Be it known that I, JOSEPH ANGELETTI, a

residing at Kenoconsin, have j invented new and useful Improvements in Flexible Window-Screens, of

which the following is a specification. invention relates to improvements in flexi l e window-screens and it pertains more especially, first, to the peculiar eonstruction of the fabric comprising the screen, the strands of which are so formed and interwoven that the screen may be wound upon and unwound from a supporting-roller without'bending the wires of which the fabric is 3 constructed; second, to the peculiar con struction and arrangement o the screens with a window sash and sash-inCIosin frame,

whereby the screen is brought into t e window-frame as the window-sash is opened and My invention is further explained by reference to the accom anying drawings, in which V Figure 1 represents a front view with arts 1g. 2v represents a vertical section of 'a preferred form of my device in which the windowscreens are located, one above and the other. below the window-frame. Fig. 3 represents a modifiedform-of construction in which the screen-su porting rollers are located in a separate inc osure'fwithin the window-frame instead of above or below it,this modified form belng more especially adapted to be applied ously constructed, where it would be impracticable to place. the screen-suppqprting rollers outside the window-frame. ig. 4 repre sents a longitudinal, section of one of the an enlarged view of agportion of the screen, showing the manner of mterwinding or securing the wires of'which the screen is composed together;' and Fig; 6 represents a device for attaching the ends ofthe screen to the window-sash.'

Like parts are identified by the same refer: ence-letters throughout the several views.

A A represent the window-screens, one of which is preferablyused above and the other below the window.

B B represent the window-sash.

C is the Window-frame.

D is a screen-supporting roller.

connected with the ends of the 'dow-sash in any. convenient manner. This.

Fig. 5 represents Patented May 1,1906."

F is a rod-supportin bracket. The roller is made substantially Tike the ordinary curtain window'roller and is provided with a central aperture F for the reception of a spiral s ring G. The spiral spring G is rigidly afli ired at one end of the roller-supports ingrod E and at its opposite end to the roller D, as indicated in Fig. 4. The rod E is prevented'from turning 1n the bracket F by the set-screw H. One end of the screen 1s attached to the roller D by nails or in any other equivalent manner, and the opposite end is' attached to the window-sash, as indicated in Figs.1and6.

The upper and lower window-sash are preferably provided with a recess I forthe reception of the end of the screen, which is inserted therein and retained in place by a plurality of transversely-arranged pins J, as indicated in said Fig. 6.

In the preferred form (shown in Fig. 1) the screen-supporting rollers are located one below the window-sash and the other above the top of the Window, and the free endsof the screen are drawn through the respective slots K K of the frame and connected with the respective upper and lower sash-rails of the respective u per and lower windows.

It will e understood that preparatory to connecting the screens with the respective window-sash they are first wound upon their respective rollers. Their free ends are then opposing winbeing done, it will be understood that when the winwows are opened or moved away from the respective rollers the screens will be unwound therefrom, when the spiral springs G will be wound up by the unwinding movement of the screen. When, however, the windows are closed or moved in the opposite direction, the rollers will be caused to revolve in the opposite direction by the recoil of'the actuatlng-springs G, whereb the screens will be again wound upon sai supporting-rollers.

, Fonconvenience in attaching my screens to windows already in-use I have provided a se arate scr'een-in'closin'gbox or receptacle L, which is placed upon the window sillM, when the screen-sup orting roller is aifixed to the lower side of t e receptacle, L by the bracket F, when the sash is closed against said screenretaining receptacle. A similar receptacle L -may, if desired, be used at the upiper end of the window-frame and connecte with the upper sash, said screen-supporting roller and roo IIO

bracket being connected with the receptacle L instead of being connected with the window-frame, as shown in Figs. 1 and 2. Thus it is obvious that the modified form of con-' struction shown in Fig. 3 may be readily and quickly attached to the windows already in use simply by placing the receptacle L beneath or above the sash and connecting the free ends of the screens with the opposing their respective receptacles, and said receptacles Will serve as a place of storage for the screen when not in use.

Another advantage gained by my construction consists in the fact that when the windows are closed the screens are removed therefrom, and the light and view are not obstructed thereby.

The screens are only used and exposed to the weather when the windows-are opened, and when the windows are closed, as is usual in inclement weather, the screens are .removed and protected therefrom. While ordinary wire or other screen cloth may be used, I preferably form a screen of special construction in which the fabric comprisin the screen is free to be Wound upona cylin ical roller or unwound therefrom without bending the wires. To accomplish this object, the screen is referably made of a plurality of horizontal y-arranged spiral wires N, which are looped or interwound together, substantially as are the wires comprising the ordinary woven-wire mattress, while the free ends of. the respective wires are turned in wardly and looped together in pairs orsets.

of two each, as shown in Fig. 5, whereby each wire'comprising the fabric is free to turn independently of the next adjacent wire with which it is connected without bending the wire, owing to which fact the fabric comprisin the screen can be readily and freely woun upon a cylinder without bending the wires of which it is composed, and the liability of the wires becoming crystallized and broken, as would otherwise be the case, is

avoided, while owing to the eculiar manner of interlocking the ends o the respective wires together in sets of two each, as indicated, a smooth marginal edge of the screen is formed and the necessity of em 10 'ng a se arate binding for such margina e ge for ho ding the ends of the wires of which it is composed is avoided.

To prevent the respective screens from contacting with and chafing with the sides of the slots K of the window-sash or inclosure through which they are being drawn as they are wound u on and unwound from their supporting-r0 lers, I preferably provide the inclosure with oneor more longitudinal guiderollers O O, which serve'to guide the screen through the center of the slot as the windowsash are being raised and lowered.

To prevent burglars or others from entering a window, as they might otherwise do when the window-sash is raised, I have provided means for lockin the screen-supporting rollers D at several different points of adjustment, whereby the screen will remain taut,and it will be impossible for a person to enter the window without cutting the screen, while owing to the fact that the screen is composed of comparativly large wires it furnishes a substantial barrier to the admission of persons from the exterior.

As a means of locking the screen-sup ortin roller I have provided one end 0 the ro ler D with a plurality of sockets R for the reception of the fastening-pin P, which pin P has slidable bearings in the roller-inclosing case or wall S. Thus it is obvious that after the window is raised it is necessary simply to push the 1pinforward into one of the several sockets o the roller, whereby the roller willb'e-prevented from turning and the screen from being unwound therefrom. When,

however, it is desirous to close the window,

it is necessary simply to draw the pin B from thesocket, when the roller will be free to wind as the screenis released.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combinationof a window-sash; a window-screen; a screen-supporting roller; a radial flange provided with a lurality of recesses connected with one en of said roller; one end of said screen being attached'to said window-sash and the opposite end being attached to said roller; means for automatically winding said screen upon said roller as the same is released by the movement of the sash and a horizontally-moving locking-pin having slidable bearings in the window-frame adapted to engage the-recesses of said radial flange and lock the screen-supporting roller at any desired point of adjustment. In testimony whereof I aflix my signature in the presence of two witnesses.
