Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Der Schraubenschlüssel ist zum Anziehen von Muttern verschiedener Gröfsen anzuwenden.The wrench is used to tighten nuts of various sizes.

Derselbe besteht aus zwei Theilen, dem Schlüsselhandgriff α und dem Schlüsselmaul b. Handgriff und Schlüsselmaul bilden zusammen ein Scharnier, so dafs sich das Schlüsselmaul 90° um den Scharnierstift c frei bewegen kann.It consists of two parts, the key handle α and the key mouth b. The handle and the keyhole together form a hinge so that the keyhole can move freely through 90 ° around the hinge pin c.

Der über den Scharnierdrehstift hinaus verlängerte Theil des Handgriffes ist mit prismatischen Erhöhungen und Vertiefungen versehen, durch welche eine bestimmte, den vorkommenden Muttergröfsen entsprechende, zahnartige Eintheilung e geschaffen ist.The extended about the hinge pivot pin addition, part of the handle is provided with prismatic elevations and depressions, by which a specific, corresponding to the occurring Muttergröfsen, tooth-like division e is provided.

Bei Benutzung des Schlüssels wird die anzuziehende Mutter im Winkel α von den beiden Maulflächen f und g und sodann von den ■ beiden Flächen derjenigen zahnartigen Vertiefung des verlängerten Handgriffes erfafst, welche entsprechend der Gröfse der Mutter vorgesehen ist.When using the wrench, the nut to be tightened is gripped at the angle α by the two mouth surfaces f and g and then by the two surfaces of that tooth-like recess of the extended handle, which is provided according to the size of the nut.

Der Schraubenschlüssel erfafst daher jede in der Eintheilung des verlängerten Handgriffes vorgesehene Mutter. Letzteres erfolgt deshalb, weil der Raum zwischen dem Maulschenkel d und der zahnartigen Eintheilung des verlängerten Handgriffes sich zu verkleinern bestrebt ist. . .The wrench therefore grasps every nut provided in the division of the extended handle. The latter takes place because the space between the jaw leg d and the tooth-like division of the extended handle strives to be reduced. . .
