Alignment coupling for fixed alignment and free swiveling action

摘要

An alignment coupling is shown which is of chain like construction where one pair of set screws passes through the upper link and engages the top of the lower link so as to adjust its alignment and a second pair of set screws passes through the lower link and engages the bottom of the upper link to adjust its alignment. This coupling is used in a free swiveling mode or a fixed alignment mode.
