... 21,653. Holm, H. T., and Boving, K. E. Sept. 22. Regulating. - In inward-flow water turbines having pivoted guide - vanes, all the vanes are linked to a ring 6, which is hollowed as at 8 to receive rollers 9. The rollers are mounted on the ring and run on the periphery of the part 3 of the stator. A ridge on the part 3 fits the mouth of the hollow 8 and closes it. The hollow is filled with grease, either from grease cups located on the ring or by grease forced through the pipe 13. The pins on the ring 6 which form the pivots of the links 5 pass through the chamber 8, and are provided with passages by which grease from the chamber passes to the contacting surfaces of the links with the pins.
