Abstract
Difficulty in disconnecting two coupled shafts (38, 40) is avoided through the use of a retractable shaft coupler which includes a sleeve (22) which can engage respective shafts (38, 40) at each of its ends and having at least one spring (28) coaxially positioned inside of the sleeve (22). The spring (28) is sandwiched and contained inside of the sleeve (22) by washers (24, 26) which are retained by splines (32, 34). The construct allows retraction from one of the shafts (40) by moving the tubular member (22) in the axial direction away from the shaft (40) against the bias of the spring 28.
