Abstract

565,307. Pressure resisting covers. DANKS & CO. (OLDBURY), Ltd., E., WHITE, F. G. S., and DURRANS, A. May 5, 1943, No. 7103. [Class 123 (i)] A pressure-resisting cover 2 forming a seal with the rim 3 of a vessel by means of a flexible packing ring 4, is provided with a rotatable ring 6 formed with spaced locking tongues 7 which co-operate with similar tongues 5 on the rim 3 to lock or release the cover. The packing ring 4 is provided with a wedge-shaped tongue 21, extending inwards, which is engaged by the part 11 of the cover and is pressed against it by the internal fluid pressure. The ring 6 is rotated by means of a tommy bar 27 engaging a fixed pivot 25 and an abutment 26 on the ring. The cover is mounted on hinge pins 32, 33 having bearings respectively in brackets 34, 35 on the part 3, and in the hinged arms 36 which are rotatable on the pin 32. Further hinged arms 38 are mounted on the pin 33 and on a rod 41 carried by the cover. Longitudinal adjustment of the rod 41 is effected by screw 43. The door is, therefore, rotatable about the hinge pins 32 and 33. To prevent opening while the vessel is under pressure, the operating lever 51 of a pressure-relieving valve 46 carries an extension 52 engaging slots in the rim 3 and ring 6 when the lever is in the closed position. Rotation of the ring 6 to the opening position is prevented until the extension 52 is disengaged from the ring 6 and the valve opened. In a modification, the cover is not hinged, but is provided with lifting gear. In another modification, Fig. 7 (not shown), the packing ring is provided with two wedge-shaped tongues engaging the cover, one subject to internal pressure and the other to atmospheric pressure when used with a vessel which is under vacuum.
