Revolution Counter
This is an old form of revolution counter. The gearing consists of a worm and worm-wheel, together with a train of spur-wheels for reducing the speed, and three dials over which four indexes move continuously but not all in the same direction, so that the reading is difficult, particularly at high speeds.
