Abstract
Abstract In a pit-type slow cooking apparatus, smoldering fuel elements are held on a substantially balanced seesaw support near and above a heating element in the bottom of the pit or enclosure. Food is supported at elevations above the smoldering solid fuel. As the fuel is slowly consumed without open burning or flaming, seesaw movement of the fuel support affords alternate cooling and heat exposure periods for the solid fuel to promote slower and more controllable burning.

A cooking apparatus comprising a housing having a smoke outlet, an upper chamber in said housing having food supporting means therein, a lower chamber of said housing having solid fuel slow burning means therein, said solid fuel slow burning means comprising a substantially balanced workable fuel support tray in said lower chamber, a horizontal axis fulcrum on which said support tray rests, and a heating element positioned below said tray at a fixed elevation in said lower chamber.
Claim 3
Dependent Claim
40 words
A cooking apparatus as defined by claim 1, and a leg support structure for said rockable tray at the bottom of said housing, said rockable tray including a rocker shaft rockably mounted on said leg support structure at said fulcrum.
Claim 4
Dependent Claim
