Abstract
719,477. Doors for resisting fluid pressure. DANKS & CO. (OLDBURY), Ltd. Jan. 30, 1953 [Feb. 1, 1952], No. 2698/52. Addition to 565,307. Class 123(1) In a modification of the closure means for a pressure vessel described in the parent Specification, the flexible packing ring is in the form of an annular member 18, Fig. 2, mounted on the complementary part 3 so that when the door 2 is in its closed position a surface 21 of the packing ring engages the inner face 22 of the door in the neighbourhood of its periphery and is pressed against it by fluid pressure within the vessel. The packing ring 18 includes a base portion 19, disposed within a groove 16 in the part 3, and a tongue 20 extending substantially radially and decreasing in thickness from a root end joined to the base portion. The tongue 20 is received in a wedge shaped groove in the door face 12. In another modification, the flexible packing ring comprises two tongues 40, 41, Fig. 4, secured to a base 39. The tongue 41 provides a seal when the vessel is subjected to negative pressure. In a further modification the packing ring 38 is disposed in a groove 37 in the door 2, Fig. 5.
