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.
A lag assembly for a Kirschner beater comprising a support part for connection to a leg of the spider of the beater and a working part, a plurality of pins projecting from said working part, which pins are so located in said working part that their tips provide a working surface which is convex when viewed tansverse to its length, means adjacent one longitudinal edge of said working part removably, hingedly securing said working part to the said support part and further means adjacent an opposite longitudinal edge for fixedly securing said working part to the adjacent edge of said support part.
A Kirschner beater for a cotton opening machine, the beater being rotatable about an axis and having a plurality of radially extending arms each having a lag assembly on its outer end, said lag assemblies each comprising a support part for connection to a leg of the spider of the beater and a working part, a plurality of pins projecting from said working part, which pins are so located in said working part that their tips provide a working surface which is convex when viewed transverse to its length, means adjacent one longitudinal edge of said working part removably, hingedly securing said working part to the said support part and further means adjacent an opposite longitudinal edge for fixedly securing said working part to the adjacent edge of said support part.
A Kirschner beater for a cotton opening machine, the beater being rotatable about an axis and having a plurality of radially extending arms each having a lag assembly on its outer end, the lag assemblies being secured to the arms and including a support part and a working part, the working part having a longitudinally extending pinned surface which is convex transverse to its length, and wherein one longitudinal edge of the working part is removably and hingedly connected to a corresponding edge or the support part, the opposite edges of the two parts being fixedly secured together after they have been brought together by pivoting of the working part about its one end.
