  The present invention relates to a multi-purpose hitch for a railway vehicle comprising a piece of shape that can be inserted into the coupling jaw of an automatic hitch with a central buffer, on which part is hinged a intermediate part in which is guided a traction link. Versatile couplers are already known for coupling railway vehicles to

  an automatic central buffer coupling and vehicles

  equipped with a screw coupling and a draw hook

  tion. Such versatile teams are mainly composed of

  cipally a piece of shape adapted to the contour of the jaw of the head of the automatic coupling with central buffer, a piece that can be introduced in this

  jaw and which includes, on the one hand, a means of

  to prevent this piece from escaping

  of the coupling tongue of the central buffer coupling

  tral and, on the other hand, connecting elements to allow attachment in the towing hooks of the screw coupling and tow hook (DD-WP 71

284; 93,515).

  The disadvantage of these solutions lies in

  the fact that these multi-purpose teams are

  autonomous and must be transported inde-

  railway vehicles to be assembled by multi-purpose couplers or must be stored

  separately and allow operation without inci-

  tooth for all cases of hitches to be expected in the

  time and in space, to be available in

enough.

  The present invention proposes to create a

  multi-purpose hitch for a railway vehicle

  the coupling of Willison-type center-buffer automatic rail vehicles to screw-hitch and draw-hook rail vehicles, and which can be mounted simply in an automatic central buffer coupling, so as to

  avoid to users to set up in the con-

  turn of the jaw of the coupling head belonging to the automatic coupling with central buffer, effort which

  Until now it was necessary to raise the

Versatile lage.

  The present invention proposes to create a multi-purpose hitch of the above type which remedies the

  disadvantages of the state of the art and may

  use during the long period of transformation of railway vehicles to move from the tow hitch and tow hook to the central hitch automatic buffer, without occupying the necessary space for other elements of a wagon and while allowing mounting directly on the coupling head of the automatic central buffer coupling without disturbing the coupling of

  two automatic couplers with central buffer.

  For this purpose, the invention relates to a

  of the above type, characterized in that at the

  In the form of the shaped piece, located on the side of the traction claw, an arm projecting from the coupling jaw has been formed in a horizontal plane and which is adapted in the vertical plane to the tilting kinematics falling inwards. multi-purpose hitch, arm with vertical dowel pointing upward

  and at the free upper end of this stud is ar-

  an essentially horizontal lever, the other end of which is integrally connected to a vertical axis housed in the bore of the upper rib and in the lower rib of the feed dog of the automatic central buffer hitch, a detachable link being formed between the pin and lever so that the lever can tilt slightly relative to the stud and that at the end of the shaped piece on the side of the hitch lock is fixed a handle protruding forward and out of the hitching jaw of the automatic hitch to buffer

  central, grip that grips when the hitch po-

  lyvalent is not used in a blocking device

  cage with the external contour of the automatic coupling to

central buffer.

  The advantage of the invention resides, on the one hand, in the suppression of the difficult physical work during the attachment of the combined hitch in the jaw of the automatic coupling with central buffer in the case of a mixed hitch or combined, and, in that

  each combined or combined coupling point

  SOE. Embodiment of the Embodiment: The invention will be described below in more detail with the aid of an exemplary embodiment shown in the appended drawings in which:

  - Figure 1 is a view of the hitch po-

  lyvalent in plan view and in rest position.

  - Figure 2 shows the multi-purpose coupling immediately before tilting in the coupling tongue of the automatic central buffer coupling

according to the invention.

  - Figure 3 is a view of the multi-purpose hitch in the coupled state and after hooking in the traction hooks of the traction hitch to

  screws and hooks, in plan view.

  - Figure 4 is a view of the coupling po-

  lyvalent after unlocking, seen from above.

  FIG. 5 is a front view of the

  Versatile lage in the coupled state before hanging

  in the towing hooks of the coupling, the combination

  ble being shown partially in section.

  The shaped part 3 adapted to the profile of the coupling jaw 1 of the automatic central buffer coupling 2 belonging to the multi-purpose coupling

  4, known per se, is present in a horizontal extension

  zontal, the side of the traction claws, an arm 5 projecting relative to the jaw 1 and

  adapted in the vertical plane to the kinematics of

  culement; on this arm, there is provided a bolt 6 ver-

  tical directed upwards. At the upper free end of the bolt 6 is articulated a lever 7 directed mainly in the horizontal direction and which

  can switch only in a limited way; the other

  The lever of this lever is integrally connected in rotation with the axis 8. The vertical axis 8 is rotatably housed in an existing hole 9 of the upper rib 10 and the lower rib 12 of the traction claw 11 of the automatic hinge with central buffer 2 so that the lever 7 can move freely in motion over the traction claw 11. The axis

  8 is locked in vertical translation in the interval

  the between the upper rib 10 and the rib

  lower 12 of the traction dog 11 through

  medium of a locking means known per se, not re-

  present. On the side of the coupling lock, on the shaped part 3, there is provided a handle 13 coming out of the coupling jaw 1. The outer contour of the component

  this of form 3 is adapted on the side of the claw of trac-

  to the tilting kinematics returning from the

Versatile telage 4.

  As follows from FIG. 1, at the outer edge 14 of the traction claw 13 there is provided a locking device 15, snap-in

  automatic, known per se, to block the hitch po-

  lyvalent against any annoying movement when at rest.

  To allow the penetration by

  easy, versatile hitch 4 in the

  coupling tongue 1 of the automatic coupling

  2, the bore 9 is provided with a flange 16 on which the hub 17 of the lever 7 and

  thus ensures guidance. horizontal of the coupling

  worth. The hub 17 and the hub 18 for receiving the stud 6, including the removable link 19, are designed so that the upper edge of the

  thrust claw 20 stays higher than these pieces.

  To tilt the multi-purpose hitch 4 in the hitching jaw 1 of the automatic hitch to

  central buffer 2, the first detachment is

  tif blocking 15 then we tilt by the handle 13

  the coupling 4 in the direction of the coupling jaw 1.

  The possibility of limited tilting in the articulated connection between the hub 18 and the stud 6 ensures that when the tilting is continued in the jaw

  1, the multi-purpose coupling 4 is guided in

  curity between the traction claw 11 and the thrust claw 20. By the pressure exerted on the handle 13 is pushed back the lock in the direction of the locking of the coupling by the shaped part 3 until this piece 3 s presses into the coupling jaw 1 and that the latch returns to its basic position from its rear position. The link of traction

  22, provided in known manner on the intermediate link

  21, can then be hooked into the hook of

  traction 23 of the screw hitch and trac-

tion (Figure 3).

  To open the multi-purpose hitch, we move

  this first of all the lock in its rear position by actuating the lock control not shown here on the automatic central buffer hitch 2. Thanks to the force transmitted by the traction link 22 and the intermediate link 21 on the hitch 4, the latter is pulled out of the jaw 1 in a position that corresponds substantially to that

  shown in Figure 4. The latch can then fall back

  ber in its basic position at the front. After decreasing

  chage traction link 22 relative to the hook 23 of the screw coupling and traction hook, one

  can again swing back the polyvac

  slow 4 using the handle 13 in the position of

  rest corresponding to Figure 1 and block this

  using the locking device 15.

  According to another characteristic of the invention

  the axis 8 is provided below the upper rib.

  10 of the feed dog 11 of the automatic coupling with central buffer 2 of a security means

  prohibiting the vertical translation of the axis 8.

  According to another characteristic of the invention

  the lever 7 can tilt over the upper surface of the feed dog 11 and without touching

this claw.
