Patentirt im Deutschen Reiche vom 25. April 1893 ab.Patented in the German Empire on April 25, 1893.

Die vorliegende selbstthätige Wagenbremse ist so hergestellt, dafs sie, falls die Kuppelung der Wagen zufällig brechen und die Wagen von einander getrennt werden sollten, sbfort selbstthätig auf jeden Wagen durch die ihr innewohnende lebendige Kraft einwirkt.The present automatic wagon brake is made in such a way that, if the coupling the car should break accidentally and the carriages should be separated from each other, sbfort acts automatically on every carriage through the living force inherent in it.

Fig. ι der Zeichnung zeigt den Grundrifs einer solchen Bremse, theilweise im Schnitt, an einem Wagen, Fig. 2 die Seitenansicht einer Lokomotive und eines Wagens mit dieser Bremse, Fig. 3 einen waagrechten Schnitt durch das Gehäuse der die Bremsung einleitenden Federn, Fig. 4 eine andere Stellung der Federn des Gehäuses und Fig. 5 eine Abart der Gehäuse- bezw. Federanordnung.Fig. Ι of the drawing shows the basic pattern of such a brake, partly in section a carriage, Fig. 2 is a side view of a locomotive and a carriage with this Brake, Fig. 3 is a horizontal section through the housing of the initiating the braking Springs, Fig. 4 shows a different position of the springs of the housing and Fig. 5 shows a variant of the housing respectively Spring arrangement.

Auf einer der Achsen 2 des Wagendrehgestelles "i ist der Reibungskegel 3 befestigt, und auf dem Lagerstück 6 ist der Hebel 8 drehbar, dessen einer Arm 9 gabelförmig ist und eine auf der Achse verschiebbare Hülse 5 umschliefst, mittelst welcher der auf der Achse lose drehbare Hohlkegel 4 an den Reibungskegel 3 herangedrückt wird, um mittelst Kette 10, Stange 11 und Hebels 12, Fig. 1, die Bremsbacken anzuziehen.The friction cone 3 is attached to one of the axles 2 of the wagon bogie "i, and the lever 8, one arm 9 of which is fork-shaped, is rotatable on the bearing piece 6 and encloses a sleeve 5 displaceable on the axis, by means of which the one on the axis loosely rotatable hollow cone 4 is pressed against the friction cone 3, by means of a chain 10, Rod 11 and lever 12, Fig. 1, the brake shoes to attract.

Die beiden isolirten Kupferdrähte 13 führen an dem Wagen vorbei. Ihre Enden sind zwischen den Wagen passend verbunden und die Drähte führen weiter nach der Lokomotive zu einer kleinen Dynamomaschine 15, die auf geeignete Weise betrieben wird. Von der Dynamomaschine führen die Drähte nach dem Stromschlufshebel 14, mittelst dessen der Strom vom Lokomotivführer in der gewöhnlichen Weise geschlossen und unterbrochen wird. Unter jedem Wagen laufen zwei isolirte Drähte 16 von den Hauptdrähten 13 nach einem verschlossenen Gehäuse 17, in welchem ein elektrischer Motor 21 sich befindet. Auf der Achse 2 ist zwischen dem festgekeilten Reibungskegel 3 und der Hülse 5 der Kuppelungshohlkegel 4 verschiebbar, der mit einem Rand ig versehen ist, welcher das Hineinfallen von Schmutz zwischen die Kegelflächen der beiden Kuppelungshülsen verhindert.Lead the two insulated copper wires 13 past the car. Their ends are matingly connected between the car and the Wires lead further after the locomotive to a small dynamo machine 15, which is on suitable Wise operated. The wires lead from the dynamo to the Power switch lever 14, by means of which the power from the engine driver in the ordinary Way is closed and interrupted. Two insulated wires 16 run under each carriage from the main wires 13 to a sealed housing 17 in which an electrical Motor 21 is located. On the axis 2 is between the wedged friction cone 3 and the sleeve 5 of the coupling hollow cone 4 is displaceable, the ig with an edge is provided, which prevents dirt from falling between the conical surfaces of the two Coupling sleeves prevented.

