This invention'has reference to improvements in, and relatingto the production of color music or the harmony of color and musical sounds, andother spectacular effects, and apparatus thereforin which the movements of the keys of a piano, piano player, organ, or other keyboard are made to ope-rate a series of switches and/or relays so as to display or project colored lights in such manner as to harmonize withmusical sounds.

The main object of the invention is to express more efiectively'by meansof lights the emotions of a musician, through the keyboard of a musical instrument or the like. There may be used in some in stances,.a silent keyboard, that is, Without the agency of sound, toproduce luminousdisplays.

The invention consists briefly of the arrangements and/or projection of colored lights according to a color scale of treble and bass notes and in apparatus whereby the mechanism of piano players, organs, or other keyboard instruments may be conveniently utilizedto obtain the desired efiects, and in means for the reflection and diffusion of light and the production of shadows.

,It is wellknown that ifvthe space occupied by the normal spectrum be divided, the various colors occupy different proportions of this space. The ratios of each color may be determined and .form the,basis for a color scale.

Advantage is taken of this to construct what is termed a color .scale of treble and bass notes.

In applying the color scale to .the keys of a keyboard musical instrument'I start at the lowest bass note and proceed upwardly.

The scale or ratio of the spectrum colors may be arranged over the variouskeys and octaves in several ways.

In applying the lighting efl'ects the use of a. spiral, known as. the logarithmic spirahthe nebular hypothesis, the aurora borealis, or vortices is resorted to, that is to say, I have ascertained that all sound harmonics are curvesor spirals and that the nearer the approximate curve or spiral is to the presentation oflight the closer the simultaneous *harmonic effect of sound and light, and in 204,086, and in Australia July 15, 1926.

this manner the 'formand color of music are rendered visible. In short the analogy of the spinning electron is followed. 7 I

The invention, in its simplest practical form, comprises aplurality of electric lamps arranged according to the chromatic scale of colors, in segments of a circleor s iral which segments or sectors may eaten f rom the periphery to a center, and the color in each sector is graduated or shaded from theperiphery to the center. Preferably, however, one, or a plurality of electric lights of graduatedsize is provided to correspond with one or a series of pendulums ofdifi'erentlengths on whichsaid lights are mounted orlcarried. By these means the lights take the swinging t o their speet Y P ndulum parted from the keyboard .until they slow down to afstateof re st or are stopped by a pedal or other means controlled from the keyboard. The pendulums maybe provided with universal joints whereby a vortex, to and fro, or other rhythmic movement, may

.be obtained.

h ap a a u m y .b .perta l a .keys or'hammers ofa keyboard instrument part of the circnitarrangement for controlling the lights from a keyboard, the dis position of the lights being in the form of a logarithmic spiral shown in elevation.

Figure 3 is a diagrammatic plan view of the logarithmic spiral shown in Figure 2.

Figure 4 is a part diagrammatic inverted plan View of the arrangement of lights in groups or clusters in a dome also in the form of logarithmic spirals.

Figure 5 is a sectional view of one of the keys of a keyboard instrument, illustrating an alternative circuit arrangement for producing a sustaining effect on the lights.

Figure6 is a-perspective view of a suitable form of quick acting relay for closing the lamp circuits.

Referringto Figures 1 to 6, the piano and organ 16 are electrically connected in multiple to relays in the relay box 17. The relays may be of any suitable type but are preferably of the quick acting type shown in Figure 6. Each relay is controlled by a switch operated by one of the keys of the musical instrument and is adapted to complete the circuit for the respective lamps or groups of lamps under its control.

The lamps 18, which may have reflectors 19, are arranged in the form of a logarithmic spiral, shown in dotted lines in Figures 2 and 3, and diagrammatically as clusters of lamps in Figure 4. Each turn of the spiral represents one octave and is composed of twelve lamps or groups of lamps. For a seven octave keyboard instrument a seven turn logarithmic'spiral in which each turn has twelve lamps or groups of lamps would be provided.

