KLASSE 67; Photographie.CLASS 67; Photograph.
Das auf beiliegender Zeichnung dargestellte Copirbrett besteht aus zwei Theilen A und B, welche durch zwei an den Seiten angebrachte Scharniere c zusammengehalten werden.The copier board shown in the accompanying drawing consists of two parts A and B, which are held together by two hinges c attached to the sides.
Die Scharniere sind so construirt, dafs sie ein Zusammenklappen der Bretter verhindern und beim Oeffnen keinen Spalt bilden. An den Bretttheilen befinden sich an den beiden Längsseiten je ein beweglicher Drahtbügel h, an dessen beiden Enden nochmals kleine Bügel ζ als Niederhalter angebogen sind. Diese Niederhalter i werden durch die doppelt, d. h. nach zwei Seiten gewundene Spiralfeder s auf das Brett niedergedrückt, wodurch das Aufpressen der zu copirenden photographischen Platte oder des Negativs bewirkt wird.The hinges are so constructed that they prevent the boards from collapsing and do not form a gap when they are opened. On the two long sides of the board parts there is a movable wire bracket h, at both ends of which small brackets ζ are bent to act as hold-downs. These hold-down devices i are pressed down onto the board by the double, that is to say on two sides, wound spiral spring s , whereby the pressing of the photographic plate or the negative to be copied is effected.
Zwischen den Bügeln h und i ist noch eine Oese \ angebogen, welche gleichzeitig als Scharnier dient. Durch Oese \ und Spiralfeder s geht ein an beiden Enden abgebogener Drahthaken x, welcher Oese und Spiralfeder mit dem Brett verbindet. H between the temples and i is still an eyelet \ attached bow, which simultaneously serves as a hinge. By Oese \ and spiral spring S is bent at both ends of x a wire hook, which connects eyelet and coil spring with the board.
Zum leichteren Oeffnen der Niederhalter i ist in der Mitte, unter jedem grofsen Drahtbügel h, noch ein Griff k angeordnet. Soll das photographische Negativ auf das Brett gelegt werden, so hebt ein leiser Druck auf Bügel h und Griff k die Niederhalter i vom Brett ab, und nach Auflegen der Glasplatte (bezw. des Negativs) wird dieselbe durch Loslassen der Bügel h und der Griffe k auf das Brett festgeklemmt. To make it easier to open the hold-down device i , a handle k is arranged in the middle under each large wire bracket h. If the photographic negative is to be placed on the board, light pressure on the bracket h and handle k lifts the hold- down device i from the board, and after the glass plate (or the negative) has been placed on the board, it is released by releasing the bracket h and the handles k clamped onto the board.
Um ein Zerbrechen der Glasplatten zu verhüten, sind die Bretter A und B mit Filzplatten belegt. In order to prevent the glass plates from breaking, boards A and B are covered with felt plates.
