Am Wagenrahmen 1 ist nahe hinter dem Stoßbalken parallel zur Wagenachse die Welle 11 gelagert, an der der zweckmäßig aus einem mit Drahtgeflecht überspannten Rohrrahmen gebildete Taster 12 um seine obere Kante drehbar aufgehängt ist. Mit diesem Rahmen ist das über die Welle hinaufgreifende Segment 10 mit im Kreisbogen um die Welle 11 angeordneten Bohrungen 13 (Fig. 9 und 10) fest verbunden. Am Lager für die Welle 11 sitzt der Arm 14, an dessen oberem Ende der unter Federwirkung stehende, zum Einschnappen in eine in seine Längsrichtung gestellte Bohrung 13 des Segmentes 10 und so' zum Arretieren des Segmentes 10 und damit auch des Tasters 12 bestimmte Arretierstift 9 angeordnet ist.i Ebenfalls mit dem Rahmen des Tasters 12 fest verbunden ist ein Arm, der den Anschlagzapfen 6 trägt. Dieser muß also eine Drehbewegung des Tasters mitmachen. Parallel zur Wagenachse ist hinter dieser am Wagenrahmen 1 die Welle 8 drehbar gelagert, auf welcher der Mitnehmer 5 und der an dem Zapfen 6 anschlagende Arretierhebel 7 festsitzen. Rechtwinklig zur Welle. 11. also parallel zur Längsachse des Wagens, ist die Stange 2 angeordnet, die in der Längsrichtung verschiebbar, aber nicht um ihre Achse drehbar ist und unter Wirkung der um das hintere Stangenende angeordneten Feder 3 steht. Auf dieser Stange 2 sitzt in der Nähe des vorderen Endes derselben der in den Mitnehmer 5 greifende Zapfen 4 fest. In der Nähe des hinteren Endes der Stange 2 sitzt auf letzterer ein Ring fest, der mit dem nach unten in die Öse des Klauenstückes 18 greifenden Stift 17 und der nach oben "um den Bolzen 16 greifenden, das Drehen der Stange 2 verhütenden Gabel 15 ausgestattet ist. Am Lager für das hintere Ende der Stange 2 sitzt die Hülse 21 fest, in der die beiden Klauenstücke 18 und 19 (Fig. 2 bis 8) um den durchgehenden Bolzen 25 sowie die an das Klauenstück 19 anschlagende Feder 20 angeordnet sind. Das Klauenstück 18 ist mit einem Ösenlappen versehen, der mit der Hülse 21 und dem Zapfen 17 in Eingriff steht. Außerdem besitzt das Klauenstück 18 drei gegen das Klauenstück 19 gerichtete Klauen, und ist um den Bolzen 25 drehbar, aber nicht in dessen Längsrichtung verschiebbar angeordnet. Das Klauenstück 19 dagegen ist in der Längsrichtung des Bolzens 25 auf demselben verschiebbar, aber nicht umOn the carriage frame 1, near behind the shock beam, the shaft 11 is parallel to the carriage axis stored, on which the expediently made of a tubular frame spanned with wire mesh formed button 12 is suspended rotatably about its upper edge. With this framework is the segment 10 reaching up over the shaft in a circular arc around the shaft 11 arranged holes 13 (Fig. 9 and 10) firmly connected. At the bearing for the shaft 11 sits the arm 14, at the upper end of which is under the action of a spring, to snap into place in a set in its longitudinal direction bore 13 of the segment 10 and so 'for Locking the segment 10 and thus also the button 12 certain locking pin 9 is arranged ist.i Also firmly connected to the frame of the button 12 is an arm that the stop pin 6 carries. This must therefore take part in a rotary movement of the button. The shaft 8 is rotatably mounted behind this on the carriage frame 1 parallel to the carriage axis, on which the driver 5 and the locking lever 7 abutting against the pin 6 are stuck. At right angles to the shaft. 11. So parallel to the longitudinal axis of the car is the Rod 2 arranged, which is displaceable in the longitudinal direction, but not rotatable about its axis and is under the action of the spring 3 arranged around the rear end of the rod. on this rod 2 sits near the front end of the same in the driver 5 gripping pin 4 firmly. Near the rear end of the rod 2 sits on the latter a ring fixed with the pin reaching down into the eye of the claw piece 18 17 and the up "around the bolt 16 gripping fork 15 preventing the rod 2 from rotating. In stock for the rear end of the rod 2, the sleeve 21, in which the two claw pieces 18 and 19 (FIGS. 2 to 8) around the through bolt 25 as well as those on the claw piece 19 abutment spring 20 are arranged. The claw piece 18 is provided with an eyelet flap, which is in engagement with the sleeve 21 and the pin 17. Also owns the Claw piece 18 has three claws directed against the claw piece 19, and is around the bolt 25 rotatable, but not arranged to be displaceable in its longitudinal direction. The claw piece 19 on the other hand, the bolt 25 is displaceable on the same in the longitudinal direction, but not around

