Relates to vehicle window regulating mechanism of the kind in which a flexible driving element 19 Fig. 1 comprising a wire core 19a with a helically coiled wire 19b wound on the core, is guided in a tube 21 and is actuated by means including a rotable pinion engaging the wire 19b, the tube 21 and a actuating means being secured to a vehicle door and a connecting piece 20 projecting through a longitudinal slot in the tube 21 and secured to the element 19 connecting it to the window 10 which is slidably mounted on the door 11, so that operation of the actuating means effects movement of the window. According to the invention the connecting piece 20 is connected to a support member 17 supporting the lower edge of the window 10 and guiding elements e.g. rollers 28, 29, 30 are mounted on the support member 17 to engage the guide tube 21 so as to prevent angular movement of the support member 17 relative to the adjacent guide tube 21. As shown in Fig. 1 the support member 17 is connected to a window-edge support 13 by means of channels 14 so as to permit relative movement therebetween in a direction transverse to the length of the guide 21 and the support member 17 is connected to the driving element 19 by a resilient coupling comprising a pair of rubber pads 22 secured between brackets 23 on the piece 17 and the connecting piece 20 secured to the driving element 19. The roller 30 and one or other of the rollers 28, 29 may be adjustably mounted on the piece 17. The pinion engaging the wire 19b may be manually rotated or, as shown, operated by an electric motor 25. In a modification for operating a part cylindrical window panel 36 Fig. 5, movable in a vertical direction, the panel is rigidly mounted in a channel 37 on a plate 38 bolted to the window support member 39 and the rollers 28, 29, 30 thereon engage a reinforcing web 35 Fig. 7, formed on the guide tube 21, the peripheries of the rollers being correspondingly shaped to engage the curved ends of the web 35 and the rollers being mounted on part spherical bearing pieces 40, Fig. 6 (not shown) to permit them to align themselves with the web 35.

The height of filled bags B, advanced by dogs 4, 5 on a conveyer 3, is adjusted when the bags are placed on vertically adjustable support plates 8, carried on a conveyor 9, so that the height at which the upper surface of the bag contents enters a closing device 26 is kept constant. In the machine shown, the plates 8 are raised by a cam-controlled spring-biased lever 23 until the top of the bag contents, compacted by a vibratory support rail 6, engages a plunger 20 lowered by a pre-set height in the bag. This adjustment of the plates 8 is then maintained by a pawl-and-ratchet device (Fig. 3, not shown) which is released by a fixed cam surface 27 before the closed bag is removed from the intermittently advanced conveyer. The plates 8 are held in their lowest position during their return run by a rail 29 which contacts rollers 28 on rods 12 carrying the plates. The plunger 20 may move along with the bag while the height adjustment is being made. In other embodiments, two or more plungers are provided on a reciprocating rod to adjust the heights of two or more bags at once, and in this case the plates 8 are raised by vertically movable spring-loaded members acting against the rollers 28.
