Abstract

591,320. Speed indicators. MARSH, T. E. E. May 16, 1945, No. 12247. [Class 106 (iii)] [Also in Group XXXVII] On the attainment of sufficient speed of a driving shaft 2, fluid-friction between vanes 10 thereon and the walls of a liquidcontaining drum 1 rotatable on the shaft, causes the drum to be dragged round to close electric contacts 8. The drum may close alternative contacts when reversely rotated.
