AUTOMATIC SCREEN FOB WINDOWS.

Specification of Letters Patent.

Patented Apr. 16, 1918.

Application filed May 24, 1917. Serial No. 170,718.

To all whom it may concern:

Be it known that I, RALPH H. POWERS, a citizen of the United States, and a resident of Port Huron, in the county of Saint Clair and State of Michigan, have invented a certain new and useful Improvement in Automatic Screens for Windows, of which the following is a specification.

The present invention relates to wmdow screens and has for an object to provide a screen for attachment to the top or bottom or both of a window, and to be engaged w1th the one or more sashes therein for screening the opening through the window when the sash is moved into open position.

Another object is to provlde a screen of the roller type which is. spring actuatedto withdraw the screen into a casing or the like out of the way when not in use, and toexpose only a portion of the screen suflicient to block the opening in the window to the passage of insects, flies and the like.

A further object of the invention is to provide means for guiding and retainlng the adjustable screen' in close fitting engagement with the window at all ad uStments of the screen with the sash, which retaining means is adjustable to accommodate windows'varying within practical limits in width so that the automatic screen of this invention may be applied to practically all types of windows now in common use.

The above, and other objects and advantages of this invention will be in part described, and in part understood, from the following detailed description of the present preferred embodiment, thesame being llustrated in the accompanying drawmgs, wherein:

Figure 1 is an outer side elevation of a window having automatic screens constructed according to the present invention applied to the top and bottom thereof.

Fig. 2 is a fragmentary, enlarged, vertical section taken through the lower portion of a window having the automatic screen applied thereto.

Fig. 3 is a fragmentary side elevation of Fig. 6 is adetail enlarged transverse sectlon taken through the screen sections, show- 1ng"the'spring therein for re-winding the screen, when the latter is relaxed by the placing of the sash.

Fig. 7 is a detail enlarged view of the screen roller, showing a mean v for fastening the inner edge of the screen to the roller.

Fig. 8 is a fragmentary enlarged section taken vertically through the lower portion ofa window casing and a sash in closed position, showing the screen casing and the screen In posltion.

Fig. 9 is a fragmentary view of a section of the flexible screen and frame therefor, showing a modification in the structure thereof.

Fig. 10 is a horizontal section through the same and through a modified form of guide therefor.

Flg. 11 is a detail perspective view of one. of the guide rails for the screen.

Fig. 12 is a fragmentary plan view of the lower end of the modified form of screen, enlarged, showing the flaring mouth of the guiding groove in the screen-frame.

Fig. 13 is a transverse section through the lower portion of a window casing, showmg a modified construction and mounting of the screen casing.

Fig. 14 is a detail perspective view of a section of the modified form of screen, showing the hinged joint between the sections thereof.

.Referringto these drawings, wherein like parts are designated by similar characters of rcference'throughout the several views, 10 designates acasingwhich may be formed from sheet metal and which is secured at its base portion upon the inner sillstrip A of the window,and which is preferably flush at its'outer closed side with the outer edge of the strip A. The casing 10 is providedwith' a longitudinally extending o'pening in'iits" top adjacent to its outer side through which the flexible screen of the invention is adapted to extend.

. The casin l0' is provided therein with a longitudinal y extending roller 11 about which the screen is adapted to be rolled, the latter being secured to the roller 11 by the provision of an attaching strip 12, as shown in Fig. 7, which clamps the inner edge of the wire meshing portion of the screen longL tudinally against one side of the roller 11.

The wire mesh portion 13 of the screen is reinforced and held in position at its opposite edges by the provision of a flexible frame, the same comprising series of hingedly connected blocks 14 transversely registering and adapted to be rolled upon the roller 11.

The outer free end of the wire mesh body 13 is provided with an attaching strip 15 having a series of transversely elongated slots 16 adapted for insertion over turn-' buttons 17 which are placed upon the lower bar of the sash B of the window. The roller 11 is normally urged in turn in a direction to wind the flexible screen thereabout by means of a spiral spring 18 located in one end of the casing 10. One end of the spring 18 is secured by rivets or the like to the roller 11, and the opposite end of the spring 18 is secured to the casing 10. When the sash B is raised, the flexible screen is drawn out of the casing and unwound from the roller 11 to an extent suflicient to close the opening between the casing 10 and the adjacent bar of the sash B.

The flexible frame of the screen is held in close contact with the opposite sides of the window by the provision of a pair of guiderails 19, the same being of channel form and having the grooves thereof facing inwardly opposite one another, and being of, a size to freely receive the block 14 of the flexible frame therein. The guide rails 19 are-provided with laterally extending flanges 20 throughout the length of the rails 19 adapted to bear against the inwardly ex tending flanges of angle-irons 21 which are secured, by screws or the like, against the inner opposite sides of the window casing. The said flanges of .the angle-irons 21 project inwardly toward each other and are adapted to lie against the guide ralls of the sash B when the latter are in position. The flanges2O of the guide rails 19 and the abutting flanges of the angle-irons 21 are provided with transversely extending elongated slots adapted to receive retaining bolts 22 therethrough which are preferably countersunk in the inner faces of the angleirons 21 and provided upon their outer ends with wing nuts 23 or the like for binding the guide rails 19 in adjusted position upon the angle-irons 21 when the guide rails 19 are moved taut and from each other into the desired adjusted position. By thus adjustably mounting the guide rails 19, the latter may be accommodated to screens varying in width and to windows of various sizes. The guide rails 19 thus hold the lateral. edges of the flexible screen from bulging outwardly from the window casing, and seal .the spaces between the flexible screen and the casing.

It is of course understood that the automatic roller screen thus far may be applied to the top of the window casing and attached to the top bar of the upper sash thereof, as shown in F ig. 1, so that the flexible screen is drawn downwardly when the upper sash is moved into open position. In this instance, the guide rails 19 are arranged about the outer side of the window casing to hold the flexible screen from bulg ing outwardly, and for sealing the spaces at the opposite edges of the screen.

In the modification disclosed in Figs. 9, 10, 11, 12, and 14, the side bars of the frame of the flexible window screen are com posed of pivotally connected blocks l4: having in their outer sides, a vertically extending groove 21which, as shown in Fig. 12, flares at the lower end of the lowermost block 14 to provide an entering throat 25. The blocks 141 are adapted to fit between the flanges 26 and 27 of opposed guide rails which are mounted upon the angle-irons 21 secured to the inner opposite sides of the window casing. It will be noted from Fig. 10 that in each instance, the outstanding flanges 28 of the guide rails lap over against the inner sides of the angleirons 21, and that the flanges 26 are adapted to lie close against the opposed and lower bars of the window sash.

The wire mesh body of the modified form of screen is preferably made up of a plurality of transversely extending sections 29, one section for each opposite pair of blocks 14. The sections 29 are not adapted to flex about the roller when wound and as shown in Fig. 14, are hingedly connected together by links 30 which lie closely together and complete the wire mesh body portion of the screen. These links 30 admit of the rolling of the screen body about the roller and are bent or hinged in the transverse plane of the hinged connection of the block 14.

In Fig. 13, the window casing is provided with space-apart strips 31 and 32 and an inner facing strip 33, the strips and the sides of the window casing forming an inclosure or boxing adapted to receive the casing 10 of the roller screen. The top strip 31 is provided with an aperture through which the flexible screen is adapted to ex tend, the screen being attached to the sash of the window in the manner above described.

It is of-course understood that various other changes and modifications may .be made in the details of construction and design of the above specifically described embodiment of the invention without ,departing from the spirit thereof and being restricted only by the scope of the following claims. 1
