709,998. Solid-fuel stoves. RADIATION, Ltd. June 5, 1952 [June 19, 1951], No. 14486/51. Class 126 A closed solidfuel stove with air supplied above and below the grate has a conduit arranged so that a full supply of primary air can be fed above the grate and a restricted supply of primary air fed below the grate, or a full supply of primary air can be supplied only below the grate and dampers to control the air flow. Primary air is admitted to a stove above the grate b through a passage c and below the grate through an opening o. Secondary air is admitted through an inlet e near the combustion products outlet d. Incorporated with the stove is an air conduit, Fig. 2 (not shown), having two passages h, i formed at its upper end, the inlets to which are controlled by a common damper which may be thermostatically operated. The passage h leads to the inlet c above the grate, while the passage i leads through a lower part n of the conduit to the ash space air inlet o. The passage i has a restricted inlet, and a hole is formed in the partition between the passages hand i. When this hole is closed by a manually operable damper, only a restricted air supply reaches the ash pit, but when the damper is moved to open the hole and close the passage h the full air supply is admitted to the ash-pit.
