An improved coupling for driven shafts is formed by juxtaposed bores. A slide core is disposed within the chamber formed by the bores. A plurality of radially extending splines are formed and used to rotatably fasten the core and the shafts. Adjustment means are associated with the core to move the core from an engaged position between and connecting the shafts for rotation to a second disengaged position within one of the bores.

A coupling for transmitting power between two shafts including: a first shaft said first shaft having a first cylindrical bore therein, the bore coaxially aligned within said first shaft, the bore having a plurality of longitudinally extending channels; a second shaft, said second shaft having a second cylindrical bore coaxially aligned within the second shaft and having a plurality of longitudinally extending channels along the bore each channel in the second cylindrical bore having a one to one correspondence to a complimentary channel in the first cylindrical bore and the end of the second shaft containing the second cylindrical bore being juxtaposed the end of said first shaft having the first cylindrical bore; a sliding core adapted for longitudinal motion within a chamber formed by the first and second cylindrical bores, said core having a plurality of radially extending splines disposed about and extending longitudinally along the outer surface of said sliding core, the splines being adapted to engage the channels located within the bore so that when the sliding core bridges the space between the first and second shaft the shafts are coupled together for rotation, said sliding core having a rack formed thereon; an adjustment pin mounted near the periphery of one of the shafts, said pin having its longitudinal axis disposed in a plane perpendicular to the longitudinal axis of the shaft, said pin having a gripping portion extending outward into a recess in said shaft said gripping portion being adapted to be grasped so as to effect rotation of said pin; a pinion gear fixed on said adjustment pin so as to engage the rack on said sliding core so that rotating said pin can move the sliding core from a first coupled portion where the core engages both shafts to couple the shafts so they rotate together to a second uncoupled position where the core is drawn into the shaft containing the pin so the shafts are uncoupled.
