US 11,008,994 B2 · Engine starter attachments for drill/driver gun

Abstract

A specialty nut and specialty ratchet driver device used to start an internal combustion engine, each with an integrated one direction clutch, designed to be an attachment for a commercially available battery operated drill/driver gun. The specialty ratchet driver with an integrated one direction clutch is inserted into the driver receptacle of the socket placed over the nut on the crank shaft of the engine. One end of a drive shaft is inserted into the one direction clutch portion of the specialty ratchet driver device and the other end of the drive shaft is inserted into the chuck of a battery operated drill/driver gun. The torque of the drill/driver gun turns the crank shaft of the engine with sufficient force to initiate starting of the engine. The one direction clutch then allows the engine to turn faster than the drill/driver so as not to impede the engine start up.
