4 Claims.

This invention relates to an improvement in pipe organs, and more particularly to such organs wherein the pipes are arranged in two or more groups, certain at least of which groups of pipes 5 are mounted in acoustically insulated housings,

each housing being provided with one or more microphone and amplifier assemblies by which the sound vibrations are transmitted as electrical vibrations to sound receivers.

Heretofore it has been thought impossible to provide full organ and pedal effects in a pipe organ except by installing a great number of rows of pipes, i. e., stops, a practice which is very expensive and which requires considerable space.

The primary object of this invention is to provide a pipe organ wherein full organ. efiects and/or pedal effects can be obtained without the great expenditure of money and space previously thought essential, such organ comprising, for example, in combination with a group of pipes which speak directly into the auditorium and by which the organist can produce a suitable variety of tone colors, which group forms the solo organ, one or more groups of stops acoustically insulated and speaking into that auditorium indirectly through microphone and amplifier assemblies, one such group being employed to produce full organ effects and another group forming the pedal organ and being employed to produce pedal effects.

Other objects will appear from a consideration of the following description of this invention and of the drawing which forms a part thereof and which illustrates diagrammatically a pipe organ embodying one form of this invention.

The console I0 is provided with stop knobs 20, manuals 2| and 22 and a pedal bank 23 of the usual type, the number and arrangement of the stop knobs, manuals and pedal banks of the console being varied as desired.

The numeral I2 designates the solo organ of the organ which comprises a group of stops or sets of pipes on which the organist plays with one manual 2| and certain stop knobs to produce certain tone color effects. These stops speak naturally and directly into the auditorium in the usual manner. The numeral l4 designates the great organ of the organ and comprises a group which includes stops or sets of pipes, two or three stops being usually sufiicient, acoustically insulated from the auditorium and speaking thereinto through a microphone 25 and amplifier assembly including an amplifier control unit 26 and a loud speaker 21. The stops forming the group M are caused to speak by the manual 22 and certain stop knobs in the usual way from the console including a control knob 28 connected to the amplifier control unit 26 by a suitable lead 29 by which the degree of amplification of the output of the stops is controlled. Thus the organist can obtain from the stops a range of any desired volume which may be that customarily obtained or, if desired, of a fullness and majesty previously obtained only with the largest and most complete full organ installations. lhe numeral 16 designates a group which, like the group I4, includes stops or sets of pipes, two or three stops being usually sufiicient, acoustically insulated from the auditorium and speaking thereinto through a microphone and amplifier assembly. The stops of this group form the pedal organ of the organ and are caused to speak from the console by the pedals in the usual way. In addition the amplification of the output of the pipes is under the control of the organist so that the range may be varied from very soft to very loud and be comparable to that of the pedal department of the largest organs. Such control is shown as similar to the control of the organ l4 and comprises a microphone 30, an amplifier control unit 3|, a loud speaker 32, a control knob 33 and a lead 34.

Thus the console l5 of the simplest form of organ embodying this invention may comprise a manual 21 by which the solo stops in the group 12 are played, a second manual 22 by which the full organ stops in the group M are played, a pedal bank 23 by which the pedal stops in the group i6 are played, suitable stop knobs and controls by which the amplification of the output of the stops in groups M and I5 are regulated. The stops forming the groups 14 and i6 are enclosed in housings 35 and 36 of soundproof material so that they do not speak directly into the auditorium. Should it be desired the stops forming groups 14 and I6 may be enclosed within a single housing and a more compact organ obtained. Controls may be provided at the console so that group I4 or group IE or both may also function as swell or echo organs.

In the above description and in the claims the term auditorium is used to designate the chamher or compartment into which the solo stops speak directly and the full organ and pedal stops speak indirectly. It will be understood that the audition of the music from the organ may be in such chamber or compartment or may be at other locations in which the combined output of the organ is reproduced by the use of microphones and loud speakers or radios.

I claim;

1. A pipe organ comprising a group of stops which speak directly into an auditorium and a second group of stops which speak indirectly into that auditorium, said second group of stops being acoustically insulated from the first group and speaking indirectly into the auditorium through a loud speaker. r

2. A pipe organ comprising a group of solo stops which speak directly into an auditorium and by which the organist can produce a suitable variety of tone colors and a second group of stops acoustically insulated from the first group and speaking indirectly into that auditorium through a loud speaker and by which the organist can produce full organ effects.

3. A pipe organ comprising a group of solo stops which speak directly into an auditorium and by. which the organist can produce a suitable variety of tone colors and a second group of stops acoustically insulated from the first group and. speaking indirectly into that auditorium through a loud speaker and by which the organist can produce pedal efiects.

4. A pipe organ comprising a group of solo stops which speak directly into an auditorium and by which the organist can produce a suitable variety of tone colors and a second group of stops acoustically insulated from the first group and speaking indirectly into that auditorium through a loud speaker and by which the organist can produce full organ eifects and a third group of stops acoustically insulated from the other groups and speaking indirectly into that auditorium through a loud speaker and by which the produce pedal efiects.
