Abstract: A cymbal clamping device used in a high-hat stand including a lock nut, a pair of felt washers for retaining a cymbal, and a clutch nut which are fitted on an attachment fixture mounted at the top end of the high-hat stand. A pair of parallel screw mounting brackets extend from one side of the lock nut so that the space between the screw mounting brackets is reduced when a clamp screw engaging with the screw mounting bracket is tightened so that the elastically deformed lock nut is positionally secured on the high-hat stand without getting loosened.

Abstract: In construction of an upper cymbal fastening assembly in which a felt washer unit holding an upper cymbal is clamped between an upper lock nut unit and a lower clutch nut unit both arranged on a tubular holder inserted over an extension rod, the clutch nut unit is made up of a pair of locally joined sections one of which is elastically deformable toward the other when a vertical force is applied thereto. The elastic deformation brings said pair of sections into firm pressure contact with the tubular holder thereby preventing slacking of the clutch nut unit due to vibrations during performance of the hi-hat cymbal.
