Abstract
An apparatus combination for improving the starting mode of a starter for an internal combustion engine is disclosed. The combination comprises a supporting means effective to support the starting motor armature, both for rotary movement about an axis within the field winding and for axial movement in response to the axially directed magnetic forces of the winding. Friction means are employed to sequentially engage each of two conical surfaces carried by the member to be driven by the starter motor, such sequential engagement being in response to the axial movement of the armature. Means are also disclosed to assist the frictional engagement between the conical surfaces of the driven member by use of a resilient ring which allows full metal-to-metal contact between the friction means and driven member, but also provides extended interengagement with the friction means by distortion of the ring along a tangent to the friction means.
