18 Claims.

for vertical slidable travel. The sash of the lower storm window is provided with means to support a screen either in a position overlying the window or in a position elevated above the window. The lower storm window is also provided with means adapted to cooperate with a screen disposed below the window to support the window in the elevated relationship within the window opening.

A further object is to provide a window in such window and screen assembly which has a sash frame the top rail of which is provided with a screen supporting channel extending therealong and projecting inwardly 0f the inner face of the rail and the bottom rail of which window is also provided with a screen supporting channel extending therealonng and projecting inwardly of the inner face of the rail.

A meritorious feature is that the screen supporting channel that extends along the bottom rail of the window sash has a bottom wall that projects inwardly and downwardly at an acute angle to the plane of the rail and defines a space within which the top rail of a screen may be received to support the window in the elevated position and to maintain tight fitting engagement between the window and the screen.

A further object is to provide a screen for this window and screen assembly which is adapted to be supported by the lower window or to support the window and which is adapted to cooperate with the window to form close fitting engagement between the screen and the window. This screen is provided with side rails which have flange portiOIls that form contact below the window with the outer wall of the guide channel within which the window is disposed for slidable movement. Such contact between the flange portions of the side rails of the screen and the wall of the guide channel below the window is to provide a fiy-tight seal between the screen and the window frame within which the screen is mounted below the window.

A further object is to provide a window with a metal sash the side rails of which are laterally adjustable to accommodate the window to window openings which vary slightly in size and which window sash includes supplemental top and bottom rails which are manually adjustable to maintain the side rails at their laterally adjusted positions.

A meritorious feature of the metal guide channel within which the windows are slidably mounted is that it has a plate associated therewith which is vertically adjustable to form tight fitting contact with the sill of the window frame within which the guide channel is mounted.

Other objects, advantages and meritorious features of the invention will more fully appear from the following description, appended claims and accompanying drawings, wherein:

Figure 13 is a fragment of the lower end of the guide channel within which the window is supported for vertical slidable movement showing the guide channel adjustable plate.

The window and screen assembly here shown is illustrated as supported within a window opening 3 in a building structure '20. This window opening is shown as defined by a sill 22, a header 2%, and vertical jamb pieces 26. This window opening is provided with the usual conventional vertically slidable windows 28 and 30. The jamb 26 is provided with an outer stop 32, a parting stop 3d and a suitable inner stop 36 to guide the windows 28 and 30 in their slidable movement. These windows form no part or the invention.

The invention resides in the window and screen assembly which is here shown as a storm window and screen assembly. It includes a pair of complementary upright guide channels 38 formed of sheet metal and connected at the top by a channel shaped header 48 forming an inverted U- shaped structure when disposed within the window opening. This U-shaped structureis disposed inverted within the window opening. The header member exhibits an upwardly open channel portion 42 which is received over the header stop within the window opening as shown in Figures 2 and 3.

The upright side guide channels 38 exhibit outwardly open channel portions 14 which are received over the stops 32 to secure the structure within the window opening. Each side member 38 exhibits-a pair of inwardly open guide channels within which the two storm sash 46 and as are supported for vertical slidable movement. The upper and outer storm sash 46 is supported within the outer of these guide channels and the lower and inner storm sash 48 is supported within the inner of these guide channels. The outer side wall of the inner guide channel, which is formed by a fold 5K3 in the sheet metal strip that is bent to form the guide channel upright frame piece, has a width greater than the inner side wall of the inner guide channel as will appear from Figure 4 for a purpose hereinafter set forth.

In order to accommodate this guide channel structure within window openings which may vary somewhat in vertical dimensions or wherein the sill may vary as to its angle a metal plate 52 is received within the fold 5!] and is vertically adjustable therein to form contact with the sill as shown in Figures 1 and 13.

The lower window 48 is provided, with a-metal sash which includes achannel shaped top rail 54 and a channel shaped bottom rail 56 each of which extends along and embraces a margin of the glass pane. A supplemental bottom rail memher is secured to the bottom rail '55 and exhibits an upwardly open channel portion 58 the bottom wall 60 of which projects inwardly and downwardly fromthe inner face of thebottom rail of the window at an acute angle as shown in Figures 2 and 3. This. supplemental bottom rail member has a channel portion 62 which embraces and extends along the bottom rail 56 of the sash 38 to secure the same thereto.

A supplemental top rail member is' secured to the top rail 54 of the sash. This supplemental top rail exhibits an upwardly open. channel 64 and adownwardly open channel 66 which embraces the top rail 5d as shown in Figures 2 and 3. Each of these supplemental channel rail members is secured to its-sash rail in such a manner, asv to be adjustable lengthwise therealong and to frictionally retain its position of adjustment thereover.

