Eisenbetonschwelle.
Die Erfindung betrifft eine Eisenbetonschwelle, bei welcher das Festhalten der Schienen durch Schraubenbolzen erfolgt, die Längsschlitze der Schwelle durchsetzen und besteht darin, dass die Schlitze nach oben zu sich erweitern. Diese Ausgestaltung hat den Vorteil, dassdieBolzenauchbeiunebenerOberflächederSchwellefestgestelltwerdenkönnen, wobei sowohl die Bolzenköpfe als auch die Schraubenmuttern auf ihrer Unterlage vollkommen aufsit/on, wodurch übermässig hohe Flächenpressungen vermieden werden und die BefestIgung der Schienen auf den Schwellen selbst dauerhafter und widerstands- fähiger wird.
Auf der Zeichnung ist eine Eisenbetonschwelle gemäss der Erfindung in einem Ausführungsbeispiel dargestellt, und zwar zeigt Fig. 1 zwei Schwellen in Verbindung mit der Schiene im Schaubild und Fig. 2 einen Querschnitt der Schwelle an der Stelle der Schlitze.
Die Schwelle a ist in bekannter Weise mit einer Längsarmierung bund Querarmierung c versehen und besitzt an den Enden durchgehende Längsschlitze d, die der Erfindung Gemäss nach oben erweitett sind. Die Schlitze dienen zur Aufnahme der Be-

Reinforced concrete sleeper.
The invention relates to a reinforced concrete sleeper in which the rails are held in place by screw bolts which penetrate the longitudinal slots of the sleeper and consists in the slots expanding towards the top. This configuration has the advantage that the bolts can also be fixed on an uneven surface of the sleeper, with both the bolt heads and the screw nuts completely on their base, which avoids excessively high surface pressures and the fastening of the rails on the sleepers themselves becomes more permanent and resistant.
In the drawing, a reinforced concrete sleeper according to the invention is shown in one embodiment, namely FIG. 1 shows two sleepers in connection with the rail in the diagram and FIG. 2 shows a cross section of the sleeper at the location of the slots.
The threshold a is provided in a known manner with a longitudinal reinforcement and transverse reinforcement c and has continuous longitudinal slots d at the ends, which according to the invention are widened upwards. The slots are used to accommodate the

The hotnkopf rests on a resilient rail e, which in a known manner prevents the fastening bolt from loosening automatically.
