Abstract

The more costly electric motor drive is replaced by a clock spring drive of known construction, and which comprises a first gear driven by the spring via the shaft in a specific direction (A), which can be engaged with one or other of the two gears mounted on a common shaft which can slide in a direction parallel to the plane of rotation of the first gear and are of such dimensions that the engagement of one gear automatically disengages the other, the direction of rotation of the shaft being reversed by sliding the shaft one way or the other. The third gear is engaged with a fourth gear attached to the drive shaft of the moveable element of a tuning device.
