Abstract

684,779. Preventing fires. KING, Ltd., G. W. March 8, 1951 [March 13, 1950], No. 6250/50. Class 47(ii) [Also in Groups X and XXV] Fire-resisting doors 15 slidably suspended by bars 16 and rollers 17 from guide-rails 18 pivoted at 19 are held in horizontal position by a stirrup 20 which is supported by a cable 21 connected thereto by a fuzible link 24. Movement of the stirrup is limited by a fixed bracket 25. As shown, the cable 21 connects two stirrups associated with two pairs of doors on opposite sides of a doorway. The contacting edges of the doors are vertical when in the closed position and are notched at 26 and 27 for the track 11 and driving chain 14 of a travelling conveyer passing through the doorway. Switches 34 open when the doors commence to close for stopping the operation of the conveyer. The doors are guided by rollers 29, 30 and by a curved guide-piece 35. In a modification the doors are of trapezoidal shape and are provided with auxiliary panels adapted to close the doorway when the main doors are open, the connection between said panels and the main doors permitting relative movement between them.