A side rail: Biiof channel shape embraces and extends along each vertical side margin of the glass pane as shownv in Figures 11 and 12. Each side rail overlaps at the ends the top and bottom rails 5d and 55. The supplemental top and bottom rails heretofore described embrace the top and bottom rails 54 and '56 between the two side rails 68. Each side rail 53 has a portion 10 extended over the end of the top rail or bottom rail so as to complete the frame.

Each side rail is adjustable laterally with re-' spect to the top and bottom rails and with respect to the glass pane as shown in Figure 11. Each side rail may be withdrawn horizontally relative I to the top and bottom rails and the supplemental top and bottom rails may be shifted as shown in Figure 11 so as to hold a side rail at its adjusted position. Due to this adjustment of the side rails it is possible to accommodate a window to the proper width of opening to form a tight fit within the window frame opening while permitting slidable' movement of the window. Such window frame openings differ somewhat in size and with a wooden sash it is customary to cut them to fit at the time of installation. This meta1 sash may be adjusted as above described at the time of its installation.

As seen in Figures 1, 2 and 3, a screen which is indicated as, a unit as 12 isadapted to be sup,- ported within the channel fi l of the supplemental top rail member to extend above the window 481 This screen may be positioned underneath the bottom walltiiof the channel 50 of the supplemental bottom rail: member as shown in Figure 2 to support the window in the elevated relation ship. When the screen 72. has its bottom rail seated within the channel 64 of the top rail of the lower window as shown in Figure 3 the lower window may be raised until the top edge of the screen contacts the window header frame piece which will limit the elevation of. the lower window beyond a small distance sufficient for ventilation but insufficient for unauthorized entrance.

When the screen unit is positioned with its top rail abutting the bottom wall 69 of the chan nel 'of the bottom rail of the window 48 it serves to support the window in the elevated position as shown in Figure 2 and permits full ventilation through the lower half of the window frame. The projection of the bottom wall 60 of the channel 58 at anacute angle to the bottom rail of the window forms tight fitting contact with the top rail of the screen and holds the same snugly against rattle and constitutes a fly-tight seal.

The screen itself may be of the form shown in Figures 6 through 10'of this application. The screen illustrated in Figures 6 through 10 comprises a sash frame having a top rail 14, bottom rail 16 and complementary side rails 18 secured together at their corners to form a rectangular frame. with screen wire mesh stretched across the opening in the frame and secured thereto. Each sash rail has its inner margin bent outwardlyupon itself forming a flange sz-whichextends outwardly awayv from the margin at an acute angle to the plane-of the rail as shown in Figures sand- 9. The screen wire 86 is folded over this flange anda channel strip 84 is received over the fold in thewire. and over the edge of the flange and. extends therealong all as shown in Figures 6 through 10. These channel strips not only secure the screen wire :mesh in placebut stretch it taut across the opening. and hold. it stretchedv thereacross. One side wall of each channel strip 84 is. folded-over at the cor ner as at 86 (Figure 10) over its cooperating channel stripto formv a continuous retainer about theopening inthesash.

The screensash ishereshOWn as having each side rail provided at both ends with an extension 88. One of these end extensions folds over the top rail 14 and theother end extension folds over the bottom rail 16 as shown in Figures 6, -7 and to secure the ends of the rails together to form'the rectangular sash. Each side rail 18 is so shaped by being folded upon itself as to exhibit a flange 90 which extends normal to the plane of the screen and away from the rail on the side opposite the flange 82 as shown in Fig. ures 2, 3, 8, 9 and 10. This flange 9% has a width equal to the width of the inner guide channel within which the lower window 46 is adapted to travel so that when the screen is supported either above the lower window'or below such window the flanges 90 extend across thischannel and engage the outer wall of the channel as shown in Figure 4 forming a fly tight fit therewith. These flanges 90 are of such a length as to terminate short of the bottom margin of the bottom rail '56 of the screen as shown in Figure 3 so that when the bottom rail 16 is seated within the channel 64'. as shown in Figure 3 the flanges 90 extend across the top rail of the lower window 48. When the screen is placed below the window to hold it in the elevated position as shown in Figure 2 it is inverted, that is thc'rail 16 isused at the top and the flanges 98 extend underneath the window as shown in Figure 2.

The screen may be used to hold the inner window in the elevated position as shown in Figure 2 or the screen may be placed in an out-of-theway position above the lower window as shown in Figure 3. In Figure 3 the upper window 46 might be lowered if ventilation was desired through the upper half of the window or the screen might be disposed as here shown for outof-the-way disposition as in the winter time when both storm sash are in use. Obviousl if desired the screen might be supported within the channel 58 and the lower window partly elevated or completely elevated in which the position the screen would not be in use.

This particular assembly is capable of being readily installed within a window opening and of being left permanently in place and is adapted to serve the demands of .both winter and summer use. It represents an attactive, neat appearance and is of such a compact construction that it is receivable within a relatively small space so as to fit an conventional window opening.
