Abstract
An improved oil stove of the type including a cylindrical burning wick adapted to be raised up or lowered as required by actuating a wick control handle is disclosed which includes a stopper slidably secured to the wick control handle and a stopper engagement member to which the stopper comes in engagement as the wick control handle is rotated. The stopper comprises a base plate, an engagement projection and a depress button adapted to be depressed by an operator's finger. The engagement projection is extended from the base plate to the position where it is engaged to the stopper engagement member at its upright bent portion of which upper end face is tapered. As the wick control handle is rotated in such a direction as to lower the wick, the bent portion of the engagement projection abuts against the stopper engagement member and thereby the wick control handle fails to be rotated further. On the contrary, as the wick control handle is rotated in the opposite direction so as to raise up the wick, the stopper engagement member comes in sliding contact with the tapered end face of the engagement projection and therefore the wick control handle continues to be rotated without any hindrance. When the wick control handle is to be rotated further in the direction of lowering of the wick, the depress button is manually depressed so that the whole stopper is disengaged from the stopper engagement member. Thus, the wick control handle can be operated further.
