Patent number: 4851800Abstract: Electrically and manually operable stop controls for a musical instrument such as an organ are disclosed. One embodiment of the stop control is a drawknob carried by an a transfer plate mounted for horizontal motion adjacent a solenoid having an iron core. Vertical hinge members at opposite ends of the solenoid support the transfer plate. A permanent magnet is mounted on each hinge member in general alignment with the iron core, the hinge members being spaced apart sufficiently to insure that only one permanent magnet at a time is adjacent the iron core, to thereby provide a manual magnetic and gravity-operated toggle motion. Application of an electrical direct current of selected polarity to the solenoid permits electrical shifting of the transfer plate. In a further embodiment, the drawknob is secured to a pivotally mounted armature having a cross-member which carries permanent magnets. Solenoids are mounted at opposite ends of the cross-member to provide electrical shifting of the armature.Type: GrantFiled: February 22, 1988Date of Patent: July 25, 1989Inventors: Richard H.

Patent number: 4677892Abstract: An improved striker mechanism for percussion instruments such as chimes, bells, drums, and the like, is disclosed. A clapper is mounted on an armature for motion between a rest position and an impact position. A solenoid-permanent magnet set is provided to hold the clapper in its rest position. Energization of the solenoid by a short electrical drive pulse produces a magnetic field in the solenoid core which repels the permanent magnet and drives the clapper to impact a percussion instrument sound-producing surface. The drive pulse is sufficiently short that it does not impede rebound of the clapper, so that the rebound force cooperates with the magnetic attraction of the permanent magnet to the solenoid to return the clapper to its rest position, substantially without bounce, thereby producing a highly damped clapper motion.Type: GrantFiled: October 1, 1985Date of Patent: July 7, 1987Inventors: Justin Kramer, Richard H.

Patent number: 4488468Abstract: An electronic musical instrument including a compact, portable pedal board and a storage case for the pedal board and for the electronic components of the instrument is disclosed. The pedal board includes shortened foot pedals having a low profile and a very low throw for activating control switches for the electronics, whereby the pedal board can be used in conjunction with a piano or with other instruments. The low throw is obtained through the use of a guide channel mounting arrangement for the pedals and by the use of pressure sensitive switching.The storage case receives and secures the pedal board and also provides a housing for the tone generator, amplifier and other electronics controlled by the pedal board. A control panel door on the end of the storage case is adapted to receive a control panel, and is hinged to the storage case so that it may be swung fully open to expose the control panel. The case may then be positioned on its opposite end to serve as a display stand for the control unit.Type: GrantFiled: June 9, 1981Date of Patent: December 18, 1984Assignee: Richard H.

Patent number: 4361069Abstract: An electronically controlled swell shutter operator for pipe organs includes an electric motor driving a speed reducer whose output is connected to move the shutters of a pipe organ swell chamber, in order to control the volume of sound heard by the listeners. A swell pedal controlled by the organ player operates a first potentiometer and establishes a first voltage of a given polarity, the magnitude of which represents the exact position that the shutters should be in. The output of the speed reducer operates a second potentiometer which establishes a second voltage of a polarity opposite to that of the swell pedal potentiometer, the magnitude of this second voltage being dependent on the position of the swell shutters. A system of integrated circuit comparators compares the above-mentioned first and second voltages to produce an error signal.Type: GrantFiled: September 23, 1980Date of Patent: November 30, 1982Assignee: Richard H. PetersonInventors: Richard H. Peterson, James A. Mornar

Patent number: 4350073Abstract: A hybrid organ is disclosed wherein many of the musical tones comprising the complete musical instrument are produced by wind blown pipes. Other tones are produced by an electronic tone generating system and produced by loudspeakers. The electronic tone generating system is adapted especially for this purpose and includes simplified means for keeping the electronically produced tones in tune with the organ pipes in spite of the fact that the pipes change their pitch with even slight temperature and other atmopsheric changes.Type: GrantFiled: September 23, 1980Date of Patent: September 21, 1982Inventor: Richard H. Peterson

