Description

KAISERLICHES A IMPERIAL A

PATENTAMT.PATENT OFFICE.

Den Gegenstand vorliegender Erfindung bildet ein Schlüssel zum Befestigen bezw. Lösen von Schraubenmuttern bezw. -Bolzen, welcher ohne Umstecken eine beliebige Arbeitsbewegung gestattet. The subject of the present invention forms a key for fastening BEZW. To solve Screw nuts respectively. -Bolt, which allows any working movement without repositioning.

Zu diesem Zwecke ist in einem Schraubenschlüssel α nach Art der bekannten Bohrknarren ein Sperrrad b eingesetzt, dessen Oeffnung gleichzeitig für zwei Mutterngröfsen pafst. In die Zahnung des Rades b greifen auf jeder Seite je eine durch Feder angedrückte Klinke c ein, welche ein Drehen des Sperrrades nach je einer Seite verhindern.For this purpose, a ratchet wheel b is used in a wrench α in the manner of the known ratchets, the opening of which fits two nut sizes at the same time. A spring-pressed pawl c engages in the teeth of the wheel b on each side and prevents the ratchet wheel from turning to one side.

Um eine Bewegung des Schlüssels nach zwei Seiten zu ermöglichen, ist ein am Griff α vorgesehener Bügel d derart angeordnet, dafs, wie aus beiliegender Zeichnung ersichtlich ist, immer eine der Klinken c ausgelöst ist, während die andere in das Sperrrad eingreift.To enable movement of the key in two directions, a bracket d provided on the handle α is arranged in such a way that, as can be seen from the accompanying drawing, one of the pawls c is always triggered while the other engages the ratchet wheel.

Durch die entsprechende Stellung des Bügels d kann somit ohne Umstecken des Schlüssels eine Bewegung nach beiden Seiten hin ermöglicht werden.Through the appropriate position of the bracket d , a movement to both sides can thus be made possible without changing the key.
