Abstract
An inertia device which controls and produces a sensory effect as a function of a differential in the angular velocities between primary and secondary bodies rotating on a common axis with a friction drive therebetween, commutated by differential speeds of rotation, and with the sound effect functional as a result of said differential speeds of rotation, and all of which is operative through rotation of the primary body in either direction of rotation with the transfer of kinetic energy into the secondary body for control and operation of the sensory effect.

An inertia device for sensory effect and including, primary and secondary free spinning inertia means rotating on a common axis with a friction drive means therebetween, and said inertia means being rotatable at differential angular velocities and said velocity differential being applied to a sight effect means carried by one of said inertia means and comprised of a battery in series circuit with an instantaneously illuminating On-Off diode visible from the device and a commutator switch in said circuit and operated by differential rotation of the primary and secondary inertia means for On-Off control thereof when the primary inertia means is rotatively accelerated.
An inertia device for multisensory effects and including, primary inertia means comprised of a pair of axially spaced wheels of housing configuration and a hub extending between said wheels for driving engagement with an operating string, a free spinning secondary inertia means rotating on a common axis within the housing configuration of the primary inertia means, friction drive means for the secondary inertia means and comprising friction support of a shaft therefrom rotatably through said hub, a first sight effect sensory means housed within one of said wheels and comprising a battery in series circuit with light emitting means visible from the device and a commutator switch in said circuit and operated by differential rotation of the primary and secondary inertia means, and a second sound effect sensory means housed within the other of said wheels and in the form of a siren comprising members of the primary and secondary inertia means wherein streams of air are driven against a relatively rotating circumferentially perforated element to produce sound at a pitch and amplitude dependent upon differential angular velocity between the primary and secondary inertia means.
A yoyo for multi sensory effects and including, a pair of axially spaced wheels comprising a primary inertia means, a hub extending between said wheels for external driving engagement with an operating string, a secondary inertia means rotating on a common axis with the primary inertia means, friction drive means comprising friction support of a shaft rotatably in said hub, a first sight effect sensory means carried by one of said yoyo wheels and comprising a battery in series circuit with light emitting means visible from the device and a commutator switch operated by differential rotation of the primary and secondary inertia means, and a second sound effect sensory means carried by the other one of said yoyo wheels and in the form of a siren comprising members of the primary and secondary inertia means wherein streams of air are driven against a relatively rotating circumferentially perforated element to produce sound at a pitch and amplitude dependent upon differential angular velocity between the primary and secondary inertia means.
