schematically modifying the device in order to apply it to prevent the possibility of receiving a train on a busy road, fig. 8 is also a schematic version of the latter device; FIG. 9-schematic-contactor page Selk with switch contact.

The proposed device is made up of travel instruments located between the rails, and of devices interacting with the aforementioned instruments located on a moving train. The track instrument consists of a pivoting lever 2, located in a parallel to the axis of the track and located in a box with a double hinged lid 1; the base of the box is the platform 25, which lies on the supports, which are pressed into the rail track under the block and the sole; on the said platform 25, inside the box, a bearing 26 is installed, in which the axis of the lever 2 rotates. The latter, by spring 3, is connected to a spring mechanism placed in box 27 attached to the platform 25 below. The double hinged cover 1 serves to protect the lever 2 from atmospheric INFLUENCE and malicious translations; Electrical contact plates 10, 10 are insulated from the inner side of the lid, and the closed cover is in contact with each other. The spring mechanism “oetoite” from the closed bark, electromagnet 4 of the swivel wheel 28, which sits on the yudnaya Bei e. Gear wheel 29, driven by the rotation of the drum Bot 17 through the nose of the gear mounted on the same axis with this last gear. 30 and an endless chain 31, worn on both of the above-mentioned gears 29 and 30. To twist the spring 17, there is a gear 16, which interacts with "dogs 15, 15 fastened on the springs of the springs 14, 14, which enclose, like pincers, the flaps of the cover 1, and gesture on associated with them (FIG. 5).

On a moving train, there are two types of devices, of which a device of one type is placed on a locomotive, and a device of another type is on a rear car. The device located on a steam locomotive consists of two vertically movable rods 5, 5, which serve to open the lid 1 of the track instrument and are equipped with rollers 6, 6 on the bottom fender incident on the bevel of the lid flaps; the upper ends of the rods 5, 5 are attached to the bar 7, on which the two shoulders pivot the levers 8, 8, the long arms of which are connected to the retractable rod 9, equipped with a current-collecting device, which is in contact with the contact plates 10, 10, isolated on the flaps of the cover 1 of the track gauge, and connected to the brake brake, etc. The axle of the carriageway is connected by a spring transmission to the bar 13 of the described locomotive device, dog 111, its earrings for the swivel levers 8, 8, with the .sel w, so that when any load .parovoza nahodils mechanism on one and that the distance from the rail. The device located on the rear of the wagon is different from the one described above by the fact that the rod 9, which does not have a current-collecting irile and is not connected with the brake lever, is provided at the lower end with a roller designed to interact with the track lever, 2, with n, e .11 setting the latter into a position that blocks the stage after the train that has entered it, and: it is designed so that it can descend to a much greater depth than such a rod .9 of a steam engine. The operation of the device is as follows: the device located in the rear car of the train entering the section, with its rods 5, 5, opens the cover 1 of the track device located at the beginning of the fenced section; rollers 6, 6, mounted on the ends of the rods 5, 5, overlap the bevels of the valves, which entails lowering the rod: 9, the lower end of which, equipped with a roller, runs onto the turning lever 2; since the rod 9 of the device, located on the rear car, can be lowered to a much greater depth than the same rod of the locomotive device, which unimpededly passed over the entire length of lever 2, the said rod passes over lever 2, pressing it, and through the axis of its rotation, translates the marked 1 st lever into the position blocking the drive: due to the presence of the track lever 2 on one arm 11, which enters the recess on the spring 12 located below the lever lever, the lever 2 is held in position blocking inflection after the train has entered the last step (FIG. 6). In the case of entering the section occupied by the previous train of the next train, the rod 9 of the locomotive apparatus will be stopped at the end of the traveling lever 2, as indicated above. which would cause a deviation of the said rod 9 connected with the brake lever and, therefore, automatic braking of the train. The track instrument, located at the beginning of the fenced section, is unblocked at the moment when the train, which has placed it in the position blocking the stage, leaves the latter and passes over the track equipment at the end of the fenced section. At the same time, the rod 9 of the locomotive device, with its current-collecting device, slides along one of the contact plates 10.10 (depending on the direction of the train's movement), insulated separately on the inner surface of the flaps of the cover 1 of the track, which device is connected to the linear wire; thus, the current source located on the train of the above-mentioned train is connected to the linear wire, through which the current passes into the contact plate of the track device located at the beginning of the section; as the cover of the latter.

is closed, then the contact plates 10, 10 of its sonar are connected with each other, which allows an electric current to pass through the coil of the electromagnet 4 connected to one of the contact plates and from there to the ground, serving as a return wire. The anchor of the electromagnet 4 frees the wheel 28, therefore, the entire spring mechanism; endless day 31 comes into motion

and the lower end of the spring 3 (fig, 1), its fascination with the dog shifting with the depot, which entails the movement of the lever 2 to the initial normal position, allowing unhindered entrance of the train to the stage. The spring 17 of the spring mechanism turns on automatically: when the train enters the stretch, the lid 1 of the track instrument opens twice, the arrival in motion from the instruments located on the train and

rear car; in this case, the springs of the springs 14, 14 fastened with the flaps come in motion, the pawls 15, - .15 of which rotate the gear 16, which sits on the same axis with the drum, which encloses the spring 17, which, therefore, is twisted.

The proposed device may be

used to guard the safety also on station tracks, with a view to preventing the possibility of taking the train to a busy track. FIG. 7 shows a schematic of the device for performing the abovementioned cases: on the main track, at the entrance semaphore, there is a track device mechanically connected with the semaphore wing; The electromagnet 4 of this device is electrically connected to the current source located on the standard and connected to the line wire by means of a switch 32 controlled from the station. In series with the electromagnet 4 on the electrical day, the switch contacts and the contacts of the track arms enclosing, respectively, one or another standard way are included. With the correct installation of the route, the depot closes, which makes it possible to excite the electromagnet 4 of the track instrument located at the entrance semaphore; The lever 2 of this device BLOES the main path and at the same time opens the semaphore; if one of the station tracks was taken, the contact was located under the blocking arm of the lever 2 of the corresponding track instrument.

would be open, which would not allow to unblock the main path and open the input semaphore. In the embodiment of the described device depicted in Figure 8, the semaphore is not opened electrically, but mechanically by the help of cables or the like; the semaphore wing transferred to the open position is held in the designated position by a special dog that is mechanically connected to the electromagnet cortex 18. The semaphore was ruptured mechanically to the track lever 2, which, when opening the semaphore, unblocks the main path to the station; The track instrument in this case has no spring mechanism, n. electromagnet 4, and returns to the initial position, blocking the main path, forcibly when closing the semaphore. The electrical circuit, in which electromagnet 18 is turned on, closes only if the route is not correctly installed or if there is a train on the station track, while electromagnet 18 is energized and releases the semaphore wing, which descends to the closed position under its own weight. In the described embodiment of the device electrical contacts of the traveling devices. fencing1; EX corresponding station paths, are not located under the blocking arms of the levers 2, somehow took place in the first embodiment, but under the opposite points of these levers.

In both versions of the above-described safety fence, the station paths are equipped with an arrow switch equipped with switch contacts, which are connected, as already mentioned, in series between the gauge devices enclosing the standard paths according to the established route (Fig. 9). Each of the above-mentioned contactors consists of a rotary lever 19, which is locked by a switchman with the help of a two-lever lever 20 and carrying two persistent teeth 21 and 22, one of which, depending on the position of the arrow, interacts with a tooth 23 fixed to it. ; In order to release the lever 19, a post 24 is pressed, which is pressed by the projecting part fastened on the frame of the rear car.
