Theinventor claimed that still better results could have beenobtained in a specially constructed furnace. The drip fires of Wagenknecht (fig. 4), which weremade in 1870 and 1871 for Dwrient, at Dantzig, for sometorpedo-boats, were chiefly based on Audouins principal feature is really the arrangement of thehearth. The oil flowed out of the pipes into the groovesin the fire-bars, of which there were as many as there were. pipes ; the oil was consumed in these grooves, and air wasblown through the spaces from the unused ashpit, as itwas found that the natural draft was not sufilcient. Thepetroleum was contained in four tanks fitted behind theengine, which were connected by pipes, and a simplepump worked by the engine. At each revolution of theengine a certain [[uantity of petroleum was driven into thecollecting-pipe in front of the fire-box. But notwithstand-ing the fans, the combustion was so imperfect that a con-stant column of thick black smoke came out of the particular trouble was the trickling of the oil out of thefire-bars into the engine-room at each roll of the the fire went out altogether, owing to stoppageof the supply-pipe or other accidents. These torpedo-boats made about knots with petroleum. As thissystem proved to be inefficient, the boilers were alteredand adapted for coal-firing. The drip fire of Kamenski, a variati
