The buffer head A shown in Fig. 1 and 2 is set up for automatic coupling with a counter buffer of a similar type or with other common couplings of different types; after the engagement of the coupling parts, the. Coupling can be tightened or tensioned in the manner described below. The buffer head can also, instead of the automatic action, be brought into engagement by hand with almost all known couplings or with other buffer couplings and then also tightened or tensioned.

α is. the coupling joint, which is shown in Fig. 3 and 4 by itself; the same is rotatably mounted by means of a bolt a ^l passing transversely through the buffer head A and is prevented from inadvertently sliding out of the bore ^{by a transverse bolt α 2} , FIG. 2, rotatable at the end of this bolt. The joint α can make a considerable rotation around the bolt a ¹ , but is limited downwards in this movement by an extension a ^z , which protrudes downwards on both sides at the rear end and lies under the sides of the buffer head (Fig. 1 ).

b is a hanging bolt which is attached at b ^l to a cover c movable by means of pivot c ^1. This bolt b is moved back as far as is desired, so that the two interengaged Küppelbuffer against each other. to tighten and tighten the coupling. In order to achieve this, the cover c is fastened by means of pivot c ¹ to a carriage or frame d which is displaceable in the cheeks of the buffer head A and which is shown in FIGS. 5 and 6 by itself. The bolt b rests against the cross bars d ^l when it is in its lowest position. The gap between the two cross bars d ¹ is so wide that the coupling joint a passes through with a margin. In the cheeks of the buffer head A there are straight slots e along the length and a square cutout d ³ is made in each of the side walls d of the carriage. Bolts j are inserted through these cutouts d ^B and slots e , the heads f ^{1 of} which fit into the countersink of cutouts d ^a , while the part f ^{2 of} the bolts lying in slots e is square. The carriage d with its pressure surfaces d ¹ d ¹ , the cover c and bolt b is thus inserted in the buffer head so as to be displaceable in the longitudinal direction.

In order to move this carriage d backwards or forwards, a forked lever g is rotatably mounted on both sides of the buffer head A about a pivot g ^2; At the lower end of the lever sides there is a cutout g ^l , which encompasses the bolt f. The pivot pins g * are expediently inserted into the buffer head cheeks with screw threads and the bolts / are secured with cut steel clamping nuts f ^3. When the lever g is rotated forwards or backwards on its pivot g ² , the bolts f and slide. through this the carriage or frame d with

Claims (1)

Cover c and latch b forwards or backwards accordingly; the bolts f have the required clearance in the cutouts g ^{l of} the lever sides. The connection of the levers g to one another is effected by a frame h , the side parts of which h ^l are drilled out like a tube and slide up and down on the lever sides g. A protruding handle / z ^{4 is} attached to each side of the frame h to move the frame back and forth and to raise or lower it. The lever g must of course be able to be fixed in the appropriate position after the coupling has been tightened or relaxed as required. For this purpose, an arcuate rack i is attached to the upper edge of the two buffer head cheeks, which has the fulcrum g · ^{2 of} the lever as its center; the frame h is extended on both sides up to this dental arch i and engages in this dental arch i with appropriately designed teeth h ^e . The arms fr ^{5 of} the frame are widened at the toothed lower end, as are the toothing of the arches z, so that there is a large contact surface between the toothings / j ⁶ and i in order to withstand a tension acting on the coupling joint α and the bolt b . When the frame h is raised, the toothing h ^e comes into engagement with the dental arch i, and the frame can then be rotated freely to one side or the other in order either to tighten the coupling or to loosen it. The fixing of the frame by the interlocking dental arches h ⁶ i can take place not only at the end points of the lever deflection, but also in any intermediate position. The automatic coupling between the two opposite buffer heads takes place in the following way: If the two carriages collide with their head sides against each other, the coupling joint a whose outermost free end is higher than the one on the opposite side becomes , slide up the upper surface of the latter (which is supported by the lugs a ³ ) and, passing between the cross bars d ^{1 of} the frame d , lift the latch b. As soon as the closed end of the link α is under this bolt b , the latter immediately falls due to its own gravity into the interior of the link and through it and thus instantly establishes the coupling. In order to tighten this now, the frame h is raised and the handle / i ⁴ , as described, moved, whereby the bolt b is pushed back with the slide d; then the frame h with its toothing / t ^{6 is} lowered into "the tooth arch i and thereby the coupling is firmly set at the desired point. The outer surface of the lower cross bar d ^{l of} the slide d, FIGS. 5 and 6, is hollowed out in an arc shape, corresponding to the rounding of the coupling element a, so that the forward movement of the slide d is not inhibited. This hollow also serves as a resistance for the link a when the slide is in its outermost position to the front. A chain, which is attached to the cover c by means of the joint c ^{1, is used to uncouple the car.} By tightening this chain, the cover c is lifted and the bolt b attached to it in the hinge is lifted vertically out of the coupling element α. Patenτ claim: A coupling to central buffers, in which a tensioning lever (g) is used for tensioning and releasing, and which is characterized by the following devices in connection with one another: a) one sliding in guides' (e) in the buffer or coupling head. Carriage (if, Fig. 2, 5 and 6), which carries a cover (c) hingedly connected to it and a coupling bar b seated in a hinge-like manner; b) a circular rack (i) attached to the buffer head or coupling head and engaging with the toothed end (h ^s ) of the lever (g) to fix the lever at the extreme end of each stroke or in any intermediate position, and c) a coupling member (a) which is rotatably suspended from the buffer or coupling head and which is provided with lugs (a?) guided past under the head sides, whereby the coupling member is held in such a position that when two carriages are pushed together, the coupling member of one of the the other can slide up.
