Abstract: 981,771. Fire fighting &c. NORSTEL & TEMPLEWOOD HAWKSLEY Ltd. Aug. 19, 1963, No. 32746/63. Heading A5A. [Also in Division F4] A roof ventilator comprises a cowling 1 containing a pair of dampers 8 movable between open and closed positions (shown in full and dashed lines, respectively, in Fig. 2) by a mechanism including a fusible link which, in case of fire, allows the dampers to move to a third position which allows direct communication between the interior and exterior of the building. The dampers 8 are pivoted at 9 below a baffle 4 which extends between the end walls 3 of the cowling. Sectors 11 are attached to the ends of each damper and limit opening movement of the latter by engagement with the tops 12 of housings 5 at the ends of the baffle 4. In the closed position the dampers 8 abut elongated plates 15 pivoted to a throat member 6 of the ventilator about axes 16 offset towards the dampers. The dampers are operated by arms 20 joined by an aluminium yoke 22 actuated by a pneumatic cylinder 23 and a piston including a cadmium plated mild steel tube 24 containing a fusible link 25. The operating mechanism is normally hand operated but in the event of intense heat the link 25 fuses allowing the dampers 8 to fall, pivoting the plates 15, to a position in which they hang freely, Fig. 3 (not shown), thus giving direct communication between the interior and exterior of the building.
