by castbrackets. The proportions of the ma-chine and its location on the backheadare shown in one of the drawings. Theone design is adapted to backheads ofvarying slopes by the insertion of fillerblocks of suitable taper
