WINDOW-CONTROL MECHANISM.

Application filed May 9,

This invention relates to window control mechanism, and more particularly to mechanism for vertically adjusting windows of motor vehicles.

It is the object of the invention to provide a comparatively simple mechanism adapted to be enclosed within the lower portion of a vehicle door to actuate the vertical travel of a window member in the upper portion of the door ant serving to automatically maintain such window member in any desired position of adjustment.

A preferred embodiment of the invention is illustrated in the accompanying drawings wherein,

Figure 1 is a fragmentary inner side view of a motor vehicle door of the sliding window type, equipped with the herein described control mechanism and having a portion of the trimming broken away to disclose said mechanism. Fig. 2 is a vertical section of the door on the line 22 in Fig. 1. Fig. 8 is an inner side elevation of the control mechanism embodying the invention removed from the door. Fig. d is a section thereof on the line 14: in Fig. 3. Fig. 5 is a section on the line 5-5 in Fig. 3, and Fig. 6 is a perspective elevation of the swivel mounting for the screw stem of the mechanism.

Referring to the drawings, 1 designates a motor vehicle door and 2 a window opening in the upper portion of said door for which a closure is formed by a vertically slidable plate of glass 3, which, when lowered, enters the customary well or chamber 1- formed in the lower portion of the door. The door frame includes a crosspiece 5 disposed at the upper end of the well 1 at the inner side of the glass 3. A plate 6 is mounted on the outer side of the crosspiece 5 near one end thereof and covers an opening 7 provided through the cross-piece.

The actuating mechanism for the glass 3 comprises an arm 8 pivoted at one end to an offset tongue 9 projecting inwardly within the well 4 from the lower end of the plate, in the present instance, a distance below the lower edge of the crosspiece 5. The other end of the arm 8 carries a peripherally grooved roller 10 which engages a channeled sheet metal strip 11 secured to the bottom edge of the glass to support the glass and to travel lengthwise of said strip when the arm 1823. Serial No. 637,839.

is swung to raise or lower the glass. A nut 12 is swiveled upon the arm 8 adjacent its pivoted end and engaged by the lower threaded end portion of the upwardly extending stem 18, the upper portion of which is journaled in a mounting 1 1, which is sn'iveled in the plate 6 for swinging movements in a plane parallel thereto The swivel mounting 1 1, in the present instance, is of stamped sheet metal construction and is provided at its upper end with a pair of tongues 15 spaced longitudinally of the mounting and having axially aligned "bearings 16 for receiving the upper journal end of the screw stem 13. The lower end of the mounting 14 is provided with a laterally projecting tongue 17 from which a stud 18 rigidly projects upwardly through an enlarged opening 19 in the plate 6. The stud 18 is secured at its inner end within an open ing 20 in the tongue 17.

A small beveled pinion 21 is fixedly mounted on the screw stem 18 between the tongues 15 of the swivel mounting and is engaged and driven by a large bevel gear 22 which is journaled on the stud 18 and has its hub, projecting through and j ournaled in the opening 19 of the plate 6. A crank arm 23 is loosely mounted on the stud 18 without the hub of the gear 22 and is adapted to have keyed or interengaged connection with the gear hub to cause the gear and crank arm to turn in unison. A screw 24pis threaded into the outer end of the stud 18 and engages the hub end of the crank arm 23 to retain it in assembled position with respect to the gear 22. It is evident that a turning of the crank arm 23 will communicate a turning movement to the screw stem 13 through the interposed gearing and that the turning of the stem will effect a raising or lowering of the window supporting arm 8 due to the threading of the stem through the swivel nut 12 carried by the arm.

The weight of the glass on the arm 8 is counterbalanced, in the present instance, by one or more springs 25, which connect the arm 8 at a point near its inner end to a flange 26 struck inwardly from the upper end of the plate 6.

All the described mechanism, with the exception of the crank arm 23, is concealed within the well 4 of the door and carried as a unit by the plate 6 to facilitate assembling or removal of the same for repair or substitution. A portion of the described mechanism is disposed within the opening 7 of the cross-piece 5 so that the door or the well 4: therein does not need to be made of greater thickness than is customary in doors of this class in order to accommodate the glass controlling mechanism.

In the operation of the control mechanism, when it is desired to adjust the window member 3, the handle 23 is rotated in the desired direction. This rotation is transmitted through the gearing 22, 21 to the stem 13, which through engagement with the nut 12, effects the raising or lowering of the arm 8, according to the direction of rotation of the handle. As the nut is constrained to travel in a circular arc the stem 13 swings through a slight angle of the vertical, the divergence from the vertical being a maximum when the arm 8 is horizontal. The necessity for swivel mounting of the nut 12 on the arm 8 and for the swiveling of the member l l arises from this slight angular movement of the stem 13. It will be apparent that the engagement of the stem 13 with the nut 12 provides an automatic lock such as will serve to maintain any position to which the window member 8 may be adjusted.

We wish it understood that our invention is not limited to any specilic construction, fllltll1l;l11811t or form of the parts, as it is capable of embodiment in numerous i'orms without departing from the spirit of the claims.

hat we claim as our invention is:

1. The combination with a slidable window member, of a frame guiding the movements of said member, a plate secured to said frame and having an opening therein, a gear having a hub portion journaled in and projecting through the plate opening, a swivel mount carried by the gear for swivel movements coaXially therewith, an arm pivoted at one end to said plate and having supporting engagement at its other end with the window member, a swivel nut carried by the arm, a stem journaled in said swivel mount and threaded through the nut, driving connection between said gear and stem, and means for rotating the gear.

2. The combination with a slidable window member, of a frame guiding the movements of said member, a plate secured to said frame and having an opening therein, a gear having a hub portion journaled in and projecting through the plate openin a swivel mount carried by the gear for swivel movements coaxially therewith, an arm pivoted at one end to said plate and having supporting engagement at its other end with the window member, a swivel nut carried by the arm, a stem journaled in said swivel mount and threaded through the nut, driving connection between said gear and stem, means for rotating the gear, and counterbalancing means connected to said. arm.

3. The combination with a slidable win dow member, 01'. a frame guiding the movement of said member and including a recessed cross piece, a plate secured to said frame, an arm pivotally mounted upon said plate and operatively connected to said window member, a swivel nut carried by said arm, a stem threadedly engaging said nut, gearing upon said plate within the recess in said cross piece, said gearing being connected to said arm, and window counterbalancing means extending within the recess of said cross piece.

In testimony whereof we have hereunto signed our names to this specification.
