  • Patent number: 4175607
    Abstract: A latch plate for an automatic fire damper intended to be used in ductwork to close such ductwork in the event of fire is formed as a unitary structure. Such a latch plate comprises mutually perpendicular end and side flanges and is integrally formed on its side flange with a transversely projecting, arcuate-sectioned tongue about which there can be wound a spool type tension spring which is operative to move a closure or shutter of such a damper into its closed position on fusion of a mechanical catch mechanism normally holding such a closure in its open position. The side flange of the latch plate is formed with a lateral cam surface along which a terminal blade member of the closure rides as it moves into its closed position and such surface is formed with a pair of ribs on the shutter when that shutter reaches its fully closed position so then releasably to hold the shutter in such closed position, and a novel blade for use in such a fire damper having one symmetrical and one assymetrical hinge part.
