Description

Schraubenklemme. Die Erfindung richtet sich auf eine Schraubenklemme zum Verhindern des Wanderns von Eisenbahnschienen unter Verwendung eines U-förmigen Stemmstücks, dessen einer Schenkel zur Anlage an Holzschwellen, dessen anderer Schenkel zur Anlage an Eisenschwellen bestimmt und eingerichtet ist, wobei Klemmbacken den Schienenfuß und das Stemmstück durch mehrfache Verspannung festverbinden. DieEigenart derneuenKlemme kennzeichnet sich dadurch, daß der Steg des U-förmigen Stemmstücks eine an den Längsseiten vom Steg abgetrennte Ausbiegung besitzt, die beim Anziehen der Schraube durch die Klemmbacken federnd gegen den Schraubenschaft gepreßt wird. Das Stemmstück wird auf diese Art mit dem Schienenfuß unmittelbar sicher und doch federnd verspannt, ohne daß das feste Einklemmen der Enden des Stemmstücks in den Maulöffnungen der Klemmbacken beeinträchtigt wird.Screw clamp. The invention is directed to a screw clamp for preventing railroad tracks from wandering using a U-shaped Stemmstücks, whose one leg to rest on wooden sleepers, the other leg is intended and set up to rest on iron sleepers, with the clamping jaws Firmly connect the rail foot and the chisel by multiple bracing. The peculiarity the new clamp is characterized in that the web of the U-shaped caulking piece has a bend separated from the web on the long sides, which when tightened the screw is pressed resiliently against the screw shaft by the clamping jaws. In this way, the caulking piece is immediately secure and yet with the rail foot resiliently tensioned without the firm clamping of the ends of the caulking piece in the Jaw openings of the jaws is impaired.

In der Zeichnung ist die Erfindung durch einen Längsschnitt, Abb. z, und durch eine Seitenansicht der Klemme, Abb. z, beispielsweise veranschaulicht.In the drawing, the invention is represented by a longitudinal section, Fig. z, and illustrated by a side view of the clamp, Fig. z, for example.

Zur Befestigung der Klemme an der Schiene a dienen die Klemmbacken b, die durch die Schraube b' zusammengezogen werden. Hierbei legt sich die nach Einschneiden des Steges des Stemmstücks c durchgebogene Auspressung c' federnd von unten her gegen eine Fläche des Schraubenschaftes und wird beim Zusammenziehen der Backen b durch die doppelte Keilanpressung oberhalb des Schienenfußes einerseits, durch das keilförmige untere Klemmbackenmaul anderseits dagegen gepreßt, wodurch die obere Fläche der Schraube b' fest mit dem Schienenfuß verbunden wird.The clamping jaws b, which are pulled together by the screw b ', are used to fasten the clamp to the rail a. Here, after cutting into the web of the caulking piece c, the press-out c 'resiliently lies against a surface of the screw shaft from below and is pressed against a surface of the screw shaft when the jaws b are pulled together by the double wedge pressure above the rail foot on the one hand, and on the other hand by the wedge-shaped lower jaw mouth, whereby the upper surface of the screw b 'is firmly connected to the rail foot.

Die nachgiebige Auspressung c' des Stemmstücks ergibt eine günstige Federwirkung. Im übrigen tritt eine vierfache Verspannung auf. Die Klemme besteht aus Walzquerschnitten und läßt sich einfach herstellen. Der Steg des Stemmstücks wird beiderseits von dem klauenförmigen Maul der Backen b sicher geführt.The flexible compression c 'of the caulking piece results in a favorable one Spring action. Otherwise there is a four-fold tension. The clamp exists from rolled cross-sections and is easy to manufacture. The web of the caulking piece is safely guided on both sides by the claw-shaped mouth of the jaws b.
