7 Claims. 1

My present invention; in its broad aspect, has reference to improvements in simple; effective and practical means for lowering automobile windows, and is tobe used in conjunction with conventional gear. mechanism, and the like, for raising an automobile window"; ordinarily, it is desirable to more quickly lower a window than it is to raise a window since, among other'things, on approaching an inter-section, slowing up, or making a turn, it is required that a hand signal be given. Also in regulating the extent which a Window is opened, it is-usually opened wide and then gradually closed to the extent desired for proper and comfortable ventilation. My invention contemplates the use of compressed air means for actuating the window operating quadrant during the openingcycle and releasingthe usual lever actuating pinion, and then re-engaging the usual lever actuating pinion and discontinuing the compressed air means on the closing cycle so that the usual means may be employed in closing the window. The compressed air to operate my device may be supplied from a compressed air tank refillable at any gasoline filling station, or may be supplied by a small pump connected With a power take-01f from the fan belt.

My invention may be applied with little modification to conventional car body and window construction, and is simple and sturdy and has no fragile or intricate parts which are likely to get out of order or to be deranged or broken in use.

Other and equally important objects and advantages of my invention will be apparent from the following description and drawings, but it is pointed out that changes in form, size, shape, materials, construction and arrangement of parts is permissible and within the purview of my broad inventive concept and the scope of the appended claims.

In the drawings, wherein I have illustrated a preferred form of my invention:

Figure 1 is a side view of the assembly as applied to a conventional car door, and

Figure 2 is a view of a modification of my device.

In the drawings wherein like characters of reference are used to designate like or similar parts throughout the several views:

The numeral l designates a conventional type of automobile door or body, having the usual sliding glass window 2, in a frame 3. A conventional toothed quadrant 4 is pivoted at 5 and has a lever 6 which is pivoted to the quadrant as at land which raises and lowers the window when the pinion 8-in mesh with the teeth of the quadrantis turned by a handle or operating lever (not shown).

According to my invention, the lever Bis extended as at 9, and a second lever lll--similar to the lever 6is pivoted to the quadrant as at H and is extended as at l2 and pivotally connected at It to the extended end Q-oflever 6'. The pinion B ismounted on the circular enlargement [4 between the arms [5- and [Got a bell-crank lever ll, one arm l6 of which is pivoted to the door asat l8. To the other arm [5 of the bell-crank lever I! is pivoted a link I9, pivotally connected as at 26, to a pivoted arm 2| on the door. A spring 22 normally pulls the arm forward, and a link 23 pivoted to the arm 2| slides in the keeper 24 and engages a cam 25 on the handle 26. The handle 26 is connected with a valve 2'! to open and close connections 28 and 29 between a compressed air pipe, the connection 29 of which leads to a compressed air tank 30, and the other connection 28 of which leads to a cylinder 3|. The compressed air tank 30 has a filling nipple 32 to recharge the tank at any gasoline station air line when desired. The cylinder 3i is pivoted at one end as at 33 and has a piston 34 with an adjustable rod 35 adjustably and pivotally connected to the lever ID as at 36.

Under ordinary circumstances, to raise the window, the pinion 8 is rotated by a suitable handle (not shown), but to lower the window, the handle 26 is moved to disengage the pinion 8 from the quadrant 4 and to establish communication through valve 21 between compressed air tank 30 and cylinder 3| whereupon piston 34 is moved to move the quadrant 4 and levers 6 and Ill to quickly and easily open the window. The action of the piston is cushioned by a body of compressed air at the opposite sides of the piston and a bleed opening 31 is provided to permit its operation. When the window has been opened, the handle 26 is moved to normal to re-engage the pinion 8 with quadrant 4 to permit raising the window in the usual manner.

In Figure 2, a push pin 38 is substituted for the handle 26, and is mounted in brackets 39 and has a spring 40 for normally moving the same upwardly. A pair of cams 4| and 42 engage respectively a valve operating rod 43, and the slide plate 44 carrying the pinion 8. The rod 43 is mounted in brackets and has a spring 45 to move it against the cam 4|, and the plate 44 has an arm 46 with opposed rollers 41 and 48 between which cams M and 42 operate to move the plate 44 which has opposed vertical supporting arms 49 slidably mounted in keepers 50. By this structure, downward movement of the push pin 38 retracts the plate 44 to disengage pinion 8 to release quadrant 4 and open the valve 21 to lower the window by .operation of the piston by compressed air, and raising of the pin by spring 40, closes the valve 21 and re-engages the pinion 8 with the teeth of the quadrant for normal operation in closing the window.

From the foregoing, it is believed that the operation and advantages of my invention will be apparent, but it is again emphasized that interpretation of its scope shall only be conclusive when made in the light of the subjoined claims.

I claim:

1. A window opening device for use with an automobile window having an operating pivoted toothed quadrant, and a pinion for operating the quadrant to close the window, comprising a movable mount for the pinion, a source of compressed air, a cylinder and piston assembly, a lever on the quadrant, a rod connected with the lever a second lever on said quadrant pivoted to said first lever, said second lever pivoted to said window for the raising and lowerin thereof said first rod connected to said cylinder -and piston assembly, a valve in the compressed air line from the cylinder to the source of compressed air, actuating means operatively connected with the valve and with the movable mount for the pinion to release the pinion from the quadrant when the valve is opened, and to re-engage the pinion when the valve is closed.

2. The invention as defined in claim 1 wherein the cylinder has a bleed opening, the levers are connected with each other at an angle, and the piston rod is connected with one lever and the window with the other.

3. The invention as defined in claim 1 wherein spring means are provided to return the pinion to a position in engagement with the quadrant, and wherein the source of compressed air includes a compressed air tank.

4. The invention as defined in claim 1 wherein the valve and pinion operating means includes a pivoted handle.

5. The invention as defined in claim 1 wherein the valve and power operating means includes a slidable pin, and a spring for returning the pin to its normal starting position.

6. The invention as defined in claim 1 wherein the operating means includes a pivoted handle, a cam on the handle, and relatively connected links and levers connected with the pinion and engaged by the cam, and a spring for returning the levers to normal position.

7. The invention as defined in claim 1 wherein the pin is provided with a pair of cams operatively associated respectively with the valve and with the pinion, and wherein the piston has an adjustable piston rod.