Auf dem als Kettentrommel ausgebildeten Theil des Hohlkegels 4 ist das eine Ende der Kette 10 befestigt, deren anderes Ende an die Stange 11 angreift, die, wie beschrieben, mit dem Bremshebel 12 Verbindung hat, durch welchen die Bremsschuhe gegen die Räder gezogen werden. Die Kette 22^a am Ende der Stange 22, die, mit dem einen Arm des Hebels 8 verbunden ist, greift an die Triebwelle 2i^a des Elektromotors 21 an.On the part of the hollow cone 4 designed as a chain drum, one end of the chain 10 is attached, the other end of which engages the rod 11 which, as described, is connected to the brake lever 12 by which the brake shoes are pulled against the wheels. The chain 22 ^a at the end of the rod 22, which is connected to one arm of the lever 8, engages the drive shaft 2i ^{a of} the electric motor 21.

Der Stromkreis ist für gewöhnlich geschlossen, wobei der elektrische Motor 21 die Stange 22 angezogen und den Hebel 8 derart eingestellt hält, dafs dessen Hülse 5 nicht gegen den losen Kuppelungshohlkegel 4 drückt.The circuit is usually closed, with the electric motor 21 the The rod 22 is tightened and the lever 8 is held in such a way that its sleeve 5 does not counteract the loose coupling hollow cone 4 presses.

Will der Lokomotivführer bremsen, so hat er nur mittelst des Handhebels 14 den Stromkreis zu unterbrechen, wodurch die Stange 22 vom Elektromotor 21 freigegeben wird, während eine Feder 23, die mit dem äufseren Ende des Hebels 8, der Stange 22 entgegengesetzt, durch Drahtseil oder Stange 26 verbunden ist, die Stange 22 nach entgegengesetzter Richtung zieht. Der Gabelarm 9 der Stange 8 verschiebt dabei den Kuppelungskegel 4 gegen den auf Achse 2 festsitzenden Kegel 3,so dafs sich der Kegel. 4 mitdreht,If the engine driver wants to brake, he only has the circuit by means of the hand lever 14 to interrupt, whereby the rod 22 is released from the electric motor 21 while a spring 23, which with the outer end of the lever 8, the rod 22 opposite, connected by wire rope or rod 26, the rod 22 to the opposite Direction pulls. The fork arm 9 of the rod 8 moves the coupling cone 4 against the cone 3, which is fixed on axis 2, so that the cone is. 4 turns,

Claims

and with this rotation, the brake chain winds itself on the cone 4 and braking takes place.

The spring 23 can be arranged in various ways; but one arranges them appropriately in a cylindrical housing 24 provided with end caps. A displaceable piston 25 is mounted in the housing 24, on which according to Fig. 3 and 4, the wire rope 26 engages, which with the outer End of the lever 8 is connected, while at the opposite end of the lever 8 Housing 24 a wire rope 27 is attached, which with the bent end of a Hand lever 28 is in connection. The housing 24 is expediently in a cylindrical Housing arranged to protect the spring 30 from dirt, which is weaker than the spring 23 and between an end wall of the housing 24 and an end wall of the outer housing 29 is located. The outer end of the hand lever 28 can be latched into a rail 31 provided with incisions to hold the lever in position in both directions.

The end of the cranked hand lever 28 is usually held lying to the right, the lever pulls the housing 24 in this direction and the springs 23 and holds 30 compressed (Fig. 3).

If now the circuit is interrupted and the lever 8 freed from pulling the rod 22 is, so the spring 23 expands and moves the piston 25 to the right end of the cylinder 24 in position FIG. 3.

The outer end of the lever 8 is thus attracted by means of the wire rope 26 and the coupling sleeve 4 pressed against the fixed friction cone 3, "whereby the brake according to the rotation of the bicycle axis 2 automatically comes into effect. It is from the above it can be seen that this construction is not only able to apply the brakes on the whole Act when the engine driver interrupts the power line, but also, if one of the wagons disengages from the rest of the train or one of the couplings should break, the spring 23 automatically brakes all carriages at the same time, since in In this case the lead wires would ripen and the electric motors of the wagons would stop to act so that the rods 22 would be released.

If the brakes are to be released, the hand lever 28 is turned to the left (Fig. 4), wherein the spring 30 pushes the housing 24 to the left, loosens the wire rope 26 and the The pressure of the lever 8 on the sliding coupling cone 4 cancels.

As FIG. 5 shows, the housing 24 can also be arranged in this way in the outer housing 29 be that the wire rope 26 engages the left end thereof, while the wire rope 27 is connected to the piston 25. The spring 23 then acts in the same way on the lever 8 and the spring 30 can in Omission come.
