发明名称 Adjustable spring brush
摘要 An adjustable drum beater for playing a percussion device is herein disclosed. The drum beater comprises a handle in which is engaged a threaded ferrule that has attached thereto a brush for striking a percussion device such as a drum. The handle has a longitudinal cavity formed therethrough that is sized to receive the brush. The cavity also has interior threads that reversibly engage the ferrule. By reversing the ferrule in the interior threads of the cavity, the brush may be stored in the handle of the drum beater. A coil spring is positioned circumjacent to the brush and is longitudinally moveable along the brush to modify the sound created by the brush.
