CLASS 20: Railway operations.

Patented in the German Empire on November 8, 1881.

The coupling parts, hook α and b fork rest usually gg on each one of the carrier ¹ and are the same to face to the buffer height differences, slightly inclined but held at different heights, Fig. 4, in such a way, that the carrier g for the Drawbar about 125 mm and support £ · 'for the fork about 65 mm below the pivot point of the parts. At the same time a rag is attached to the carrier g above the towing hook, which connects the towing hook when it is coupled so that it can snap up too high.

At the front, the hooks a are provided with long guides f , which serve to enable them to run onto the lugs c stored in the forks b if there are differences in buffer height. The guides are arranged correspondingly long so that the coupling must take place safely even in the most unfavorable position.

The carriers gg ¹ are laterally rotatable for the purpose that, in the event that the carriage provided with this new coupling is to be coupled to another carriage provided with a more conventional one, the carriers are rotated laterally; the hooks and forks then hang down vertically, and the screw coupling that has existed up to now can be attached to the old towing hook that has been left on the wagon.

Around the carrier gg 'to be able to turn sideways, one raises them with their support rods, ^ V ³ of the frame high, turns them by 90 ⁰ right or left and sets it back into its frame, with the "carrier in their each-time position are fixed by the flat square head of the bolts w w ' ¹ , so that rotation is not possible; for this can only occur as soon as the square of the carrier has been lifted past the square of the bolts.

With the complete introduction of this new coupling the hitherto necessary draw hook would be omitted and a simple piece of bolt would suffice; Furthermore, the carriers gg ^{1 were} omitted, and the old towing hook according to FIG. 5 is forged in place of this. ^:

The coupling of two cars provided with the present device takes place automatically and the process is as follows:

The hooks α run into the corresponding forks b on the lugs c , slide up on the same and collapse. The buffers, which have been compressed by the fabric, only lose their tension in part because the drawn-in draw hooks α prevent them from doing so. It is therefore coupled and at the same time tensioned and, according to the inventor, this greatly reduces the violent skidding of the car.

The outer part of the fork is for the lateral guidance of the hooks with an upward one Approach provided.

On the bolt of the lug c there is a wedged lever d outside the fork b , which is connected to the lever d ¹ by connecting rod e . This in turn is wedged onto a shaft h mounted on the front of the carriage and provided with handles.

If one now wants to disengage the coupled device shown in FIG. 1, one brings

-The handle on the shaft // in the position Fig. 3, where it is held by chain i as soon as it is to remain in that position. This rotation of the shaft caused by 90 ° is followed by lever d ^l and, caused by pull rod e , lever d, as well as the lug c rigidly connected to lever d , which enters the position of FIG. 3, thereby releasing the hook α and lifting it up. The buffers, which were still in a certain tension until then, expand and push the carriages apart.

So that the lever d can only be rotated up to a certain position, the connecting rod e is provided with an extension ν , which, as soon as the lever d has reached the lowest permissible point, lies against the hub of the lever and prevents further movement. The lug c is shown larger in FIG.

Claims (1)

Patent Claims: The combination shown in Fig. 1 to 4 of the draw hook a provided with guide f with the forks b and the rotatable lugs c mounted between the latter,
To support and partially limit the movement of the coupling parts mentioned under 1., the laterally movable supports g and g ^l , or, if this system is implemented, the support shown from the old towing hooks, Fig. 5. In combination with the lug c mounted in the forks the lever d rigidly connected to it, pull rod e, di, e shaft h, the lever d ¹ sitting on this and the handles located on h in connection with chain i, which latter two can also be replaced by appropriately attached weights.
