Abstract: An adjustable pedal unit, for beating a drum, comprising a base; a pedal having rearward connection to the base, at a heel region, to accommodate pedal pivoting; a pedestal unit carried by the base and spaced forwardly of rearward connection, and a drum beater carried by the pedestal unit to be rotated in response to foot actuated pivoting of the pedal; and there being an adjustment on the base whereby the relative positioning as between the pedestal and the pedal can be selectively adjusted.

Abstract: In a percussion instrument actuating assembly, the combination comprising a carrier structure; first and second pedals carried to extend in generally side-by-side relation and to independently pivot; first rotary axle structure operatively connected to the first pedal to be rotated thereby, and having rotary motion output locations spaced apart along the axle structure and via which rotary motion is transmissible to actuate different percussion instruments in response to selected pivoting of the first pedal; and a second axle structure operatively connected to the second pedal to transmit motion for actuating an additional percussion instrument, in response to selected pivoting of the second pedal.

Abstract: A substitute drum, the combination comprising a hollow case to contain equipment for transportation, and removal from the case, the case having a side wall that is relatively stiff, and a support to support the case with a side wall extending in a selected position, during striking motion transmitted to the side wall by a drum beater.

Abstract: Percussion instrument drive apparatus, comprising in combination first and second drives associated with first and second percussion instruments, respectively, and a foot actuated pedal and a pedal driven driver selectively movable to drive one or the other of the first and second drives, as the pedal is actuated, the driver being carried independently of the pedal.

Abstract: A percussion instrument has first and second shells each of which extends away from the other, the shells forming cavities; a closure for one of the shells having a diaphragm portion and closing a portion of the cavity formed by the one shell, the closure spaced from a shell interconnection region; a cavity formed by the other of the shells being open at one end thereof in a direction away from the interconnection region, and loose pellets contained in a portion of the cavity formed by one shell, the pellets freely movable to impact the one shell and diaphragm portion to produce a rattling sound when the instrument is shaken.

Abstract: In a tambourine, the combination comprises a frame extending at least in part along an extended path, multiple jingles carried by the frame at selected locations along the path, and auxiliary plates carried at an auxiliary selected location relative to path and characterized as clashing to produce a different sound than the jingles' sounds when the tambourine frame is impacted near the auxiliary plates.

Abstract: A drum support, comprising in combination at least one leg operatively connected to the drum, and extending below the drum, first and second feet associated with one leg engagable with a support surface, at least one of the feet positioned for adjustable movement relative to the other foot.

Abstract: A drum beating assembly includes a foot operated pedal having inertia weights carried to increase the drum striking force of the drum beater operatively driven by the pedal.

Abstract: A percussion bell support includes a base connected to the bell head end, a jaw swingably attached to the base, surfaces on the base and jaw to clamp to a support member, when the jaw is swung toward the base and head end of the bell, a connector shank passing through the jaw and into the base, and a handle, the jaw remaining between the handle and base during swinging of the jaw and during handle and shank rotation to tighten the jaw and base to the support member.

Abstract: In a percussion instrument arm adapter, the combination comprising a longitudinally extending arm; a first clamp unit carried at one end of the arm, and a second clamp unit carried at the opposite end of the arm; at least one of the units having primary elements including a carrier, a primary clamping plate and a secondary clamping plate, a primary fastener interconnecting the carrier and primary clamping plate to laterally retain the primary clamping plate to the carrier, and allow adjustable rotation of the primary clamping plate relative to the carrier, and a secondary fastener adjustably interconnecting the secondary clamp plate and first clamping plate, the plates defining rod clamping surfaces; and whereby a rod may be carried by an adapter by reception and retention by and between the plates.

Abstract: An apparatus for processing the cylindrical shells of drums, which comprises a cradle sized for reception in embracing relation with the shell, the shell having a longitudinal axis, the cradle having support structure to clamp a cylindrical surface of the shell and at lengthwise locations, for supporting the shell; structure operatively coupled to the cradle to effect displacement of the support structure to clamp the shell surface; structure for rotating the cradle about an axis corresponding to the drum shell axis, thereby to rotate the shell about the axis; and tooling facing the shell to engage and process the shell as it rotates.

Abstract: The method of enabling optimum tuning of a drum having a shell, a head and adjustable tuning members, that includes suspending the drum shell to vibrate when struck; striking the suspended shell to vibrate at a characteristic acoustic frequency; sensing the acoustic frequency and converting the sensed acoustic frequency to a labeling value; and using the value to label the drum to indicate the frequency; whereby a drum user may tune the drum by adjusting the members to cause the drum to resonate at or near the frequency when the head is truck.

Abstract: An apparatus to sand the outer surface of a cylindrical drum shell, the shell defining a first longitudinal axis, and comprising a frame; first structure on the frame to position and rotate the drum about the axis; first structure on the frame, including a belt, for engaging and treating the drum surface during drum rotation; and second structure on the frame to effect pressural engagement of the rotating drum surface with the belt.

Abstract: In a cymbals position control apparatus, the combination comprising a mechanism, including lever, a hook on the lever, and a handle on the lever to lift an upper cymbals disc, and to release the upper disc to drop toward a lower cymbals disc; means including a vertically movable upright rod to support the mechanism; and a bumper on the handle to bump against the rod before the hook can strike the rod, when the lever pivots to release the upper disc.
