KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Der vorliegende Schraubenschlüssel dient zum Anziehen oder Lösen schwer zugänglicher und starker Schraubenbolzen oder Muttern unter gleichzeitiger Anzeige der hierzu erforderlichen Kraft, damit ein Überschrauben oder Abreißen der Bolzen verhindert . wird. Der Schlüssel soll hauptsächlich zum Anziehen der zum Befestigen von Panzerplatten auf Kriegsschiffen zu gebrauchenden ίο Schraubenbolzen Verwendung finden, wobei die Schiffsspanten als Widerlager für den Schlüssel dienen.This wrench is used to tighten or loosen hard-to-reach areas and strong screw bolts or nuts with simultaneous display of the force required for this, thus an over-screwing or tearing off of the bolts is prevented. will. The key is mainly intended to Tightening of those used to attach armor plates on warships ίο Find bolts use, with the ship bulkheads as an abutment for the Serving keys.

Er besteht aus dem Gehäuse f, einem Zahnrad c, welches durch die Schneckenwelle d in Bewegung gesetzt wird, und dem auf die Enden der Schneckenwelle passenden Kraftanzeiger. In dem Gehäuse laufen Schneckenzahnrad und Schneckenwelle. · Das Zahnrad . hat in der Mitte eine Öffnung g zur Aufnähme der Mutter. Um verschiedene Größen von Muttern zu fassen, können in die Öffnung auswechselbare Fassungen eingesetzt werden. Auf dem Vierkant e der Schneckenwelle sitzt eine Knarre oder ein Schlüssel, das an- · dere Ende der Welle wird mit dem Kraftanzeiger als Widerlager ausgebildet. Hierzu ist ein Zwischenglied 3 eingefügt.It consists of the housing f, a gear c, which is set in motion by the worm shaft d, and the force indicator that fits on the ends of the worm shaft. The worm gear and worm shaft run in the housing. · The gear. has an opening g in the middle for receiving the mother. Interchangeable sockets can be inserted into the opening to accommodate different sizes of nuts. A ratchet or a wrench sits on the square e of the worm shaft, the other end of the shaft is designed as an abutment with the force indicator. An intermediate member 3 is inserted for this purpose.

.Kraftanzeiger in Verbindung mit Schraubenschlüsseln zum Messen der aufgewendeten < Kräfte sind an sich bekannt.. Force indicator in connection with wrenches for measuring the forces applied are known per se.
