ABSTRACT:
An improved drive system is described for use in coupling a drive means to a driven element. The system includes a novel drive rod with threadedly connected portions which permit an adjustment of the drive rod length with an independent adjustment of a spring loaded coupling for permitting the rod to shorten when the driven member encounters an obstruction which exerts more than a predetermined obstructive force on the drive system. The drive rod is useful, for example, in operating an article transfer machine such as one having an oscillating egg transfer head. The drive rod length adjustment adjusts the end positions of the path of motion of the transfer head. The adjustable spring loaded coupling in the drive rod permits a temporary interruption in the movement of the driven head preventing injury to the operator or damage to the machine where an operator's hand or some other object inadvertently enters the path of the transfer head. Additionally, the spring loaded coupling facilitates egg transfer by permitting the transfer head to engage oversized eggs without excess pressure and accommodates the pick-up action for use at stacks of trays of steadily increasing height.
