. 1.1m FOR AUTOMOBILE WINDOW GLASS i Application filed March 27, 1929. Serial No. 350,267..

This invention relates to window activating mechanisms, and more particularly to a device for effecting sliding movement of a window in respect to its supporting structure.

An object of the invention is theprovision of adevice adapted to be installed within a relatively small space, and operatively connectedto aslidi'ng window so'as to effect opening or closing-of that'window. As such, the device ispeculiarly adapted'for use in connection with the windows of vehicles, because of the comparatively small space within which the operating devices for vehicle windows, must beconiined. i

A further object is the provision or a quick acting and irreversible window activating mechanism, the purpose being to provide a' mechanism by means of whichthe window may be movedfrom fully opened to fully closed position, orvic'e versa, by rotating an operating handle through substantially only 90, in contradi'stinction to' the conventional window operating mechanism which -re quires that the operating handle be rotated several times to effect moving'of the window from one extreme position to the other.

The invention possesses other objects and advantageous features, some of which, with those enumerated, will'be set forth in the following description'ofthe inventions particular embodiment whichis illustrated in the drawings accompanying and forming a part of the specification.

Referring to the drawings: Figure 1 is an inside elevation of an automobile door, portions of theupholsteryhaving been broken away-to better'disclose the nature of the invention. -The window and operating mechanism associated therewith, are shown in the positions assumed thereby when the window is fully closed.

Fig. 2is a View similar to "Fig. .1, with the window moved tofully opened position.

Fig. 3 is an enlarged, detail vertical. sectional view taken upon the line 3'3 of Fig. 1, with the direction of viewas indicated. Fig. 4 is an enlarged, detail verticalsectional View taken upon the line l4c=of Fig. 2, with the direction ofview asindicated} legs 19 thereof.

In terms of broad inclusion, the window activating mechanism of the present inven-, tion, comprises a spiral rod mounted for rotary movement about theaxis of the spiral, ,1 described by the rod, and operatively con- E1 nected to a'sliding window to eifect opening or closing of the window when the rodis rotated. -'"j Specifically describing the inventionin its; preferred embodiment, it; is herein shown and described as being mounted within a ve hicle door 6 such as that conventionally employed upon closed automobile-bodies: This door comprisesan outer panel 7, and up holstery 8 upon the inner face thereof, these parts being supported by a suitable jframework 9. An aperture 11 is formed in the upper portion of the door 6, and this'a'per-' ture is, adapted to be optionally closedor. opened a sliding window 12. This1window may be guided in any cohvenientmanner, and since the guiding means for the window, constituteno portion of the present in vention, theyhave not been herein detailed.

-A channel-shaped strip 16 is afixed to the lower edge of the window 12, in any convenient manner. Preferably an insert 17 of felt orfother suitable cushioning material, is interposed between thestrip 16 and the window, as indicated upon Fig. 4. This strip 16 is. provided with a U-shaped bracket 18, the legs 19 of which extend'downwards' from the under side'of the strip 16. Spaced rollers 21' are journalled in the bracket 18, between the A.shaft 22is journalled within a brace 23- whichforms' a portion'of the framework 9 of the door, and extends across the space 2% insidethe door 6, between the upholstery 8' and the exterior panelling 7. An additional brace 26 may extendacross the framework 9, to provide a seat for a bracket 27 within.

which the inner end 28 of the shaft 22 is journalle'dl A nut 29 and washer 31aresecured to the inner end 28 0f theshaft 22, inside the bracket 27 to restrainthe shaft 22 against longitudinal displacement. The shaft 22 extends through the upholstery 8 and through an, elongated collar 32, softhat its inner end 33' is spaced far-enough-from the upholstery we" v 8, to permit easy operation of a handle 34 which is rigidly attached to the inner end 33 of the shaft 22. A nut 36 secured to the end 33 of the shaft, prevents displacement of the handle 34 therefrom A rod 37 is rigidly attached to the shaft 22, as by welding, and extends therefrom in the form of'a spiral, as clearly shown upon Figs. 1 and 2. This rod passes between the rollers 21, with the result that when the shaft 22 is turned, carrying with it the rod 37 the window 12 is either pulled toward the shaft 22, or pushed therefrom, depending upon the direction of rotation. Preferably the plane of the spiral described by. the rod 37, coincides with that of the window 12, with the result that the entire operating mechanism may be received within a space 24 within the door, of minimum thickness. 7

' In its preferred form, the spiral described by the rod 37, coincides with the mathematical curve delineated as a spiral of Archimedes, the distinguishing feature of which, is that the angle varies directly as the radius vector. This type of spiral is most desired, because a constant rate of rotation of the shaft 22 will result in a constant rate of movement of the window 12, if this particular spiral is employed. It is also desirable to position the shaft 22,

- not directly under the bracket 18, but far enough to one side of a point directly therebeneath, to bring that portion 41 of the rod 37,which is received between the rollers 21, into substantial parallelism with the lower edge of the window 12. As a result of this feature, a mechanical advantage is developed, which assists in raising the window with a lesser amount of force exerted upon the shaft 22, because when the shaft 22 is turned to the right, as viewed upon Fig. 1, that portion 41 of the rod 37, which, at that time is between the rollers 21, will then be given a slight upward movement, whereas if the shaft 22 were directly below the bracket 18, the portion 41 of the rod 37 would not move upwards, but would move in a direction truly parallel to the under side of the window, developing no upward push other than the wedging action resulting from the increased radius vector of the spiral.

A. coil spring 42 is undertension between the frame 9 and the rod 37, urging the rod and shaft 22 to rotate in that direction which will resultin raising thewindow 12. Preferably this spring is proportionedand positioned so that the turning moment set up in the rod 37 by the downward pressure of the window 12, is substantially neutralized by the force of the spring 42. v

The operation of my improved window activating mechanism is believed obvious from the above description of its constituent parts. As the shaft 22 is turned to the right as viewed upon Fig. 1, the distance between the shaft 22 and that portion 41 of the rod 37 disposed between the rollers 21, is increased,.pushing the window 12 upwards.

Conversely, rotation of the shaft in the opposite direction, will result in pulling the window downwards to open the aperture 11. It is apparent therefore, that movement of the window from fully opened to fully closed position, and vice versa, may be effected by imparting to the handle 34, practically only 90 of rotation, in contradistinction to theconventional window activating mechanisms which require that the handle be turned several times to move the associated window from one extreme position to the other. On account of the relatively small angle between the lower edge of the window 12 and a line drawn tangent to that portion 41 of the rod 37 disposed between the rollers 21 at any particular time, any force exerted downwards upon the rod 37 by the upper roller 21, will develop a very small component tending to produce rotation of the shaft 22.-,This feature results in making the device irreversible so that the window can not be opened by any means other than by turning means being associated with the pivoted end of the rod.
