The other end of the clamping spindle, which is provided with an opposing thread, engages in one second * 'mother, which in turn is between the legs of a flattened U-piece or shackle is used pivotably, this shackle the coupling piece for engaging in the coupling hook of the second rail vehicle forms, and the tensioning of the coupling with one in the middle of the The clamping spindle attached and the hand lever protruding vertically from it can be carried out.

It is also known that other rail vehicles are provided with an automatic coupling are. Such known couplings consist of coupling cords, which with the help of in the direction of the vehicle's longitudinal axis acting damping springs are mounted and the complementary outer and have inner profiles that allow them to latch into each other through simple axial thrusts when approaching of the vehicles to be coupled «It is also known that the European railways strive to to soon extend this automatic coupling to all rail vehicles in traffic, from which the following difficult problem arises: in practice, namely, the spread of the automatic coupling on all rail vehicles will likely take several years

must be used side by side. The simultaneous presence of rail vehicles. Of which some with an automatic claw coupling, the others with the usual screw coupling requires the use of transition devices, which allow vehicles of both types to be coupled together.

A device of this type has already been proposed (cf. in particular German patent application S 94 544 II / 20e, based on French patent application 956 664 of December 10, 1963) in which the usual clamping spindle with one piece

This Piece can be brought into a position suitable for coupling with an automatic coupling or it can be swiveled away so that one vehicle equipped with it can be coupled to another Vehicle, which has the usual screw coupling, to enable · With this device the piece, which serves as a coupling head and interacts with the coupling claws L of an automatic coupling, carried by a rod attached to its other end is connected to the member carrying the clamping spindle, this member being fastened to the coupling hook. which is equipped with the usual screw coupling

is, the auxiliary coupling head is out of action by simply letting it hang down at the end of its pole, and the coupling takes place with the help of the tensioning spindle of the second wagon, whose shackles are in the hooks of the first Wagons is hooked. If, on the other hand, both cars are equipped with a device for mixed coupling as described above, coupling can take place can only be done by swiveling the auxiliary coupling head upwards on the wagon whose screw coupling is to be used · This upward swiveling is certainly possible, but cannot be carried out without it leads to difficulties in terms of operation and safety.

Di-e — device for mixed coupling according to the invention solves this problem in a very simple way

Manner, namely by the fact that the connecting element

Thanks to this arrangement and device, when using the screw coupling of the invention Device for mixed coupling, the transition coupling piece simply with his lever out of the

the load-bearing link is provided for this purpose on the / clamping spindle / The connecting element is lifted off and attached to a holder provided at the front end of the wagon. It differs from this in the case where the is equipped with such a device for mixed coupling Wagon on a wagon with an automatic coupling ■, the wagons are to be coupled apart from one another at a suitable distance

/ Device approached, then the transition coupling of / for mixed coupling is removed from its holder and inserted into the coupling claws of the automatic coupling; then the lever carrying the transition coupling piece is inserted with its pin into the open slot of the member carrying the clamping spindle and locked by means of the locking piece

In the device according to the invention for mixed coupling, when it is used as a screw coupling, additional parts hanging on the coupling rod and not used for this type of coupling are avoided. Such a coupling is not only easier and simpler to operate, but is also significantly quieter and more robust than known couplings of this type, especially when they are used as a screw coupling, the number of jolts transferring freely oscillating

and parts rubbing against each other considerably reduced is.

A very particular advantage in the operation of the device according to the invention is that the operator does not use the entire weight of the screw coupling for attachment each time it is coupled on a towing hook and consisting of a transition coupling for connection to an automatic coupling Device has to be manipulated, as the transition coupling piece when not in use together with the attached lever is detachable from the coupling. The transition coupling piece is only then used by removed from its holder and connected to the coupling device, if the screw coupling trained part of the device according to the invention is not brought '. So the operator has either the weight of the screw coupling or the weight of the transition coupling piece and attached to it Manipulating levers, depending on which coupling case is currently given, but never both coupling parts of the device together, as in the known devices for mixed Domes are the case.

An embodiment of the invention is shown in several variants on the accompanying drawing shown. Show it:
