Claim 1
Independent Claim
241 words
A stove, comprising, in combination: (a) an external casing provided with an opening; (b) a fire chamber disposed within the casing and provided with a hole arranged adjacent to and in communication with the opening provided in the casing, the fire chamber including a planar grate arranged extending between side walls of the casing; (c) door means disposed removably covering the opening; and (d) a flue pipe connected to the fire chamber and extending out of the casing for carrying combustion gases from the fire chamber, the door means including, in combination: (1) a cowl mounted on the casing and surrounding the opening provided in the casing, the cowl arranged extending away from both the casing and the fire chamber; (2) a cover pivotally mounted on the cowl; (3) lock means mounted on the cover and selectively engageable with the cowl for releasably securing the cover to the cowl; and (4) vent means provided on the cover for controlling draft to the fire chamber, the vent means including a slide guide, a slide disposed in the slide guide for reciprocating movement relative thereto, perforations being provided in the cover and slide for matching and mismatching with one another, and a divider placed on the casing and disposed extending into the cowl substantially coplanar with the grate, the divider being arranged bisecting the perforations and causing both over and under draft in order to provide better burning control with the fire chamber.
