ABSTRACT:
Apparatus especially useful in internal combustion engines for adjusting the timing and including a shaft having a longitudinal axis and mounted for rotation about said axis with a circular drive member carried by the shaft. An adjustable key assembly is located between the shaft and the drive member for conducting drive forces therebetween while permitting selective relative angular adjustment. The adjustable key assembly includes a key member having a first end pivotally engaged with one of the shaft and drive member and a second end slidably engaged with the other of the shaft and drive member. The second end of the key member and the other of the shaft and drive member include cooperating inclined surfaces for producing relative angular movement between the shaft and the drive member when the key member is selectively pivoted about the first end.
