.~ Motor-driven, time-controlled or oscillating (e.g., ratchet)
DEFINITION
Classification: 324/139
(under subclass 76) Subject matter having rotary motor driving means which rotate constantly, independently of the electricity being measured, or having time control means or having means which oscillate.
(1) Note. Time control means may be, for example, a clock which rotates at a constant speed or an electric synchronous motor which rotates at a constant speed. Oscillating means may be means such as an anchor escapement or a stepping ratchet.
(2) Note. This subclass relates, for example, to integrating meters wherein an element periodically oscillates at an amplitude which is determined by the quantity to be integrated (variable stroke) or at a radius which is determined by that quantity (variable radius).

103+, for demand, excess, maximum or minimum meters which provide a final indication of which time is but a factor.
116, for multi-rate registering meters which register at different rates in accordance with a function of time.
135, for oscillating measuring means in which a pulsating or reversing switch is associated with the oscillating means.
136, for variable radius type meters which utilize a rolling ball or wheel.
