CARL JOHAN JACKSON, OF SUPERIOR, WISCONSIN.

WINDOW.

Application filed July 19, 1923.

To all whom 2'2 may concern:

Be it known that I, CARL J CHAN JACKSON, a citizen of the United States, residing at Superior, in the county of Douglas and State of Wisconsin, have invented certain new and useful Improvements in Windows; and I do declare the following to a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in windows of the type in which a screen is movable simultaneously with one of the sashes to prevent entrance of insects while permitting ventilation by opening the sash.

The principal object of the invention is to provide a simple and inexpensive, yet a highlydesirable window construction of the class set forth, of such nature as to effectively rid the house of flies if any have entered through other openings.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings.

Figure 1 is an inner side elevation of a window structure constructed in accordance with my invention.

Figure 2 is a vertical sectional view on line 22 of Fig. 1.

Figure 3 is a vertical sectional view taken substantially on the plane of line 33 of Fig. 2.

Figure 4 is a detail vertical sectional view similar to the upper portion of Fig. 2 but illustrating the screen in its inoperative position.

Figure 5 is a horizontal sectional view as indicated by lines 55 of Figs. 2 and 3.

Figure 6 is a fragmentary perspective view partly broken away and in section, showing more particularly the construction of the upper sash which carries the screen.

Figure 7 is an inside elevation with the upper sash lowered and the screen in operative position.

Figure 8 is an outer side elevation show ing the appearance of the window when both sashes are closed.

Figure 9 is a detail sectional view taken on the line 99 of Fig. 6.

In the accompanying drawings which illustrate the preferred form of construction,

Serial No. 652,564.

the numeral 1. designates an appropriate window frame having a lower sash 2 of ordinary construction, an upper sash 3 of the special construction hereinafter described, and suitable guide strips A for the two sashes. The upper end of the frame 1 is provided with a downwardly opening pocket 5 into which the screened portion of the'upper sash 3, is movable when the window is closed, as seen in Fig. 4.

The upper sash 3 includes a lower end rail 6 and a pair of vertical side rails 7 rising therefrom, the outer edges of said rails 7, being formed with longitudinal grooves 8 terminating in the usual openings 9, said grooves being adapted to receive sash balance cords 10 which are provided with the well known sash balances 11, the lowerends of said cords being anchored in the openings 9, in any desired manner.

Each side rail 7 is formed with a vertical saw-cut 12which extends throughout a suitable portion of its length and opens through the upper end of the rail, through the inner edge of this rail, and through. the outer edge thereof, into the groove 8, said out 12,being preferably flush with the inner side wall of said groove.

A screen 13 formed of ordinary screen ire, preferably galvanized, is stretched between the two side rails 7 and passes outwardly through the saw-cuts 12, the vertical edges of said screen being bent laterally at 14, in the grooves 8, and secured at suitable intervals, as indicated at 15. Thus the grooves 8 perform the twofold function of receiving the anchoring means for the edges of the screen 13 and receiving the sash balancing cords 10.

A relatively narrow upper rail 16 extends between the upper ends of the side rails 7 and is rabbeted into the latter as indicated at 17, so as to be flush with the inner sides of said rails 7. A suitable number of vertical sash bars 18 extend between the bottom rail 6 and the top rail 16 and are cut away at one side of the screen 13, throughout the vertical width of the latter. Throughout the remainder of their lengths, the sash bars 18 co-act with the side rails 7 and the lower end rail 6 in securing vertical panes of glass 19 in place, the upper ends of said panes being in outwardly spaced overlapping relation with the lower edge of the screen 13, forming a gap 20 between said screen andpanes, through which flies crawling upwardly upon the panes may escape.

Reducing the upper ends of the sash bars 18 forms an upwardly facing shoulder 21 on each strip, adjacent the outer side of the screen 13, and when the sash 8 is raised so that said screen is positioned in the pocket 5 as seen in Fig. 4, these shoulders abut the lower edge of a sealing board 22 which is secured to one vertical side of said pocket. The lower edge of this board is provided with a longitudinal channel 23 to receive the upwardly projecting upper ends of the panes 19, as'disclosed in Fig. 4:, thus providing a tight seal which will prevent the entrance of cold air. The vertical ends 24 of the sealing board 22 are rabbeted to contact slidably with the rabbeted inner edges 25 of the vertical side rails 7, these rails being necessarily rabbeted in this manner to conveniently secure the panes of glass 19 in place.

In Figs. 7 and 8 I have illustrated the attractive appearance of the window both when the upper sash is raised and when it is lowered to position the screen for use. These views illustrate the fact also, that the window may be built into a building without interfering in any manner with the weather boarding or other external structure, nor with the plaster or wall board and the interior decorations therefor. The proportions in Figs. 7 and 8 are not identical with the other views but they show the general relation of parts and proportions which are preferably followed in practically carrying out the invention.

By employing the construction above described or a substantial equivalent thereof, a comparatively simple and inexpensive screened window is provided, yet one which will be highly advantageous in all respects. As excellent results are obtainable from the details disclosed, they may well be followed, but within the scope of the invention as claimed, minor changes may be made.

I claim:

1. A window structure comprising a frame having a downwardly opening pocket in its upper end, a sealing strip at one side of said pocket, said strip having its ends rabbeted and spaced. from the adjacent sides of the window frame, upper and lower slidable sashes in said frame, said upper sash comprising a lower rail, a pair of vertical side rails rabbeted on their inner edges for firm sliding engagement with the rabb'eted ends of said sealing strip and having sash cord grooves on their outer edges, a vertical saw-cut opening through their upper ends and inner and outer edges, a creen stretched between said vertical side rails and having its edge portions passed through said saw-cuts, bent laterally and secured in said grooves, and an upper rail to which said screen is secured said upper rail having its ends rabbeted into the upper ends of said side rails.

2. An upper window sash comprising lower rail, a pair of vertical side rails hav ing the usual sash cord grooves in the upper portions of their outer edges, and each having a vertical saw-cut opening through its upper end, through its outer edge into the sash cord groove, and through its inner edge, and a screen stretched between said vertical side rails and having its edge portions passed through said saw-cuts, bent laterally and secured in said grooves, an upper rail to which said screen is secured, a vertical sash bar extending between said upper and lower rails and having its upper portion cut away at one side of said screen throughout the height f the latter, and transparent panes held by said sash bar and said lower and vertical rails, said panes extending above the lower edge of the screen in out wardly spaced relation with the latter.

In testimony whereof I have hereunto aifixed my signature.

CARL JOHAN J ACKSON
