This patent describes a gearshift apparatus for an automobile with an electromagnetic clutch and a transmission operatively connected to the clutch and having four forward gear trains and an output shaft. This apparatus consists of a first synchronizing means for selectively engaging a second speed gear train and a fourth speed gear train respectively with transmission output shaft. The second speed gear train has a gear ratio such that sufficient torque is produced to start the automobile on an ordinary road. Another feature of the apparatus is a second synchronizing means for selectively engaging a first speed gear train and a third speed gear train respectively with the output shaft. The first gear has a gear ratio producing sufficient torque to start the automobile on an uphill and heavy road. A shift lever means for operating the first and second synchronization means is characterized in the patent. This shaft lever is described as being rotated to a first or second plane for the operation of the respective synchronizing means and as being responsive a means elucidated in the patent for holding it in the respective plane for proper operation. The last component of the apparatus described is a gear select means including a select lever specifically operationally engageable with one of the synchronizing means by rotation of the shift lever to the respective plane and an actuating rod connecting it to the proper shift lever for respective synchronization device operation.
