Abstract

679,762. Stuffing-boxes. AVERY-HARDOLL, Ltd. Feb. 23, 1951 [May 22, 1950], No. 12796/50. Addition to 670,666, [Group XXVIII]. Class 122(v) [Also in Group XXVIII] A shell 97 retained in position on a valve member 58 of a pipe coupling (see Group XXVIII) carries round - section packing rings 99, 105, the ring 105 being confined between a flange of the shell and a washer 101 that engages a shoulder 100 and is acted upon by springs 102 to urge the shell outwardly.
