T-5841 DEVICE FOR COUPLING AND UNCOUPLING A UNIVERSAL JOINT SHAFT ABSTRACT OF THE DISCLOSURE A universal joint shaft and a power take-off shaft, particularly between an agricultural implement and a tractor, may be coupled and uncoupled by a device which includes a coupling sleeve adapted to be axially locked and unlocked relative to the power take-off shaft by operation of a control ring which is moved in generally parallel relationship with the power take-off shaft between a first and a second position. The coupling sleeve is locked in axial engagement with the power take-off shaft by a spring device which, when engaged by the control ring when the control ring is moved to its second position operates to unlock the coupling sleeve from the power take-off shaft. The control ring is pivotally mounted and is subjected to the force of an over-center snap spring which maintains the control ring in its first or second position under a spring-biasing force, with the control ring when in its first position being out of engagement with the locking spring device.
