Abstract
An improvement in the car-side-window mechanisms of the cable-actuated type is disclosed, in which a device is provided which allows for the tension differentials which may occur in the actuating cable sections due to the uneven abutment of the window glass top edge against the window frame. The device is a takeup mechanism composed by an arcuate spring the ends of which coact with two swingable plates, each of which carries a follower. The plates under the bias of the spring can be approached to one another or diverge from one another and thus make up the tension differential in the two confronting cable sections, as transferred to such plates by the respective followers.
Claims4
A cable-actuated car-side-window lifting mechanism in which the lifting or depressional motion of the window glass plate is carried out by the rotation of a pulley around which there are wound and unwound two portions of the cable fastened to the bottom edge of the plate glass, characterized in that, in combination with said pulley two idle rollers are provided which are confrontingly mounted and about which said two cable sections are partially wound, said two rollers being mounted by the agency of supporting members for being rotated about the axis of the pulley in unison freely and discretly against the bias of counteracting means.
