Makeshift coupling to be suspended from the towing hook of the ordinary railway vehicle coupling

an automatic central buffer coupling

Addendum to patent 549

Patented in the German Empire on July 6, 1933 The main patent started on October 1, 1931.

The invention relates to an improvement of the auxiliary coupling according to the main patent, which makes it possible to use the draw hook coupling without the coupling head to have to remove the makeshift coupling.

For this purpose, the coupling head hung on the draw hook becomes the makeshift coupling set up in such a way that, as is the case with auxiliary buffer couplings of other types

ίο is known to use the tow hook if necessary opposite is brought into a hanging position and in this position the tow hook for enables the attachment and operation of an ordinary screw coupling.

For such a use of the makeshift coupling, all essentials should be retained Characteristics of the coupling according to the main patent that part of the auxiliary coupling that encloses the draw hook like a box, by means of a bolt located below the draw hook, articulated with one on the vehicle frame (Buffer beam) attached bearings are connected. After removing the through the walls of the box-shaped Part of the makeshift coupling and through the draw hook mouth and through the draw hook eye guided bolts, the box-like part of the auxiliary coupling can then be folded down vertically and hangs down on the vehicle.

The springs provided for the makeshift coupling according to the main patent, which are used for Resetting of the coupling head pivoted out of the vehicle's longitudinal axis into this serve, are, as in the execution according to the Flauptpatent, on clamping bolts that however, in contrast to the version according to the main patent, with hinge pins connected to the dome head. The unconnected end journals of these clamping bolts protrude through downwardly open slots of the part on which the springs are in the position of use Support located dome head, pass through and step out of these slots when the dome head is pivoted down. When the dome head is in the position of use, they are secured in the slots by cotter pins.

*) The patent seeker indicated the following as the inventors:

Dipl.-Tng. Wilhelm Kaiser and Dipl.-Ing. Hans Dalke in Berlin-Lichtenberg.

In the drawing the auxiliary coupling according to the invention is illustrated in Fig. 4, namely show:

Fig. Ι those in the state of use Dome head in side view and

Fig. 2 shows the side view of the auxiliary coupling in the position that it is in when using the Draw hook coupling occupies.

Fig. 3, 4 and 5 show details explained in more detail below.

The side walls of the part g , which is connected to the projections b of the dome head o by pegs e and surrounding the draw hook / box-shaped part, have under the draw hook, eyelet lugs or tabs q , which are connected by a bolt r to the eyes of a part .9 , which is attached to the vehicle frame (e.g. to the buffer beam).

At the lower of the tab-like lugs b of the coupling head α sits rigidly a bearing block t, with which the clamping bolts n of the springs k are articulated. The bearing blocks t have flat surfaces on which the spring plates of the springs k rest and fix the springs in their position relative to the coupling head. The rear, peg-like end of each of the bolts «protrudes through a slot ν of the part attached to the buffer beam. The slots ν are closed at the bottom by cotter pins w, bolts, screws or the like (Figs. 4 and 5). U can the spring pins with the part of s be hinged and connected with the coupling head a releasable.

If the draw hook coupling is to be used and, accordingly, the coupling head of the auxiliary coupling is to be brought from the position according to Fig. 1 to that according to Fig. 2, the cotter pins are first of all; removed; then the bolts h and i guided through the draw hook mouth or through the draw hook eye are removed, whereupon the dome head moves into the position shown in Fig. 2 due to its weight.

When using the auxiliary coupling, care must be taken that the on the Tensile forces exerted on the coupling head can only be transmitted through the draw hook

for which purpose either the bolt r is removed or the eye of the part g or of the bearing surrounding it is designed as an elongated hole.

Claims (4)

Patent claims: ι. At the towing hook of ordinary railway vehicle clutch to be suspended Behelfskupplung an automatic central buffer coupling according to 54g 545, characterized in that the the draw hooks (/) box-shaped enclosing, (h and i) in the position of use of the Behelfskupplung by means of two bolts to the retaining hooks (/) housing part connected ( g) is articulated to the vehicle by a bolt (r), after loosening the bolt connection (h, i) it hangs down vertically with the towing hook and releases the towing hook for attaching the screw coupling. 2. Makeshift coupling according to claim 1, characterized in that the clamping bolts (ti) for the adjusting springs (k) acting on the coupling head are articulated either with the vehicle or with the coupling head and with the unconnected end in downwardly open slots (v ) intervene, from which they can be swiveled out to fold down the auxiliary coupling. 3. Makeshift coupling according to claims ι and 2, characterized in that the open sides of the clamping bolts (u) of the adjusting springs (k) receiving slots (v) by split pins (w), screws, bolts o. The like. Are closed. 4. Makeshift coupling according to claims ι to 3, characterized in that the flat surfaces on the bearing blocks (t), against which the spring plates of the adjusting springs (k) are pressed, secure clamping bolts with their springs against pivoting down, so that the split pins (w ) can remain in the slots (v). 1 sheet of drawings r.rvmtjrii ι in the air
