Abstract

The motor driving a minute-indicator in a down counting operation which must count a finite duration is stopped when the terminal post of its control circuit is connected to "earth" potential by an electric line. A seconds-hand, rotating in synchronism with a minute-indicator, effects several revolutions during the counting operation. It is rigid with an elastic arm which, at each revolution, slides on a part of the circuit, connecting the latter to earth. This produces however stopping of the motor only at the last revolution of the seconds-hand, when a contact switch mounted in series with the sliding switch is also closed under the action of a control pin acting on an elastic blade. This pin is carried by a manually operable rocking lever which is provided with a toothed sector meshing with a pinion rigid with the minute-indicator. When the rocking lever is operated, the motor is started due to the opening of the contact and, simultaneously, the minute-indicator is brought into its starting position for counting.
