Zum Verschieben der Scheibe 39 dient eine mit Flanschen versehene Scheibe 42, Fig. 8, die lose um die Nabe der Scheibe 39 gelegt.. ist. Zwischen den Scheiben 39 und 42 liegt ein Kugellager, das von Laufringen 43, Kugeln 45 und einem Führungsring 44 gebildet wild. An die Scheibe 42 ist ein Bügel 46 angelenkt, der auf einer in der Wandung des Gehäuses 2 drehbaren Schwingwelle. 47 befestigt. ist. An einem Ende dieser Schwingwelle sitzt ein Arm 48, der unten durch eine Zugstange 49 mit einer Mutter 50 verbunden ist, welche auf einer mit Handrad 52 versehenen Schraubenspindel 51 sitzt.
Mittels dieses Handrades kann die Mutter längs einer

der Welle 47, des Bügels 46 und der Scheibe 42 verschoben wird und einen grösseren oder geringeren Druck auf die -Winkelhebel 38 und die Federn 37 ausübt.
Die Mutter 50 wird gegenüber ihrer Skala so eingestellt, dass die Schallplatte die für die Wiedergabe erforderliche Geschwindigkeit erhält und auch der Film mit entsprechender Geschwindigkeit abläuft.,
Wenn sich die Geschwindigkeit der Welle 7, 8 ändeit, so wird diese Veränderung durch das Tachometer angegeben. Entsprechend dieser Angabe wird die Scheibe 39 von dem Hand-

EMI2.1
A flanged disk 42, FIG. 8, which is loosely placed around the hub of the disk 39, serves to move the disk 39. Between the disks 39 and 42 is a ball bearing formed by races 43, balls 45 and a guide ring 44. A bracket 46 is hinged to the disk 42 and is mounted on an oscillating shaft rotatable in the wall of the housing 2. 47 attached. is. At one end of this oscillating shaft sits an arm 48 which is connected at the bottom by a tie rod 49 to a nut 50 which sits on a screw spindle 51 provided with a handwheel 52.
By means of this handwheel, the mother can along a

the shaft 47, the bracket 46 and the disk 42 is displaced and exerts a greater or lesser pressure on the angle lever 38 and the springs 37.
The nut 50 is set in relation to its scale so that the record receives the speed required for playback and the film also runs at the corresponding speed.
If the speed of the shaft 7, 8 changes, this change is indicated by the speedometer. According to this information, the disc 39 is held by the hand
