Automotive industries . tly inthe detachable cylin-der head, and are ac-tuated b y overheadrockers and push , spherical endedfollowers are used;they are set into castiron guides and havecupped upper ends forthe solid push rods,which apply throughcupped extensions tospherical studsscrewed into the un-dersides of the rock-ers. The accompany-ing illustration shows the design of the rockers androcker shaft. The latter is carried in three bearingbrackets and is bored and threaded internally at oneend to receive the union for a connecting pipe to theengine lubrication system. Oil is delivered into thestationary shaft at this end and is led through a counterbore to a deep groove running along the upper surfaceof the shaft. The lubricant then serves for the rockers,not only their pivot bearings, but also their push-rodends, the rockers being drilled to convey oil to a thickfelt washer located around the spherical stud betweenthe rocker and the push-rod cup. May 5, 19-21 AUTOMOTIVE INDUSTRIES THE AUTOMOBILE. (To the Left) —Right side Standard light car engine. (To the Right)—Half front view Standard light car engine with chain cover removed. View shows supplementary water outlet at front end of cylinder head. All moving parts of the overhead valve gear are, there-fore, lubricated under pressure, the excess of oil exudingfrom the rockers finding its way back to the crankcasethrough the space—enclosed by an aluminum cover—upwhich the push rods pass on the left side of the cylinderblock. The latter is an iron casting separate from thecrankcase, which is a three-part unit of aluminum, thelowest section forming an oil sump. The upper sectionof the crankcase is formed with a webbed bracket exten-sion on each side, enabling the engine to be carrieddirectly in the main frame. The crankshaft, having a flange to which the flywheelat the rear end is secured by four bolts, is carried inthree white-metal bearings from the upper half of thecrankcase. It is drilled for
