Abstract: A support system for an acoustic instrument has connecting elements of flexible material extending between and attaching the instrument and a support frame to support and/or balance the weight of the instrument and isolate acoustic frequencies, thereby eliminating deleterious acoustical effects. Embodied exemplarily herein as a support system for a drum, flexible elements extend between and attach the drum head hoop to a circular frame or support that fully or partially encircles the drum. The flexible elements may be made integral with the drum head and/or its head skin.

Abstract: An adjustable drum beater for playing a percussion device is herein disclosed. The drum beater comprises a handle in which is engaged a threaded ferrule that has attached thereto a brush for striking a percussion device such as a drum. The handle has a longitudinal cavity formed therethrough that is sized to receive the brush. The cavity also has interior threads that reversibly engage the ferrule. By reversing the ferrule in the interior threads of the cavity, the brush may be stored in the handle of the drum beater. A coil spring is positioned circumjacent to the brush and is longitudinally moveable along the brush to modify the sound created by the brush.

Abstract: An adjustable camber induced snare assembly for a drum with a hollow body with a batter head and a snare head comprises an elongate snare a support fastenable adjacent to the hollow body extending across the snare head. Opposing adjustable and biased snare fasteners are mountable on the snare support for slightly tensioning and supporting snares. Adjusting the snare fasteners creates a camber in the snares to adjustably urge the snares to continuously have contact with the snare head during drum play without significant tensioning.

Abstract: An improved hi-hat percussion instrument has a treadle stand with a central support shaft with a lower rod therein, the rod and support shaft being connected to a foot pedal. A hi-hat cymbal assembly has a lower fixed cymbal and a movable upper cymbal located above the central shaft. A bias spring is between the cymbals urging the upper movable cymbal away from the lower fixed cymbal. A flexible member is connected to the lower rod and the movable top cymbal which will then bring the two cymbals together by action of the foot pedal. A pivoting knuckle also permits the hi-hat cymbal assembly to assume varied angles.

Abstract: A tunable shell-less, rimless drum utilizes a multiplicity of tuning assemblies positioned about the frame of a pretensioned or untensioned standard drum head. Each tuning assembly engages the frame and avoids tone impairing deformation of the drum membrane during tuning so as to preserve the natural tonal quality of the drum. A pivotably mounted lever at the bottom of the tuning assembly bears against a tuning band which engages the drum membrane, and cooperating notches on tuning band and lever retain the tuning band in a fixed position relative to the frame to prevent pitch variation or binding due to tuning band movement. A threaded rod slides along a slot in the assembly and threadably engages a lock nut positioned within a nut confinement slot to prevent unwanted loosening of the rod. The invention provides a tunable, compact, lightweight, rimless drum which has tuning convenience and tonal quality superior to most large, heavy shell type drums.

Abstract: A bracket for mounting shell-less drums such as roto-toms or pre-tuned heads consists of an arcuate member having inwardly directed flanges which have apertures to mount the lugs of the roto-tom or clamps for clamping the pre-tuned head. The bracket is essentially semi-circular and provides its main support at diametrically opposed points of the drum and utilizes additional fastening points for balancing.

Abstract: A portable drum set is provided by utilizing a pre-tuned head which is clamped to an arcuate member. The arcuate member has a pair of floor-engaging legs on either side which are releasably clamped to the arcuate member. Other percussion instruments such as drums or cymbals may be mounted to the top of the arcuate member or the legs to provide a full kit. Also, a resilient pad is placed on the bottom surface of the bass drum pedal to help isolate the set and vibrations from the supporting surface. The clamps may be formed either of a resilient material such as rubber or may be formed of metal to rigidly clamp the pre-tuned head rim to the arcuate member.

Abstract: A stand for the mounting of floor toms is provided with a circular member having several inwardly directed flanges which engage the lugs of a drum. The circular member has a moderate adjustment as to circumference to provide optimum sound quality. Grommets and springs are utilized in conjunction with the flanges to mount the drum. Several supporting legs are utilized to suspend the circular member above the floor.

Abstract: A stand for mounting floor tom-toms consists of an arcuate member having inwardly directed flanges which have apertures therein for mounting to the lugs of the drum between the castings and the rim. Vibration-absorbing grommets are provided in the flanges in order to provide a resilient support and isolate the stand from the vibration of the drum. Brackets are provided at diametrically opposite parts of the arcuate member for clamping leg members. The stand may be adjusted for both angular and vertical position relative to the leg members.

Abstract: A bracket for mounting drums of the tom-tom type consists of an arcuate member having inwardly directed flanges which have apertures to mount to the pre-existing lugs of the drum. Vibration absorbing grommets are provided in the flanges in order to provide both a resilient support as well as to cut down vibration transfer into the drum stand to which the bracket is mounted. The bracket is essentially semi-circular and provides its main support at diametrically opposed points of the drum and utilizes additional fastening points for balancing.
