ABSTRACT:
An electric starter for an internal combustion engine has a coaxial pinion drive mechanism for urging the pinion gear into a positively fully meshed arrangement with the flywheel of the internal combustion engine prior to full power application to the cranking motor. The pinion drive mechanism is incompressible throughout its motion. The drive solenoid has a solid plunger which is limited in its stroke corresponding to the fully meshed position of the pinion gear by a pair of electrical contacts which are shorted at full stroke by the plunger functioning as a contact therebetween. The cranking motor is operated at a slow rotation at all times prior to full meshing of the pinion gear to aid in meshing thus reducing tooth wear and gear lash.
