AT TOENE Y 5 Patented May 6, 1952 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to roller screens and has for one of its objects the provision of improved means in a `roller screen installation for protecting the screen against the elements when the same is rolled up within its housing but is connected with a window for withdrawal when the window is opened.

Another object of the invention is the provision of improved means in a roller screen installation for mounting the screen in a window opening, and for guiding the screen during its movement to and from a position extending across a window opening.

A still further object of the invention is the provision of improved means in a roller screen installation for connecting and disconnecting the screen to the window.

Heretofore it has been common practice to support the spring wound roller screens within an elongated housing that in turn is secured to the sill of the window fr-ame for a lower vertically slidable window, or to one or both of the jambs or vertical side frame members of horizontally slidable windows, or to the upper head piece of the frame'ior the upper one of a pair of vertically slidable windows.

While the present invention is adapted for use with sliding windows of any of the above types, it will be shown as applied to only the lower of a pair of vertically slidable windows because this is the usual and most common structure.

A roller screen housing of the above type is formed with a slot in common practice, which slot may open outwardly of the upper side of the housing. rThe screen extends through this slot to its connection with the window, which con nection is usually made with the lower side of the sash.

Heretofore little if any protection has been aiforded for the screen in the housing. During wet and windy weather the window is usually closed and at that time rain and dirt have usually entered the housing through the upper slot resulting in damage to the screen, or at least, to its appearance.

With the present invention, simple means is provided on the screen for substantially closing the slot when the window is closed, and for deecting dirt and draining water away from the slot.

Also heretofore difficulty has been encountered in providing simple and easily operated means for connecting and disconnecting the screen from the window frame. Inasmuch as the screen is outside the window, the connecting and disconnecting of the same with the frame from Within the houses has presented a problem.

With the present invention, the manipulation of the window by a person inside the room is all that is required. To secure one disconnected screen to the frame, it is only necessary to fully lower the window, and to disconnect the same and to sharply move the window to -a fully open position. A resistance to such movement to fully open position is established at the nal inch of movement or fraction thereof when the Window is moved to fully open position. In the normal opening of the window there is no effect on the screen, it will remain securely fastened to the window, but a fairly sharp hard nal movement, will disconnect the screen from the window.

Other objects and advantages will appear in the description and in the drawings.

In the drawings, Fig. 1 is an elevational view of an opened window with the present invention installed thereon, which view is from the outside of the window. A portion of the roller screen housing is broken away.

Fig. 2 is a horizontal sectional view, partly broken in length, showing the parting strips of this invention in the conventional sides of a window frame where they have replaced the conventional solid strips.

Fig. 3 is a vertical sectional view taken along line 3-3 of Fig. 1.

Fig. 4 is an enlarged fragmentary View of the outer end of the roller screen showing the shield for the slot in the housing, and also showing the means for securing the screen to the frame.

Fig. 5 is a fragmentary elevational View of the upper end of one of the parting strips showing the stop for releasing the screen from the Window frame.

Fig. 6 is an enlarged sectional view through the roller housing.

In detail the screen as illustrated herein is adapted to be secured to the sill I of a window frame having opposed vertical sides 2, 3 and a lintel or head piece 4. Upper sash 5 and lower sash 6 are adapted to reciprocablyslide vertically in the frame in the usual manner.

The side frame members 2, 3 is the conventional window structure, are formed with parallel opposed channels or grooves 'i in which solid parting strips are secured for guiding the upper and lower windows along paths adjacent each other.

In the present invention these parting strips alongside the lower window are removed, and are substituted by elongated-generally tubular members 8 that are rectangular in cross-section.

The opposed sides of said members are slotted engage with member 22 and securely but releasat 9 longitudinally thereof adjacent one of the ably connects screen I I to sash 6 through the adjoining sides of said member, and stops III are spring action of clip 28 on projection 21.

End plates I4 of the housing I3 are prol5 contracted position with shield 25 covering slot vided with holes I5 for securing the ends of roller I3. It should be noted in this connection that lip I2 in the usual manner. 20 on housing I3 besides serving to exclude rain Said elongated housing I3 is substantially and dirt from slot 2| also serves as a guide upon square in cross-section having a bottom I6, a top which screen I I may slide thus further preventing I'I, side walls I8 adjacent groove 'I and side wall 20 the entrance of foreign material through slot 2i I9 remote from said groove.
