Abstract
A lag or stave assembly for a Kirschner beater which replaces the traditional one-piece wooden lags and is preferably formed from extruded aluminium. The lag assembly is formed in two parts with a first support part which is preferably channel-shaped and can be secured to the free end of an arm or spider of the beater, and a second pinned working part removably secured along its leading and trailing edges to the upper ends of the arms of the support part, one edge, preferably the leading edge, of the working part being secured to the support part removably and hingedly, e.g. by a hook-shaped tongue engaging in a mating groove, and the other edge being fixedly secured to the other arm of the support part, e.g. by means of screws and/or any type of snap-fit or interlock. The arrangement preferably ensures that one of the parts is loaded in tension or compression when the two parts are secured together to prevent rattling.
