Abstract
987,913. Flue dampers. IDEAL-STANDARD Ltd. March 18, 1963 [April 5, 1962], No. 13174/62. Heading F4W. A chimney throat control mechanism comprises an adjustable throat restrictor plate 11 and a damper 21 for controlling the back boiler 2, flue draught in the flue 3, the damper control acting so that it can move the restrictor plate towards its closed position when the damper is opened. The curved throat restrictor plate is directly operable by means of a tool engaging the aperture 30 in lug 29 and may be moved until either the stop 12 engages the canopy 8, thus ensuring a minimum throat area of five square inches, or the restrictor plate engages the adjustable stop 14. The restrictor plate is pivoted about a rib 9 upon the top 5 of the back boiler by means of a hook 19, a second hook being provided upon the restrictor plate for pivotal engagement with the damper 21, which is fitted with an operating handle 23 passing through a hole 27 in the restrictor plate. The damper and restrictor plate are formed as a unit to facilitate removal when servicing and cleaning.
