ABSTRACT:
A dynamically variable oscillating adjustment assembly including a frame and a first link means pivotally connected at one end to the frame and an adjustment mechanism positioned intermediate the one end of the first link means and the frame to adjustably position the first link means with respect to the frame. A second link means pivotally connected at one end to the other end of the first link means and pivotally connected at the other end to a first arm of a bell crank pivotally mounted upon the frame. A second arm of the bell crank is operable to oscillate in response to oscillation of the other end of the first link means. An adjustment mechanism may be interposed between the frame and the intermediate pivot of the bell crank such that the position and stroke of the other arm of the bell crank may be selectively adjusted.
