Abstract

The low inflation warning device is a mechanical sound generating apparatus designated for attachment to a wheel assembly such that the apparatus is contained within the pneumatic space formed by the tire and rim. Whenever a condition of low pressure or overload exists on the wheel assembly a warning signal is generated. The signal is initiated by contact of the interior surface of the tire casing with the apparatus. The contact causes a portion of the apparatus to strike an anvil with sufficient force to generate an audible sound. The apparatus is self-setting under the influence of centrifugal force and will generate a warning of insufficient tire pressure or excessive tire load. The apparatus will generate a signal with each revolution of the wheel assembly to which it is mounted. Under extreme low inflation conditions the apparatus will continue to generate periodic warnings without damage to the tire.
