Abstract

618,970. Hydraulic packing. WALKER & CO., Ltd., J., WATSON, T. F., TANK, W. T., and BONSEY, C. H. Aug. 30, 1946, No. 26190. [Classes 122 (i) and 122 (v)] A hydraulic packing for a ram e in a cylinder d comprises a U-shaped ring b, the lips of which are pressed apart to effect sealing by a header packing ring a pressed axially by a number of springs l contained in counterbores k<1> and compressed by flat heads n on pins m passing through the springs and holes k and having riveted heads o to retain the springs when the packing is removed from the cylinder.
