Handschauapparat für RoIIfilmbänder.Handheld viewing device for roll film tapes.

Patentiert im Deutschen Reiche vom 31. Oktober 1922 ab.Patented in the German Empire on October 31, 1922.

Handschauapparate für RoIIfilmbänder, bei denen die Filmbänder über zwei übereinandergelagerte Spulen geführt sind, zwischen denen das die Linse enthaltene Schaurohr angeordnet ist, sind bekannt. Bei diesen Apparaten sind die Filmbänder in allseitig geschlossene Gehäuse einzulegen, welche mit besonderen spiralig eingezogenen Wandteilen zur Bandführung versehen sind. Diese Bauart ist umständlich und kostspielig; außerdem besteht dort für die Filmbänder die Gefahr des jZerkratzens und Unbrauchbarmachens durch die spiral ig eingezogenen Gehäuseteile.Handheld viewing devices for roll film tapes, in which the film tapes are superimposed over two Coils are guided, between which the viewing tube containing the lens is arranged is known. In these devices, the film tapes are in housings that are closed on all sides to be inserted, which have special spiral wall parts for belt guidance are provided. This type of construction is cumbersome and expensive; In addition, there is a risk of scratching the film tapes there and rendering it unusable by the spirally drawn-in housing parts.

Diese Mängel beseitigt der Erfindungsgegenstand durch seine einfache Bauart, wo- nach die beiden Spulen für die Filmbänder mit seitlichen, weit überragenden Flanschen versehen und freischwebend in am Linsengehäuse befestigten Armen gelagert sind. Hier können Flilmbänder großer Länge Verwendung finden, ohne daß die Gefahr des Zerkratzens durch Apparateteile besteht;The subject of the invention eliminates these deficiencies through its simple design, where- after the two reels for the film tapes with side, far protruding flanges provided and are mounted freely floating in arms attached to the lens housing. Long-length film tapes can be used here without the risk of being scratched by parts of the apparatus;

auch ist die Auswechselung der Bänder, deren Enden nur in einen Spalt der starken Spulen eingeschoben werden, einfacher.also is the replacement of the ribbons, the ends of which are only in a gap of the strong coils be inserted, easier.

Die Zeichnung erläutert den Erfindungsgegenstand in einer Ausführungsform durch Abb. ι im Horizontalschnitt,The drawing explains the subject matter of the invention in one embodiment Fig. Ι in horizontal section,

Abb. 2 in Draufsicht undFig. 2 in plan view and

Abb. 3 in Seitenansicht.Fig. 3 in side view.

An einem Drahtgestell α sind übereinanderliegend Rollen b, c drehbar gelagert, und zwischen den Rollen trägt das Gestell α ein feststehendes Gehäuse d, in dessen vorderem Teil eine Linse e verschiebbar angeordnet ist, während das hintere offene Gehäuseende mit seitlichen Führungen f für ein Filmband g versehen ist. Letzteres wird mit seinen Enden an den Rollen b, c lösbar befestigt, so daß es leicht ausgewechselt werden kann. Rollers b, c are rotatably mounted on a wire frame α, one above the other, and between the rollers the frame α carries a fixed housing d, in the front part of which a lens e is slidably arranged, while the rear open end of the housing has lateral guides f for a film tape g is provided. The latter is releasably attached with its ends to the rollers b, c , so that it can be easily replaced.

Beide Rollen b, c sind mit Handhaben h versehen, mittels welcher sie von Hand verdreht werden können, um den Film von der einen Rolle auf die andere oder zurückwickeln zu können. Gegen das andere Ende der Rollen b, c wirken Hemmungsfedern i, damit die Rollen b, c in jeder gegebenen Lage stehen bleiben und das Filmband die erforderliche Spannung behält.Both rolls b, c are provided with handles h by means of which they can be turned by hand in order to be able to wind the film from one roll to the other or back. Inhibiting springs i act against the other end of the rollers b, c so that the rollers b, c stop in any given position and the film tape maintains the required tension.
