Title
(EN) SWITCH MACHINE
(FR) MECANISME DE MAN×UVRE D'UN AIGUILLAGE
Abstract
(EN)
There is provided a switch machine (10) for controlling the position of railroad tracks having up to five improved capabilities. First, the switch machine (10) is designed to have a low vertical profile without increasing its axial length or sacrificing its functionality. Second, the switch machine (10) has a rail point detection and indication mechanism (210) that identifies a latch out condition when the railroad tracks are not at, or near, their proper positions before or after switching the railroad tracks. Third, the switch machine (10) has a trailing device (416) coupled to a throw bar (412) for enabling throwing of the switch points. Fourth, a cam bar (530) of the switch machine (10) locks and unlocks a lock bar (520) as required for railway track systems. Finally, an improved hand throw mechanism (730) of the switch machine (10) has a ratchet mechanism (740) that permits torque to be applied to the hand throw mechanism (730) in either a clockwise or counter-clockwise direction.

Mécanisme (10) de man÷uvre d'un aiguillage offrant cinq améliorations: (1) le mécanisme de man÷uvre (10) présente une faible hauteur sans augmentation de sa longueur axiale ni sacrifice de son efficacité; (2) le mécanisme de man÷uvre (10) possède un dispositif (210) de détection et d'indication de la position de l'aiguillage qui identifie l'état de déverrouillage lorsque les rails n'occupent pas la position voulue ou ne s'en approchent pas avant ou après leur man÷uvre; (3) le mécanisme de man÷uvre (10) possède un dispositif de talon (416) couplé à une barre de man÷uvre (412) commandant l'aiguille; (4) le mécanisme de man÷uvre (10) est muni d'une barre à came (530) qui bloque et débloque la barre de verrouillage (520) comme l'exigent les appareils de voie; (5) le mécanisme de man÷uvre comporte une commande manuelle (730) munie d'un mécanisme à cliquet (740) permettant d'appliquer un couple à la commande manuelle (730) dans le sens des aiguilles d'une montre ou dans le sens contraire à celui des aiguilles d'une montre.
