ABSTRACT:
A bedknife adjustment device includes a double legged bracket which supports a threaded rod, and a compression spring abuts one leg of the bracket for removing play from the linkage at both ends of the threaded rod. A nut positioned between the legs of the bracket can be tightened on the threaded rod for further compressing the compression spring to thereby remove the force of the spring from the linkage to allow the linkage to be easily swung out to a service position.
