2 Claims.

This invention relates to window regulators but more particularly to regulators for the windows of automobiles and an object is to produce a new and improved power operated regulator mechanism for opening and closing-the window of a vehicle.

Another object is to produce a regulator mechanism for the window of an automobile door embodying a motor for operating the mechanism, the latter employing a swinging arm and a motor driven screw connected to swing the arm for efiecting the opening and closing movements of the window.

Other objects and advantages of the invention w ll hereinafter appear and for purposes of illustration but not of limitation, embodiments of the invention are shown in the accompanying drawings in which:

Figure 1 is a side elevation of an automobile door, a part of which is broken away to show the regulator mechanism for raising and lowering the window glass;

Figure 2 is an enlarged sectional view substantially on the line 22 of Figure 1;

Figure 3 is an enlarged side elevation partly in section, of the motor, the motor supporting posite or lower end of the arm l8 has a stud 22 which is slidable in a horizontal guide slot 23. As shown, the arm It! has a disc-like enlargement 24 centrally thereof in which is an openin 25. A disc 28 covers a portion of the opening 25 and is connected to the adjacent portion of the arm by a reduced neck. As shown in Figure'2, the arms I3 and are offset so that the arm 20 can project through the opening in the enlargement 24, and also so that the major portions of the arms lie in substantially parallel planes.

interposed between the arms l8 and 20 in the region of the disc 26 is a member 21 which in this instance is annular in form and is provided. with oppositely extending trunnions 28 which project through openings formed in the disc 26 and the adjacent portion of the arm 20. Cotter pins 29 extend through the trunnions 28 on the. outside of the arms for holding the member 21 in position and militatingv against the arms l8 and 20 becoming laterally displaced. The annular member 21 is provided with a vertically disposed screw-threaded opening 30 threadedly to receive bra k t. the operating shaft and the driving connections; and c Figure 4 is a side elevation of another form of motor supporting bracket in which the regulator J operating shaft constitutes the motor shaft.

The illustrated embodiment of the invention comprises an automobile door It! provided with-a window opening it having a window glass l2 which is slidable up and down to cover and uncover the window opening ll Beneath the opening it is a well into which the window is adapted to be lowered, guide channels l3 on opposite sides guiding the vertical movements of the window glass l2. In advance of the window glass 12 is a triangular shaped window glass M, which is of the usual type mounted on up and down pivots to enable the same tobe rocked to and from a position for deflecting air to the inside of the vehicle.

Embracing the lower edge of the window glass 13 is a channel l5 from which. horizontally slotted retainers l6 depend. The retainers I 6 are spaced laterally from each other in the usual manner and slidable in the slot of the left hand retainer is a stud I? mounted on the outer end of an arm l8. Slidable in the horizontal slot of the right-hand retainer i6 is a stud l9 mounted on the outer end of an arm 20. The opposite end of the arm 20 has a fixed pivotal mounting 2| and the opposed operating shaft 32.

the screw-threaded portion 3! of a vertically disthat upon turning movement of the shaft 32 in one direction, the arms I8 and 20 will be swung in such manner as to impart upward movement to the window glass 12 and turning movement in the opposite direction will cause the arms to impart downward movement to the window glass.

The lower end of the operating shaft 32 extends through an opening in a platform or bracket 33 which has a flange 33. A transverse pivot 35 is provided for the'fiange 34 to enable the bracket 33 to rock, thereby to compensate for tilting of the operating shaft 32 due to the swinging movement of the regulator arms. The lower end of the shaft 32 has a reduced neck 36 to receive a retaining washer 3'! disposed on the underside of the platform 33. Retaining member 31a on the shaft 32 above the platform 33 cooperates with the washer 31 in preventing endwise movement of the shaft.

An upright support 38 is carried by the bracket 33 and has a base portion 39 which provides a bearing for the shaft 32. Also carried by the support 38 are spaced uprights 40 providing bearings for the motor shaft 3|. Between the uprights 40 and carried by the motor shaft 41 is a worm 42 which meshes with a worm wheel 43 secured to the operating shaft 32. The motor shaft M forms a part of a reversible electric motor 44 which is suitably secured to the bracket platform 33.

It will be apparent- From the above description it will be apparent that'the electric motor 44 may be driven in one direction or the other to turn the shaft 32 in the desired direction through the worm 42- and worm wheel 43 thereby to effect window opening or closing movements as desired. It will be understood that all of the mechanism is contained within the door In, merely the wiring for operating the motor 44 leading from the door to a suitable operating switch which may be arranged in any convenient location.

In the form shown on Figure 4, the operating shaft 32a which contains a screw-threaded portion provides the armature shaft for the electric motor 44a which is suitably clamped to a bracket 33a. The bracket 33a is mounted on a pivot 35a for lateral rocking movements to afford tilting movements of the operating shaft 32a due to the swinging movement of the regulator arms as above described. Preferably the motor 44a should be a slow speed motor and of the reversible type in order to turn the operating shaft in one direction or the other as desired.

The above described regulator mechanism lends itself particularly for use in operating the windows of automobiles where cross-arm regulators are used to a large extent at the present time. Thus to adapt the mechanism now in use for a power driven regulator, the same may be readily and inexpensively accomplished. The electric motors employed are relatively small and inexpensive but have sufficient power for the purpose intended. This mechanism enables the entire automobile body to be equipped with power driven regulators at a, relatively low cost and in a relatively simple manner.

It is to be understood that numerous changes in details of construction, arrangement and operation may be efiected without departing from the spirit of the invention especially as defined in the appended claims.

What I claim is:

1. In a regulator mechanism for a window glass guided for up and down sliding movements to cover and uncover a window opening, an arm pivotally mounted at one end and having its opposite end in horizontal sliding engagement with the lower edge portion of the window glass, 9. second arm in cross relation to said first arm and having one end in horizontal sliding engagement with the lower edge portion of the window glass and its opposite end mounted for horizontal sliding movement, one arm being apertured adjacent its central portion and the other arm extending through such aperture. both arms being offset to enable the major portions of the length thereof to lie in parallel relation, a disclike member interposed between said arms at substantially the center thereof, a trunnion on opposite sides of said member engaging in the respective arm for rocking movements about an axis at substantially right angles to the line of movement of the window glass, said member having a vertically disposed screw threaded opening, a shaft extending through said opening and having screw threads engaging the screw threads thereof, means to anchor the lower end of said shaft, and motor driven means for turning said shaft in one direction or the other.
