ABSTRACT:
A locking mechanism for ranges utilizes a bar extending transverse to the longitudinal axis of the knob operated shafts controlling the operation of the individual valves of a gas range or the individual switches of an electric range. A plurality of arms are pivotably secured to the bar, each having fingers directed and biased towards the longitudinal axis of each shaft. Each shaft is rotatable and carries an opening at a discrete location in the surface thereof. Rotating the shaft to a position corresponding to deenergizing the associated heating element of the range into an off position permits the free end of the finger to enter the opening, preventing further rotation of the shaft when the bar is slidably positioned into a locked position by the operation of a key operated lock. When the lock is placed in an unlocked position, the bar is slidably displaced permitting those fingers engaged within associated openings to become disengaged, thereby allowing all of the shafts to be manually independently operated.
