WINDOW REGULATOR.

L Application filed November 10, 1922. Serial No. 600,151.

To all whom t may conce/m:

Be it known that I, PAUL J. NELSON, a citizen of the United States, residing at Detroit, county of Vayne, State of Michigan, have invented a certain new and useful Improvement in Window Regulators, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to improvements in window regulators, particularly those which are used in connection with the slidably mounted windows of automobile closed bodies.

The object is to provide an improved connection between the window to be operated and the operating structure of the regulator, which connection is simple, durable and eflicient; substantially nois'eless in operation, and prevents rattle and unnecessary play between the window and the operating mechanism of the regulator while permitting the necessary free movement of the operating structure. Further, the connection is of such a character as to absorb or cushion the shock transmitted to the window by the operating mechanism of the regulator, particularly at the beginning of the movement of the window, and so transmits the motion from the operating parts of the regulator to the window as to insure free and easy travel of the window during its movement.

The above and other objects, together with the features of construction and operation will more fully appear from the following description, appended claims and accompanying drawing, in which:

Figure 1 is a side elevation of a portion of a closed vehicle body showing my regulator in association with a slidable window disposed in the body door.

Fig. 2 is a broken away side elevation showing the connection between the window and the operating mechanism.

Fig. 3 is a cross-sectional view taken on the line 3-3 of Fig. 2.

Fig. 4 is a cross-sectional view taken on the line 1 -4 of Fig. 2.

Fig. 5 is a perspective of a portion of the connection between the regulator and the window.

Fig. 6 is a side elevation of a window regulator provided with my improvement.

Fig. 7 is a perspective of a pair of gears in the train showing the lifting ribs.

My invention primarily relates to the connection between the window and the operating structure of the regulator rather than the regulator operating mechanism itself; which latter mechanism is described in the United States application of Orson G. Burch, Serial Number 57 0,609, filed J une 24:, 1922, and though my regulator is here shown in association with the slidable window of a closed body, obviously it might be used wherever desired.

The specific type of window-operating mechanism in connection with which I have shown my invention is that described in the pending application of Burch, above referred to. However, it is understood that my invention is not limited to windowoperating mechanism of this specific character. Briefly, this operating mechanism comprises a casing 13 within which is mounted a train of gears 12. These gears are driven by a pinion 20 which is actuated by a hand crank 111 that is conveniently disposed for manual operation interior the body. One side of the casing is out away to provide a sinn-ous guideway 13a.

Each gear is provided with a pair of radially-extending lifting ribs 21 which are adapted to align with the lifting ribs of the adjoining gear when in a certain position.

Mounted within the sinuous guideway 13a is a traveller which is adapted to be passed along from one gear to the other to raise the window, which traveller is provided with a pair of plates 22 held together by a pintle 23. Mounted upon one end of the pintle is a roller 15 which engages the window to raise and lower the same. Mounted upon the other end of the pintle and the opposite side of the plates is a roller 24 which is engaged by the lifting ribs 21 of the successive gears in the train to actuate the traveller so that the traveller is passed along from one gear to another. The plates are disposed to engage opposite sides of the casing at the margin of the guideway to hold the traveller to travel through the guideway.

The regulator is a self-contained unit and is disposed in the well of the door panel 12 into which well the window 11 is adapted to be lowered and from which it is raised by the operation of the regulator to close the opening at the top of the well.

