Abstract: A drum of the type having first and second drum heads on opposite ends thereof is provided with first and second bearing hoops, each such bearing hoop being associated with a respective one of the first and second drum heads. Each bearing hoop is provided with an annular bearing ring member which communicates with a respectively associated one of the drum heads, and a bearing hoop coupling means, which is affixed to the annular bearing ring member, and has a plurality of through-holes therein. The drum is further provided with first and second counter hoops, each such counter hoop being associated with a respective one of the drum heads, and provided with an annular counter hoop ring member having an annular bearing edge for communicating with an outward side of the annular drum head ring of its associated drum head. Counter hoop coupling means are affixed to the annular counter hoop ring member and are also provided with a plurality of through-holes therein.

Abstract: A holder for a pair of crash cymbals of the type which are generally employed in orchestral performances is constructed to be collapsible for facilitating storage thereof and transportation between engagements of a percussionist. A pair of cymbal holder members, each of which is symmetrical, utilizes a coupling member for joining the cymbal holders to one another. In accordance with the invention, the cymbal holders are rotatably coupled to the coupling member, but fixable at selectable rotational orientations by operation of respectively associated locking devices. Penetration of the locking devices into the cymbal holders, while in a locked state, ensures a secure locking, or fixation, of the cymbal holders, while reducing the need for high thread stress in the coupling member. The locking devices also serve to fix the crash cymbal holder in a folded state which provides the desired advantages of compactness.
