Claim 19:
20. An automatically locking, releasable, safety knob assembly, comprising:
a base configured to mount to a stove surface of a stove, the base comprising:
a disk portion;
an outer peripheral sidewall; and
an inner peripheral sidewall, the inner peripheral sidewall comprising a locking notch;

an adapter configured to mate with a valve stem of the stove extending through the base, the adapter comprising:
a head;
a tubular middle section;
an adapter base; and
an adapter central aperture extending through the adapter base, the tubular middle section, and the head, the adapter central aperture configured to receive the valve stem of the stove;

a knob comprising:
a knob housing; and
a housing disk covering the base, the housing disk comprising:
an arm movement channel aligned with the locking notch when the safety knob assembly is in a locked configuration;
a housing disk central aperture, the housing disk central aperture configured for receiving the head of the adapter; and
a sliding attachment dowel, the sliding attachment dowel configured to mate with a central arm movement aperture; and

an automatically locking, releasable, sub-assembly, comprising:
a slidable button configured to allow free rotation of the knob when the safety knob assembly is in an unlocked configuration; and
an automatic locking arm resiliently biased with the slidable button, the automatic locking arm comprising the central arm movement aperture, the central arm movement aperture being angled in a direction opposite of the slidable button;

wherein the safety knob assembly is in the locked configuration and the sliding attachment dowel is in a lower portion of the central arm movement aperture causing the automatic locking arm to engage with the locking notch and further causing the knob to be in the locked configuration and the valve stem to be in an off position preventing rotation of the valve stem; and
wherein the slidable button is not engaged and the automatic locking arm is engaged with the locking notch preventing the automatic locking arm from moving in the arm movement channel causing the safety knob assembly to be in the locked configuration and preventing the knob from freely rotating preventing rotating of the valve stem.
