Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Den Gegenstand der vorliegenden Erfindung bildet ein Gelenk für zweiarmige Werkzeuge, wie Scheeren, Zangen u. dgl., durch welches erzielt wird, dafs der bei der Arbeit rechtwinklig auf den Verbindungsbolzen ausgeübte Druck nicht von diesen aufgenommen wird. Hierdurch wird die Arbeit erheblich erleichtert und der Bolzen nicht abgenutzt, was bisher gewöhnlich sehr schnell der Fall war.The subject of the present invention is a joint for two-armed tools, like scissors, pliers, and the like, by means of which it is achieved that the work is at right angles pressure exerted on the connecting bolt is not absorbed by the latter. This makes the work much easier and the bolt is not worn, which has usually been very quick in the past.

Das Wesen der Erfindung beruht darin, dafs die beiden Arme des Werkzeuges an ihrer Verbindungsstelle mit einer oder mehreren in einander liegenden ringförmigen Aussparungen versehen sind, welche den Verbindungsbolzen oder dergl. umgeben. Diese Aussparung wird durch einen Ring ausgefüllt, welcher den bei der Arbeit rechtwinklig zur Drehachse der Arme ausgeübten Druck aufnimmt, so dafs der Verbindungsbolzen lediglich als solcher dient und sonst in keiner Weise belastet wird.The essence of the invention resides in the fact that the two arms of the tool are attached to it Connection point with one or more annular recesses lying one inside the other Are provided which surround the connecting bolt or the like. This recess will filled with a ring, which is at right angles to the axis of rotation when working Arms exerted pressure, so that the connecting bolt only serves as such and is not burdened in any other way.

Der Erfindungsgegenstand ist auf der Zeichnung an einer Blechscheere dargestellt, und zwar zeigt:The subject of the invention is shown in the drawing on sheet metal shears, and although shows:

Fig. ι eine Ansicht der geöffneten und Fig. 2 einen Schnitt durch A-B der Fig. 1 der geschlossenen Scheere.Fig. Ι a view of the open and FIG. 2 a section through AB of FIG. 1 of the closed scissors.

Die Arme oder Schenkel b c der Scheere sind in bekannter Weise durch einen Bolzen a gelenkig mit einander verbunden. Diesen Bolzen umschliefsend und in einer ringförmigen Aussparung an der Innenseite beider Schenkel gelagert, ist ein Ring d angeordnet, welcher den bei der Arbeit senkrecht zu der Verbindungsachse α ausgeübten Druck aufnimmt. Für Werkzeuge, mit welchen schwere Arbeiten verrichtet werden sollen, können mehrere solcher Ringe verwendet werden.The arms or legs bc of the scissors are articulated to one another in a known manner by a bolt a. Surrounding this bolt and mounted in an annular recess on the inside of both legs, a ring d is arranged which absorbs the pressure exerted perpendicular to the connection axis α during work. Several such rings can be used for tools with which heavy work is to be carried out.
