    In the following, the invention is further elucidated on the basis of non-limiting exemplary embodiments with reference to the drawing which shows in:

    FIG. 8-12 concern role type NSE, fig. 13-18 type EBI.
    FIG. 1 shows a railroad with two carriageways next to each other and an overhead line supported by overhead line portals 26.
    FIG. 2 shows a switch viewed from the front. The circle indicates the area where the tongue tip is located. The tongue striker of the tongue rail on the right is clearly visible.
    FIG. 3-7 are intended to clarify the most important parts of a bill. The most important parts of a single switch, shown in Fig. 3, are: stop rail 5; front switch 1; back side switch 2; tip piece 3; string rule or check rail 4; root end 6; left tongue 7; right tongue 8; tongue pointed roller 9; lifting back 10; sliding chair 11; tongue ear 12 for control rod; tong ear 13 for drawbar.
    FIG. 4 shows a head view seen from the switch front and FIG. 5 shows the plan view of FIG.
    .
    The tongue on the left or right forms the tongue movement (left or right) with the corresponding stop rail.
    In Fig. 3, the right tongue 7 is the adjacent tongue and the left tongue 8 is the lying tongue. This changes by switching the switch.
    In order to make the movement of the tongue easier, so-called sliding chairs are fitted under the tongue (see Figs. 4-7). These are flat steel plates on which the stop rail is fixed and immovable and the tongue can slide over it. These sliding chairs must be sufficiently clean and greased to minimize the sliding resistance with the tongue. The tongues are provided with a lifting device at the tips. This reduces the friction of the tongue on the sliding chairs during the transfer and also ensures that the tongue remains in place while riding the switch.
    The lifting of the tongues is achieved by attaching a roll to the tongue tip by means of a stud. This roll rolls over a lift that forms part of the corresponding sliding chair. Only the sliding chair that is associated with the tongue tip is equipped with a lift.
    Two tongue ears are provided on the tongue tip (see Fig. 6) for engaging a control rod near the tongue tip and a pull rod slightly further away from the tongue tip.
    FIG. 7 shows a schematic end view in cross-section of the detailed area of the switch encircled in FIG. 2 with the stop rail 5 on the left, against the left side of the soul of which a heating element 15 is placed to keep the switch frost-free. To the right is the tongue rail 7 which can slide to the left and right (represented by the horizontal arrow). Below the tongue rail 7 is the sliding chair 11 on which the tongue rail 7 is supported.
    FIG. 8 + 9 show in sectional side view and exploded perspective view an example of the roller 9 (type NSE) with integral bearing, and on both sides a spacer seal ring 22. These rings 22 can be identical or in thickness (the dimension in axial direction, in other words in the direction of the axis around which the bearing turns) differ. For example, one has in stock rings 22 of three different thicknesses whereby, with the same thickness / width (the axial dimension) of the assembly of two rings 22 and one roller 9, three different compositions can be formed around the roller 9 in three different axial positions to be able to put on the tongue. Preferably, only a single width (the dimension in the axial direction) of rolls 9 is in stock. For example, the fitter carries with him a set comprising a single roller 9, two rings 22 of identical thickness, one thinner ring 22 and a thicker ring 22. FIG. 8 shows the section along the line A-A of FIG. 9.
    Use of the rings 22 and the roller 9 ensures a minimum number of parts. However, a ring 22 could be divided into two or more thinner, separate rings.
    FIG. 10-12 show, in side sectional view, a front view and a perspective, an example of the ring 22. FIG. 10 shows the section along line A-A of FIG.
    11. The side with the recess (in this example with depth 0.4 mm) is applied facing the roll 9. The annular shoulder 16 surrounding the recess on the radial outer side provides a sealing surface for sealingly cooperating with the corresponding annular region of the roller 21. This ensures a good seal on and / or a good centering on the roller 21. The roller 9 has a matching axially protruding shoulder that snugly fits into the recess of the ring 22. With its hole, the ring 22 maintains a small play with the shaft on which the tongue roller is inserted. The ring 22 thus rotates with low friction on this shaft which is located on the tongue tip and can also slide over this shaft to some extent and possibly wear on it. The tongue tip overlaps with the tongue rail and is mounted on it.
    FIG. 13-16 show an alternative example of the roller body 9 (EBI type). FIG. 16 shows the section along the line A-A of FIG. 15. The outer surface of the bearing housing 9 forms the roller running surface, which is preferably cylindrical or parallelepipedic. A needle bearing 23 is preferably used, but another type of sliding, rolling or rolling bearing is conceivable. With assembled roller body 9, the needle bearings are visible from the outside.
    Preferably (and as shown) there is a single bearing housing 9 which comprises at least or exactly one or two inner bushes 24 and at least or exactly one or two bearings 23, the bearings 23 preferably being axially narrower than the inner bushes. Preferably, the inner bushes 24 lie substantially or completely against each other and / or the bearings 23 are spaced apart from each other, for example kept at a distance by an internal, radially inwardly projecting shoulder of the bearing housing 9. Bearing housing 9, bushing 24 and bearing 23 are preferably placed coaxially.
    The inner bushes 24 are kept at a distance from the bearing housing by the bearings 23, preferably also at a distance from the possible internal shoulder of the bearing housing 9.
