19 Claims.

This invention relates to devices for guiding and controlling glass or transparent panels of windows, particularly windows of automobiles in which the transparent panels or panes are adapted to be raised and lowered, usually through the medium of some suitable window regulator mechanism operable from the inside of the automobile body. l

In accordance with conventional automobile body construction the door or. other sidewall portion of the body is provided with a window opening adapted to be closed or partially so by means of a glass panel which may be lowered into a well below the window opening. In conventional practice the front and rear upright edges of the glass panel are guided within the well by means of channels lined with felt or equivalent material which receive and embrace the edges of the glass. To provide proper guiding of the glass within the window well and also to prevent rattling of the glass when partly or fully lowered it is, necessary inv practice to provide a relatively snug fit of the edge of the glass in the felt or otherwise lined channel. Owing to allowable tolerances inproduction and manufacturing variations or inaccuracies it has been dilcult to secure uniformly theA desired `rlt of the edges of the glass within the guide channels. If the glass fits too tightly excessive friction is set up rendering it more difficult to raise and lower the glass and placing undue strain on the regulator mechanism, and e Athis condition occurs frequently in productiongrtlhasbeen necessary to make the window regulators stronger than need be, thereby increasingv their cost. Sincey these felt lined channels, mounted in the window well, are exposed to the weather and become wet as a result of water running down the edges of the window opening into the channels duringv rainy weather or when the car is washed, even greater effort is required under such conditionsto operate the window.

It will thus be seen that an accurate sliding fit of the glass within the guide channels is extremely diicult to obtain owing to variations due not only to manufacturing conditions but also to the wet or dry condition of the channel linings.- Moreover, such lined guide channels yare relatively expensive not only from a manufacturing standpoint but also from the standpoint of increased labor expense due to difficulties in installing the glass therein on the assembly line.

' relatively simple in construction, capable of efvariations without appreciably increasing the efvlower edge of the glass or window panel, such fecting substantial savings in material and labor costs, and more eincient in use. a

A further object is to providev an improved window glass guide which eliminates the necessity of directly guiding the upright edge of the glass into and out of the window well, which provides more accurate control of the glass regardless of manufacturing variations, and which automatically accommodates or compensates for such fort required to move the glass up and down.

Another object is to provide guiding means at, but independent of, the opposite upright edges of l the glass which permits and also takes up slight end play, i, e. edgewise movements of the glass in its plane, frequently caused by the throw of the window regulator or resulting from small inaccuracies in the window regulator construction.

Still another object of the invention is to provide an improved window glass guide permitting .easy and economical installation of the glass, provlding easier operation of the glass and, as a consequence, permitting the use of windowregulators of less rugged and, therefore, less expensive construction. 4

Another object of the invention is to provide improved guide mechanism within the window Well of a vehicle body, which mechanism preferably includes a channel member for retaining the 30 channel member, which may be in'one or more "sections, having guiding means, such as devices on the bottom thereof, adapted to travel up and down upon fixed guides in the window well, yielding means being associated with the guiding means to assist in holding the glass in proper lposition while at the same time permitting slight in a direction transverse to the plane of the panel.

A further and more specic object of the invention is to provide improved guide mechanism within the window well of a vehicle body includ- 45 ing a glass retainer channel for the lower edge ol the window glass having a projecting guide member or members on the bottom of the channel cooperable with a fixed upright guide or guides within the window well, 'the guide member pref- 50 erably embodying a device, such as a stud and a spring pressed compression member slidable thereon, extending longitudinally of the vehicle body and yieldable in a longitudinal direction under the inuence of its spring. The guide 55 mechanism further preferably includes a :Ixed upright channel guide or guides 'within the window well upon which the guide device or devices are adapted to travel, the construction and arrangement being such that the upright edge of the glass during operation will lnot contact the channel guide and the cooperation of the guide Adevice and channel guide being such that movement or displacement of the glass in a direction transverse to the plane of the panel is resisted.

Theabove and other objects of the invention will appear from the followingI description and V`appended claims when considered in connection with the accompanying drawings forming a part of this specification.

Before explaining in detail the present invention it is to be understood that the invention is not limited in its application tothe details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also it is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation, and it is not intended to limit the invention claimed herein beyond the requirements of the prior art.

In the drawings there are illustrated certain embodiments of the invention applied, by way of example, to an automobile door. It will be understood, however, that the invention is not so limited and that the embodiments thereof are susceptible to changes and other applications and may be utilized in other relations. In Fig. 1 there is illustrated an automobile door A which may be a front door including a sloping front pillar Ill and a rear vertical pillar Il, the upper portion oi.' the door being provided with a main window opening adapted to be closed by means of a vertically sldable glass or other transparent panel i2. It will be understood that the term glass assess? is used herein in a generic, sense and is intended to comprehend any panel regardless of material movable up and down to close or open a. window opening. Secured to the lower edge of the window glass panel i2 is what is herein termed a glass retainer member or bar i5 which comprises a rolled channel member having a liner of felt or other material embracing the lower edge of the glass and secured thereto. To the back side of the channel member or bar I5 is spot welded a pair of longitudinally spaced rolled metal rail sections i6 which are spaced apart at lia between their inner ends to permit assembly of the window regulator. These sections i6, if desired, may be made in one length with a notch or aperture through the bottom thereof corresponding to the space lia to permit passage of one of the regulator studs l1 when the window glass is lowered into the window frame and assembled with the regulator in the extreme lowered position of the latter. The rail sections I6 are formed to provide longitudinal guideways for the headed studs, rollers or the like I1 carried at the outer end of the window regulator, the studs travelling or sliding in the guideways of sections i8 when the window is raised and lowered.

