Kaiser's five figure revolution counter, 1883

Kaiser's five figure revolution counter, 1883

This is a five-figure counter on the intermittent system, patented by Mr. A. Kaiser in 1883. The figures are placed on the peripheries of wheels, and the movement of the unit figure wheel is effected, as in Watt's and many other counters, by a reversed escapement; a crankpin engaging with a slotted lever secured to the pallets imparts the necessary reciprocating motion to the latter. A single tooth attached to the axis of the first wheel drives, intermittently, a wheel with ten projecting teeth, and so on throughout the series. Each of the figured wheels is locked during the intervals between the step movements by a projecting rim, on the preceding driving wheel, passing between the over-hanging teeth.
