Abstract

520,348. Piston packing. GUTHRIE, C. G. Oct. 19, 1938, No. 30200. [Classes 122 (i) and 122 (v)]. A piston 11, Fig. 1, is formed with undercut grooves, 12a, 12b, in which are fitted split wedging rings 14a, 14b, which secure a packing ring 16 in position. The ring 16 stands proud of the wedging rings and expansion of the wedging rings restrains by friction the expansion of the ring 16. The rings may be fitted in a carrier ring fitted in a groove in the piston, thus enabling the life of an old piston to be extended. As shown in Fig. 4 a gland 28 for a piston rod 29 is fitted with two sets of wedging and wedged packing members constructed as described above. Specification 484,621 is referred to.
