1. A safety device for an oil burner comprising:
- an abnormal combustion sensing and actuation mechanism arranged to receive heat rays emitted from a combustion cylinder construction of said oil burner to detect abnormal combustion which occurs in said oil burner after a normal combustion forming a combustion flame emitting heat rays of at least a predetermined intensity and which forms an excessively decreased flame sufficient to produce incomplete combustion gas; and
,a starting means for starting a fire-extinguishing device of said oil burner, said starting means being operatedly connected to said abnormal combustion sensing and actuation mechanism so as to be actuated to operate said fire-extinguishing device when said abnormal combustion sensing and actuation mechanism detects said abnormal combustion occuring after said normal combustion, said abnormal combustion sensing and actuation mechanism including means for preventing said actuation of the starting means for a period of time after ignition of the oil burner sufficient to provide said normal combustion.

Abstract
A safety device for an oil burner is disclosed which is capable of detecting abnormal combustion which forms an excessively decreased flame, for example, sufficient to produce incomplete combustion gas to operate a fire-extinguishing device of the oil burner. The safety device includes an abnormal combustion sensing and actuation mechanism which is adapted to receive heat rays from the oil burner to detect the abnormal combustion and a starting member selectively actuated by the mechanism to operate the fire-extinguishing device when the mechanism detects the abnormal combustion.
