Abstract

759,666. Piston, stuffing-box and jointmaking packing. COLLINS, J. E. Nov. 8, 1954 [May 5, 1954], No. 32261/54. Classes 122(3) and 122(5) [Also in Group V] Moulded rubber sealing rings have the shapes shown at 105 and 205, Figs. 3 and 4. In Fig. 3 the moulding flash is formed at C and D, i.e. not at the sealing surfaces A, A. In Fig. 4 also the flash is not at the sealing surfaces B, B but at E, F. The horseshoe-section ring of Fig. 4 may have integral' reinforcing webs extending between the legs of the horseshoe.
