SCREEN.
Specification of Letters Eatent.
Patented July 15,
Application filed November 11, 1918. Serial No. 261,951.
To all whom it may concern Be it known that I, CHARLns S. SMITH, a citizen of the United States, residing at Chicago, in the county of Cook and State of lllinois, have invented certain new and useful Improvements in Screens, of which the following is a specification. i
This invention relates to screens of the kind that is used adjacent windows. More particularly, it is of the roller type; that is, it is of the type that is mounted upon a. spring roller so as to wind thereupon when not in use. The screenis so arranged with respect to a. window sash that it automatically unrolls as the sash is opened, and rolls up again as the sash is closed.
Vith a View to the production of a screen of this kind, I have aimed to device a structure that is simple, compact, and relatively inexpensive. Further, it has been an object of this invention that the screen should be easily secured in operative position, and
just as easily removed therefrom. A connection between the screen andsash has, furthermore, been arranged such that it is difficult, if not impossible, to remove the screen while the window remains open, but with complete closing of the window its removal may be readily accomplished.
In the description to follow, other objects, purposes, and uses of my invention will become apparent. A structure in which is represented the improved features of my screen is shown in detail in the accompanying drawings wherein- Figure 1 is an elevation of a window frame in which is a sliding sash shown partly open, and the present screen partly unrolled; I I
Fig. 2 is a transverse section, enlarged, through the screen, together with the ad acent parts of the window, the screen in thls view being partly unrolled as in Fig. 1;
Fig; 3 is a view SlmilfilftOFlg. 2, except that the screen is shown as completely rolled up, the sash in this view being completely closed; I I I;
Fig. 4 is a horizontal section through the case taken on line 4-4 of Fig.3; and
Fig. 5 is a detail in elevation of the hook secured to the sash which makes connection with the screen.
It is desirable that the present screen should be adequately protected, andfor this "purpose I have provided an inclosmg case consisting of a bottom 10, a back 11 usually at. right angles thereto, and a combined front and top piece 12 suitably rounded or curved as shown in Figs. 2 and 3. Ends 13 are also provided in which are .mounted trunnions of a roller 1 which may be hollow or otherwise, and which is preferably operated against the tension of a coiled spring 15. Formed in the bottom of the case are key-hole slots 16, as many as necessary, through which extend screws 17 secured to the sill of the window frame, to lock the case in operative position adjacent thesash. As this form of connection is well known, further description thereof is unnecessary.
Arranged uponthe roller and within the case is a screen 18 of any suitable material, and by preference sufiiciently flexible to wind upon the roller as many times as necessary. The free edge of the screen is reinforced with a strip 19 suitably fastened in place and bent over and upon itself in the form of a hook to provide a channel 20. In order thatthe screen may unroll and roll up again upon the roller within the case, I have provided a slit 21 lengthwise thereof in the top piece 12 adjacent the back 11, and as the screen is'wound upon the roller, its free edge approaches the upper edge of the back- 11 until finally the reinforcing strip hooks thereon as shown in Fig. 8.
The construction of the screen having been described in detail, I will now explain its cooperation with the sash. The means for accomplishing this is exceedingly simple, consisting of one or more hooks 22 (a single hook only has been illustrated as one will commonly suffice) secured to the lower rail of the sash and so shaped as to present an upwardly extending tongue which is offset or otherwise formed'to stand out slightly from the sash. When the window is closed,
as shown in Fig. 3, this tongue will lie behook 22 enters the channel 20 formed in the strip 19. By preference a slit 23 is formed 1 in the bend of the strip such that the tongue of, the hook 22 may enter therein (see Fi 2) to correctly engage with the screen. t will be manifest, of course, that the parts so formed connect the screen to the sash, so that the screen will be unwound and rise with the sash to occupy the space in the window frame that is vacated by the sash as it is moved upwardly. Conversely, the screen is lowered and rewound within its protecting case as the sash is lowered. It may be found expedient to arrange upon the inside stops which guide the sash'inits movements, small strips 24, as shown, which overlie the side edges of the screen when it is raised, thus closing what otherwise would be open spaces,.rather narrow to be sure, butundesirable nevertheless,
I have shown and described the present screen. in relation to the lower sash of a window; it-is obvious, however, that it may be used in connection with the upper sash as well by making the proper reversals in position. Other uses may also be found for a.
screen constructed in accordance with my invention, and these, as well as any modifications or changes in detail which embody my improvements as defined in the appended claims, I desire to include within the scope of this patent.
I claim:
1. In combination with a window sill and a sliding sash, a casing mounted on the sill, a spring roller rotatably mounted in the easing and carrying a flexible screen, the front edge of the casing normally resting in proximity to and extending parallel to the sash, a slit in the top of the casing, adjacent the front edge thereof, through which the screen extends, a downwardly facing channeled strip carried by the free edge of the screen and provided with a flange extending downwardly between the casing and sash and adapted, to engage and overhang the top of the front edge of the casing, when the screen is in its inoperative position, and means on the sliding sash for engaging said strip when the sash is raised, substantially as described;
2. In combination with a window sill and front edge of the casing'normally resting in proximity to and extending parallel to the sash, a slit in the top of the casing, adjacent the front edge thereof, through which the screen extends, a downwardly facing channeled strip carried by the free edge of the screen and provided with aflange extending downwardly between the casing and sash and adapted to engage and overhang the top of the front edge of the casing, when the screen is in its inoperative position, and means on, thesliding sash for engaging said strip when the sash is raised, and for releasing said clip when the window is closed and the clip contacts the top ofthe casing, substantially as described.
3. In combination with a window sill'and a sliding'sash, a casing mounted'on the sill, a spring roller rotatably mounted in. the casing and carrying .a flexible screen, the front edge of the casing normally resting in proximity to and extending parallel to the sash, a slit in the top of the casing, adjacent the front edge thereof, through which the screen extends, a downwardly facing channeled strip carried by the free edge of the screen and provided with-a flange extending downwardly between the casing and sash and adapted to engage and overhang described.
