Patent

CA 2098856

An improved open end construction for jacks which provides for tabs which extend at right angles to the side surfaces of the channel members so as to allow pivot pins to be received in the open ends after which the tabs are bent so that they lie in the plane of the side surfaces of the channel members so as to lock the pivot pin in the ends of the channel assembly. Also, partial flanges can be formed about the openings in the ends of the channel members so as to provide bearing surfaces for the pivot pins.

Une amélioration est apportée à une terminaison ouverte pour un vérin. Cette terminaison est constituée par des languettes orientées à angle droit par rapport aux côtés des canaux, permettant d'insérer une cheville dans cette terminaison. la suite de cette opération, on replie les languettes de façon qu'elles soient orientées dans le plan des côtés des canaux, de sorte que la cheville soit immobilisée dans la terminaison. On peut également monter des anneaux partiels aux ouvertures des terminaisons des canaux afin de fournir des surfaces d'appui aux chevilles.
