ABSTRACT:
An improved oven of a type having an on/off pilot and gas valve for receiving gas, with the on/off pilot and gas valve being purely mechanical and having inner workings and a manually operated push button knob, a pilot in communication with the on/off pilot and gas valve and the oven for igniting the oven, a manually operated shut-off valve in fluid communication with the on/off pilot and gas valve for shutting off the gas, and a thermostat in fluid communication with the pilot and in fluid and mechanical communication with the oven for controlling the temperature of the oven. The improvements include an electrical clock timer in electrical communication with the on/off pilot and gas valve for automatically turning on and off the gas output to the oven burner of the on/off pilot and gas valve at a preselected time so as not to allow gas to flow to the oven burner when the oven is not in use and waste the gas, with the preselected time being sufficient to have the oven pre-heated to operating temperature by the time the oven is first used, the on/off pilot and gas valve being electromechanical for electrical and mechanical activation, and the electrical clock timer not being mechanically connected to the manually operated push button knob of the on/off pilot and gas valve, but rather being in electrical communication with the inner workings of the on/off pilot and gas valve, which reduces exposed components and thereby eliminates mechanical failure thereof.
