Abstract
532,992. Stuffing-box substitutes. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Sept. 29, 1939, No. 26904. Convention date, Oct. 1, 1938. [Class 122 (v)] Labyrinth packing for a turbine spindle comprises overlapping collars 13, 17 carried by the housing 10 and the spindle 11 respectively, the collars 17 having stepped radial surfaces 18. Each of the fixed collars 13 has a number of coaxial circular sealing-strips 19 of relatively thin flexible metal extending laterally from one face and providing close clearances with the stepped surfaces 18. Single sealing-strips 22 of relatively heavy section extend radially from the housing and co-operate with axial surfaces 26 at the circumference of the rotatable collars. Similar sealing-strips 27 extend radially from the spindle and co-cperate with the axial end surfaces of the fixed collars, The sealing-strips are secured in grooves by caulking- strips 2.1, 24, 29. The radial sealing-strips 22, 27 may be replaced by pairs of strips of lighter material, which co-operate with stepped surfaces on the spindle and on the axial surfaces 26.
