The extremely large size of the breather outlet insures etlicient ventilation for the crank case, and the latter is kept so cool in practice that the oil does not become carbonized. Further, there is practically no waste of oil in my system. As the oil is consumed in use. it can be conveniently replaced from time to time by mcrcl folding back the hood 16 and using the ventilator shaft as a filler tube, the oil passing through the strainer 23. The pump forces the oil from the receptacle beneath the crank case into the filtering and cooling tank 58, whence it is forced by the same pump through the pipe 59 into the various com 'iartn'ients of the crank case. The quantity of oil in the cil receptacle can be conveniently ascertained, either by inspection of the sight gage 14 or of the gage 74, which is carried by the tank .18.
