    • A bullet trap (1) is provided that connects to a muzzle end (5) of a weapon (3). The bullet trap (1) has a body (11) with a chamber (17) into which a bullet can be fired. The chamber (17) has a plurality of baffles (27) located one behind the other in an aligned series arrangement. The baffles (27) absorb kinetic energy of a fired bullet and enable the bullet to be trapped within the body (11). The baffles (27) have a thickness at a center of axis of travel of a bullet less than the thickness at a radially outwardly distant position to provide for a deformation at the center of a first of a series of baffles (27) before there will be engagement of a center of second and subsequent baffles (27).

    • Cymbal drum (10) includes a drum (12) having a plurality of openings (22) for receiving portions of a pair of cymbals (24) of cymbal assemblies (14), which cymbals (24) are adapted to clash together in response to the beating of the drum (12). The cymbals (24) are slidably mounted on a spindle (26) and separated by a compression spring (52). The level of the force used to beat the drum which is required to cause the cymbals to clash together may be selectively altered by varying the engagement of wing nut (48) with spindle (26). The nominal relative face-to-face alignment of the cymbals (24) may be selectively changed and the nominal relative tilting orientation of the two cymbals (24) may be selectively altered to vary the tones produced by the cymbal drum (10) of the present invention.
    • 钹鼓(10)包括具有多个开口(22)的滚筒(12),用于接纳钹组件(14)的一对钹(24)的一部分,钹(24)响应于 滚筒(12)的打击。 钹(24)可滑动地安装在心轴(26)上并由压缩弹簧(52)分开。 通过改变翼形螺母(48)与主轴(26)的接合,可以选择性地改变用于击打鼓的力,以使钹碰撞在一起。 可以选择性地改变钹(24)的标称相对面对准对准,并且可以选择性地改变两个钹(24)的标称相对倾斜取向以改变由钹鼓(10)产生的音调 本发明。
