Letters Patent No. 113,537, dated'April 1l, 1871.

VIMPROVEMNT IN WINDOW-SCREENS.

' The Schedule rean-ed to in these Letters Patent and making part of the same.

To all whom 'it may concern Be it known that I, CHARLES F. LINSCOTlgVof Chicago, in the county of Cook and State of Illinois, have invented a new and useful Adjustable Window-Screen; and l do hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which my invention apper tains to make and use' the same, reference being had to the accompanying drawing forming a part'of this specification. A

Figure l is a plan view ot'fr'ny improved windowscreen extended to its fullest capacity, and partly broken away to show the construction.

Figure 2 isa longitudinal section ofthe same in the line x :11, fig. l.

Figure 3 is a plan viewl of one of the adjustable slides applied to a section of thel main frame..

Similar letters of reference indicate corresponding parts in the several figures of the drawing.

My invention has for its object-to proyide a window-screen which can be adjusted laterally for .adaptation to windows of diiierent sizes; and, to this end,

It consists, primarily, in the arrangement, with the main screen, of supplemental frames and screens, of peculiar construction, adapted for adjustment to accommodate windows of differentl sizes upon opposite sides of the main frame, as will be hereinafter more fully described.

In the accompanying drawing- A is a quadrangular or other suitably-formed frame, composed of wood or other proper material, and covered with a wire or netting screen7 B. v

Upon opposite sides or edges ot'. the main frame supplemental frames are formed by means Voi' the rails O, secured to the main frame between the outer ends of metallic slides I).

These slides are each struck up' with side flanges,

lwhich iit over the top and bottom rails ot' the main '-frarne, and with a central tongue, E, adapted to vit and slide within grooves formed in the edges of said rails.

The spaces between the rails C and main frarne are filled with wire-gauze or mosquito-netting, as found desirable. v

In fig. 1, the screen 'F is composed of wire, and in order to adapt the same for folding up, it is creased or bentvto form folds similar to the folds of a fan, as

shown at G, iig. 2, to admit of its being closed within a small compass when the rail G is movedtoward the main frame, :is shown in dotted lines, iig. l.

Ihe screen H, also shown in iig. l, is formed of netting, one edge being secured to the side ci' the main frame and the oppositaedge to a roller, l, placed within a circular recess in the inner edge of the rail C, and having its bearings in the metal slides.

When this rail is moved, toward the main frame to the position shown by dotted lines the netting is rolled upon the roller by any suitable means applied to thev journals of the latter.

In this example vof my invention I have shown screws 'J in the journals of the roller, projecting through the vmetal slides, which, being operated by a screw-driver, turn the roller to Wind up the netting. The netting is, of course, unwonnd by the act of extending the supplemental frame..

'lhesupplevmental frames are locked in a closed or extended position by means of the adjusting-screws Kin the Ymain frame, passing through longitudinal slots L in the slides, as shown in iig. 3.

The anges upon the slides EV extend over the upper and lower ends of the screens inthe supplemental frame, toprotect the same and to exclude dirt or insects.

If desired, the slides may be formed without the anges and tongue; but I prefer this construction, as' it serves to render their operation more uniform and exactl p By my invention I am enabled to supply windowscreens to the trade which can'be adjusted to any sized window with the utmost accuracy and despatch.

I design to manufacture them injthree sizes, to include the small windows oivdwelling-houses and the larger windows of stores, &c.

A special advantage derived from the construction of my improved screen is that the main frame, occu- `pying comparatively a large space in the center'of the screen, the view through the netting or gauze is un obstructed by the rails or other parts of the supplemental frames.v l i I do not claim, broadly, an adjustable windowscreen, as I am aware the same isnot new.

' yHaving thus described my invention,

W'hat I claim as new, and desire to secure by Letters Patent, is

1'. rIhe supplemental frames and screens, arranged for adjustment upon opposite sides of the main frame,l substantially as shown and described, for `the purpose specified. Y 2. The combination of the `folding wire-screen F, with the supplemental frame and the main frame A, substantially as described, for the purpose specified.

3. 'Ihe combination ol" the roller I with the supplemental frame,rthe netting-screen H, and the main frame A, substantially as described, for the purpose specified.

4. The adjustable slides D, constructed substantially as described, in combination with the rails C and the main frame A arranged as shown, for the purpose specified.
