  • End construction with hollow beam construction for a drum
    Patent number: 4951833
    Abstract: A barrel or drum, preferably of fibre, with metal chimes responsive to longitudinal compressive forces is provided. The compressive forces urge a diagonal flange of the chimes towards the horizontal thereby expanding the outer circumference of the flange of the chime. The outer circumference of the flange of the chime has a rectangular high strength hollow beam construction so as to increase the stiffness or "stretch resistance" of the flange.
