## Abstract

A musical toy comprising a tone generator, a plurality of spaced apart generator contacts respectively associated with differing musical tones of a musical scale; at least one set of contactor members; at least one set of receiver members uniquely adapted to receive the set of contactor members in a fixed predetermined relative position; displacing members for displacing said receiver members while maintaining said fixed relative disposition in juxtaposition to the contacts so that they are successively actuated by the receiver members in accordance with a predetermined sequence thereby generating a predetermined sequence of tones.

## Claims

### Claim 1

A musical toy comprising a tone generator, a plurality of spaced apart generator contacts respectively associated with differing musical tones of a musical scale; at least one set of contactor members; at least one set of receiver members uniquely adapted to receive said set of contactor members in a fixed predetermined relative position; displacing means for displacing said receiver members whilst maintaining said fixed relative disposition in juxtaposition to said contacts so that they are successively actuated by said members in accordance with a predetermined sequence thereby generating a predetermined sequence of tones.

### Claim 2 (depends on 1)

A musical toy according to claim 1 wherein at least a like plurality of sets of receiver members are provided, the constituent receiver members of each set having a fixed predetermined spatial disposition with respect to each other, said sets of receiver members being respectively juxtaposed with respect to said contacts, said contacts being actuated as a consequence of successive juxtaposition with respect thereto of those receiver members of the juxtaposed set of receiver members having located therein contactor members.

### Claim 3 (depends on 2)

A musical toy according to claim 2 wherein each set of receiver members have a like spatial distribution with respect to each other and are mounted on a common support, said displacing means being arranged to displace said supports in synchronism.

### Claim 4 (depends on 3)

A musical toy according to claim 3 wherein there is provided a central tooth wheel and a plurality of toothed planetary wheels in geared interengagement with said central wheel respectively constituting said supports; said displacing means being constituted by means for rotationally displacing said central wheel.

### Claim 5 (depends on 4)

A musical toy according to claim 4 wherein the constituent receiver members of each planetary wheel comprise respective apertures peripherally distributed about said wheel, aperture identifying wheels for separately identifying each aperture, and corresponding contactor member identifying means for separately identifying each contactor member so as to correlate each contactor member with a separate aperture.

### Claim 6 (depends on 5)

A musical toy according to claim 5 wherein each planetary wheel is provided with distinctive identifying means associated with a separate musical tone and wherein separate sets of contactor members are provided with corresponding identifying means whereby said sets of contactor members are respectively associated with said wheels.

### Claim 7 (depends on 6)

A musical toy according to claim 6 wherein the constituent apertures of each planetary wheel are of respectively differing shapes and wherein the constituent contactor members are respectively formed so as to be uniquely receivable by said apertures.

### Claim 8 (depends on 7)

A musical toy according to claim 7 wherein said planetary wheels are respectively associated with differing identifying colours and wherein said sets of contactor members are similarly associated with said colours.
