Abstract
A gear shift mechanism is for a gear mounted on a shaft within the housing of a power transmitting device. A shift rod is mounted through a hole in the housing parallel with the shaft and is capable of axial movement between a first and a second position to cause corresponding movement of the gear. A locking lever is pivotally mounted within a slot in the shift rod and has an extended end capable of extending beyond the interior surface of the shift rod. The locking lever is pivotally biased to cause the extended end to overlie the housing adjacent the hold when the shift rod is in the first position. A camming rod is also mounted within the shift rod and can be moved axially to pivot the locking lever against biasing to release the shift rod during shifting from the first position to the second position.
