Abstract: A drum construction is provided with a bottom ring having a plurality of projections extending outwardly therefrom at equally spaced locations about the circumference thereof for supporting tubes of proper length according the drum shell depth. The tubes have internal threads on both ends which accept the tension screws for connecting the top and bottom hoops to the ring. A drum shell is clamped between the bottom ring and the top hoop and is completely free of holes and does not have any hardware attached thereto thereby providing only a minimum dampening effect. The shell is located concentrically on the upper surface of the bottom ring by means of shaped washers which are held in place by lock nuts on the tube ends. Auxiliary support brackets may be clamped to adjacent tubes in spaced relation to the shell so as not to adversely affect the tonal characteristics of the shell.

Abstract: An arcuate rim shot segment of plastics material is provided for attachment to a drum adjacent the metal hoop thereof to prevent damage to a wooden drum stick during rim shot. The rim shot segment has a semi-cylindrical cross-sectional configuration with the flat surface thereof adapted to engage and extend above the internal circumferential surface of the drum hoop. Flexible plastic strips of material extend about the arcuate segment in spaced relation and define tabs for securement between the drum hoop and the drum shell.

Abstract: Two sets of cymbals are mounted on two pairs of horizontally extending arms respectively of a support bracket which in turn is adapted to be mounted adjacent the upper end of a conventional hi-hat support stand of the type having a foot pedal operated rod vertically reciprocable within a hollow tube. The lower arms which support the bottom cymbal of each set of cymbals are detachably clamped to the hollow tube and the upper arms which carry the upper cymbal of each set of cymbals are secured to the upper end of the vertically reciprocable rod and guided relative to the lower arms by means of a guide blade secured to the upper arms and complementary guides secured to the lower arms. A spring is connected between the guide blade and the complementary guides for normally biasing the upper arms away from the lower arms.

Abstract: The adjustable drum is comprised of two cylindrical shells which are telescopically arranged for axial adjustment with respect to each other. At least one of the shells is constructed of metal and a separate set of casings for each drum head are provided on each shell. A plurality of spaced apart insulating strips are disposed between the shells which can be adjusted in a stepwise manner relative to each other. Special adapter plate is provided on one of the shells for supporting a conventional snare strainer mechanism.
