Abstract

111,897. British Thomson - Houston Co., (General Electric Co.). Dec. 12, 1916. Stuffing-boxes, substitutes for.- Packing for the shafts of turbines &c. consists of a conical member 12 formed with cylindrical surfaces which co-operate with stationary rings 16 to form a labyrinth packing. The member 12 may also carry rings 14 which co-operate with the radial surfaces of the rings 16 to form a second labyrinth packing. Alternatively, the inner member 12 may be stationary and the outer member rotate. Reference has been directed by flic Comptroller to Specifications 8547/05 and 17201/13.
