Abstract

532,348. Stuffing-box packing. HALL & HALL, Ltd., and HALL, E. J. Aug. 18, 1939, No. 23885. [Class 122 (v)] Relates to packing of the kind comprising a channelled ring b, Fig. 1, which is expanded by a ring a having a convex upper surface and spaces formed between foot-portions, to admit fluid pressure to the underside of the ring. According to the invention, the foot-portions are extended circumferentially and radially from the inner to the outer periphery in order to increase their strength, so that the spaces c between them are left relatively narrow, and apertures d are formed through the ring leading to the channel in the packing-ring b.
