Abstract

L'invention concerne un mécanisme d'entraînement supérieur de tête de puits composé d'un pignon menant, d'un pignon mené et d'un élément mobile. L'élément mobile comporte un premier pignon intermédiaire vers sa première extrémité et un deuxième pignon intermédiaire vers sa deuxième extrémité. L'élément mobile peut être déplacé d'une première position à une deuxième position, de sorte que dans la première position, le pignon menant entraîne le pignon mené par l'entremise du premier pignon intermédiaire, et, dans la deuxième position, le pignon menant entraîne le pignon mené par l'entremise du deuxième pignon intermédiaire.
