Patent

CA 2205850

A coupler for use in replacing a corroded coupler on a buried water main valve without extensive soil excavation is disclosed. A pole having a cotter pin removal tool is provided to remove the cotter pin holding a corroded coupler in place about the valve. A rod having a fastener mounted on its lower end is releasably attachable to the water main valve. The rod carries a sleeve which slidably carries a latching device which is movable from an upper position in which the fastener carried by the rod is mountable on the water main valve, and a lower position in which the fastener is locked in position, allowing the valve to be rotated. The latching device carries a fastener mateable to a fastener carried by the pole, which allows the latching device to be moved between the upper and lower positions.

Cette invention concerne une tige permettant de remplacer la clé de manoeuvre rouillée d'un robinet d'arrêt enterré sans avoir à creuser autant qu'auparavant. L'objet de l'invention comprend une tige équipée d'un arrache-goupille servant à enlever la goupille fendue qui tient la vieille clé de manoeuvre en place sur le robinet et une barre comportant à son extrémité inférieure un dispositif de serrage pouvant être monté de façon amovible sur le robinet d'arrêt. Cette barre porte un manchon dans lequel coulisse un dispositif de verrouillage entre une position haute où le dispositif de serrage peut être monté sur le robinet et une position basse où ce dispositif est verrouillé en place pour permettre la rotation du robinet. Le dispositif de verrouillage comporte un élément qui peut se coupler au dispositif de serrage équipant la tige susmentionnée pour permettre son déplacement entre ses positions haute et basse.