Patent number: 4341145Abstract: An electronically controlled pipe valve magnet is disclosed. The valve magnet is a solenoid which activates a movable armature to open and close the air flow passageway between a pipe organ wind chest and an individual pipe. The pipe valve is electronically operated by means of a control circuit mounted directly on the solenoid by means of a circuit board which is easily accessible and which may be quickly replaced in the event of circuit failure. The electronic control circuit allows the relatively high solenoid currents to be switched by means of a relatively small control signal, thereby reducing the size and weight of the control cable leading from a keyboard console to the numerous pipe valves in a wind chest. The control circuit is economical and safe for use in a wind chest, and, since relatively low control currents are required, a large number of magnets can be operated directly from a single key contact.Type: GrantFiled: September 23, 1980Date of Patent: July 27, 1982Inventor: Richard H. Peterson

Patent number: 4319513Abstract: A motor driven tremolo generator adapted to be connected to the pressure regulating air reservoir for a pipe organ is disclosed. The tremolo generator consists of an elongated housing pivotally mounted at one end with a free end being adapted to produce a reciprocating motion for transmission to the pressure regulator. An electric drive motor is mounted at the first end of the housing near the pivot connection, and is connected to drive a rotatable shaft located at the second, or free end of the housing. An eccentrically mounted weight is carried by the shaft so that rotation of the drive motor causes the weight to cause the free end of the housing to oscillate with respect to the pivot point. At a point generally intermediate the pivotal connection and the location of the shaft carrying the concentric weight is a suitable linking mechanism which connects the housing to the center of the bellows, whereby the reciprocating motion of the housing is transmitted to the bellows.Type: GrantFiled: September 23, 1980Date of Patent: March 16, 1982Inventor: Richard H. Peterson

Patent number: 4303000Abstract: A compact hybrid pipe organ, wherein certain bass notes are electronically produced, and wherein the remaining notes utilize a compact and portable swell box to produce the characteristics pipe organ tones, is disclosed. The swell box is just large enough to encompass a selected number of ranks of organ pipes, the pipes being oriented to have their opening facing toward an open side of the swell box so that the tones are directed outwardly away from the back surface of the box. The open front of the box is selectively closable by means of a plurality of pivotally mounted shutters which rotate under the control of the organist. At least the rear wall of the swell box is covered with a sound-absorbent material to prevent rearwardly-directed sound waves from being reflected in a forward direction, and thus, to prevent the production of standing waves within the swell box. The shutters may be of a non-sound-absorbent material, and thus may be of wood, or in a preferred form, may be glass plates.Type: GrantFiled: August 5, 1980Date of Patent: December 1, 1981Inventor: Richard H. Peterson

Patent number: 4242935Abstract: For generating tones in an electronic musical instrument, there are provided multiple master frequency sources, a different source for each octave, differing in frequency from each other by a factor which differs from two by at least one semitone, each of which is coupled to a respective frequency synthesizer all of which have the same dividing ratios, to divide down the frequency of its master frequency source to pitches of the twelve notes in the intended octave. In one embodiment the sources are separate master clock pulse sources, and in another embodiment a pulse train derived from a single clock pulse source is applied to the frequency synthesizer for the highest octave, and the pulse train applied to each of the other synthesizers is derived from the pulse train supplied to the frequency synthesizer for the next highest octave by dividing the pulse repetition frequency thereof by a factor which differs from two by one or more semitones.Type: GrantFiled: August 25, 1977Date of Patent: January 6, 1981Inventors: Richard H.

Patent number: 4157051Abstract: A stop tablet control system for an organ in which the "on" condition of selected stops is indicated by an illuminated light-emitting diode (L.E.D.) mounted in each stop tablet. The stop tablets are pivotally supported on a tablet rail and spring-biased to assume a neutral position from which they can be momentarily moved up or down against the action of the spring. When a tablet is momentarily pushed down from the neutral position a switch is closed to actuate circuitry which turns on the associated stop and energizes the L.E.D., and when the tablet is momentarily pushed up from the neutral position the associated stop is turned "off" and the L.E.D. extinguished. The system includes control circuitry for providing in a combination stop action mode an indication of what stops are playing.Type: GrantFiled: June 27, 1977Date of Patent: June 5, 1979Inventors: Richard H.
