Abstract
A clapper assembly includes circular strikers which can be individually rotated so that a new portion of the surface of the striker is presented in the direction of the clapper stroke. A pair of opposing plates located at the end of the clapper bar retain circular, donut-shaped striking elements. Each striker is secured between the plates by a retaining screw through the axis of the striking element. By loosening the screws, the individual strikers may be rotated. Thus, when a portion of the striker becomes worn, it may be loosened and manually rotated to a new position so that a fresh unused area is presented. In addition, the entire clapper assembly may be rotated so that strikers of different compressibility can be interchanged.
