WINDOW-SCREEN.

Specification of Letters Patent. .Pat nted lu j' lg 1916 Application filed June so, 1915. Serial no. 37,305.

window screen and has for its primary ob- Ject to provide means for enabling the screen to be easily and quickly fitted in the window frame and firmly secured in posi tion beneath the sash.

It" is another object of the invention to. provide a very simple and effective device of the above character, whereby the necessity of constructing the screen in relatively sliding sections is avoided and means provided in lieu thereof for readily effecting a tight and binding engagement of the screen with the window frame.

It is a further object of the invention to provide an improved window screen wherein the use of springs or analogous elements which soon lose their effectiveness, is avoided, and clamping means for the screen provided which may be applied to screens of the ordinary form now manufactured without necessitating any radical changes in the screen construction.

\Vith the above and other objects in view, my invention consists in the novel features of construction, combination and arrange ment of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a side elevation showing one of my improved screens mounted in the window beneath the sash; Fig. 2 is a section taken on the line 22 of Fig. 1; and Fig. 3 is a fragmentary elevation looking at the reverse side of the screen from that shown in Fig. 1 and illustrating the clamping bar in its released position.

Referring in detail to the drawing, 5 designates the screen frame which may be of any usual or ornamental construction and consists of marginal wood strips, indicated at 6, between which the wire screen fabric 7 is securely held. One of the vertical stiles.

of the screen frame is longitudinally channeled or recessed, as shown at 8. A bar 9 is also rabbeted or recessed, as at 10, to receive the reduced edge of the side bar or are pivoted at one of their ends, as at 12, upon one s de of the screen frame and are p'ivota'lly connected at'their opposite ends by P 5 S S 13 to the bar 9. Uponthe opposit'e'sideof the screen frame a lever 14 1s fulcrumed intermediate of its'e'nds on the screw 10. The outer end of 'th1s lever 1s 'pivotallyconnected by a pin or screw 16 to the bar 10, and by means of this lever said bar is adapted to be shifted with respect to the screen frame.

In the use of the invention, the lower window sash is raised and the screen fitted into the frame beneath said sash, the lever 14 being on the inner side of the screen. When the screen is placed in position, the bar 9 is disposed with relation to the screen frame in the position shown in Fig. 3. The operator now moves the lever 14 so that said bar is projected downwardly and laterally and into binding engagement with one side of the window frame. The screen is thus forced laterally and its opposite vertical edge engaged against the other side of theframe. l/Vhen the lever is in approximately horizontal position, as shown in Fig. 1, the

' ends of the movable bar 9 will be disposed.

in the same plane withthe upper and lower edges of the screen frame. The window sash is now lowered until the same engages stile of the screen frame. Spaced links 11 l upon the upper edge of the screen. In this manner, it will be seen that the screen may be very easily and quickly, as well as securely arranged in position beneath the window sash or removed when it is desired to close the window. The screens may, of course, be constructed in varioussizes and the movable bar 9 may be of any desired width and moved to a greater or less extent by means of the lever so that the screen can be fitted into windows of various widths within certain limits. From the foregoing description, the construction and several advantages of my invention will be fully and clearly understood. The use of the device requires no material alterations or changes in the ordinary screen construction and the additional cost entailed thereby is relatively small. The device is also very durable in actual use owing to the fact that no springs or other elements which mighteasily get out of order, are employed.

While I have shown and described the preferred construction and arrangement of theseveral parts of the device, it is to be understood that the same is susceptible of considerable modification and I, therefore,

reserve the privilege of resorting to all such v legitimate changes as may be fairly embodied within the spirit and scope of the inner side of the screen frame and pivotally connected at one end to the clamping bar on the corresponding side thereof and midway between the ends of the latter whereby the clamping bar may be shifted laterally --'with respect to the screen frame and engaged with the window casing, said lever and the links at all timesmaintaining-posi tlOIlS 1n parallel relation with respect to each. other.

In testimony whereof I hereunto aflix my slgnature in the presence of two witnesses.
