With the present combination of a buffer with an automatic rail car coupling half of the head plate has a convex, half a concave shape and is fastened directly to the drawbar by means of screw bolts and carries a pin on which the coupling member is rotatably arranged. The latter is enough with a flat head up to the top plate of the buffer, which is provided with an edge cutout, in which the stem of the coupling link lies. In addition, the top plate of the buffer has opposite the head of the coupling link of the adjacent carriage through a vertical slot which the head of the coupling link passes after the latter at the additive first makes a quarter turn around its longitudinal axis, making the previously horizontal standing head vertical, d. H. parallel to the slot in the head plate of the Buffers adjusts. Once the head of the coupling link through the slot in the head plate of the buffer has passed through, the coupling link is restored by a weight turned back a quarter turn so that the head is no longer out of the slot can resign. To uncouple the weight must be lifted by hand and the coupling link as a result, it can be turned back a quarter turn around its longitudinal axis, so that the flat head is parallel to the slot in the head plate of the buffer.

The buffer consists of the upper and lower frames A ¹ and A ² , which have hub-shaped parts A ¹⁰ at the rear, which are firmly connected to the front end of the tie rod D by the bolt D ^1. At the front, the frames carry the vertical buffer plate A, which is designed in one half A ^h concave and in the second half A ⁶ convex. In the first part there is the vertical slot A ³ , in the second part an incision Α ^η is made from the outer lateral edge, which ends in a round cut-out A ^s.

The frames A ¹ and A? have eyes A ⁹ , in which a vertical bolt C is secured in its position by means of a liner C ² , on which the coupling link B sits, the hub B ^{2 of} which is provided with an interlaced slot B ¹ , so that the coupling link is simultaneously rotated around its Longitudinal axis can be pushed forwards or backwards. The stem B ^{3 of} the coupling link rests in the cutout A ⁸ and carries a flat, mushroom-like head B * at a small distance in front of the head plate A. A lever B ^% loaded with an adjustable weight B ^{6 is} attached to the hub E ^{2 and} usually maintains the coupling element in such a position that the flat head 2? ^{4 is} horizontal

and is in the outermost advanced position.

If two carriages provided with the coupling described above travel together, the horizontally lying heads B ^ first collide against the concave part A ^{5 of} the opposite buffer plate A, whereby the coupling links A are pushed inwards. According to this occurs when pushing back the folded slot B ^l a rotation of each .Kuppelungsgliedes about its longitudinal axis; so that the flat head B ⁱ arises vertical and now the opposite Buffer A plate passes through the slot a ^3. The rear edge of this slot is beveled at A ⁱ , so that the weight lever B ⁵ comes into effect and the coupling link B can turn back into its original position before the buffer plates A actually come together;

The Entkuppelung takes place in the manner that lever DAF J5 ⁵ either by hand or by means of a chain to be raised in such a way that coupling members B DAF again by about a quarter turn rotate about their longitudinal axis, whereby the heads B ^ parallel to the slots A ³ can adjust and exit from the latter.

If a car with the present coupling accidentally hits a bumper block or a car with a different coupling, the coupling link B cannot be damaged; the latter then pushes out of the side of the slot A ¹ , rotating around the bolt C accordingly . The stem B ^{a of} the coupling member slides here up to the bar A ^u attached in the extension of a slot edge. The material is then taken up by the buffer plate A. As soon as the head ΰ ⁴ becomes free again, it slides back into its old position ^{through the action of the weight lever U 5} , so that the handle B ³ rests in the cutout A ^{8 again.}

If the rolling stock has different couplings, after removing ^{the pin C 2,} the bolt C is pulled out, the coupling link B is removed and replaced by a suitable coupling chain, the latter link of which is fastened by means of the bolt C which has been reinserted in its place. Since the train then goes directly through the bolts C, the buffer frame rotates around the bolts D ¹ . In this case only the convex parts A ^e then serve as buffer plates.

Claims (3)

Patent claims: ι. An automatic coupling for railway vehicles combined with the buffer, characterized by a coupling link (B) which is guided on the bolt (C) with an interlaced slot (B ¹ ) and which is usually pushed forward by a weight lever (B ⁵ B ⁶ ) in the outermost one Position is obtained, when two carriages move together with the flat head (B * ) protruding in front of the buffer plate (A) hits against the opposite buffer plate, is thereby pushed back and experiences such a rotation that the previously horizontal head becomes vertical and now passes through the slot (A ³ ) of the opposite buffer plate, whereupon the weight lever rotates the coupling member back again and thereby the closure is brought about. 2. In the case of claim i. The coupling marked half concave and half convex buffer plate (A), as well as the fastening of the buffer, which can be rotated about bolts (D ¹ ) , for the purpose of automatic, precise lateral adjustment of the buffer plates in such a way that the coupling can take place. 3. In the case of the buffer plate characterized by claim 2. the edge cutout (A ¹ A ^& ) for the purpose of allowing the coupling member to slide out as soon as the head of the same against a foreign body, eg. B. a bumper, bump. 1 sheet of drawings.
