Stove deactivation timer assembly

摘要

A timer assembly includes a knob operationally coupled to a stove. A shaft is operationally coupled to the knob. The shaft selectively engages a valve on the stove. The knob is retained on the stove. The shaft opens the valve when the knob is rotated to an on position. The shaft closes the valve when the knob is rotated to an off position. A timer is operationally coupled to the shaft. The timer urges the knob to the on position for a selected duration of time. A spring biasing member is operationally coupled to the housing. A strip is coupled between the shaft and the spring biasing member. The spring biasing member urges the knob to the off position. The spring biasing member moves the knob to the off position after the timer ceases urging the knob to the on position.
