Abstract
A sprocket drum assembly is constituted by two complementary, radially-separable sprocket drum assembly parts. The assembly comprises a hollow, cylindrical drum and a sprocket wheel having an odd number of sprocket teeth. The two assembly parts meet along two surfaces. The inner edges of at least those portions of said surfaces associated with the drum lie in a diametrical plane of the assembly. Each of the outer edges of those portions of said surfaces associated with the sprocket wheel lie between a respective pair of sprocket teeth.
