Description
Ρλτενϊ-Αμ Sprüche:Ρλτενϊ-Αμ Proverbs:
I. Selbsttätiger Umschalter zum Aus- und Einkuppeln eines kinematographischen \rorführungsapparates, bei der durch ein Schneckenrad eine Gewindeachse in langsame Rechts- oder Linksdrehung versetzt wird, wodurch sich ein auf der Gewindeachse befindliches Mittelstück auf- oder abwärts bewegt, das mittels federnder Anschläge auf einen Kupplungshebel einwirkt, dadurch gekennzeichnet, daß das Schnekkenrad von einer an der oberen Zahnrolle befindlichen Schnecke gedreht wird und eine an dem Mittelstück befestigte hohle Welle mitnimmt, in welcher eine Distanz- 8t stange geführt ist.I. Automatic changeover switch for disengaging and engaging a cinematographic \ r guide apparatus, in which a worm wheel sets a thread axis in slow right or left rotation, whereby a center piece located on the thread axis moves up or down, which is opened by means of resilient stops a clutch lever acts, characterized in that the worm wheel is rotated by a worm located on the upper toothed roller and takes along a hollow shaft attached to the center piece in which a spacer rod is guided.
2. Selbsttätiger LTmschalter nach Anspruch i, dadurch gekennzeichnet, daß die in der hohlen Achse geführte Distanzstange vermittels eines konischen Ge- 8| windes mit Muttern entsprechend der vorzuführenden Filmlänge einstellbar ist.2. Automatic L T m switch according to claim i, characterized in that the spacer rod guided in the hollow axis by means of a conical Ge 8 | wind is adjustable with nuts according to the film length to be shown.
3. Selbsttätiger Umschalter nach Anspruch 2, dadurch gekennzeichnet, daß der Kupplungshebel durch die federnden An- g schlage nach oben oder nach unten gedrückt wird, wodurch einmal der Vorführungsapparat ein- und die Rückrollung ausgeschaltet wird oder umgekehrt.3. Automatic changeover switch according to claim 2, characterized in that the The clutch lever is pushed up or down by the resilient stop is, whereby the demonstration device is switched on and the rollback is switched off or vice versa.
4. Selbsttätiger Umschalter nach Anspruch 3, dadurch gekennzeichnet, daß der Kupplungshebel, um ein plötzliches Ein- und Ausschalten zu bewirken sowie ein Rückschnellen zu verhindern, vermittels eines von einer Feder vorgedrängten, mit 1 schrägen Gleitflächen versehenen Sperrstiftes festgehalten wird.4. Automatic changeover switch according to claim 3, characterized in that the Clutch lever to cause a sudden on and off as well as to prevent bouncing back by means of a locking pin pushed forward by a spring and provided with 1 inclined sliding surfaces is being held.
