Musical chime device

Claim 2

A replaceable electric melody circuit board record for engagement with an electronic oscillator tone generating means for automatic play of a melody when continuously sweeped by electrical connecting means comprising: a removable printed circuit board with a playing surface, sequential and variable sized electrically conductive areas of melody control area means on said playing surface to provide a melody in conjunction with an electronic oscillator tone generating means, said melody control area means sized to provide the time length of each tone when sweeped by connecting means, said melody control area means spaced apart to provide the time length of the pause between each note, and said melody control area means oriented in a single path pattern from start to finish for providing a complete melody, the edge of said melody circuit board including connector means interconnected with said melody control area means for sequentially picking up the proper tone when connected to an electronic oscillator tone generating means to provide various melodies from different printed circuit boards.

Claim 3

A replaceable electrical melody circuit board record for engagement with an electronic oscillator tone generating means for automatic play of a melody when continuously sweeped by electrical connecting means as set forth in claim 1 wherein, said pattern is a circular pattern, and said melody circuit board record is a single board that is replacable for providing different melodies when a door bell is actuated.

Claim 4

A replaceable electrical melody circuit board record for engagement with an electronic oscillator tone generating means for automatic play of a melody when continuously sweeped by electrical connecting means as set forth in claim 1 in combination with; a musical melody device for producing a plurality of melodies from a plurality of melody circuit board records by actuating a switch means in an electrical circuit including, said switch means in said electrical circuit connectable to a source of power, an electrical tone generating means connected to said switch means, at least one interchangeable said melody circuit board record connectable to said tone generating means, said melody circuit board record connected through said connector means to said tone generating means to produce various tones of a particular musical score of a melody, a connecting means connected for completing said electrical circuit and connected for automatically sequentially sweeping and making contact with said melody control area means, an amplifier means connected to said tone generating means, and a speaker means connected to said amplifier means for automatically producing an audible melody when said switch means is actuated and as said connecting means makes contact.

Claim 5

A melody circuit board record combined with a musical melody device as set forth in claim 3 wherein: said switch means is a door bell actuating means for providing a replaceable melody announcement means for door entry, said melody control area means is a tone selecting means when said melody circuit board is connected by said connector means to said tone generating means, said tone generating means is an electronic oscillator circuit means for producing melody tones, and an automatic drive means connected to said connecting means to drive said connecting means through a cycle of operation to complete the electrical circuit and provide the proper timing.
