Federal Republic of Germany-Germany (72) Ernst von Hayn, Oberhessen, Federal Republic of Germany (DE) (7 ^) Oy Kolster Ab (5 ^) Movable-tipped junction - Hjärtstycke med rörlig spets is a movable tip which is interchangeable in both directions for contact with fixed wing rails by means of a drawbar acting on it in the drive and which can be locked in both contact positions by a lock of the bar type used in gear levers.

The SE patent discloses such an intersection, in which the hammer-like outer ends of the two bars acting on the tip of the lock alternately rest from the guide slide guide in this recess and thus disengage and engage the actuator or press behind the edge of the lock housing.

According to said publication, both axes of the tip lock are connected directly to the tip base of the junction piece. This may in some cases lead to operational disturbances because on the one hand the tip of the junction and on the other hand the wing rails move longitudinally in opposite directions due to climatic expansion and contraction of the associated rapids, resulting in a change in the position of the tip lock bars. In this case, the lock may become stuck, which must be prevented by adjusting the lock housings manually according to the season, which is known from the locks of the gear tongues.

The object of the invention is to eliminate the drawbacks described above and in particular to avoid the adjustment or arrangement of the lock housings. According to the invention, this is achieved in that the base of the ends of the junction piece is longitudinally displaceable in a special slider, that the slider is displaceable laterally with respect to the base plate of the lock and that the axes of the tip lock are pivotally connected to the slider.

Thus, since the tip of the junction piece is no longer attached to the tip lock in any part, but can now move freely in the longitudinal direction of the track with respect to the lock, sticking of the lock due to Empo movements of the track has been made impossible and lock housing adjustment unnecessary.

According to a further feature of the invention, a slider is placed between the front and rear abutments of the base plate to guide them, the guide surfaces of the slider and the abutments being made according to the movement of the tip of the junction during the change of the circular arc.

A structural example of the invention is shown in the drawing, in which Fig. 1 shows a top view of the intersection tip tip with corresponding parts of the intersection tip tip and Fig. 2 shows a cross-section of the device of Fig. 1, showing the wing rails left in Fig. 2.

The tip 23 of the center block of the junction body or junction body running between the two wing rails 21 and 22 is placed at its base on a slider 24 which guides it in the longitudinal direction. The slider 24 then surrounds the base of the tip 23 as shown in Fig. 1, and does not need additional support due to the suspension on the rail cover. The purpose of the reinforced plate 25 welded to the underside of the base is to increase the lateral guide surfaces and thus to reduce the surface pressure acting during the change and the high pressures occurring in the respective limit position.

The tip is located on the frame-shaped base plate 26 of the lock, which is attached to the sleepers 27, 2B. The base plate has two abutments 29 and 30 between which the slider 24 can move transversely to the track.

Mounting housings 31 and 32 are mounted on the base plate 26, in which a sliding bar 33 of the drive (not shown) and both locks 34 and 35 of the lock are arranged to be moved and locked in a known manner, the hammer-like outer ends of the locks can either interlock with the sliding bar 33. or engage behind the edge of the lock housing, such as the lock 35 of the lock housing 32 in the locked position.

The inner ends of the bogies are articulated to the slider 24 so that the bogies can pivot when moving from an unlocked position to a locked position and vice versa, as is also the case with the hook or road lock of the gear tongues.

For this purpose, the bogies can in principle be connected directly to the slider 24 by means of a pivot pin, but in order to fine-tune the distance between the hammer end of the bogie and the tip of the junction piece, both i

between the inner end of the bogie and the slider 3 a known connector 3G and 37 »of its father, which is lockably connected to the slider 24 and rotatably, i.e. by a joint, to the bogie 34 or 35. These connections are formed as used in the known connector as follows.

According to Fig. 2, both ends of each connecting piece are branched and provided with articulated bolts 3Θ and 39 »of which the smooth articulated bolt 38 is secured by rotation with a longitudinal groove or spring and falling out by a transverse pin, while a hexagonal articulated bolt 39 is

For the articulation bolt 3Θ, the bore made in the beam is provided with a rubber sleeve 40 »vulcanized between two steel sleeves (not shown), of which the outer sleeve has a compression fitting in the bogie, the inner sleeve being secured to the bolt by a longitudinal groove and spring. The purpose of the device plate is to keep the rubber sleeve untensioned when the bogie is in the unlocked position (middle position) and to apply it to the tension in the locking position (turning position) so that a return torque is generated.

The bore made in the connector for the hinge bolt 39 is provided with an eccentric sleeve 41, which can be rotated after the hinge bolt has been removed, thus enabling the above-mentioned fine adjustment. To make this bolt connection untwisted, a wedge 42 is struck between the branches, which is secured on both sides by a bent plate 43 «
