ABSTRACT:
Two opposing, interactive, and flexible force fields, formed by a flexible, suspension belt, exist within a sphere on opposite sides of it's equatorial plane and are engaged with a cylindrical musical drum by stretching parts of said belt away from the inner wall of an annular frame, to which it is attached, attachment points occurring in the before mentioned equatorial plane, and further into their respective semi-spheres existing on both sides of said plane. A cylindrical musical drum is placed inside the annular frame in such a way that the curved cylindrical shell of the drum exists in both semi-spheres simultaneously and is in parallel relation with the curved wall of the annular frame. The attached belt is stretched and engages a drum circumferentially at a plurality of points on the outer body of the drum near lugs which are attached to it's cylindrical shell. Force created by the attached belt in each semi-sphere pulls the portion of the drum existing therein toward the before mentioned equatorial plane thus toward equal force in an opposite direction from the opposing semi-sphere. A cylindrical musical drum so placed into and engaged with this counterpoise is suspended therein and thereby in a state of equilibrium. The annular frame, with a drum mounted therein, is engaged and/or disengaged with a mounting clamp, which is designed to receive said frame, and which attaches to, or is an integral part of, an external support structure such as a stand or mounting arm.
