摘要

A device for adjusting the vertical position of a wick for an oil burner is disclosed which is capable of effectively and positively keeps the combustion position of the wick within a range of constantly attaining the normal combustion of the oil burner. The wick adjusting device includes a circular member fitted on a wick operating shaft and received in a slidable knob to be moved with the knob. The circular member is formed with a slot in which a pin-like projection of a gear is movably fitted and with which the projection is engaged at the minimum combustion position to prevent the knob from being further rotated in the fire-extinguishing direction during the combustion operation.
