■ Patentansprüche:■ Patent claims:

1. Einrichtung bei Gleisbremsen zur Erzielung der Profilfreiheit für Lokomotivfahrten, dadurch gekennzeichnet, daß zwei aufeinanderbewegliche Profilschienen, von denen die obere hochklappbar ist, vorgesehen sind.1. Device for rail brakes to achieve freedom of profile for locomotive journeys, characterized in that two profile rails which can move one on top of the other, of which the upper one can be folded up, are provided are.

2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Bremsschienen derart beweglich mit dem Magneten verbunden sind, daß sie durch Seitwärtsbewegung und gleichzeitige Senkung aus dem Profil herausgebracht und durch Erregung der Magnete wieder in Bremsstellung zurückgeführt werden.2. Device according to claim 1, characterized in that the brake rails are so movably connected to the magnet that they are by sideways movement and simultaneous lowering brought out of the profile and put back in again by exciting the magnets Braking position can be returned.

Claims

In order to achieve the lowest possible efficiency, the Wheels of the passing railroad cars from the brake rails as high as possible collected. The upper limit is given by the prescribed clearance profile. There this is higher for wagons than for locomotives, track brakes are used in shunting operations not easily drivable for locomotives. So far these have been used for locomotive journeys lowered, i.e. made profile-free. However, this requires a large number of movable ones Parts that are subject to heavy wear. The essence of the invention

■ 5 stands in the training of facilities that achieve the freedom of profile for locomotives in a simpler way. A specially shaped hard steel rail / is used for this purpose. This carries cast-on roller mills k, on which, with the intermediation of cast-on rollers / a second rail m, can be folded down for braking, in order to put the wheels on the rails; to run (Fig. i).

»5 Freedom of the profile can be achieved even more easily if you move the disruptive brake rails yourself out of the blocked space, e.g. B. Fig. 2 shows. In the braking state, the brake rails rest on loose leg plates and are carried by them in a pendulum manner. By shifting the center of gravity, the brake rails have η after

Releasing a lock the effort, which can still be supported by spring pressure, to swing outward on the standing metal sheets until the roller surfaces ο and ρ on the rail «and on the handlebar qii come into play. The movement is precisely dictated by the slot guide in which the rollers run. The end position is then the one shown in dash-dotted lines. If the brake is to be brought back into the braking position, this is done by switching on the magnet excitation. The stray flux thus created attracts each other and raises them up again with the help of the handlebars qii and guides r .
