Before explaining in detailthe present inVention it is to be `nnd'erstood that' the invention is l` not limited in'its `application to the details of construction and-arrangement of parts illustrated in the accompanying drawings, since the inven-A tion is capable of other embodiments and of being practiced or carried out in various ways. Also it is to be understoodl 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 5 beyond the requirements of the prior art.

There is shown in the drawings an automobile door 20 having a front pillar 2| in which is placed a glass runway channel 22. 'I'he door 20 is provided with a rear pillar 23 having a deep glass 10 runway channel 24 terminating at the window sill and thence provided with a shallow channel 24a extending below the window sill. A window glass 25 is provided and is adapted for slidable movement vertically in the channels 22, 24 and 15 24a, and horizontally into the deep channel 24. A channel-shaped retainer strip 26 is secured to the bottom of the glass 25. As shown in Figs. 3 and 4, the window regulator mechanism 21 may be installed at any suitable place in the door 20, 20 such for example as on the lock board, and is provided with a xed supporting plate 30. Rotatably mounted on the supporting plate 30 are meshed gears 3| and 32. A rotatable handle 33 is provided to actuate the regulator mechanism 25 .21 and is suitably attached to a driving pinion 34 meshed With a gear sector preferably punched from the same metal blank as the gear 32. In the present embodimentsof the invention the window regulator is shown by way of example 30 as of the two armtype and comprises a pair of swinging arms 31 and 40 for raising and lowering` the window, these arms carrying at their outer ends button devices or headed studs 42 and 43, respectively, which slide longitudinally in 35 channel ways formed in the retainer strip 26. The arm 40 also is provided with a lateral cam extension 4| constructed for the purposeof shifting lthe window horizontally and locking the window when the latter is in predetermined ele- 40 vated position. In one embodiment of my invention as shown in Figs. 3 and 4, the cam extension 4| is provided with a cam slot 44 and an extending finger 45. A plate 46 depends from the channel retainerV 45 26 and.is provided with a pin or stud v41 whichv is secured thereto at a position where it maybe engaged in the slot 44. AV curved cam surface-till' is formed on the extension 4| between the slot 44 and thestd 43.l l T50 In the embodiment of myfinvention shown in Figs. 1l and ;2 the'cam extension 4| isprovided' with an extending side or cam forming" edgev 5| adapted to engagefthe side of the pin 41 ffor retracting the glass. In this embodiment of my invention the contact of the cam edge 5| with the pin 41 is employed for the shifting of the glass 25 in one horizontal direction, whereas in the embodiment of my invention shown in Figs. 3 and 4 the opposite edges of the slot 44 engage successively the pin 41 to shift the window 25 in a forward as well as a rearward horizontal direction.

In the embodiment of my invention shown in Fig. 7 the cam 4| carries a pin or stud 53 which contacts successively with cam edges or surfaces 54a and 54b formed on a plate 54 secured to the glass retainer 26.

The glass retainer 26as shown in Fig. 6 is provided with a U-shaped glass receiving channel 55 forming the upper side of a runway 56 and having felt or similar glass engaging cushioning elements 51 secured therein. Secured to the U shaped glass receiving channel 55 is a member 58 forming the back and bottom portion of the runway. As here shown the runway 56 has a constricted front opening extending longitudinally of the channel 26 which is of less height than the diameter of the studs 42 and 43 thereby interlocking the latter against withdrawal during their normal sliding movement Within the runway 56. The member 58 is provided with a lower extending lip 59 which, as hereinafter described, provides a bearing portion. The member 58 may have a cut-away notched portion in the bottom thereof, as shown at 60 in Fig. 3, providing an opening through which the enlarged heads of the studs 42 and 43 are inserted vertically into the runway 56. A Variation of this construction is shown in Figs. 1, 2 and 6, wherein instead of the cut-away opening 60 the extending lip 59 is pressed to provide depressed notch portions 6| and 62 which are adapted to permit the installation of the heads of the studs 42 and 43 through the face of the member 58 in order to occupy their operative positions Within the runway 56. In this embodiment of my invention the back wall of member 58 is punched inwardly to provide a lug 63 which extends into the runway 56 and is contacted by the stud 43 to shift the window glass 25 horizontally in one direction.

