Abstract
A meat thermometer for barbecue grills, broilers, or ovens having a stem containing a bimetallic element in one end thereof, a cylindrical housing secured to the other end of the stem, an indicator within the housing and rotatable in the housing in response to changes of temperature as detected by the bimetallic element, said housing including a cap secured thereto by means passing through the housing and located out of the path of said indicator. The cylindrical housing has a semi-circular slot through which said indicator is visible, said semi-circular slot having temperature calibrations on its surface.

- a cylindrical indicator face fixedly sandwiched between said disk and cap, said cylindrical indicator being a strip which has its ends brought together to form a cylinder of approximately one inch outside diameter,
- said cylindrical indicator face being uncovered,
- indicia indelibly formed on said indicator face and adapted to withstand direct exposure to flame, smoke and grease accompanying broiling meat,
- a bolt eccentrically located with respect to the axis of said stem clamping said disk and cap against said cylindrical face,
