In the operation of the device steamis admitted to the jet-nozzle from thehose and escaping into the discharge-pipe passes out through the same andthe smoke-stack of the boiler-furnacesuch force and speed as to create a par-tial vacuum in the discharge-pipe aroundthe jet-nozzle and the end of the suction is thus created which will drawall soot and other impurities from theflue into and up through the discharge-pipe. The shape of the elbow is suchthat the soot cannot collect therein, andthe fan or wheel on the end of the jet-nozzle will by its rotation serve to breakup the soot and create a current whichwill carry it out through the discharge pipe-Railway Cross-Tie No. 680, LANZ, of Pittsburg, Pa.
