Aufnahme- und Wiedergabekamera, welche an einem Seil aufgehängt ist. Bei bekannten Kameras dieser Art ist das Gewicht der Kamera durch ein Gegengewicht ausgeglichen.Recording and playback camera, which is suspended on a rope. At acquaintances Cameras of this type, the weight of the camera is balanced by a counterweight.

Demgegenüber ist zum Ausgleich des Kameragewichts nach der Erfindung das Seil an zwei miteinander verbundenen Schraubenfedern befestigt, von denen die eine innerhalb der anderen angebracht ist, so daß beiIn contrast, according to the invention, the rope is used to compensate for the weight of the camera attached to two interconnected coil springs, one of which is inside the other is attached so that at

der Verstellung der Kamera zuerst die eine Feder gespannt wird, die dann bei einer gewissen Spannung die mit ihr verbundene! andere Feder beeinflußt und diese ebenfalls spannt. Der Auszug beider Federn genügt, um die bei Vergrößerungsvorrichtungen übliche VersteEungsmöglichkeit durchzuführen. Die Zeichnung zeigt einen Schnitt durch das Gestell der Kamera. Innerhalb des un-the adjustment of the camera first one Spring is tensioned, which then at a certain tension the connected to it! influences other springs and also tensions them. The extraction of both springs is sufficient in order to carry out the adjustment possibility that is usual with enlarging devices. The drawing shows a section through the frame of the camera. Within the un-

IQ teren Teiles des Kameragestelle's ist eine· Schraubenfeder α am unteren Teile c eines Rohres b befestigt, während das obere Ende der Feder mit einem Drahtseil verbunden« ist, an welchem die Kamera hängt. Das Rohr b wird von einer zweiten Federt umschlossen, die ebenfalls am Rohr b, und zwar auf der entgegengesetzten Seite wie die innerhalb des Rohres befindliche Feder, befestigt ist, während das andere Ende am Fuße des Gestelles angehängt ist.In the lower part of the camera frame, a helical spring α is attached to the lower part c of a tube b , while the upper end of the spring is connected to a wire rope from which the camera hangs. The tube b is surrounded by a second spring, which is also attached to the tube b, on the opposite side as the spring located inside the tube, while the other end is attached to the foot of the frame.

Das Rohr b dient nicht nur zur Befestigung der beiden Federn, sondern verhindert auch beim Zurückgehen der gespannten Federn deren gegenseitige Berührung und ein störendes Ineinandergreifen der einzelnen Spiralen.The tube b is not only used to fasten the two springs, but also prevents mutual contact and a disruptive interlocking of the individual spirals when the tensioned springs go back.
