WINDOW-SCREEN.

Specification of Letters Patent.

Patented July 17, 1917.

Application filed May 1, 1916. Serial No. 94,824.

T0 all whom it may concern.'

Be it known that I, ANTONIO V. BRUN, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Window- Sereens, of which the following is a specilication.

This invention relates to improvements in window screens and has as its object the construction of a screen which will cover the entire window, but when not in use is rolled out of sight and does not obstruct the vision through the window.

Another object of my invention is to provide a screen which may be attached to windows of ordinary construction with the minimum expense and trouble; and

Lastly my invention aims to provide an improved screen which costs no more than the ordinary Xed or stationary screen as it is used on the outside of the window.

With these and other objects in view the invention consists in the novel construction, combination and arrangement of parts herein described, and more specifically pointed out in appended claims.

Reference being had to accompanying drawing forming a part of this specification,

Figure 1y is a view in vertical section through the window and screen.

Fig. 2 is a view in section through a window having a modified form of the screen.

Fig. 3 is a view in front elevation of a window showing my improved screen attached thereto.

Fig. 4 is an enlarged view in section through the window frame showing the track in which the screen moves.

Fig. 5 is a similar view of the track for the modiied form.

Fig. 6 is a view in section through the lower end of the screen.

Fig. 7 is an enlarged fragmentary. view of the lower corner of the screen.

Referring to corresponding parts in the several views by the same numerals of reference, 1 denotes my improved screen which has a width equal to the window and a length sufficient to entirely close the same. This screen is attached to a roller 2 of the type used in the roller window shades, this roller being mounted as hereinafter described. To the lower end of the screen is attached a double cloth of Aleather piece 10 which is stitched as at 12 forming two 1ongitudinal pockets 13 and 16 in which are held the strip 4 and a bar 11 respectively. The latter bar is provided with vprojecting ends which engage the trackways that act as guides for the edges of the screen. The side edges of the screen are provided with a binding 14 to eliminate wear and cause it to wind better upon the roller 2. In the binding 10 is provided one or more holes 15 suitably reinforced as by a buttonhole stitch.

A trackway 5 is attached to the window stop on each side, and extends upwardly to a point adjacent the top of window. The screen surrounding the roller 2 is provided with the cylindrical casing 6, having an opening 7 on the bottom, which at the side forms a substantial continuation of the trackway 5. The window stool is provided with hooks 8, the bent end of which is adapted to engage through the openings 15 above the wooden strip 4t, thereby holding the screen in its lower position.

The modied form of trackway shown in Fig. 5, is used when the screen roller is attached to the head casing of the window as shown in Fig. 2. This trackway is a Z-bar shape so that when one leg is attached to the window casing a groove 9 is formed in which the screen and rod 11 are adapted to slide.

In the form shown in Fig. 2 the brackets 18 for the window shade 17 are spaced a suiiicient distance apart to enable the screen to slide therebetween and the roller may be mounted upon brackets 19 and the casing 6 omitted. In the form shown in Fig. 1 the roller is mounted directly in the end plates of the casing, the one end of the casing having a cap 6 to permit the insertion of the screen.

The operation is as follows: When the window is open at the top, the screen is pulled down to the top of the upper sash, wherebythe opening is entirely screened and yet an unobstructed view is had throughl the glass. In case it is desired to have the lower sash raised then the screen is pulled down until the rod 16 rests on the window stool, thereby effectively screening the entire window. With easement windows the screen .is entirely unwound from the roller and fastened to the sill by means of hooks 8. When it is desired to close the windows or otherwise change the opening, this may easily be accomplished by unhooking the lower part4 of the screeny allowing the same to be Wound upon the roller in the manner of the ordinary shade.

In the modified form shown in Fig.k 2, the roller is mounted above the shade roller 17, W

` instalhbut otherwise is as efficient in operation; K

While I have shown the preferred embodi ment of my invention, it Will be understood that minor changes may be made in detail design' Without departing` from the spirit of the invention. Y

I claim as new and Wish to cover by Letters Patent Y l. A Window screen comprising a roller, a casing around said roller having' a tangentially disposed longitudinal slot, grooved guideways attached to the sides of said Window having'their grooves alining with the slot in said casing, a screen of flexible materialattached to said roller, an extension on the bottom of said screen of relatively non-porous material' said extension having traverse' pockets therein, and bars in said pockets having their ends engaging' said guideways; Y

2. A Window screen comprising a roller pivotally mounted at the top of the Win- I`he edges of the screen dow, a screen ofk flexible fabric material attached to said roller, a guideway for the edge ofl said screen attached to each side yof said Window, a reinforcing binding attached to each edge of said screen and engaging the adjacent guidevvay, an extension of relatively nonporous material attached to the bottom of said screen and having pockets formed therein, bars in said pockets engaging said guideways and means for holding said screen in its extended position.

3. A window screen' comprising a roller a casing around said roller having a slot in the bottom, grooved guideways attached to thesidesof said Window the grooves of said' guideivay aliningwith the slot in said casing, a screen of iiexible fabric attached to said roller, a reinforcing binding on the edges ofv said screen, an extension on the bottom' of said' screen having pockets'formed therein, stiffening bars extending through said'pockets With their ends engaging said guideways, said :extension havingy openings therein, and hooks adapted to engage said openings secured to the' sill: of said Window.
