Actuation and monitoring device for Eisenfrahnsipal & Patented in German fteicfte from March 7, 1920.

For this application, the 'Union treaty claimed on June 2, 191 1, the priority on the basis of registration in England on March 27, 1919 according to.

The invention relates to an actuation and monitoring device for railway signals with an electromagnetically actuated clutch mechanism through which the Assignment · of the signal required energy

is transmitted. The essence of the present invention is mainly that in such a device the armature of the Kupphmgsmagneten in Er-. excitement this magnet of a strain

is subjected, which is exerted parallel to the pole face of the magnet, instead of, as usual, at right angles to it. This train or pressure is, as long as the electromagnet is excited, by one of the to coupling part arranged stop (pin or roller) counteracted with a Groove or recess of the anchor joint piece can come into engagement. The one on this ίο The pressure exerted on the joint piece is then applied the point of engagement of the pin or the roller in the groove of the joint piece in an im Stress directed at right angles to the pole face of the clutch magnet dissolved that this magnet can withstand. To a longitudinal displacement of the joint piece to cause it to slide over the pin or roller, causing the armature to move away from the clutch magnet to a short distance. This arrangement can result in a considerable Translation can be achieved because with suitable training of the pen or The groove matching the role is a comparatively small one, exercised by the clutch magnet Apply a very significant amount of tension or pressure to the anchor joint can correspond.

So while here the armature actually does when the electromagnet is not energized are shifted in a direction parallel to the pole face of the electromagnet can, this is not the case with known devices where the anchor on a stationary, next to the pole face of the magnet arranged axis is rotatably attached.

In the drawing, an embodiment of the subject matter is partially Schematic view illustrates, in the application - on a device to operate a signal arm that works with an electric motor, which in turn with a suitable drive to transmit the rotation of the engine a rotatable or swingable disc or a pin wheel is provided by that the signal arm is transferred from one position to the other.

In this drawing, the disc or the pin wheel is indicated at 1, namely in its arrangement in a suitable housing 2, which is also used for actuation Motor 3 and the transmission 4 contains. The disc 1 is with one or more protruding Pins or rollers 5 provided, which when rotating "the disc 1 under the Effect of the motor drive 4 come into engagement with a thumb or shoulder 6 can, which is formed on an angle lever 7. The base of this angle lever is rotatably attached at 8 next to the edge of the disc 1. on a rotatable coupling plate 9, which in turn is coaxial is rotatably arranged with and next to the disc 1. The clutch plate 9 carries a Arm 10, which is rigidly connected to it and at the end of which the signal arm actuating Signal rod is rotatably arranged.

One arm 11 of the angle lever 7 can bump against an adjustable screw 12, which is a stop and also on the Coupling plate 9 is arranged. The other arm 13 of the lever 7 is with its outer End rotatably connected to one end of this joint piece 14, which is a frame or a holder for the armature 15 of a clutch magnet 16 represents. The latter is also arranged on the coupling plate 9 and consists of a U-shaped core 17 with the usual exciter coils. At a point between the armature 15 and the arm 13 of the angle lever 7 is the joint piece 14 is provided with a recess 18 which attaches to a push pin or roller 19 can apply, which in turn is attached to the coupling plate 9. This is in addition to the role with a laterally outstanding stop 20 provided with the moving parts of an air buffer device 21 can come into engagement. The disc is provided with a pawl and a ratchet mechanism 22 for reverse rotation to prevent the disc. A lever 23 which is rotatably arranged on the housing 2 and which is arranged by a lever on the coupling plate 9 Roller 24 can be actuated, is used to monitor certain electrical contacts, their actuation in the following will be described.

The operation of the device actuating the signal is as follows: Suppose that the signal arm is in its usual or dangerous position, with the Clutch magnet 16 is de-energized, the signal arm is in its position below the Effect of the usual counterweight held. If you now wish to have the signal in To bring the safety position, the electric motor is powered to operate the Signal fed by a couple of switch contacts, which are indicated at 25 and the usually closed under these conditions. The engine 3 then comes into action and transmits the rotary motion through its combined gear mechanism 4 onto the disk 1. When it rotates, one of the pins or rollers comes into play S arranged thereon in engagement with the thumb 6 of the bell crank 7 and as a result, strives towards the latter about its pivot point on the coupling plate 9 turn. However, this rotation will go through

prevents the action of the coupling magnet 16, whose exciting windings are connected in parallel to the motor circuit and as a result, powered at the same time

"5 and thereby the anchor 15 on the Hold the magnetic core 17 of the clutch magnet 16 firmly. Accordingly, the engagement causes of the pin 5 of the disc 1 with the thumb 6 of the angle lever 7 one rotation the coupling plate 9 together with the • washer I, the endeavor of the anchor

15 of the clutch magnet 16, to the side To move over the pole faces of this magnet, prevented by the stop roller 19 that is against one side of the ex? Savings 18 of the joint piece 14 sets. The lateral pressure created by the angle lever 7 is exerted on the armature, at the point of contact of the joint piece 14 with the Roller 19 converted into a train that "cause the displacement of the armature 15" seeks, whereby this train by the, attraction force of the coupling magnet i6 " Resistance is offered. The consequence of this is that the angle lever 7, 'the' coupling anchor 15 and the coupling plate 9 as a whole rotate as long as the clutch magnet

16 is energized.

The rotation of these parts is transmitted to the signal through the arm 10 and brings this into its safety position, whereupon the roller 24 of the coupling plate 9 with it the rotatable lever 23 comes into engagement and the switching contacts for the purpose of interruption of the motor circuit opens. At the same time, the movement of the rotatable lever closes 23 a second pair of contacts 26 which are used to short-circuit the motor armature. If you want to let the signal arm take the dangerous position again, the The supply of excitation current to the clutch magnet 16 is interrupted and its armature 15 let go. Now the clutch plate 9 can take up its original position again, wherein the thumb 6 of the angle lever 7 slides over ■ the pin 5 in the disc 1, there the angle lever 7 is now able to rotate freely around its fulcrum 8 as a result of the Release · of the coupling anchor 15. The coupling plate 9 and the parts of the device carried by it consequently return to hers Starting position back.

The structural details described above can obviously be modified considerably without departing from the essence of the invention.
