  • Patent number: 4850258
    Abstract: For a snare drum, the drum heads at the ends of the drum body are secured to the drum body by respective drum hoops. The hoop at the beating end of the drum body is attached to the drum body by an odd number of attaching bolts that extend between the hoop and attachment fixtures on the side of the drum body, whereby the tension lines across the beaten drum head do not pass through the center of the drum head, but instead surround and define a polygonal area. The opposite drum head hoop is held by an even number of bolts and attachment fixtures on the drum body, whereby the tension lines on the second drum head pass through the center of the second drum head. A second wire or a plurality of sound wires in the form of a snappy is attached to the drum body and extends across the underside of the opposite drum head.