Any suitable window regulator may be utilized and in the present instance a regulator of the parallel arm type is shown for the purpose of providing through the medium of the spaced projecting studs i1 a support for the window panel i 2 at two horizontally spaced points. A single arm regulator or other type of two arm regulator may be used if desired. The illustrated regulator comprises a horizontal bar i8 to which the studs i1 are secured as by riveting, this bar having a `depending angular extension Ia. Pivoted at vertically spaced points I9 and 20 to the angle bar i8 are a pair of parallel swinging arms 2i and 22, the inner ends of which are pivoted to a mounting plate 23 at-vertically spaced points 24 and 25 corresponding to the spacing of the pivots i9 and 20, the mounting plate being secured by screws to the inner door panel 42. A gear sector 26 is fastened to the pivot 125 and hence to the arm 22 for swinging the same and this sector is driven through the medium of a pinion mounted on the handle shaft 21. The sector 2G has a central opening 26a within which the pivot 24 is located and is riveted also at point 26h to the driving arm 22, Upon turning the handle shaft 21 through the medium of a handleat the inner side of the doorthe 'gear 26 will be rotated and the arms 2| and 22 will be swung in parallel relation to raise and lower the window i2.

'I'he rear upright edge i2a' and front upright edge |2b of the glass panel i2 may be guided within the window opening through the medium of felted or otherwise lined channels 28 which are designed to embrace the edges of the glass and seal theopening when the glass is fully raised. These channel guides 28 terminate at or slightly below the lower edge of the window opening as indicated at 22a. Within the well below the window opening thewindow glass I2 is guided in its up and down path of movement substantially entirely through guiding means which is operative independently of the edges i2a and I2b of the glass. For this purpose there right or vertically extending ixed guide me'mbers 29, one substantially beneath the forward upright edge oi' the glass and the other substantially beneath the rear edge thereof. In the Y is mounted within the window well a pair of upembodiment illustrated in Figs. l to 7 inclusive the fixed upright guide members 29 are arranged substantially in vertical alinement with the edges |2a and I2b of the glass panel. Each guide 29 may be Yspaced inwardly from the base Illa or I la of the pillar I or pillar Il and supported therefrom through the medium of angle brackets 30 spot welded to the pillar and to the guide chan-l nels 29. The glass retainer member or bar I5, one embodiment of which is illustrated in Fig. 7, is provided at opposite ends with projecting guide members adapted to cooperate with the vertical guides 29. The channel I is ordinarily rolled in the form of a V-shape along the base thereof. At opposite ends, however, the base of the channel I5 is formedflat as illustrated-in Figs. 4 and 5, and spot welded to each of these flattened portions is" the horizontal flange 3Ia of an angle bracket 3l, see Figs. 4 and 5. The angle bracket 3l is located at each end of the retainer member I5 and has a depending ange 3Ib to which is riveted at 32a a shank 32 of a stud 33, the shank of the stud being reduced at 34 (see Fig. 2) and headed over at 32a, there being an annular shoulder 35 between the shank 32 and the cylindrical end or headed portion 33 of the stud. Mounted on the stud 33 is a compression member in the form of a cup-shaped washer 35,

see Fig. 6. This washer preferably has a convex semi-spherical or crowned contact face 31 pressed centrally to provide an inwardly extending cupshaped recess 38. The cylindrical or annular side wall 38a of this recess fits over the head 33 of the stud and has a sliding flt thereon.Y The wall 38a terminates in an inwardly extending flange 39 apertured to fit freely over the shank 32. The crowned'face of the member36 forms an annular recess at the back thereof to receive and retain one end of a compression spring 40. the opposite end of the spring bearing against the flange 3Ib.

' Each guide member 29 is in the form of a channel having ai base 29a. and parallel side walls terminating in inwardly converging portions 29h. The guide members 29 are preferably in the form of rolled sections and converging portions 29h terminate in constricted neck portions 29d, the metal thence being bent outwardly to provide diverging track portions 29c. When the window is installed the heads 33 preferably have a sliding t in two directions against the constricted neck portions 298, i. e. vertically and longitudinally. The crowned faces of the washers 36 contact the flaring or diverging portions 29e of theguides and at this time the springs 40 are under compression thereby spacing the anges 39 from the shoulders 35 of the heads of the studs as shown at 4I (Fig. 2). Sufficient clearance space 4I is normally provided so as 'to permit slight longitudinal sliding of the washer on the stud during operation of the window to compensate for slightl variations in the vertical guides and in thespacing apart thereof.

