Claims. (Cl. 160-91) My invention relates to an improvement in window construction, wherein it is desired to provide a combination storm and screen window construction.

One of the usual difficulties in owning a home in the colder regions of the country lies in employing storm windows during the cold seasons of the year and in applying screens during the warmer portions of the year. Storm windows and screens are normally of a size to enclose the entire window and are thus awkward to apply and remove. This is particularly true in the case of storm windows, as the size of these storm windows makes them heavy and hard to handle.

'This is doubly true if there is even a slight wind,

due to the area of the windows.

It would often be of advantage to have storm windows both during the warm seasons of the year and the cold seasons. During the colder portions of the year storm windows serve to'restrict the heat loss through the windows. In the warmer seasons of the year storm windows could also'restrict the entrance of heat into the house.

In order to provide proper ventilation, particularly in the summer time, it is desirable that the windows be easily opened. Also in the summer time, it is almost essential that the window opening be protected by a screen.

It is the object of the present invention to provide a window equipped with two sets of slidable sashes, one of which is positioned internally of the other. In combination with the outer set of sashes, I provide a screen which fits in the area beneath the uppermost sash of the outer pair and the bottom of the window frame. Due to the fact that the outer sashes may slide, it is easily possible to raise the lower sash of the outer pair so that ventilation may be easily obtained through the screen when the lower sash of the inner pair is raised. At the same time, however, when the lower sash of the outer pair is in lowered position, the window frame is equipped with a storm window which will assist in limiting the passage of heat. A

An object of the present invention lies in the provision of a storm window comprising upper and lower sashes positioned parallel to the main upper and lower sashes of the window frame and which may be operated individually and independently. As a result either the upper or lower sash of the inner set of sashes may be operated at will, while the outer sashes provide a storm window therefor. At the same time, however, either outer sash may also be independently operated when desired to provide any desired degree of ventilation.

A further feature of the present invention lies in the fact that the screen and the uppermost sash of the storm window are in superimposed relation. The screen is removably supported in place and may be detached when desired. When the screen has been removed the outer sash of the storm window may also be readily removed by merely sliding this sash downwardly. Thus the screen and one-half of the storm window may be readily removed, and the remaining sashes may be easily manipulated in order to wash the same. Alternatively by removing the screen all of the surfaces of all of the windows may be cleaned if it is so desired.

A further feature of the present invention lies in the provision of a, double sash storm window and in the provision of a screen which normally is located in the path of movement of one of the sashes of the storm window. Thus the screen normally locks one oi' the sashes in position and no special locking apparatus or weights are required in order to hold the storm window sashes in the desired position.

A further feature of the present invention lies in the provision of a screen which normally ts tightly between the lower edge of a storm window sash and the lower portion of the window frame. This screen is slidably and pivotally supported in such a manner that when it is desired to pivot the screen outwardly, the upper edge of the screen drops a suicient distance to permit the screen to pivot freely. In other words, the screen moves out of engagement with the adjacent storm window sash as it pivots.

These and other objects and novel features of my invention will be more clearly and fully set forth in the following specification and claims:

In the drawings forming a part o'i my specication:

Figure 1 is a vertical section through my window showing the construction thereof.

Figure 2 is a view similar to Figure 1, illustrating the storm window in open position.

Figure 3 is a perspective view of a portion of the track or slides in which the storm window sashes and screen are located.

Figure 4 is a view similar to Figure 3, showing a portion of the track opposite to the portion shown in Figure 3.

Figure 5 is a detail View of the screen.

.Figure 6 is a sectional view of a modified form of channel strip.

The window A includes a. window frame I0 of any suitable type to which has been applied upper and lower storm window sashes. The frame I0 includes a head jamb II, side jambs I2 and a sill I3. A window stop I4 extends along the vertical sides of the side jambs I2 and across the top of the window, forming a channel I5 for the lower window sash I6 between the window stop I4 and the parting strip Il. A second groove or channel I9 is provided for the upper window sash 20 between the parting stop Il and the opposed of an upper portion channels 2|. These channels 2| are not normally provided on a window frame and take the place oi' the usual window stop which forms the outer portion of the sliding groove i9 for the upper window sash. l

The channels 2| are merely strips of metal. or otherV suitable material, channel-shaped in cross section as best seen in Figures 3 and 4 of the drawings. These channels 2| are secured in place with the inner flange thereof in contact with the outer surface of the upper window sash 20. The

achannels extend from top to lbottom of the window frame opening between the sill i3 and the head jamb Ii, and are held in place by any suitable means, such as by nails orrscrews 22. f

It is important to note that the lower storm window sash 23 is in place between the opposed channels 2| at the time these channels are inserted in the frame. Alternatively one of the channels 2| may be secured in place, the corresponding edge of the lower storm window sash 23 may be embraced therein, the opposite channel 2| may thenbe inserted to enclose the opposite edge of the storm window sash 23, and the storm window may then be pivoted into the frame, moving the channel 2| into proper position against the outer surface of the window sash 2o. The channels 2| form a sliding channel for the lower storm sash 23 so that this sash 23 may be moved from lowered position shown in Figure 1 to elevated position shown in Figure 2.

