The vehicles of suspendedrailways and particularly of high speed suspended railways are so arranged for the purpose of automatic banking on curves that they can swing freely about the upper side of the rail in monorailways or abont an axis below the running gear in double rail lines. Owing to this possibility of free swinging the vehicles will naturally swing not only under the. in,- fluence of centrifugal force, but also under other actions, for example side winds, rail unevennesses and the like. During running on the open line these relatively small swingings are of no special importance and can in general bepermitted.

It is different in the stations. A rapid traflic necessitates not only the raising of the running speed to the highest value, but also the reduction of the standing time in the stations to the lowest possible value. The standing in the stations 'iscontrolled principally by'the time necessary for the exit and entrance of the passengers. Along with the guidance of the trailicon the platform, the number and size of the doors and so forth, the arrangement of the passage be tween the vehicle and platform is the most decisive for the time of trafiic change. The passage must be adapted to personal characteristics Without stairs or large gaps so that the passengers can pass from the platform into the vehicle or vice versa without having, to watch their steps. In double railed surface railways or in suspended railways without provision for swinging, this can be very simply obtained "by suitable arrangement of the doors and platform, but no t in monorail suspended vehicles which swing 0 freely. The platform edge in the latter case must be at a distance from the vehicle allowing for the amplitude of swing. Ifthe vehicle is set swinging by the entrance and vehicle and the edge of the platform conof shock or exit of passengers this distance between the stantly changes and leads to delays and accid-ents.

The present invention provides .arrangements which gradually reduce the swinging of the arriving vehicles to. zero and positively guide the vehicles in the station vertically and horizontally.

The invention is illustrated in the ac companying. drawings wherein Figs; 1,. 2 and 3 are views showing transverse crosssections taken through apparatus constructed according to the invention.

In essence the damping of the swinging,

that is the oat-ching of the arrivii1 vehicles is effected by their being provided say on the underside with-guide surfaces or jecting keels, with which they enter guides expanding to meet them, which are arranged opposite them at the line section ends. Figures 4: and 5 of the accompanying drawings, show such guides in plan. Figure 4 the guide visfornied by rollers with. vertical axles. The roller holding frames are advantageously hinged to one another at the points 13 in order to stop the swinging of the vehicles with the minimum amount springs or fluid buffers I-l.

pro-

jarring thereof. The springing The springing 1 or buffing eii'ect increases in stillness towards the station (commencingat 15) and in the stationitselt the springs or buffers-may replaced by an elastic covering of the rollers To compensate the play of the carrying drawings.

awin s kl shows the arrangement of the rollers and l? in the station, in cross sec on. ihe form 18 is so arranged in height that it the same plane as the vehicle floor 19. The gap 20 between vehicle 21 and platform ed 'e can be reduced to a very small value owing to the guidance, only irregularities in the vernal form of the vehicle being allowed While with this first described arrangement a special keel 22 is provided on the vehicle 21, the vehicle 23, Figure has laterally arranged guide surfaces 2% on which engage correspondingly arranged rollers 25. T he angle of inclination of the roller axes is such that the rollers can eli'ect vertical will as horizontal guidance.

lVith light vehicles the forces on the guides are relatively small owing to the great distance of the guide engaging points from the swinging axis. To stop the swinging of the vehicle with the minimum amount of jarring,

which have to be accelerated by the arr; ing vehicle are as small as possible. The buffer device of Figure is designed with this in view. Here there are no rollers for guidin but light guiderails 26, say of spring steel band, which are supported by damping springs or fluid buffers 27 of increasing stiffness towards the station. In this case the vehicles advantageously have coverings of wood or the like, which can be lubricated, on the engaging parts. In the station, in view of running and particularly starting friction, guide rollers QSare provided in place of sliding rails.

In all the examples described above it has been assumed that the guides are to engage on the vehicle body or on the underside of the vehicle. These arrangements have the advantage that owing to the great distance from the centre of swing, the power expenditure is low. Since the forces, particularly with light vehicles, are very small, the guides in certain circumstances can naturally be located "at any other desired part of the vehicle, for example at the top of the vehicle as shown in Figure 6 of the accompanying lhe vertical guidance is effected in this last case by the vehicles bein pressed downwards by the rollers 29 into the position they would occupy when in full loaded condition. Any increase in the size of the vehicle top necessitated by the guiding arrangements forms a compensating surface which decreases the undesirable efiect of side winds.

In the arrangement shown in Figures 7 and 8 a stopping of the vehicle which is entirely free from shock is also obtained. The stopping the vehicle swinging is here effected by pure frictional d Instead of running into a guide. 7 of which the members com 3e ll-Ov rd the station, the vehicle runs before the station onto smooth rollers 30 which pressed by springs 31 against the vehicle with a pressure in accordance with the desired dampin factor. lhe rollers 30 set in rotation by the vehicle running onto them, while in the swinging direction the -on ell ect exists until the swinging disrs. In order that the rollers may be nrotght to the correct speed of rotation in a @101 time, they must bevery lightly con- The friction can be increased by providing either the rollers or the bottom of the vehicle with a known friction covering as used in brake discs.

For exact guidance of the vehicle in the station in a simple manner, instead of the roller arrau ements describedabove, rollers with side ill. -ges shown dotted in Figure i can be used.

The guide rollers in addition to guiding,

can be used for moving the vehicle forward n the station. For this purpose either all he r llers must be driven, or an endless driven said laid over the whole roller track.

- uch an arrangen'ient is of particular importance with propeller driven high speed vehicles, since the propellers must be still in the s vations owing to proximity of the vehicle to the platform and because the propellers are not adapted to operate at low speeds.
