Filed Sept. 20, 1940 Z SHeets-Sheet 2 In ventor kaberf Dorr/es Z7 By A iiorney I Patented Dec. 8, 1942 UNITED STATES PATENT OFFICE 6 Claims.

The present invention relates to new and useful improvements in window operating means for windows of the vertically reciprocating type, such as provided for automobiles and other motor driven vehicles, and the invention has for its primary object to provide fluid operated means adapted to provide the moving force for the window.

An important object of the present invention is to provide a disk-like cylinder having a pair of blades swingably mounted therein and having a working fit in the cylinder and which are operatively connected to the window to provide for the raising and lowering movement thereof during opposite movement'of the blades and also to subject the blades to fluid means for the actuation thereof.

A further object of the present invention is to provide a mechanism of this character in which either a suction or pressure force may be employed.

An additional object is to provide novel valve control means for the feeding of the fluid to opposite sides of the blade to move the same in a manner for raising and lowering the window.

A still further object is to provide an apparatus of this character of simple and practical construction, which is eflicient and reliable in performance, relatively inexpensive to manufacture and install in operative position in the door or window frame of the vehicle and which is otherwise well adapted for the purposes for which the same is intended. o

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being hadto the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which Figure l is a side elevational view of an automobile door having the window mounted in the upper portion thereof and illustrating the invention operatively connected thereto.

Figure 2 is a horizontal sectional view through the fluid cylinder and'illustrating the arms operatively connected thereto.

Figure 3 is an enlarged sideelevational view of the cylinder with the cover plate removed and showing the frame provided for connecting to the window.

Figure 4 is a fragmentary side elevational view of a modified frame construction for connecting the arms of the blades directly thereto.

Figure 5 is a longitudinal sectional view through the control valve.

Figure 6 is a transverse sectional view therethrough, and Figure '7 is a fragmentary sectional view of the cylinder illustrating one of the adjustable screws to prevent collapsing of the cylinder walls when subjected to the fluid suction.

Referring now to the drawings in detafl, and with particular reference to the form of the invention illustrated in Figures 1 to 3 inclusive; the numeral 5 designates an automobile door of conventional construction, which includes the window opening 6 at its upper portion and within which the vertically reciprocating window I is mounted.

The usual diagonal frame member 8 is provided for the lower portion of the door and extending horizontally between the sides of the door is a bar 4, having rounded ends 4' inserted in brackets 3 and secured against end play by pins 2. A substantially flat circular cylinder 9 having a removable cover plate I0 is secured-fiatwise to the bar 4.

A pair of hub members II and I2 'are positioned in the cylinder, the hub member ll being provided with a shaft l3 which is rotatably mounted in the hollow shaft l4 formed on the hub member I2, the shafts I3 and It being disposed coaxially as shown in Figure 2 of the drawings. The hollow shaft i4 is joumalled in an opening in the rear wall of the cylinder 9 as shown at If: and at the side of the hub member ll opposite from the shaft I3 is a short shaft extension l6 which is joumalled in a recess I'I formed on the inner face of the cover plate in.

Blades l8 and I9 are secured at one end to the respective hub sections II and I2, the blades, in their present embodiment extending v radially from the hub sections and are provided at their opposite faces with sheets of packing material 20 adapted to provide an air-tight and liquid-tight working fit with the walls of the cylinder.

The tubular shaft I4 is freely mounted in a slotted opening 2| formed in a frame member 22 which is secured at its upper edge to the-bottom frame member 23 of the window. The frame member 22 is also provided with a pair of horizontal slotted openings 24 within which rollers 25 are slidably positioned, the rollers being formed on the outer ends of arms 26-26 which are secured at their inner ends to the respective shafts l3 and H.

An upper feed pipe 21 has one end communicating with the cylinder 9 above the blades l 8 and i9 and a lower feed pipe 28 has one end connected to the cylinder below the blades. The

other ends of the feed pipes communicate with

ports

29 and 30 respectively formed in the bottom portion 3| of a slidingvalve structure shown in detail in Figures 5 and 6 of the drawings. The bottom 3| of the valve is also provided with an intermediate port 32 with which a, supply pipe 33 is connected. the supply pipe leading to a suitable source of fluid pressure or suction (not shown), as desired.

A slide valve 34 is mounted on the bottom 3| of the valve structure, the slide valve being provided with a recess 35 in its bottom surface adapted to provide communication of either the pipes 21 or 28 with thesupply pipe 33 through their respective ports. The slide valve 34 is provided with an operating rod 36 having a manipulating handle 31 projecting through a slotted opening 38 formed in the inner side of the door 3.

The upper surface of the slide 34 is provided with a recess 38 within which a ball 48 is adapted to be seated; the ball being yieldably urged into position by means of a spring 4| confinedby a bridge piece 42 extending transversely across the top of the slide valve 34-. Coil springs 52 engage each end of the valve 34 to normallyreturn the valve to a central position closing both

ports

29 and 30 to maintain the window in its adjusted position.

In certain types of door and window construction the frame member 22 may be dispensed with and the horizontally extending slotted openings 43 may be formed in the flange portion 44 of the frame member 45 secured to the lower edge of the window 46 as shown in Figure 4 of the draw ings, the slotted openings in this form of the invention being adapted to slidably receive the rollers 25 of the arms 26.

In the operation of the device the suction or pressure of air fed to the pipes 21 and 28 will act upon the blades l8 and I9 to swingably actuate the same whereby to cause a similar movement of the arms 26, thus moving the roller 25 inwardly or outwardly in the slotted openings 24 and thus raise or lower the window. The pipe 33 may be connected to the intake manifold of the engine of the vehicle whereby to employ a vacuum for the actuation of the blades. When utilizing such means for the operation of the device the cylinder 9 may be provided with a quantity of oil 41 above as well as below the blades l8 and I9, whereby to suitably lubricate the walls of the cylinder. In order to prevent entrance of the lubricant into the lower pipe 28 an extension 48 is provided which extends upwardly into the cylinder and is provided with a downturned extremity 49.

In order to prevent possible collapsing of the front and rear walls of the cylinder an adjustable screw 50 is threaded through the cover plate l with its inner end abutting the rear wall.

In order to prevent settling .of the window downwardly after the same has been raised, the ends of the

slotted openings

24 and 43 are provided at their upper edges with upwardly inclined portions to form a seat for the rollers 25.

It is believed the details of construction, operation and advantages of the device will be readily understood from the foregoing without further detailed explanation.
