CA 2165835

A switch for connecting a railway track (1, 1) with a branch railway track (2) the railway track having a discontinuity, switching being effected by a mechanism which moves both ends of the railway track adjacent the discontinuity from a first position in which they align with both ends of a fixed part of the railway track (5, 6) to a second position in which they align with both ends of the branch railway track (7, 8), the movement being effected by causing a section of the railway track (3, 4) adjacent to the discontinuity to flex. In a preferred form of the invention the section of the railway track is lifted and lowered during the switching procedure. The two rails (3, 4) of the flexing section are connected together by ties (20), these ties (20) when moved cause the rails (3, 4) to flex.

L'invention concerne un aiguillage reliant un rail de voie ferrée (1, 1) avec un rail de voie ferrée (2) de ramification. Le rail a une discontinuité, et l'aiguillage est assuré par un mécanisme qui déplace les deux extrémités du rail jouxtant la discontinuité entre une première position dans laquelle elles s'alignent sur les deux extrémités d'une partie fixe du rail (5, 6), et une seconde position dans laquelle elles s'alignent sur les deux extrémités du rail de ramification (7, 8), le mouvement étant effectué en provoquant la flexion de la section du rail (3, 4) jouxtant la discontinuité. Dans une forme d'exécution préférée de l'invention, la section de rail est soulevée et abaissée durant l'opération d'aiguillage. Les deux rails (3, 4) de la section de flexion sont reliées ensemble par des traverses (20). Ces traverses (20), lorsqu'elles sont déplacées, provoquent une flexion des rails (3, 4).
