in Fig, 2 and by Fig. 7, maybe hinged about the pintle '29. It is understood that thecylin- V der block may be hinged on each sidefso that the block maybe swung onto either side.

The cylinder block is cast with a suitable said web portion.

combination of a crank shaft having. a centrally'located thin web portion, a flywheel having a central opening and opposed radial slots whereby the said crank shaft can be passed through the said opening and slots in the flywheel to effect an engagement between the said webportion and the said flywheel,

and means for removably securing thefsaid;

recessil formed by the depending walls 42 and 43 of the cylinder. Immediately below I the walls'42 and 43 are thecomplementary walls 44 and 45 of the crank case. The flywheel therefore is separated from the interior of the crank case'and is arrangedtobe lubricated suitable grease cups 46.

The engine is lubricated by the well-known splash system of lubrication. As is well: knownupon ascending or descending a hill,

the oil seeks the lowest level possible; and

this often resultsv in some of the cylinders receiving airinsuflicient supply of oil, depend I so ing upo nwhether the car is ascendingor descending a grade. In order to maintain: the, oil fromcompletely .seeking'the lowest level of the crank case when driving along a grade, I have provided the 'baflles 47 It is obvious that these baflles will maintain. sufficient oil,
