- the minute hand (3) is pre-balanced by the fixed weight (25) attached to the pointer shaft.
- the vertical fine adjustment is made by the friction on the room side of the indexing mechanism (6), adjustable in both transverse directions Weight (27), the horizontal adjustment by means of the weight adjustable in the longitudinal direction on the minute hand with friction (26)
- Inute hand tip (20) sits on the extension (21) attached to the minute hand shaft (3) and angled on the room side.
- the hour timepiece (19) sits on three spacers, which in turn are firmly connected to the base plate (1).
- the second display module consisting of the step switch (28), the second hand driven by it and the second time stamp sheet, is on the end of the pipe axis (2) on the room side, in the center of the hour time sheet (19), by means of a flange with a locking screw attached, the electrical connection of the stepping mechanism (28) to the slave clock line being carried out via a small-dimensioned two-wire line which is guided through the interior of the tube axis (2).
- Figure 2 shows on a scale of 1: 1 in cross section the complete functional unit of the electronic analog slave clock 0 1200 mm.
- the plastic cylinder (2) In the center of the circular base plate (1) is the plastic cylinder (2), firmly connected to the mounting block (3), which in turn is screwed onto the wall side of the base plate (1).
- the hour tube (6) rotates smoothly in the needle bearings (4) and (5) and carries the hour hand (7) at the end on the room side and the hour wheel (8) at the end on the wall.
- the minute axis (9) rotates with ball bearings in the hour tube (6), carries the minute hand (10) at the end on the room side and the minute drive (11) on the drive side, which is fastened to the electrically conductive metal rail (12), which in turn also has a metal flange with a locking screw the minute axis (9) is electrically connected.
- the minute drive (11) engages in the change gear (13/14), which in turn is mounted in the assembly block (3) with ease and drives the hour wheel (8) in a reduction ratio of 12: 1.
- the stepping mechanism (15) is attached to the metal rail (12).
- the eccentric lever weight (17) is connected via a metal rail to the metal cylinder (18) which is stuck in the core cylinder of the ball bearing (19), the bearing cylinder of which is supported by the metal bridge (20), which in turn is screwed to the metal rail (12).
- the guide fork (21) is screwed onto the minute axis (16) of the indexing mechanism (15), which projects through the metal cylinder (18) without contact.
- rail of the eccentric lever (17) comprises.
- the transfer of the pulse change seconds pulse to the step switch (15) takes place via the ball-bearing, on the minute axis (9) contact block made of insulating material (22), in which an electrically conductive connection leads to one pole of the pulse generator from the bearing cylinder of the wall-side ball bearing (23) and the core cylinder is seated on the electrically conductive minute axis (9), which in turn is electrically connected to one pole of the stepping mechanism (15) via the metal rail (12).
- the other pole of the stepping mechanism (15) has an insulated wire with a metal cylinder, which is electrically insulated from the minute axis (9) and is stuck in the core cylinder of the room-side ball bearing (24).
- the bearing cylinder of the ball bearing (24) is connected to the other pole of the pulse generator via an insulated line.
- the pointer shaft and tip of the hour hand (7) are balanced with the counterweight (25).
- the semicircular segmental adjustment weight (26) of the minute hand (10) is rotatably riveted on the circular metal plate (27) and enables the fine adjustment of the minute hand (10).
- the outer weight (26) is visually covered on the room side by the circular disc (28).
- the horizontal fine adjustment of the minute hand (10) is carried out on the pointer shaft on the back of the pointer tip by moving the dusting weight (29), which is attached to the sliding clip (30) which rests on the pointer shaft of the minute hand (10) with spring pressure.
- Figure 3 shows this on a reduced scale 1: 3 in front and side view
- Protective housing '31 in which three spacer bolts (32/33/34) for mounting the base plate (1) with the complete, ready-to-connect functional unit are screwed.

Abstract
Les horloges secondaires électroniques analogiques actuelles nécessitent, pour l'entraînement des aiguilles des minutes et des heures, un mécanisme électronique pas à pas intégré à chaque aiguille. L'invention a pour objet de développer et de simplifier la conception du système en faisant avancer les deux aiguilles au moyen d'un mécanisme pas à pas intégré à l'aiguille des minutes uniquement. Le dessin de la figure montre l'entraînement mécanique de l'aiguille des heures (14) par l'entraînement des minutes (22) fixé sur l'aiguille des minutes (3), par l'intermédiaire d'une roue de minuterie (23) et de la roue des heures (15) avec un rapport de réduction de 12:1. L'exemple d'exécution convient spécialement pour les horloges secondaires électroniques analogiques commandées par radio à "seconde sautante" et "minute glissante".Current analogue electronic secondary clocks require, for driving the minute and hour hands, a stepping electronic mechanism integrated into each hand. The object of the invention is to develop and simplify the design of the system by advancing the two hands by means of a stepping mechanism integrated into the minute hand only. The drawing of the figure shows the mechanical drive of the hour hand (14) by the minute drive (22) fixed on the minute hand (3), via a timer wheel ( 23) and the hour wheel (15) with a reduction ratio of 12:1. The exemplary embodiment is especially suitable for analogue electronic radio-controlled "jumping second" and "sliding minute" secondary clocks.