the bolt is rotatably arranged. The two-armed, ■ by means of bolts 23 articulated with the arm reaching backwards from the catch element 26 Pull rod 24 is connected to the claw piece 19. Two slots in the wall . of the sleeve 21 enable this connection as well as the displacement of the screw bolts 22 with the claw piece 19. Between the bottom of the sleeve 21 and the claw piece 19 sits the spring 20, which is used to push up the claw piece 19 in the appropriate position of the claw piece 18 is determined. The sleeve 21 with the two claw pieces 18 and 19 and the spring 20 thus form a top and bottom closed by the bolt 25 Tension spring pot, in which when the claws of the pieces 18 and 19 are placed one on top of the other, the Spring 20 is so tensioned that after rotation of the piece 18 from the indicated above Position the spring 20 lifts the piece 19 with the hanging frame, until the two pieces 18 and 19 are fully engaged with them. The catch organ 26 is formed by a tubular frame spanned by a wire mesh, the rotatably mounted on the carriage frame parallel to the carriage axis about the shaft 25, on his front end flattened and close to last

30. rem with on a decapitated crossbar is equipped with rotatable rollers. An arm stuck to this frame reaches out its rear cross tube to the rear and is articulated at its end by means of bolts 23 connected to the double arm pull rod 24. When the spring 20 is tensioned, there is a result this arrangement the catching organ in the rest position, on the other hand it is by relaxing the The spring is forced into the working position.

The effect of this device is now as follows:

If a foreign object lying on the road hits the button 12, only that is Overcome lock 10-9 in order to rotate the easily rotatable net frame backwards. During this rotation, the pin 6 is turned upwards, the locking lever 7 is released, and the shaft 8 with locking lever 7 and driver 5 is only supported by the pin 4 provided rod 2 commands. Now the effect of the spring 3 comes into play. The rod 2 moves as a result of the same in the opposite direction to the direction of travel and takes in this movement. the ring with the pin 17 with. The in the eyelet of the claw piece 18 engaging pin 17 the latter so that the up to then one another stationary end faces of the claws of 18 and 19 can be adjusted against each other. Now the previously tensioned spring 20 comes into action. She relaxes and slides the piece 19 upwards and supports the rotation as a result of the claw shape of the piece 18 until the claws are fully engaged. The claw piece pulls 19 by means of the double-armed tie rod 24, the end of the frame arm at 23 high, see above that the net frame lowers with its front end, so the catch frame in the working position steps and picks up the obstacle.

If the device is to be brought back into the rest position, then first must be done Tensioning the spring 20 of the catch frame 26 is lifted at its front end and then the rod 2 can be pushed forward to lock the tensioned spring. Then the button 12 to secure the advanced position of rod 2 in brought the position shown in FIG.

With this device, for example, as illustrated by FIG. 1, a Sand spreader can be connected to it at the moment in which the safety gear comes into action, the sliding of the wheels on the rails is avoided as much as possible. In this embodiment, the angle lever 28 mounted at 27 is articulated on the one hand with the pull rod 24 of the safety gear, on the other hand with the slide of the sand pipe 29 connected so that simultaneously with the setting of the safety gear in the working position the functioning of the. Sand spreader can be achieved. Likewise, the facility can also be connected to the brake.
