[Class 20 (iii)] The top edge of a sliding window, particularly for vehicles, is fitted with a central nut engaged by a bodily-stationary flexible rod extending vertically across the window space. As shown, the nut 5 is secured to a channel 6 on the top edge of the movable panel 2 of a half-drop window the flexible rod 4 having its lower end secured in a bracket 7 on a channel forming a guard-rail at the top of the fixed panel 1. The upper end of the rod 4 is mounted in a box 8 secured to the top frame member and fitted with bevel-gears and an operating-handle 9. In a modification, the operating-gear is shown fitted at the lower end of a rod. According to other modifications (not shown), the operating- handle may be arranged at a remote point, the rod 4 being extended and guided (if necessary) around rollers : the nut 5 may be fitted inside a casing and formed with external teeth to mesh with a pinion actuated by the operating handle, in which case the rod 4 would be non-rotatably mounted in plain brackets; means may be provided to enable the window to be quickly adjusted from inside or outside the vehicle; e.g., a split nut may be used which is normally closed to engage the thread on the rod but is opened when direct upward pressure is applied to the window.
