Abstract

703,078. Stuffing box substitutes. FERGUSON, Ltd., H. Nov. 29, 1951 [Nov. 14, 1950], No. 27779/50. Class 122 (5). [Also in Group XXIX] A seeing assembly 6 between the ram 5 and cylinder assembly is retained in a 1 of a hydraulic jack (see Group XXIX) comprises sintered bronze bearing rings 16 with an interposed rubber packing 18 having a steel ring 17 bonded thereto. The a counterbore 13 by a split ring 14. The ram engages -a sleeve 19 at the end of the stroke and serves to -increase the tightness of the seal; the sleeve 19 bearing on the inner ring 16.
