A downwardly disposed flange 26, secured to the outer edge of the diagonal member 25, serves to support the bracket 4 from the interior face of the end member 22 by being welded or brazed thereto. A short horizontal toe 21, rigidly attached to the lower edge of the diagonal member 25, serves to support the bracket 4 from the interior face of the end member 22 by being welded or brazed thereto. The short horizontal toe 21, rigidly attached to the lower edge of the diagonal member 25, serves as a pivotal support for a pane I when its lower edge is placed thereon. It will be apparent from an examination of Figure that in large scale production, the brackets 4 may be fabricated from commercial angle iron by rst removing a portion of one flange therefrom, and then bending the remaining flange into the desired angle to form the toe 21.

For pivotally supporting the panes I from the frame 2 a number of the brackets 4 are attached to the inner faces of the end members 22, with each bracket being placed in the same horizontal plane as a like bracket situated on the opposite end member, and with the diagonal members 25 and the horizontal toes 21 aligned with one another. A pane I is now placed on each pair of brackets 4, with the lower edge of each pane being pivotally mounted on the horizontal toes 21 as may best be seen in Figure 1.

For locking the panes in closed position as shown in solid line in Figure 2, and for holding them in the intermediate position as shown in solid line in Figure 2, and for holding them in the intermediate position between this and the open position shown by phantom lines in the same figure, the independent regulating mechanisms 3 are employed. Although each of the panes has been supplied with a regulating mechanism 3 at each end thereof, this is a matter of convenience for the occupant of the room as either of the mechanisms may be used in controlling the position of the pane. However, when the pane is locked to the frame, and particularly if the window is being subjected to vibration such as in a trailer, I have found it desirable to place both of the adjustment mechanisms 3 in the locked position to prevent unnecessary strain being placed on the pane due to sudden shock.

In structure the regulating mechanism 3 includes a lever 29 that is rotatably mounted on a machine screw 28 which is perpendicularly disposed on the interior face of the end member 22, and located above the upper portion of the diagonal member 25 as best seen in Figure 2. Disposed on the end of the lever 29 adjacent to the A'pane I is a horizontal pin 30 that serves to rotatably support a resilient roller 3l which is not only used as a rest for the pane I when it is in the partially open position, but as a locking means when the pane is placed in the closed position. Situated on the opposite end of the lever 29 and used for actuating same is a handle 32 which I have found convenient to form by bending a portion of the lever 29 at an angle of substantially 90 degrees thereto as best seen in Figure 2.

It will be apparent that for the pane I to be retained in an intermediate position by resting on the roller 3I that frictional means must be employed to prevent the lever 29 from rotating downwardly due to the weight of the pane which it supports. To achieve this result I rotatably support the lever 29 on the machine screw 28 between a head 32 and a washer 33, with the entire assembly being held on the interior face of the end member 22 by a self locking nut 34 that engages the machine screw as it emerges on the outer face of the end member. Thus by revolving the head 32 the desired friction may be placed upon the lever 29; sufficient to allow the lever to be moved by the operator toregulate the position of the pane, but great enough to prevent the lever from rotating downwardly due to the weight of the pane which it supports.

In placing the pane I in the closed position, which is automatically the locked position, the handle 32 is pressed downwardly to cause the roller 3I situated on the opposite end of the lever 29 to move upwardly in a vertical arc. and rotate along the inner face of the pane as it pivots same on its lower edge into the closed position. It will be obvious that any vertical component of force generated by the upward movement of the arm 29 and tending to lift the pane I from the brackets 4 as it pivots same into the closed position is eliminated by the use of the roller 3|.

To prevent the panes I from being slid inwardly and removed from the frame 2 by wouldbe trespassers or thieves, a vertical strip 36 is provided that extends inwardly past the outside edge of each pane and is removably secured to each flange 24 by a number of machine screws 31, as best seen in Figure 1. It will be noted that a number of vertically disposed slots 38 located along the inner edge of the strips 36 allow the arms 29 to project therefrom in a vertically movable position. Thus with the strips 36 in place and with the upper end of each diagonal member 25 in contact therewith, it will be seen that neither can the panes I be removed from the frame 2, nor can they while remaining in the frame be shifted to the top or bottom thereof to secure unlawful entry from the outside, as the end portion of each pane is enclosed in an inwardly extending trapezoidal section which is bounded on the top and bottom by the brackets 4, on the inside by the strip 36, and on the outside by the flange 23.

In order to both weather proof the window as well as to eliminate rattles that may arise therefrom when same is installed in a vehicle I have provided a U-shaped molding 39, that is fabricated from a resilient material, and which I slip over that portion of the lower edge of each pane that is not resting on the brackets 4. A depending member 40 aixed to the lower portion of the U-shaped molding 39 serves to conduct any water or moisture accumulating on the outside of the panes downwardly from one to the other, and thus eliminates the possibility of any inward seepage which might take place at the horizontal junction of the panes. Although I have found'from experience that rubber gives excellent service when used as a material for the molding 39, it will be apparent that any weather and water proof material such as cellulose acetate or a similar material may be used for this purpose with equally satisfactory results.

