Abstract
A device for vertically moving a wick in an oil burner is disclosed which is capable of constantly ensuring the normal combustion operation of the oil burner. The device includes a drive shaft having a pinion, a rack disposed adjacent to a wick receiving chamber of the burner which is engaged with the pinion and connected to a wick to vertically move it when the drive shaft is rotated, and a stop member for stopping the movement of the rack with respect to the pinion only when the wick is lowered to the minimum normal combustion position to thereby ensure the normal combustion.
