- 13 - ARTICULATED SEAL FOR ROTATING CYLINDER SUCH AS KILN OR THE LIKE ABSTRACT OF THE DISCLOSURE A seal for use in sealing an annular opening between a stationary member and a rotating cylinder telescopically arranged in the stationary member, the seal comprising an annular ring member circumscribing the cylinder adjacent the stationary member and closing the annular opening. The seal comprises weighting means extending axially away from a back side of the ring member to provide a counterweighting effect which causes a tilting of the ring member, whereby said tilting and the rotation of the cylinder moves the ring member into engagement with the stationary member to substantially seal the annular opening, all in accordance with the teaching of United States patent number 3,042,389. In accordance with the present invention, the annular ring member is divided into a plurality of circumferentially extending segments in which adjacent segments are pivotally connected to each other to permit articulation of the segments to accommodate "out-of-round" portions of the rotating cylinder.
