WINDOW-SCREEN.

SPECIFICATION forming pan: of Letters Patent No. 339,691, dated April 13. 1886.

Application filed February 2, 1886. Serial No. 100,642. (No model.)

To all whom, it may concern.-

Be it known that I, llIARGIOUS O. RADWAY, a citizen of the United States, residing at Ripon, in the county of Fond du Lac and State of YVisconsin, have inventeda new and useful Improvementin'Window-Screens, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in window-screens, and has for its object the provision of an article of the class named adapted to fit windows of difi'erent widths, as also those wherein one or both of the sides of the windowframe have been by accident displaced from its or their normal vertical position, to be quickly placed in proper position in the window-opening, securely held therein, and readily re moved therefrom, and also to combine cheapness of manufacture, durability of structure, and neatness of appearance.

To these ends the invention consists in the construct-ion, arrangement, and combination of the several parts for service, substantially as hereinafter described, and specifically pointed out in the claims.

In the drawings, Figure 1 represents a side elevation of a window-screen embodying iny improvements. Fig. 2 is a top plan view thereof. Fig. 3 represents detached detail views of parts of the improvement.

Referring to the drawings, in which similar letters of reference denote similar parts, A designates the frame of the screen, consisting of the top and bottom rails, a a, and end rails, a".

b designates a sheet of the ordinary screen wire placed upon one side of the frame A, and secured thereto by strips b of wood.

G designates springrails that operate at each end of the frame A, upon the surface opposite to that whereon is secured the wire cloth Z).

D designates the springs to which the rails C are connected, and by which said rails are operated. Said springs consist in straight portions (1, connected at their outer ends with the rails G, that move freely in longitudinal direction in loops or staples cl, affixed to the top and bottom rails, a e, at the ends thereof,

as shown, laterally-curved U-shaped spring portions (2", joined by a loop, (i with the parts (I, and straight parts (1*, the outer ends,

d of which are bent inwardly, for the purpose of holding, in connection with staples d, the spring firmly to the surface of the rail. The parts (1 d are in alignment, as shown.

I provide each corner of the frame with a spring, D, the U-shaped portion d of each of which projects toward the outer ed go of the top and bottom rail, respectively, as shown, and extend thepart d of said spring to and into the rails O at points (2 near the ends thereof, whereby great freedom of movement is imparted to said rails in lateral direction, and whereby either the upper or lower end of the rail 0 may be pressed outwardly to a greater distance than its opposite end, as shown by dotted lines in Fig. l. I deem this feature of importance, as thereby the frame or screen may be applied to windows having one or both of the sides of the window-frame out of position, and at angles other than right angles with the window-sill.

It will be observed that the rails G are held solely by the rods (1, and that said rails move freely upon the face of the frame.

The operation of my improvement will be readily understood without further description.

In order to define the nature and scope of my invention, 1 would state that hcretoioreit has been proposed to provide an adjustable window-screen consistingof an ordinary frame having guide-staples at its corners, laterallymovable strips for bearing against the windowframe, and arranged at the side of ,the end portions of the screen-frame and projecting beyond the same, headed guide-pins secured to the strips and working in the staples at the corners of the frame, and \l-shaped springs formed from a single piece of wire, and secured at their apices to the middle of the screen-frame and at their extremities to the movable strips.

In my improved device I employ the screenframe and the laterally-movable strips, and the strips are carried and pressed by springs D, of peculiar form, that are secured at each corner of the frame and I thus dispense with the use of separate guide pins and staples, as has been heretofore common. The springs are bent from a single piece of wire, and comprise two straight arms, that are connected by an intermediate curved or bow-shaped section, strips, and thearm d attached to the screenone of the arms being secured to the screenframe and the other arm to the movable strips. The arm 61 of each spring that connects with the strips is movable longitudinally and guided in staples that are secured to the frame, and by means of the curved section of the spring the arms d and the strips are normally forced laterally of the screen-frame, so as to hold the same very securely in the windowframe. I thus provide a removable and adjustable screen that can be easily and readily adjusted, and which can be i'nanufactured for a trifling sum.

I claim- 1. The combination of a screen-frame, the movable pressure-strips independent of the frame, and the springs carrying the strips, and comprising the horizontal arms (I (2, connected by an intermediate curved section, the arm d of each spring being secured to the arm (1* secured to the screen-frame, substan-.

tially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
