Abstract

My invention relates to improved method for a manual gearshift and clutch training apparatus providing for most favorable operator control through the use of sensory indicating devices. A purpose of my invention is to describe apparatus which will serve to teach the correct usage of the manual gearshifter controls as employed on vehicular machines through sensory devices capable of instructing the correct usage thereof to a novice operator. A further purpose of my invention is to provide for the teaching of the correct usage of the manual clutch controls as generally employed on vehicular machines equipped with manual gearshifter. A further purpose of my invention is to provide an attention getting sensory signal in the event of improper operation of the manual clutch. A further purpose of my invention is to provide sensory indication which will serve to tutor the experienced operator such as to effect more efficient operation of the said vehicular machine.
