ABSTRACT:
A semi-annular sleeve segment (60) is welded (78) to a drive member (24). Sleeve segment (60) presents abutment surfaces (52, 54) at its ends which upstand from the drive member (24). The abutment surfaces (52, 54) are contiguous inside surface portion (56, 58) of upper clamp parts (30, 32) that are welded to a transverse drive beam (18). The transverse drive beam (18) extends across the drive member (24). Downwardly directed recesses (34) in the upper clamp parts (30, 32) receive upper portions of the drive member (24). Lower clamp parts (36, 38), having upwardly directed recesses (40) are moved upwardly until lower portions of the drive member (24) are within the recesses (40). Bolts (48) are inserted through bolt openings (42) in the lower clamp parts (36, 38) and are then screwed into threaded openings (44) in the upper clamp parts (30, 32). Tightening of the bolts (48) moves the upper and lower clamp parts (30, 32 and 36, 38) together and moves the inner surface portions (56, 58) of the upper clamp parts (30, 32) into positions contiguous the abutment surfaces (52, 54). Movement of the drive member (24) in either direction, will move the leading abutment (52, 54) into driving contact with the contiguous surface (56, 58) on the leading clamp part (30, 32).
