  • Patent number: 4656899
    Abstract: Opposite ends of a silencer band having a plurality of weights attached thereto are coupled together by selective engagement of a clip member and one of the silencer band weights. To effect such engagement, the clip member comprises a connection portion including a pair of first leg members and an interconnecting first bight portion which together define a loop. Instead of being riveted to the silencer band, the clip member is also fixedly attached to another one of the silencer band weights by an attachment portion. The attachment portion includes second and third leg members each extending from one of the end portions of the first leg members and arranged in predetermined spaced apart parallel relation one to another. A fourth leg member reversely depends from the third leg member and defines a second bight portion.
