Abstract
625,866. Stuffing-box substitutes. PLESSEY CO., Ltd. Jan. 13, 1947, No. 1118. Convention date, Jan. 11, 1946. [Class 122(v)] In a sealed control shaft construction for an adjustable electrical device comprising a bushing 15, a control shaft 14 circumferentially grooved at 17 and extending through the said bushing, the inner portion of the groove being located within the bushing and the outer portion of the groove extending outside the bushing, a clinch ring 20 secured to the outer grooved portion to prevent longitudinal movement of the shaft with respect to the bushing, and a sealing washer 21 of rubber or other resilient material seated on the inner grooved portion, the bushing having a conically shaped tapered recess 24 at the inner end thereof to force the washer gradually into sealing position as the central shaft and bushing are assembled, the peripheral ports of the washer are forced into contact with the bushing by the resiliency of the washer material to seal the control shaft thereby.
