Device for adjusting the vertical position of wick in oil burner

摘要

A device for adjusting the vertical position of a wick in an oil burner is disclosed which is capable of keeping the lowermost position of the wick constant irrespective of the variably set uppermost position thereof. The device comprises a stopper forced by a spring against a gear fitted on a wick operating shaft, the gear being adapted to be rotated with the shaft to wind a return spring for the gear when the shaft is rotated to move the wick upwardly. A control member is fitted on the shaft and provided with a stopper actuating portion which moves the stopper against the spring means to release the engagement between the stopper and the gear. The control member is adapted to be engaged with the shaft and the gear at a desired position, and the shaft is reversed by the return spring when the stopper is moved to be disengaged from the gear.
