Abstract
648,384. Stuffing-box substitutes. PIONEER OIL SEALING & MOULDINGS CO., Ltd., and BLAKELEY, J. W, May 27. 1947, No. 14039. [Class 122(v)] In a fluid seal for a rotary shaft 12 having a non-rotatable rigid sleeve 19 with shaft clearance in sealing contact at one end with a stationary member 11, 13, and a rigid ring 20 axially slidable on the sleeve 19 by means of a splined connection 21 to effect sealing under spring pressure with an annular face 23 rotatable with the shaft 12, the space between the ring 20 and the sleeve 19 is sealed by resilient means comprising an annular rubber member 26 on the side of the ring 20 remote from the face 23, bonded or free within a rigid cup like ring 27 and spring urged into sealing contact with the ring 20 so that the consequent axial compression causes it to grip the sleeve 19 in a sealing relationship. One end of a spring 22 reacts on the member 11, 13 while the other end engages the cup-like ring 27 to effect sealing between the sleeve 19 and the ring 20 and between the ring 20 and a steel washer 23 held against a step 24 of the shaft 12 by a liner 33 secured to the shaft 12 by a nut 34. Specification 638,829 is referred to.
