Abstract
A spring trip shank assembly with a fixed downstop includes a pivot area with an eccentric mechanism for varying the location of the shank pivot relative to the downstop so that shank position and tool pitch can be adjusted without need to change downstop location. A bushing with an eccentric bore and a keyway receives a threaded bolt with a mating key. A captive nut fastens the assembly in position for the desired shank pitch. Marks located on the mounting bracket and on the bolt head provide an easily readable indication of the selected pivot location so a plurality of the assemblies can be adjusted to the same pitch quickly and easily.
