ABSTRACT:
A retainer assembly retains a pair of connecting pins in place within a drawbar arrangement. The connecting pins connect various draft implements to the drawbar and hold the drawbar in a preselected angular position. The retainer assembly provides easy connection of the pins to, or removal from, the drawbar while maintaining the pins in a secured working position. The retainer assembly includes a retainer plate which is spring loaded and is easily manipulated from a first position in which the pins are covered and constrained, and a second position in which the pins are vertically unconstrained. Previous pin retainers for drawbar arrangements used various means to lock or retain a pin in a coupled position, including keys, detents, screw threads, etc. Such previous pin retainers were cumbersome and generally required considerable time and effort to unlock and remove the pin. A worker generally needed to use two hands to couple or release the locking pins. The retainer assembly of the present invention is of simple construction and can be placed in a pin retained position and a pin non-retained position by a worker using a single hand.
