Abstract
Abstract A timer for various meats including poultry to audibly indicate when the meat has been cooked to a desired extent. The timer includes an elongated container filled or partially filled with a solution, and having a pointed end to be forced into the meat. The other end of the container is closed and sealed by a cap which is responsive to pressure generated in the container, by the liquid being converted to steam, to effect movement of the cap to a position to allow the steam to escape from an opening of the cap, which was initially sealed, to produce an audible signal indicating that the cooking of the meat has been completed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
89 words
A meat timer comprising a hollow sealed body adapted to be inserted into a piece of meat to be cooked, said body containing a liquid which is converted to steam when the meat reaches a predetermined temperature, said body comprising two movably connected parts, one of said parts having a steam escape port movable with said part in response to the steam pressure to an exposed position to permit escape of the steam from the body, said port being shaped such that the escaping steam produces an audible signal.
Claim 2
Dependent Claim
89 words
A meat timer comprising a hollow sealed body adapted to be inserted into a piece of meat to be cooked, said body containing a liquid which is converted to steam when the meat reaches a predetermined temperature, said body comprising two movably connected parts, one of said parts having a steam escape port movable with said part in response to the steam pressure to an exposed position to permit escape of the steam from the body, said port being shaped such that the escaping steam produces an audible signal.
Claim 3
Dependent Claim
