KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der neue Schraubenschlüssel besitzt zwei feste Backen, zwischen . welchen der Länge nach verschiebbare Füllstücke "zum Einstellen des Schlüssels für verschiedene Muttergröfsen angeordnet sind.The new wrench has two fixed jaws, between. which of the length after sliding filler pieces "for setting the key for different nut sizes are arranged.
Durch die in der Längsrichtung verschiebbaren Füllstücke unterscheidet sich dieser Schlüssel von dem durch die Patentschrift Nr. 30459 bekannt gewordenen Schlüssel, bei welchem die Füllstücke um Bolzen aufklappbar angeordnet sind.This differs due to the filler pieces that can be moved in the longitudinal direction Key from the key made known by patent specification No. 30459 which the filler pieces are arranged to be hinged around bolts.
In der beiliegenden Zeichnung ist Fig. 1 die Seitenansicht, Fig. "2 die Endansicht eines derartigen Schraubenschlüssels.In the accompanying drawing, Fig. 1 is the Side view, Fig. "2 is the end view of such a wrench.
Der Schlüssel wird aus Stahlblech gestanzt und besitzt die in Fig. 1 ersichtliche U-Form. Die Enden α α1 der beiden Schenkel A A1 bilden die Backen des Schlüssels und sind durch angenietete Laschen B B1 gegen einander verspannt. Der hierdurch bedingte Abstand der Backen α α1 entspricht der gröfsten Mutter, welche noch mit dem Schlüssel gefafst werden soll. Um die Schlüsselweite verringern zu können, sind zwischen den Schenkeln A A x und den Querverbindungen B B1 der Länge nach verschiebbare, über einander liegende Gleitschienen c1 c2 c3 c* c5 c6 c7 c8 angeordnet, von welchen je nach Bedarf eine oder mehrere derart vorgeschoben werden können, dafs der Raum zwischen den Backen α α1 verringert wird.The key is punched from sheet steel and has the U-shape shown in FIG. 1. The ends α α 1 of the two legs AA 1 form the jaws of the key and are braced against each other by riveted tabs BB 1. The resulting distance between the jaws α α 1 corresponds to the largest nut that is still to be grasped with the key. In order to be able to reduce the width across flats, sliding rails c 1 c 2 c 3 c * c 5 c 6 c 7 c 8 are arranged between the legs AA x and the cross connections BB 1 longitudinally displaceable, one above the other, of which as required one or more can be advanced in such a way that the space between the jaws α α 1 is reduced.
Diese Schienen wirken demnach als Füllstücke, welche sich zwischen dem einen Backen des Schlüssels und der Seitenfläche der Mutter befinden. Bei der Ausführung des Schlüssels werden vorteilhaft die beiden Backen von einander verschieden gemacht, wie dies die Zeichnung veranschaulicht. Die erste Schiene c1 liegt unmittelbar an dem Backen a an, während die letzte Schiene c8 in verschobener Lage von dem Backen al einen der kleinsten Mutter entsprechenden Abstand besitzt. Sind mehrere Gleitschienen vor die wirksame Fläche des. Backens α geschoben worden, um die Weite des Schlüssels der Gröfse der Mutter anzupassen, so kann diese letztere fest zwischen den Schienen und dem anderen Backen ergriffen werden, während die übrigen Gleitschienen zurückgeschoben bleiben (Fig. 1).These rails therefore act as filler pieces, which are located between one jaw of the key and the side surface of the nut. When executing the key, the two jaws are advantageously made different from one another, as the drawing illustrates. The first rail c 1 rests directly on the jaw a , while the last rail c 8 in a shifted position from the jaw a l has a distance corresponding to the smallest nut. If several slide rails have been pushed in front of the effective surface of the jaw α in order to adapt the width of the wrench to the size of the nut, the latter can be firmly gripped between the rails and the other jaw, while the remaining slide rails remain pushed back (Fig. 1 ).
Die Gleitschienen c1 bis c8 sind mit seitlich vorspringenden Lappen c versehen, welche das Verschieben der Gleitschienen erleichtern und durch Anstofsen an die Querverbindungen BB1 die Bewegung der Schienen begrenzen und das Herausfallen derselben verhindern.The slide rails c 1 to c 8 are provided with laterally protruding tabs c , which make it easier to move the slide rails and limit the movement of the rails by means of attachments to the cross connections BB 1 and prevent them from falling out.
Die Enden C1 der Schienen sind etwas abgerundet, um das Ansetzen des Schlüssels an die Mutter zu erleichtern.The ends C 1 of the rails are slightly rounded to make it easier to attach the wrench to the nut.
