4 Claims. (Cl. 296-44) This invention relates to Ventilating window locks for automobiles.

It is an object of the present invention to provide a Ventilating window lock for automobiles which is particularly designed for the front door Ventilating windows and wherein the Ventilating window is automatically locked in the closed position when the door window is closed completely.

It is another object of the present invention to provide a Ventilating `window lock for automobiles of the above type which eliminates the conventional lock now in use, which is at best diiicult to operate.

Other objects of the invention are to provide a Ventilating window lock for automobiles bearing the above objects in mind which is of simple construction, has a minimum number of parts, is inexpensive to manufacture and eflicient in operation and use.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Figure l is a side elevational View shown partly in section and broken away of a preferred embodiment of the present invention shown in operative use;

Fig. 2 is a horizontal sectional View taken along the line 2 2 of Fig. l;

Fig. 3 is a Vertical sectional View taken along the line 3 3 of Fig. l;

Fig. 4 is a View similar to Fig. 2 but illustrating a modilied form of the present invention; and

Fig. 5 is a vertical sectional View taken along the line 5-5 of Fig. 4.

Referring now more in detail to the drawing, and more particularly to Figs. l through 3, indicates generally an automobile of any suitable type having the usual front doors 11 and having the usual window frame 12, in the forward portion of which is the Ventilating window 13 by means of the vertically aligned pins 14, in a manner well known to those skilled in the art. The door 11 also includes the usual vertically adjustable window or glass 15, the Ventilating Window 13 and the door window 15' being adjusted in the usual manner by means of the handles and other mechanisms, not shown.

In the practice of my invention, means are provided for automatically locking the window 13 in the closed position when the door window 15 is closed or raised to its highest point and include the provision of a rectangular bar 16 secured along the inner face of the door window 15 along the forward edge thereof, the bar 16 extending to the upper edge of the glass 15 and overlapping the vent Window 13, as shown in Fig. 2. The adjacent surface of the Ventilating window 13 is provided with a felt lining 17. A second bar 18 is similarly secured to the outer face of the door window 15 in lateral alignment with the bar 16. However, the upper end of the bar 18 terminates a considerable distance below the upper end of the bar 16, the adjacent surface of the Ventilating wind-ow 13 being pro- States Patent() Nice vided with the felt pad 19. Thus, when the door window 15 is in its lowermost position or raised to the position of Fig. 1, the Ventilating window 13 may be opened and rotated outwardly as shown in phantom in Fig. 2. How ever, upon raising the glass 15 further and closing the same, the bar 18 will be moved upwardly into engagement with the outer face of the Ventilating window 13 and will prevent the same from being opened by unauthorized persons, the door 11 being of course locked. The window may not be opened inwardly or forced due to the bar 16. By means of this construction, the conventional type of lock now in use and which is often difficult to operate is entirely eliminated. The felt pads 17 and 19 may, of course, be secured or mounted on the inner faces of the bars 16 and 18, as will be apparent to those skilled in the art. To open the Ventilating window lock,I it is only necessary to lower the door window 15 until the outside bar 18 moves out of engagement with the Ventilating window 13, whereupon the Ventilating window can then be opened by pushing or by a mechanism provided for that purpose.

Referring now particularly to Figs. 4 and 5, there is shown a modified form of the present invention wherein the rear vertical edge of the Ventilating glass 13 is provided with a frame member 20 having a vertically extending and inwardly extending groove 21. A channel-shaped frame member 22 is secured to the adjacent vertical edge of the door glass or window 15 and is integrally formed with a vertical rib 23 which is received within the groove 21. The rib 23 extends upwardly about one-half the height of the channel-shaped member 22 from the lower edge thereof in a manner similar to the bar 13 of the previous form, and upon the window 15 being raised above the half open position, the rib 23 will engage the groove 21 and automatically lock the vent window. r

In other respects the form of the invention shown in Figs. 4 and 5 is the same as that shown in Figs. 1 through 3 and like reference numerals identify like parts throughout the several views.

While various changes may be made in the detail constructions, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

What I claim as new and desire to protect by Letters Patent of the United States is:

1. In a vehicle window having a Ventilating window mounted at the forward portion thereof and movable about a Vertical axis, and a rear window which may be raised and lowered, that improvement which comprises interlocking means carried by the adjacent Vertical edges of said Ventilating window and rear window adapted to be engaged when the rear window is raised above a predetermined point, and to be disengaged when said rear window is lowered below a predetermined point, said inter engaging means comprising the provision on the outer face of the rear window of a Vertical bar xedly mounted thereat, said bar extending upwardly from the lower end of the rear window substantially one-half the height thereof and being in overlapping relationship to the adjacent edge of the Ventilating window and adapted to engage the same upon the rear window being raised above one-half its open position whereby to prevent the Ventilating window from being rotated outwardly.

2. In a Vehicle window according to claim l, including a second bar secured to the inner face of the rear window and in laterally aligned relationship to said rst bar, said second bar extending substantially the height of the rear window and abutting the inner face of the Ventilating window.

3. In a vehicle window according to claim 2, the inner faces of said lrst and second bars being lined with felt.

4. In a vehicle window having a Ventilating window mounted at the forward portion thereof and movable about a vertical axis, and a rear window which may be raised and lowered, that improvement which comprises interlocking means carried by the adjacent vertical edges of said ventilating window and rear window adapted to be engaged when the rear window is raised above a predetermined point, and to be disengaged when said rear Window is lowered below a predetermined point, said interengaging means comprising a vertical frame member secured to the rear vertical edge of the Ventilating window, said vertical frame member at the rear face thereof having a Vertically extending groove extending from end to end thereof, and a second channel-shaped frame member mounted on the forward edge of the rear window and extending .sub-
