The auger looks like the one from the universal bin feed tower. The u-joint linkage enables the elevation angle of the feed tube to be adjusted, and the assembly can be rotated over a wide range, so the feed tube can be positioned almost any way you like. To me, this is one of many convenient features available in the conversion stokers that have been lost in the newer models.
That u-joint linkage should have 2 grooves, one near each end. The life of the linkage can be extended by wrapping the joint loosely with canvas, and holding the canvas in place by tightening a copper wire into each groove. The canvas protects the linkage against direct exposure to coal fines and dust from the feed tube, and retains in the linkage grease injected through the zerk.
