PATENT LETTERING

-Λ * 201442-CLASS 20 &. GROUP

Patented in the German Empire on August 14, 1907.

• To limit the feeding areas of the catenary, as well as parts of the same when repairs are made To be able to separate from the rest of the catenary is known to be a subdivision provided, and that the colliding catenary ends can be guided one piece next to one another and during ironing operation be guyed upwards. To now the transition of the bracket of passing vehicles To make moving from one wire to the other as easy as possible is apparently the simplest means of keeping both wires in one place . isolated from each other at "the same height. To this, however, one is proportionate Heavy arrangement required, which causes the bar to fire when the Vox glides over quickly this point does not exclude.

According to the invention, a more favorable arrangement is achieved in that the from the Stirrup grinding level upward tensioned contact line ends on two or more flexible stored points are pressed down so that both overhead lines at the intersection have an obtuse angle as possible form with each other.

With the one shown in the drawing

Embodiment of the invention is

- It has been assumed that the overhead line according to the one described in the patent 164565 Way is hung.

i, 2 are the 'to be isolated from each other Contact wires, 3, 4 the hoist wires, 5, 6 the suspension cables and 7, 8 those with the outriggers 9, 10 provided masts. The supporting ropes are on the booms by means of the brackets 11, 12 5, 6 stored; Furthermore, the cantilever wires 3, 4 are braced insulated on the booms.

The contact wires are on the auxiliary support wires * 3, 4 and between the masts 7, 8 suspended from the tubular metal brackets 13, 14 by means of the eyelets 15 to 18 and 19 to 22, respectively. Of the latter, the eyelets are 15, 18, 19 and 22 directly under the support wires 3, 4 or under the brackets 13, 14 closed carried out so that they run the contact wire against the upward tension of the bracing of the contact wire ends and push it down at the crossing point in almost the Hold the rails in a parallel position (measured in the vertical longitudinal section). The eyelets 18, 19 support themselves here by means of rollers from below against the bracket 13, 14 to make it easier to move to enable; Furthermore, with their upper extensions, they comprise the suspension cables 5, 6 in the form of a fork in order to avoid lateral movement of the contact wire as a result of the upward tensioning tension and the wind pressure to prevent. The tensioning of the contact wire ends is done automatically in the present case by means of weights with the interposition of of the chains 27, 28 guided over the rollers 23 to 26. The ones attached between the contact wire ends and the chains Insulators can be displaced on the flat iron rails by means of the rollers 29, 30 31, 32 stored.

The tubular brackets 13, 14 are expediently provided

before installation a deflection upwards so that they. only as a result of their own weight and the weight of the catenary assume a straight position.

It is also essential in the embodiment that the auxiliary support wires 3, 4 to the Outriggers 9, 10 are guyed in front of the crossing point, as in this way a large one Air gap between the boom and the current-carrying wires (contact lines) is achieved. A lifting of the latter by a pantograph with overly tensioned Contact springs to the boom and the creation of short circuits as a result therefore prevented.
