ABSTRACT:
A kettle-shaped drum has an annular recess adjacently below the top end of its hollow body. The flexible drum head includes a peripheral rib disposed in the recess and engaged at the top by a bracket. A plurality of recessed tensioning screws that extend downwardly from the bracket are threaded into a shoulder beneath the recess to permit adjustment of the head tension.
A framework for supporting a drum assembly includes a series of elongate frame members that are interconnected by a plurality of identical joints. Each component of the drum assembly is supported on a rod which is in turn received by a joint mounted on one of the frame members. The construction of the joints permits the frame members to be assembled in any desired arrangement and also permits universal positioning of the drum assembly.
