KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine weitere Ausbildung der durch Patent 231309 geschützten Vorrichtung zum Anpressen der Zeichnungen und des Pauspapiers an den Glaszylinder eines Lichtpausapparates mittels Decktuches. Während das Decktuch nach dem Hauptpatent an einer von drehbar angeordneten Lagerarmen getragenen Leiste angebracht ist und um den festliegenden Zylinder gezogen wird, soll hier die Leiste an den drehbar gelagerten Zylinder befestigt werden.The invention relates to a further embodiment of that protected by patent 231309 Device for pressing the drawings and the tracing paper onto the glass cylinder a blueprint machine using a blanket. While the cover sheet according to the main patent on one of rotatably arranged Bearing arms worn bar is attached and drawn around the fixed cylinder the bar should be attached to the rotatable cylinder here.
Durch die neue Anordnung wird das Einlegen und Herausnehmen des Kopiergutes erleichtert, indem der Zylinder mit dem Decktuch gedreht wird. Durch das Aufwickeln des Decktuches auf eine Walze, wobei der Glaszylinder sich mit zurückdreht, werden die Zeichnungen wieder freigegeben.The new arrangement makes it easier to insert and remove the copied material, by rotating the cylinder with the cover sheet. By winding it up of the cover sheet on a roller, whereby the glass cylinder rotates back with it, the Drawings released again.
Die Zeichnung zeigt schematisch den an sich bekannten Glaszylinder eines Lichtpausapparates mit dem Decktuch und deren Bewegungsvorrichtungen. The drawing shows schematically the known glass cylinder of a blueprint apparatus with the cover sheet and its movement devices.
Der Glaszylinder α ist in bekannter WeiseThe glass cylinder α is in a known manner
drehbar gelagert und wird mittels Kurbel b und Kette c mit dem an den Stirnlagern β, f durch eine Schiene g befestigten Decktuch h in Richtung d in Umdrehung versetzt, wodurch die zwischen Tuch und Glas gelegte Zeichnung mit dem Pauspapier herumgenommen und eingespannt wird.rotatably mounted and is rotated by means of crank b and chain c with the cover cloth h attached to the end bearings β, f by a rail g in direction d , whereby the drawing placed between cloth and glass is taken around with the tracing paper and clamped.
Das Entfernen der fertigen Pausen erfolgt durch Aufdrehen des Decktuches auf die Welle i mittels Kurbel k in Richtung I. The finished pauses are removed by turning the cover sheet onto shaft i using crank k in direction I.
Die Befestigung des Decktuches an den Enden erfolgt in gleicher oder in ähnlicher Weise wie beim Hauptpatent. Das Zurückgehen des Tuches und Zylinders nach erfolgtem Einlegen und Spannen wird durch eine Sperrklinke gehindert.The fastening of the cover sheet at the ends is carried out in the same way or in a similar manner Way as with the main patent. Returning the towel and cylinder after done Insertion and tensioning is prevented by a pawl.
