Renewed January 20, 1933 6 Claims. I (01. 84-470),

My invention relates to musical instruments and more particularly to a tone producing mechanism designed to supplement the usual piano.

The primary object of my invention is to pro- 65 vide, a mechanism, for producing vocal tones, which may be mounted in pianos of the usual types and may be'used in connection therewith as an aid in voice culture and in the teaching of singing.

A further object is to provide an auxiliary tone producer, of the character described, which has a tone range corresponding approximately to that of the human voice and which may be adjusted for use separately with each of the several types of voice; namely, soprano, mezzo-soprano, contralto, tenor, baritone or bass.

Still a further object of my invention is to make possible the prolongation of any note that lies within the range thereof and to vary each note in accordance with the five vowel sounds represented by the letters a, e, i, o and u.

Other objects will appear hereinafter, as the details of the invention are described.

' Referring to the accompanying drawing, which 2. illustrates what is at present deemed to be a preferred embodiment of the invention,

Fig. 1 is a fragmentary plan view of a grand or square piano, equipped with my invention, showing the front part of the piano including the keyboard. I

Fig. 2 is an enlarged fragmentary sectional view of the piano shown in Fig. 1, taken approximately on line 2-2 of Figs. 1 and 3.

Fig. 3 is a sectional View taken on line 3-3 of Fig. 2, showing, infragmentary form the disk carrier, which forms a part of my invention, and certain details associated therewith.

Fig. 4is a plan view of one end of the disk carrier and associated parts, as seen when viewed from the front of the piano in the direction indicated by arrow 4 in Fig. 3.

Fig. 5 is an edge view further enlarged of one of the tone disks which are mounted on the disk carrier and whichproduce the vocal tones.

Considered more in detail the drawing will be seen to show my auxiliary tone producer as comprising an adjustable disk carrier 10, equipped with a multiplicity of tone disksll, a series of needles or styluses 12, one of which 'is' associ- 50 ated with each piano key whose tone is to be supplemented, and a series of sound-boxes 13 55 Disk carrier consists of two circular plates 14 and 15 fixed on a central'tubular shaft 16 adjacent its ends which are journaled in bearings 17 formed on standards or brackets 18 and 19 which brackets are adapted to be mounted in the string'chamber of a pianofcasing above the rear extensions of the piano keys, as shown in Fig. 2. Bearings 20 are fixedin plates 14 and 15 and six equally spaced shafts 21 preferably tubular ones, have their ends journaled therein. Each of said shafts 21 has a series of tone disks 11 strung thereon and clamped thereto by nuts 22 so that they turn therewith. One of said series, as at 23, is adaptedto cover the range of a soprano voice, others, as at 24, 25, 26, 27 and 28, are adapted to cover the ranges of a mezzosoprano, a contralto, a tenor, a baritone and a bass voice, respectively, each being somewhat more than two octaves.

Each of the disks 11 has a central opening corresponding in diameter'to that of. the shafts 21 and has ,an approximately V-shaped peripheral groove 29 in its edge as shown inyFig. 5, the bottom of which groove is slightly roundedf'as at 30, so as to receive the "point of a recorder stylus to produce the'record and of a reproducer stylus to reproduce the tone. There are'five disks for each key or note, as is clearly illustrated at 31 in Fig. 4, one for each of the five vowel sounds, a, e, i, oand u, and provision is made for shifting disk carrier 10 longitudinally so as to bring atpleasure, any of said five disks into alignmentwith the stylus of that key or note, this being necessary because thepositions of the styluses arefix'ed so that they can notbemoved laterally.

