ABSTRACT:
A contents measuring tea kettle having a pivotally mounted handle which swings relative to a fluid-holding container portion of the kettle for actuating a load indicator assembly in order to permit measurement of the amount of fluid in the container as the container is being filled with the fluid. The load indicator assembly includes a spiral torsion spring connected to a dial member of the assembly and to a stationary portion of the kettle for placing a resistance between the pivotally mounted handle and the container of the kettle and causing a reading on the dial assembly which is a function of the amount of water within the kettle at a particular point in time. Further, the contents may be poured from the container, when the latter is only partially filled, in a controlled manner as though the handle were not pivotally mounted.
