    摘要： A musical instrument pneumatic actuator uses valve seats and a vacuum tube which are integral with one of two plastic main body pieces. An anti-warp brace and curved recessed portion are respectively used to minimize warpage and wear on the bellows. A beveled atmospheric port allows easy insertion of a valve piece.

    摘要： A musical instrument is disclosed which is capable of being operated in either of two different ways--through the use of a rotary record member, or through the manual manipulation of individual keys. The instrument disclosed includes a windchest used to supply air to either of two different principal valves, each of which is capable of being manipulated so as to set up resonance within an associated resonance chamber. Secondary valves are provided for varying the acoustically effective dimensions of the resonating chambers. All of the valves have actuators which extend into an area of the instrument capable of serving as a holder for the record member. When the record member is inserted in this holder and rotated cams on the record member engage the actuators so as to cause the production of a desired series of notes. Keys on the instrument are capable of being manually manipulated so as to cause the movement of levers into engagement with the actuators when no record member is present.
