CLASS 2O: Railway operations.

Patented in the German Empire on January 6, 1883.

The lever apparatus shown in Figs has the following purpose:

1. The driving signal for a specific train can only be given if all of The turnouts to be passed are correctly positioned and the threatening signals are locked are.

2. If a train has entered the station, it can be from the same or opposite train No other train in the same direction

- Track guided, d. H. its driving signal can be given before the former has not moved out respectively as long as the exit sign was not drawn and then opened again Halt is reset.

As an example, consider a train station on a single-track railway (see Fig. 13) with a continuous main track I and the alternative track II. For the purpose of passage, crossing and overtaking, entry and exit on both tracks should be possible from every direction. In this case, the apparatus receives two signal levers 5 and S ₁ . With the entry signal S M and the exit signal N are connected in such a way, that is pulled by turning the crank K M to the left to travel, where N remains, while according to the rotation of the right drive N and M indicates hold. This is effected by the previously known, patent no. 20307 protected device and shown in FIGS. 14 and 15. The same is true of S ₁ O and P.

The signal lever, FIGS. 1 and 2, consists of the crank K which drives the roller T. At T , two signal wire pulls attack next to each other, each of which is wrapped twice around the roll and fastened in one place. In the upright crank position the relevant signal is on stop, in the punctured position on drive. Due to the two semicircular flanges / and / Ί on the roller T, Fig. 3 and 4, and the two bolts r and ^ ₁ , which the latter act on the switch lever, four different driving streets are linked to the signal lever, namely:

1. Entry on track I,

3rd exit from track I,

r and r, by means of the handles h and Zi ₁ , hold the roller T immovably in its middle position. By lifting the handle h , T can be turned to the left, whereby the flange / slides under the bolt r and locks the latter.

By depressing h , T can also be rotated to the left and pushes itself over r, Fig. 4. By the same two movements of H ₁ , T can be rotated to the right. In order to make these movements of h and h _x dependent on the switch levers, a disk if is arranged for each bolt r and connected to the bolt by a rod in such a way that the disk is rotated by the hand latch. The latter is only possible if the longitudinal bolt a, which leads past the row of Weiphen levers, can be moved parallel with it. The relationship between R and α is established by the flange F, Fig. 1- and 8, and the two rollers gg ₁ attached to α . By rotating R to the right or left, g and ^ ₁

follow the inclined surface of F and thereby push α back and forth.

The action of the switch lever W on the longitudinal bar α is shown in FIGS. 5 and 6. The washer S is firmly connected to the switch lever W and is provided with two arcuate projections sa S ₁ a for each longitudinal bolt in question, and the longitudinal bolt itself with two corresponding shoulders α A ₁ . In the position shown, α is movable in the direction of the arrow, FIG. 6; α moves in front of s α and thereby holds W tight. ...

In order to be able to carry out the opposite shift of a , W must first be rearranged in that H ₁ finds an obstacle at S ₁ α. After W has been switched, U ₁ can be pushed behind S ₁ a.

For the fulfillment of the purpose mentioned under 2 is for each track in question (here I and II) another longitudinal bolt I and II, similar to that used for locking the switches, is arranged.

These longitudinal bars can BEZW to all eligible R discs. Handle h act while they are unrelated to the switch levers.

The latch for track I is shown in FIGS. 9 and 10, for track II in FIGS. 10, 11 and 12. In the rest position, FIGS. 9, 10 and 11, the two disks R ₁ for the entrance from A and R ₁ for the entrance from B are movable, where R _{1 is} due to the pins In ₁ m ₂ and the inclined surfaces U ₁ U ₁ J would move the two longitudinal bars to the left, R _1, however, by virtue of the pins p _r and pji and the surfaces X ₁ X ₁₁ to the right. The disks R ₂ for the exits to A and R ₁ for those to B are in the rest position by means of the pins tij and η υ respectively. oj and on, which respectively under the latches Nj Nu. . O ₁ Ou grab hold of. If one of the entrances, e.g. B. opened from A to track II by pressing down the handle h , bolt II comes into the position shown in Fig. 12, in which the pin ou can be moved up to o α , which enables the exit of track II according to B. When moving from On to ο α , the pawl Ojj is rotated in the direction of the arrow and, due to its gravity or a spring, falls back into its old position as soon as O ₁₁ comes into contact.

The entry disc R ₁ is locked in relation to track II because the attachment Xj / has pushed itself under the pin ///. With regard to Gleise I remains i? ₄ but movable. The exit to A respectively. the R ₂ disk is kept locked by lug # //. If the train has entered and the entry signal from A is reset to stop, R _{1 can} also be turned back to the rest position, whereby niu falls under the trap Mji . The latter is turned in the direction of the arrow, lets the pin pass nijj and then falls back into the rest position. In an attempt to open the entrance from A to track II again, nijj hits the protruding lobe of the trap Mu- If, on the other hand, R _{s is returned} to the rest position, i.e. the exit from track II to B is stopped, ou slides from position ο α on the left past the inclined surface of the latch O _n and thereby pushes the longitudinal bolt II back into the rest position. The analog movements take place with the other entries and exits of the trains.
