ABSTRACT:
A piston rod, having a threaded end, is threadedly received in a split collar which is (a) internally threaded and (b) externally tapered. The collar is received in a tapered bore formed in a cross-head. The crosshead has a plurality of threaded holes formed therein to receive studs which penetrate a pressure plate. Nuts secured to ends of the studs draw the plate against the collar to cause its threads to fully engage the threads of the rod end, and secure the collar in place. The rod, of course, can be turned in the collar, threadedly to adjust its axial positioning in the collar.
