Abstract

618,729. Indicating vibrations. SMITH, A. E., [Representative of SMITH, W.]. Nov. 22, 1946, No. 34661. [Class 106 (iv)] [Also in Group XXVII] In apparatus for indicating critical speeds, relative motion between a drum or pulley driven by the engine crank-shaft and a flywheel closes a circuit which operates a warning device. The drum 1 is connected to the front of the crank-shaft and the flywheel 2 is carried on ball bearings 31 and driven by a helical spring 4. A micro switch 13 is operated from a pin 21 on the flywheel through a lever 61, a bellcrank lever 51, 52 and an adjustable spring- loaded pin 8.