    From the position as shown in Fig. 13 the bushes 24 and bearings 23 can be slid axially free inwards into the bearing housing and are prevented from sliding again axially outwards by, for example, the rings 22 or 25.
    FIG. 14 shows the bearing housing in cross-section, with preferred dimensions, FIG. 15 the completed assembled roller body 9 in end view and FIG. 16 in cross-section from the side. Numeral 17 refers to a peripheral recess which at the end face provides a cylindrical protrusion to the bearing housing with a diameter approximately 5 mm smaller than the outer diameter of the bearing housing.
    This roller body of EBI type can be mounted on the shaft of the tongue tip without the use of sealing rings.
    FIG. 17 + 18 show an example of the distal end ring 25. FIG. 17 shows the section along the line A-A of FIG. 18. The ring 25 is type D48x4. The roller body 9, possibly with a sealing ring 23 on its proximal and / or distal side, is retained by this end ring 25, which is preferably held in place by a locking means. The locking means preferably biases the distal end ring in the axial direction toward the head end of the tongue tip.
    The outer diameter of the distal end ring 25 and of the cylindrical protrusion on the bearing housing 9 are the same.
    When the end ring 25 is used with the tongue pointed roller 9 of Figs. 13-16, the contact surface 16 comes to bear against the longitudinal end face of the cylindrical protrusion bounded by the peripheral recess 17.
    FIG. 19-26 show photographs of embodiments of the invention by way of example. FIG. 19-25 concern role type NSE, fig. 26 concern role type EBI.
    FIG. 19-22 show the free end of a tongue tip with a tongue tip roller in various stages of the assembly.
    FIG. 19 shows how the proximal spacer seal ring and the bearing are mounted on the shaft located at the tongue tip. Note that the distal part of the axis is rejuvenated.
    FIG. 20 shows how the distal spacer seal ring is then placed on the shaft and reaches the rejuvenated part of the shaft. The radial positioning of the distal spacer seal ring and the shaft is clearly visible.
    FIG. 21 shows how the ring D48x4 (washer) is subsequently placed. The distance (in other words, to the right) of the washer is the transverse hole for the locking pin to be inserted into the shaft.
    FIG. 22 shows how the split pin is inserted into the shaft in the transverse hole and its ring is flipped so that the bearing is secured to the tongue tip. A stable unit has been formed.
    FIG. 23-25 show an example of the tongspireroll, built into a switch on location in a railroad track.
    FIG. 23 shows a photograph of a tongue pointed roller built into the switch, the tongue rail closed. The stop rail is on the right. The shaft on which the tongue spike roller is mounted runs parallel to the longitudinal direction of the tongue rail. It is visible how this shaft is mounted on the tongue tip.
    FIG. 24 shows a photo of the same switch, on the open side. The drive is at the top right, the stop rail is on the left (only the rail foot is visible). The tongue-pointed roller runs over the known profile (so-called hill chair), so that, starting from one or the other extreme position, the roller when moving to the opposite extreme position, runs over an ascending and then descending surface of the profile and subsequently into the to reach the opposite extreme.
    FIG. 25 shows a detail of the roll and its near surroundings from the previous two photos (FIGS. 23-24). Between the split pin and the end face of the tongue tip the roller body is located on the axis of the tongue tip with a sealing ring axially on one side and a sealing ring on the other side and an end ring near the split pin. These elements lean directly against each other.
    The photo of fig. 26 shows in an illustration comparable to the previous photo (fig. 25) an alternative tongue-pointed roller (type EBI).
    The tongue pointed roller shown in Fig. 26 consists of a roller body and an end ring 25 (see Fig. 18), both inserted on the axis of the tongue pointed. The split pin rests directly against the end ring, which rests directly against the roller body, which rests directly against the end of the tongue tip.
    FIG. 27 shows an enlargement of FIG. 5 for explaining the tongue tip 30, the shaft body 28 axially projecting from the tongue tip 30, the distal end 29 of the shaft body 28 and the retaining means 27 detachably mounted on the distal end 28 and with which the tongue pointed roller 9 and associated rings 22 and 25 are held in place.
    Sizes indicated in the drawing are in millimeters unless otherwise indicated. One or more of these sizes may be 10 or 20% and / or 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9 or 10 millimeters higher or lower.
    The invention thus relates, for example, to a tongue pointed roller for mounting on a tongue pointed point of a switch, possibly composed of rings and a roller between them; a switch equipped with the inventive tongue pointed roller which is inserted on an axis extending axially from the tongue pointed; a switch in which the tongue-tip roller is supported directly or through the intervention of a ring mounted on the axis of the tongue-tip, against the head end of the tongue-tip, from which end-end axially protrudes the shaft on which the tongue-tip roller is inserted; a switch with an axial side thereof away from the tongue tip on the axis of the tongue tip and locking means and / or biasing means, such as a split pin, which encloses the tongue tip roller axially with the tongue tip and / or biases towards the tongue tip; a switch and between the locking or pretensioning means, such as a split pin, and the tongue pointed roller (1) there are one or more rings which are inserted on the axis of the tongue pointed; a set of a tongue-roller and rings in different thicknesses, for example three different thicknesses, for the tongue-roller or the switch of the invention.
    The features disclosed herein can be taken together individually in any other conceivable combination and permutation to provide an alternative to the invention. Also included are technical equivalents and genuses or generalizations of the measures disclosed. A measure of an example is also generally applicable within the scope of the invention.
