Food temperature measuring device with audible signal

摘要

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.
