ABSTRACT:
This invention pertains to an automatically-closing coupling which is adaptable to permit either roundended or square-ended shafts to be laterally inserted thereinto. Pedestals, including anti-function bearing rotatably support driving and driven spindles. Lateral slots are provided in the pedestals, in intermediate locking sleeves and in the spindles into which the ends of a shaft are freely received when the slots are all rotated into alignment and held by a detent means. After the shaft is inserted, a quarter turn of the spindle causes relative rotation between the spindles and the sleeves, locks the shaft in the spindles and releases the detent means, thus allowing free rotation of the shaft and spindles relative to the pedestals.