It will be seen that in the travel up and down in the raisinn and lowering of the window, this roller follows an angular course or it may be termed a Zig-zag path as indicated by the slot 13LL appearing in one side of the gear casing in Fig. 2,

The usual connection between the roller and the window so that the window will travel with the roller, is to provide a forked member or slot in the lower sash of the window within which slot this roller is disposed so as to have a permitted lateral movement in the slot as the window is raised or lowered. Both arms of this forked member are rigid and there is necessarily a certain amount of play up and down of the roller therein. The roller is generally positioned in t-he slot from the side, the slotbeing sufficient oversize the roller to permit the insertion of the roller therein. The roller may, however, be inserted in the slot from the end. In either way there is of necessity a permitted vertical play of the roller in the slot, the objectionable character of which is particularly noticeable at the beginning of the movement of the window, in the knock of the roller against the lower sash rail in the raising of the window, and a similar knock against the lower portion of the guide member within which the roller travels at the beginning of the operation to lower the window. If t-he window does not travel evenly and freely, this knocking may occur at intervals throughout the movement of the window up or down. It has also happened that when the roller is inserted from the side in the slot and the window is not mounted carefullyl or the regulator is not properly installed that the roller will become disengaged from the slot and the window sash.

My invention resides in the provision of an improved type of connection between the window and the roller. I have here shown the roller as engaged with a window retaining member 16, which retaining member is here shown as the lower sash rail which supports the window pane for movement in the provided guide-way in the frame. The lower edge of this retaining member 16 is rounded to engage the grooved face of the roller. The other portion of the guide-way against which the roller acts in lowering the window is held under limited yielding constraint against the roller, the same being supported by the retaining member.

This other portion of the guide-way is in the form of a strap 17 which may be turned out of sheet metal as shown in Fig. 5 with a rounded face to engage the roller on the side opposite that engaged with the lower edge of the window sash. This strap is yieldingly supported at opposite ends below the retaining member 16. This retaining member carries two depending pins 18 which pass through apertures 2O in the ends of the strap so as to permit of vertical movement of the strap thereon. Encircling each pin below the strap is a spiral spring 19 which holds the strap upwardly yieldin gly against the roller. The roller is thereby clamped yieldingly between the strap and the retaining member in such manner as to prevent any vertical rattle of the roller between the strap and retaining member while permitting lateral movement of the roller within the provided guide-way. At the beginning of the movement to close the window the strap may yield downwardly to cushion the shock of the roller upon the window in case there is much resistance ottered by the window.

that I claim is:

1. In a window regulator, in combination with a window, a movable window supporting member, window operating means having a roller arranged to reciprocate through an angular course in operating the window, said supporting member provided with a retaining guide-way within which said roller travels in opening and closing the window, and means holding one arm of said guide-way yieldingly toward the other to limit the relative movement of the roller laterally therein.

2. In a window regulator, in combination with a slidably mounted window pane, a movable window supporting member, window operating means having a roller arranged to reciprocate through an angular course in operating the window, said supporting member provided with a retaining guide-way for said roller within which the roller is disposed for reciprocal travel in the opening and closing of the window, one arm of said guide-way being rigid with the window-supporting member and the other arm of said guide-way being held yieldingly on opposite sides of said roller toward said rigid arm to restrain lateral play of the roller between said arms.

3. In a window regulator, the combination with a slidably supported window, of window operating mechanism provided with a roller adapted to travel through an angular course in operating the window, and connecting means engaging said roller with the window to operate the same, comprising a guide-way for the roller, one side of which guide-way is rigid with the window and the other side of which guide-way is held under yielding spring tension toward the roller.

4t. In a window regulator, window operating mechanism having a window lifting member adapted to be raised and lowered,

a movably supported window, a retaining plate secured to the lower edge of the window and provided with a guideway within which the lifting member of the operating mechanism travels in the raising and lower- 1U mechanism having a lifting member adapted to be raised and lowered, a movably supported window, a window supporting member secured to the window provided with a guideway extending transversely the path oftravel of the window adapted to receive said lifting member, the lower side of said guideway held yieldingly in engagement with the lifting member toward the other side of the guideway.

6. In a window regulator, in combination with a movable window having a supporting plate secured to the lower edge thereof, window operating mechanism provided with a window lifting member adapted to be raised and lowered and arranged to be held yieldingly in contact with said supporting plate to travel back and forth thereover and transversely the path of travel of the window in the raising and lowering of the window.

In testimony whereof, I sign this specification.

PAUL J. NELSON.
