Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Klemm- und Feststellvorrichtung soll dazu dienen, Werkzeuge oder Arbeitsstücke während der Arbeit bezw. während der Bearbeitung zu halten, und zwar sollen die Theile in der Schlufslage sich selbsttätig erhalten, sowie der zur Bewegung derselben dienende Handhebel von der einen auf die andere Seite herumgelegt ist.The present clamping and locking device is intended to serve tools or workpieces during work or to keep while editing, namely the Parts in the final position maintain themselves automatically, as well as those for moving them serving hand lever is laid around from one side to the other.
In Fig. ι sind die Theile in der Schlufslage und in Fig. 2 in der Offenlage dargestellt. Es bezeichnen pp' einarmige Prefshebel, welche bei q q' auf einer gemeinsamen Unterplatte m drehbar gelagert sind. Dieselben sind an der inneren Seite etwas herausgebaucht und tragen an diesen Stellen Ansätze ο ο\ zwischen denen, die betreffenden Werkzeuge oder Arbeitsstücke festgehalten werden, sobald die Prefshebel gegen einander bewegt sind. Die freien Enden dieser Hebel sind durch Glieder r r1 mit einem zweiarmigen Handhebel t verbunden, welcher bei i' ebenfalls auf der Unterplatte m gelagert ist.In Fig. 1 the parts are shown in the closing position and in Fig. 2 in the open position. It denotes pp ' one-armed preflever, which at qq' are rotatably mounted on a common lower plate m. The same bulges out a little on the inner side and at these points have approaches ο ο \ between those, the tools or workpieces in question are held as soon as the Prefs levers are moved against each other. The free ends of these levers are connected by links rr 1 to a two-armed hand lever t , which is also mounted on the lower plate m at i '.
Es sind nun die Glieder derart gestaltet, und es ist die Verbindung derart bewirkt, dafs die Dreh- oder Verbindungspunkte der Theile ρ r t r1 p1 bei Schlufslage (s. Fig. 1) sich in einer geraden Linie gewissermafsen in der Todtpunktstellung befinden und sich von selbst nicht mehr aus dieser Stellung entfernen können. Es kann so durch geringe Kraftaufwendung eine grofse Kraftwirkung erzielt werden, da sowohl bei dem Handhebel t als auch bei den Prefshebeln ρ ρ' stets ein grofser Hebelarm zur Wirkung kommt.The links are now designed in such a way, and the connection is effected in such a way that the points of rotation or connection of the parts ρ rtr 1 p 1 in the closing position (see Fig. 1) are in a straight line, so to speak, in the dead point position can no longer remove themselves from this position. A great force effect can thus be achieved by applying little force, since both the hand lever t and the pressure levers ρ ρ 'always have a large lever arm.
