The conveyor sprocket is driven from injector is caught by the blast thus pro-duced and driven into the furnacethrough the tube. This is an essentialfeature of the device. In order to prop-erly distribute this coal from side toside, a hopper, delivery pipe or injector,turnable in vertical supports or journals,are used and arranged so that the injectornozzle may be made to swing from sideto side of the door opening. This is ef-fected by means of a link, connecting theinjector with a crank pin, at the bottomof a vertical shaft, to which a rotary mo-tion is imparted, so that as the shaft isrotated the discharge pipe is caused toswing from side to side of the dooropening, thus delivering the fuel fromone side to the other of the furnace,imitating hand firing. In order to distribute it evenly fromfront to rear, a deflector, attached to a.

Below the hopper, into which the coalis delivered from the crusher, is an in-jector, which in the present case is shownof globular form, having a tube extend-ing from it directly into the lower partof the door opening. The rear end of the chamber is openfor the admission of air. and centrallywithin it is fixed an injector, throughwhich compressed air or steam may bedelivered by means of a pipe, with aswivel-joint connection to the interior ofthe chamber. The prepared coal falling downthrough the hopper into the chamber or horizontal shaft, the shaft being jour-naled or supported in front of the do
