YereeMuß für Äufnahmekinematographen.YereeMust for recording cinematographs.

Patentiert im Deutsches Reiche vom II. Juli 1822 sPatented in the German Empire on July 2nd, 1822 p

Es sind bereits Verschlüsse für Äufnahmekinematographen bekannt, bei denen zur Verstellung der Schlitzweite ein einschaltbares Organ betätigt werden muß, das automatisch bei bestimmten Stellungen der Verschlußflügel zueinander in seine ursprüngliche Lage zurückkehrt und die Flügel in ihrer jeweiligen Stellung gegen Verdrehung sichert. Bei diesen Verschlüssen ist das einschaltbare Organ an den VerscMußflügeln angeordnet. Es kannThere are already closures for recording cinematographs known, in which a switchable organ must be actuated to adjust the slot width, which automatically in certain positions of the shutter wing to each other returns to its original position and secures the wings against rotation in their respective positions. With these Closures, the switchable organ is arranged on the VerscMußflügel. It can

demnach der Verschluß nur bei geöffnetem Gehäuse und bei ruhendem Verschluß verstellt werden.accordingly, the lock is only adjusted when the housing is open and when the lock is at rest will.

Die Erfindung betrifft eine Vorrichtung zum Verstellen der Schlitzweite an Objektivverschlüssen für Aufnahmekinematographen, bei der die beiden Verschlußflügel α und b in bekannter Weise durch Reibung, welche durch eine Federe bewirkt werden kann oder auchThe invention relates to a device for adjusting the slot width on lens shutters for recording cinematographs, in which the two shutter wings α and b are produced in a known manner by friction, which can or may also be caused by a spring

ίο durch jede andere Kupplung, z. B. durch Klauenkupplung o. dgl., verbunden sind. Um eine Verstellung der Schlitzweite des Verschlusses zu bewerkstelligen, ist nach der Erfindung ein einschaltbares Organe? an der dem Verschluß gegenüberliegenden Gehäusewand angeordnet, welches bei der Betätigung in die Laufbahn der Scheibe α tritt und deren Bewegung sperrt. Eine Verstellung der Scheibe α gegenüber der auf der Verschluß-ίο by any other coupling, e.g. B. by claw coupling o. The like. Are connected. In order to adjust the slot width of the shutter, according to the invention, a switchable organ? arranged on the housing wall opposite the closure which, when actuated, enters the track of the disk α and blocks its movement. An adjustment of the disc α compared to the one on the closure

*o welle fest angeordneten Scheibe & kann nur während der Bewegung des Triebwerkes oder der Scheibe b vorgenommen werden. Das die Scheibe« sperrende Organd kehrt jedesmal unmittelbar nach seiner Betätigung automatisch in seine ursprüngliche Lage zurück. Um die Schlitzweite des Verschlusses in bestimmten Abständen verstellen zu können, sind auf der Scheibe b Angaben über die gebräuchlichsten Schlitzweiten vorgesehen, welche durch eine öffnung e der Scheibe a ablesbar sind.* o shaft fixed disk & can only be made while the engine or disk b is moving. The organ d which blocks the disk automatically returns to its original position immediately after it has been actuated. In order to be able to adjust the slot width of the closure at certain intervals, information about the most common slot widths is provided on the disk b , which can be read through an opening e of the disk a.