Brackets 18 and 19 are spaced apart at a distance somewhat greater than the length of disk. carrier 10 and the extensions of shaft 16 beyond plates 14 and 15 are made sufficiently long to permit the necessary longitudinal shifting of the disk carrier. A knurled nut or knob 32 is provided on'one end'of shaft 16 whereby this shifting readily may be done and whereby the shaft also may be turned'in bearings 1'7. 7

Sixl regularly spaced square notches 33 are cut in the edge of circular plate 14 and a like number of similarly spaced V-shaped notches 34 are cut in the edgeof plate 15. A spacing plate 35 hav ing a'series of five square notches 36, of suflicient widthto permit the edge of plate 14to run there- I in, cut in its lower edge, is fixed above plate 14 to an upper extension 18' of bracket 13, and a locking" plate 37' adapted to be actuated down- Wardly by a spring 38,into notches 33 of plate 14, is loosely attached to spacing plate 35, as shown in Fig. 3. A spring actuated latch-bar 39, adapted to snap into notches 34 and thus indicate the proper angular positions of the several series of disks for action, is pivotally attached to bracket 19, as at 40.

It will be seen that the disk carrier will be locked inflany one of its six active positions by the action of locking plate 37 as it enters one of the notches 33 in plate 14. It will be seen also that the disk carrier can be shifted longitudinally only when looking plate 37 is pulled upwardly so as to be withdrawn from any of the notches 33 andwhen the disk carrier has been turned 'sufii ciently to bring spacing plate into alignment with one of the notches 33. It mustbe understood, of course, that the spacing of notches 36, in plate 35, corresponds to the spacing of the grooves in the groups of five" disks which belong to each note or key, as explained above.

Shafts 21, upon which tone disks 11 are strung, are revolved in bearings 20 when in; their active position by connecting each in turn to a'stub shaft 41 which is journaled in a bearing 42 formed on a lateral arm 19 of bracket 19. A pulley 43, adapted to be driven by a belt 44, coming from an electric motor or the like, (not shown) is fixed onstub shaft 41 which has an axial hole, square in cross section, extending therethrough. One end of each shaft '21 is provided with a square socket 45, of equal cross section to that of said axial hole through stub shaft 41, and connection of the former shaft with the latter is made by a square pin 46 extending through the latter into socket 45 of the former. A knob 47 is formed on one end of pin 46 whereby it readily may be withdrawn 1 whenany change in adjustment is to be made.

Styluses 12 are sapphire-pointed and are pivoted between cone points 48 in the usual manner. They are provided with apertures 49, adjacent their pivoted ends, through which apertures the upper ends of the usual damper rods '50, associated withi'each piano key, extend.

The projecting ends of damperrods 50 are bent to form a laterally extending pin 51' adapted to contact with the upper edge of the stylus so as to hold its point out of engagement with the tone disk, except when'the piano key is'depressed, as is clearly illustrated in Fig. 2. Springs 52, adapted to actuate styluses 12 toward tone disks- 11, when the piano keys are depressed and the damper rods are lifted in the usual way, so as to bring the stylus points into engagement with the grooves of the tone disks with a suitable amount of pressure, are attached to the front I ends of sound boxes13.

The sound boxes are attached to a cross-bar '53 which is adapted to support them in properly spaced .relation to disk carrier 10, within the string chamber of the piano. Pairs of wires 54,

leading from each sound box unit, are connected adjusted for usethe piano is played in the usual manner. I {voice singing note for note onone of the five The musical effect is that of a human vowels with the piano, within the range of operation of that particular voice. By holding down the piano key the voice notes may be prolonged indefinitely beyond those of the piano, thus affording an opportunity for close study of the several voices and the different vowel sounds.

It will thus beseen thatmy invention isuseful not only for producing a unique kind of piano music,v but also and more especially for vocal :practice in musical studios by students as well styluses adapted to engage said tone disks so as to reproduce the tones recorded thereon, when the piano keys'are depressed; a series of sound boxes connected to said styluses so as to receive their vibrations, means to turn said disk carrier on itsshaft to bring'the tone disks mounted on an individual shaft thereof into position to be engaged by said styluses, and means for revolving said shafts when the tone disks thereon are in position to be engaged by said styluses.
