The rack rail I, the ends of which may be mounted in the circumferential slot l3, so that 50 rounded for adapting it to the connecting rails. the driving axle. I, which is acted on by the has over its whole length teeth 3 arranged beblocking pawl 20, is cut oil. from the motor. tween the track channels 2, which teeth are When the vehicle 4 is placed on the rail 30, which formed not on a separate toothed rail but are can swing about the pivots 2! on the support 21,

formed in the rail surface. In order to obtain the vehicle begins to run on account of the in- 55 clination of the rail and its own weight. After reaching the front end of the rail this end is depressed and the vehicle runs on to the rail 3| placed below and sloping in the opposite direction, which is directly connected to a rising rail 32. When it runs over the latter, the previously arranged hinged support 33 is turned by the vehicle in the direction of the arrow and thereby the rack rail l is brought into the position shown in broken lines in Fig. 8 in which it rests on the rising rail 32 by turning round the axle 23 on its supports 26. v

In the meantime the vehicle has 11m back over this rail and impinges on the depressed rack rail I and its teeth 3. The motor I which is under spring tension, is thereby released, the lower slightly rounded edge of the pawl 20 striking against the teeth 3 and releasing the pawl slightly rotating it so that the pawl 23 is radially displaced on the drive l5 from the aperture 24 towards the guiding slot 23 which at the same time results in the movement of the pawl 20, see Fig. 1, caused by the continuous row of teeth 3. The locking tongue 22 is raised on the teeth of the wheel l1 so that the toothed wheel can turn under the influence of the spring tension. The swinging escapement member l8 regulates the uniform running down of the clockwork. In this way the toothed wheel I! comes into engagement with the equally placed teeth 3 and the vehicle climbs in the manner of a rack railway up the inclined rail I.

When the vehicle has reached the-upper half; the rack rail sinks to the support 25- on account of the weight of the vehicle. The support 33 assumes an upright position and supports the rack rail while the vehicle 4 runs on to the rail 33 which has no teeth. As a result, the pawl 23, which has hitherto been raised by the teeth 3;

falls automatically and the rotation of the wheel I! is interrupted on account of the resulting engagement of the tongue 22 in its teeth. The impact of one of the teeth against the tongue also results in a small radial displacement of the pawl which is guided within the esca pement member, which is suflicient to slide the pawl on the drive. I5 from the slot 23 to the aperture 24', and thus ensure its vertical position. The ve-i hicle continues to run under the influence of gravity until it again reaches the depressed toothed rail, after which it continues to ascend again until the motor is run down. I

The body of the figure 8" illustrated in this example consists of a rack rail adapted for overcoming the incline and a series of curved and straight rails and the standards for supporting the rails and the vehicle. After the rack rail 34; which is substantially as described above and runs at a suitable inclination, there follows a curved rail 35 extending from the rail joint I to the joint II over an angle of about 270, which is connected to a curved rail of completely circular? "shape (360) leading to the joint In. The curved until it reaches the rack rail 34 behind the joint VI. Here in the same manner as in the example as illustrated in Fig. 8, the vehicle is unable to overcome the inclination of the rail by the raising of the pawl which releases the motor and by the engagement of the toothed wheel and the toothed rail. The running down and the continued climbing of the vehicle over the rack rail continues until the. running mechanism or the clockwork motor is completely run down.-

The rail strips 4| which in this example are connected by bridge members 40, have oblique walls 42 on each side for better guiding the ve; hicle. The end connection of these rails is effected by means of joint members 43 which have a rounded overlapping 44 with the ends of the strips for being pushed into the rail pieces.

For supporting the rail body, use is made of the resilient stands 45 which are curved over at the bottom to form a foot and which at the top have V-shaped clips 46, the limbs of which fit resiliently into the slots 4;! of the supporting stirrups 48 which are rigidly connected with the rail members.

Of course, instead of the running mechanism described and illustrated, any other driving motor may be employed while retaining the above-described automatic engaging and. disengaging mechanism. Thus, for example, it would also be possible to build into the vehicle an electric motor acting ona driving axle which when fed from the pocket lamp battery or the like would remain in circuit as long as the pawl was sliding over the teeth of a suitably insulated rack rail I or 34.

What I claim is;

1. A toy railway vehicle for use on a track having a toothed rail for at least a part of its length, driving means and automatic locking and releasing means therefor mounted on said vehicle, said means comprising a motor, a pawl adapted to come in contact with the teeth of the rail, a memher having an aperture in which the pawl is mounted, adriving axle, a pinion thereon driven by the motor, the driving axle extending through a slot of the pawl, a toothedwheel keyed to said axle and adapted to engage in the teeth of the rail,-a tongue on the pawl adapted toengage with the teeth of the wheel to lock said wheel when the pawl is in its lower position and to release said wheel when the pawl is lifted by impinging against the teeth of said rail. A toy railway as claimed in claim 1, characterized by the feature that the guiding slot in the pawl has an eccentric part in which the driving axle engages when the pawl is depressed.

3. A toy railway as claimed in claim 1, in which the teeth are pressed out of the rail.

4. A toy railway as claimed in claim 1, and having tilting rails which, together with the toothed rail, are pivotedand a supporting member for the toothed rail which folds at the impact of the vehicle or when the vehicle :runs over the tilting railj 5. A toy railway as claimed in claim 1, having a plurality of straight and curved rail sections arranged to form a suitable figure in which said toothed rail leads to the highest point of the figure, and having from said highest point to the lowest point of the toothed rail a sufficient drop to convey said vehicle over said figure back to the toothed rail.
