ABSTRACT:
Apparatus for connecting one shaft to another shaft wherein one of the shafts has a plurality of splines or grooves around the periphery thereof, an intermediate portion of the splined shaft having the splines removed. A housing is adapted to be connected to the other shaft of the coupling and has a central opening therein with splines and grooves around the periphery thereof to mate with the splines and grooves of the first mentioned shaft. A sleeve, also having complimentary splines and grooves therein, is rotatably received within the interior of the housing adjacent the inner end of the splined and grooved section of the housing opening. A collar is disposed about an outer portion of the housing and is interlocked with the sleeve so that rotary motion of the collar results in a similar rotary motion of the sleeve. A partially circular snap ring member is constructed of spring steel and is also disposed around the housing adjacent the collar. One side of the partially circular member being attached to the collar and another side of the semicircular member being attached to the housing. This semicircular member so attached to the collar and housing serves to bias the splines and grooves on the interior of the housing opening. Rotary movement of the collar in a direction opposing the spring forces of the partially circular member will move the splined sleeve to a position wherein the splines and grooves of the splined sleeve are aligned with the splines and grooves within the opening in the housing.
