PATENT OFFICE.

for railway vehicles.

The invention relates to such transition couplings for railway vehicles which is the pulling head of the automatic central coupling (swivel head) and the pulling hook the spindle coupling are pivotable about one and the same vertical bolt, and concerns in particular a device for locking the swivel head.

With transition couplings of this type

ίο the bearing for the bolt, which the swivel head in the working and rest position notices, received from the parts of the pull rod to which the swivel head and the draw hook of the spindle coupling are articulated. On the one hand there is a compact arrangement the transition coupling this part of the tie rod to the swinging of the To enable the draw hook of the spindle coupling including the hanger in the working position, in the direction of the longitudinal axis of the drawbar just a little over the pivot pin of the drawbar hook and swivel head may protrude, and on the other hand, the distance of the mentioned Pivot bolt from the buffer beam with regard to the dimensions given by the car spacing is hold, so you have so far while maintaining the usual shape of the pull rod the locking bolt for the swivel head is housed in the immediate vicinity of the pivot bolt for the swivel head and the towing hook. However, such an arrangement of the locking bolt results in the absorption of the side impacts that occur when driving the dome claw act, a very unfavorable leverage ratio.

The aim of the invention is to provide a transition coupling of the type mentioned at the beginning create in which this disadvantage is avoided. -

In the drawing, an embodiment of the subject matter of the invention is shown, namely shows

Fig. Ι a view of the transition coupling from above; the automatic central coupling is in the working position, but the spindle coupling is in the rest position.

FIG. 2 is a section along 2-2 of FIG. 1.

Figure 3 is also a top view of the transition coupling, but located the spindle coupling in the working position and the automatic center coupling in the Rest position.

The tie rod A passes in a known manner through the buffer beam B and in its forked parts protruding over the latter receives the bolt C, which is prevented from jumping out by suitable means. On the one hand, the coupling head D of the automatic central coupling, the shaft D ^{1 of} which comprises the pull rod A like a fork, and on the other hand the pulling hook E of the spindle coupling, the eye E ^{1 of which} lies between the fork arms of the pull rod A, rotates around the latter. At

the towing hook E , the links of the spindle and the safety coupling are arranged in a known manner.

The part of the tie rod A protruding from the buffer beam is bent at the side to form a horn a ^l which ends in one eye. The eye of the horn a ¹ is intended to receive a locking bolt F. In order to be able to determine the coupling head D in the rest position (FIG. 3), an eye d ' ^{2 is provided on the upper wall of its shaft Z) 1} , which eye can be made to coincide with the eye of the horn a ^1.

To fix the swivel head D in the working position (Fig. 1 and 2) on the one hand a stop surface d ^{3 of} the shaft D ¹ , which is supported in the working position of the swivel head against the bolt F , and on the other hand a stop ^{surface arranged at the end of the shaft D 1} d ⁴ , which rests against a stop α ^{2 of} the pull rod A in the working position of the swivel head D.

The handling and mode of action of the

Clutch is the following: Should the equipped with the clutch vehicle be coupled with a vehicle having spindle clutch, the transfer clutch is brought into the position shown in Figure 3 position and the swivel head D by inserting the key bolt F in the eye d ² and the eye of the. Hornes a ^l noted. If, on the other hand, the use of the automatic central coupling is required, first pull out the key bolt F , then pivot the coupling head D and the draw hook E around the bolt C until the stop surface i ⁴ rests against the stop a " ¹ (Fig. 1), and finally fixes the coupling head D in the working position by reinserting the key bolt F in the eye of the horn a ^1. The coupling head D is then prevented from pivoting in one direction by the stop surface d ³ resting on the bolt F and by the stop surface d 3 resting on the stop a ² Stop surface <f * secured against pivoting in the other direction of rotation.

The two separately arranged stop surfaces d ³ and d * could also be combined in an eye to be attached at the location of the stop surface d ³ , into which the key bolt can be inserted for the purpose of fixing the coupling head D in the working position.

Claims (2)

Patent Claims: 1. Device for locking the swivel head on transition couplings for railway vehicles, characterized in that the pull rod (A) to which the swivel head is hinged has a lateral bend (a ^l ) which locks the bearing for the swivel head in its two positions of use The bolt (F) . 2. Embodiment of the locking device according to claim 1, characterized in that the swivel head in the working position against pivoting in one direction of rotation by a stop surface (d ³ ) supported against the locking bolt (F ) and against pivoting in the other direction of rotation by a stop (a ² ) the tie rod (A) supporting stop surface (d ⁱ ) is secured. 1 sheet of drawings.
