HERMANN BRANDES in HAMBURG. Arbeitsmesser.HERMANN BRANDES in HAMBURG. Working knife.
Auf der Zeichnung sind zwei Arten von Arbeitsmessern dargestellt, deren Schalen d d' durch Scharniere verbunden sind. Bei der in den Fig. 1 bis 3 gezeichneten Construction geht durch die unteren Enden beider Schalenhälften ein gemeinschaftlicher Drehstift e, während die Schalen oben durch einen mittelst der Feder/ arretirten Ring g zusammengehalten werden. In der Construction Fig. 4 und 5 sind beide Schalenhälften durch Scharniere e' e' vereinigt; das freiwillige Aufklappen wird auch hier durch den Ring g und die Feder/ verhindert.The drawing shows two types of working knives, the shells d d 'of which are connected by hinges. In the construction shown in FIGS. 1 to 3, a common pivot pin e passes through the lower ends of both shell halves, while the shells are held together at the top by a ring g locked by means of the spring. In the construction of FIGS. 4 and 5, both shell halves are united by hinges e 'e'; voluntary opening is also prevented here by the ring g and the spring /.
In einer der Schalen (oder auch in beiden) bezw. in einem darin befestigten Futter befinden sich eine Anzahl Löcher, welche zur Aufnahme des an der Klinge b angebrachten Ansatzes a dienen. Entsprechend der Abnutzung des oberen Endes der Klinge hängt man dieselbe in das entsprechende Loch der Schale ein und befestigt sie dadurch in der Richtung des beim Arbeiten gegen die Klinge ausgeübten Zuges, während die geschlossenen Schalen ein Seitwärtsausbiegen verhindern.In one of the bowls (or in both) respectively. in a chuck mounted therein are a number of holes, which serve for receiving the blade on the b attached approach a. Depending on the wear and tear of the upper end of the blade, it is hung in the corresponding hole in the shell and thereby fastened in the direction of the pull exerted on the blade when working, while the closed shells prevent it from bending sideways.
