Abstract
512,515. Piston packing; stuffing-box substitutes. ALLSOPP, A. E. Nov. 17, 1938, No. 3686. [Classes 122 (i) and 122 (v)] In a compound packing ring for a piston or stuffing-box the plane self-expanding members 16, 17; 18 and 19 are pressed axially by an expander 20 which is relatively thin axially but is radially deep and is characterized in that the corrugators are of flat-topped formation when viewed edgewise in elevation.
