Abstract: Apparatus for mounting a cymbal on the threaded end of a cymbal stand. A cylindrical fitting made of resilient material having embedded in its lower end an internally threaded plug adapted to fit onto the threaded end of the cymbal stand and having at its upper end an externally threaded shaft. A shouldered plastic washer designed to fit snugly around the fitting's threaded shaft, the shoulder of the washer sized to fit within the hole in the cymbal to be mounted on the cymbal stand. A knob having an internally threaded hole and a substantially flat lower face surrounding the hole designed to be screwed down upon the shaft of the fitting.

Abstract: A drum hoop for a musical drum, at times referred to as a "counter hoop," which hoop includes a reinforcing channel member and a reinforcing rim. The drum counter hoop retains a drum head with an associated locking member, or ring, by fastening lugs or the like secured to the drum shell and by suitable fastening means such as threaded bolts with nut-type heads thereon, sometimes referred to as tension screws, or rods, which engage with the hoop. The lugs are internally threaded or provided with extensions for threads to engage with the bolts. The drum hoop and drum shell are, therefore, provided with means for adjusting or changing the tension of the drum head by tightening or loosening the bolts which changes the position of the hoop and the drum head locking member with respect to the drum shell. The reinforced construction permits the drum head to be provided with a very high tension without bending or breaking the drum hoop.

Abstract: A swivel hook assembly for use primarily for attaching musical instruments, such as a drum or a pair of drums or other percussion instruments, to the torso of a person, so that the person has both hands free to grasp drumsticks or mallets to play the instruments, particularly when marching. The entire assembly is preferably formed from stamped metal parts and is provided with a slot forming member through which a carrying strap or harness may pass, which slot forming member is provided with a pair of openings at its extremities for the reception of hooks usually attached to straps surrounding the torso of the person playing the instruments. A strap extending across at least one of the shoulders of the person passes or is looped through the slot to properly position the assembly.

Abstract: A musical drum consisting of a generally cylindrical drum shell having openings at its upper and lower ends with a vibratable drum head covering at least the upper opening and a sound projector positioned below the lower opening, which sound projector is substantially a semi-hemisphere with an upper opening therein disposed adjacent the lower opening in the drum shell and with a horizontal opening therein facing in a direction substantially perpendicular to the openings in the drum shell. The half hemisphere sound projector may extend beyond the vertical center line of the shell and may be detachably secured to the shell and may be adjustable radially 360.degree. with respect thereto.