In conventionalconstruction the door or body is provided with an in ner pressed metal panel 42 andan outer pressed metal panel 43, the panel 42 supporting a garnish molding 44 which extends around the window reveal. Between the upper downwardly flanged edges of the garnish molding 44 and outer panel 43 is a longitudinal slot along the lower edge of the window opening through which the glass slides, and below the window opening between the outer and linner panels is the window well 45 within which the guides 29 are located. i

In Figs. 8 and 9 there are illustrated some modifications in the above described 'embodiment. In this instance the guide channel 29 is replaced by means of a channel 46 which may be secured and located in the same manner through the medium of the angle brackets 30. Each channel 46 has a bottom wall 46h and parallel side walls 46a which terminate in outer flared track portions 46c. There maybe mounted upon the' stud 33,v a compression member or cup-shaped washer 36 which is similar to the washer of the previous embodiment except that it is preferably die cast instead of 4pressed sheet metal. The construction of the washer, stud, spring and the mounting thereof is the saine as above described. The crowned face of the washer slidingly engages the outer flared or tapered portions 46c of the channel. In this instance the channelway in member 461s somewhat wider than the channelway in the member 29 due to the omission of the constricted neck 29d and hence the head of the stud 33 is spaced from and does not engage the side walls 46a, the entire engagement ofthe guide being accomplished through the washer 36 and flared contact surfaces 46c.

In practice the glass retainer member, such as illustrated in Fig. '1, is secured to the lower edge of the glass panel I2. This structure can then be readily assembled within the door or body by passing the lower edge of the glasstogether with the glass retainer member through the slot at the lower edge of the window opening between the flange 42a of the vinner'door or body panel and the ange 43a of the outer panel. I'he edge 334 of the studs will pass into the upper open ends ofthe channel guides 29 or 46. At this'time when the crowned or convex faces of the washers 36 engage the upper end edges of the chan-- nel guides the .washers will be forced back upon the Shanks 32 of the studs thereby placing the springs 40 under compression. 'I'he studs and washers will, therefore, readily travel into the upper ends of the channel guides into the position shown in Fig. 1. When the window glass is lowered by means of the window regulator it will be seen that the front and rear upright edges of the glass will travel down Vthrough the open mouths of the channel guides 29 or 46, see Figs. 3 and 9.' The edge of the glass will pass freely between theA side walls 46a or the cnstricted necks 29d of the channel without contact therewith.

Since the washers 36 preferably each have .a two-point contact with the guide, thewasher can yield slightly in any direction and will move in and out against the compression of the springs due to slight tilting or longitudinal movements' of the window glass in theplanev of the glass. By thus providing a guide device, such as stud 33 and compression member 36, having in effect a limited universal movement with respect `to guide 29 or 46 while yieldingly held against rattling or vibration by springs 40 which are constantly under compression, a very easily functioningguide is produced which has a relatively tight nt at all times, yetwill yield slightly as needed inlall directions, will not bind' or produce undue friction at any time under any condi-tions, and will permit easy and quick installation of the glass. It is preferredthat the clearance space between the outer end of the stud 33 and the base 29a or 46h of the channel guidel be slightly less than the clearance between the edge of the glass and the base of the channel, thereby preventing engagement of the glass with the bottom of the channel at any time. Due to the two point .con- 75x tact of each washer or compression member with the portion 29e or c very little friction` will be set up between the stud and washer devices and the vertical channel guides 29, and as the glass is lowered out of the upper channels 2l the amount of frictional resistance to the downward movement of the glass will gradually diminish. and in any case the total frictional resistance to I lthe operation of the window glass will be materially less than heretofore where it was necessary to provide felted or otherwise lined guides 2l extending the full distance of travel of the glass or substantially so.

Referring to the embodiment illustrated in Figs. 10 to 12 inclusive, it will be noted that the construction is substantially the same as that shown and described in the previous embodiment with the exception that the vertical guides 29 within the window well are located out of the vertical path of movement of the edges |2a and |2b of the panel I2. In'the previous embodiment the guides 29 are shown in such positions that the upright edges I2a and I2b of the window panel will pass down through the channelways in the members 29 but free of contact therewith. In the embodiment shown in Figs. 10 to 12 inclusive these upright edges of the glass do not pass down through the channelways in the guide members 29 but in spaced relation thereto. As illustrated in this embodiment the guides 29 are also mounted on the pillars as by means of angle brackets 30. The angles 3| secured to the opposite ends of the glass retainer channel I5, as well as the guide studs 33 which carry the spring pressed compression members 36 together with the vertical guides 29, are so arranged that the edge I2a or 12b of the glass will travel in the longitudinal plane of the guide 29 but in front or rear thereof without passing through the channelway in the guide. Thus, as shown particularly in Fig. 12, the upper glass runway or channel 28 within the window opening terminates at 28a as in the previous embodiment near the lower edge of the window opening but in this instance the guide 29 is offset with respect to the upper guide 2l so that the channelways in the two guides 2l and 29 extend out of vertical alinement.
