ABSTRACT:
A power drive yoke adapted for quick attachment to and disconnection from an output drive shaft of a power drive means comprises a yoke having a hub formed thereon. The hub has a centrally disposed longitudinally extending bore for accepting a portion of the output drive shaft. The output drive shaft is mechanically interconnected to the yoke to rotationally drive the yoke by passing means. An annular groove is provided on the portion of the output shaft and is accepted within the bore in the hub. The hub is provided with at least two generally parallel bores each tangentially intersecting the bore on its opposite sides. A locking pin is slidably disposed in each of the parallel bores and has a locking surface thereon to engage the annular groove on the output shaft. Means are provided to connect each of the locking pins to substantially simultaneously slidably move the locking pins within the bores into engagement and disengagement with the output shaft at its annular groove.
