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 temperature sensitive spring in bi-metallic communication. As the internal temperature of the substance increases, the temperature sensing material and spring slowly rise causing the disk to rotate back to its original position. When the original position is reached, the actuation pin on the temperature pointer activates a series of levers which release a manually pre-wound coil spring. The unwinding of the coil spring activates a large gear which then activates a small gear causing a clapper with a plurality of wings to spin in circles and repeatedly ring a bell. Thus, the user is audibly alerted when the internal temperature of the substance reaches the desired threshold level.
