1. A power shaft coupling arrangement comprising in combination:

  • a. a shaft disposed between an associated drive means and an associated driven means and adapted to move axially from a coupled position to a decoupled position and vice versa for connecting and disconnecting said drive means and driven means, respectively;

    b. said shaft having a forward portion provided with means to engage to said drive means when in said coupled position so that torque is received by said shaft, and said shaft having an aft portion provided with means to engage to said driven means when in said coupled position so that torque is transferred to said driven means, and c. a shifting mechanism mounted adjacent said shaft provided with an actuating means for coupling and uncoupling of said shaft and a gripping means adapted to grip and to hold said shaft outer surface upon actuation of said actuating means for shifting said shaft coincident to its own axis from a coupled pOsition to an uncoupled position and to move said shaft from said uncoupled position to said coupled position and releasing said gripping means when in said coupled position whereby said engagement means of said forward and aft portion of said shaft portion of said shaft becomes engaged to said drive and driven means respectively.
