  • Patent number: 6043419
    Abstract: A drum includes a drum shell, a drum head, a counter-hoop and a shell hoop. A drum skin extends over the open end of the drum shell and has a circumferential bead. The counter-hoop has a downwardly and outwardly extending flange which bears on the bead. The shell hoop has a rim which extends upwardly and outwardly. An adjustable clamp ring engages the flange of the counter-hoop and the rim of the shell hoop through correspondingly inclined portions. The clamp ring has a breach and a tightening mechanism so that when the clamp ring is tightened, the counter-hoop is forced downwards, thereby tightening the skin.
