Abstract

A.APPAREILLAGE A BALAI, NOTAMMENT POUR MOTEURS A COURANT CONTINU. B.IL COMPREND UN BALAI, UN PREMIER ET UN SECOND CONTACTEURS ET UN MOYEN DE SOLLICITATION; LES CONTACTEURS SE DEPLACENT ENTRE UNE POSITION OUVERTE ET UNE POSITION FERMEE EN REPONSE A L'USURE DU BALAI. LE MOYEN DE SOLLICITATION POUSSE LE BALAI DANS UNE DIRECTION PRESELECTIONNEE ET DEPLACE DE FACON CONTROLABLE CELUI QUE L'ON A CHOISI DU PREMIER OU DU SECOND CONTACTEUR EN REPONSE A L'USURE DU BALAI. LE BALAI EST LIBRE DE SE DEPLACER DANS LA DIRECTION PRESELECTIONNEE EN REPONSE A L'USURE DU BALAI. C.MOTEURS ELECTRIQUES.A. BRUSH EQUIPMENT, ESPECIALLY FOR DIRECT CURRENT MOTORS. B. IT INCLUDES A BROOM, A FIRST AND A SECOND CONTACTOR AND A MEANS OF SOLICITATION; THE CONTACTORS MOVE BETWEEN AN OPEN AND A CLOSED POSITION IN RESPONSE TO BRUSH WEAR. THE MEANS OF STRESSING PUSHES THE BRUSH IN A PRESELECTED DIRECTION AND MOVES IN A CONTROLLABLE WAY THE ONE CHOSEN FROM THE FIRST OR SECOND CONTACTOR IN RESPONSE TO THE WEAR OF THE BRUSH. THE BRUSH IS FREE TO MOVE IN THE PRESELECTED DIRECTION IN RESPECT OF THE BRUSH WEAR. C. ELECTRIC MOTORS.
