Abstract: 518,449. Vehicle windows. MARVEL EQUIPMENT CORPORATION. Sept. 29, 1938, No. 28342. Convention date, Sept. 30, 1937. [Class 20 (iii)] A vehicle window panel 12 is guided for vertical sliding movement in a frame including an opening and a well below the same by means comprising a fixed upright guide channel 29 disposed within the well adjacent an upright edge of the panel, a metal channel 15 mounted on the lower edge of the panel, and a device mounted on one edge of the channel 15 and including an element 36 which, under the action of a spring 40, travels upon the outer edge portion of the guide channel at a distance from the base thereof and is movable bodily against the action of the spring relatively to and in a direction longitudinally of the channel 15. The panel 12 is shown in Fig. 1 as applied to a vehicle door including a sloping front pillar 10 and a rear pillar 11, being guided within the window opening by lined channel guides 28 which project just below the lower edge of the window opening. The lower edge of the panel is embraced by the lined channel 15 which is provided at each end with a welded anglebracket 31 provided with means for engaging an upright guide 29 arranged in the well. The guides 29 are arranged respectively beneath the forward and rear edges of the panel, being spaced inwardly from, and connected to, the lower parts 10a, 11a of the pillars 10, 11. Each guide 29 has a channel base, inwardly-converging portions 29d, and diverging portions 29c, as shown in Fig. 2. The depending flange 31b of each bracket 31 has riveted thereto the shank 32 of a stud 33 which fits between the converging portions 29d of the guide 29, and a cup-shaped washer 36 fits slidably over the shank 32 and main portion 33 of the stud with its convex or crowned face, making a two-point contact with the diverging portions 29c of the guide. A compression spring 40 fits between the rear of the convex face of the washer 36 and the anglebracket 31, and when the washer 36 is in contact with the guide there is sufficient clearance space 41 between the washer and the shoulder 35 of the stud to permit slight longitudinal sliding of the washer on the stud. As the panel is lowered, the front and lower edges thereof travel down through the mouths of the guides 29, but without making contact with any part thereof. If desired, the guides 29 may be located entirely outside the verticalpath of the edges of the panel 12. In the modification shown in Fig. 8, the guide 46 in the well is of general channel shape with diverging portions 46c for engagement by the washer 36. The panel 12 may be operated by a regulator of parallel-arm type comprising an angle member 18 having studs 17 which engage a pair of rails 16 welded below the channels 15; two parallel arms 21, 22 are pivoted between the member 18 and a mounting plate 23 on the door panel 42. A gear sector 26 which is driven from a pinion mounted on the handle shaft 27 is fastened to the pivot 25 of the arm 22 and also to the arm 22. Instead of two rails 16 on the channel 15, there may be a single rail having an aperture to permit the studs 17 to be engaged with the rail. The channel 15 on the lower edgÚ of the panel is of V cross-section except at its ends. The vehicle door comprises inner and outer pressed metal panels 42, 43 and a garnish moulding 44, the panel 12 being arranged to slide through a slot between the panel 43 and moulding 44 as shown in Fig. 4.