In Figure 4 seven clusters of lights 20 are shown, each of which is controlled by the same note in the seven respective octaves of the keyboard instrument. In a similar manner the other eleven notes of each octave would each control a cluster of lights arranged in a vsimilar way to those shown in the drawing.

Beneath each note contacts are arranged, (see Figures 2 and 5). These are adapted on the depression of a note to complete a circuit for energizing a relay whereby a lamp, or group or cluster of lamps is lighted.

Referring to Figures 1 to 4, when one of the keys 21 of the piano 15 or organ 16 is struck by a musician or mechanical player, the following circuit is completed: from battery 22, contact bar 23, contact 24, wire 25, relay 26, wires 27, 28 and 29, back to battery 22. When the above circuit is completed, the relay 26 closes contacts 30 and completes the following lamp circuit: from positive main 31, wire 32, lamp or lamps 18, wire. 33, to the negative main 34.

In order to sustain a particular lamp or lamps after a particular key has been played, additional contacts 39 are provided onthe relay 26 in order to effect a locking circuit for the relay, which operates as follows. Upon the closing of a pedal or like operated switch 35, a circuit is completed as follows: from battery 22, switch 35, wires 36, 37 and 38, contacts 39, relay 26, wires 27, 28, 29, to battery 2 From the above circuit it will be seen that if a particular key is played and the respective relay contacts closed, the lamp will remain lighted provided the sustaining switch is closed, causing the relay to be energized by the sustaining circuit. If the particular key returns to its normal position and opens switch 24, the particular lamp will remain lighted so long as the sustaining switch 35 is closed.

In the modified sustaining mechanism shown in Figure 5, each of the keys 21 of the keybard instrument has a back contact member 40 which is springy and has a soft iron tip or keeper 41. A soft iron bar 42 is supported by and capable of being magnetized by an electromagnet 43 mounted above the keyboard of the instrument and extending longitudinally thereof and which when mag net-ized is capable of retaining the tip or keeper 41 in contact therewith once a key has been depressed, and during such time as the sustaining switch is closed by a pedal or like opera-ting means to complete an independent circuit for energizing the electromagnet 43. WVhen a keyboard instrument is installed with the modified arrangen'ient shown inFigure 5, the lamp circuit closing relay 's energized as follows. When a particular key 21 is depressed current flows from battery 22 by way oi? wire 49, contact 24, screw 44-, wire 45, lamp circuit closing relay 26, wires 46, 47, 48, back to battery 22. The energization of the relay 26 causes the contacts 30 to close the lamp circuit 01? the particular lamp or group of: lamps corresponding to the note struck.

If it is desired to sustain the lamp in lighted condition, the sustaining switch 35 closed to energize the electromagnet 43 by means of current supplied from battery 50.

This has the effect of magnetizing the bar 42 so that when a particular key is struck the back contact member 40 is raised until the tip or keeper 41 engages the magnetized bar 42 against which it is held as long as the.

switch 35 is closed. Current will now pass from battery 22, wires 49, 51, bar 42, contact member 40, wire 45, relay 26. wires 46, 47, 48, had; to l attery 22, with the res-iult that relay 26 maintains the lighting current oi the particular lamp closed as long as the sustaining switch is closed, even when the note 21 returns to its normal position.

Figure 6 illustrates one oi the lamp circuit closing relays 26 which are of the quick acting type. Each relay has electromagnetic coils 51 and contacts 30 which are bridged by the keeper 52. The operating arm 53 is seoured to the arnuitiiire oi? the relay and is loosely pivoted on pins 54, adjustment being effected by the screw 55. In operation, this relay works as "follows. hen the coils are energized the armature is attracted, causing the arm 53 to depress the keeper 52, and at the same time the coupling 56 raises the contacts 30 which, on engagement with the keeper, completes the circuit from terminal 57 to terminal 58. The contacts 30 are normally insulated from each other by a distance piece 59.

The lamps 18 with their reflectors 19 may be mounted on a universal joint 88 and be arranged to swing with a pendulum action when released by an electromagnet 84.
