ABSTRACT:
Apparatus for connecting one shaft to another shaft wherein one of the shafts to be coupled has a plurality of splines or grooves around the periphery thereof, an intermediate portion of the spline 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 pin extends through a hole in the housing and the pin is linked to the sleeve, whereby movement of the pin effects rotary movement of the sleeve. The pin, and thereby the sleeve, is biased to a first position, whereby the splines and grooves of the sleeve are misaligned with the splines and grooves of the opening in the housing. The pin is movable by overcoming the bias of the spring to thereby move the sleeve to a position whereby the splines and grooves thereon are aligned with the splines and grooves around the periphery of the opening in the housing.
