Grill height adjustment and indicator mechanism and methods of use thereof

A grill height adjustment and indication apparatus comprising:

• a rotatable grill height adjustment crank connected to a driving shaft;
• a gearbox connected to the driving shaft, wherein the gearbox translates the rotation of the adjustment crank to a substantially vertical movement of an adjustable grill rack via a worm gear operatively connected to the grill rack;
• a rotatable indexing driving member operatively connected to the driving shaft, wherein the indexing driving member has a convex portion and a pin;
• a rotatable indexing driven portion, wherein the indexing driven portion has a concave portion and a slot, wherein the rotation of the indexing driving member causes the pin to interact with the slot during a rotation period of the indexing driven portion and the concave portion to interact with the convex portion during a dwell period of the indexing driven portion;
• a rotatable indication portion having a plurality of height indicators, wherein one of the plurality of indicators is substantially stationarily displayed during a dwell period of the rotatable indexing driven portion and the rotatable indication portion rotates to another of the plurality of height indications during a rotation period of the rotatable indexing driven portion;
• and
• an audible indication portion operatively connected to the grill height adjustment crank, wherein the audible indication portion produces an audible tone at increments that correspond with a rotation of the rotatable indexing driven portion.
