A direct cranking starter drive for an internal combustion engine has a driven member drivably connected to the engine crank shaft and a driving unit drivably connected to the starting motor. A clutch between the driving unit and the driven member is engaged when the engine runs below a running speed for drivably connecting the driving unit to the driven member and is disengaged when the engine runs above the running speed for disconnecting the driving unit from the driven member. Bearings are provided for permitting relative rotation of the driving unit and driven member when the engine is running and the clutch is disengaged.

A starter drive adapted for use with an internal combustion engine and having a starting motor drivably connected thereto, comprising: a driven member drivably connected to the engine crank shaft; a driving unit drivably connected to the starting motor, said driving unit further comprising: a cylindrical driving member coaxially disposed with said engine crank shaft; having a helical thread on a portion of the inside diameter; a driving clutch element disposed within said cylindrical driving member internal diameter for rotation therewith, said driving clutch element having a helical spline on its external diameter and one-way dentyl sawtooth clutch teeth on one face portion; and means for driving said driving clutch element interposed said cylindrical driving member and said driving clutch element, said driving means including a ring member with a helical thread on the outside diameter, said helical thread adapted to communicate with the helical thread on the inside diameter of the cylindrical driving member, said ring member further having a helical thread on the inside diameter, said helical thread adapted to communicate with the helical thread on the outside diameter of the driving clutch element, whereby when a torque is applied to said cylindrical driving member the ring member is moved towards the driven member; a clutch between the driving unit and the driven member; and means for disengaging the clutch when the engine runs above a predetermined speed for disconnecting the driving unit from the driven member and for engaging the clutch when the engine runs below the predetermined speed for drivably connecting the driving unit to the driven member.
