ALBERT AMUNDSON in HUDIKSVALL (Schweden). Briefcopirapparat.ALBERT AMUNDSON in HUDIKSVALL (Sweden). Letter copier.
Patentirt im Deutschen Reiche vom 30. August 1878 ab:Patented in the German Empire on August 30, 1878:
Dieser Briefcopirapparat soll die bisher gewöhnliche Schraubenpresse beim Briefcopiren ersetzen. Derselbe besteht aus folgenden Theilen:This letter copier is supposed to be the usual screw press for letter copying substitute. It consists of the following parts:
1. dem Gestell b, Fig. 1, aus Holz, Glas, Porcellan oder Metall nebst den Handgriffen b';1. the frame b, Fig. 1, made of wood, glass, porcelain or metal together with the handles b ' ;
2. der Zwischenplatte i, Fig. 1, ia, 2, aus irgend elastischem Metall;2. the intermediate plate i, Fig. 1, ia, 2, from any elastic metal;
3. der besonders präparirten Druckfläche a, Fig. ι, ι a, 2, welche aus Carton, Leder, Holz, Tuch oder Kautschuk gemacht wird.3. the specially prepared printing surface a, Fig. Ι, ι a, 2, which is made of cardboard, leather, wood, cloth or rubber.
4. dem metallenen Kasten e, in welchem der Kautschukschwamm d durch die Kautschukbänder d' befestigt wird, Fig. 3. Der eigentliche Briefcopirapparat kann jedoch auch ohne diesen Schwamm angewendet werden.4 is attached to the metal case e, wherein the rubber sponge d d by the rubber bands', Fig. 3. The actual Briefcopirapparat but can be practiced without these sponge.
Bei diesem Apparate kommt nur ein so geringer Theil auf einmal in Berührung mit dem Copirblatt, dafs es sehr leicht ist, durch Handkraft denselben Druck, wie mit der Presse, nach und nach auf das ganze Copirblatt zu übertragen. In this apparatus only so small a portion comes into contact with it at one time Copy sheet that it is very easy to apply the same pressure by hand force as with the press and afterwards to be transferred to the whole copy sheet.
Beim Gebrauch wird die Druckfläche a des Apparates über den mäfsig nassen Kautschukschwamm gerollt und dadurch angefeuchtet; dieses kann aber auch mittelst eines gewöhnlichen Copirpinsels geschehen. Unter mäfsigem Druck gegen die Handgriffe b' wird die Presse über das Copirblatt geführt. Man kann aber auch dieses Blatt wie gewöhnlich direct anfeuchten und danach den Apparat darüber hinwegführen. In diesem Falle wird man sich vorzugsweise der Construction, Fig. 1 a, mit Kautschukumhüllung bedienen. Fig. 4 zeigt eine endlose Druckfläche, welche durch die Feder des Metallgestelles gespannt wird. Fig. 5 zeigt eine ähnliche Druckfläche, welche durch das Anschrauben der Handgriffe b' gegen die Kautschukplatten/ gespannt wird. In der Construction, Fig. 6, wird die Druckfläche durch die Kautschukringe/' gespannt. Die Fig. 7, 8 und 9 zeigen, wie eine aufgeschnittene Drückfläche durch die Spiralfeder f in das Gestell gespannt wird.In use, the pressure surface a of the device is rolled over the moderately wet rubber sponge and thereby moistened; but this can also be done by means of an ordinary copir brush. The press is guided over the copy sheet with moderate pressure against the handles b '. But one can also moisten this sheet directly, as usual, and then move the apparatus over it. In this case one will preferably use the construction, Fig. 1 a, with a rubber cover. Fig. 4 shows an endless pressure surface which is tensioned by the spring of the metal frame. Fig. 5 shows a similar pressure surface which is tensioned by screwing the handles b ' against the rubber plates /. In the construction, Fig. 6, the pressure surface is tensioned by the rubber rings / '. 7, 8 and 9 show how a cut-open pressure surface is tensioned into the frame by the spiral spring f.
