Each of the first gear segments has a peripheral ring provided with radially outwardly extending teeth. Each of the second gear segments is contained within the peripheral ring of a first gear segment and is provided with a peripheral ring having radially inwardly extending teeth to form a compact apparatus for manipulating the bucket.
