Abstract
347,871. Steam turbines. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees, of Dempster, J. A. ; 1382, Myron Avenue, Schenectady, New York, U.S.A.) April 23, 1930, No. 12559. Convention date, April 24, 1929. [Class 110 (iii).] Leakage-preventing devices.-The packing-ring 17 attached to a rotor 5 between blade carrying wheels 7 to coact with an interstage diaphragm 8 is formed of segments 20 having recesses 18 adapted to engage flanges 12 on the rotor. The segments ate notched at 19, and corresponding notches 13 are formed at one point in the rotor flanges. The packing-ring is built up by inserting the segments radially at the notches 13, and then moving them circumferentially in the groove. The last segment is locked by a screwed stud 23. The coacting surfaces are serrated and spaces are left about the segments to reduce transfer of heat to the rotor.
