Rolling mill drive coupling - modified to simplify and speed up changing

摘要

Roll changing on a rolling mill is speeded by a modification to the flat pin, fork-type, coupling. The lower prong of the fork is extended by the addn. of a lug, and the upper prong has a chamber between its inner and end surfaces. The difference in length between the inner faces of the upper and lower prongs is more than half the length of the square coupling block that fits between them.
