Abstract
982,888. Facilitating fire-fighting. JAMES GREEN DEVELOPMENTS Ltd. Oct. 17, 1963 [Oct. 4, 1962], No. 37533/62. Heading A5A. [Also in Division F4] A door unit for gaining access to ventilation ducting 17 (to extinguish fires therein &c.) comprises a tubular body 10 closed at one end by a readily frangible panel 18 and having its other end closed by a pivoted door 14 operable by pressure acting over the face nearer to the frangible panel but not by pressure acting over the face remote therefrom. The body 10, which is of square cross-section, is secured over a hole in the ducting 17 by a flange 16 which may be positioned at any point along the length of the body. The panel 18, which may be of asbestos or heat-proof glass, is removably secured to the body 10 by bolts 12. The door 14, which comprises a wire gauze panel hinged at 13, is prevented from opening into the body 10 by an inner tube 15, and may be urged towards the panel 18 by weights or springs.
