J. GUEST in BERLIN. Innovations in railway signals.

Patented in the German Empire on August 24, 1880.

With the previously known constructions of optical signals, which are based on the latest Ordinance of the Federal Council with two wings are executed for the handling the same and for their connection with pre-signals evidences highlighted, their elimination the aim of the following improvements.

The two-wing optical signal itself is in a known manner, as shown in Fig. 1 and 2, with an upper, respectively in its rest. Holding position horizontally lying wing and with a lower one in its rest position vertical above its pivot point in front of the mast body standing wing thought.

The innovations on the two-wing signals refer

1. on the adjusting device attached to the signal mast to generate the signals, Figures i, 4, 5, 8, 9 and 10;

2. to those shown in FIGS. 1, 2, and 3 Lantern lift.

The position of the signals should only take place by means of double wire pulls in such a way that the position of the Wing forcibly happens both for the travel signal and for the stop signal. This Principle is carried out consistently with the present adjusting device and the double wire pulls headed up to the wings.

The adjusting device consists of the chain roller R, on which the double wire pull from the adjusting device engages. The two-armed lever b is firmly connected to the roller R; but also the disc ί with the hook and the slot. Above the disk ί a three-armed lever α is attached, the lower leg of which carries the small roller ν. This role ν runs on the periphery of the disc, and s may be the lever a rotation by the hook, in which the roll 1) then ί runs in the slot of the disk.

The lever b is connected to the upper wing at points I and II, the three-armed lever a with the lower wing at points III and IV by wire pulls. If one now thinks of the upper wing in its holding position, i.e. lying horizontally, then the roller R is in such a way that the lever b is vertical and is held in place by the adjusting apparatus, Fig. 1.

If the roller is now rotated in the direction of the arrow, as shown in FIG. 4, the lever b with its wire pull in I will pull the upper wing upwards by 45 °; the other wire pull of lever b, which is connected to the wing in II, remains taut and pulls the wing back into its horizontal position as soon as the roller is turned back. During this rotation of the roller R, the lower wing remains in its rest position vertically in front of the mast body, since the three-armed lever α is not moved because the roller ν runs on the periphery of the disc ί.

If, on the other hand, the roller R, as shown in FIG. 5, is rotated from the rest position in the opposite direction, the upper wing is again pulled upwards by 45 ° by the lever b rotating to the other side, but at the same time by the hook of the disk s the three-armed lever a is turned so that it, with the wires III and IV, pulls the lower wing downwards from its vertical position by 45 °.

When the roll is turned back, both wings are pulled through the corresponding wire pulls pulled back into the holding position.

As a result of the lower wing standing vertically upwards, the distance between the lanterns is proportionate very large.

Attaching and removing the upper lanterns is done with the lantern pull fully pulled down without climbing the signal mast or Not possible without a special step device.

To remedy this problem, the lantern train is constructed so that it can be of any size Distances of the lanterns from one another are permitted without making them difficult to operate.

The lantern lift consists of the two lantern holders /, and / ₂ . Of these, only the lower I _{1 is} connected to the chain hoist in such a way that the upper end of the chain engages a head piece k ₂ connected by two special rods u ic. In this frame, the upper lantern carrier / _{2 is} freely movable on the lantern guide rods ti , but can be firmly connected to I ₁ by the solid rod ζ. If the keeper now wants to remove or attach the lanterns, he pulls the entire lantern elevator down as far as possible; the rod ζ connected to I ₁ by a bolt is released and the upper lantern support / ₂ is pulled down for itself, so that, as shown in FIG. 3, I ₁ and / ₂ lie close above one another and can now be easily operated.

If a special distant signal is to be combined with the two-winged signal, it is necessary On the one hand there is a special signal constructed for this, on the other hand there is the connection to be arranged with the main signal in such a way that the distant signal is only one for both driving signals and gives the same signal.

The signal shown in FIGS. 6 and 7 is so constructed that it works easily and reliably without any wire tension compensation and without the use of counterweights, etc., which are always disruptive to the safe functioning, but stops automatically when the wire tension tires «Represents. The same consists of the iron stand s on which the vertical shaft w in G ₁ and G ₂ is supported. At its upper end, the shaft w carries the disk H with the corresponding opening for the night signal. The shaft rotates with the disk only vertically by 90 ° and shows in the two end positions that the main signal is either on "stop" or "drive".

The position of the distant signal is effected by the main signal with a double wire pull without compensation. The chain roller K, with which the pull wire is connected, has a helically cut hub E ^1, which up to the correspondirenden Curve of the bearing G ₁ and down moved when the verticale shaft w is rotated 90 ⁰ on the bottom surface. If the wire pull is moved back, the shaft slides back down on the curve and turns the disc again by 90 ^° to "stop".

So that the downward movement also takes place reliably and cannot be prevented by friction, etc., the shaft w is provided with a counter curve E at its upper end and the bearing G _{2 is} designed accordingly. When the signal is withdrawn, the vertical wave is thereby necessarily drawn down.

When the wire pulls tire, the chain falls out of the roller and the signal disc H , which is on "drive", slides down the curve under its own weight and turns to "stop".

The lift to be transmitted from the main signal to the distant signal is possible with the two-winged one Signals no longer transmitted in the previously known manner. The wire pull, which one the main signal, moves, as described above, from a rest position two directions, so the distant signal moving in only one sense would not be direct can ask.

As indicated in the drawing, Fig. 2, a chain roller r is now attached to the shaft of the upper wing and the line from r is guided over the small guide rollers r _t r _tl after the distant signal. Instead of the roller r shown , a horizontal balancer and instead of the guide rollers r, r _u angle levers can be used, which achieve the same purpose, but also allow stroke regulation.

In both cases the movement of the upper wing, which is used for both main track, as well as for the diversion track is provided, the distant signal to "free ride" resp. pulled to "stop" (see Figs. 8, 9 and 10).
