PERFECCIONAMIENTOS INTRODUCIDOS EN UN INSTRUMENTO MUSICAL.

摘要

A toy musical vehicle can be constructed within a simulated vehicle body so as to utilize a single motor to simultaneously drive and operate a music producing mechanism and the vehicle. The vehicle is driven by coupling the motor to wheels of the vehicle through the use of a conventional gearing arrangement. The music producing mechanism preferably includes a fan which supplies air under pressure to a wind chest coupled to the motor. This wind chest is utilized in conjunction with valve actuators and valves which control the release of air so as to create sound in a conventional manner. The valve actuators are normally biased outwardly from the wind chest by the pressure of the air within the wind chest so that followers on these actuators are in a position to be engaged by any of a plurality of cams formed so as to extend from the surface of a rotary record member. The periphery of such a record member is formed as a ring gear and mates with a spur gear driven by the motor through a drive train. This record member is supported in a vertical slot in such a manner that it can be dropped in place so as to be rotated by the spur gear in order to bring the cams into contact with the followers so as to move the actuators and associated valve members to selectively control the flow of air from the wind chest. The music producing mechanism is capable of and is considered desirable for independent utilization apart from such a vehicle.