A second channel is provided externally of the channel 2|. This outer channel may be formed by an angle iron strip 24 composed of a base ilange 25 and a right angular flange 28 connected thereto. The iiange 26 isarranged parallel to the outer ange of the channel 2|. The outer channel is thus formed by the outer ilange of the channel 2|, the -base ilange 25 and the ilange 26. Channel shaped strips, similar to the channels 2| may be used if desired in place of the angles 24, but the angle strips are preferred.

An angle iron strip 21 is secured to the under surface of the head lamb The ends of the angle strip 21 adjacent the side jambs I2 are provided with mitered corners to cooperate with similar mitered corners on the angie members 24.

As the angle strips 24- extend` from the top of the frame only about one-half of the distance to the sill I3, these strips may be fully attached bcfore the upper storm window sash 29 is inserted therein. After the angle strips 24 are attached,

.the upper storm windowsash 29 is inserted in the channel thus formed from the bottom, and moved upwardly into the position shown in. Figures 1 and 2 of the drawings. The screen 3U illls the space between the side jambs i2, the lower edge 3| of the storm window sash 29, and the sill i3. The screen 30 may be formed in any suitable way, comprising a frame 32 and a screen `element 33 supported thereby.

The screen 30 is constructed as best illustrated in Figure of the drawings with a pair of oppositely projecting

pivots

34 and 35 projecting from opposite sides thereof. These

pins

34 and 35 are designed to maintain the upper portion of the screen within the window frame l0. The lower edge of the screen is illustrated as being held in place by friction. Any suitable hook or other fastening means may beprovided to hold the screen 30 in its proper position.

The lower extremity or one of the strips 24 is constructed as best illustrated in Figure 3 of the drawings. A portion of the ange 25 is out awa-y from the remainder of this flange, adjacent this 4 lower extremity. This strip` 24 is held in place in any suitable means, such as by the nails or screws 31. A vertical slot 39 having an outwardly turned lower end is provided in the lower extremity of the angle strip below the level of the lower edge 3| of the upper storm window sash 29. This slot 39 is provided to accommodate the pivot pin 35, which may slide vertically and outwardly therein. The pin 35 is inserted axially into the slot and when once in place restricts the movement of the screen 30.

The opposite end 40 of the other angle strip 24 is provided with alower portion'4l of the flange 25 turned rearwardly to overlie an edge of the side jamb |2. This lower portion 40 is provided with a vertical slot 42 therein having an outwardly turned lower end, said slot being in opposed relation to the slot 39 and below the level of the lower edge 3| of the upper storm window sash 29. A transverse slot 43 is provided in the flange 26 of the angle and extending into the portion 4| of the flange 25 thereof. Thus when the pin 35 is inserted in the slot 39, the 0pposite pin 34 may be inserted through the slot 43 into the vertical slot 42.

The transverse slot 43 is positioned intermediate the upper and lower ends of the slot 42 so that the pin 34 will not be in registry with this slot in either extreme position of the screen 30. When the screen is in its normal closed position, as 1llustrated in Figure 1 of the drawings, the pin 34 will be in the upper portion of the slot 42 above the level of the slot 43. When the lower edge of the screen 30 is pushed outwardly so that the screen assumes the position illustrated in dotted outline in Figure 2 of the drawings, the pin 34 will be engaged in the lower extremity of the slot 42. Thus it is necessary to elevate the screen to its mid-position before the same may be removed, thus eliminating the chance that the screen will become accidentally disengaged.

"The lower and upper window sashes I6 and 23, as well as the lower and upper

storm window sashes

23 and 29 are provided with panes of glass therein in the conventional manner. When the window is in the position illustrated in Figure 1 of the drawings, a storm window is provided, acting as a double insulation. When ventilation is desired, the lower storm sash 23 may be raised into the position illustrated in Figure 2, and held in this position by any suitable means. When in this elevated position the window serves the pur.- pose of providing a screen window which may provide the desired amount of ventilation. The storm sash 23 may be held in any intermediate position as desired to provide a restricted amount of circulation.

In place of the separate channels 2| and angle strips 24, these two elements can be combined, as best shown in Figure 6 of the drawings. This View shows the two channels formed of a single piece of material. The ilange 44, base iiange 45, and intermediate ange 46 form the inner channel for the lower storm sash, taking the place of a channel 2|. The intermediate flange 41, base flange 49, and outer flange 50 take the place of an angle strip 24. The section is taken in the upper portion of the strip, as the outer channel, formed by

flanges

41, 49, and 50, are cut away in the lower portions of the frame in much the manneipreviously described in connection with the strips 24.
