Abstract

A safety lock for burners controlled by thermostat, characterized by an automatic device comprising a control device, a first mechanism that can act to put into service said device, a second mechanism that can act to disconnect said first mechanism once a first time interval after having put into service said device, said first mechanism being adapted to take out said device when said first mechanism is disconnected, and a third mechanism that can act in response to the proper operation of said device to disconnect said device. Second mechanism, allowing the disconnection of said second mechanism the continuous action of said first mechanism and said device, said third mechanism being adapted to disconnect said second mechanism before said time interval elapses when said device acts properly.
