This invention relates to window screens and with regard to its morespeeificffeatures CO'WlIlClOW screens adapted to cover an irreglilar shaped opening.

An object of th is invention'is to provide an adjustable 'window screen adapted to cover a semi-cireular shaped opening.

A further obj eet of the invention is to pro vide a device of the character described having louvres which may be moved from'a position to screen the opening to position such as will permit the passage of light and A furtheroobject of the invention is to provide a device of the charaeter'described which will be c simple in construction, economical in manufacture and eflieient in operation. I

Other objects'will be inpart Obvious and in part pointed out hereinafter. I I ,The inyentionaccordingly consists in the features of construction, combinations of elements andgarrahgement of: parts "which Wvill be exemplified in the construction hereinafter set 'forthpand 'the scope iof the appli- 'cation of whichwill be "indieated in the fol lo wing' jelaims.

I I While many of the features of this inven- Yt'ion' are of general application, particular advantages are'obtained'w'hen the invention isfembodied in a screen adapted to protect a semi-circular, opening,' anclfor that reason I 1 represents a fraiiiei 6f" the aIfi i illustrated, i this l a piece s; attachedatitsb as theendsfo flanges of the channel inemb Lally common, center offinclinati on a "the slats "vi ill' be substantially members ,3 ande, and they Willbeso f1anje,, tljey will 'co' operate f'to 'lose opening. j 'Theyi niay bear'id'jasi st; d, are} adapted-to, overlap in either extreme position I L I name-an eonstructionzfor" these 1 V oates a block d'isposed 'at that homer 0 triangle which is to I assembled "screen.

This may be made by bending the material of one side of the frame upwardly to form the pivot and attaching the material of the other side thereto to form a shoulder; or the frame may have its top member integral and the pivot may comprise a short tubular portion fitting over the top member and carrying the pivot. This short member may be fastened to the top member in any suitable manner as by being crimped thereon. The pivots and 17 are co-axial with each other and may, as in the illustration, be

I disposed on the center line of the louver.

Means are provided for oscillating, or rotating all of the louvers on their pivotal axes in unison comprising, as illustrated, an arcuate member 19 substantially concentric with the members 3 and 4. connected with a corresponding portion of each louver not on the axis of the pivot, so as to move toward and from the frame member 1, and occupy a plane concentric to it when the screen is closed. As illustrated, the frame 10 is provided at one corner with an eye 20and passing through the eye 20 and connecting the eye pivotally with the member 19 is a loop or link 21. A suitable cord may be provided for operating the member .terial through for the supports as shown in Fig. 3.

19, which will preferably be attached to the next louver to the end. so that the cord will not interfere with the complete closing of the screen.

In order to avoid interference between the members 11 of adjacent louvers, each alternate louver may have its neck 14 longer than the neck of the adjacent louvers whereby the inner ends of these alternate louvers will be spaced sufficiently from the center of the member 4 and alternately terminate at different distances therefrom so that the members 11 of adjacent louvers do not interfere with each other.

Each of the frames 10 may be covered with any suitable sheet material such as glass, metal or wood, but a convenient mafor the purpose comprises cotton duck, which may be sewed to the framework as well as to the pivot members openings in the latter. To strengthen the louver the frame may be braced by a tie wire 20. y

The lower channel member 2 may be of sufiicient width to serve not only as support for the member 4, but also as a track of a lower screen or drapery This lower screen may comprise a plurality of flexible louvers 25 each attached to blocks 26 at its ends, and provided with members 27 at its center. Each of these blocks may be attached to rigid vertical members 28 at both front and back.

A rectangular rod 29 may extend parallel to the channel 2, and have mounted thereon for horizontal but not rotative movement brackets 30, to the front and back of which the ends of the members 28 may be connected, whereby when the rod is rotated the slats are rotated with the rod to open or close the screen.

The brackets 30 may have supporting arms as shOWn at 32, carrying anti-friction rolls 33 which may engage a flange 34 of the channel 2 to support the screen from the channel 2.

Operating cords as 35 may be attached to the brackets 30 by which they may be moved horizontally to collapse the collapsible louvers and remove the screen from before the opening.

A latch as 36 may be provided for holding the vertical members in extended position.

By this construction, by pulling on the cord 85, the vertical members atone side will be moved longitudinally of the channel whereby the screen will be removed from before the opening.

Means are also provided for coverin the central space around the members 4' an the pivot members 11, which may take the form of a rosette, as shown in Fig. 1.

The manipulation of the screen will be obvious from the description of its construction. By the movement of the member 19, all of the louvers will be simultaneously rotated each about its pivot whereby the louvers may be all brought substantially into the plane of the frame 1 or may be moved to a position perpendicular to that plane thus either substantially wholly excluding the passage of air and light through the screen or freely permitting such passage.

Thus by the above construction are accomplished among others the objects hereinbefore set forth.

As many changes could be made in the above construction and many apparently widely different embodiments of this in vention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and'not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention, which, as the matter of langua e, might be said to fall therebetween.

H aving described my invention what I claim as new and desire to secure by Letters Patent is 1. A window screen comprising, in combi nation, a semi-circular frame, a plurality of radially disposed slats pivoted in the frame on radially disposed pivots, a semi-circular member and means for connecting the end of each slat distant from its pivotal center with said semi-circular member. 2. A window screen including, in combination, a plurality of slats, pivot members having slat engaging portions pivotally supporting said slats, adjacent slat engaging portions of said pivot members being relatively offset so as to avoid interference in the operation thereof.
