Bei der Ausführungsform gemäss Fig. 8-10 sitzt die Exzenterscheibe 48 wieder mit einem Schlitz 49 auf ihrer Welle 50, welch letztere in dem Schlitz nach Art eines Gehäuses 51 ausgebildet ist und ein Zahnrad 52 trägt. Dieses Zahnrad besitzt auf jeder Seite einen exzentrischen Zapfen 53 und greift mit diesen Zapfen in Lagerstücke 54 ein, welche in Schlitzen 55 der Exzenterscheibe parallel zur Achse derselben verschiebbar sind. Durch die hohle Welle 50 des Exzenters geht eine Zahnstange 56j welche als Rotationskörper ausgeführt ist, sodass sie undrehbar stehen bleiben kann, während sich das Zahnrad in der Exzenterebene um sie herumbewegt.
Durch Verschiebung der Zahnstange 56 in ihrer Längsrichtung wird das Zahnrad 52 gedreht und dadurch infolge der exzentrischen Zapfen 53 die Exzenterscheibe 48 senkrecht zu ihrer Welle verschoben, wobei gleichzeitig die Lagerstücke 54 in den Schlitzen 55 gleiten. In der Fig. 9 sind die beiden äussersten Lagen der exzentrischen Zapfen punktiert angedeutet, welche der Nullstellung bezw. dem grössten Exzenterhub entsprechen. Die Verschiebung der Zahnstange 56 kann durch einen Handhebel oder sonstwie geschehen.

In the embodiment according to FIGS. 8-10, the eccentric disk 48 is seated again with a slot 49 on its shaft 50, the latter being formed in the slot in the manner of a housing 51 and carrying a gear 52. This gear wheel has an eccentric pin 53 on each side and engages with these pins in bearing pieces 54 which are displaceable in slots 55 of the eccentric disk parallel to the axis of the same. A toothed rack 56j, which is designed as a rotating body, goes through the hollow shaft 50 of the eccentric so that it can remain stationary while the gear wheel moves around it in the eccentric plane.
By displacing the rack 56 in its longitudinal direction, the gear 52 is rotated and, as a result of the eccentric pins 53, the eccentric disk 48 is displaced perpendicular to its shaft, the bearing pieces 54 sliding in the slots 55 at the same time. In Fig. 9, the two outermost positions of the eccentric pin are indicated by dotted lines, which respectively the zero position. correspond to the largest eccentric stroke. The shifting of the rack 56 can be done by a hand lever or otherwise.