The studs 42 and 43 as shown in Figs. 5 and 6, are each provided with an enlarged head 64 and a restricted neck 65, and are secured to the respective arms 31 or 40 by riveting or other suitable means. Mounted on the restricted neck portion 65 of each stud is a conical washer 66 which is yieldingly held in position by a spring 61. The conical washer engages correspondingly shaped flared bearing surfaces formed by the lip 59 and the outer lower side off the channel strip 55.

In the operation of the several embodiments it will be seen that the window glass 25 will be raised and lowered in a vertical direction as a result of the swinging movement ofthe regulator arms 31 and 40, these arms swinging toward and from each other in conventional manner and being operated by the gearing from the usual crank handle 33. During this operation the headed studs or buttons 42 and 43 travel longitric with the axis of swinging of arm 4| it will simply contact With the pin thus providing a supporting medium so that at this time the window will have a three-point support. At the same time the cam 50 while in engagement with pin 41 will lock the window glass against rearward sliding movement into the deep channel. Hence, as the window glass moves into elevated position opposite the deep channel 24, at which time its rear vertical edge will be unsupported, the window will be maintained against tilting movement and also against rearward sliding movement by virtue of the three-point support formed by studs 42 and 43 and cam 50 contacting with pin 41. When the window glass reaches its full elevated position the pin 41 moves into engagement with the upper end of cam face 5| and continued swinging movement of arm 4| will result in shifting the glass rearwardly into the deep channel by virtue of the engagement of stud 43 with the lug 63. During this operation pin 41 travels along the edge of cam 5| so that the window glass will be locked in any horizontally moved position except when the regulator arms are swung. It will be seen from Fig. 2 that when the arms are swung in the opposite direction the cam 5| will engage pin 41 and shift the window horizontally into closed position, and upon continued downward swinging movement of the arms the window will then be lowered.

'I'he operation of the embodiment shown in Fig. '1 substantially corresponds to that above described since in this instance certain of the operating parts are simply reversed. That is to say, the cam surface 54a, which is concentric with the axis of swinging of lthe arm 40, cooperates with the pin 53 and performs therewith the same function as the cam 50 and pin 41 of the previous embodiment. Moreover, the cam surface 54h in cooperation with the pin 53 performs the`same function as the cam 5| and pin 41 in eifecting a horizontal retraction of the window in its upper closed position.

In each of the preceding embodiments it will be seen that the notched portions 6| and 62 formed in the lower horizontal flanges of the runways provide lopenings of sufficient diameter to permit direct and simultaneous insertion of the button devices 42 and 43 into the runways when the window glass is being assembled with the regulator arms.

Referring to the embodiment illustrated in Figs. 3 and 4, in this instance as the regulator arm 40 is swung upwardly to move the glass vertically into closed position, the cam 50 will travel into contact with the pin 41 thus supporting the window glass and locking it against horizontal displacement into the deep channel, as in the previous embodiments. In this instance the opposite edges of the cam slot 44 provide the means for successively shifting the window horizontally in opposite directions, the forward edge of the cam slot performing the same function in moving the window into Ventilating .position as the lug 63 and stud 43 in the previous embodiment and the rear edge of the cam slot performing the same function as the cam 5I or 54h.

In assembling the regulator arms with the retainer strip 26 in the embodiment of Figs. 3 and 4, the arms are first moved into extreme upright positions whereby the studs 42 and 43 under-lie the cut-away opening 60 in the bottom of the runway. The window glass is then shifted downwardly and vertically until the studs lie opposite the inner ends of the runways and then the regulator arms are cranked so as to swing the arms apart and shift the studs horizontally into the runways. Since it is necessary during this operation to install the pin 41 in the cam slot 44, the outer edge of the extension 4| is formed with an embossed cam portion 4|a, see Fig. 3A. Thus, as the arm 40 is swung to the left in order to project the stud 43 into the runway, atthe same time the inclined cam portion 4|a will ride up over the end of pin 41 springing the cam extension 4| outwardly sufiiciently to permit travel of the pin 41 into the cam slot 44.

In the foregoing embodiment means is provided for limiting the downward movement of the window glass at its lowest position. This is accomplished in Figs. 3 and 4 by meansl of a projecting stop 80 on gear 3| which, as the arms swing downwardly to the lowest position, engages the lower edge of-the plate 30 and prevents fur-l ther movement of the window into the door well. If desired the lower limit of movement of the window glass may be determined by means of rubber bumpersv8| and 82 mounted in the lower ends of the glass runways and in position to be engaged by the glass.
