Abstract

707,968. Stuffing-box substitutes. KENDICK MANUFACTURING CO,, Inc. Jan. 26, 1950 [Jan. 26, 1949], No. 2103/50. Addition to 690,988, [Group XXIX], Class 122(5) [Also in Group XXIX] A fluid seal for a rotatable shaft 100, Fig. 1, comprises two opposed seat members 104, 106 having seat portions of substantially spherical shape, and a cylindrical resilient ring 108 between the seat portions. The shaft, as shown, is the stem of a rotary valve and has the seat 104 integral therewith and the seat 106 is formed on the valve cover. A spring 112 maintains the ring in compression between the seats. In another embodiment, the stem seat 154, Fig. 4, is eccentric with respect to stem 144 and concentric rings 162, 164 are positioned between the seats 160, 154, whereby on rotation of the stem, the rings wipe an eccentric area of the seats. In a further embodiment, a ring tapered in cross-section is provided between the seats. A modified ring for use with any of the embodiments comprises an inner flexible ring 418, Fig. 8, and a heavy outer ring 420 which will carry the compressive forces between the seats.
