Claim 1
Independent Claim 264 words
A collapsible camp stove that folds into a self-contained substantially rectangular package, comprising: a rectangular main body; a front plate and a rear plate, each hinged along one of its sides to said main body and each having a hole of predetermined shape adjacent each of two opposite sides normal to said hinged side; four fasteners, one of said fasteners being slidably retained within each of said holes in said front and rear plates respectively; two side plates, each hinged along one of its sides to opposite sides of said main body and each formed with end flanges each provided with a locking hole of predetermined shape to receive a portion of one of said fasteners when placed adjacent thereto, said fasteners and said locking holes being so positioned that when said side plates are moved to form corners with said front and rear plates, respectively, adjacent plates become connected when said fasteners are moved downwards and are subsequently disconnected when said fasteners are moved upward; fuel support means for supporting burning fuel within and above the inside bottom surface of said main body; base plate means, underneath said burning fuel and above the inside base surface of said main body, for receiving ash and cinders from combustion of said burning fuel; combustion rate control means, attached to said main body, for controlling the rate at which combustion of said fuel is carried out on said fuel support means; and food support means, for supporting food items at a predetermined height above said burning fuel, supported by said rear plate and said front plate.
Claim 2
Dependent Claim 264 words
A collapsible camp stove that folds into a self-contained substantially rectangular package, comprising: a rectangular main body; a front plate and a rear plate, each hinged along one of its sides to said main body and each having a hole of predetermined shape adjacent each of two opposite sides normal to said hinged side; four fasteners, one of said fasteners being slidably retained within each of said holes in said front and rear plates respectively; two side plates, each hinged along one of its sides to opposite sides of said main body and each formed with end flanges each provided with a locking hole of predetermined shape to receive a portion of one of said fasteners when placed adjacent thereto, said fasteners and said locking holes being so positioned that when said side plates are moved to form corners with said front and rear plates, respectively, adjacent plates become connected when said fasteners are moved downwards and are subsequently disconnected when said fasteners are moved upward; fuel support means for supporting burning fuel within and above the inside bottom surface of said main body; base plate means, underneath said burning fuel and above the inside base surface of said main body, for receiving ash and cinders from combustion of said burning fuel; combustion rate control means, attached to said main body, for controlling the rate at which combustion of said fuel is carried out on said fuel support means; and food support means, for supporting food items at a predetermined height above said burning fuel, supported by said rear plate and said front plate.
