Abstract
The present invention is a temperature measuring device for insertion into food which audibly signals the user when the temperature of the food reaches a predetermined level. The stem of the device contains a coiled temperature sensitive bi-metallic spring. As the internal temperature of the substance increases, the temperature sensing material slowly rotates, causing a pointer and triggering disk to rotate. When the rotation achieves a predetermined position, a pre-wound coil spring is permitted to engage a drive gear which operates a hammer device so as to provide an audible signal. Thus, the user is audibly alerted when the internal temperature of the substance reaches the desired threshold level.
Claims4
An audible temperature measuring device for food, comprising;
- a base having a top surface and a bottom surface, said top surface defining a cup shaped housing, said bottom surface having a temperature sensitive probe formed integral thereto and extending outwardly therefrom;
- an integral spring-type alarm mechanism positioned within said housing;
- a heating element operatively associated with said temperature sensitive probe, said heating element mechanically coupled to a temperature indicating means and to an audible alarm mechanism triggering means;
- and
- an adjustable temperature actuator coupled to said alarm mechanism, said actuator including a pointer manually positionable over a temperature indicia plate, said actuator adjusted by a lever extending outward from said base;
- wherein a desired temperature is selected by moving said pointer over a temperature range and said probe inserted into a food substance whereby said audible alarm is activated upon the elevation of said food substance to a temperature approximate the desired temperature.
