in said drawings the portions marked A represent the casing,

and D the center splash shield. l

The casing A is of a common type of'construction, hai/'ing an inc'losed crank casing in its lower end and the engine cylinders eX- tending vertically Lbove said inclosed crank v casing. The ends of the crank casing are formed boredout and. closed with heads 11 `and l2 respectively,`n which4 are formed'f1- bearings for' theends of thecrank-'shaft` 13,??