For weather and rattle proofing the end members 22, a vertical strip 4I which may also be made from rubber, cellulose acetate, or a similar material is aiixed to the interior face of the flange 23 as best seen Figure 3. It will be noted that the strip d! encloses that portion of the junction between adjacent panes which is not covered by the molding 33. As a further precaution against rattling, as well as to prevent chipping or breaking of the panes when they are rapidly placed in the open position, a number of resilient pads l2 are placed along the outer face of each strip 35 and so disposed as to serve as a rest for the upper edge of the panes I when same are in the fully open position as best seen .in Figure 2. For holding the pads 42 in the desired position on each strip 39 I have employed a suitable adhesive or glue.

Due to the simple mechanical structure of my window the operation of the device will readily become apparent from an examination of Figure 2. Each of the panes I is independently controlled from the balance of the panes by dual regulating mechanisms 3, either of which may be used for this purpose at the option of the 0perator. To place a pane in the closed position, one of the handles 32 is pressed downwardly to cause the opposite end of the lever 29 to swing upwardly in a vertical arc, with the upper portion of the pane I supported on the resilient roller 3|. Thus as the upper portion of the pane I is forced inwardly toward the frame by the roller 3|, the lower edge of the pane I pivots on the pair of supporting brackets 4 until the pane is parallel with the frame and the lever 29 is normal thereto. In this position the pane is not only closed but locked, for as the roller 3| is forced into the closed position it is also slightly compressed and tends to retain the lever 29 in the perpendicular position with relation to the pane until an upward force is applied to the handle 32. Therefore, it will be apparent that the vertical component of force necessary to revolve the lever 29 downwardly and allow the pane to assume the open position cannot be applied from outside the window irregardless of the pressure applied.

In opening the window the process is merely reversed with the handle 32 being raised upwardly to cause'a downward movement of the opposite end of the lever 29 that supports the roller 3|. Thus as the roller 3| moves downwardly away from the frame 2, the pane pivots inwardly on its lower edge due to gravity, with its position being determined by that of the roller 3|. It will be noted from an examination of Figure 2 that in the closed and intermediate position the pane is resting on the roller 3| but in the open position, is resting on its upper edge against the pad 42, with the lever 29 disposed between the diagonal member 25 and the lower portion of the pane.

For the removal or replacement of panes which may be broken or damaged after the assembly of the window has been completed, the strips 36 are removed from the flanges 24 and the levers 29 revolved into a position where the panes may be conveniently slid edgewise from the frame. It will be obvious that in the assembly of the window after the frame 2 has been installed in the desired position that the levers 29 may be revolved to a similar position, the panes slid into the frame 2 edgewise using the diagonal members 25 as guides, and when the operation has been nished aixing the strips 36 to the flanges 2L'. to complete the window structure.

While the particular apparatus herein shown described in detail is fully capable o1 attaining the objects and providing the advantages herein before stated, it is to be understood that it is merely illustrative of the presently preferred form of my invention, and that I do not mean to limit myself to the details of construction or design herein shown, other than dened in the appended claims.

I claim:

1. A window structure including a substantially rectangular frame provided with two laterally spaced vertical end members, a plurality of brackets supported as horizontally aligned pairs on the facing surfaces of said end members, each of said brackets having a horizontally disposed supporting portion, a plurality of substantiallyrectangular panes extending arcoss said frame with the lower edge of each of said panes near the ends of each of said panes resting freely on said supporting portions of a pair of said brackets, resilient vertical strips having rigid backing means mounted on said end members outside and adjacent said supporting portions for engagement by marginal end portions of the panes on the outer surfaces of the panes, elongated resilient elements substantially U-shaped in cross section horizontally disposed between said vertical strips and each having a marginal lower edge portion of one of said panes received therein, a plurality of independent lever means pivotally mounted on the facing surfaces of said end members and extending from inside toward the outside, the pivot of each lever means being substantially in the horizontal plane passing through the horizontal median of each pane, and the length of the lever means from the pivot to the inside surface of the pane being such that when the lever is substantially in a horizontal position the pane is urged against said resilient vertical strips, a depending flange on the outside edge of each of said horizontally disposed resilient elements for engagement by an upper marginal edge portion of the next lower pane when said next lower pane is urged against said vertical strips, and means secured to the inside of the frame and disposed inwardly of said panes to prevent inward removal of the panes from the frame.

2. A window structure in accordance with claim 1 in which said lever means are provided at their outer ends with resilient end pieces for engagement with the panes when the lever means are substantially in a horizontal position.

3. A window structure in accordance with claim 1 in which each of said brackets includes an inclined portion merging into said horizontally disposed supporting portion adjacent the lower edge of the pane resting thereon and extending upwardly and inwardly from said supporting portion.
